Further, the symbols 8f, 8f, ... in Fig. 10(c) are assembly holes.

Further, in the original plate opening device B of this type, the main cause of finger pinching is that the original platen C is attached to the apparatus body a when the original platen C is assembled to the apparatus body a, and the original platen C is opposed to the apparatus body a at the time of conservative inspection. When performing disassembly and assembly work and adjusting the original platen C When assembling the position. In the above-described case, the original pressure plate C is assembled by the original pressure plate opening device B, and the original pressure plate opening device B is held by both hands. In a state in which the original pressing plate C is assembled in the embodiment of the document pressing plate B with its lifting member 6, as shown in FIGS. 6 and 7, the original pressing plate C is opened. At this opening angle, the shaft turning moment generated by the rotation of the hinge pin 3 by the original pressing plate C is small. If the original pressing plate opening device B is held by both hands for disassembly or adjustment work, the original pressing plate C is easy to The hinge pin 3 is swayed in the up and down direction (that is, the opening direction) as a fulcrum, and it is easy to cause a finger to be pinched between the assembly member 1 and the support member 2 and the rear portion of the lifting member 6.

In each of the above cases, the present invention can effectively reduce the gap between the assembly member 1 or the stopper member 8 of the assembly member 1 and the support member 2 and the lifting member 6, so that the finger is brought close to the gap to be relatively In the assembly and disassembly work or adjustment work of the assembly body 1 of the device body a, there is no risk of pinching the fingers. That is, in a state where the original pressing plate C is closed, the extending portions 2e and 6d, the protruding portions 8e and 8e of the stopper member 8, and the groove portions 2f, 2f, 6e, 6e provided at the extending portions 2e and 6d, The gap between the assembly member 1 and the support member 2 and the lift member 6 is made small, so that the finger can be prevented from being pinched, and the original press plate C can be subjected to the conservative inspection, repair, and adjustment of the assembly position at the extension portion 2e and 6d, the projections 8e and 8e of the stopper member 8, and the grooves 2f, 2f, 6e, and 6e provided in the extension portions 2e and 6d, even if the portion of the assembly member 1 is held by hand, the assembly member is assembled. 1 or the gap between the stopper member 8 of the assembly member 1 and the support member 2 and the lifting member 6 becomes small, and the finger can be prevented from being caught.

When the original platen C is opened in the state shown in FIGS. 2 to 5, the cam portion 10a is in contact with the holding surface at the abutment position of the pressure receiving member 5 with respect to the cam portion 10a of the cam slider 10. The lower portion moves from the upper portion to the lower portion, so that the original pressing plate C is opened by the elastic force of the elastic means 12 to offset its own weight. When the original pressing plate C of the hand-opening is released, the abutment position of the pressure receiving member 5 is affected by the frictional resistance of the cam portion 10a of the cam slider 10 moving upward, and the cam portion 10a of the cam slider 10 At the same time, the sliding in one direction is reinforced by the elastic means 12, so that the original pressing plate C is transmitted through the supporting member 2 by the rotational moment generated by the hinge pin 3 and the elastic force of the elastic means 12, and the abutting cam member through the pressure receiving member 5 The rotational moments generated by the cam portions 10a of 10 can be balanced with each other. Therefore, the original pressing plate C in the embodiment can maintain a stable still state at an opening angle of 10 degrees or more.

Further, the pin finger preventing means 13 of the present invention is used when the original plate closing device B is assembled to the device body a, or when the assembled position is adjusted after assembly, even if the component of the assembled component 1 is held by hand, it is supported. The element 2 or the lifting element 6 is provided with a stretched portion 2e or 6d at the rear of the back plate 2a or 6a, so that the gap between the original platen opening device B and the rear portion of the assembled component 1 can be reduced while a predetermined original pressure is applied. The opening angle of the plate C sets the projections 8e, 8e on the stopper member 8, wherein the projections 8e are embedded in the grooves 2f, 2f and 6e, 6e provided in the extensions 2e, 6d, thereby effectively preventing the fingers from being pinched There is a risk of injury between the assembly element 1 and the support element 2 or the lifting element 6.

When the original document pressing plate C is closed, the original pressure plate C is affected by the impedance of the pressure receiving member 5 against the elasticity of the elastic means 12 toward the upper portion of the cam portion 10a, and therefore the pressing force of the transmitted hand relative to the original pressing plate C is exerted. The weight of the original platen C and the inertia force are closed. However, when a predetermined closing angle, for example, 10 degrees, is reached, a moment automatically occurs in the closing direction of the original pressing plate C, so that the pressing plate is automatically closed even if the hand is released. Further, at the time of the opening operation of the original pressing plate C, since the pressure receiving member 5 and the cam portion 10a of the cam slider 10 are maintained in the surface contact state, the grease applied to the cam slider 10 is dispersed, and the lubricating grease is also used. It can maintain its holding state, so in addition to preventing excessive weight from being applied to the cam slider 10, even if it is worn out for years, the wear or strange sound generated by the grease is effectively prevented.

At this time, if the pressure member 5 and the sliding portion of the cam portion 10a of the cam slider 10 are provided with the grease filling portion, the ability to maintain the grease can be further improved. The grease filling portion may be disposed at one or both of the pressure receiving member or the cam portion. At the same time, the shape and arrangement position of the grease filling portion are not limited to the above.

When the original is a thick original such as a book, the thick original is carried on the original loading table d (invisible glass) in FIG. 1 and the original pressing plate C is pushed down, as shown in FIG. The two side plates 6b, 6b of the lifting element 6 will rotate with the connecting pin 4 as a fulcrum, so that the spring bearing element 11 is pressed by the actuating element 9 assembled to the two side plates 6b, 6b, against the elastic means 12. While the elastic force slides in the direction of the cam slider 10, the original pressing plate C is rotated with the connecting pin 4 as the axis of the lifting member 6, and horizontally covers the upper surface of the thick original. Therefore, the original plywood opening device B of the present invention can stably press the original on the apparatus main body a regardless of the thickness of the original document, and in particular, in the case of a thick original, it can be prevented as much as possible. The light source is incident from the invisible glass to the exposed portion of the device body.
