Claims

[Scope of Utility Model Registration Claim] A front tray fixed to the main body of a copying machine, and a sliding connection guide member provided on both sides of the front tray to slide the paper in the feeding direction and overlap the paper. a rear tray that can be displaced between a closed position and an open position when pulled out; and an elastic plate whose front end is fixed to the upper surface of the bottom plate of the front tray and which reaches near the rear end of the rear tray in the open position and forms a horizontal plane. One end is connected to both sides of the rear end of the bottom plate, and the other end is fixed and tensioned to a pulley that rotates in conjunction with the opening/closing movement of the rear tray via an intermediate pulley provided near the front end of the front tray and above. In the closed state, the bottom plate is pulled by the wire and curves into a U-shape, allowing the paper placed on the inner surface to be fed, and in the open state, the wire stretches. In the paper feed tray of a copying machine, in which paper can be supplied on a bottom plate stretched out in a horizontal plane, a stack of paper is loaded, so it is difficult to accurately bring the front edge of the paper into contact with the front end wall of the cassette. In the latter case, the paper feed cassette is divided into a front part and a rear part, which are hinged to each other and can be bent 180 degrees to stack the rear part on top of the front part, saving space. Although it is possible to save money, the rear cassette is shaped like a bag, and it is time-consuming to insert the second half of the paper stack into this part and place the first half on the bottom plate of the front of the cassette with the front edges aligned. However, it has the disadvantage that it is cumbersome to operate. In view of the above-mentioned drawbacks of the conventional paper feed tray of the above type, the present inventor proposed a front tray 1 in which the paper feed tray is fixed to the main body of the copying machine, as shown in FIG.
It is slidably connected to this via sliding connection guide members 2 such as AcyuRide (product name) provided on both sides of the copying machine in parallel to the paper feeding direction, and as shown in FIG. It consists of a rear tray 3 that can be moved between the two positions and the closed state in which it is pushed into the copying machine body and overlaps the front tray 1 from below, as shown in FIG. means for causing the wire to slack by a predetermined amount when the rear tray is open; and means for pulling and holding the slack wire in the rear tray to a position substantially along the sliding connection guide member. A paper feed tray characterized by being provided with.
