Description
本發明係關於一種調整入射光量之光圈裝置及具備其之攝影機。 The present invention relates to an aperture device for adjusting the amount of incident light and a camera provided therewith.
於包含監視攝影機之各種攝影機中，組入有調整自外部入射之光之量(以下，記作「入射光量」)的光圈裝置。光圈裝置係藉由改變存在於入射光之光路上的光圈開口之大小而調整(精確化)入射光量者。作為光圈裝置之結構，存在藉由光圈構件之移動而進行光量調整者。具體而言，作為光圈構件之一例，公知有使用一對光圈葉片者(例如，參照專利文獻1)。 In a variety of cameras including a surveillance camera, an aperture device that adjusts the amount of light incident from the outside (hereinafter referred to as "incident light amount") is incorporated. The aperture device adjusts (accurates) the amount of incident light by changing the size of the aperture opening existing on the optical path of the incident light. As the structure of the aperture device, there is a person who adjusts the amount of light by the movement of the diaphragm member. Specifically, as an example of the diaphragm member, a pair of aperture blades are known (for example, refer to Patent Document 1).
又，於習知技術中，係利用馬達作為用以使光圈構件移動之驅動源。具體而言，成為如下結構，即，將旋轉驅動之驅動馬達之驅動力經由動力傳遞機構傳遞至作動構件，藉由該作動構件而使光圈構件移動。又，作為動力傳遞機構，公知有利用齒輪傳遞機構者(例如，參照專利文獻2)。 Further, in the prior art, a motor is used as a driving source for moving the diaphragm member. Specifically, the driving force of the drive motor that is rotationally driven is transmitted to the actuating member via the power transmission mechanism, and the diaphragm member is moved by the actuating member. Further, as the power transmission mechanism, a gear transmission mechanism is known (for example, refer to Patent Document 2).

然而，於利用齒輪傳遞機構之光圈裝置中，存在如下問題。 However, in the aperture device using the gear transmission mechanism, there are the following problems.
即，雖然於驅動馬達與作動構件之間設置有構成齒輪傳遞機構之數個齒輪，但於使該等齒輪嚙合時，有損傷齒輪之齒之虞。具體而言，在使安裝於驅動馬達之旋轉軸的驅動齒輪嚙合於從動齒輪之情形時，有時會因齒輪彼此之碰撞而損傷齒輪之齒。其理由在於在習知之光圈裝置中係成為如下構成，即，使驅動齒輪自沿旋轉自如地支撐從動齒輪之支軸的方向(縱方向)接近從動齒輪，從而使齒輪彼此嚙合。 That is, although a plurality of gears constituting the gear transmission mechanism are provided between the drive motor and the actuating member, when the gears are meshed, the teeth of the gear are damaged. Specifically, when the drive gear attached to the rotating shaft of the drive motor is meshed with the driven gear, the teeth of the gear may be damaged by the collision of the gears. The reason for this is that, in the conventional aperture device, the drive gear is brought into close contact with the driven gear in the direction (longitudinal direction) in which the support shaft of the driven gear is rotatably supported, and the gears mesh with each other.
若進一步詳細敍述，於光圈裝置之組裝步驟中，首先，使預先確定之既定個數之從動齒輪相互嚙合，將從動齒輪分別安裝於所對應之支軸。其後，使驅動齒輪嚙合於預先確定之一個從動齒輪。此時，需要將驅動馬達之旋轉軸朝下方而使驅動齒輪與從動齒輪相對向。如此，當使驅動齒輪自沿從動齒輪之支軸之方向接近從動齒輪時，驅動齒輪會成為驅動馬達之背後，故而難以自外部目視確認驅動齒輪與從動齒輪之位置關係。因此，實際上進行組裝作業之作業者摸索著使驅動齒輪與從動齒輪嚙合。其結果，於摸索著使齒輪彼此嚙合時，有齒與齒相互碰撞而損傷之虞。若齒輪上實際上有損傷，則使齒輪旋轉時之阻抗會變大。因此，會引起驅動馬達之最低動作電壓上升等問題。因此，為了不損傷齒輪之齒，作業者必須謹慎地作業。 As will be described in more detail, in the assembly step of the aperture device, first, a predetermined number of driven gears are engaged with each other, and the driven gears are respectively attached to the corresponding support shafts. Thereafter, the drive gear is engaged with a predetermined one of the driven gears. At this time, it is necessary to face the rotation shaft of the drive motor so that the drive gear and the driven gear face each other. As described above, when the drive gear approaches the driven gear from the direction of the support shaft of the driven gear, the drive gear becomes the rear of the drive motor, so that it is difficult to visually confirm the positional relationship between the drive gear and the driven gear from the outside. Therefore, the operator who actually performs the assembly work explores the meshing of the drive gear and the driven gear. As a result, when the gears are meshed with each other, the teeth and the teeth collide with each other to cause damage. If there is actually damage on the gear, the impedance will increase as the gear rotates. Therefore, problems such as an increase in the minimum operating voltage of the drive motor are caused. Therefore, in order not to damage the teeth of the gear, the operator must work cautiously.
