The benefit of 2016-086052 is described in the specification by reference to the whole.

在安裝於建築物牆璧面或天花板等之設置面的機器，有時會具有藉由安裝板來固定機器本體之情況。如此之機器，譬如可舉出火災警報器或氣體警報器。其中火災警報器，藉由火災所產生之煙霧或熱氣或者藉由感應器偵測出火焰，若偵測火災的話，就會藉由聲音或光等發出警報。A machine attached to a setting surface such as a wall surface of a building or a ceiling may have a case where the machine body is fixed by a mounting plate. Such a machine can be exemplified by a fire alarm or a gas alarm. The fire alarm detects the flame by smoke or hot air generated by a fire or by a sensor, and if a fire is detected, an alarm is sounded by sound or light.

安裝板，對著建築物之設置面抵接其中一面，成為被固定之面，讓另一面成為可固定機器本體之面。將機器本體安裝於設置面之際，首先，對設置面以螺固安裝板，對所固定之安裝板安裝固定機器本體。作為由安裝板及機器本體所構成之機器安裝構造，譬如可舉出專利文獻1之記載。The mounting plate abuts one side of the installation surface of the building to become a fixed surface, and the other surface becomes a surface on which the machine body can be fixed. When the machine body is mounted on the installation surface, first, the installation surface is screwed to the mounting plate, and the machine body is fixed to the fixed mounting plate. As a machine mounting structure which consists of a mounting board and a machine main body, the description of patent document 1 is mentioned, for example.

於火災警報器之框體內，設置有一用來發出聲音之揚聲器。從揚聲器可發出偵測到火災時之警報等。揚聲器係被固定於框體內，於框體前面部，於與揚聲器為對向之位置上形成有一聲音孔。來自揚聲器之聲音，係經過聲音孔而傳送到框體之前面側。作為如此之火災警報器，譬如可舉出專利文獻2之記載。A speaker for sound is provided in the frame of the fire alarm. From the speaker, an alarm can be issued to detect a fire. The speaker is fixed in the casing, and a sound hole is formed at a position facing the speaker at a front portion of the casing. The sound from the speaker is transmitted to the front side of the frame through the sound hole. As such a fire alarm, for example, the description of Patent Document 2 can be cited.

於主要被設置於住宅的火災警報器，由於可簡單地進行起初之啟動電源，或定期性進行的動作測試，或者警報時之停止警報之操作，所以於框體前面設置有操作鍵。利用按壓操作操作鍵，可按壓火災警報器內部之按鈕開關而進行各種操作。另外，於操作鍵上具有設置拉繩之安裝部。當於高處設置火災警報器等情況時，可利用將拉繩安裝於操作鍵且利用拉引拉繩之動作而進行操作鍵之操作。作為具備如此之操作鍵之火災警報器，譬如可舉出專利文獻3之記載。In the fire alarm that is mainly installed in a house, an operation key is provided on the front side of the casing because the initial start of the power supply, the periodic operation test, or the operation of stopping the alarm at the time of the alarm can be easily performed. By pressing the operation button, various operations can be performed by pressing the push button switch inside the fire alarm. In addition, a mounting portion for the pull cord is provided on the operation key. When a fire alarm or the like is provided at a high place, the operation of the operation key can be performed by attaching the drawstring to the operation key and using the operation of pulling the drawstring. As a fire alarm having such an operation key, for example, the description of Patent Document 3 can be cited.

火災警報器，係被設置於建築物之牆壁面或天花板等之設置面，藉由感應器偵測藉由火災所生之煙霧，若偵測火災的話，就發出藉由聲音或光所產生之警報。於火災警報器中之煙霧之偵測，係藉由具有發光部及感光部之煙霧偵測部所形成。感光部，於煙霧偵測部之中，係以不直接入射來自發光部之光之方式來配置。當煙霧飄入到煙霧偵測部內之情況時，會因為煙霧來分散來自發光部之部分光，藉由於感光部感光到該分散光，就可偵測出煙霧之存在。煙霧偵測部，由於係以如上述之原理偵測出煙霧，所以必須不能讓來自外部之光進入到煙霧偵測部。因此，以覆蓋煙霧偵測部之區域之方式，設置煙霧偵測部蓋體。.從基部開始讓豎立之璧部沿著圓周方向設置有複數個煙霧偵測部蓋體。藉由該璧部來遮掩來自外部之光，進而防止入射到感光部。作為具有如此之煙霧偵測部蓋體之火災警報器譬如可舉出專利文獻4記載。The fire alarm is installed on the wall surface or the ceiling of the building, and the smoke generated by the fire is detected by the sensor. If the fire is detected, it is generated by sound or light. alarm. The detection of smoke in the fire alarm is formed by a smoke detecting portion having a light emitting portion and a light receiving portion. The light-receiving portion is disposed in the smoke detecting portion so as not to directly enter the light from the light-emitting portion. When the smoke floats into the smoke detecting portion, part of the light from the light-emitting portion is scattered by the smoke, and the light is detected by the photosensitive portion to detect the presence of the smoke. In the smoke detecting unit, since the smoke is detected by the above principle, it is necessary to prevent the light from the outside from entering the smoke detecting portion. Therefore, the smoke detecting portion cover is provided so as to cover the area of the smoke detecting portion. Starting from the base, a plurality of smoke detecting portion covers are arranged along the circumferential direction of the upright crotch portion. The light from the outside is blocked by the crotch portion, thereby preventing entry to the photosensitive portion. A fire alarm having such a smoke detecting unit cover is described in Patent Document 4, for example.

另外，習知上，有揭示一種光電式煙霧感測器（譬如茲參考專利文獻5），其係配置於監視區域之設置面，偵測該監視區域內之煙霧而進行警報者。如此之習知光電式煙霧感測器，大致上，具備有發光元件，感光元件，感光透鏡，偵測部本體及煙霧偵測部，從發光元件，讓感光透鏡聚光基於在於藉由偵測部本體及煙霧偵測部所區隔之偵測空間所發光之光的煙霧偵測部內之散亂光，讓感光元件感光到聚集之光，基於在該感光元件中之感光之光量等，偵測流入到偵測空間之煙霧而進行警報。於此，當組合如此之光電式煙霧感測器之際，首先，對被設置於偵測部本體之安裝用之機構（對應到發光元件及感光元件之形狀的孔部等）設定發光元件及感光元件且確定感光元件及發光元件之光軸，於此狀態下，將發光元件及感光元件之連接線（接腳）***到基板之貫通孔之後，於基板以焊接方式裝配連接線。Further, conventionally, a photoelectric smoke sensor (see, for example, Patent Document 5) is disclosed, which is disposed on a setting surface of a monitoring area, and detects smoke in the monitored area to perform an alarm. Such a conventional photoelectric smoke sensor generally has a light-emitting element, a light-sensing element, a photosensitive lens, a detection unit body and a smoke detecting portion. The light-emitting element allows the photosensitive lens to be concentrated based on detection. The scattered light in the smoke detecting portion of the light emitted by the detection space separated by the body and the smoke detecting portion causes the photosensitive member to sensitize the collected light, based on the amount of light in the photosensitive member, etc. The smoke flowing into the detection space is measured to alert. Herein, when such a photoelectric smoke sensor is combined, first, a light-emitting element is set to a mechanism (a hole portion corresponding to a shape of a light-emitting element and a light-receiving element) to be mounted on the main body of the detecting unit. The photosensitive element and the optical axis of the light-emitting element are determined. In this state, the connection line (pin) of the light-emitting element and the photosensitive element is inserted into the through-hole of the substrate, and the connection line is soldered to the substrate.

若對設置面螺固安裝板的話，安裝板之前面側，也就是說，於機器本體之安裝側會讓螺絲頭部露出。對安裝板安裝機器本體之際，若讓螺絲頭部碰到螺絲頭部的話，則可能會對機器本體造成損壞。譬如，於搭載有電池之機器本體中，藉由讓螺絲頭部衝撞到電池，則可能會損壞電池。另外，除此之外，螺絲頭部也有可能會損壞機器本體所具有之配線等。尤其係機器本體為薄型化情況下，由於在機器本體要縮小多餘之空間，所以從安裝板露出之螺絲頭部會增加對機器本體所帶來之影響。If the mounting surface is screwed to the mounting plate, the front side of the mounting plate, that is, the mounting side of the machine body will expose the screw head. When the machine body is attached to the mounting plate, if the screw head touches the screw head, it may cause damage to the machine body. For example, in a machine body equipped with a battery, the battery may be damaged by causing the screw head to collide with the battery. In addition, in addition to this, the screw head may damage the wiring of the machine body. In particular, in the case where the machine body is thinned, since the machine body is required to reduce the excess space, the screw head exposed from the mounting plate increases the influence on the machine body.

於火災警報器中，會要求來自揚聲器之聲音準位為既定以上。也就是說，揚聲器之音壓務必要既定以上，但隨著框體之小型化，也會限制可搭載之揚聲器之直徑。因此，期望就直接以此揚聲器之直徑就能發出更大音壓。In the fire alarm, the sound level from the speaker is required to be more than the predetermined. In other words, the sound pressure of the speaker must be more than the above, but as the frame is miniaturized, the diameter of the speaker that can be mounted is also limited. Therefore, it is desirable to directly emit a larger sound pressure by the diameter of the speaker.

為了易於操作操作鍵，期望著讓操作鍵為大型化。惟，若讓操作鍵為大型化，則用來作為按壓動作及回復到原本位置之動作的構造就變為更複雜，且也會增加操作鍵之零件數目或者讓操作鍵之形狀更加複雜化。由於操作鍵之複雜化，也會產生因為零件公差而導致讓按壓操作為誤動作。In order to facilitate the operation of the operation keys, it is desirable to make the operation keys large. However, if the operation key is increased in size, the structure for the action of pressing and returning to the original position becomes more complicated, and the number of parts of the operation key is increased or the shape of the operation key is further complicated. Due to the complication of the operation keys, the pressing operation is also caused to malfunction due to the tolerance of the parts.

對火災警報器會要求小型化。煙霧偵測部蓋體，為了改善遮光性，讓璧部形成為剖面略為V字狀，所以徑方向大小比較大，此也就成為妨礙到火災警報器之小型化的原因。另外，於火災警報器設置有用來發出聲音的揚聲器，於煙霧偵測部蓋體及框體之厚度方向中，若成為部分相互重疊該揚聲器之配置的話，由於可能無法從揚聲器獲得充分之音壓，所以必須作成不能讓兩者重疊之配置。隨著讓火災警報器小型化而縮小框體，要配置成不讓此等重疊係比較困難。Miniaturization is required for fire alarms. In order to improve the light-shielding property, the cover portion of the smoke detecting portion has a slightly V-shaped cross section, so that the radial direction is relatively large, which is a cause of hindering the miniaturization of the fire alarm. In addition, in the fire alarm device, a speaker for emitting sound is provided, and in the thickness direction of the cover portion of the smoke detecting portion and the frame body, if the arrangement of the speaker is partially overlapped, a sufficient sound pressure may not be obtained from the speaker. , so you must make a configuration that does not allow the two to overlap. As the fire alarm is miniaturized and the frame is reduced, it is difficult to arrange such overlapping.

然而，於上述如此之裝配方法上，由於必須對基板之通孔同時***發光元件及感光元件之連接線，所以讓***作業變為困難，且於裝配發光元件及感光元件時需耗費時間。另外，偵測本體，由於需要一用來安裝發光元件或感光元件之安裝用之機構，所以就讓偵測部本體之機構變為較複雜，此係較不希望者。However, in the above-described assembly method, since it is necessary to simultaneously insert the connection line of the light-emitting element and the photosensitive element to the through hole of the substrate, the insertion work becomes difficult, and it takes time to assemble the light-emitting element and the photosensitive element. In addition, since the detecting body requires a mechanism for mounting the light-emitting element or the photosensitive element, the mechanism of the detecting unit body is made more complicated, which is less desirable.

若藉由請求項35之警報裝置的話，以豎立於發光孔或感光孔周圍之方式來配置且由於具備用來覆蓋發光側偵測手段或感光側偵測手段周圍之遮光手段，所以可防止來自發光側偵測手段之光線不透過偵測空間就直接於感光偵測手段中被感光而導致偵測誤動作，同時也可防止讓堆積於覆蓋手段之塵埃，從覆蓋手段且透過發光孔或感光孔掉落到發光側偵測手段或感光側偵測手段而堆積於發光側偵測手段或感光側偵測手段之表面而降低偵測精密度之事情發生。If the alarm device of claim 35 is provided, it is arranged to stand around the light-emitting hole or the light-sensing hole, and is provided with a light-shielding means for covering the light-emitting side detecting means or the photosensitive side detecting means, thereby preventing from coming from The light of the light-emitting side detecting means is directly exposed to the light-sensing detecting means to detect the malfunction, and also prevents the dust accumulated in the covering means from the covering means and through the light-emitting hole or the photosensitive hole. Falling to the light-emitting side detecting means or the photosensitive side detecting means and depositing on the surface of the light-emitting side detecting means or the photosensitive side detecting means reduces the detection precision.

若藉由請求項36之警報裝置之製造方法的話，由於對基板安裝偵測手段且電氣性裝配之後設置有覆蓋手段，所以可省略一作業，該作業係從於覆蓋手段設定所有之偵測手段以後，讓基板覆蓋於覆蓋手段且於基板之通孔中同時***各偵測手段之連接線，且可讓偵測手段之裝配作業為簡單化，同時也不需於覆蓋手段中設置用來安裝偵測手段之機構，讓偵測手段之機構為簡單化且可提高警報裝置之生產性。According to the manufacturing method of the alarm device of claim 36, since the detecting means is mounted on the substrate and the covering means is provided after the electrical assembly, a job can be omitted, and the operation is to set all the detecting means from the covering means.

[實施形態1] 以下，將沿著圖面詳細說明本發明之實施形態1。於本實施形態1上，係以讓安裝於設置面之機器作為火災警報器來加以說明。第1圖係表示從於本實施形態1中之火災警報器所看到之立體圖，第2圖為表示從火災警報器背面側看到之立體圖。本實施形態1之火災警報器，係具有：可偵測發生火災且發出警報之警報器本體1；及對設置面安裝有警報器本體1之安裝板2。[Embodiment 1] Hereinafter, Embodiment 1 of the present invention will be described in detail along the drawings. In the first embodiment, the device attached to the installation surface is described as a fire alarm. Fig. 1 is a perspective view of the fire alarm device according to the first embodiment, and Fig. 2 is a perspective view of the fire alarm device. The fire alarm device according to the first embodiment includes an alarm body 1 that detects a fire and emits an alarm, and a mounting plate 2 on which the alarm body 1 is attached to the installation surface.

警報器本體1，具有一框體10，該框體10係於內部具有用來偵測煙霧之感應器等。於框體10之側面部，具有煙霧流入口12，從該煙霧流入口12將煙霧導引到框體10之內部，且藉由感應器來偵測煙霧。The alarm body 1 has a frame 10 which is internally provided with a sensor for detecting smoke and the like. At the side of the frame 10, there is a smoke inflow opening 12 from which the smoke is guided into the interior of the frame 10, and the smoke is detected by the sensor.

框體10，具有一面對室內側之前面11，於前面11設置有：用來進行各種操作之操作鍵13；及用來發出來自設置於框體10內部之揚聲器之聲音的聲音孔14。The casing 10 has a front surface 11 facing the indoor side, and the front surface 11 is provided with operation keys 13 for performing various operations, and sound holes 14 for emitting sound from a speaker provided inside the casing 10.

安裝板2，係設置於警報器本體1之背面側且可固定警報器本體1。固定有安裝板2之設置面，於本實施形態1上係為住宅之牆壁面。安裝板2對著垂直面之設置面且固定後，就對著安裝板2安裝固定警報器本體1。The mounting plate 2 is disposed on the back side of the alarm body 1 and can fix the alarm body 1. In the first embodiment, the installation surface of the mounting plate 2 is fixed to the wall surface of the house. After the mounting plate 2 faces the setting surface of the vertical surface and is fixed, the alarm body 1 is attached to the mounting plate 2.

安裝板2，具有一警報器固定面部20，該警報器固定面部20係被形成為於中央部具有孔且略為環狀。覦警報器固定面部20之上端部，形成有上面突出部21。上面突出部21雖係用於掛於事先設置面之場所之情況下，但是並不用於本實施形態1。於上面突出部21之根底部，形成有凹溝狀之切口，若不使用上面突出部21時，則可簡單地將此折疊起來而除去不用。The mounting plate 2 has an alarm fixing surface 20 which is formed to have a hole in the center portion and is slightly annular. The upper portion of the upper surface portion 20 of the alarm surface is fixed, and the upper protruding portion 21 is formed. The upper protruding portion 21 is used for hanging in a place where the surface is previously placed, but is not used in the first embodiment. A groove-shaped slit is formed at the bottom of the upper projection portion 21, and if the upper projection portion 21 is not used, it can be simply folded and removed.

第3圖為表示警報器本體1之背面圖。於警報器本體1之背面，於上面形成有電池收納部16，於該內部收納有電池17。電池收納部16，係形成為往背面側開口之凹狀，且該開口並未被封口。藉此，可讓框體10之蓋體厚度部分為薄型化。另外，於警報器本體1之背面，於圓周方向3處形成有安裝板固定部15。安裝板固定部15，係對著安裝板2且以可旋轉卡固之方式來形成。Fig. 3 is a rear view showing the alarm body 1. A battery housing portion 16 is formed on the back surface of the alarm body 1, and a battery 17 is housed therein. The battery housing portion 16 is formed in a concave shape that is open to the back side, and the opening is not sealed. Thereby, the thickness of the cover body of the casing 10 can be made thinner. Further, on the back surface of the alarm body 1, a mounting plate fixing portion 15 is formed in the circumferential direction 3. The mounting plate fixing portion 15 is formed to face the mounting plate 2 and is rotatably locked.

