Sheet post-process apparatus

1. A sheet loading method, comprising:
- conveying sheets along a sheet conveying direction via a pair of waiting tray parts which support the sheets, the waiting tray parts arranged at an interval in a transverse direction orthogonal to the sheet conveying direction;
applying, via a strike down member, a downward force on the sheets to make the sheets bend and fall down from the pair of waiting tray parts;
retaining, via a distal end upper face retainer, a distal end upper face of the sheets on the pair of waiting tray parts when the interval widens from a first width smaller than a width of the sheets orthogonal to the sheet conveying direction for loading the sheets to a second width larger than the width of the sheets;
allocating a rotary shaft in association with the distal end face in the sheet conveying direction;
rotating the distal end upper face retainer and the strike down member coaxially with a rotary shaft, that is mounted coaxially therewith, when the sheet discharger is projected on a horizontal plane, a discharge direction of the sheet discharger being parallel to the sheet conveying direction;
receiving, via a receiving tray, the sheets fallen from the pair of waiting tray parts; and
discharging, via a sheet discharger, a bundle of sheets to which a post-process has been performed, from the receiving tray.

Abstract
A sheet post-process apparatus includes a waiting tray and a processing tray. The waiting tray is provided in the middle of a conveying path and makes standby sheets in the case where a post-process is required. The processing tray has a function which causes the sheets made standby on the waiting sheet to be dropped by self-weight. With this function, the processing tray receives the sheets moved to be dropped and the sheets conveyed from the conveying path without intervening the waiting tray, before carrying out the post-process. Sheet bundles formed on the processing tray are stacked on a storage tray by a sheet conveying mechanism after they have been post-processed.
