AI Technical Summary
Technical Problem
Existing sheet processing devices face challenges in maintaining sheet alignment during discharge while minimizing collision noise between pressing members and retractable trays.
Method used
A mechanism combining a pressing member and a retractable tray, where the retractable tray supports the sheet bundle from below after it abuts the pressing member, controlled to avoid direct collision, ensuring alignment and reducing noise.
Benefits of technology
Simultaneously improves sheet alignment and reduces collision noise by coordinating the movement of the retractable tray with the pressing member's contact, enhancing discharge stability.

Abstract
To provide an improved mechanism that balances between the improved alignment of sheets by combining a holding member with an ejector tray and the reduction of crash noise caused by their collision.SOLUTION: The sheet processing device includes: discharge means for discharging a bundle of sheets conveyed along a conveyance path from an outlet; loading means for loading the discharged bundle of sheets; contacting means located on the front in the discharge direction of the bundle of sheets from the outlet and abutting the upper surface of the discharged bundle of sheets; support means configured to be retractable from the outlet and to temporarily advance under the bundle of sheets and support the bundle of sheets when the bundle of sheets is discharged; and control means which controls the movement of the support means so that the support means reaches the position of the contacting means after the bundle of sheets abuts the contacting means.SELECTED DRAWING: Figure 1
