Abstract

In a sheet post-process apparatus of the present invention, a gate for branching sheets of paper ejected from an image forming apparatus to a conveying path of sheets of paper requiring a post process and a conveying path of sheets of paper requiring no post process is installed and a paper ejection tray receives either of sheets of paper post-processed and sheets of paper not post-processed.

Claims

1. Sheet post-process apparatus comprising:

a gate for branching sheets ejected from an image forming apparatus to a conveying path of sheets requiring a post process and a conveying path of sheets requiring no post process,

an exclusive paper path of said sheets requiring no post process,

a standby tray for making predetermined sheets among said sheets requiring said post process,

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 loading said sheets ejected from said processing tray after ending of said post process and said sheets requiring no post process.

2. The sheet post-process apparatus of claim 1, wherein:

said gate has a wedge-shaped section.

3. The sheet post-process apparatus of claim 1, wherein:

said gate is rotatably born by an inner side wall of said sheet post-process apparatus.

4. The sheet post-process apparatus of claim 1, further comprising:

a pair of entrance rollers receiving said sheets ejected from said image forming apparatus which are arranged almost at upper and lower positions, wherein said gate takes a first position almost pointing an upper entrance roller and takes a second position almost pointing a lower entrance roller.

5. The sheet post-process apparatus of claim 4, wherein:

said first position is a position for selecting said path requiring said post process and said second position is a position for selecting said path requiring no post process.

6. The sheet post-process apparatus of claim 4, wherein:

when said gate is at said first position, said sheets are sent to said standby tray.

7. The sheet post-process apparatus of claim 2, wherein:

a plurality of paper feed rollers are installed before and after said paper path.
