Claims

[Scope of Claim for Utility Model Registration] (1) A front tray fixed in the copying machine main body, a closed position in which the front tray is slid in the paper feeding direction and overlapped with the front tray, and a front tray that is pulled out from the copying machine main body. A drawer-shaped rear tray that is movable between the open position and the front end is fixed to the upper surface of the bottom plate of the front tray, and in the open position of the rear tray, the rear end reaches near the rear end of the rear tray bottom plate to form a horizontal plane. It has a bottom plate that is bent and folded into a U-shape when the rear tray is in the closed position.
A paper feed tray that feeds paper while being held in a bent shape, and a paper feed tray that is provided above the paper feed tray and can be brought into contact with and separated from the transfer position of the photoreceptor, and that is in contact with the paper feed tray. A copying machine having a conveying unit capable of conveying paper fed from a photoconductor by bringing it into contact with a transfer position of a photoconductor, wherein the rear tray is provided with a cam extending in the direction of movement thereof, and the conveying unit is provided with a cam extending in the direction of movement of the rear tray; A cam follower is provided that engages with the cam, and the cam has a shape such that when the rear tray is closed, the transport unit is brought into contact with the photoreceptor, and when the rear tray is opened, the transport unit is retracted from the photoreceptor. A copying machine characterized by certain things. (2) The above paper feed trays are provided in multiple stages in the vertical direction, and the above cam is provided only on the rear tray of the top paper feed tray, and the paper feed trays in the second and lower stages from the top are placed directly above it. 2. The copying machine according to claim 1, further comprising means capable of locking the paper feed tray so as to move integrally with the rear tray. (3) The copying machine according to claim 2, further comprising means for releasing the locking means by housing the rear tray within the copying machine main body.