以下將更詳細說明安裝板2之構造。第4圖為表示安裝板2之前視圖。於安裝板2之警報器固定面部20，沿著圓周方向且於3處讓卡固片部24形成為爪狀。卡固片部24，係被形成於對應到形成於警報器本體1之背面部的安裝板固定部15的位置上，進而可讓此轉旋轉卡固。The configuration of the mounting board 2 will be described in more detail below. Figure 4 is a front view showing the mounting plate 2. In the alarm fixing surface portion 20 of the mounting plate 2, the locking piece portion 24 is formed in a claw shape along the circumferential direction and at three places. The locking piece portion 24 is formed at a position corresponding to the mounting plate fixing portion 15 formed on the back surface portion of the alarm body 1, and can be rotated and locked.

另外，於警報器固定面部20，設置複數個螺孔部22，此等該螺孔部22，係可對設置面讓用來固定安裝板2之螺絲揷通。於本實施形態1上，於複數之螺孔部22當中，由於使用位於上部12時方向的螺孔部22，所以以下將說明該螺孔部22。Further, a plurality of screw holes 22 are provided in the alarm fixing surface portion 20, and the screw holes 22 can be used to fix the screws for fixing the mounting plate 2 to the installation surface. In the first embodiment, the screw hole portion 22 in the direction of the upper portion 12 is used in the plurality of screw holes 22, and therefore the screw hole portion 22 will be described below.

螺孔部22，下部具有較大之直徑，上部具有較小之直徑，且具有讓此等為連續之葫蘆狀。於螺孔部22周圍，以圍繞此之方式，從警報器固定面部20形成有豎立之豎立部23。豎立部23，係形成為正面視之略為橢圓狀。The screw hole portion 22 has a larger diameter at the lower portion, a smaller diameter at the upper portion, and has a continuous gourd shape. Around the screw hole portion 22, an upright standing portion 23 is formed from the alarm fixing surface portion 20 in such a manner as to surround it. The standing portion 23 is formed in a slightly elliptical shape in a front view.

第5圖為表示緊固於設置面之螺絲30及安裝板20之立體圖。螺絲30，係對著事先設置面且緊固至某程度之位置。此時，螺絲30之頭部31，係形成為從設置面懸浮之狀態。Fig. 5 is a perspective view showing the screw 30 and the mounting plate 20 fastened to the installation surface. The screw 30 is placed in a position facing the front surface and fastened to a certain extent. At this time, the head portion 31 of the screw 30 is formed in a state of being suspended from the installation surface.

安裝板2之螺孔部22，係形成於可讓下部大直徑不揷通螺絲30之頭部31之直徑。因此，於螺孔部22之下部可讓螺絲30插通，且可成為讓螺絲30貫通到安裝板2之前面側之狀態。從該狀態來看，利用於下方來滑動安裝板2，而讓螺絲30位於螺孔部22上部之小直徑部分。螺孔部22之小直徑部分，由於係大於螺絲30之直徑且小於頭部31之直徑，所以利用讓螺絲30位於螺孔部22之小直徑部分，且藉由進一步緊固螺絲30，而讓螺絲30之頭部31壓接到螺孔部22之邊緣部，藉由螺絲30將安裝板2固定於設置面。The screw hole portion 22 of the mounting plate 2 is formed in a diameter that allows the lower portion of the large diameter to pass through the head 31 of the screw 30. Therefore, the screw 30 can be inserted into the lower portion of the screw hole portion 22, and the screw 30 can be inserted into the front surface side of the mounting plate 2. From this state, the mounting plate 2 is slid by the lower portion, and the screw 30 is placed at the small diameter portion of the upper portion of the screw hole portion 22. Since the small diameter portion of the screw hole portion 22 is larger than the diameter of the screw 30 and smaller than the diameter of the head portion 31, the screw 30 is placed in the small diameter portion of the screw hole portion 22, and the screw 30 is further tightened. The head portion 31 of the screw 30 is crimped to the edge portion of the screw hole portion 22, and the mounting plate 2 is fixed to the installation surface by the screw 30.

此時，讓螺絲30之頭部31，直到周圍沒有比豎立部23較突起之位置上，緊固螺絲30。也就是說，若從側方看安裝板1之情況下，直到頭部31完全地被豎立部23給掩蓋之前，緊固螺絲30。如此一來，豎立部23，也可利用讓緊固螺絲30之深度來作為刻度。At this time, the head 31 of the screw 30 is allowed to fasten the screw 30 until the periphery is not protruded from the standing portion 23. That is, if the mounting plate 1 is viewed from the side, the screw 30 is tightened until the head 31 is completely covered by the standing portion 23. In this way, the standing portion 23 can also be made to have the depth of the fastening screw 30 as a scale.

第6圖為表示火災警報器之縱向剖面圖。於該圖，也顯示螺絲30。於藉由螺絲30而將安裝板2固定於設置面之狀態中，螺絲30之頭部31，係無超過形成於螺孔部22周圍之豎立部23之高度。也就是說，螺絲30之頭部31相較於豎立部23來說，以不突出於正面側之方式，設定豎立部23之高度。Fig. 6 is a longitudinal sectional view showing a fire alarm. In the figure, the screw 30 is also shown. In the state in which the mounting plate 2 is fixed to the installation surface by the screw 30, the head portion 31 of the screw 30 does not exceed the height of the standing portion 23 formed around the screw hole portion 22. That is, the head portion 31 of the screw 30 sets the height of the standing portion 23 so as not to protrude from the front side as compared with the standing portion 23.

用來固定螺絲30之螺孔部22，係位於安裝板之上部，且係讓被收納於警報器本體1之電池收納部16的電池17及螺絲30之頭部31為對向。於此，於螺絲30之頭部31周圍，由於形成有沒有讓該頭部31突出之高度的豎立部23，所以不會讓電池17抵接到螺絲30之頭部31。也就是說，可讓從安裝板2往正面側顯露出之螺絲30之頭部31不會影響到警報器本體1。The screw hole portion 22 for fixing the screw 30 is located above the mounting plate, and the battery 17 and the head 31 of the screw 30 housed in the battery housing portion 16 of the alarm body 1 are opposed to each other. Here, the battery portion 17 is not abutted against the head portion 31 of the screw 30 because the standing portion 23 having the height at which the head portion 31 protrudes is formed around the head portion 31 of the screw 30. That is, the head 31 of the screw 30 which is exposed from the mounting plate 2 to the front side can be prevented from affecting the alarm body 1.

以上，雖係說明本發明之實施形態1，但是本發明之適用並非限定於本實施形態1，只要於該技術思想之範圍內皆可廣泛地被適用。譬如，於本實施形態1上，雖然豎立部23之高度係略與螺絲30之頭部31之突起高度相同，但是由只要豎立部23高過頭部31之突起高度即可，所以也可藉由不干擾到警報器本體1之程度而形成為較高。另外，於本實施形態1上並無限制形成螺孔部22及豎立部23之位置及數量，也可因應必要而適當地配置。再者，於本實施形態1中，設置面雖為一牆壁面，但是也可為天花板。另外，於本實施形態1中，機器雖為火災警報器，但是也可為氣體警報器，或其他種類之機器。Although the first embodiment of the present invention has been described above, the application of the present invention is not limited to the first embodiment, and can be widely applied within the scope of the technical idea. For example, in the first embodiment, although the height of the standing portion 23 is slightly the same as the height of the protrusion of the head portion 31 of the screw 30, the height of the protrusion of the head portion 31 may be higher than that of the head portion 31, so that it is also possible It is formed to be higher without interfering with the alarm body 1. Further, in the first embodiment, the position and the number of the screw holes 22 and the standing portions 23 are not limited, and may be appropriately arranged as necessary. Further, in the first embodiment, the installation surface is a wall surface, but it may be a ceiling. Further, in the first embodiment, the device is a fire alarm, but may be a gas alarm or another type of machine.

[實施形態2] 其次，沿著圖面詳細說明本發明之實施形態2-1~2-3。於本實施形態2-1~2-3上，係以火災警報器作為警報器來說明。第7圖為表示於本實施形態2-1當中之火災警報器之前視圖。本實施形態2-1之火災警報器，係具有一可偵測發生火災雸發出警報之警報器本體201。[Embodiment 2] Next, Embodiments 2-1 to 2-3 of the present invention will be described in detail along the drawings. In the present embodiment 2-1 to 2-3, a fire alarm is used as an alarm. Fig. 7 is a front view showing the fire alarm in the second embodiment. The fire alarm of the embodiment 2-1 has an alarm body 201 that can detect an alarm that a fire has occurred.

警報器本體201，具有一框體210，該框體210係於內部具有偵測煙霧之感應器。框體210，於側面部具有一煙霧流入口，可從該煙霧流入口將煙霧導引到框體210內部，且藉由內部感應器來偵測煙霧。The alarm body 201 has a frame 210 that is internally provided with a sensor for detecting smoke. The frame body 210 has a smoke inflow port at the side portion, and the smoke can be guided from the smoke inflow port to the inside of the frame body 210, and the smoke is detected by an internal sensor.

框體210，具有一面對室內側之前面部211，於前面部211設置有：用來進行各種操作之操作鍵214；及用來發出從設置於框體210內部之揚聲器217之聲音之聲音孔215。The housing 210 has a front side facing surface 211, and the front portion 211 is provided with operation keys 214 for performing various operations, and sound holes for emitting sound from the speaker 217 disposed inside the housing 210. 215.

第8圖為表示第7圖A-A所示之剖面圖。於警報器本體201之背面，於上部形成有電池收納部218。於該內部收納有電池219。電池收納部218，係形成為往背面側承開口之凹狀，且該開口並未被封口。藉此，可讓框體210之蓋體厚度部分為薄型化。Figure 8 is a cross-sectional view showing the A-A of Figure 7; A battery housing portion 218 is formed on the upper surface of the alarm body 201. A battery 219 is housed inside the battery. The battery housing portion 218 is formed in a concave shape that is open to the back side, and the opening is not sealed. Thereby, the thickness of the cover body of the casing 210 can be made thinner.

於框體210內部，配置有基板部216，且於基板部216，設置有用來偵測從煙霧流入口流入之煙霧的煙霧偵測部216。另外，第8圖雖未圖示，但是於基板部216安裝固定有揚聲器217。Inside the casing 210, a substrate portion 216 is disposed, and the substrate portion 216 is provided with a smoke detecting portion 216 for detecting smoke flowing in from the smoke inflow port. In addition, although not shown in FIG. 8, the speaker 217 is attached and fixed to the board|substrate part 216.

第9圖為表示第7圖B-B所示之剖面圖。如該圖所示，於形成於框體210內部之中空部分中，基板部216，係配置於厚度方向略為中央位置，被固定於基板部216之揚聲器217之正面217a，係與聲音孔215為對向。另外，於基板部216之背面側中，於基板部216及框體210之間，形成有空間部。於框體210之後面部212當中，形成該空間部之區域，係不具有孔等來堵塞。Figure 9 is a cross-sectional view showing the B-B of Figure 7; As shown in the figure, in the hollow portion formed inside the casing 210, the substrate portion 216 is disposed at a substantially central position in the thickness direction, and is fixed to the front surface 217a of the speaker 217 of the substrate portion 216, and the sound hole 215 is Opposite. Further, on the back side of the substrate portion 216, a space portion is formed between the substrate portion 216 and the housing 210. In the face portion 212 after the frame 210, the region in which the space portion is formed is not blocked by a hole or the like.

第10圖為表示基板部216之前視圖。如該圖所示，基板部216，具有部分為缺口之略圓形狀，於中央部，配置有用來偵測煙霧之感應器216b。基板部216，於周圍部形成揚聲器固定部220，揚聲器217被固定於此。Fig. 10 is a front view showing the substrate portion 216. As shown in the figure, the substrate portion 216 has a substantially circular shape with a portion being notched, and a sensor 216b for detecting smoke is disposed at the center portion. The board portion 216 has a speaker fixing portion 220 formed in the peripheral portion, and the speaker 217 is fixed thereto.

揚聲器固定部220，具有部分為缺口之略圓形狀之豎立部221，於豎立部221之內側，可配置有揚聲器217。豎立部221之內側，構成部分之基板部216且形成與揚聲器2217之背面為對向之基面部222，於基面部222，形成有由複數個小孔所形成貫通部226。The speaker fixing portion 220 has an upright portion 221 having a substantially circular shape with a notch, and a speaker 217 is disposed inside the standing portion 221 . Inside the standing portion 221, a portion of the substrate portion 216 is formed to form a base surface portion 222 opposite to the back surface of the speaker 2217, and a penetration portion 226 formed by a plurality of small holes is formed in the base surface portion 222.

於揚聲器固定部220之一側，設置有略T字狀之固定卡合片部223。固定卡合片部223，係與基板部216為一體，且無法對基板部216移動。另外，於與揚聲器固定部220之固定卡合片部223為對向之一側，設置有可對基板部216往既定方向移動之移動卡固片部224。固定卡合片部223及移動卡固片部224，係於固定在揚聲器固定部2220之揚聲器217之徑向中，以相互對向之方式來配置。A fixed engagement piece portion 223 having a substantially T-shape is provided on one side of the speaker fixing portion 220. The fixed engagement piece portion 223 is integral with the substrate portion 216 and cannot move the substrate portion 216. Further, on one side opposite to the fixed engagement piece portion 223 of the speaker fixing portion 220, a movement fixing piece portion 224 that can move the substrate portion 216 in a predetermined direction is provided. The fixed engagement piece portion 223 and the movable engagement piece portion 224 are disposed in the radial direction of the speaker 217 fixed to the speaker fixing portion 2220, and are disposed to face each other.

移動卡固片部224，係被形成於彈片225之前端部，該彈片225之前端部係於基面部216上被支撐為懸臂狀.。彈片225，係於基面部222外圍部，被支撐為懸臂狀，藉此，彈片225係可對基板部216，往該厚度方向進行彈性變形。藉此，移動卡固片部224，可對基板部216往該厚度方向移動。The moving card fixing portion 224 is formed at a front end portion of the elastic piece 225, and the front end portion of the elastic piece 225 is supported on the base surface portion 216 to be supported in a cantilever shape. The elastic piece 225 is attached to the outer peripheral portion of the base surface portion 222 and supported in a cantilever shape, whereby the elastic piece 225 can elastically deform the substrate portion 216 in the thickness direction. Thereby, the card fixing portion 224 can move the substrate portion 216 in the thickness direction.

第11圖為表示安裝有揚聲器217之基板部216之前視圖，第12圖為表示第11圖A-A所示之剖面圖。揚聲器217，具有略為圓狀之揚聲器本體217c，且於揚聲器本體217c之外圍，於徑向中，具有對向之一對的耳部217d。於耳部217d，形成有讓固定卡合片部223或移動卡固片部224卡固之卡固凹部217e。Fig. 11 is a front view showing the substrate portion 216 on which the speaker 217 is attached, and Fig. 12 is a cross-sectional view showing Fig. 11A-A. The speaker 217 has a substantially circular speaker body 217c, and has a pair of opposite ear portions 217d in the radial direction around the speaker body 217c. A locking recess 217e is formed in the ear portion 217d to secure the fixed engaging piece portion 223 or the moving locking piece portion 224.

當將揚聲器217安裝於揚聲器固定部220之際，首先，於從基面部222讓其中一方之耳部217d側懸浮之狀態下，讓形成於揚聲器217之另一方之耳部217d的卡固凹部217e對著固定卡合片部223來卡固。之後，若其中一方之耳部217d側抵觸壓接到移動卡固片部224的話，則會讓彈片225彈性變形，而讓移動卡固片部224對另一方之耳部217d來卡固。藉此，於與徑向為對向之2處，對揚聲器固定部220來卡固揚聲器217，且可牢固地將揚聲器217固定於基板部216。When the speaker 217 is attached to the speaker fixing portion 220, first, the locking recess 217e formed in the other ear portion 217d of the speaker 217 is suspended in a state in which one of the base portions 222 is suspended from the base portion 222d. The fixing engagement piece portion 223 is engaged to be engaged. Thereafter, if one of the ear portions 217d is pressed against the movable locking piece portion 224, the elastic piece 225 is elastically deformed, and the moving locking piece portion 224 is locked to the other ear portion 217d. Thereby, the speaker 217 is affixed to the speaker fixing portion 220 at two places opposed to the radial direction, and the speaker 217 can be firmly fixed to the substrate portion 216.

於徑向中且於對向之耳部217d之中，由於對基板部216可彈性地來卡固揚聲器217，所以可抑制因溫度或溼度等之環境變化而讓揚聲器217之固態狀態產生變化。另外，揚聲器217，雖可藉由固定卡合片部223及移動卡固片部224，以挾持之方式來卡固，但是卡固位置，另外，揚聲器217，雖係藉由固定卡合片部223及移動卡固片部224且以挾持之方式來卡固，但是卡固位置，由於係從揚聲器217之外圍而形成為突起狀之耳部217d，所以可防止揚聲器本體217c之變形且可防止音壓之降低。In the radial direction and in the opposing ear portion 217d, since the speaker portion 217 can be elastically locked to the substrate portion 216, it is possible to suppress a change in the solid state of the speaker 217 due to environmental changes such as temperature or humidity. Further, the speaker 217 can be clamped by the fixed engaging piece portion 223 and the moving locking piece portion 224, but the fixing position and the speaker 217 are fixed by the engaging piece portion. 223 and the moving card fixing portion 224 are clamped in a manner of holding, but the locking position is formed as a protruding ear portion 217d from the periphery of the speaker 217, so that the deformation of the speaker body 217c can be prevented and prevented The sound pressure is reduced.

