摘要

PROBLEM TO BE SOLVED: To measure the size and weight of a delivery with a post-processing device attached to an image formation apparatus.SOLUTION: A post-processing device comprises a sorting sheet discharge tray for discharging a sheet subjected to post-processing in a manner capable of being ascending/descending on the upper part, a placement tray on which a delivery is placed fixed to the lower part, and height measurement means 18 which defines a distance between both trays at the time when the sorting sheet discharge tray descends to be in contact with the delivery on the placement tray as the height of the delivery. The placement tray includes weight measurement means 19 which measures the weight of the loaded delivery, and depth measurement means 20 which measures the depth of the loaded delivery. The sorting sheet discharge tray includes width measurement means 22 which measures the width of the delivery on the placement tray.SELECTED DRAWING: Figure 5
