AI Technical Summary

Technical Problem

When the sheet transport speed is increased to improve productivity in image forming systems, sheets tend to be discharged forcefully, leading to disorder in the stacking position at the discharge destination.

Method used

A sheet discharge device with a loading section, a first transport means, a discharge means, and a control means that adjusts discharge speed based on the number of sheets in a bundle, allowing for controlled discharge of sheets as bundles to improve loading efficiency.

Benefits of technology

The solution enhances sheet loading capacity by aligning and stacking sheets efficiently, reducing disorder and improving productivity without compromising discharge speed.

Abstract

To improve a stacking performance of ejected sheets.SOLUTION: A sheet ejection device sets an ejection rate at which a sheet is ejected by ejection means as follows: an ejection rate set when a sheet bundle is a first number of sheets is set as a first ejection rate, and an ejection rate set when the sheet bundle is a second number of sheets larger than the first number of sheets is set as a second ejection rate that is slower than the first ejection rate.SELECTED DRAWING: Figure 9