本發明之主要目的在於提供一種在使用驅動齒輪與從動齒輪將驅動馬達之驅動力傳遞至作動構件之光圈裝置中，於使驅動齒輪與從動齒輪嚙合之情形時，可不損傷齒輪之齒而使齒輪彼此簡單地嚙合的技術。 SUMMARY OF THE INVENTION A primary object of the present invention is to provide an aperture device for transmitting a driving force of a driving motor to an actuating member using a driving gear and a driven gear, so as not to damage the teeth of the gear when the driving gear is meshed with the driven gear.

<3.光圈裝置之組裝步驟之概要> <3. Outline of assembly procedure of aperture device>
光圈裝置1之組裝步驟大致分為將光圈驅動部5安裝於光圈基板2之步驟、及將光圈構件3安裝於光圈基板2之步驟。 The assembly procedure of the aperture device 1 is roughly divided into a step of attaching the diaphragm driving unit 5 to the diaphragm substrate 2 and a step of attaching the diaphragm member 3 to the diaphragm substrate 2.
於將光圈驅動部5安裝於光圈基板2之步驟中，首先，如圖9所示，將作動構件6安裝於齒輪盒部17內。其次，如圖10~圖12所示，於光圈基板2之齒輪盒部17依序安裝減速齒輪7、減速齒輪8及減速齒輪9。 In the step of attaching the diaphragm driving unit 5 to the diaphragm substrate 2, first, as shown in FIG. 9, the operating member 6 is attached to the gear case portion 17.

At this time, the drive gear 65 is fixed to the rotary shaft 11a so that the drive gear 65 rotates integrally with the rotary shaft 11a. Next, the drive motor 11 is attached to the holder member 12. Next, as shown in FIG. 14, the holder member 12 to which the drive motor 11 is attached is attached to the outer casing member 10. At this time, the holder member 12 is in a state of being stacked on the outer casing member 10. Further, the drive gear 65 may be attached to the rotating shaft 11a after the drive motor 11 is attached to the holder member 12.
於將光圈構件3安裝於光圈基板2之步驟中，在光圈基板2之下表面側依序安裝光圈葉片41與光圈葉片42。此時，使光圈葉片41之卡合孔45卡合於作動構件6之卡合銷51a，並且使光圈葉片 42之卡合孔48卡合於作動構件6之卡合銷51b。又，使光圈葉片41之導向溝44a、44b、44c分別卡合於所對應之光圈基板2之導銷38a、38c、38d。同樣地，使光圈葉片42之導向溝47a、47b、47c分別卡合於所對應之光圈基板2之導銷38a、38b、38c。 In the step of attaching the diaphragm member 3 to the diaphragm substrate 2, the diaphragm blades 41 and the diaphragm blades 42 are sequentially attached to the lower surface side of the diaphragm substrate 2.

Further, the engaging pins 51a and 51b of the actuating member 6 are disposed in the escape holes 49a and 49b of the shielding member 4.
