Abstract

Above a processing tray, a standby tray for making sheets of paper P stand by is installed. The sheets of paper P on the standby tray are dropped, fed, and moved to the processing tray, thus the conveying path from the standby tray to the processing tray is shortened. The standby tray is given a tilt angle of θ1 and the consistency is improved by the own weight of the sheets. A first and a second paper ejection tray are given a tilt angle of θ2 and the consistency is improved by the own weight of the sheets or a sheet bundle.

Claims

1. A sheet post-process apparatus comprising:

a standby tray for making sheets ejected from an image forming apparatus stand by and having a tilt angle of θ

1 at which front ends of said sheets are positioned higher than rear ends of said sheets,

a processing tray arranged under said standby tray for loading said sheets dropped and fed from said standby tray and/or said sheets ejected from said image forming apparatus not via said standby tray,

a processing mechanism for post-processing said sheets loaded on said processing tray, and

a paper ejection tray for at least loading said sheets ejected from said processing tray after ending of said post process and having a tilt angle of θ

2 at which said front ends of said sheets are positioned higher than said rear ends of said sheets.

2. A sheet post-process apparatus according to claim 1, wherein said processing mechanism is a stapler for bundling said plurality of sheets loaded on said processing tray.

3. A sheet post-process apparatus according to claim 1, wherein said processing mechanism is a hole puncher for making a hole in said sheets loaded on said processing tray.

4. A sheet post-process apparatus according to claim 1, wherein said tilt angle θ

1 of said standby tray and said tilt angle θ

2 of said paper ejection tray have a relation of θ

5. A sheet post-process apparatus according to claim 1, wherein said processing tray has a tilt angle of θ

3 at which said front ends of said sheets are positioned higher than said rear ends of said sheets and said tilt angle θ

1 of said standby tray, said tilt angle θ

3 of said processing tray, and said tilt angle θ

2 of said paper ejection tray have a relation of θ

2.

6. A sheet post-process apparatus according to claim 1, wherein said standby tray is composed of at least a pair of tray members for respectively supporting both sides of said sheets and slides and moves said tray members to drop and feed said sheets onto said processing tray.

7. A sheet post-process apparatus according to claim 1, wherein said standby tray is composed of at least a pair of tray members for respectively supporting both sides of said sheets and rotates and moves said tray members to drop and feed said sheets onto said processing tray.

8. A sheet post-process apparatus according to claim 1, wherein said paper ejection tray can load said sheets ejected from said standby tray not via said processing tray.

9. A sheet post-process apparatus comprising:

standby means for making sheets ejected from an image forming apparatus stand by and having a tilt angle of θ

1 at which front ends of said sheets are positioned higher than rear ends of said sheets,

loading means arranged under said standby means for loading said sheets dropped and fed from said standby means and/or said sheets ejected from said image forming apparatus not via said standby means,

processing means for post-processing said sheets loaded on said loading means, and

paper ejection means for at least loading said sheets ejected from said loading means after ending of said post process and having a tilt angle of θ

2 at which said front ends of said sheets are positioned higher than said rear ends of said sheets.

10. A sheet post-process apparatus according to claim 9, wherein said processing means is stapling means for bundling said plurality of sheets loaded on said loading means.

11. A sheet post-process apparatus according to claim 9, wherein said processing means is hole punching means for making a hole in said sheets loaded on said loading means.

12. A sheet post-process apparatus according to claim 9, wherein said tilt angle θ
