原稿壓板開閉裝置及具有原稿壓板的辦公設備Original platen opening and closing device and office equipment with original platen

一種應用於影印機、印刷機、傳真機、掃描器等具有原稿壓板的辦公設備中的原稿壓板開閉裝置、及具有原稿壓板的辦公設備。An original platen opening and closing device applied to an office equipment having a document platen such as a photocopier, a printing machine, a facsimile machine, a scanner, and the like, and an office equipment having an original platen.

在影印機、印刷機、傳真機、掃描器等辦公設備的設備主體上，在該設備主體的上表面後部，透過原稿壓板開閉裝置可作開閉地安裝有原稿壓板。In the main body of the office equipment such as a photocopier, a printing machine, a facsimile machine, a scanner, and the like, a document pressing plate can be opened and closed by the original platen opening and closing device at the rear portion of the upper surface of the main body of the device.

原稿壓板開閉裝置是一種鉸鏈機構，其用於軸支承原稿壓板使其可繞鉸鏈軸轉動，從而能夠使原稿壓板壓緊在設備主體上表面的原稿台玻璃上，並且能夠使該原稿台玻璃露出(呈開放狀)。The original platen opening and closing device is a hinge mechanism for pivotally supporting the original platen so as to be rotatable about the hinge axis, thereby enabling the original platen to be pressed against the original platen glass on the upper surface of the apparatus main body, and the original platen glass can be exposed (Open).

為了將原稿設置在原稿台玻璃上，要使原稿壓板向上方翻開旋轉，以使原稿台玻璃露出(呈開放狀)，在將原稿放置到該原稿台玻璃上之後，使原稿壓板向相反方向旋轉而關閉，用原稿壓板使原稿壓緊在原稿台玻璃上，由此，能夠將原稿設置在原稿台玻璃上。In order to set the original on the original glass, the original pressure plate is turned upward to rotate the original glass (open), and the original pressure plate is placed in the opposite direction after the original is placed on the original glass. By rotating and closing, the original is pressed against the original glass by the original platen, whereby the original can be placed on the original glass.

在這樣的原稿壓板開閉裝置中，習知之原稿壓板開閉裝置：為了將書等之類厚度大的原稿穩定地壓緊在設備主體的上表面，而使原稿壓板開閉裝置能夠在設備主體的上下方向上移動(如參照專利文獻1和2)。專利文獻1和2所記載的原稿壓板開閉裝置具有在設備主體的高度方向上延伸之腳部，該腳部呈可滑動地插 入到設置在設備主體上的安裝孔中，從而原稿壓板開閉裝置可在設備主體的高度方向上移動地安裝在設備主體上。In the original platen opening and closing device, the original platen opening and closing device is configured such that a document having a large thickness such as a book is stably pressed against the upper surface of the apparatus main body, so that the original platen opening and closing device can be vertically moved in the apparatus main body. Move up (see, for example, Patent Documents 1 and 2). The original platen opening and closing device described in Patent Documents 1 and 2 has a leg portion extending in the height direction of the apparatus main body, and the leg portion is slidably inserted The document is placed in a mounting hole provided in the apparatus main body so that the original platen opening and closing device can be movably mounted on the apparatus main body in the height direction of the apparatus main body.

即，專利文獻1和2中所記載的原稿壓板開閉裝置，在遇到書等厚度較大的原稿的情況下，當在將原稿設置到原稿台玻璃上之後關閉原稿壓板時，原稿壓板開閉裝置會向設備主體的上方移動，原稿壓板能夠以與原稿台玻璃平行的狀態，與原稿面接觸地覆蓋在原稿台玻璃上，所以能夠將書等之類厚度大的原稿穩定地壓緊在設備主體的上表面上，而且能夠儘量防止外部光進入到設備主體的內部而妨礙曝光的情況。In the original document plate opening and closing device described in Patent Documents 1 and 2, when a document having a large thickness such as a book is encountered, the document plate opening and closing device is closed when the document platen is closed after the document is set on the platen glass. The original platen can be moved over the main body of the apparatus, and the original platen can be placed on the original glass in contact with the original surface in a state parallel to the original glass. Therefore, the original having a large thickness such as a book can be stably pressed against the main body of the apparatus. On the upper surface, it is possible to prevent external light from entering the inside of the apparatus body as much as possible to hinder the exposure.

另外，在專利文獻2中所記載的原稿壓板開閉裝置具有：安裝在辦公設備的設備主體上的安裝部件；通過第一鉸鏈銷可轉動地設置在該安裝部件上、並且安裝在原稿壓板上的支撐部件；和向打開方向對支撐部件施力的壓縮彈簧。憑藉該壓縮彈簧，通過支撐部件，原稿壓板被施力成向打開方向旋轉，因此在向打開方向旋轉原稿壓板時，借助壓縮彈簧的作用力，能夠感覺不到原本的重量地使原稿壓板旋轉。Further, the original platen opening and closing device described in Patent Document 2 has: a mounting member mounted on the apparatus main body of the office equipment; rotatably provided on the mounting member by the first hinge pin, and mounted on the original platen a support member; and a compression spring that urges the support member in an opening direction. By the compression spring, the original platen is biased to rotate in the opening direction by the support member. Therefore, when the original platen is rotated in the opening direction, the original platen can be prevented from rotating by the urging force of the compression spring.