如第9圖所示，揚聲器217，係讓振動而發出聲音之正面217a，面向基板部216之正面側，背面217b係與基面部222為對向。基面部222，由於係形成有小孔狀之貫通部226，所以揚聲器217之背面217b，係透過貫通部226且面向於形成在基板部216及框體210之後面部212之間的空間部。As shown in Fig. 9, the speaker 217 is a front surface 217a that emits a sound by vibration, faces the front side of the substrate portion 216, and the back surface 217b faces the base surface portion 222. Since the base surface portion 222 is formed with a small hole-shaped penetration portion 226, the back surface 217b of the speaker 217 passes through the penetration portion 226 and faces the space portion formed between the substrate portion 216 and the rear surface portion 212 of the housing 210.

當揚聲器217發出聲音之際，會讓正面217a側振動且發出聲音，該聲音透過框體210之聲音孔215而傳送到外部。另外，揚聲器217之正面217a側之振動，也往揚聲器217整體來擴廣，因此，聲音也傳送到揚聲器217之背面217b側。該聲音，係透過被形成於基面部222之貫通部226而於框體210之後面部212側之空間部產生共鳴且傳送到外部。When the speaker 217 emits a sound, the front side 217a side vibrates and a sound is emitted, and the sound is transmitted to the outside through the sound hole 215 of the casing 210. Further, since the vibration on the front side 217a side of the speaker 217 is also expanded toward the entire speaker 217, the sound is also transmitted to the side of the rear surface 217b of the speaker 217. This sound is resonated in the space portion on the side of the face portion 212 after the casing 210 through the penetration portion 226 formed in the base surface portion 222, and is transmitted to the outside.

於揚聲器217之背面217b側讓聲音共鳴之效果，會因為揚聲器217之直徑或框體210之後面部212側之空間部之容積或形狀或貫通部226之面積等而有所不同。於本實施形態2－1上，貫通部226係藉由複數個小孔而形成，所以以讓共鳴效果達到最大之方式，可調整貫通部226之面積。The effect of resonating the sound on the side of the back surface 217b of the speaker 217 differs depending on the diameter of the speaker 217 or the volume or shape of the space portion on the side of the face portion 212 after the frame 210 or the area of the penetration portion 226. In the second embodiment, the penetration portion 226 is formed by a plurality of small holes, so that the area of the penetration portion 226 can be adjusted so that the resonance effect is maximized.

具體而言，於基面部222事先較多形成預先小孔，且於組裝所有火災警報器之零件之狀態下，從揚聲器217發出聲音且測定該聲音。其次，以樹脂等堵塞被形成於基面部222之部分小孔，再從揚聲器217發生聲音測定音壓。反覆此步驟，讓聲壓最高的小孔數目設定為於實際製品中之小孔數目。於製造實際產品之際，對基板部216，讓預先所形成之小孔當中之一部分，以成為被設定之小孔數目之方式，外加堵塞步驟。藉此，即可製造出來自揚聲器217之音壓為最大之火災警報器。小孔之數目的調整，可個別進行調整或設定於每個製造批號。又，也可不進行該調整而藉由所有相同數目之小孔來形成貫通部226。Specifically, in the base surface portion 222, a small number of small holes are formed in advance, and in a state in which all the components of the fire alarm are assembled, sound is emitted from the speaker 217 and the sound is measured. Next, a small hole formed in the base surface portion 222 is blocked by a resin or the like, and a sound measurement sound pressure is generated from the speaker 217. Repeat this step to set the number of small holes with the highest sound pressure as the number of small holes in the actual product. When the actual product is manufactured, the substrate portion 216 is subjected to a clogging step in such a manner that one of the small holes formed in advance is the number of small holes to be set. Thereby, the fire alarm from the speaker 217 having the highest sound pressure can be manufactured. The adjustment of the number of small holes can be individually adjusted or set to each manufacturing lot number. Further, the through portion 226 may be formed by all the same number of small holes without performing the adjustment.

如此一來，於與揚聲器217之背面217b為對向之基面部222，可利用形成貫通部226，而該貫通部226係與被形成於基板部216及框體210之後面部212之間的空間部連通，增加來自揚聲器217之音壓。也就是說，即使縮小揚聲器217之直徑，由於可達成既定之音壓，所以可讓框體210為小型化。In this manner, the base portion 222 opposite to the back surface 217b of the speaker 217 can be formed with a through portion 226 which is formed between the substrate portion 216 and the face portion 212 after the frame 210. The parts are connected to increase the sound pressure from the speaker 217. That is, even if the diameter of the speaker 217 is reduced, since the predetermined sound pressure can be achieved, the frame 210 can be made compact.

另外，利用讓貫通部226藉由小孔來形成，且藉由調整小孔之數目，可讓揚聲器217之音壓為最大化，同時因為為小孔，所以也可防止讓昆蟲等侵入到煙霧偵測部216a側。In addition, by making the through portion 226 formed by the small hole, and by adjusting the number of the small holes, the sound pressure of the speaker 217 can be maximized, and at the same time, because it is a small hole, insects and the like can be prevented from intruding into the smoke. The detecting unit 216a side.

其次，說明本發明之實施形態2－2。第13圖為表示用於實施形態2-2之火災警報器之基板部230之前視圖。本實施形態2－2，其中，由於設置於基板部230之揚聲器固定部231以外之構造係與實施形態2－1為共同，所以僅說明揚聲器固定部231。Next, an embodiment 2-2 of the present invention will be described. Fig. 13 is a front elevational view showing the substrate portion 230 used in the fire alarm of the embodiment 2-2. In the second embodiment, the structure other than the speaker fixing portion 231 of the substrate portion 230 is the same as that of the embodiment 2-1. Therefore, only the speaker fixing portion 231 will be described.

揚聲器固定部231，於外圍部具有從基板部230豎立之豎立部232，且該內側之區域，係為構成部分之基板部230之基面部233。於基面部233之一側，形成有固定卡合片部234。於與形成有基面部233之固定卡合片部234側為相反側，形成有2個細縫部237，且該2個細縫部237係從端部到達超過基面部233中央之位置。2個細縫部237，係以相互平行之方式形成，且以具有各直徑為不同之弧狀部分之方式來形成。藉此，於基面部233，形成有一彈片236，該彈片236係可往基板部230之厚度方向彈性變形。The speaker fixing portion 231 has an upright portion 232 that is erected from the substrate portion 230 at the outer peripheral portion, and the inner portion is a base portion 233 of the substrate portion 230 that constitutes a portion. A fixed engaging piece portion 234 is formed on one side of the base surface portion 233. Two slit portions 237 are formed on the side opposite to the side of the fixed engagement piece portion 234 on which the base surface portion 233 is formed, and the two slit portions 237 are located from the end portion to a position beyond the center of the base surface portion 233. The two slit portions 237 are formed to be parallel to each other, and are formed to have arcuate portions having different diameters. Thereby, an elastic piece 236 is formed on the base surface portion 233, and the elastic piece 236 is elastically deformable in the thickness direction of the substrate portion 230.

於彈片236之前端部，以與固定卡合片部234及揚聲器217之直徑方向中為對向之方式，形成有移動卡固片部235。本實施形態2－2之彈片236，於基板部30被支撐為懸臂狀之特徵上，雖係與實施形態2－1相同，但是利用讓形成彈片236之細縫部237，從其中一端部到達超越基面部233中央之位置，係比起實施形態2－1之情況來說，彈片236之變形量較大。因此，於揚聲器固定部231安裝揚聲器217之際，係易於讓揚聲器固定部231卡固到揚聲器217之卡固凹部217e，且易於讓安裝作業容易化。A moving locking piece portion 235 is formed at an end portion of the elastic piece 236 so as to oppose the diametrical direction of the fixed engaging piece portion 234 and the speaker 217. The elastic piece 236 of the embodiment 2-2 is similar to the embodiment 2-1 in that the substrate portion 30 is supported in a cantilever shape, but the sipe portion 237 that forms the elastic piece 236 is used to reach the end from one end portion thereof. The position of the center of the base portion 233 is larger than that of the embodiment 2-1, and the amount of deformation of the elastic piece 236 is large. Therefore, when the speaker 217 is attached to the speaker fixing portion 231, the speaker fixing portion 231 is easily caught in the locking recess 217e of the speaker 217, and the mounting work can be easily facilitated.

另外，形成於基面部233之細縫部237，其功能也可作為讓形成於揚聲器217之背面217b及框體210之後面部212側之空間部連通之貫通部。因此，也可讓增加來自揚聲器217之音壓的效果，達到與實施形態2－1相同之效果。Further, the slit portion 237 formed in the base portion 233 functions as a penetration portion that allows the space portion formed on the side surface 212 side of the speaker 217 and the rear surface 217b of the housing 210 to communicate with each other. Therefore, the effect of the sound pressure from the speaker 217 can be increased to achieve the same effect as that of the embodiment 2-1.

其次，說明本發明之實施形態2－3。第14圖為表示用於實施形態2-3之火災警報器之基板部240之前視圖。本實施形態2－3，其中，由於設置於基板部240之揚聲器固定部241以外之構造係與實施形態2－1為共同，所以僅說明揚聲器固定部241。Next, an embodiment 2-3 of the present invention will be described. Fig. 14 is a front elevational view showing the substrate portion 240 of the fire alarm device of the embodiment 2-3. In the second embodiment, the structure other than the speaker fixing portion 241 of the substrate portion 240 is the same as that of the embodiment 2-1. Therefore, only the speaker fixing portion 241 will be described.

揚聲器固定部241，係於外圍部具有從基板部240豎立之豎立部242，且該內側之區域，係為構成部分之基板部240之基面部243。於基面部243之一側，形成有固定卡合片部244。於與形成有基面部243之固定卡合片部244側為相反側，形成有移動卡固片部245。移動卡固片部245，係形成為島狀部246，該島狀部係於小直徑之橋接部247連接與基板部240之間所形成。The speaker fixing portion 241 has an upright portion 242 that is erected from the substrate portion 240 at the outer peripheral portion, and the inner portion is a base portion 243 of the substrate portion 240 that constitutes a portion. A fixed engaging piece portion 244 is formed on one side of the base surface portion 243. A movement fixing piece portion 245 is formed on the side opposite to the side of the fixed engagement piece portion 244 on which the base surface portion 243 is formed. The moving card fixing portion 245 is formed as an island portion 246 which is formed between the small-diameter bridge portion 247 and the substrate portion 240.

島狀部246，由於係於小直徑之橋接部247且與基板部240連接，所以對基板部240，可往該平面方向，具體而言，係往從對向之固定卡合片部244離開之方向，可彈性地移動。當將揚聲器217固定到揚聲器固定部241之際，係讓對固定卡合片部244而卡固其中一方之卡固凹部217e之揚聲器217，利用藉由橋接部247之彈性變形讓島狀部246移動，可讓另一方之卡固凹部217e卡固到移動卡固片部245。Since the island portion 246 is attached to the bridge portion 247 having a small diameter and is connected to the substrate portion 240, the substrate portion 240 can be separated from the plane portion, specifically, the fixed engagement piece portion 244 from the opposite direction. The direction can be moved elastically. When the speaker 217 is fixed to the speaker fixing portion 241, the speaker 217 that secures one of the engaging recess portions 217e to the fixed engaging piece portion 244 is used to allow the island portion 246 to be elastically deformed by the bridge portion 247. Moving, the other of the locking recesses 217e can be locked to the moving card portion 245.

另外，於島狀部246及基板部240之間，形成有間隙部248。其中，被形成於島狀部246之基面部243中央位置側之間隙部248，由於係配置於基面部243內，所以其功能也可作為讓形成於揚聲器217之背面217b及框體210之後面部212側之空間部連通之貫通部。因此，也可讓增加來自揚聲器217之音壓的效果，達到與實施形態2－1相同之效果。Further, a gap portion 248 is formed between the island portion 246 and the substrate portion 240. The gap portion 248 formed on the central position side of the base portion 243 of the island portion 246 is disposed in the base portion 243, so that the function can be used as the face portion 217b and the frame 210 after the speaker 217 is formed. A through portion that communicates with the space portion on the 212 side. Therefore, the effect of the sound pressure from the speaker 217 can be increased to achieve the same effect as that of the embodiment 2-1.

以上，雖係說明本發明之實施形態2－1~2－3，但是本發明並非限定適用於本實施形態2－1~2－3，且於該技術思想範圍內皆可廣泛地被適用。譬如，於上述之實施形態2－1~2－3上，揚聲器固定部220，具有1個之固定卡合片部223及1個移動卡固片部224，雖讓此等配置為對向，但是也可讓3個以上之卡固片部配置於揚聲器217圓周方向之複數處。此種情況下，可將至少1個之卡固片部作為移動卡固片部，將該以外之卡固片部作為固定卡合片部。Although the embodiments 2-1 to 2-3 of the present invention have been described above, the present invention is not limited to the embodiments 2-1 to 2-3, and can be widely applied within the scope of the technical idea. For example, in the above-described embodiments 2-1 to 2-3, the speaker fixing portion 220 has one fixed engaging piece portion 223 and one moving locking piece portion 224, and these are arranged to face each other. However, three or more card fixing portions may be disposed at a plurality of positions in the circumferential direction of the speaker 217. In this case, at least one of the card securing portions can be used as the moving card securing portion, and the other securing portion can be used as the fixed engaging piece portion.

[實施形態3] 其次，沿著圖面詳細說明本發明之實施形態3。於本實施形態3上，係以讓警報器作為火災警報器來加以說明。第15圖為表示於本實施形態3當中之火災警報器之前視圖。本實施形態3之火災警報器，具有可偵測火災發生且發出警報之警報器本體301。[Embodiment 3] Next, Embodiment 3 of the present invention will be described in detail along the drawings. In the third embodiment, the alarm is described as a fire alarm. Fig. 15 is a front view showing the fire alarm in the third embodiment. The fire alarm of the third embodiment has an alarm body 301 that can detect the occurrence of a fire and issue an alarm.

警報器本體301，係具有一框體310，該框體310係於內部具有用來偵測煙霧之感應器等。框體310之側面部，具有煙霧流入口，從該煙霧流入口將煙霧導引到框體310之內部，且藉由感應器來偵測煙霧。The alarm body 301 has a frame 310 with an inductor or the like for detecting smoke inside. The side portion of the frame 310 has a smoke flow inlet from which the smoke is guided to the inside of the frame 310, and the smoke is detected by the sensor.

框體310，具有一面對室內側之前面311，於前面311設置有：用來進行各種操作之操作鍵313；及用來發出來自設置於框體310內部之揚聲器之聲音的聲音孔314。The housing 310 has a front side facing surface 311, and the front surface 311 is provided with operation keys 313 for performing various operations, and sound holes 314 for emitting sound from the speakers disposed inside the housing 310.

於開始使用火災警報器之際，利用最初按壓操作操作鍵313及可進行開啟電源。當電源開啟時，火災警報器就開始進行感應火災。另外，電源開啟之後，於平常正常中，利用按壓操作鍵313，即可進行感應之測試。於正常時之測試，也可進行電池沒電或更換時間訊息或揚聲器之斷線。再者，藉由感應器偵測火災，當發出警報之情況時，可利用按壓操作操作鍵313來停止警報。如此一來，操作鍵313，可因應狀況而於火災警報器進行以1個按壓操作而不同之動作。When the fire alarm is started, the operation key 313 is initially pressed and the power can be turned on. When the power is turned on, the fire alarm starts to sense the fire. In addition, after the power is turned on, the sensing test can be performed by pressing the operation key 313 in normal normal operation. In the normal test, the battery can be discharged or the time message or the speaker disconnection can be performed. Furthermore, the fire is detected by the sensor, and when an alarm is issued, the operation key 313 can be pressed to stop the alarm. In this way, the operation key 313 can be operated differently by one pressing operation in the fire alarm depending on the situation.

第16圖為表示第15圖A-A所示之剖面圖。如該圖所示，於警報器本體301之背面，於上部形成有電池收納部316，於該內部收納有電池317。電池收納部316，係形成為往背面側為開口之凹狀，且該開口並未被封口。藉此，可讓框體310之蓋體的厚度部分為薄型化。Figure 16 is a cross-sectional view showing the Fig. 15A-A. As shown in the figure, a battery housing portion 316 is formed on the upper surface of the alarm body 301, and a battery 317 is housed therein. The battery housing portion 316 is formed in a concave shape having an opening toward the back side, and the opening is not sealed. Thereby, the thickness of the lid body of the frame body 310 can be made thinner.

