PAPER POST-TREATMENT DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a paper post-treatment device enhancing alignment property by reducing turbulence of a paper ejected to a paper ejection tray. SOLUTION: The post-treatment device is provided with a conveying part for receiving the paper fed from an image forming device and conveying it to the post-treatment part; a paper ejection part for leading the paper via a post-treatment part to an ejection port; a paper ejection tray 16 for storing the paper ejected from the ejection port 70 and made movable such that the uppermost surface of the stored paper becomes a first height position lower than the ejection port and a second height position nearer the ejection port side than the first height position; and a control part for determining the kind of job of the post-treatment to control the height position of the paper ejection tray 16 and variably controlling a receiving position of the paper such that it becomes the first height position in the case of the job for ejecting the paper one by one and it becomes the second height position in the case of the job for ejecting the paper in a bundle state.
