The compression spring 5 ___ 84 transmits the elastic force of the position of the adjustment disk 84 ^= 18 200921257 5. In addition, a damper device can be disposed in the compression spring 5 (not shown, the damper device is in the closing direction of the original platen 12) When rotating, it is only below the specific rotation angle at an arbitrary rotation angle of the original platen (for example, approximately 1 〇β or less) to slow down the rotation speed of the original platen 12, for example, an oil damping device, etc. The original platen opening and closing device i and the office equipment 1 of the present invention will be described. f The original platen 12 is attached to the original platen glass 13 of the apparatus main body U as shown in Fig. i in a state where the apparatus main body i is not in use. In order to place the original on the original glass 13 'First As shown in FIG. 2, the gripping portion provided at the end portion of the original platen 12 on the side opposite to the portion on which the lifting member 4 is attached is lifted upward, that is, the original pressing plate 12 is lifted. Only the first drum key 15 is rotated about the axis, and the surface of the original platen glass 13 is exposed to the outside. Therefore, when the original platen 12 is rotated, the original platen 12 is biased toward the opening direction of the spring 5 After the original is placed on the exposed original glass 13 # face, the original original platen 12' The closing direction of the cloth is rotated by the first hinge pin 15 and moved downward to be in a closed state. When the original pressing plate 12 is in a closed state, when the original is a thin paper, the original can be prevented from passing through the original pressing plate 12. The table glass 13 floats up and firmly adheres to the original platen glass 13. Therefore, the original can be easily copied or the like, that is, the original platen 12 is in close contact with the original platen glass 13 so that light does not enter the original platen 12 With manuscript 19 200921257 Between the table glasses 13, the original can be easily copied or the like. In addition, when the original is thicker than a book, for example, when the plate 12 is turned in the direction, the wire member of the original plate 12 is turned. A part of the vicinity of 3 is in contact with the bearing member 3 or the like, and the original inspection 12 is floated between the end opposite to the end portion of the original member 3 and the original, and the original sheet glass 13 is lifted. By pressing the side of the manuscript 12 or the weight of the original document 12, the action iron 18 is pressed against the block 6 and resists the elastic force of the compression spring 5, so that the first slider 6 follows the name == (Γ member 4) The second hinge pin 16 is rotated about the axis to cover the upper part of the original document. For example, the upper part of the upper part of the yoke is flattened and the upper part of the yoke 12 is cooked. The money fruit is thickly attached to the original plate _ 13, therefore, Thicker than the manuscript, the 'original domain board 12' allows the original to be stably attached to the original glass, allowing the original to be printed well. In the manuscript plate _ set 1 and the office set (4) of Wen Qian, since the device 8 is installed, the spring of the compression spring 5 can be made: the torque of 3 is the work such as a screwdriver, that is, after the support member, When the work unit is coupled to the block core from the operation recess 83a of the phase, the final adjustment (four) phase = Γ rotation is set with the rotation of the tool, so that the adjustment portion 82 is rotated, so that the portion is moved along the inner portion 82. The axial direction of the elastic material of the first slider 6 accommodates the spring end of the spring spring 5, so that the force changes the length of the change, thereby causing the bomb of the compression cartridge 5 to be prepared. When the directions are rotated, the adjustment disk 84 20 200921257 approaches the operation panel 81, and the operation panel 81 is weakened to another spring load. On the other hand, the direction is moved, thereby ejecting! The adjustment disk 84 is rotated away from the operation panel 81. By changing the spring load like this, it is possible to adjust the spring load relative to the adjustment ^2. When the operation panel 81 is rotated, the long sound change between the both ends due to the adjustment of the disk 84: axial movement 'so the compression spring 5 rides Correctly change the elastic force of the retracting spring 5, so it can be The operation of the operation portion 83 from the through hole 61 of the first slider 6 to the outer tube disk 81 is simple, so that the torque closing device i can be easily disposed in the through hole 61 of the operation operation portion 83. The end portion (closed portion) of the first slider 6 that is opened at the original platen is excellent in operability, and the torque can be easily adjusted in advance. Therefore, the original platen opening and closing device of the present invention is provided. 1 and the office equipment 10 can be adjusted simply and accurately into the chirp, thereby making it simple and correct to prevent jumping or intermediate bending, that is, if the spring load is too strong, the original platen 12 is turned to the opening direction. When the time is 'in the middle of the rotation, the original platen 12 is automatically rotated by the elastic force of the compression spring 5 to cause a so-called beating phenomenon, but the ridge load can be appropriately adjusted, so that the jumping can be prevented simply and surely. In addition, if the spring load is too weak, when the original platen 12 is rotated in the closing direction, the lifting member 4 may resist the elastic force of the compression spring 5 and the second hinge pin 16 as the axis in the middle of its rotation. When the support member 3 is rotated, a so-called intermediate bending phenomenon occurs, but the spring load can be appropriately adjusted, so that the intermediate bending can be prevented simply and surely. As described above, the original platen opening and closing device 12 of the present invention is constructed as follows. There is one operating panel 81 to 21 200921257, at least one adjusting disc 84, - 81 is rotatably disposed on the first slider J: 83, and the operating panel adjusting disc 84 is movably disposed in the axial direction. In the batch adjusting portion 82, the end portion of the compression spring 5 is rotated, and the through hole 61 disposed in the first slider 6 is exposed to the pure=disc 81, and the device is permeable (4). Through-hole of the first-slider 6: the parallel disk 81 rotates, (4) the operation dragon rotates, and adjusts the operation of the ^;=_bu part so that the pressure plate of the office equipment such as the pressure-sliding 5 (four). According to the first aspect of the invention, the original platen opening and closing device of the original plate opening and closing device (four) is provided with an embodiment of the sigh and a side cross-sectional view showing a state in which the original platen is closed.