操作鍵313，具有一操作部320，該操作部320係從框體310之開口部310a顯露出來。操作部320，係與框體310之前面311形成大略齊平狀，以往框體310內面側按壓之方式，可操作該操作部320。於框體310內，以與操作鍵313之操作部320為對向之方式，配置有開關318，伴隨著按壓操作操作鍵313來按壓開關318。藉由按壓開關318，可讓火災警報器偵測出操作鍵313之按壓操作。The operation key 313 has an operation unit 320 that is exposed from the opening 310a of the casing 310. The operation unit 320 is formed in a substantially flush shape with the front surface 311 of the casing 310, and the operation unit 320 can be operated such that the inner surface of the casing 310 is pressed. In the casing 310, a switch 318 is disposed so as to oppose the operation portion 320 of the operation key 313, and the switch 318 is pressed by pressing the operation key 313. By pressing the switch 318, the fire alarm can be detected by the fire alarm.

以下，更詳細地說明操作鍵313之構造。第17圖為表示操作鍵313之前視圖，第18圖為表示操作鍵313之側面圖，第19圖為表示第17圖A-A所示之剖面圖，第20圖為表示從背面側看到操作鍵313之立體圖。操作鍵313，係具有：往上下方向且形成為較長之正面視之略橢圓狀之操作部320；從操作部320之一端部之下端部，以往下垂之2個為一對之外方延伸部321；於外方延伸部321間從操作部320下端部往下垂之彈片323；及從操作部320往背面側延伸之後方延伸部325。2個之外方延伸部321及後方延伸部325為一體化且形成往下方為開口之剖面略コ狀。Hereinafter, the configuration of the operation key 313 will be described in more detail. Fig. 17 is a front view showing the operation key 313, Fig. 18 is a side view showing the operation key 313, Fig. 19 is a sectional view showing the 17th figure AA, and Fig. 20 is a view showing the operation key from the back side. A perspective view of 313. The operation key 313 has an operation portion 320 that is slightly elliptical in a front view that is formed in a vertical direction, and has a pair of outwardly extending ones from the lower end portion of the end portion of the operation portion 320. a portion 321; an elastic piece 323 that hangs from the lower end portion of the operation portion 320 between the outer extending portions 321; and a rear extending portion 325 extending from the operation portion 320 toward the back side. Two outer extending portions 321 and rear extending portions 325 It is integrated and forms a section that is slightly open to the bottom.

於朝向外方延伸部321之外側面，形成各往側方突起之轉軸部322。轉軸部322，係對框體310之軸承部310b卡固為可旋轉。藉此，操作鍵313，即可以轉軸部322為中心且往向背面側傾斜之方向來旋轉。The shaft portion 322 of each of the lateral protrusions is formed on the outer side surface of the outer extension portion 321 . The rotation shaft portion 322 is configured to be rotatable with respect to the bearing portion 310b of the frame body 310. Thereby, the operation key 313 can be rotated in the direction in which the shaft portion 322 is centered and inclined toward the back side.

彈片323，如第19圖所示，形成為較薄之板狀，沿著操作部320之按壓方向可彈性變形。於彈片323之前端部，形成往正面側突起之卡固部324。卡固部324，如第16圖所示，對被形成於框體310之內面下端部附近之鎖扣部310c而卡固。於該卡固狀態中，彈片323係讓操作鍵313從按壓往復位之方向，也就是說，於警報器本體301之正面側形成略為施力之狀態。The elastic piece 323 is formed into a thin plate shape as shown in Fig. 19, and is elastically deformable in the pressing direction of the operation portion 320. At the front end of the elastic piece 323, a fixing portion 324 which protrudes toward the front side is formed. As shown in Fig. 16, the hook portion 324 is locked to the latch portion 310c formed near the lower end portion of the inner surface of the housing 310. In the stuck state, the elastic piece 323 causes the operation key 313 to be in a direction of pressing the reciprocating position, that is, a state in which a slight force is applied to the front side of the alarm body 301.

操作鍵313，於操作部320周圍，具有邊緣部328。另外，框體310，於開口部310a之邊緣部，具有段部310d，操作鍵313之邊緣部328，係對段部310d從背面側抵接。如前述所言，操作鍵313，係藉由彈片323，往警報器本體301之正面側施力，所以操作鍵313之邊緣部328，係對框體310之段部310d成壓接之狀態。藉此，可防止操作鍵313之搖晃或因為意外之力量所造成之脫落等現象發生。The operation key 313 has an edge portion 328 around the operation portion 320. Further, the casing 310 has a segment portion 310d at the edge portion of the opening portion 310a, and the edge portion 328 of the operation key 313 abuts against the segment portion 310d from the back side. As described above, the operation key 313 is biased toward the front side of the alarm body 301 by the elastic piece 323. Therefore, the edge portion 328 of the operation key 313 is in a state in which the segment portion 310d of the frame body 310 is crimped. Thereby, it is possible to prevent the operation key 313 from being shaken or the phenomenon of falling off due to an unexpected force.

彈片323，雖如此地往原本操作鍵313之復位方向來施力，但若按壓操作操作鍵313且以轉軸部322為中心而傾斜的話，會讓下端部之卡固部324對框體310來卡固，所以將以朝向背面側而扭曲之方式而彈性變形，且以更強大之力量讓操作鍵313往復位方向來施力。The elastic piece 323 is biased in the reset direction of the original operation key 313. However, if the operation key 313 is pressed and tilted about the rotation shaft portion 322, the fastening portion 324 of the lower end portion is brought to the frame 310. Since it is fastened, it is elastically deformed in such a manner as to be twisted toward the back side, and the force is applied to the reciprocating direction of the operation key 313 with a stronger force.

如第20圖所示，後方延伸部325，於後端附近形成有橫向之細縫部326。第21圖為表示從火災警報器之背面側看到之立體圖。如該圖所示，操作鍵313之後方延伸部325，係從框體310之背面側露出。As shown in Fig. 20, the rear extending portion 325 is formed with a lateral slit portion 326 near the rear end. Fig. 21 is a perspective view showing the back side of the fire alarm. As shown in the figure, the rear extension portion 325 of the operation key 313 is exposed from the back side of the casing 310.

第22圖為表示於第21圖中之後方延伸部附近之放大圖。於本圖上，係表示於後方延伸部325，安裝有拉繩330之狀態。於細縫部326，可揷通拉繩330之前端部。於拉繩330之前端部形成有一結（knot），細縫部326之寬度係以大於拉繩330之直徑且小於結之直徑之方式來設定。因此，於拉繩330之前端部事先形成有結。相較於拉繩330之結，係將前端側及相反側之部分***到細縫部326，且利用往下方拉引拉繩330，即可對操作鍵313簡單地來安裝拉繩330。安裝有拉繩330之細縫部326，由於係對轉軸部322而形成於後方之上方，藉由往下方拉引拉繩330，就能夠以轉軸部322為中心且往朝向背面側傾斜操作鍵313之方向來轉動。Fig. 22 is an enlarged view showing the vicinity of the rear extension portion in Fig. 21. In the figure, the state in which the drawstring 330 is attached to the rear extension portion 325 is shown. At the slit portion 326, the front end of the drawstring 330 can be passed. A knot is formed at the end of the drawstring 330, and the width of the slit portion 326 is set to be larger than the diameter of the drawstring 330 and smaller than the diameter of the knot. Therefore, a knot is formed in advance at the front end of the drawstring 330. The portion of the front end side and the opposite side is inserted into the slit portion 326 as compared with the knot of the pull cord 330, and the draw cord 330 can be simply attached to the operation key 313 by pulling the drawstring 330 downward. The slit portion 326 to which the drawstring 330 is attached is formed on the upper side of the shaft portion 322, and by pulling the drawstring 330 downward, the operation key 313 can be tilted toward the back side with the rotation shaft portion 322 as the center. The direction to turn.

細縫部326，係形成於後方延伸部325之後端附近，所以會縮小細縫部326及後方延伸部325之後端之間的部分之後端部325a之寬度。因此，後方延伸部325之後端部325a，係可往擴大細縫部326之寬度的方向來變形。Since the slit portion 326 is formed in the vicinity of the rear end of the rear extending portion 325, the width of the portion between the rear end portion 325a between the slit portion 326 and the rear end portion of the rear extending portion 325 is reduced. Therefore, the rear end portion 325a of the rear extending portion 325 can be deformed in a direction in which the width of the slit portion 326 is enlarged.

若對拉繩330施加較大之力量之情況且該力量就直接傳遞到操作鍵313的話，可能會破壞操作鍵313或框體310。利用讓細縫部326可往擴大寬度之方向來變形，若於拉繩330往下方施加較大力量時，會讓結壓住細縫部326而擴廣而脫落，所以對操作部盡量不要施加較大之力量。會讓拉繩330之結從細縫部326脫落之力道，雖可配合操作鍵313或框體310之強度來適當設置，但是於本實施形態3上，係設略為8~10kg。If a large force is applied to the drawstring 330 and the force is directly transmitted to the operation key 313, the operation key 313 or the frame 310 may be broken. When the slit portion 326 is deformed in the direction in which the width is widened, if a large force is applied downward to the drawstring 330, the joint is pressed against the slit portion 326 to expand and fall off, so that the operation portion should not be applied as much as possible. The power. The force which causes the knot of the drawstring 330 to fall off from the slit portion 326 can be appropriately set in accordance with the strength of the operation key 313 or the frame 310. However, in the third embodiment, it is slightly 8 to 10 kg.

第23圖為表示於第15圖B-B當中，框體310下部之放大圖。如該圖所示，於框體310之內部，形成有往上方開口且呈U字狀之軸承部310b，於該軸承部310b，收納有操作鍵313之轉軸部322且轉動自如。Fig. 23 is an enlarged view showing the lower portion of the casing 310 in Fig. 15B-B. As shown in the figure, a bearing portion 310b that is open upward and has a U-shape is formed inside the casing 310, and the shaft portion 322 of the operation key 313 is housed and rotatably accommodated in the bearing portion 310b.

第24圖為表示從第16圖之狀態，於按壓操作操作鍵313之狀態當中之框體310下部之放大剖面圖。操作鍵313，係以位於下方之轉軸部322為中心而轉動，所以如第24圖所示，若按壓操作操作部320的話，會讓操作部320上側往背面側傾斜，操作部320會按壓框體310內之開關318。此時，如前述所言，操作鍵313之彈片323，利用讓卡固部324卡固到框體310之鎖扣部310c，往操作鍵313之復位方向施力，但是從該狀，進一歩能以往操作鍵313之復位方向來施力之方式而彈性變形。因此，若手離開操作部320的話，即可讓操作鍵313回復到原本位置。又，於後方延伸部325安裝有拉繩330，若拉引該拉繩330之情況時，也同樣地會讓操作鍵313動作。Fig. 24 is an enlarged cross-sectional view showing the lower portion of the casing 310 in a state in which the operation key 313 is pressed from the state of Fig. 16. The operation key 313 is rotated about the lower shaft portion 322. Therefore, as shown in Fig. 24, when the operation portion 320 is pressed, the upper portion of the operation portion 320 is inclined toward the back side, and the operation portion 320 is pressed. Switch 318 in body 310. At this time, as described above, the elastic piece 323 of the operation key 313 is biased to the locking direction 310c of the housing 310 by the locking portion 324, and the force is applied to the reset direction of the operation key 313. It can be elastically deformed in such a manner that the pressing direction of the operation key 313 is applied in the past. Therefore, if the hand leaves the operation unit 320, the operation key 313 can be returned to the original position. Further, the pull cord 330 is attached to the rear extension portion 325, and when the pull cord 330 is pulled, the operation key 313 is similarly operated.

如此一來，藉由以具有軸承部310b之框體310；及整體為一體性且具有轉軸部322之操作鍵313而所構成按壓鍵之構造，既能以簡單之構造來進行按壓動作及復位動作。另外，由於零件數目少，所以也可抑制因零件公差所導致之按壓操作為誤動作。In this manner, by the structure in which the frame body 310 having the bearing portion 310b and the operation key 313 having the rotation shaft portion 322 as a whole are integrally formed, the pressing operation and the resetting can be performed with a simple structure. action. In addition, since the number of parts is small, it is possible to suppress the pressing operation due to the tolerance of the parts from being malfunctioning.

另外，成為操作鍵313之旋轉中心的轉軸部322，由於係藉由按壓操作之操作部320而形成於為下方之外方延伸部321，所以可充分確保操作部320之按壓深度。尤其操作部320，係呈往上下方向且長形而略為橢圓狀，所以可增加與轉軸部322之距離且可加深按壓深度。Further, since the rotation shaft portion 322 which is the rotation center of the operation key 313 is formed in the lower outer extension portion 321 by the operation portion 320 which is pressed, the pressing depth of the operation portion 320 can be sufficiently ensured. In particular, since the operation portion 320 is elongated in the vertical direction and slightly elliptical, the distance from the rotation shaft portion 322 can be increased and the depth of compression can be deepened.

另外，於操作鍵313下部，於前端部，形成具有卡固部324之彈片323，由於卡固部324係卡固於框體310，所以當按壓操作部320之際，會讓彈片323彈性變形，且由於往操作鍵313之復位方向施力，所以若手離開操作部320，即可讓操作鍵313進行復位動作。再者，彈片323，係於讓卡固部324卡固於框體310之狀態下，往操作鍵313之復位方向來施力，且操作鍵313，由於係讓邊緣部328從背面側抵接到框體310之段部310d，所以可防止讓操作鍵313搖混或者從框體310往外脫落之事情發生。Further, in the lower portion of the operation key 313, a spring piece 323 having a fastening portion 324 is formed at the front end portion, and since the fastening portion 324 is fastened to the frame body 310, when the operation portion 320 is pressed, the elastic piece 323 is elastically deformed. Since the force is applied to the reset direction of the operation key 313, if the hand is moved away from the operation unit 320, the operation key 313 can be reset. Further, the elastic piece 323 is biased in the reset direction of the operation key 313 while the fastening portion 324 is engaged with the frame 310, and the operation key 313 is brought into contact with the edge portion 328 from the back side. Since it is to the segment portion 310d of the casing 310, it is possible to prevent the operation key 313 from being mixed or detached from the casing 310.

以上，雖然係說明本發明之實施形態3，但是本發明之適用並非限制於本實施形態3，且於該技術思想之範圍內皆可廣泛地來適用。譬如，操作鍵31位於警報器本體301當中之位置或大小，形狀，並非限定於本實施形態3。於本實施形態3中，操作鍵313，雖往上下方向具有長條形狀，但是也可往左右方向具有長條形狀，或也可為圓形或四角形等皆可。另外，即使操作鍵313之轉軸部322之位置，也不限於下端部，也可為上端部或左右端部等。再者，於本實施形態3上，雖係以警報器作為火災警報器，但是也可為氣體警報器或其他種類之警報器。Although the third embodiment of the present invention has been described above, the application of the present invention is not limited to the third embodiment, and can be widely applied within the scope of the technical idea. For example, the position or size of the operation key 31 in the alarm body 301 is not limited to the third embodiment. In the third embodiment, the operation key 313 has a long shape in the vertical direction, but may have a long shape in the left-right direction, or may have a circular shape or a quadrangular shape. Further, even if the position of the rotation shaft portion 322 of the operation key 313 is not limited to the lower end portion, the upper end portion or the left and right end portions may be used. Further, in the third embodiment, the alarm device is used as the fire alarm, but it may be a gas alarm or another type of alarm.

[實施形態4] 最後，沿著圖面詳細地說明本發明之實施形態4。第25圖為表示從於本實施形態4當中之火災警報器之前面側所看到之立體圖。本實施形態4之火災警報器，係具有：可偵測發生火災且發出警報之警報器本體401；及對設置面安裝有警報器本體401之安裝板402。[Embodiment 4] Finally, Embodiment 4 of the present invention will be described in detail along the drawings. Fig. 25 is a perspective view showing the front side of the fire alarm in the fourth embodiment. The fire alarm of the fourth embodiment includes an alarm body 401 that detects a fire and emits an alarm, and a mounting plate 402 on which the alarm body 401 is attached to the installation surface.

警報器本體401，具有一框體410，該框體10係於內部具有用來偵測煙霧之感應器等。於框體410之側面部，具有煙霧流入口412，從該煙霧流入口12將煙霧導引到框體410之內部，且藉由感應器來偵測煙霧。The alarm body 401 has a frame 410 with an inductor or the like for detecting smoke inside. At the side of the frame 410, there is a smoke inflow opening 412 from which the smoke is guided into the interior of the frame 410, and the smoke is detected by the sensor.

框體410，具有一面對室內側之前面411，於前面411設置有：用來進行各種操作之操作鍵413；及用來發出來自設置於框體410內部之揚聲器之聲音的聲音孔414。The housing 410 has a front side facing surface 411, and the front surface 411 is provided with operation keys 413 for performing various operations, and sound holes 414 for emitting sound from speakers disposed inside the housing 410.

安裝板402，係設置於警報器本體401之背面側且可固定警報器本體401。固定有安裝板402之設置面，於本實施形態4上係為住宅之牆壁面。但是，住宅之天花板等，設置面其他面也可。安裝板402對著垂直面之設置面且固定後，就對著安裝板402安裝固定警報器本體401。The mounting plate 402 is disposed on the back side of the alarm body 401 and can fix the alarm body 401. The installation surface on which the mounting plate 402 is fixed is the wall surface of the house in the fourth embodiment. However, the ceiling of a house or the like may be provided on the other side of the surface. After the mounting plate 402 is opposed to the installation surface of the vertical surface and fixed, the alarm body 401 is attached and fixed to the mounting plate 402.

