Embodiment 1

[0046] Figure 1 to Figure 5 It is a figure which shows an example of the document platen opening and closing apparatus of this invention. like figure 1 As shown, the document platen opening and closing device 1 of the present invention is a device in which the document platen 12 is rotatably attached to the rear upper surface of the device main body 11 of the office device 10 . Although it does not specifically limit as office equipment 10, For example, a copier, a printing machine, a facsimile machine, a scanner etc. are mentioned, and a copier is mentioned as a preferable example, but it demonstrates unless it is specifically limited. In addition, as shown in the figure, a pair of document platen opening and closing devices 1 are generally used, and the device for opening and closing the document platen 12 with the automatic document feeder 12a is equipped with a heavy automatic document feeder on the left side because it faces the front. 12a, so the left and right struct...

Embodiment 2

[0087] Figure 15 and Figure 16 Another embodiment of the document platen opening and closing device is shown. According to the drawings, in the document platen opening and closing device 99 of this embodiment, one of the components existing at both ends of the elastic member 100 is the cam slider 104, and the other is the cam slider 104. One is the sliding body 107, the cam sliding body 104 is configured to be slidably surrounded by the support member 101, and the front end is in contact with the pressure receiving member 103 mounted on the mounting member 102, and the sliding body 107 is also configured to be slidably supported by the member 101 is surrounded by and in sliding contact with the working member 106 mounted on the free end side of the lifting member 105, and the elastic force adjusting member 108 of the middle-diameter compression coil spring 100b in the inner side of the large-diameter compression coil spring 100a among the elastic members 100 is mounted on the ...

Embodiment 3

[0089] In the case of the third embodiment, the original platen opening and closing device 111 may be configured to omit the sliding body 107 in the previous embodiment 2, and as shown in FIG. An elastic member 115 is elastically provided between the top plate 112b and the cam slider 114 provided on the attachment member 113 side. Furthermore, an elastic force varying member A is provided in the compression coil spring constituting the elastic member 115 . Furthermore, the number and diameter of the compression coil springs are not limited by the embodiments. Further, regarding the damping member 119, there are cases where the member is provided and cases where the member is not provided. Also, the parts with the same reference numerals represent the same parts as those in the second embodiment.

[0090]In the case of the third embodiment, the lift member 118 is attached to the free end side of the support member 112 by the second hinge pin 117 , so that the torsion spring 1...
