PAPER POST-TREATMENT APPARATUS

摘要

PURPOSE:To perform the post-treatment of paper with high accuracy by sufficient matching by setting bin moving timing on the basis of the size of the paper discharged from an image forming apparatus and performing matching even with respect to large size paper in a wide bin interval state by a matching means. CONSTITUTION:The size data or speed data of paper whose image is formed to the receiving processing part 11 of a control part 10 is inputted and a vertical bin moving part 14 and a discharge paper matching part 15 are driven and controlled on the basis of said data by a motor control part 12. At the time of this control, the timing from the detection of paper discharge to the driving start of a drive means is set on the basis of a paper size and the time starting the movement of a bin due to the drive means is set on the basis of a paper discharge speed. By this constitution, sufficient shaking is performed even with respect to paper having a large size to perform paper arrangement and matching is performed in a wider bin interval state with respect to paper slow in its discharge speed and paper post-treatment is enabled with high accuracy.
