Abstract

In a sheet post-process apparatus of the present invention, a processing tray for loading sheets of paper fed via a standby tray for making ejected sheets of paper stand by or not via the standby tray and a standby tray roller for performing a first operation of making contact with sheets of paper loaded on the standby tray and matching and a second operation of making contact with sheets of paper loaded on the standby tray and conveying them toward a paper ejection tray are installed in the neighborhood of the standby tray.

Claims

1. Sheet post-process apparatus comprising:

a standby tray for making sheets ejected from an image forming apparatus stand by,

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

a standby tray roller for performing a first operation matching said sheets loaded on said standby tray in contact with said sheets and a second operation conveying said sheets loaded on said standby tray toward said paper ejection tray in contact with said sheets.

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

said standby tray roller, when dropping said sheets loaded on said standby tray onto said processing tray, performs a third operation shifting upward.

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

said standby tray roller can move vertically.

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

said standby tray roller is driven to rotate by a standby tray roller motor

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

said standby tray has said standby tray roller.

6. A sheet post-processing method of a sheet post-process apparatus for post-processing sheets ejected from an image forming apparatus, comprising the steps of:

making said sheets ejected from said image forming apparatus stand by on a standby tray,

loading said sheets fed from said standby tray and/or ejected from said image forming apparatus not via said standby tray on a processing tray,

post-processing said sheets loaded on said processing tray,

loading said sheets after ending of said post process on a paper ejection tray, and ‘

selecting a first operation matching said sheets loaded on said standby tray in contact with said sheets and a second operation conveying said sheets loaded on said standby tray toward said paper ejection tray in contact with said sheets.

7. A sheet post-processing method according to claim 6, wherein:

said standby tray roller, when dropping said sheets loaded on said standby tray onto said processing tray, selects a third operation shifting upward as one selection.
