And a supporting member for supporting the original pressing plate at a place where the two side plates are arranged on both sides of the upper plate, and the two side plates are attached to both side plates of the mounting member so as to be rotatable by a hinge pin. An elastic means composed of, for example, a compression spring elastically bonded between the member and the support member is provided.

This elastic means is inherently supported so that it does not fall naturally even if you release the original pressing plate with a predetermined opening angle range (about 20 ° to 60 °) so as to open and close without feeling its weight upon opening the original pressing plate. It has a function.

However, a change in elastic force over time is inevitable and the elastic adjustment means is provided because it hinders the above-mentioned function.

Most of these elasticity adjusting means are disclosed in Patent Literatures 1 and 2 described below, and use the tool such as a driver in the axial direction of the elastic means to adjust the abutment member abutting on one end side of the elastic means. By controlling the effective length of the elastic means by moving to adjust the elastic force.

However, if the elastic adjustment means of such a configuration, there is a problem that the adjustment operation is difficult to perform because the original compression plate opening and closing device must be removed from the apparatus body or the original compression plate.

Thus, it is known that this adjustment can be performed from the front of the office equipment, and disclosed in Patent Document 3 described below.
