Claims

[Scope of Claim for Utility Model Registration] (1) The leading edge of a case is inserted into and supported by the paper feed tray mounting portion of a copying device, and paper is accommodated by the paper feeding mechanism of the copying device located at the top end of the case. In the paper feed tray that feeds the paper one sheet at a time to the copying machine,
A width size regulation mechanism that allows stepless adjustment of the width direction spacing of the paper storage section, which is formed by providing a pair of regulation frames on the inside of both side walls of a flat box-shaped case via a facing distance expansion/contraction adjustment means, and the case. A press plate that is vertically slidable is installed inside the rear wall via a stepless position adjustment means that fixes it at a moving position, and the length of the paper storage section is made stepless adjustable in its rear end support position. A paper feed tray for a copying device, characterized by comprising a size regulation mechanism. (2) The width size regulation mechanism has a structure in which a pair of regulation frames are screwed together in symmetrical positions to a screw shaft whose screw direction is reversed at the center of the shaft installed in the width direction of the case, and the screw shaft is rotated. A paper feed tray for a copying machine according to claim 1. (3) The length size regulating mechanism supports the movable member in a slidable manner with respect to the guide shaft, and has a structure in which the sliding member pivotally mounted on the movable member elastically protrudes toward the guide shaft. A paper feed tray for a copying machine according to claim 1. (4) The width size regulation mechanism and/or the length size regulation mechanism supports an adjustment regulation plate pivotally attached to the end of an adjustment screw screwed into the movable member inside the movable member, and also connects the movable member to the case. 2. The paper feed tray for a copying machine according to claim 1, wherein the paper feed tray is selectively fixed at a plurality of predetermined mounting positions between the paper feed trays.