<4.光圈裝置之動作> <4. Action of aperture device>
光圈裝置1隨著驅動馬達11之驅動而動作。即，若驅動馬達11驅動，則其旋轉驅動力自驅動齒輪65經由減速齒輪9、減速齒輪8及減速齒輪7而傳遞至作動齒輪52。因此，作動構件6隨著驅動馬達11之驅動而旋轉。 The aperture device 1 operates in accordance with the driving of the drive motor 11. In other words, when the drive motor 11 is driven, the rotational driving force is transmitted from the drive gear 65 to the actuating gear 52 via the reduction gear 9, the reduction gear 8, and the reduction gear 7. Therefore, the actuating member 6 rotates as the drive motor 11 is driven.
又，若作動構件6旋轉，則卡合於作動構件6之卡合銷51a、51b的光圈葉片41、42沿光圈基板2之長度方向而直線地移動。此時，光圈葉片41移動之方向與光圈葉片42移動之方向成為相互相反之方向。又，光圈開口之大小係根據光圈葉片41、42所移動之方向而變化。因此，可藉由改變驅動馬達11之旋轉量及旋轉方向，而調整光圈開口之大小。 Further, when the actuating member 6 rotates, the diaphragm blades 41 and 42 that are engaged with the engaging pins 51a and 51b of the actuating member 6 linearly move in the longitudinal direction of the diaphragm substrate 2. At this time, the direction in which the diaphragm blades 41 move and the direction in which the diaphragm blades 42 move are opposite directions. Further, the size of the aperture opening changes depending on the direction in which the aperture blades 41, 42 move. Therefore, the size of the aperture opening can be adjusted by changing the amount of rotation and the direction of rotation of the drive motor 11.

The upper end covers the outer casing member 10. At this time, the outer casing member 10 is positioned with respect to the gear case portion 17 by fitting the three positioning holes 55a, 55b, 55c to the corresponding protrusions 22, 23, and 24, respectively. Further, by fitting the three support holes 57a, 57b, 57c provided on the back side of the outer casing member 10 to the small diameter portions 29a, 30a, 31a of the corresponding support shafts 29, 30, 31, the outer casing is used.

(驅動馬達11之安裝) (Installation of the drive motor 11)
於將驅動馬達11安裝於固定器構件12之情形時，使2個凸緣部66a、66b分別對準所對應之夾持片71a、71b之位置，而將驅動馬達11按壓於固定器構件12之馬達安裝面76。此時，使驅動馬達11之外 周面沿馬達安裝導引部75a、75b。又，將夾持片71a勾在一凸緣部66a之凹狀部，並且將夾持片71b勾在另一凸緣部66b之凹狀部。藉此，驅動馬達11藉由一對夾持片71a、71b而固定於固定器構件12。 When the drive motor 11 is attached to the holder member 12, the two flange portions 66a, 66b are respectively aligned with the positions of the corresponding holding pieces 71a, 71b, and the drive motor 11 is pressed against the holder member 12. Motor mounting surface 76. At this time, the drive motor 11 is made The circumferential surface is provided with guide portions 75a, 75b along the motor. Further, the holding piece 71a is hooked to the concave portion of the flange portion 66a, and the holding piece 71b is hooked to the concave portion of the other flange portion 66b. Thereby, the drive motor 11 is fixed to the holder member 12 by the pair of holding pieces 71a and 71b.
(固定器構件12之安裝) (Installation of the holder member 12)
於將固定器構件12安裝於外殼構件10之情形時，如上述圖7所示，使驅動馬達11之驅動齒輪65朝下方，於此狀態下如上述圖14所示，將固定器構件12安裝於外殼構件10。具體而言，係以如下順序進行安裝。再者，此處除參照上述圖14以外，亦參照表示外殼構件10之詳細情況之上述圖6與表示固定器構件12之詳細情況之上述圖8而進行說明。 When the holder member 12 is attached to the outer casing member 10, as shown in FIG. 7 described above, the drive gear 65 of the drive motor 11 is directed downward, and in this state, the holder member 12 is mounted as shown in FIG. 14 described above. The outer casing member 10. Specifically, the installation is performed in the following order. Here, in addition to the above-described FIG. 14 , the above-described FIG. 6 showing the details of the outer casing member 10 and the above-described FIG. 8 showing the details of the anchor member 12 will be described.
