Abstract:
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 bundled sheets; and a storage tray which holds the bundles of 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 shaft which rotatably supports one side face of the left and right lower face support members; and a motor that rotates the left and right lower face support members upwardly or downwardly while the shaft is defined as a rotation center, thereby releasing retention of the sheets, wherein the processing tray and the waiting tray are shorter in length in the sheet transport direction thereof than a length of a standard sheet to be held, and wherein a part of a proximal end side in the sheet transport direction of the sheet to be held on the processing tray is held on the storage tray.