第26圖為表示火災警報器之縱向剖面圖。安裝板402具有螺孔部421，藉由***到該螺孔部421之螺絲22，對著設置面且加以固定。另外，安裝板402，係具有用來固定警報器本體401之背面側之警報器固定面部420。警報器本體401，係對警報器固定面部420卡合固定。Figure 26 is a longitudinal sectional view showing the fire alarm. The mounting plate 402 has a screw hole portion 421 which is fixed to the installation surface by the screw 22 inserted into the screw hole portion 421. Further, the mounting plate 402 has an alarm fixing surface 420 for fixing the back side of the alarm body 401. The alarm body 401 is engaged and fixed to the alarm fixed surface 420.

警報器本體401，於框體410上部，具有一電池收納部416，於電池收納部416內收納有電池417。另外，於框體410之內部，配置有用來偵測從煙霧流入口412流入之煙霧之煙霧偵測部430。煙霧偵測部430，係設置於被收納於框體410內之基板部432，遮掩來自外部之光線且具有用來偵測侵入之煙霧的煙霧偵測區域431，同時，具有用來覆蓋該煙霧偵測區域431之煙霧偵測部蓋體433。The alarm body 401 has a battery housing portion 416 at an upper portion of the housing 410, and a battery 417 is housed in the battery housing portion 416. Further, inside the casing 410, a smoke detecting portion 430 for detecting smoke flowing in from the smoke inflow port 412 is disposed. The smoke detecting unit 430 is disposed on the substrate portion 432 housed in the casing 410, and shields the smoke from the outside and has a smoke detecting area 431 for detecting invading smoke, and has a surface for covering the smoke. The smoke detecting portion cover 433 of the detecting area 431.

第27圖為表示具有煙霧偵測部430之基板部432之立體圖。如該圖所示，基板部432，具有部分為缺口且略為圓形，於中央部，係以覆蓋煙霧偵測部蓋體433之方式來設置。煙霧偵測部蓋體433之頂面，係圓狀之基部440。於煙霧偵測部蓋體433之外圍面部分，設置用來防止讓昆蟲等侵入到煙霧偵測區域431之網子構件434。另外，於基板部432，讓用來收納揚聲器418且固定之揚聲器收納部432a形成於周緣部。Fig. 27 is a perspective view showing the substrate portion 432 having the smoke detecting portion 430. As shown in the figure, the substrate portion 432 has a portion that is notched and has a substantially circular shape, and is provided at a central portion so as to cover the smoke detecting portion cover 433. The top surface of the smoke detecting portion cover 433 is a circular base portion 440. A mesh member 434 for preventing insects or the like from intruding into the smoke detecting region 431 is provided at a peripheral surface portion of the smoke detecting portion cover 433. Further, in the board portion 432, a speaker housing portion 432a for accommodating the speaker 418 and fixed is formed on the peripheral portion.

第28圖為表示煙霧偵測部430內部之剖面圖。於煙霧偵測部蓋體433，從基部440往基板部432直立設置有複數個之遮光璧部441。如該圖所示，煙霧偵測部蓋體433之遮光璧部441，係具有往單向而延伸之單片狀，藉由複數個之遮光璧部441而圍繞煙霧偵測區域431之整個圓周。遮光璧部441之延伸方向，也朝向煙霧偵測區域431之圓周方向與徑向之任一者。於遮光璧部441間，以可讓煙霧侵入到煙霧偵測區域431之方式，設置有間隙。另外，遮光璧部441之其中一端部411a及鄰接之遮光璧部441之另一端部441b，以於圓周方向中相互重疊之方式來配置。Fig. 28 is a cross-sectional view showing the inside of the smoke detecting unit 430. In the smoke detecting unit cover 433, a plurality of shading portions 441 are erected from the base portion 440 to the substrate portion 432. As shown in the figure, the shading portion 441 of the smoke detecting portion cover 433 has a single piece extending in a one-way direction, and surrounds the entire circumference of the smoke detecting portion 431 by a plurality of shading portions 441. . The extending direction of the shading portion 441 also faces either the circumferential direction and the radial direction of the smoke detecting region 431. A gap is provided between the shading portions 441 so that the smoke can enter the smoke detecting area 431. Further, one end portion 411a of the shading portion 441 and the other end portion 441b of the adjacent shading portion 441 are disposed to overlap each other in the circumferential direction.

於遮光璧部441之其中一端部441a之外圍面，形成有形成煙霧偵測區域431外圍面之弧狀面部441c。藉由複數個之遮光璧部441，讓弧狀面部441c，形成有斷斷續續之圓周面。沿著該弧狀面部441c，以讓網子構件434形成有煙霧偵測部蓋體433外圍面之方式，來配置固定。An arcuate surface portion 441c forming a peripheral surface of the smoke detecting region 431 is formed on a peripheral surface of one end portion 441a of the shading portion 441. The arcuate surface portion 441c is formed with a continuous circumferential surface by a plurality of shading portions 441. The arcuate surface portion 441c is disposed and fixed so that the mesh member 434 is formed with the outer surface of the smoke detecting portion cover 433.

於煙霧偵測區域431之內部，讓發光部435及感應器部436配置於設置基部437。其中，發光部435，係藉由可發光之鐳射二極體或紅外線LED等來構成，且以朝向煙霧偵測區域431之中央上方測之方式來配置。感應器部436，係配置於挾持有煙霧偵測區域431之中心之相反側且向著煙霧偵測區域431之中央上方側。感應器部436，係藉由可偵測入射到偵測位置436a之光的光二極體等來構成。Inside the smoke detecting area 431, the light emitting portion 435 and the sensor portion 436 are disposed in the installation base portion 437. The light-emitting portion 435 is configured by a light-emitting laser diode or an infrared LED or the like, and is disposed to face the center of the smoke detecting region 431. The sensor portion 436 is disposed on the opposite side of the center of the smoke detecting area 431 and facing the center of the smoke detecting area 431. The sensor portion 436 is configured by a photodiode or the like that can detect light incident on the detection position 436a.

來自發光部435之光，由於係往感應器部436之斜上方來射出，所以通常係不會到於感應器部436中的光。另外，若煙霧侵入到煙霧偵測區域431的話，會藉由煙霧來散射來自發光部435之光而讓部分之光線入射到感應器部436之偵測位置436a。藉此，感應器部436即可偵測到光線且可偵測出煙霧之存在。The light from the light-emitting portion 435 is emitted obliquely upward from the inductor portion 436, so that the light in the sensor portion 436 is not normally obtained. In addition, if the smoke invades the smoke detecting area 431, the light from the light emitting portion 435 is scattered by the smoke to allow a part of the light to enter the detecting position 436a of the sensor portion 436. Thereby, the sensor portion 436 can detect light and detect the presence of smoke.

煙霧偵測區域431，係藉由以遮光璧部441圍繞整個圓周，不讓來自外部之光線入射，另外，遮光璧部441，係藉由幾乎不反射光之素材來形成。但是，於與發光部435對向之遮光璧部441之中，由於可直接接收來自發光部435之強烈光線，所以可反射部分之光線。藉由讓該反射光入射到感應器部436，儘管煙霧不存在，也有可能利用感應器部436來偵測出光線。為了防止此現象發生，於接收來自發光部435之光線的遮光璧部441之內圍面，形成有凹凸面部441d。若以凹凸面部441d來反射光線時，由於係藉由該凹凸來散射光線，所以對感應器部436之偵測位置436a來說會減少入射之反射光的光量且以可防止誤動作之發生。The smoke detecting area 431 is formed by the light-shielding dam portion 441 surrounding the entire circumference so as not to allow light from the outside to be incident, and the light-shielding dam portion 441 is formed by a material that hardly reflects light. However, in the light-shielding dam portion 441 opposed to the light-emitting portion 435, since a strong light from the light-emitting portion 435 can be directly received, part of the light can be reflected. By allowing the reflected light to be incident on the sensor portion 436, it is possible to detect the light using the sensor portion 436 despite the absence of smoke. In order to prevent this from occurring, an uneven surface portion 441d is formed on the inner peripheral surface of the light-shielding dam portion 441 that receives the light from the light-emitting portion 435. When the light is reflected by the uneven surface portion 441d, since the light is scattered by the unevenness, the amount of reflected light incident on the sensor portion 436 is reduced to prevent the occurrence of malfunction.

第29圖為表示第28圖中之煙霧偵測區域431附近之放大圖。於從感應器部436之偵測位置436a往放射線狀延伸之線當中，通過遮光璧部441之另一端部441b之線，係從遮光璧部441之另一端部441b且於外圍側之中，與鄰接之遮光璧部441之其中一端部441a相交。譬如，虛線R1之線，通過遮光璧部441之另一端部441b而位於鄰接之遮光璧部441之其中一端部441a。即使於虛線R2及虛線R3中也同樣。再者，即使於以虛線R1~R3所示之以外之遮光璧部441也同樣。換言之，於以感應器部436之偵測位置436a為中心之放射線上，務必能夠讓遮光璧部411之任一者被定位。如此一來，遮光璧部411，能讓從外部入射到煙霧偵測區域431之光線，以不會直接到達感應器部436之偵測位置436a之方式來配置。Fig. 29 is an enlarged view showing the vicinity of the smoke detecting area 431 in Fig. 28. Among the lines extending radially from the detection position 436a of the sensor portion 436, the line passing through the other end portion 441b of the light-shielding portion 441 is from the other end portion 441b of the light-shielding portion 441 and on the peripheral side. One end portion 441a of the adjacent shading portion 441 is intersected. For example, the line of the broken line R1 is located at one end portion 441a of the adjacent shading portion 441 through the other end portion 441b of the shading portion 441. The same is true even in the broken line R2 and the broken line R3. The same applies to the light-shielding dam portion 441 other than the one shown by the broken lines R1 to R3. In other words, it is essential that any of the light-shielding jaws 411 can be positioned on the radiation line centering on the detection position 436a of the sensor portion 436. In this way, the light-shielding portion 411 allows the light incident from the outside to the smoke detecting region 431 to be disposed so as not to directly reach the detecting position 436a of the sensor portion 436.

如此一來，於以感應器部436之偵測位置436a為中心之放射線上，以定位遮光璧部441之任一者之方式，讓遮光璧部441彼此間於徑向中相互重疊之方式來配置，所以來自通過遮光璧部441之間的間隙之外部光線，不會直接到達感應器部436之偵測位置436a，且於感應器部436上，能夠偵測出僅來自發光部435之散射光，且可確實地防止因為外部光線所導致之感應器部436之誤動作。另外，遮光璧部411，並非僅感應器部436之偵測位置436a，且可阻止讓外部光線入射到煙霧偵測區域431之中央區域。於煙霧偵測區域431中，若讓外部光陷入射到發光部435及感應器部436之間的區域的話，則會藉由低濃度之煙霧等來散射，即使光線無直接入射到感應器部436之偵測位置436a，也可間接地入射到此而可能導致誤動作，但是由於可利用遮光璧部411來阻止對煙霧偵測區域431之中央區域的外部光入射，所以可防止誤動作。In this way, the light-shielding dam portions 441 are overlapped with each other in the radial direction so as to locate the light-shielding dam portion 441 on the radiation line centering on the detection position 436a of the sensor portion 436. Therefore, the external light from the gap between the light-shielding portions 441 does not directly reach the detection position 436a of the sensor portion 436, and on the sensor portion 436, the scattering from only the light-emitting portion 435 can be detected. Light, and can reliably prevent malfunction of the sensor portion 436 due to external light. In addition, the shading portion 411 is not only the detection position 436a of the sensor portion 436, but also prevents external light from entering the central portion of the smoke detecting region 431. In the smoke detecting area 431, if external light is trapped in the area between the light emitting portion 435 and the sensor portion 436, it is scattered by a low concentration of smoke or the like, even if the light is not directly incident on the sensor portion. The detection position 436a of the 436 may be indirectly incident thereon, which may cause malfunction. However, since the shading portion 411 can be used to prevent external light from entering the central portion of the smoke detecting region 431, malfunction can be prevented.

遮光璧部441，具有往單向延伸之單片形狀，且利用於遮光璧部441彼此間之徑向中之相互重疊也為所需之最低限，所以可縮小煙霧偵測部蓋體433之直徑。於第28圖中，雖以虛線表示收納於揚聲器收納部432a之揚聲器418，但是揚聲器418與遮光璧部441，於框體410之厚度中係以相互不重疊之方式來配置。因此，不會因為遮光璧部441而遮掩來自揚聲器418之聲音，且可充分確保警報時之音壓。另外，由於可縮小煙霧偵測部蓋體433之直徑，所以可達到警報器本體401之小型化。The light-shielding dam portion 441 has a single-piece shape extending in one direction, and the overlap between the light-shielding dam portions 441 in the radial direction is also a minimum required, so that the smoke detecting portion cover 433 can be reduced. diameter. In the figure 28, the speaker 418 housed in the speaker housing portion 432a is indicated by a broken line. However, the speaker 418 and the light-shielding portion 441 are disposed so as not to overlap each other in the thickness of the housing 410. Therefore, the sound from the speaker 418 is not blocked by the shading portion 441, and the sound pressure at the time of the alarm can be sufficiently ensured. Further, since the diameter of the smoke detecting portion cover 433 can be reduced, the size of the alarm body 401 can be reduced.

Cut in the down direction (-Z direction). Further, the component case notch 5617 is not provided by the height direction (Z direction), and is formed as a notch of a half height of the component case 5616. Further, the upper (+Z direction) portion is referred to as a "stop portion" 5618 as compared with the component case notch 5617 in the component case 5616.

且，若組裝底殼521及偵測部本體504時，上述電池固定彈簧548係插通於零件盒缺口5617，且於電池固定彈簧548之施力空間549內部，介入有檔止部5618。如此一來，於施力空間549內部藉由介入有檔止部5618，讓往電池固定彈簧548之內側方向（＋X方向）之捲繞可藉由該檔止部5618來限制，所以可以防止於收納電池時讓電池固定彈簧548因為過度捲繞而塑料變形。如此一來，於本實施形態5上，電池固定彈簧548係不與檔止部5618一體性設置於底殼521而係設置於與底殼521為分離構造之偵測部本體504。因此，相較於將電池固定彈簧548設置於底殼521之零件盒5616之情況，可將電池固定彈簧548之前端位置（－X方向端部之位置）抑制於內側（＋X方向且可讓零件盒5616為小型化。如此一來，藉由讓妨礙往偵測空間534之氣流之零件的零件盒5616為小型化，可增加往偵測空間534之氣體流入且可改善偵測精密度。另外，如同電池固定彈簧548般，於收納電池時，讓經常從電池產生應力之零件，藉由形成於從外部無法辨識之偵測部本體504，相較於在殼體502形成電池固定彈簧548來說，可防止伴隨著基於上述應力之變形而產生外觀不良。When the bottom case 521 and the detecting unit body 504 are assembled, the battery fixing spring 548 is inserted into the component case notch 5617, and the stopper portion 5618 is interposed in the biasing space 549 of the battery fixing spring 548. In this way, by inserting the stopper portion 5618 into the urging space 549, the winding toward the inner side (+X direction) of the battery fixing spring 548 can be restricted by the stopper portion 5618, so that it can be prevented. When the battery is housed, the battery fixing spring 548 is deformed due to excessive winding. As described above, in the fifth embodiment, the battery fixing spring 548 is not integrally provided with the stopper portion 5618 in the bottom case 521, and is provided on the detecting portion main body 504 which is separated from the bottom case 521. Therefore, compared with the case where the battery fixing spring 548 is disposed in the component case 5616 of the bottom case 521, the position of the front end of the battery fixing spring 548 (the position of the end portion in the -X direction) can be suppressed to the inner side (+X direction and the parts can be made The cartridge 5616 is miniaturized. As a result, by minimizing the component case 5616 that blocks the airflow to the detection space 534, the gas flow into the detection space 534 can be increased and the detection precision can be improved. As with the battery fixing spring 548, when the battery is housed, the component that constantly generates stress from the battery is formed by the detecting portion body 504 that is not recognized from the outside, and the battery fixing spring 548 is formed in the housing 502. It is said that appearance defects accompanying deformation based on the above stress can be prevented.

（構造－詳細－偵測部本體－揚聲器收納部） 揚聲器收納部545，係用來收納進行警報輸出之揚聲器的收納手段，且與偵測部本體504為一體成形之收納手段。該揚聲器收納部545，係板狀構件，該板狀構件係往形成於與於偵測部本體504當中之揚聲器對應的位置之下方向（－Z方向）而突出，具有比起揚聲器外形稍微較大內徑的圓環狀之構件。於此，所謂「稍微較大」，係至少可收納揚聲器之大小的任意範圍，譬如於揚聲器外圍與揚聲器收納部545內圍之間，形成有數毫米間隙之大小也不拘。於此，於形成有於偵測部本體504當中之揚聲器收納部545之位置，形成有如第50圖之複數個揚聲器孔，也可讓從揚聲器發出之警報聲，透過該揚聲器孔往上方（＋Z方向）流動。(Structure-Detail-Detection Unit Main Body-Speaker Storage Unit) The speaker storage unit 545 is a storage means for accommodating a storage means for receiving an alarm output, and is integrally formed with the detection unit main body 504. The speaker housing portion 545 is a plate-like member that protrudes in a direction (-Z direction) formed below a position corresponding to a speaker in the detecting portion body 504, and has a slightly larger shape than a speaker. A large inner diameter annular member. Here, the term "slightly larger" is at least an arbitrary range in which the size of the speaker can be accommodated, for example, a gap of several millimeters is formed between the periphery of the speaker and the inner circumference of the speaker housing portion 545. Here, a plurality of speaker holes as shown in FIG. 50 are formed at a position of the speaker housing portion 545 formed in the detecting unit body 504, and an alarm sound emitted from the speaker can be transmitted upward through the speaker hole (+Z Direction) flow.