專利文獻1：日本專利第3262457號Patent Document 1: Japanese Patent No. 3262457

專利文獻2：日本專利第3408111號Patent Document 2: Japanese Patent No. 3408111

但是在上述專利文獻1所述的原稿壓板開閉裝置的腳部上可旋轉地設有滾子部件，該滾子部件設置在腳部的後表面的下方處以及前表面的中央和上方之間處這兩個部位，因而在使原稿壓板 向關閉的方向旋轉的情況下，腳部在安裝孔內移動時，滾子部件與安裝孔的前表面和後表面的內壁接觸地滾動，因此可順暢地進行腳部的移動。該腳部以能夠在到設置在腳部的後表面下方的卡合部(緩衝吸收部件)與安裝孔的下端部卡合為止的區間內移動的方式***在安裝孔中，然而當腳部通過原稿壓板開閉裝置而向後部側傾倒時，則卡合部不與安裝孔的下端部卡合，腳部會從安裝孔中脫出。因此，在使原稿壓板開閉時還要考慮腳部從安裝孔中脫出的情況。However, the roller member is rotatably provided on the leg portion of the original platen opening and closing device described in Patent Document 1, and the roller member is disposed below the rear surface of the leg portion and between the center and the upper portion of the front surface. These two parts, thus making the original platen When the leg portion is rotated in the closing direction, when the leg portion moves in the mounting hole, the roller member rolls in contact with the inner wall of the front surface and the rear surface of the mounting hole, so that the movement of the leg portion can be smoothly performed. The leg portion is inserted into the mounting hole so as to be movable in a section until the engaging portion (buffer absorbing member) provided below the rear surface of the leg portion engages with the lower end portion of the mounting hole, but when the leg passes When the original platen opening and closing device is tilted toward the rear side, the engaging portion is not engaged with the lower end portion of the mounting hole, and the leg portion is released from the mounting hole. Therefore, it is also considered that the leg portion is detached from the mounting hole when the original platen is opened and closed.

另外，在專利文獻2所述的原稿壓板開閉裝置中，例如，壓縮彈簧容納在支撐部件內，壓縮彈簧的一個端部通過滑動件抵接在安裝部件上，且壓縮彈簧的另一端部抵接在支撐部件上。支撐部件還作為彈簧盒發揮作用，其通過具有高蠕變特性的合成樹脂形成為有底筒體形狀，但由於長年使用，有時會在壓縮彈簧所直接接觸的底部產生裂紋或底部產生破裂。因此提出了在支撐部件的外周以覆蓋底部和兩個側部的方式設置大致U字形狀的加強框體的方案。由此，雖然能夠防止支撐部件的破裂等，但是由於壓縮彈簧與支撐部件直接接觸，因而該壓縮彈簧帶來的應力僅特別作用在支撐部件的底部、壓縮彈簧的接觸部上，所以認為支撐部件會發生變形(凹陷)而破裂。Further, in the document platen opening and closing device described in Patent Document 2, for example, the compression spring is housed in the support member, one end portion of the compression spring abuts on the mounting member by the slider, and the other end portion of the compression spring abuts On the support member. The support member also functions as a spring case which is formed into a bottomed cylindrical shape by a synthetic resin having high creep property. However, due to long-term use, cracks may occur at the bottom portion directly contacted by the compression spring or cracks may occur at the bottom. Therefore, it has been proposed to provide a substantially U-shaped reinforcing frame on the outer circumference of the support member so as to cover the bottom portion and the two side portions. Thereby, although it is possible to prevent cracking or the like of the support member, since the compression spring is in direct contact with the support member, the stress caused by the compression spring acts only on the bottom portion of the support member and the contact portion of the compression spring, so that the support member is considered It will deform (depression) and rupture.

續接說明本發明之第一原稿壓板開閉裝置1與辦公設備10的作用。The operation of the first original platen opening and closing device 1 of the present invention and the office equipment 10 will be described.

如第1圖所示，於沒有使用設備主體11之狀態下，前述原稿壓板12緊貼於前述設備主體11之原稿台玻璃上，將前述原稿台玻璃覆蓋隱藏起來，要於前述原稿台玻璃上放置原稿，首先，抓住前述原稿壓板12之安裝有原稿壓板開閉裝置主體2之部位的相反側的端部或者其附近等，向上方抬起前述原稿壓板12，即，使原稿壓板12以鉸鏈銷24為軸旋轉，令前述原稿台玻璃面露出到外部，當依上述之方式旋轉前述原稿壓板12時，前述原稿壓板12藉由前述壓縮彈簧23a之作用力朝向打開之方向旋轉施力，所以能感覺不到重量地向打開方向旋轉。前述原稿壓板12能夠打開到前述凸輪凸部25e與前述凸輪卡合部21e抵接(參見圖4)。As shown in Fig. 1, the original platen 12 is in close contact with the original platen of the apparatus main body 11 in a state where the apparatus main body 11 is not used, and the original document glass cover is hidden, and is applied to the original original glass. When the original is placed, first, the end portion of the original platen 12 on the opposite side to the portion where the original platen opening and closing device main body 2 is attached, or the vicinity thereof is grasped, and the original platen 12 is lifted upward, that is, the original platen 12 is hinged. When the pin 24 is rotated by the shaft, the glass surface of the original platen is exposed to the outside. When the original platen 12 is rotated as described above, the original platen 12 is rotatably biased in the direction of opening by the urging force of the compression spring 23a. It can rotate in the opening direction without feeling the weight. The document holding plate 12 can be opened until the cam convex portion 25e abuts against the cam engaging portion 21e (see FIG. 4).

在將原稿放置在所露出之原稿台玻璃面上之後，令抬起的原稿壓板12下降，即，令原稿壓板12向與前述原稿台玻璃接觸的關閉方向以鉸鏈銷24為軸作旋轉，令其向下方移動而成為關閉狀 態。此時，如果原稿是較薄的物品例如1張薄紙，則原稿壓板12僅以鉸鏈銷24為軸作旋轉，利用前述原稿壓板12令原稿緊貼在原稿台玻璃上，而不會從原稿台玻璃上浮起，並盡可能地防止了外部光進入到設備主體11的內部而妨礙曝光，所以能夠良好地對原稿進行複印等。After the original is placed on the exposed glass surface of the original platen, the raised original platen 12 is lowered, that is, the original platen 12 is rotated about the hinge pin 24 in the closing direction of the contact with the original platen glass, It moves downwards to become closed state. At this time, if the original is a thin article such as one thin paper, the original pressing plate 12 is rotated only by the hinge pin 24, and the original pressing plate 12 is used to make the original adhere to the original glass without the original platen. The glass floats up and prevents external light from entering the inside of the apparatus main body 11 as much as possible, thereby preventing exposure, so that the original can be easily copied or the like.

