Claims

[Claims for Utility Model Registration] 1. In order to bind the recording paper discharged from the image forming apparatus, after aligning the recording paper at a certain position on the recording paper receiver of the stapling unit, the edge of the recording paper is In an image forming post-processing device that binds a stack of recording sheets using a stapling device and discharges the bound stack of recording sheets to a paper ejection tray, a paper ejection belt is provided to directly connect the stapling section and the ejection tray. and a gripping means protruding from a midway portion of the paper ejection belt so as to lock the binding side of the bound stack of recording sheets, and a gripping means protruding from the middle of the paper ejection belt so as to hold the binding side of the bound stack of recording sheets; An image forming post-processing device comprising: a paper ejection control section configured to adjust the paper feeding speed by the gripping means of the paper ejection belt based on the above-mentioned paper ejection belt gripping means. 2. In the image forming post-processing apparatus according to claim 1, the paper ejection control unit includes a control unit that controls the paper ejection control unit to release the paper by the gripping means of the paper ejection belt when the number of recording paper sheets on the recording paper tray reaches a set value. An image formation post-processing device characterized by being equipped with a speed conversion circuit that increases the feed speed. 3. In order to bind the recording paper discharged from the image forming apparatus, the recording paper is aligned at a certain position on the recording paper receiver of the stapling unit, and then the ends of the recording paper are stapled with a stapling device, and this binding is performed. In an image forming and post-processing device that discharges a bundle of recorded paper onto a paper output tray, the paper output belt is stretched to directly connect the stapling section and the output tray, and the bound recording paper is a gripping means protruding from an intermediate portion of the paper ejection belt so as to lock the binding side of the bundle; 1. An image forming post-processing device comprising: a paper ejection control section configured to adjust the paper feeding speed by the gripping means. 4. In the image forming post-processing device according to claim 3, the paper ejection control section is configured to control the paper feed by the gripping means of the paper ejection belt when the size value of the recording paper on the recording paper tray reaches a set value. An image formation post-processing device characterized by being equipped with a speed conversion circuit that increases the speed.
