Sheet post-process apparatus and waiting tray
First Claim
Patent Images
1. A sheet post-process apparatus, the apparatus comprising:
- a waiting tray to temporarily retain a transported sheet in a waiting mode, and release the retention to drop the sheet;
a processing tray to align sheets dropped from the waiting tray to carry out predetermined processing, and eject the sheets; and
a storage tray to hold the 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 of the left and right lower faces during release of the retention;
a distal end lower face support member which retains a distal end lower face in the sheet transport direction during retention in a waiting mode and releases the support of the sheet distal end lower face by moving downward while rotating; and
drive means capable of moving the distal end lower face support member to a location for releasing the support of the distal end lower face from a location for supporting the distal end lower face.

Abstract
A waiting tray comprises left and right lower face support members for supporting both sides of a sheet and a distal end lower face support member for supporting a distal end lower face, wherein, even if a sheet is easily bent, the sheet is reliably retained on the waiting tray, and when a standby state of the sheet is released, release of the support of the left and right lower face support members and release of the support of the distal end lower face support member are carried out.

opening and closing can be freely carried out in a sheet widthwise direction; and
opening is carried out in the sheet widthwise direction, thereby enabling movement from a location for retaining the sheet to a location for releasing the support of the sheet. - View Dependent Claims (7)