另外，當前述原稿如書那樣厚度大的情況下，當令打開之原稿壓板12向關閉方向作旋轉時，於前述原稿壓板12成為關閉狀態之前，即在原稿壓板12大致呈平行於前述設備主體的上表面(原稿台玻璃)之前，前述原稿壓板12與前述原稿之端部接觸，於前述原稿與前述端部相反之一側的端部與前述原稿壓板12之間形成了空間。即，前述原稿壓板12成為與前述原稿壓板開閉裝置主體2相反一側的端部浮起的狀態。透過將前述浮起側之原稿壓板12按壓向前述設備主體11側，或透過前述原稿壓板12本身之重量，前述腳部3向前述安裝孔15脫出之方向(上方)移動，前述原稿壓板開閉裝置主體2向上方移動，並前述原稿壓板12以鉸鏈銷24為軸作旋轉，即以覆蓋原稿的上部的方式，自動調節前述原稿壓板開閉裝置主體2的高度令前述原稿壓板12移動(例如參見圖5)。例如，在前述原稿的上部為平坦面的情況下，前述原稿壓板12與其上部面接觸，其結果為，厚度較大之原稿穩定地緊貼於前述原稿台玻璃上。因此，前述原稿壓板12可與原稿的厚度無關地使原稿穩定地緊貼在原稿台玻璃上。Further, when the original document has a large thickness as in the book, when the opened original platen 12 is rotated in the closing direction, before the original pressing plate 12 is in the closed state, that is, the original pressing plate 12 is substantially parallel to the apparatus main body. Before the upper surface (original table glass), the original platen 12 is in contact with the end portion of the document, and a space is formed between the end portion of the document opposite to the end portion and the original platen 12. In other words, the document platen 12 is in a state in which the end portion on the side opposite to the document platen opening and closing device main body 2 is floated. The original platen 12 of the floating side is pressed toward the apparatus main body 11 or the weight of the original platen 12 itself is moved, and the leg portion 3 is moved in the direction in which the attachment hole 15 is released (upward), and the original platen is opened and closed. The apparatus main body 2 is moved upward, and the original platen 12 is rotated about the hinge pin 24, that is, the height of the original platen opening and closing device main body 2 is automatically adjusted so as to cover the upper portion of the original document, so that the original platen 12 is moved (for example, see Figure 5). For example, when the upper portion of the document is a flat surface, the document platen 12 is in contact with the upper surface thereof, and as a result, the document having a large thickness is stably adhered to the document glass. Therefore, the document platen 12 can stably adhere the document to the platen glass regardless of the thickness of the document.

因次，當前述腳部3於前述安裝孔15內之高度方向上作移動時，於前述安裝孔15之兩個側壁15a上各設置有2個的輥子部件6分別由前述腳部3之引導槽5引導，故前述腳部3可靠且順暢地進行移動。另外，即令欲從前述安裝孔15中拔出原稿壓板12之腳部3，下方之輥子部件6也與前述引導槽5之終端部51卡合，腳部3不會由前述安裝孔15中脫出。Then, when the leg portion 3 moves in the height direction of the mounting hole 15, two roller members 6 are provided on each of the two side walls 15a of the mounting hole 15 and guided by the leg portion 3, respectively. Since the groove 5 is guided, the leg portion 3 is reliably and smoothly moved. Further, even if the leg portion 3 of the original platen 12 is to be pulled out from the mounting hole 15, the lower roller member 6 is also engaged with the end portion 51 of the guide groove 5, and the leg portion 3 is not detached from the mounting hole 15 Out.

因此，本發明之第一原稿壓板開閉裝置1與辦公設備10不但前述腳部3能順暢地進行移動，而且前述腳部3不會從前述安裝孔15中脫出。Therefore, in the first document platen opening and closing device 1 and the office equipment 10 of the present invention, not only the leg portion 3 can be smoothly moved, but also the leg portion 3 does not come out of the mounting hole 15.

另外，當前述原稿壓板12作開閉時，前述壓縮彈簧23a進行伸縮，並且前述凸輪滑動件25於前述支撐部件22內滑動，即，於前述原稿壓板12關閉之狀態下，如第3圖所示，前述壓縮彈簧23a為收縮之狀態，從該狀態令前述原稿壓板12以鉸鏈銷24為軸向打開之方向作旋轉。Further, when the original platen 12 is opened and closed, the compression spring 23a expands and contracts, and the cam slider 25 slides in the support member 22, that is, in a state where the original platen 12 is closed, as shown in FIG. The compression spring 23a is in a contracted state, and from this state, the original platen 12 is rotated in a direction in which the hinge pin 24 is opened in the axial direction.

於是，前述凸輪滑動件25之凸輪凸部25e於受壓部21d上呈可滑動地接觸向凸輪卡合部21e之方向移動，前述原稿壓板12呈打開之狀態，此時，前述凸輪凸部25e所接觸之受壓部21d與前述支撐部件22的封閉部22d之間的間隔變寬，前述凸輪滑動件25借助於前述壓縮彈簧23a的作用力在前述支撐部件22內作滑動，然後，當前述凸輪凸部25e與前述凸輪卡合部21e抵接時，前述原稿壓板12呈最大的打開狀態。Then, the cam convex portion 25e of the cam slider 25 is slidably contacted in the direction of the cam engagement portion 21e on the pressure receiving portion 21d, and the original pressing plate 12 is opened. At this time, the cam convex portion 25e The interval between the contacted pressure receiving portion 21d and the closing portion 22d of the support member 22 is widened, and the cam slider 25 is slid in the support member 22 by the urging force of the compression spring 23a, and then, as described above When the cam convex portion 25e comes into contact with the cam engagement portion 21e, the original platen 12 is in the maximum open state.