（構造－詳細－配置凹部） 其次，說明有關於偵測部本體504當中之配置凹部5431之周邊。第52圖為表示第32圖之B-B箭頭所示之剖面圖，第53圖為表示第52圖之C-C箭頭所示之剖面圖。如此等第52圖及第53圖或者上述第45圖至第47圖所示，於偵測部本體504當中之上面（＋Z側面），概要地設置有發光凹陷部5432，感光凹陷部5433，凹槽部5434及外緣璧5435，另外，如上述之第51圖所示，於偵測部本體504當中下側的面（與電路基板551為對向之側的面。－Z側的面），設置有 遮光框體部5438。又，於第53圖中，一點虛線為表示發光部552之光軸，二點虛線為表示感光部553之光軸。(Structure - Detail - Arrangement of Concave Portion) Next, the periphery of the disposition recessed portion 5431 in the detecting portion main body 504 will be described. Fig. 52 is a cross-sectional view showing the arrow B-B in Fig. 32, and Fig. 53 is a cross-sectional view showing the arrow C-C in Fig. 52. Thus, as shown in FIG. 52 and FIG. 53 or the above-mentioned 45th to 47th, the upper surface (+Z side) of the detecting portion body 504 is provided with a light-emitting recess portion 5432, a photosensitive recess portion 5433, and a concave portion. The groove portion 5434 and the outer edge 璧 5435 are also the lower surface of the detecting portion main body 504 (the surface facing the circuit board 551 on the side opposite to the -Z side) as shown in Fig. 51 described above. A light shielding frame body 5438 is provided. Further, in Fig. 53, a one-dotted line indicates the optical axis of the light-emitting portion 552, and a two-dotted line indicates the optical axis of the light-receiving portion 553.

（構造－詳細－配置凹部－發光凹陷部） 發光凹陷部5432，係抑制偵測精密度降低手段，該抑制偵測精密度降低手段係可抑制伴隨讓塵埃位於發光部522之光軸上之偵測精密度降低。具體而言，該發光凹陷部5432，係相較於配置凹部5431之中央，於發光部552側之位置上係與配置凹部5431為一體成形之凹部，且具體形狀為任意，但是於本實施形態5中，如第53圖所示，最外側之面呈現為斜面之剖面視之為梯形的凹部。(Structure-detail-arrangement recess-light-emitting recessed portion) The illuminating recessed portion 5432 is a means for suppressing the detection precision reduction means for suppressing the accompanying dust on the optical axis of the light-emitting portion 522 The precision of measurement is reduced. Specifically, the light-emitting recessed portion 5432 is a concave portion integrally formed with the arrangement concave portion 5431 at a position on the light-emitting portion 552 side with respect to the center of the arrangement concave portion 5431, and has a specific shape. However, this embodiment is arbitrary. In Fig. 53, as shown in Fig. 53, the outermost surface is a concave portion having a trapezoidal cross section as a trapezoidal shape.

於此，於該斜面之部分，形成有貫通偵測部本體504之發光孔5436。該發光孔5436，係用來從發光部552通過偵測部本體504且將光線導入到偵測空間534之孔。具體而言，為設置於發光凹陷部5432當中之發光部552之光軸上的孔，且以貫通發光凹陷部5432之斜面之方式而形成。該發光孔5436之直徑大小或形狀，係可將發光部552之光線導入到偵測空間534之任意範圍，譬如，基於發光部552之光線的投射角度或光量等且藉由實驗或分析等即可決定適當之大小或形狀。Here, a light-emitting hole 5436 penetrating the detecting portion body 504 is formed in a portion of the inclined surface. The light-emitting hole 5436 is configured to pass the light-emitting portion 552 through the detecting portion body 504 and introduce light into the hole of the detecting space 534. Specifically, it is a hole provided in the optical axis of the light-emitting portion 552 among the light-emitting recess portions 5432, and is formed to penetrate the slope of the light-emitting recess portion 5432. The diameter or shape of the light-emitting hole 5436 can introduce the light of the light-emitting portion 552 into any range of the detection space 534, for example, based on the projection angle or amount of light of the light-emitting portion 552, and the like by experiment or analysis. The appropriate size or shape can be determined.

返回到發光凹陷部5432之說明，如此地，設置發光凹陷部5432，相較於發光孔5436且藉由讓內側位置（於第53圖當中之右方）下凹，即使塵埃多少塵積於發光凹陷部5432之底面且塵埃已塵積到發光孔5436之高度，也不會讓塵埃位於光軸上。因此，可抑制伴隨讓塵埃位於發光部552之光軸上而降低偵測精密度之情況發生。於此，該發光凹陷部5432之深度，較佳係可用來防止因為塵埃之塵積而降低偵測精密度之大概深度。也就是說，若發光凹陷部5432深度太淺的話，雖僅隱約地讓塵埃塵積於發光凹陷部5432之底面，而讓該塵埃位於發光部552之光軸上，且可能會發生讓光線反射到塵埃而導致誤偵測煙霧之情況，但藉由加深發光凹陷部5432且可塵積多些塵埃，即可防止如此情況發生。惟，若深度過深的話，偵測部本體504整體厚度會變厚，進而讓整體之警報裝置100大型化，此並非最佳者。又，於本實施形態5之中，呈現深度為略3mm之凹部。Returning to the description of the light-emitting recessed portion 5432, in this manner, the light-emitting recessed portion 5432 is provided, and the inner side position (the right side in FIG. 53) is recessed compared to the light-emitting hole 5436, even if dust is scattered on the light The bottom surface of the depressed portion 5432 and dust has been dusted to the height of the light-emitting hole 5436, and the dust is not allowed to be positioned on the optical axis. Therefore, it is possible to suppress the occurrence of a situation in which the dust is placed on the optical axis of the light-emitting portion 552 to reduce the detection precision. Herein, the depth of the light-emitting recessed portion 5432 is preferably used to prevent the depth of the detection precision from being lowered due to dust accumulation. That is, if the depth of the light-emitting recessed portion 5432 is too shallow, dust is only faintly allowed to accumulate on the bottom surface of the light-emitting recessed portion 5432, and the dust is placed on the optical axis of the light-emitting portion 552, and light reflection may occur. In the case of dust, the smoke is detected by mistake, but this can be prevented by deepening the light-emitting recess 5432 and dusting a lot of dust. However, if the depth is too deep, the overall thickness of the detecting unit body 504 is increased, and the overall alarm device 100 is increased in size, which is not preferable. Further, in the fifth embodiment, a concave portion having a depth of 3 mm is formed.

（構造－詳細－配置凹部－感光凹陷部） 感光凹陷部5433，係抑制偵測精密度降低手段，該抑制偵測精密度降低手段係可抑制伴隨讓塵埃位於感光部553之光軸上之偵測精密度降低。具體而言，該感光凹陷部5433，係相較於配置凹部5431之中央，於感光部553側之位置上係與配置凹部5431為一體成形之凹陷且具體之形狀為任意，但是於本實施形態5中，如第50圖所示，最外側之面呈現為斜面之剖面視之為梯形的凹部。(Structure-Detail-Configuration Concave-Photosensitive Depression) The photosensitive recessed portion 5433 is a means for suppressing the detection precision reduction, and the suppression detection precision reduction means suppresses the detection of the dust on the optical axis of the photosensitive portion 553. The precision of measurement is reduced. Specifically, the photosensitive recessed portion 5433 is recessed integrally with the disposition recessed portion 5431 at a position on the side of the photoreceptor portion 553 at a position closer to the center of the recessed portion 5431, and the specific shape is arbitrary. In Fig. 50, as shown in Fig. 50, the outermost surface is a concave portion having a trapezoidal cross section as a trapezoidal shape.

於此，於該斜面之部分，形成有感光孔5437。該感光孔5437，係用來從偵測空間534通過偵測部本體504且將光線導入到感光部553之孔。具體而言，為設置於感光凹陷部5433當中之感光部553之光軸上的孔，且以貫通感光凹陷部5433之斜面之方式而形成。該感光孔5437之直徑大小或形狀，係可將光線導入到感光部553之任意範圍，譬如，設置於感光部553之偵測空間534側的面且以具有聚光功能之透鏡部（省略符號）相同大小或形狀而形成即可。Here, a photosensitive hole 5437 is formed in a portion of the slope. The photosensitive aperture 5437 is used to pass the detection portion 504 from the detection space 534 and introduce light into the aperture of the photosensitive portion 553. Specifically, it is a hole provided in the optical axis of the photosensitive portion 553 among the photosensitive recess portions 5433, and is formed to penetrate the slope of the photosensitive recess portion 5433. The diameter or shape of the photosensitive hole 5437 is such that light can be introduced into any range of the photosensitive portion 553, for example, a surface disposed on the side of the detection space 534 of the photosensitive portion 553 and having a lens portion having a collecting function (omitted symbol) The same size or shape can be formed.

返回到感光凹陷部5433之說明，如此地，設置感光凹陷部5433，相較於感光孔5437且藉由讓內側位置（於第53圖當中之右方）下凹，即使塵埃多少塵積於感光凹陷部5433之底面，且塵埃已塵積到發光孔5436之高度，也不會讓塵埃位於光軸上。因此，可抑制伴隨讓塵埃位於感光部553之光軸上而降低偵測精密度之情況發生。於此，該感光凹陷部5433之深度，係與上述發光凹陷部5432相同，較佳係可用來防止因為塵埃之塵積而降低偵測精密度之大概深度。又，於本實施形態5之中，呈現深度為略3mm之凹部。Returning to the description of the photosensitive recessed portion 5433, in this manner, the photosensitive recessed portion 5433 is provided, compared to the photosensitive via 5437 and by recessing the inner position (to the right in FIG. 53), even if dust is accumulated in the photosensitive The bottom surface of the recessed portion 5433, and the dust has been dusted to the height of the light-emitting hole 5436, and the dust is not allowed to be located on the optical axis. Therefore, it is possible to suppress the occurrence of a situation in which the dust is placed on the optical axis of the photosensitive portion 553 to reduce the detection precision. Herein, the depth of the photosensitive recessed portion 5433 is the same as that of the above-mentioned light-emitting recessed portion 5432, and is preferably used to prevent the depth of detection precision from being lowered due to dust accumulation. Further, in the fifth embodiment, a concave portion having a depth of 3 mm is formed.

（構造－詳細－配置凹部－凹部） 凹槽部5434，係形成於發光孔5436及感光孔5437之周圍，該發光孔5436及感光孔5437之周圍係於偵測部本體504當中且於與偵測空間534為對向之面之中，且朝向與偵測空間534為反側而下凹之凹槽。具體而言，凹槽部5434，係以覆蓋發光凹陷部5432及感光凹陷部5433周圍之方式，與配置凹部5431為一體成形之凹槽，相較於配置凹部5431而言，係進一步朝向與偵測空間534為相反側（也就是說為下側）且較低之台階部分。如此地，於配置凹部5431中，藉由設置有較低之台階的凹槽部5434，可讓浸滲到偵測空間534之塵埃塵積於該凹槽部5434，所以可防止讓塵埃堆高於元件蓋子546之表面上。因此，可防止藉由讓塵積之塵埃位於發光部552或感光部553之光軸上，而導致降低偵測精密度之情況發生。又，雖凹槽部5434之深度可為任意，但是譬如也可為從略1mm至2mm之深度。(Structure-detail-arrangement recess-recess) The groove portion 5434 is formed around the light-emitting hole 5436 and the light-receiving hole 5437, and the periphery of the light-emitting hole 5436 and the light-receiving hole 5437 is in the detecting portion body 504 and is detected The measurement space 534 is a recess that is recessed toward the opposite side of the detection space 534. Specifically, the recessed portion 5434 is formed integrally with the recessed portion 5431 so as to cover the periphery of the light-emitting recessed portion 5432 and the photosensitive recessed portion 5433. Compared with the recessed portion 5431, the recessed portion 5434 is further oriented toward the detector. The measurement space 534 is the opposite side (that is, the lower side) and the lower step portion. In this way, in the arrangement concave portion 5431, the dust portion impregnated into the detection space 534 can be accumulated in the groove portion 5434 by the groove portion 5434 provided with the lower step, so that the dust can be prevented from being piled up. On the surface of the component cover 546. Therefore, it is possible to prevent the dust from being dusted on the optical axis of the light-emitting portion 552 or the light-receiving portion 553, resulting in a decrease in the detection precision. Further, although the depth of the groove portion 5434 may be arbitrary, it may be, for example, a depth of slightly 1 mm to 2 mm.

（構造－詳細－配置凹部－外緣璧） 外緣璧5435，係於偵測部本體504之偵測空間534側之面當中之發光凹陷部5432及感光凹陷部5433周圍，從偵測部本體504往偵測空間534側為豎立之強璧部。具體而言，外緣璧5435，係設置於凹槽部5434表面且為樹脂製之牆壁，沿著發光凹陷部5432及感光凹陷部5433之裝配面側（也就是說為上面側）之外緣所形成之牆壁。該外緣璧5435之厚度，雖為任意可維持充分強度範圍即可，但是於本實施形態5上，係呈現約1mm之厚度之板狀體。另外，外緣璧5435之高度為不干擾到光軸之範圍即可，譬如，於本實施形態5上，雖可形成為約1.5mm之均勻高度，但並非限定於此也可形成為不均勻之高度。(Structure-detail-arrangement recess-outer edge 璧) The outer edge 璧 5435 is disposed around the light-emitting recessed portion 5432 and the photosensitive recessed portion 5433 in the surface of the detecting portion 504 on the detecting space 534 side, from the detecting portion body The 504 is a strong armpit that is erected toward the detection space 534 side. Specifically, the outer edge 璧 5435 is provided on the surface of the groove portion 5434 and is a resin-made wall, along the outer side of the mounting surface side (that is, the upper side) of the light-emitting recess portion 5432 and the photosensitive recess portion 5433 The walls formed. Although the thickness of the outer edge 璧 5435 is sufficient to maintain a sufficient strength range, in the fifth embodiment, a plate-like body having a thickness of about 1 mm is used. Further, the height of the outer edge 璧 5435 may be a range that does not interfere with the optical axis. For example, in the fifth embodiment, the height can be formed to a uniform height of about 1.5 mm, but the shape is not limited thereto. The height.

如此地，藉由設置外緣璧5435，如第53圖所示，讓外緣璧5435位於發光部552及感光部553之相互間，所以可防止不透過偵測空間534而直接讓感光部553感光，且可防止誤偵測之情況發生。另外，藉由該外緣璧5435，可防止讓塵積於凹槽部5434之塵埃透過發光孔5436或感光孔5437而往發光部552或感光部553掉落之情況發生，且也可防止伴隨塵埃塵積於發光部552或感光部553表面而降低偵測精密度之情況發生。再者，可防止讓塵積於凹槽部5434之塵埃，從凹槽部5434掉落且塵積到發光凹陷部5432之底面或感光凹陷部5433之底面之情況發生，且也可防止伴隨讓塵積於發光凹陷部5432之底面或感光凹陷部5433之底面的塵埃，位於發光部552或感光部553之光軸上而導致降低偵測精密度之情況發生。In this manner, by providing the outer edge 璧 5435, as shown in FIG. 53, the outer edge 璧 5435 is positioned between the light-emitting portion 552 and the light-receiving portion 553, so that the photosensitive portion 553 can be prevented from directly passing through the detection space 534. Sensitive and prevents false detections from occurring. Further, by the outer edge 璧 5435, it is possible to prevent the dust accumulated in the groove portion 5434 from passing through the light-emitting hole 5436 or the light-receiving hole 5437 and falling toward the light-emitting portion 552 or the light-receiving portion 553, and it is also possible to prevent the accompanying Dust is deposited on the surface of the light-emitting portion 552 or the light-receiving portion 553 to reduce the detection precision. Further, it is possible to prevent dust accumulated in the groove portion 5434 from falling from the groove portion 5434 and dusting to the bottom surface of the light-emitting recess portion 5432 or the bottom surface of the photosensitive recess portion 5433, and it is also possible to prevent accompanying Dust accumulated on the bottom surface of the light-emitting recessed portion 5432 or the bottom surface of the light-receiving recessed portion 5433 is located on the optical axis of the light-emitting portion 552 or the light-receiving portion 553, resulting in a decrease in detection precision.

（構造－詳細－配置凹部－遮光框體部） 遮光框體部5438，係遮光手段，該遮光手段係形成於發光孔5436或感光孔5437之周圍，該發光孔5436或感光孔5437係位於偵測部本體504當中且與電路基板551為對向面之中，朝向基板且以豎立之方式配置，為覆蓋發光部552及感光部553之周圍的遮光手段。該遮光框體部5438，具體而言，係下面為開口面之框體狀，且從偵測部本體504下面（－Z方向面）往下方以突出之方式來形成。且，當組裝偵測部本體504及電路基板551之際，係讓安裝於電路基板551之發光部552及感光部553收容於遮光框體部5438內部，且以覆蓋發光部552及感光部553前後左右之方式來配置。(structure-detail-arrangement recessed portion-light-shielding frame portion) The light-shielding frame portion 5438 is a light-shielding means formed around the light-emitting hole 5436 or the photosensitive hole 5437, and the light-emitting hole 5436 or the photosensitive hole 5437 is located Among the measurement unit main body 504 and the circuit board 551 as a counter surface, the substrate is disposed so as to be erected toward the substrate, and is a light shielding means for covering the periphery of the light-emitting portion 552 and the light-receiving portion 553. Specifically, the light-shielding frame portion 5438 is formed in a frame shape having an open surface on the lower surface, and is formed to protrude downward from the lower surface (the -Z direction surface) of the detecting portion main body 504. When the detection unit body 504 and the circuit board 551 are assembled, the light-emitting portion 552 and the light-receiving portion 553 attached to the circuit board 551 are housed inside the light-shielding frame portion 5438, and cover the light-emitting portion 552 and the light-receiving portion 553. Configure before and after.