首先，於2個卡止片70a、70b分別與所對應之被卡止部58a、58b相對向之狀態下，將固定器構件12載置於外殼構件10之上。此時，使固定器構件12之設置面77a接觸於固定器構件12之支承面20a，並且使固定器構件12之設置面77b接觸於固定器構件12之支承面20b。其次，於使該等面彼此接觸之狀態下，使固定器構件12沿支承面20a、20b移動(滑動)。此時，將2個卡止片70a、70b分別***至所對應之被卡止部58a、58b。亦即，使固定器構件12自橫方向滑入至外殼構件10，藉此以卡入方式將固定器構件12安裝於外殼構件10。 First, the holder member 12 is placed on the outer casing member 10 in a state in which the two locking pieces 70a and 70b face the corresponding engaged portions 58a and 58b, respectively. At this time, the installation surface 77a of the holder member 12 is brought into contact with the support surface 20a of the holder member 12, and the installation surface 77b of the holder member 12 is brought into contact with the support surface 20b of the holder member 12. Next, the holder member 12 is moved (slid) along the support faces 20a and 20b in a state where the faces are brought into contact with each other. At this time, the two locking pieces 70a and 70b are inserted into the corresponding locked portions 58a and 58b, respectively. That is, the holder member 12 is slid into the outer casing member 10 from the lateral direction, whereby the anchor member 12 is attached to the outer casing member 10 in a snap-fit manner.
藉此，如上述圖12所示，安裝於驅動馬達11之旋轉軸11a的驅動齒輪65成為如下狀態，即，於該驅動齒輪65之中心位於X軸上之狀態下與減速齒輪9之大徑齒輪部9a嚙合。於該狀態下，減速齒輪7之中心與減速齒輪9之中心係配置於與光圈基板2之短邊方向(Y軸方向)平行的軸線J1上，在與其相同之軸線J1上配置有驅動齒輪 65之中心。藉此，可於有限空間內以較高安裝密度配置數個齒輪。 As a result, as shown in FIG. 12 described above, the drive gear 65 attached to the rotary shaft 11a of the drive motor 11 is in a state in which the large diameter of the reduction gear 9 is in a state where the center of the drive gear 65 is located on the X-axis. The gear portion 9a is meshed. In this state, the center of the reduction gear 7 and the center of the reduction gear 9 are disposed on the axis J1 parallel to the short-side direction (Y-axis direction) of the diaphragm substrate 2, and the drive gear is disposed on the same axis J1. The center of 65. Thereby, several gears can be arranged with a high installation density in a limited space.
當安裝上述固定器構件12時，固定器構件12於外殼構件10上移動(滑動)之方向係成為沿外殼構件10之支承面20a、20b且與Y軸方向平行的方向。因此，驅動馬達11之驅動齒輪65係自沿外殼構件10之支承面20a、20b之橫方向(Y方向)接近減速齒輪9的大徑齒輪部9a。又，藉由自橫方向(Y方向)之滑入而使2個卡止片70a、70b分別鈎在所對應之被卡止部58a、58b，藉此，使固定器構件12以卡入方式固定於外殼構件10。又，於固定器構件12之移動方向，藉由使設置於固定器構件12之2個碰觸部79a、79b碰觸於與其相對應的外殼構件10之2個被碰觸部64a、64b(參照圖6)，而相對於外殼構件10定位固定器構件12。又，藉由將***部78a***至按壓部63a，並且將***部78b***至按壓部63b，可抑制固定器構件12之浮起。 When the above-described holder member 12 is mounted, the direction in which the holder member 12 moves (slides) on the outer casing member 10 becomes a direction parallel to the support faces 20a, 20b of the outer casing member 10 and in the Y-axis direction. Therefore, the drive gear 65 of the drive motor 11 approaches the large-diameter gear portion 9a of the reduction gear 9 from the lateral direction (Y direction) of the support faces 20a, 20b of the outer casing member 10. Further, by sliding in from the lateral direction (Y direction), the two locking pieces 70a and 70b are respectively hooked to the corresponding engaged portions 58a and 58b, whereby the holder member 12 is engaged. It is fixed to the outer casing member 10. Further, in the moving direction of the holder member 12, the two contact portions 79a, 79b provided on the holder member 12 are brought into contact with the two contact portions 64a, 64b of the outer casing member 10 corresponding thereto ( Referring to Figure 6), the anchor member 12 is positioned relative to the outer casing member 10. Further, by inserting the insertion portion 78a into the pressing portion 63a and inserting the insertion portion 78b into the pressing portion 63b, the floating of the holder member 12 can be suppressed.