如圖4所示，該狀態為壓縮彈簧23a伸長的狀態。As shown in Fig. 4, this state is a state in which the compression spring 23a is extended.

透過由前述狀態令原稿壓板12以鉸鏈銷24為軸向關閉之方向作旋轉，且能夠關閉原稿壓板12，此時，前述凸輪凸部25e所接觸之受壓部21d與前述支撐部件22之封閉部22d之間的間隔變窄，凸輪滑動件25抵抗壓縮彈簧23a的作用力在支撐部件22內滑動，同時，壓縮彈簧23a收縮。The original platen 12 is rotated in the direction in which the hinge pin 24 is axially closed by the aforementioned state, and the original platen 12 can be closed. At this time, the pressed portion 21d to which the cam convex portion 25e is in contact with the support member 22 is closed. The interval between the portions 22d is narrowed, and the cam slider 25 slides in the support member 22 against the urging force of the compression spring 23a, while the compression spring 23a contracts.

因此，原稿壓板12關閉的狀態通常為沒有使用設備主體11之狀態，壓縮彈簧23a為收縮的狀態，該壓縮彈簧23a的應力雖然特別作用在支撐部件22的封閉部22d側，但由於在壓縮彈簧23a之另一個端部與支撐部件22的封閉部22d之間設有加強殼體26的加強部26a，故前述壓縮彈簧23a之應力作用在加強殼體26上，幾乎不會作用在支撐部件22的封閉部22d上，因此本發明之第一原稿壓板開閉裝置1能夠進一步防止彈簧盒28的破裂等。Therefore, the state in which the original platen 12 is closed is generally in a state where the apparatus main body 11 is not used, and the compression spring 23a is in a contracted state, and the stress of the compression spring 23a acts particularly on the side of the closing portion 22d of the support member 22, but due to the compression spring A reinforcing portion 26a of the reinforcing casing 26 is provided between the other end portion of the bearing member 23a and the closing portion 22d of the supporting member 22, so that the stress of the compression spring 23a acts on the reinforcing casing 26 and hardly acts on the supporting member 22. Therefore, the first original platen opening and closing device 1 of the present invention can further prevent the spring box 28 from being broken or the like.

另外，容設有壓縮彈簧23a的一個端部的凸輪滑動件25透過原稿壓板12的開閉操作，而在設置於支撐部件22內的加強殼體26內滑動，故支撐部件22(彈簧盒28)不致會破裂，即，在凸輪滑動件25之上表面設有加強殼體26的上方的滑動片26e，並且在凸輪滑動件25的兩個側面設有加強殼體26之兩個側部26b，且在凸輪滑動件25之下表面設有下方的滑動片26f，因而當凸輪滑動件25於支撐部件22內滑動時，凸輪滑動件25不與支撐部件22接觸地進行滑動，所以能進一步防止支撐部件22(彈簧盒28)的 破裂等。Further, the cam slider 25, which is provided with one end portion of the compression spring 23a, is slidable in the reinforcing case 26 provided in the support member 22 through the opening and closing operation of the original platen 12, so that the support member 22 (spring case 28) There is no rupture, that is, a sliding piece 26e above the reinforcing casing 26 is provided on the upper surface of the cam slider 25, and two side portions 26b of the reinforcing casing 26 are provided on both sides of the cam slider 25, Further, a lower sliding piece 26f is provided on the lower surface of the cam slider 25, so that when the cam slider 25 slides in the support member 22, the cam slider 25 does not slide in contact with the support member 22, so that the support can be further prevented. Component 22 (spring box 28) Broken and so on.

並於前述第一原稿壓板開閉裝置中，將引導槽5分別設置在腳部3的兩個側面3a上，且將輥子部件6分別設於安裝孔15之兩個側壁15a上，但並不限於此，亦可如第15圖所示，貫穿腳部3之兩個側面3a地設置引導槽55，並令前述輥子部件65貫穿引導槽55且將該兩端部安裝在安裝孔150之兩個側壁150a上。In the first original platen opening and closing device, the guide grooves 5 are respectively disposed on the two side faces 3a of the leg portion 3, and the roller members 6 are respectively disposed on the two side walls 15a of the mounting hole 15, but are not limited thereto.

The roller portion 67 is formed to be shorter than a dimension between the two wall portions of the guide groove 55, for example, a slightly shorter diameter. When the leg portion 3 is moved along the mounting hole 150, the roller portion 67 is in the aforementioned guide groove. When the inside of the shaft 55 is rotated, the leg portion 3 can be smoothly moved. On the outer circumference near the both end portions of the shaft 66, as shown in Fig. 15, mounting grooves 66a for mounting the E-ring 68 are provided, respectively.

安裝孔150如透過コ字形狀的安裝孔形成部件160所構形，安裝孔形成部件160如將板料彎折成コ字形狀所構形，安裝孔形成部件160之兩端部朝外側彎折而形成為凸緣部160a，於前述安 裝孔形成部件160上設有用於安裝輥子部件65之通孔160b。The mounting hole 150 is configured by a U-shaped mounting hole forming member 160. The mounting hole forming member 160 is formed by bending a sheet into a U shape, and both ends of the mounting hole forming member 160 are bent outward. Folded to form a flange portion 160a, in the aforementioned The hole forming member 160 is provided with a through hole 160b for mounting the roller member 65.

