<p>PROBLEM TO BE SOLVED: To facilitate a work, such as processing of a jam of paper sheets, wherein when a paper discharging device is opened, transfer papers accumulated on a paper discharge tray are prevented from being dropped on a ground and the order of paper discharge is prevented from miscarrying. SOLUTION: Since, when a paper discharge tray 35 is attached to the upper stage part or the lower stage part of a paper discharge device 34, the hook part 35a of the paper discharge tray 35 moves an upper stage control plate 53 or a lower stage control plate 55 to the right, even when rotation is effected in the direction of an arrow mark F, the upper protrusion part 50a of a hook 50 and the protrusion part 53b of the upper stag control plate 53 or the lower protrusion part 50b of the hook 50 and the protrusion part 55b of the lower stage control plate 55 are brought into contact with each other, whereby rotation of the hook 50 is blocked. When the paper discharge tray 35 is removed together, since the upper stage control part 53 and the lower stage control plate 55 are both moved to the left, rotation of the hook 50 is practicable.</p> |
