SHEET PROCESSOR AND IMAGE FORMING DEVICE PROVIDED WITH THIS SHEET PROCESSOR

摘要

PROBLEM TO BE SOLVED: To realize a sheet processor improving visibility of a sheet loaded onto a plurality of trays arranged in the vertical direction to be made vertically movable, and attaining facilitation of handling. SOLUTION: Of a sample tray 201 and stack tray 200 arranged in the vertical direction to be made vertically movable, when discharging of a sheet P to the downward stack tray 200 is ended, the upward sample tray 201 is moved upward, a space between both the trays 200, 201 is spread. In this way, visibility of the sheet on the downward stack tray 200 is improved, also taking out of the sheet is facilitated, handling workability is improved.