於前述輥子部件65之組裝中，首先令前述輥子部67位於腳部3之引導槽55內，於此狀態下，將前述腳部3插設於形成安裝孔150之安裝孔形成部件160內，令前述輥子部67與通孔160b軸對齊，向前述通孔160b與輥子部67中***軸66並令軸66作貫穿，分別將E環68安裝在軸66之安裝孔形成部件160的兩個側部突出之兩端部的安裝槽66a中，由此，於輥子部件65與引導槽55卡合的狀態下組裝好前述輥子部件65，可獲得與前述相同之作用效果，既能夠順暢地進行腳部3的移動，且前述腳部3不會從安裝孔150脫出。In the assembly of the roller member 65, first, the roller portion 67 is placed in the guide groove 55 of the leg portion 3. In this state, the leg portion 3 is inserted into the mounting hole forming member 160 in which the mounting hole 150 is formed. The roller portion 67 is axially aligned with the through hole 160b, the shaft 66 is inserted into the through hole 160b and the roller portion 67, and the shaft 66 is inserted therethrough, and the E ring 68 is attached to the mounting hole forming member 160 of the shaft 66, respectively.

另者，於前述第一安裝孔形成部件71與第二安裝孔形成部件72中之任一安裝孔形成部件，如前述第一安裝孔形成部件71上，設有如6個於前述第一安裝孔形成部件71之寬度方向上延伸，且於內表面上具有螺紋槽之安裝孔71c，於前述第一安裝孔形成部件71與第二安裝孔形成部件72中的另一個安裝孔形成部件，如前述第二安裝孔形成部件72上，於與前述安裝孔71c相對應之6個部 位分別設有，於前述第二安裝孔形成部件72之寬度方向上延伸且貫穿的安裝孔72c，將前述第一安裝孔形成部件71與第二安裝孔形成部件72相互組合，並透過前述小螺釘與螺絲等元件相互固定在一起。In addition, any one of the first mounting hole forming member 71 and the second mounting hole forming member 72, such as the first mounting hole forming member 71, is provided with six first mounting holes. a mounting hole 71c extending in the width direction of the forming member 71 and having a thread groove on the inner surface, and another mounting hole forming member in the first mounting hole forming member 71 and the second mounting hole forming member 72, as described above The second mounting hole forming member 72 is provided in the six portions corresponding to the mounting hole 71c. The mounting holes 72c extending in the width direction of the second mounting hole forming member 72 are respectively provided, and the first mounting hole forming member 71 and the second mounting hole forming member 72 are combined with each other and transmitted through the aforementioned small Components such as screws and screws are fixed to each other.

另者，於前述第一安裝孔形成部件71與第二安裝孔形成部件72彼此對應設置的面上，分別設有於它們之高度方向上延伸且用於構形成安裝孔15之凹狀的安裝孔形成凹部73、74。In addition, on the surfaces of the first mounting hole forming member 71 and the second mounting hole forming member 72 that are disposed corresponding to each other, recessed mountings extending in the height direction thereof and configured to form the mounting holes 15 are respectively provided. The holes form recesses 73, 74.

如第16、17圖所示，輥子部件8設置於前述腳部3之兩個側面3a上並能夠於寬度方向上延伸之軸為中心旋轉，作為輥子部件8，雖然並不特別限定，如從前述腳部3之兩個側面3a向其寬度方向突出延伸之軸81、82，可作支撐使用且繞前述軸81、82作旋轉的輥子部83；前述軸81、82透過螺紋機構等相互螺合而構形成一根軸，前述軸81、82之長度尺寸以較前述貫穿腳部3之兩個側面3a之通孔31為要長之尺寸，並前述軸81、82係插設於前述通孔31中，於軸81、82之通孔31(兩個側面3a)突出之兩端部的外周上，分別可繞前述軸呈可轉動地設有輥子部83。As shown in Figs. 16 and 17, the roller member 8 is provided on the both side faces 3a of the leg portion 3 and is rotatable about an axis extending in the width direction. The roller member 8 is not particularly limited as it is. The shafts 81 and 82 projecting from the two side faces 3a of the leg portion 3 in the width direction thereof can be used as a roller portion 83 for supporting and rotating around the shafts 81 and 82; the shafts 81 and 82 are mutually screwed by a screw mechanism or the like. One shaft is formed, and the lengths of the shafts 81 and 82 are longer than the through holes 31 of the two side faces 3a of the through leg 3, and the shafts 81 and 82 are inserted into the aforementioned shafts. In the hole 31, roller portions 83 are rotatably provided around the shaft on the outer circumferences of both end portions of the through holes 31 (two side faces 3a) of the shafts 81 and 82.

於軸81、82之兩端部上，設有帶墊圈的螺紋部件84，令前述輥子部83不會由前述軸81、82之兩端部脫出。Screw members 84 with washers are provided on both ends of the shafts 81 and 82 so that the roller portions 83 are not released from the both ends of the shafts 81 and 82.

輥子部83以較引導槽7的兩個壁部7a之間的尺寸要小、如形成略小於前述輥子部83之直徑的尺寸，當令腳部3沿著安裝孔15移動時，輥子部83可於引導槽7內作旋轉，同時前述腳部3 能夠順暢地移動。The roller portion 83 is smaller in size than the two wall portions 7a of the guide groove 7, and is formed to have a size slightly smaller than the diameter of the aforementioned roller portion 83. When the leg portion 3 is moved along the mounting hole 15, the roller portion 83 can be Rotating in the guiding groove 7 while the aforementioned foot 3 It can move smoothly.

即，前述輥子部件8與引導槽7的兩個壁部7a呈滑動接觸、並同時由前述引導槽7所引導，較佳於前述腳部3的兩個側面3a上分別設置有複數個輥子部件8。That is, the roller member 8 is in sliding contact with the two wall portions 7a of the guide groove 7, and is simultaneously guided by the guide groove 7, and preferably, a plurality of roller members are respectively disposed on the two side faces 3a of the leg portion 3 8.