如此地，於遮光框體部5438藉由覆蓋發光部552及感光部553，即可防止讓偵測光不透過偵測空間534（也就是說，圍繞偵測部本體504下方）而從發光部552到達感光部553之情況發生，且也可讓光線往正確路徑（從發光部552來的光線依序透過發光孔5436，偵測空間534，感光孔5437而到達感光部553之路徑）通過，且可防止誤偵測。又，於本實施形態5上，遮光框體部5438，雖係類似覆蓋發光部552及感光部553兩者之形狀，但是並非限定於此，也可為僅覆蓋任一者之形狀。In this manner, the light-shielding frame portion 5438 can prevent the detection light from passing through the detection space 534 (that is, surrounding the detection portion body 504) from the light-emitting portion by covering the light-emitting portion 552 and the light-receiving portion 553. The 552 reaches the photosensitive portion 553, and the light can be passed to the correct path (the light from the light-emitting portion 552 sequentially passes through the light-emitting hole 5436, the detection space 534, and the photosensitive hole 5437 reaches the photosensitive portion 553). And can prevent false detection. Further, in the fifth embodiment, the light-shielding frame portion 5438 is similarly shaped to cover both the light-emitting portion 552 and the light-receiving portion 553. However, the present invention is not limited thereto, and may be formed to cover only one of the shapes.

Fig. 54 is a perspective view showing the circuit board 551. As shown in FIG. 54, the circuit board 551 is substantially provided with a light-emitting portion 552, a light-receiving portion 553, a shield 554, and a substrate hole 556.

首先，發光部552，係對偵測空間534發光之發光手段（發光側偵測手段），且朝向警報裝置5100之裝配面來投射光線之投射光線手段，作為習知之發光二極體而形成，以既定角度且於彎折狀態下，藉由將2條連接線（接腳）裝配於電路基板551，確定既定角度之光軸。First, the light-emitting portion 552 is a light-emitting means (light-emitting side detecting means) for detecting the light emitted by the detecting space 534, and a light-emitting means for projecting light toward the mounting surface of the alarm device 5100 is formed as a conventional light-emitting diode. The optical axis of a predetermined angle is determined by mounting two connecting wires (pins) on the circuit board 551 at a predetermined angle and in a bent state.

另外，感光部553，係感光手段，該感光手段係用來感光從發光部552往偵測空間534投射光線之光線之反射光，另外，基於感光之光線的光量偵測出是否含有被偵測物質（感光側偵測手段），作為習知之光二極體而形成，且與屏蔽554一體成形。In addition, the light-receiving portion 553 is a light-sensing means for detecting light reflected from the light-emitting portion 552 to the detection space 534, and detecting whether the light is detected based on the light amount of the light. The substance (photosensitive side detecting means) is formed as a conventional photodiode and integrally formed with the shield 554.

另外，屏蔽554，係用來防止干擾到感光部553之防干擾手段，且藉由讓感光部553以朝向既定方向之方式且與感光部553一體成形，確定感光部553之光軸的防干擾手段，具體而言，該屏蔽554，於電路基板551之上側（＋Z方向）之面，以與發光部552為對向之方式配置，於屏蔽554當中之底面，係與電路基板551成平行，與於屏蔽554當中之發光部552為對向側的面，相較於垂直來說係僅以既定角度而傾斜之傾斜面（裝配有感光部553之面），讓此等之底面及傾斜面形成為銳角。也就是說，將屏蔽554裝配於電路基板551之時間點上，係藉由屏蔽554之形狀來確定感光部553之光軸。In addition, the shield 554 is used to prevent interference with the anti-interference means of the photosensitive portion 553, and the anti-interference of the optical axis of the photosensitive portion 553 is determined by allowing the photosensitive portion 553 to be integrally formed with the photosensitive portion 553 in a predetermined direction. Specifically, the shield 554 is disposed on the upper surface (+Z direction) of the circuit board 551 so as to face the light-emitting portion 552, and the bottom surface of the shield 554 is parallel to the circuit board 551. The light-emitting portion 552 of the shield 554 is a surface on the opposite side, and the inclined surface (the surface on which the photosensitive portion 553 is mounted) which is inclined only at a predetermined angle as compared with the vertical direction, allows the bottom surface and the inclined surface Formed as an acute angle. That is, when the shield 554 is mounted on the circuit substrate 551, the optical axis of the photosensitive portion 553 is determined by the shape of the shield 554.

另外，基板孔556，係設置於與於發光部552當中之彎折部分為對應之位置的孔，且係可插通用來確定對發光部552之電路基板551的安裝角度之光軸調整銷5701的孔。具體而言，基板孔556，係藉由發光部552之連接線之安裝位置而形成於感光部553側的孔，該孔之形狀或直徑，雖為可插通光軸調整銷5701之任意範圍即可，但是於本實施形態上係直徑約為5mm的圓孔。於此，所謂「光軸調整銷」5701，係用於確定對發光部552之電路基板551的安裝角度時之角度確定器具，譬如含有任意棒狀之夾具（jig）的概念。又，與於發光部552當中之基板孔556為對向側之面為曲面。光軸調整銷5701之前端，較佳係以易於固定發光部552之方式且對應於該曲面之行狀的凹面。Further, the substrate hole 556 is provided in a hole corresponding to the bent portion of the light-emitting portion 552, and is an optical axis adjustment pin 5701 that can be inserted and used to determine the mounting angle of the circuit board 551 of the light-emitting portion 552. Hole. Specifically, the substrate hole 556 is a hole formed on the side of the photosensitive portion 553 by the attachment position of the connection line of the light-emitting portion 552, and the shape or diameter of the hole is an arbitrary range in which the optical axis adjustment pin 5701 can be inserted. However, in the present embodiment, it is a circular hole having a diameter of about 5 mm. Here, the "optical axis adjustment pin" 5701 is an angle determining device for determining the attachment angle of the circuit board 551 of the light-emitting portion 552, for example, a jig having an arbitrary rod shape. Further, the surface of the substrate hole 556 in the light-emitting portion 552 is a curved surface on the opposite side. The front end of the optical axis adjustment pin 5701 is preferably a concave surface that is easy to fix the light-emitting portion 552 and corresponds to the line shape of the curved surface.

（構造－詳細－上蓋） 接著，詳細說明上蓋522。於此，於上蓋522之上面（＋Z方向側之面），往上方向（＋Z方向）形成突起之堵塞突起5226（茲參考第35圖或第41圖）。該堵塞突起5226，於收容有發光部552，感光部553及偵測部本體504之狀態下，為堵住基板孔556之堵塞手段，同時，為可支撐發光部552之支撐手段。具體而言，該堵塞突起5226，係設置於對應到於上蓋522當中之電路基板551的基板孔556位置（基板孔556正下方（－Z方向）之位置），對基板孔556具有可插通之直徑的突起。於此，所謂「可插通」，係具有小於基板孔556內徑之外徑。較佳者為接近於基板孔556之內徑且較大之外徑。如此一來，藉由堵塞突起5226來堵塞基板孔556，可防止讓發光部552之光線通過基板孔556而回繞到電路基板551之下方（－Z方向），且可降低讓感光部553接受該回繞之光線而誤偵測到煙霧之可能性。再者，當使用可見光作為發光部552之光線情況下，也可防止讓該可見光透過基板孔556而伴隨反射到上蓋522而導致外觀不良情況發生。(Structure - Detail - Top Cover) Next, the upper cover 522 will be described in detail. Here, on the upper surface of the upper cover 522 (the surface on the +Z direction side), a protruding blocking protrusion 5226 is formed in the upward direction (+Z direction) (refer to Fig. 35 or Fig. 41). The clogging protrusion 5226 is a clogging means for blocking the substrate hole 556 in a state in which the light-emitting portion 552, the light-receiving portion 553, and the detecting portion main body 504 are housed, and is a supporting means for supporting the light-emitting portion 552. Specifically, the clogging protrusion 5226 is disposed at a position corresponding to the substrate hole 556 of the circuit substrate 551 in the upper cover 522 (a position directly below the substrate hole 556 (-Z direction)), and is detachable to the substrate hole 556. The protrusion of the diameter. Here, the "pluggable" has an outer diameter smaller than the inner diameter of the substrate hole 556. Preferably, it is close to the inner diameter of the substrate hole 556 and has a large outer diameter. In this way, by blocking the protrusions 5226 to block the substrate holes 556, the light of the light-emitting portion 552 can be prevented from being rewound under the circuit substrate 551 (-Z direction) through the substrate holes 556, and the light-receiving portion 553 can be reduced. The possibility of false detection of smoke by the light that is circumvented. Further, when visible light is used as the light of the light-emitting portion 552, it is possible to prevent the visible light from being transmitted through the substrate hole 556 and being reflected to the upper cover 522, resulting in appearance failure.

於此，堵塞突起5226之高度（Z方向之長度），至少於上蓋522設置電路基板551之際，具有可讓堵塞突起5226之前端插通於基板孔556的大約長度範圍即可，但是為可支撐發光部552之長度為更佳。所謂「可支撐發光部552」，係表示藉由支撐發光部552可防止於發光部552施加撞擊等時，讓發光部552之連接線產生彎曲之情況，譬如，包含有：藉由讓堵塞突起5226之前端干擾到發光部552來固定支撐發光部552，或是讓堵塞突起5226之前端不干擾到發光部552，藉由位於發光部552之稍微下方（－Z方向），防止超過發光部552之容許範圍的彎折。又，堵塞突起5226之前端形狀為任意，譬如，也可為以易於支撐曲面形狀之發光部552之方式，呈現對應到該曲面形狀之凹面形狀。Here, the height of the clogging protrusion 5226 (the length in the Z direction) may have a length range in which the front end of the clogging protrusion 5226 can be inserted into the substrate hole 556 at least when the upper cover 522 is provided with the circuit board 551, but The length of the supporting light-emitting portion 552 is more preferable. The "supportable light-emitting portion 552" indicates that the light-emitting portion 552 can prevent the connection of the light-emitting portion 552 from being bent when the light-emitting portion 552 is applied by the supporting light-emitting portion 552, and includes, for example, blocking the protrusion. The front end of the 5226 interferes with the light-emitting portion 552 to fix the light-emitting portion 552, or the front end of the blocking protrusion 5226 does not interfere with the light-emitting portion 552, and is prevented from exceeding the light-emitting portion 552 by being slightly below the light-emitting portion 552 (-Z direction). The allowable range of bending. Further, the shape of the front end of the blocking projection 5226 is arbitrary, and for example, a concave shape corresponding to the curved surface shape may be exhibited so as to easily support the curved portion of the light emitting portion 552.

（對電路基板之裝配方法） 接著，說明於本實施形態5之電路基板551，裝配上述發光部552，感光部553及屏蔽554之裝配方法。(Method of Mounting Circuit Board) Next, a method of assembling the light-emitting portion 552, the light-receiving portion 553, and the shield 554 in the circuit board 551 of the fifth embodiment will be described.

首先，簡略說明用於裝配方法之裝配用夾具5700之構造。第55圖為表示電路基板551及裝配用夾具5700之剖面圖。如該第55圖所示，裝配用夾具5700具備有：底座5710及上蓋5720，且於底座5710及底座5710之間構成可***電路基板551。First, the configuration of the jig 5700 for assembly method will be briefly explained. Fig. 55 is a cross-sectional view showing the circuit board 551 and the mounting jig 5700. As shown in FIG. 55, the mounting jig 5700 includes a base 5710 and an upper cover 5720, and an insertable circuit board 551 is formed between the base 5710 and the base 5710.

首先，說明底座5710之構造。底座5710係具備有：發光部袋子5711及感光部袋子5712。First, the configuration of the base 5710 will be described. The base 5710 is provided with a light-emitting portion bag 5711 and a light-receiving portion bag 5712.

發光部袋子5711，係可收容發光部552之大小及形狀為凹部，於發光部袋子5711收容發光部552之狀態中，發光部552及電路基板551之位置關，係最後將發光部552裝配於電路基板551之際的位置關係。於此，該發光部袋子5711之底面（＋Z方向的端面），係呈現斜面形狀，該斜面形狀係對應到發光部552之連接線的彎曲角度之角度（與發光部552之光軸平行之角度）。又，如此地，關於具有斜面形狀之理由，將於後述說明。In the light-emitting portion bag 5711, the size and shape of the light-emitting portion 552 can be accommodated as a concave portion. In the state in which the light-emitting portion bag 5711 accommodates the light-emitting portion 552, the positions of the light-emitting portion 552 and the circuit board 551 are closed, and the light-emitting portion 552 is finally attached. The positional relationship of the circuit board 551. Here, the bottom surface (the end surface in the +Z direction) of the light-emitting portion bag 5711 has a sloped shape which corresponds to the angle of the bending angle of the connecting line of the light-emitting portion 552 (the angle parallel to the optical axis of the light-emitting portion 552) ). Moreover, the reason for having a slope shape will be described later.

另外，感光部袋子5712，係可收容與感光部553一體成形之屏蔽554的大小及形狀為凹部，於感光部袋子5712收容感光部553（及屏蔽554）之狀態中，感光部553及電路基板551之位置關，係最後將感光部553裝配於電路基板551之際的位置關係。於此，該感光部袋子5712之底面（＋Z方向的端面），係呈現斜面形狀，該斜面形狀係對應到屏蔽554之傾斜角度之角度。又，如此地，關於具有斜面形狀之理由，將於後述說明。In addition, the photosensitive portion bag 5712 is configured such that the size and shape of the shield 554 integrally formed with the photosensitive portion 553 are recessed, and the photosensitive portion 553 (and the shield 554) is accommodated in the photosensitive portion bag 5712. The photosensitive portion 553 and the circuit substrate are provided. The position of 551 is the positional relationship at the time when the photosensitive portion 553 is finally mounted on the circuit board 551. Here, the bottom surface (the end surface in the +Z direction) of the photosensitive portion bag 5712 has a sloped shape which corresponds to the angle of the inclination angle of the shield 554. Moreover, the reason for having a slope shape will be described later.

於此，於該感光部袋子5712收容感光部553之狀態中，感光部553對電路基板551緊迫壓制。具體而言，於底座5710設置有施力孔5716，於該施力孔5716之內部，收納可上下滑動之滑動構件5713，且感光部袋子5712係形成於該滑動構件5713之－Z方向端部。且，於施力孔5716之底面（＋Z方向的端面），配置有彈簧5714，讓滑動構件5713朝向電路基板551方向（－Z方向）施力，藉此，讓收容於感光部袋子5712之感光部553往電路基板551對電路基板551施壓。又，讓感光部553施壓於電路基板551之具體方法，並非限於此，譬如，也可為使用橡膠等之彈性構件來取代上述彈簧5714。Here, in a state in which the photosensitive portion bag 5712 accommodates the photosensitive portion 553, the photosensitive portion 553 is pressed against the circuit board 551. Specifically, the base 5710 is provided with a biasing hole 5716. The sliding member 5713 that can slide up and down is accommodated inside the biasing hole 5716, and the photosensitive portion bag 5712 is formed at the end in the -Z direction of the sliding member 5713. Further, a spring 5714 is disposed on the bottom surface (the end surface in the +Z direction) of the urging hole 5716, and the sliding member 5713 is biased in the direction of the circuit board 551 (-Z direction), thereby accommodating the photosensitive member bag 5712. The portion 553 applies pressure to the circuit board 551 to the circuit board 551. Further, the specific method of pressing the photosensitive portion 553 on the circuit board 551 is not limited thereto, and for example, an elastic member such as rubber may be used instead of the spring 5714.

其次，說明上蓋5720之構造。上蓋5720，整體而言，係對底座5710且以其中一端部為原點而安裝成可轉動。且，於該上蓋5720之平面視之為中央部，設置稍微小於電路基板551之平面形狀的露出孔5721，於閉合上蓋5720之狀態上，透過該露出孔5721，讓電路基板551之中央部份（含上述之發光部袋子5711及感光部袋子5712之部分）可從外部露出（茲參考後述第59圖等），且藉由上蓋5720來抑制且固定電路基板551之外緣部。Next, the configuration of the upper cover 5720 will be described. The upper cover 5720 is integrally attached to the base 5710 and is rotatably mounted with one end portion as an origin. Further, the upper cover 5720 is viewed as a central portion, and an exposure hole 5721 slightly smaller than the planar shape of the circuit board 551 is provided. The upper portion of the circuit board 551 is passed through the exposure hole 5721 in a state where the upper cover 5720 is closed. (The portion including the above-described light-emitting portion bag 5711 and the light-receiving portion bag 5712) can be exposed from the outside (refer to FIG. 59 and the like described later), and the outer cover portion of the circuit board 551 can be suppressed and fixed by the upper cover 5720.

