Abstract: A waiting tray is provided in a sheet-conveying path and holds sheets if the sheets need to be post-processed. A processing tray receives sheets conveyed from the waiting tray. It may receive sheets conveyed through the sheet-conveying path and coming not via the waiting tray, before the sheets are post-processed. A conveying mechanism is provided, which causes the sheets to fall, due to gravity, from the waiting tray onto a processing tray. A sheet-aligning mechanism aligns the sheets on the processing tray, at their transverse edges and longitudinal edges. On the processing tray, the sheets are post-processed, forming a bundle. The conveying mechanism conveys the bundle of sheets to a storage tray. The storage tray and the waiting tray are positioned, providing a gap between the waiting tray and the upper surface of the bundle of sheets held on the storage tray.

Abstract: A sheet post-process apparatus of the present invention has a standby tray for stably dropping sheets of paper onto a processing tray, so that a pair of tray members for loading ejected sheets of paper is formed so as to project from the wall face of the standby tray and the loading face of sheets of paper is narrowed from the front end side of the sheets of paper toward the rear end side thereof.

Abstract: Above a processing tray, a standby tray for making sheets of paper P stand by is installed. The sheets of paper P on the standby tray are dropped, fed, and moved to the processing tray, thus the conveying path from the standby tray to the processing tray is shortened. The standby tray is given a tilt angle of ?1 and the consistency is improved by the own weight of the sheets. A first and a second paper ejection tray are given a tilt angle of ?2 and the consistency is improved by the own weight of the sheets or a sheet bundle.

Abstract: A sheet post-process apparatus of the present invention, when sending sheets of paper collected on a standby tray to a processing tray, has a standby tray realizing an improved lining capacity of sheets of paper and a pair of tray members for loading ejected sheets of paper is formed so as to project from the wall face of the standby tray.

Abstract: A waiting tray is provided in a sheet-conveying path and holds sheets if the sheets need to be post-processed. A processing tray receives sheets conveyed from the waiting tray. It may receive sheets conveyed through the sheet-conveying path and coming not via the waiting tray, before the sheets are post-processed. A conveying mechanism is provided, which causes the sheets to fall, due to gravity, from the waiting tray onto a processing tray. A sheet-aligning mechanism aligns the sheets on the processing tray, at their transverse edges and longitudinal edges. On the processing tray, the sheets are post-processed, forming a bundle. The conveying mechanism conveys the bundle of sheets to a storage tray. A gap is provided between the lower surface of the waiting tray and a nip between sheet-feeding rollers that are positioned upstream of the waiting tray and are included in the plurality of rollers.

Abstract: A processing tray comprises a transport belt which transports a sheet, and a push feed arm mounted to be projected onto a surface on a sheet transport side of the belt, the arm retaining a sheet distal end so that the sheet distal end can be pushed and fed, wherein the transport belt forms a through hole through which the push feed arm penetrates, and the push feed arm comprises a push feed face which pushes and feeds the sheet distal end, a penetrating projection portion which reaches a transport belt lower face from the push feed face through the through hole, and a hook shaped engagingly lock portion engagingly locked on the belt lower face after being bent from the penetrating projection portion to the transport belt traveling direction.

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.

Abstract: A waiting tray is featured in that left and right lower face support members and for supporting left and right lower faces of a sheet transport direction are rotatably mounted on both of side frames and via rotary shafts and, and the left and right lower face support members are rotated downwardly or upwardly to release a standby state of a sheet retained on the waiting tray in a waiting mode.

An opening is provided between the waiting tray and the processing tray and located at downstream of the waiting tray and processing tray.

Abstract: A waiting tray comprises left and right lower face support members for supporting a sheet. These support members are formed so that a width of an opening portion formed therebetween is wide at a distal end side as compared with a proximal end side in a transport direction of a sheet to be transported to the waiting tray. When the sheet which is not required to be retained in a waiting mode is transported to the waiting tray, at a time point when the sheet distal end reaches the waiting tray, both of the support members are opened to an extent such that the width of the opening portion of the left and right lower face support members is narrower than a sheet width at the proximal end side in the transport direction of the sheet, and is wider than the sheet width at the distal end side of the sheet. In this manner the sheet is dropped from the sheet distal end to the processing tray immediately without being retained in a waiting mode.