具體而言，前述輥子部件8較佳設置於腳部3的兩個側面3a的大致中央部與下方部這兩個部位；由此，前述腳部3(原稿壓板開閉裝置主體2)能夠於前述安裝部件21之底部21a與設備主體11的上表面接觸的狀態到上方的輥子部件8與引導槽7的上端部接觸的區間內，於上下方向上作移動。Specifically, the roller member 8 is preferably provided at two central portions and a lower portion of the both side faces 3a of the leg portion 3; whereby the leg portion 3 (original platen opening and closing device main body 2) can be formed as described above. The state in which the bottom portion 21a of the mounting member 21 is in contact with the upper surface of the apparatus main body 11 moves in the vertical direction in a section where the upper roller member 8 is in contact with the upper end portion of the guide groove 7.

如此亦可獲得與上述相同之作用效果，即，當前述腳部3於前述安裝孔15內之高度方向上作移動，由於在腳部3之兩個側面3a上分別設置有2個輥子部件8，並分別由前述安裝孔15之引導槽7所引導，故腳部3能順暢地進行移動。In this way, the same effect as described above can be obtained, that is, when the leg portion 3 is moved in the height direction of the mounting hole 15, since two roller members 8 are respectively provided on the two side faces 3a of the leg portion 3 And guided by the guide grooves 7 of the mounting holes 15, respectively, the leg portions 3 can be smoothly moved.

此外，即令欲從安裝孔15中拔出原稿壓板12的腳部3，上方的輥子部件8也會與前述引導槽7之終端部151卡合，腳部3不會從安裝孔15脫出。因此，本發明之第二原稿壓板開閉裝置90不但能順暢地進行腳部3的移動，而且腳部3不會從安裝孔15脫出。Further, even if the leg portion 3 of the original platen 12 is to be pulled out from the mounting hole 15, the upper roller member 8 is also engaged with the end portion 151 of the guide groove 7, and the leg portion 3 does not come out of the mounting hole 15. Therefore, the second original platen opening and closing device 90 of the present invention can smoothly move the leg portion 3 and the leg portion 3 does not come out of the attachment hole 15.

第20圖與第21圖是表示本發明之第三原稿壓板開閉裝置之一種實施例之圖示，如第20、21圖所示，本發明之第三原稿壓板開閉裝置主要的特徵在於，腳部103還作為彈簧盒28，在前述彈 簧盒28內設有加強框體9。20 and 21 are views showing an embodiment of a third original platen opening and closing device of the present invention. As shown in Figs. 20 and 21, the third original platen opening and closing device of the present invention is mainly characterized by a foot. The part 103 also acts as a spring box 28 in the aforementioned bullet A reinforcing frame 9 is provided in the spring box 28.

另外，下文中說明第三原稿壓板開閉裝置100，但對於與上述第一原稿壓板開閉裝置1相同的部分標以相同名稱並有時省略其說明。In addition, although the third original platen opening and closing device 100 will be described below, the same portions as those of the first original platen opening and closing device 1 will be designated by the same names, and description thereof may be omitted.

腳部103從安裝部件121向下方突出地設置，前述腳部103係由合成樹脂等形成為下端部(底部)被封閉的大致呈矩形的筒體狀，即為一有底筒體狀；於前述腳部103內容設有作為彈性部件23的壓縮彈簧23a，腳部103係兼作為彈簧盒28。The leg portion 103 is provided to protrude downward from the mounting member 121, and the leg portion 103 is formed of a synthetic resin or the like in a substantially rectangular tubular shape in which the lower end portion (bottom portion) is closed, that is, a bottomed cylindrical body shape; The leg portion 103 is provided with a compression spring 23a as an elastic member 23, and the leg portion 103 also serves as a spring case 28.

於前述腳部103內可呈滑動地以***方式容設有凸輪滑動件125，於前述安裝部件121上連接有能以鉸鏈銷124為軸進行轉動的支撐部件122，於前述支撐部件122上設有凸輪部122a，於該凸輪部122a上呈壓力接觸設有凸輪滑動件125，並如第20、21圖中，標號127實際上表示與凸輪部122a壓力接觸之杆銷。A cam slider 125 is slidably inserted into the leg portion 103, and a support member 122 that can rotate about the hinge pin 124 is connected to the mounting member 121, and the support member 122 is disposed on the support member 122. There is a cam portion 122a on which the cam slider 125 is provided in pressure contact, and as in Figs. 20 and 21, reference numeral 127 actually indicates a lever pin which is in pressure contact with the cam portion 122a.

於腳部103(彈簧盒28)內設有加強框體9，前述加強框體9係為具有加強部126a的加強殼體126，前述加強部126a位於腳部103之底部103a的內表面與壓縮彈簧23a的端部之間，前述加強殼體126係為由合成樹脂構成的支撐部件122的蠕變(加強)措施，其係將鋼板等材料作折彎而形成。A reinforcing frame 9 is provided in the leg portion 103 (spring case 28). The reinforcing frame body 9 is a reinforcing case 126 having a reinforcing portion 126a. The reinforcing portion 126a is located on the inner surface of the bottom portion 103a of the leg portion 103 and is compressed. Between the ends of the springs 23a, the reinforcing casing 126 is a creeping (strengthening) measure of the support member 122 made of synthetic resin, which is formed by bending a material such as a steel plate.

加強殼體126係由與腳部103之底部103a的內表面以面接觸的加強部126a與側部126b形成為大致コ字形狀，前述側部126b透過將該加強部126a之兩側端部彎折成大致呈直角，並與前述腳 部103之側部呈面接觸。The reinforcing case 126 is formed in a substantially U shape by a reinforcing portion 126a and a side portion 126b that are in surface contact with the inner surface of the bottom portion 103a of the leg portion 103, and the side portion 126b is bent to bend both end portions of the reinforcing portion 126a. Fold into a substantially right angle and with the aforementioned foot The side of the portion 103 is in surface contact.