若以如上方式安裝固定器構件12，則驅動馬達11之驅動齒輪65會於齒輪收容部60之連通部61嚙合於減速齒輪9之大徑齒輪部9a。此時，如圖16所示，驅動齒輪65係以沿軸線J1向減速齒輪9之中心移動之方式而構成。 When the holder member 12 is attached as described above, the drive gear 65 of the drive motor 11 meshes with the large-diameter gear portion 9a of the reduction gear 9 at the communication portion 61 of the gear housing portion 60. At this time, as shown in FIG. 16, the drive gear 65 is configured to move toward the center of the reduction gear 9 along the axis J1.
如圖17所示，藉由以上組裝步驟而成為的狀態：驅動馬達11之驅動齒輪65嚙合於減速齒輪9之大徑齒輪部9a，並且減速齒輪9之小徑齒輪部9b嚙合於減速齒輪8之大徑齒輪部8a。又，成為減速齒輪8之小徑齒輪部8b嚙合於減速齒輪7之大徑齒輪部7a，並且減速齒輪7之小徑齒輪部7b嚙合於作動構件6之作動齒輪52的狀態。因此，若驅動馬達11驅動，則該驅動力會經由齒輪傳遞機構傳遞至作動構件6。具體而言，若驅動馬達11驅動，則其驅動力會自驅動齒輪65經由減速齒輪9、減速齒輪8及減速齒輪7傳遞至作動齒輪52。因 此，如上所述，藉由伴隨驅動馬達11之驅動之作動構件6之旋轉動作，可調整光圈葉片41、42所形成之光圈開口之大小。 As shown in FIG. 17, the drive gear 65 of the drive motor 11 is meshed with the large-diameter gear portion 9a of the reduction gear 9, and the small-diameter gear portion 9b of the reduction gear 9 is meshed with the reduction gear 8 as shown in FIG. The large diameter gear portion 8a. Further, the small-diameter gear portion 8b serving as the reduction gear 8 meshes with the large-diameter gear portion 7a of the reduction gear 7, and the small-diameter gear portion 7b of the reduction gear 7 is engaged with the actuator gear 52 of the actuator member 6. Therefore, when the drive motor 11 is driven, the driving force is transmitted to the actuating member 6 via the gear transmission mechanism. Specifically, when the drive motor 11 is driven, the driving force is transmitted from the drive gear 65 to the actuating gear 52 via the reduction gear 9, the reduction gear 8, and the reduction gear 7. because Thus, as described above, the size of the aperture opening formed by the aperture blades 41, 42 can be adjusted by the rotation of the actuator member 6 driven by the drive motor 11.
<6.本實施形態之效果> <6. Effect of this embodiment>
根據本發明之實施形態之光圈裝置1，可獲得如下效果。 According to the aperture device 1 of the embodiment of the present invention, the following effects can be obtained.
即，於本實施形態中，成為如下構成，即，藉由利用自橫方向之滑入之卡入方式將安裝有驅動馬達11之固定器構件12安裝於外殼構件10，而使驅動齒輪65嚙合於減速齒輪9之大徑齒輪部9a。於該構成中，使驅動齒輪65接觸於減速齒輪9時所產生之力係作用於使驅動齒輪65及減速齒輪9旋轉之方向。因此，可不損傷相互之齒，而使減速齒輪9與驅動齒輪65順利地嚙合。因此，可避免起因於齒輪之損傷之問題例如驅動馬達11之動作電壓之上升。 In other words, in the present embodiment, the holder member 12 to which the drive motor 11 is attached is attached to the outer casing member 10 by the snap-in method of sliding in from the lateral direction, and the drive gear 65 is meshed. The large diameter gear portion 9a of the reduction gear 9 is provided. In this configuration, the force generated when the drive gear 65 comes into contact with the reduction gear 9 acts on the direction in which the drive gear 65 and the reduction gear 9 rotate. Therefore, the reduction gear 9 and the drive gear 65 can be smoothly meshed without damaging the mutual teeth. Therefore, it is possible to avoid a problem caused by the damage of the gear, for example, an increase in the operating voltage of the drive motor 11.
