  Next, the operation of the first document crimping plate opening / closing device 1 and the office equipment 10 according to the present invention will be described.

  When the apparatus main body 11 is not used, the original cover 12 is in close contact with the contact glass of the apparatus main body 11 to cover the contact glass as shown in FIG. In order to place a document on the contact glass, first, the document crimping plate is held by holding the end of the document crimping plate 12 on the side opposite to the portion where the document crimping plate opening / closing device body 2 is attached, or the vicinity thereof. Lift 12 up. That is, the original cover 12 is rotated about the hinge pin 24 to expose the contact glass surface to the outside. Thus, when the original cover 12 is rotated, the original cover 12 is urged to rotate in the opening direction by the urging force of the compression spring 23a, so that it can rotate in the opening direction without feeling weight. . The original cover 12 can be opened until the cam projection 25e comes into contact with the cam engagement portion 21e (see FIG. 4).

  After placing the document on the exposed contact glass surface, the lifted document pressing plate 12 is lowered. In other words, the original cover 12 is rotated in the closing direction in contact with the contact glass, and the hinge pin 24 is rotated about the shaft and moved downward to be in the closed state. At this time, if the original is a thin object such as a thin sheet, the original pressing plate 12 is rotated only about the hinge pin 24 and the original pressing plate 12 is brought into close contact with the contact glass without being lifted from the contact glass. Further, since it is prevented as much as possible that the external light enters the inside of the apparatus main body 11 and the exposure is prevented, the original can be copied satisfactorily.

  Further, when the original is thick like a book, when the opened original pressure plate 12 is rotated in the closing direction, the original pressure plate 12 is not in a closed state, that is, the original pressure plate 12 is attached to the main body of the apparatus. Prior to being substantially parallel to the upper surface (contact glass), the original cover 12 comes into contact with the end of the original, and there is a space between the end opposite to the end of the original and the original cover 12. It is formed. That is, the document crimping plate 12 is in a state where the end opposite to the document crimping plate opening / closing device body 2 is lifted. The original pressure plate 12 on the floating side is pressed against the device main body 11 side, or the weight 3 of the original pressure plate 12 moves in the direction (upward) in which the leg 3 comes out of the mounting hole 15, and the original pressure plate opening / closing device main body 2 moves upward, and the original cover 12 rotates about the hinge pin 24 as an axis. That is, the height of the document crimping plate opening / closing device body 2 is automatically adjusted so as to cover the upper part of the document, and the document crimping plate 12 moves (see, for example, FIG. 5). For example, when the upper part of the original is a flat surface, the original cover 12 contacts the upper part. As a result, a thick original is stably adhered to the contact glass. Therefore, the original cover 12 can stably adhere the original to the contact glass regardless of the thickness of the original.

  Thus, when the leg portion 3 moves in the height direction in the mounting hole 15, the two roller members 6 provided on the both side walls 15 a of the mounting hole 15 are guided to the guide grooves 5 of the leg portion 3, respectively. Therefore, the movement of the leg part 3 is reliably and smoothly performed. Even if the leg 3 of the original cover 12 is removed from the mounting hole 15, the lower roller member 6 does not engage with the terminal end 51 of the guide groove 5 and come out of the mounting hole 15 of the leg 3. Therefore, the first document crimping plate opening / closing device 1 and the office equipment 10 according to the present invention can move the leg portion 3 smoothly and the leg portion 3 does not come out of the mounting hole 15.

In the first document crimping plate opening / closing device described above, the guide groove 5 is provided on each side surface 3a of the leg 3 and the roller member 6 is provided on each side wall 15a of the mounting hole 15, respectively. For example, as shown in FIG. 15, the guide groove 55 is provided so as to penetrate the both side surfaces 3 a of the leg portion 3, and the roller member 65 is penetrated through the guide groove 55, and both ends thereof are attached to the mounting holes 150. You may make it attach to both the side walls 150a. Specifically, the guide groove 55 is provided from the upper side to the lower side of the side surface 3a of the leg portion 3 so as to penetrate the both side surfaces 3a. This end of the lower guide groove 55, the roller member 65 is formed as a terminal portion 56 for preventing leakage out of the leg portion 3 engages.

  The roller member 65 includes, for example, a shaft 66 whose both ends are attached to both side walls 150 a of the attachment hole 150, and a roller portion 67 that is rotatably supported around the shaft 66. The roller portion 67 is shorter than the dimension between both wall portions of the guide groove 55, for example, has a slightly shorter diameter. When the leg portion 3 is moved along the mounting hole 150, the roller portion 67 is moved in the guide groove 55. The leg 3 can move smoothly while rotating. On the outer periphery in the vicinity of both ends of the shaft 66, for example, mounting grooves 66a for mounting the E ring 68 are provided.

  The mounting hole 150 is formed by a U-shaped mounting hole forming member 160, for example. The attachment hole forming member 160 is formed, for example, by bending a sheet metal into a U shape. Both end portions of the mounting hole forming member 160 are bent outward and formed as flange portions 160a. The attachment hole forming member 160 is provided with a through hole 160 b for attaching the roller member 65.

  The roller member 65 is assembled by first inserting the leg portion 3 into the mounting hole forming member 160 that forms the mounting hole 150 while the roller portion 67 is positioned in the guide groove 55 of the leg portion 3. 67 and the through hole 160b are aligned with each other. The shaft 66 is inserted through the through hole 160b and the roller portion 67 to penetrate therethrough. By attaching the E-rings 68 to the mounting grooves 66a at both ends of the shaft 66 protruding from both sides of the mounting hole forming member 160, the roller member 65 is assembled with the roller member 65 engaged with the guide groove 55. . Thereby, there exists an effect similar to the above, the movement of the leg part 3 can be performed smoothly, and the leg part 3 does not come out of the attachment hole 150.