前述側部126b之長度較佳係以較鉸鏈銷124所在之位置要長之尺寸，於前述加強殼體126之兩個側部126b上設有貫穿***鉸鏈銷124的銷孔(圖中未表示)，另外於前述加強殼體26之兩側端部上分別設有滑動片126e、126f，凸輪滑動件125於前述滑動片126e、126f以及側部126b內呈可滑動。Preferably, the length of the side portion 126b is longer than the position at which the hinge pin 124 is located. The two side portions 126b of the reinforcing housing 126 are provided with pin holes through which the hinge pin 124 is inserted (not shown). Further, on both side ends of the reinforcing casing 26, sliding pieces 126e and 126f are respectively provided, and the cam sliding members 125 are slidable in the sliding pieces 126e and 126f and the side portions 126b.

續接下述說明係為本發明之第三原稿壓板開閉裝置100與辦公設備10之作用說明，於沒有使用設備主體11之狀態下，前述原稿壓板12緊貼於前述設備主體11之原稿台玻璃上，將前述原稿台玻璃覆蓋隱藏起來，當要在前述原稿台玻璃上放置原稿，要使原稿壓板12以鉸鏈銷124為軸作旋轉，令前述原稿台玻璃面呈露出之狀態，當如前述之方式旋轉原稿壓板12時，原稿壓板12係以壓縮彈簧23a的作用力而向被打開之方向旋轉施力，故無感覺重量地使原稿壓板12向打開方向作旋轉。The following description is the operation of the third original platen opening and closing device 100 and the office equipment 10 of the present invention. The original platen 12 is in close contact with the original platen of the apparatus main body 11 in a state where the apparatus main body 11 is not used. In the above, the cover glass cover is hidden, and when the original is to be placed on the original glass, the original pressure plate 12 is rotated about the hinge pin 124, so that the glass surface of the original plate is exposed, as described above. When the original platen 12 is rotated, the original platen 12 is rotatably biased in the direction in which it is opened by the urging force of the compression spring 23a, so that the original platen 12 is rotated in the opening direction without feeling the weight.

當將原稿放置於所露出之原稿台玻璃之面上後，令抬起之原稿壓板12下降，此時，如果原稿係為較薄之物品如為一張薄紙，則原稿壓板12僅以鉸鏈銷124為軸作旋轉，利用前述原稿壓板12令前述原稿緊貼於原稿台玻璃上，而不會從原稿台玻璃上呈浮起狀，並且盡可能地防止了外部光進入至設備主體11之內部而妨礙曝光，故能夠良好地對原稿進行複印等。When the original is placed on the surface of the exposed original glass, the raised original platen 12 is lowered. At this time, if the original is a thin article such as a thin paper, the original pressing plate 12 is only a hinge pin. 124 is rotated by the shaft, and the original document is pressed against the original platen glass by the above-described original platen 12 without floating from the original platen glass, and external light is prevented from entering the inside of the apparatus main body 11 as much as possible. Since the exposure is hindered, it is possible to copy the original or the like well.

當前述原稿如書那樣厚度大之情況下，當令打開的原稿壓板 12向關閉方向作旋轉時，於前述原稿壓板12呈關閉狀態之前，即，於前述原稿壓板12大致平行於設備主體之上表面(原稿台玻璃)之前，原稿壓板12與原稿的端部接觸，於前述原稿與前述端部相反一側的端部與原稿壓板12之間形成有一空間。When the aforementioned original is as thick as a book, when the original plate is opened 12 is rotated in the closing direction, before the original pressing plate 12 is in a closed state, that is, before the original pressing plate 12 is substantially parallel to the upper surface of the apparatus main body (original table glass), the original pressing plate 12 is in contact with the end portion of the original. A space is formed between the end portion of the original document on the side opposite to the end portion and the original platen 12.

即，前述原稿壓板12成為與原稿壓板開閉裝置主體2相反一側的端部呈浮起之狀態，透過將該浮起側的原稿壓板12按壓向設備主體11側，或透過前述原稿壓板12的本身之重量，腳部103從安裝孔115脫出之方向(上方)移動，前述原稿壓板開閉裝置主體2向上方移動，並原稿壓板12以鉸鏈銷124為軸作旋轉。In other words, the original platen 12 is in a state in which the end portion opposite to the original platen opening and closing device main body 2 is floated, and the original platen 12 on the floating side is pressed toward the apparatus main body 11 side or through the original platen 12. The weight 103 itself moves in the direction in which the leg portion 103 is disengaged (upward), the original platen opening and closing device main body 2 moves upward, and the original platen 12 rotates about the hinge pin 124.

即，以覆蓋原稿之上部的方式，自動調節原稿壓板開閉裝置主體2的高度使原稿壓板12移動，如於前述原稿之上部為平坦面的情況下，前述原稿壓板12與上部面作接觸，其結果為前述厚度大之原稿穩定地緊貼於原稿台玻璃上。That is, the height of the original platen opening and closing device main body 2 is automatically adjusted so as to cover the upper portion of the original document, and the original platen 12 is moved. When the upper portion of the original document is a flat surface, the original pressing plate 12 is in contact with the upper surface. As a result, the original having a large thickness described above is stably adhered to the original glass.

因此，前述原稿壓板12可與原稿之厚度無關地令原稿穩定地緊貼於原稿台玻璃上。Therefore, the original platen 12 can stably adhere the original to the original glass regardless of the thickness of the original.