圖18係表示當使於齒輪之齒有損傷之製品(光圈裝置)與無損傷之製品動作，分別測定驅動馬達之最低動作電壓時之結果的圖。圖18之(A)表示有損傷之情形時之測定結果，(B)表示無損傷之情形時之測定結果。自圖可知，於有損傷之製品中，與馬達單體之最低動作電壓相比，電壓變化量之最大值為0.6 V，最小值為0.3 V，平均值為0.42 V。與此相對，於無損傷之製品中，與馬達單體之最低動作電壓相比，電壓變化量之最大值為0.2 V，最小值為0.0 V，平均值為0.04 V。其中，若以電壓變化量之平均值進行比較，可知，有損傷之情形時驅動馬達之最低動作電壓之變化量(增加量)較大，為無損傷之情形時驅動馬達之最低動作電壓之變化量(增加量)的10倍。自以上測定結果可知，齒輪之損傷會較大地影響驅動馬達之動作電壓。因此，只要如上述構成之光圈裝置1般可不損傷齒輪而組裝，便可有效地避免最低動作電壓之上升。 Fig. 18 is a view showing the results of measuring the lowest operating voltage of the drive motor when the product (iris device) having damage to the teeth of the gear and the non-damaged product are operated. Fig. 18(A) shows the measurement results in the case of damage, and (B) shows the measurement results in the case of no damage. As can be seen from the figure, in the damaged product, the maximum value of the voltage change is 0.6 V, the minimum value is 0.3 V, and the average value is 0.42 V, compared with the minimum operating voltage of the motor unit. On the other hand, in the non-damaged product, the maximum value of the voltage change is 0.2 V, the minimum value is 0.0 V, and the average value is 0.04 V, compared with the lowest operating voltage of the motor unit. In the case where the average value of the voltage change is compared, it can be seen that the amount of change (increased amount) of the lowest operating voltage of the drive motor is large in the case of damage, and the change in the minimum operating voltage of the drive motor in the case of no damage. 10 times the amount (increase). It can be seen from the above measurement results that the damage of the gear greatly affects the operating voltage of the drive motor. Therefore, as long as the optical disk device 1 configured as described above can be assembled without damaging the gear, the increase in the minimum operating voltage can be effectively avoided.
又，於本實施形態中，成為利用使用被卡止部58a、58b與卡止片70a、70b之卡入方式將固定器構件12安裝於外殼構件10之構成。因此，可藉由卡入方式一面導引固定器構件12之移動方向，一面使減速齒輪9與驅動齒輪65嚙合。因此，無需如習知般作業者摸索著謹慎地使齒輪彼此嚙合，並且可實現組裝作業之簡易化與縮短時間。 Moreover, in the present embodiment, the holder member 12 is attached to the outer casing member 10 by the engagement of the locked portions 58a and 58b and the locking pieces 70a and 70b. Therefore, the reduction gear 9 can be meshed with the drive gear 65 while guiding the moving direction of the holder member 12 by the engagement method. Therefore, it is not necessary for the operator to fumblefully engage the gears with each other as is conventional, and it is possible to simplify the assembly work and shorten the time.
又，於本實施形態中，係採用藉由使支軸29、30、31之小徑部29a、30a、31a嵌合於設置在固定器構件12之3個支撐孔57a、57b、57c，而支撐支軸29、30、31的構成。因此，於齒輪傳遞機構動作時，可抑制各個支軸29、30、31之傾斜及振動，從而可使各個減速齒輪7、8、9順利地旋轉。進而，藉由該構成，亦可阻止減速齒輪7、8、9自支軸29、30、31脫落。 Further, in the present embodiment, the small diameter portions 29a, 30a, and 31a of the support shafts 29, 30, and 31 are fitted to the three support holes 57a, 57b, and 57c provided in the holder member 12. The structure of the support shafts 29, 30, 31 is supported. Therefore, when the gear transmission mechanism operates, the inclination and vibration of the respective support shafts 29, 30, and 31 can be suppressed, and the respective reduction gears 7, 8, and 9 can be smoothly rotated. Further, with this configuration, the reduction gears 7, 8, and 9 can be prevented from coming off the support shafts 29, 30, and 31.