以下，說明有關使用如上述之裝配用夾具5700之裝配方法。第56圖為表示初期狀態之裝配用夾具5700之立體圖。於該狀態下，上蓋5720為開啟狀態。第57圖為表示於裝配用夾具配置有發光部552，感光部553及屏蔽554之狀態之裝配用夾具5700之立體圖。如此地，首先，於發光部袋子5711內部，收容發光部552，且於感光部袋子5712之內部收容有屏蔽554（與感光部553為一體成形之屏蔽554）。於此，關於發光部552，係事先使用其他習知之夾具（成形夾具（forming jig）等），且以既定角度為彎曲狀態下收容發光部552之連接線。又，如上述所言，發光部袋子5711之底面（＋Z方向的端面）為斜面形狀，於收容發光部552之際，雖讓發光部552以呈既定角度之方式來配置，但該底面（＋Z方向的端面）之斜面的角度，係與上述連接線之彎曲角度為對應，所以於收容發光部552之狀態中，係以沿著垂直方向之方式來配置發光部552之連接線。另外，屏蔽554之＋Z方向端部，如上述所言，為斜面形狀，感光部袋子5712之底面（＋Z方向的端面）也為對應於此該形狀之斜面形狀，所以於收容屏蔽554之際，以沿著電路基板551之方式讓屏蔽554之電路基板551側的端面（－Z方向的端面）成水平。Hereinafter, an assembly method using the assembly jig 5700 as described above will be described. Fig. 56 is a perspective view showing the assembly jig 5700 in an initial state. In this state, the upper cover 5720 is in an open state. Fig. 57 is a perspective view showing the mounting jig 5700 in which the light-emitting portion 552, the light-receiving portion 553, and the shield 554 are disposed in the mounting jig. In this manner, first, the light-emitting portion 552 is housed inside the light-emitting portion bag 5711, and a shield 554 (shield 554 integrally formed with the light-receiving portion 553) is housed inside the light-receiving portion bag 5712. Here, in the light-emitting portion 552, other conventional jigs (forming jigs, etc.) are used in advance, and the connecting line of the light-emitting portion 552 is accommodated in a bent state at a predetermined angle. In addition, as described above, the bottom surface (the end surface in the +Z direction) of the light-emitting portion bag 5711 has a sloped shape, and when the light-emitting portion 552 is housed, the light-emitting portion 552 is disposed at a predetermined angle, but the bottom surface (+Z) The angle of the slope of the end surface of the direction corresponds to the bending angle of the connecting line. Therefore, in the state in which the light-emitting portion 552 is housed, the connecting line of the light-emitting portion 552 is arranged along the vertical direction. Further, the end portion of the shield 554 in the +Z direction is a sloped shape as described above, and the bottom surface (the end surface in the +Z direction) of the photosensitive portion bag 5712 also has a slope shape corresponding to the shape, so that when the shield 554 is housed, The end surface (the end surface in the -Z direction) of the shield 554 on the side of the circuit board 551 is horizontally arranged along the circuit board 551.

接著，於裝配用夾具5700之底座5710載置電路基板551（對可裝配元件之電路基板551，以既定角度來安裝用來偵測於流入到偵測空間534之氣體是否含有被偵測物質之發光部552及感光部553之安裝步驟）。第58圖為表示載置有電路基板551之狀態下之裝配用夾具5700之立體圖。於此，於裝配用夾具5700，形成有定位用突起5715，且讓該定位用突起5715以貫通被形成於電路基板551之定位用孔557之方式，藉由載置電路基板551可獨特地確定對底座5710之電路基板551的位置。此時，於設置於電路基板551之各通孔上插通發光部552，屏蔽554及感光部553之連接線。Next, the circuit board 551 is placed on the base 5710 of the mounting jig 5700 (the circuit board 551 of the mountable component is mounted at a predetermined angle for detecting whether the gas flowing into the detection space 534 contains the detected substance. Installation steps of the light-emitting portion 552 and the light-receiving portion 553). Fig. 58 is a perspective view showing the mounting jig 5700 in a state in which the circuit board 551 is placed. Here, in the mounting jig 5700, the positioning protrusions 5715 are formed, and the positioning protrusions 5715 are uniquely defined by the mounting circuit board 551 so as to penetrate the positioning holes 557 formed in the circuit board 551. The position of the circuit board 551 of the base 5710. At this time, the light-emitting portion 552 is inserted into each of the through holes provided in the circuit board 551, and the connection line between the shield 554 and the light-receiving portion 553 is inserted.

其次，讓上蓋5720為閉合狀態且固定電路基板551。第59圖為表示讓上蓋5720為閉合狀態之裝配用夾具5700之立體圖。又，為了進一歩不讓電路基板551搖動，也可利用習知之銷(pin)等來抑制固定上蓋5700。Next, the upper cover 5720 is brought into a closed state and the circuit board 551 is fixed. Fig. 59 is a perspective view showing the jig 5700 for attaching the upper cover 5720 to the closed state. Further, in order to prevent the circuit board 551 from being shaken, it is also possible to suppress the fixing of the upper cover 5700 by a pin or the like.

最後，於第59圖所示狀態中，對電路基板551電氣性裝配發光部552，感光部553及屏蔽554（於安裝步驟中，讓安裝於電路基板551之發光部552及感光部553，以維持既定角度（安裝時之角度）之狀態下，對電路基板551電氣性裝配之裝配步驟）。又，如圖所示，藉由上蓋5720之露出孔5721而讓部分之電路基板551露出，所以即使上蓋5720為閉合狀態也可直接於電路基板551進行焊接（soldering）。具體而言，首先，於被設置於電路基板551之基板孔556，插通光軸調整銷5701（茲參考第55圖），且讓發光部552往發光部袋子5711之＋Z方向端面抑制且固定之狀態下，對電路基板551焊接且裝配從電路基板551之通孔突出之發光部552之連接線。如此地，發光部552，藉由以光軸調整銷5701產生緊迫壓制之力量，於發光部袋子5711內部利用抑制固定成傾斜方向，而獨特地決定設置位置及角度。接著，對電路基板551焊接且裝配從電路基板551之通孔突出之感光部553之連接線。又，感光部553，如上述所言，藉由往－Z方向之施力對電路基板551抑制固定，而獨特地決定設置位置及角度。Finally, in the state shown in FIG. 59, the light-emitting portion 552, the light-receiving portion 553, and the shield 554 are electrically mounted on the circuit board 551 (in the mounting step, the light-emitting portion 552 and the light-receiving portion 553 are mounted on the circuit board 551 to The assembly step of electrically assembling the circuit board 551 in a state where the predetermined angle (the angle at the time of mounting) is maintained. Further, as shown in the drawing, a part of the circuit board 551 is exposed by the exposure hole 5721 of the upper cover 5720. Therefore, even if the upper cover 5720 is in a closed state, soldering can be performed directly on the circuit board 551. Specifically, first, the optical axis adjustment pin 5701 is inserted into the substrate hole 556 provided in the circuit board 551 (refer to FIG. 55), and the light-emitting portion 552 is restrained and fixed to the end surface of the light-emitting portion bag 5711 in the +Z direction. In the state of the circuit board 551, the connection line of the light-emitting portion 552 protruding from the through hole of the circuit board 551 is attached. In this manner, the light-emitting portion 552 uniquely determines the installation position and angle by suppressing the fixing of the inside of the light-emitting portion bag 5711 by the force of the pressing force by the optical axis adjustment pin 5701. Next, the circuit board 551 is soldered and the connection line of the light-receiving portion 553 protruding from the through hole of the circuit board 551 is mounted. Further, as described above, the light-receiving portion 553 uniquely determines the installation position and angle by suppressing the fixing of the circuit board 551 by the biasing force in the -Z direction.

以上，將完成對電路基板551，裝配上述之發光部552，感光部553及屏蔽554之裝配方法之說明。且，以覆蓋電路基板551及裝配於電路基板551之發光部552及感光部553之方式，設置被***於電路基板551及偵測空間534之間的偵測部本體504（覆蓋手段設置步驟。茲參考第35圖等），利用於殼體502之間收納有各零件，即可製造警報裝置5100。As described above, the description will be given of a method of assembling the above-described light-emitting portion 552, the light-receiving portion 553, and the shield 554 to the circuit board 551. Further, the detecting unit body 504 inserted between the circuit board 551 and the detecting space 534 is provided so as to cover the circuit board 551 and the light emitting unit 552 and the light receiving unit 553 mounted on the circuit board 551 (the covering means setting step). Referring to Fig. 35 and the like, the alarm device 5100 can be manufactured by accommodating the components between the casings 502.

（實施形態5之效果） 如此地，藉由本實施形態5的話，由於偵測部本體504不會干擾到電路基板551，發光部552及感光部553，所以可省略於偵測部本體504，從設定發光部552及感光部553之後，將電路基板551覆蓋到偵測部本體504上且於電路基板551之通孔同時***發光部552及感光部553之連接線的作業，且可簡化發光部552及感光部553之裝配作業，同時，不需於偵測部本體504設置用來安裝發光部552及感光部553之機構，且可簡化偵測部本體504之機構，進而可提高警報裝置5100之生產性。(Effect of the fifth embodiment) As described in the fifth embodiment, since the detecting unit body 504 does not interfere with the circuit board 551, the light emitting unit 552, and the light receiving unit 553, the detecting unit body 504 can be omitted. After the light-emitting portion 552 and the light-receiving portion 553 are set, the circuit board 551 is placed on the detecting portion main body 504, and the connection between the light-emitting portion 552 and the light-receiving portion 553 is simultaneously inserted into the through hole of the circuit board 551, and the light-emitting portion can be simplified. The assembly operation of the 552 and the photosensitive portion 553 does not require the mechanism for mounting the light-emitting portion 552 and the light-receiving portion 553 on the detecting portion body 504, and the mechanism of the detecting portion body 504 can be simplified, thereby improving the alarm device 5100. Productive.

另外，偵測手段，具備有感光部553，且由於讓屏蔽554與感光部553一體性形成，所以可簡化感光部553及屏蔽554之裝配作業，同時不需於偵測部本體504設置用來將感光部553及屏蔽554安裝於偵測部本體504之機構，且可簡化偵測部本體504之機構，進而可提高警報裝置5100之生產性。Further, the detecting means includes the light-receiving portion 553, and since the shield 554 and the light-receiving portion 553 are integrally formed, the assembling operation of the photosensitive portion 553 and the shield 554 can be simplified, and the detecting portion body 504 is not required to be provided. The mechanism in which the photosensitive portion 553 and the shield 554 are attached to the detecting portion body 504 can simplify the mechanism of the detecting portion body 504, thereby improving the productivity of the alarm device 5100.

另外，於偵測部本體504之外緣部，由於具備有用來促進讓氣體往偵測空間534流入之凸緣部541，所以可增加往偵測空間534之氣體流入量，且可以提高偵測精密度。In addition, since the flange portion 541 for facilitating the inflow of gas into the detection space 534 is provided at the outer edge portion of the detecting portion main body 504, the amount of gas flowing into the detecting space 534 can be increased, and the detection can be improved. Precision.

另外，由於讓始終進行來自電源部之應力的電池固定彈簧548與從外部無法辨識出之偵測部本體504為一體性形成，所以如殼體502般，相較設置於從外部可辨識出之機構的情況，不會讓藉由該應力所產生之變形如此顯目且可防止外觀不良。Further, since the battery fixing spring 548 which always receives the stress from the power supply unit is integrally formed with the detecting portion main body 504 which is not recognized from the outside, it is disposed outside the casing 502 as compared with the housing 502. In the case of the mechanism, the deformation caused by the stress is not so conspicuous and the appearance is poor.

另外，由於讓用來收納連接到電路基板551之揚聲氣之揚聲器收納部545與偵測部本體504為一體性形成，所以於與偵測部本體504之中的電路基板551為相同面側，設置輸出手段，且簡化對揚聲器之電路基板551之連接，進而可提高警報裝置5100之生產性。In addition, since the speaker housing portion 545 for accommodating the speaker sound connected to the circuit board 551 is integrally formed with the detecting unit body 504, it is on the same surface side as the circuit board 551 in the detecting unit body 504. The output means is provided, and the connection to the circuit board 551 of the speaker is simplified, and the productivity of the alarm device 5100 can be improved.

另外，於電路基板551，由於具備可插通光軸調整銷5701之基板孔556，所以可藉由插通光軸調整銷5701而抑制固定發光部552之極容易的方法來易於確定發光部552之安裝角度，進而可提高警報裝置5100之生產性。Further, since the circuit board 551 includes the substrate hole 556 through which the optical axis adjustment pin 5701 can be inserted, it is possible to easily determine the light-emitting portion 552 by inserting the optical axis adjustment pin 5701 and suppressing the extremely easy method of fixing the light-emitting portion 552. The mounting angle further increases the productivity of the alarm device 5100.

另外，由於在殼體502具備有用來堵住基板孔556之堵塞突起5226，所以可防止讓發光部552之光線從基板孔556回繞而於感光部553上感光所導致誤偵測之情況發生，且可提高偵測精密度。In addition, since the housing 502 is provided with a blocking protrusion 5226 for blocking the substrate hole 556, it is possible to prevent the light of the light-emitting portion 552 from being rewound from the substrate hole 556 and being erroneously detected by the photosensitive portion 553. And can improve the detection precision.

另外，堵塞突起5226，由於可支撐發光部552，所以可防止因某種原因對發光部552施加外力時而改變發光部552之角度進且降低偵測精密度之情況發生。Further, since the clogging protrusion 5226 can support the light-emitting portion 552, it is possible to prevent the angle of the light-emitting portion 552 from changing and reducing the detection precision when an external force is applied to the light-emitting portion 552 for some reason.

另外，偵測部本體504由於具備有發光孔5436及感光孔5437，所以可抑制於偵測部本體504覆蓋電路基板551而讓塵埃塵積於電路基板551，同時可構成藉由發光孔5436及感光孔5437而不阻礙發光部552及感光部553之光軸的構造。Further, since the detecting unit body 504 includes the light-emitting holes 5436 and the light-receiving holes 5437, it is possible to prevent the detecting unit body 504 from covering the circuit board 551 and allowing dust to collect on the circuit board 551, and the light-emitting holes 5436 and The photosensitive hole 5437 does not hinder the configuration of the optical axes of the light-emitting portion 552 and the light-receiving portion 553.

另外，於發光孔5436及感光孔5437周圍，由於具備有朝向與偵測空間534為反向側且下凹之凹槽部5434，所以可防止藉由讓塵埃塵積於該凹槽部5434而讓塵埃大量塵積於偵測部本體504上面，且也可防止讓塵積於偵測部本體504當中之發光孔5436或感光孔5437周圍的塵埃因位於發光軸上或感光軸上而降低偵測精密度之形態發生。In addition, since the concave portion 5434 which is opposite to the detection space 534 and which is recessed is provided around the light-emitting hole 5436 and the light-receiving hole 5437, dust can be prevented from being accumulated in the groove portion 5434 by dust. The dust is accumulated on the detecting unit body 504, and the dust around the light-emitting hole 5436 or the light-receiving hole 5437 in the detecting portion body 504 is prevented from being lowered on the light-emitting axis or the photosensitive shaft. The form of precision is measured.

另外，以豎立於發光孔5436或感光孔5437周圍之方式來配置，且具備覆蓋發光部552或感光部553周圍之遮光框部435，所以可防止讓來自發光部552之光線伴隨著不透過偵測空間534而直接於感光部553感光而導致誤偵測之情況發生，同時也可防止讓塵積於偵測部本體504之塵埃從偵測部本體504通過發光孔5436或感光孔5437掉落到發光部552或感光部553而塵積於發光部552或感光部553之表面，導致降低偵測精密度之情況發生。In addition, it is disposed so as to stand around the light-emitting hole 5436 or the light-receiving hole 5437, and has a light-shielding frame portion 435 covering the light-emitting portion 552 or the light-receiving portion 553. Therefore, it is possible to prevent the light from the light-emitting portion 552 from being accompanied by the opaque detection. The measurement space 534 is directly exposed to the photosensitive portion 553 to cause a false detection, and the dust accumulated in the detecting portion body 504 is prevented from falling from the detecting portion body 504 through the light emitting hole 5436 or the photosensitive hole 5437. When the light emitting portion 552 or the light receiving portion 553 is deposited on the surface of the light emitting portion 552 or the light receiving portion 553, the detection precision is lowered.

另外，對電路基板551安裝且電氣性裝配發光部552及感光部553之後，由於設置有偵測部本體504，所以於偵測部本體504設定發光部552及感光部553之後，可省略將電路基板551覆蓋到該偵測部本體504且於電路基板551之通孔同持***發光部552及感光部553之連接線之作業，同時，可簡化發光部552及感光部553之裝配作業，且不需於偵測部本體504設置用來安裝發光部552及感光部553之機構，且可簡化偵測部本體504之機構，進而可提高警報裝置5100之生產性。Further, after the light-emitting portion 552 and the light-receiving portion 553 are mounted and electrically mounted on the circuit board 551, since the detecting portion main body 504 is provided, after the light-emitting portion 552 and the light-receiving portion 553 are set in the detecting portion main body 504, the circuit can be omitted. The substrate 551 covers the detecting portion body 504 and the through hole of the circuit board 551 is inserted into the connecting line of the light emitting portion 552 and the light receiving portion 553, and the assembly work of the light emitting portion 552 and the light receiving portion 553 can be simplified. The mechanism for mounting the light-emitting portion 552 and the light-receiving portion 553 is not required to be provided in the detecting portion main body 504, and the mechanism of the detecting portion body 504 can be simplified, and the productivity of the alarm device 5100 can be improved.