當原稿壓板12開閉時，壓縮彈簧23a進行伸縮，並且凸輪滑動件125在腳部103內滑動，即，在原稿壓板12關閉的狀態下，壓縮彈簧23a呈收縮之狀態，從前述狀態令原稿壓板12以鉸鏈銷124為軸向打開之方向作旋轉，於是，前述凸輪滑動件125之杆銷127於支撐部件122的凸輪部122a上以滑動接觸作移動，前述原稿壓板12呈打開之狀態，此時，杆銷127與前述腳部103之底部 103a之間的間隔變寬，凸輪滑動件125借助於壓縮彈簧23a的作用力於腳部103內滑動。When the original platen 12 is opened and closed, the compression spring 23a expands and contracts, and the cam slider 125 slides in the leg portion 103, that is, in a state where the original platen 12 is closed, the compression spring 23a is in a contracted state, and the original platen is made from the aforementioned state. 12 is rotated in a direction in which the hinge pin 124 is axially opened, so that the lever pin 127 of the cam slider 125 is moved in sliding contact on the cam portion 122a of the support member 122, and the original platen 12 is opened. At the time, the lever pin 127 and the bottom of the aforementioned leg portion 103 The interval between the 103a is widened, and the cam slider 125 slides in the leg portion 103 by the action of the compression spring 23a.

透過從前述原稿壓板12打開之狀態令前述原稿壓板12以鉸鏈銷124為軸向關閉之方向作旋轉，並能夠關閉前述原稿壓板12，此時，前述杆銷127與腳部103之底部103a之間的間隔變窄，前述凸輪滑動件125抵抗壓縮彈簧23a的作用力於腳部103內滑動，同時，令壓縮彈簧23a呈收縮狀態。The original platen 12 is rotated in a direction in which the hinge pin 124 is axially closed by the state in which the original platen 12 is opened, and the original platen 12 can be closed. At this time, the rod pin 127 and the bottom portion 103a of the leg portion 103 are closed. The interval between the two is narrowed, and the cam slider 125 slides against the force of the compression spring 23a in the leg portion 103, and at the same time, the compression spring 23a is in a contracted state.

故，前述原稿壓板12關閉之狀態通常為設備主體11沒有使用之狀態，前述壓縮彈簧23a呈收縮之狀態，前述壓縮彈簧23a之應力特別作用於前述腳部103之底部103a側，但由於在壓縮彈簧23a的另一個端部與腳部103的底部103a之間設有加強殼體126的加強部126a，故前述壓縮彈簧23a之應力作用在前述加強殼體126上，幾乎不會作用於前述腳部103的底部103a上。Therefore, the state in which the original platen 12 is closed is generally in a state in which the apparatus main body 11 is not in use, and the compression spring 23a is in a contracted state, and the stress of the compression spring 23a acts particularly on the bottom 103a side of the leg portion 103, but is compressed. A reinforcing portion 126a of the reinforcing casing 126 is provided between the other end of the spring 23a and the bottom portion 103a of the leg portion 103, so that the stress of the compression spring 23a acts on the reinforcing casing 126, and hardly acts on the aforementioned foot. On the bottom 103a of the portion 103.

因此，本發明涉之第二原稿壓板開閉裝置100進者防止彈簧盒28的破裂等。Therefore, the second original platen opening and closing device 100 according to the present invention prevents the spring case 28 from being broken or the like.

另外，容設有壓縮彈簧23a的一個端部之凸輪滑動件125透過原稿壓板12之開閉操作，而在設置於前述腳部103內之加強殼體126內作滑動，所以前述腳部103(彈簧盒28)不會破裂。In addition, the cam slider 125, which is provided with one end of the compression spring 23a, passes through the opening and closing operation of the original platen 12, and slides in the reinforcing case 126 provided in the leg portion 103, so that the leg portion 103 (spring) Box 28) will not break.

即，當前述凸輪滑動件125於腳部103內作滑動時，前述凸輪滑動件125並不與前述腳部103呈接觸地進行滑動，所以能進一步可靠地防止腳部103(彈簧盒28)的破裂等。That is, when the cam slider 125 slides in the leg portion 103, the cam slider 125 does not slide in contact with the leg portion 103, so that the leg portion 103 (spring case 28) can be further reliably prevented. Broken and so on.

如上所述，本發明之原稿壓板開閉裝置由於在前述腳部之側面或者於上述安裝孔的側壁上設置引導槽，於前述安裝孔之側壁或者腳部的側面上設置由引導槽所引導的輥子部件，引導槽具有透過與輥子部件卡合來防止腳部的脫出的終端部，因此不但能夠順暢地進行腳部的移動，而且腳部不會從安裝孔脫出。As described above, the original platen opening and closing device of the present invention is provided with a guide groove on the side surface of the leg portion or on the side wall of the mounting hole, and a roller guided by the guide groove is provided on the side wall of the mounting hole or the side surface of the leg portion. In the member, the guide groove has a terminal portion that is inserted into the roller member to prevent the leg portion from coming out. Therefore, the leg portion can be smoothly moved and the leg portion can be prevented from coming out of the mounting hole.

另者，透過於彈簧盒內設置截面為大致U字形狀的加強框體包圍上述壓縮彈簧，並使該加強框體的至少開放端側的兩個端部連接在鉸鏈銷上，前述壓縮彈簧之應力作用於加強框體上，而幾乎不會作用在支撐部件的底部上，進者可防止彈簧盒的破裂等，因而本發明特別適於用作影印機、印刷機、傳真機、掃描器等辦公設備的原稿壓板開閉裝置。Further, the compression spring is surrounded by a reinforcing frame having a substantially U-shaped cross section in the spring case, and at least two end portions of the reinforcing frame body on the open end side are connected to the hinge pin, and the compression spring is The stress acts on the reinforcing frame, and hardly acts on the bottom of the supporting member, so that the spring box can be prevented from being broken, and the like, and thus the present invention is particularly suitable for use as a photocopier, a printing machine, a facsimile machine, a scanner, etc. Original platen opening and closing device for office equipment.