又，於本實施形態中，係採用將支撐減速齒輪7、8、9之3個支軸29、30、31在位於等腰三角形之頂點之狀態下配置於光圈基板2之齒輪盒部17的構成。於該構成中，與將3個支軸29、30、31並排配置於一直線上之情形時相比，可將齒輪傳遞機構之佔據尺寸抑制為較小。尤其是，只要如上述圖4般將支軸30、31配置於較支軸29更靠光圈基板2之端部，便可有效地利用光圈基板2之角隅部之空間而配置減速齒輪7、9。又，藉由將自支軸29至支軸30之距離與自支軸29至支軸31之距離設定為相等，而使各個齒輪之直徑(齒頂圓直徑、基準圓直徑、齒根圓直徑等)共用化，可實現齒輪設計之容易化。又，亦可如上述實施形態般利用相同齒輪構成減速齒輪7與減速齒輪8。於在上述圖4中將支軸30、31配置於以軸線L1為中心而線對稱之位置之情形時亦可同樣地獲得此效果。 Further, in the present embodiment, the three support shafts 29, 30, and 31 supporting the reduction gears 7, 8, and 9 are disposed on the gear case portion 17 of the diaphragm substrate 2 in a state of being located at the apex of the isosceles triangle. Composition. In this configuration, the occupation size of the gear transmission mechanism can be suppressed to be smaller than when the three support shafts 29, 30, and 31 are arranged side by side on a straight line. In particular, if the support shafts 30 and 31 are disposed closer to the end portion of the diaphragm substrate 2 than the support shaft 29 as in the above-described FIG. 4, the reduction gear 7 can be disposed by effectively utilizing the space of the corner portion of the diaphragm substrate 2. 9. Further, by setting the distance from the support shaft 29 to the support shaft 30 to be equal to the distance from the support shaft 29 to the support shaft 31, the diameter of each gear (the tip circle diameter, the reference circle diameter, and the root diameter) Such as sharing, the gear design can be easily improved. Further, the reduction gear 7 and the reduction gear 8 may be configured by the same gear as in the above embodiment. This effect can be similarly obtained in the case where the support shafts 30 and 31 are disposed at positions symmetrical with respect to the axis L1 in the above-described FIG. 4 .
又，因採用將支撐減速齒輪7、8、9之支軸29、30、31 一體地設置於光圈基板2的構成，故而與例如上述專利文獻2所記載之光圈裝置般將支撐齒輪之支軸設置於與光圈基板不同之構件的情形時相比，可同時實現零件件數之削減與組裝步驟數之削減。 Also, by using the support shafts 29, 30, 31 which will support the reduction gears 7, 8, and 9. Since it is integrally provided in the diaphragm substrate 2, the number of parts can be simultaneously realized as compared with the case where the support shaft of the support gear is provided in a member different from the diaphragm substrate, for example, in the diaphragm device described in Patent Document 2 described above. Reduction and reduction in the number of assembly steps.

例如，於上述實施形態中，作為齒輪傳遞機構，係例示有於驅動齒輪65與作動齒輪52之間存在3個減速齒輪7、8、9之構成，但本發明並不限於此，亦可採用存在2個減速齒輪之構成、存在1個減速齒輪之構成、或者使驅動齒輪65直接嚙合於作動齒輪52之構成。 For example, in the above-described embodiment, the gear transmission mechanism is exemplified by the fact that three reduction gears 7, 8, and 9 are provided between the drive gear 65 and the actuation gear 52. However, the present invention is not limited thereto, and may be employed. There are two types of reduction gears, one configuration of one reduction gear, or a configuration in which the drive gear 65 is directly meshed with the actuation gear 52.
