Sheet post-process apparatus and waiting tray
First Claim
1. A sheet post-process apparatus, the apparatus comprising:
- a waiting tray which temporarily retains a transported sheet in a waiting mode and releases the retention to drop the sheet;
a processing tray which bundles the sheets dropped from the waiting tray to carry out predetermined processing and ejects the sheet; and
a storage tray which holds the bundle of sheets processed and ejected on the processing tray, wherein the waiting tray comprises;
left and right lower face support members which support left and right lower faces in a sheet transport direction during retention in a waiting mode and release the support on the left and right lower faces during release of the retention;
a distal end lower face support member which supports a distal end lower face of the sheet transported to the waiting tray;
a distal end upper face retainer member which retains a distal end upper face of the sheet transported to the waiting tray;
sensor means for sensing that a sheet has been held on the waiting tray; and
driver means for, based on a sense signal of the sensor means, moving the distal end upper face retainer member to a location for retaining the distal end upper face of the sheet transported to the waiting tray.

Abstract
A sheet post-process apparatus comprises left and right lower face support members which support left and right lower faces in a transport direction of a sheet retained by a waiting tray in a waiting mode, distal end lower face support members which support a distal end lower face of the sheet transmitted to the waiting tray, a distal end upper face retainer member which retains a distal end upper face of the sheet transported to the waiting tray, sensor means for sensing that a sheet has been held on the waiting tray, and a drive motor which, based on a sense signal of the sensor means, drives the distal end upper face retainer member in a location for retaining a distal end upper face of the sheet transported to the waiting tray.

4. A waiting tray for use in a sheet post-process apparatus, for temporarily retaining a transported sheet in a waiting mode, followed by releasing the retention, thereby making it possible to drop the sheet onto a processing tray, the waiting tray comprising:
-
left and right lower face support members which support left and right lower faces in a sheet transport direction during retention in a waiting mode and release the support on the left and right lower faces during release of the retention;
a distal end lower face support member which supports a distal end lower face of the sheet transported to the waiting tray;
a distal end upper face retainer member which retains a distal end upper face of the sheet transported to the waiting tray;
sensor means for sensing that a sheet has been sensed on the waiting tray; and
driver means for, based on a sense signal of the sensor means, moving the distal end upper face retainer member to a location for retaining the distal end upper face of the sheet transported to the waiting tray.

9. A sheet post-process apparatus, the apparatus comprising:
-
waiting means for temporarily retaining a transported sheet in a waiting mode and releasing the retention to drop the sheet;
processing means for bundling the sheets dropped from the waiting means to carry out predetermined processing and ejecting the sheet; and
storage means which holds the bundle of sheets processed and ejected by the processing means, wherein the waiting means comprises;
left and right lower face support means for supporting left and right lower faces in a sheet transport direction during retention in a waiting mode and releasing the support on the left and right lower faces during release of the retention;
distal end lower face support means for supporting a distal end lower face of the sheet transported to the waiting means;
distal end upper face retainer means for retaining a distal end upper face of the sheet transported to the waiting means;
sensor means for sensing that a sheet has been held on the waiting tray; and
driver means for, based on a sense signal of the sensor means, moving the distal end upper face retainer member to a location for retaining the distal end upper face of the sheet transported to the waiting tray.
