Abstract: A stacking system for stacking paper from a linear feed.

Abstract: A stacking device includes a drive mechanism coupled to a movable band. The movable band is configured to move along an orbital path, and a twin roller with first and second portions engages the movable band and folds the movable band into at least two portions. In some cases, the drive mechanism can also include, or be attached to, two additional rollers that are inside the band and move along the orbital path. A stacking device may also include a roller set with first and second portions that press against a band. A mechanism may cause the band to orbit along a path such that it causes the band to receive a stackable item and move it to a predetermined location. At the predetermined location, the band releases the stackable item while continuing to orbit along the path, but while having zero total velocity.

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. Furthermore, a Z-folding mechanism is arranged above the standby tray, and the sheets of paper P folded in a Z shape are dropped, and are mixed and stapled on the standby tray or processing tray, and even when performing a plurality of post processes for sheets, miniaturization of a sheet post-process system is retained.

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. A conveyor belt is arranged at an angle with the processing tray so that the front end side of the sheets is positioned higher than the rear end side thereof and the conveyor belt on the front end side of the sheets is projected from the processing tray. By doing this, frictional force of the conveyor belt with the sheets of paper P on the rear end side is made smaller, and frictional force with the sheets of paper P on the front end side is made larger, and the ejectability of sheets from the processing tray after ending of the post process is improved.

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 so that a downward side end in a conveying direction of sheets is oriented upwardly. In the case where a postprocess is required, sheets are made standby. 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. In addition, an upstream side end in a conveying direction of the sheets on the waiting tray and a downstream side end in a conveying direction of the sheets on the processing tray are allocated to overlap on each other in the conveying direction of the sheets.

Abstract: A sheet post-processing device of the present invention includes a jam-disposal mechanism for moving a moving section which is provided opposite to a staple tray to the outside of the device. That is, in the sheet post-processing device, since a portion of the moving section can be moved to the outside, it is possible to form a space in front of the staple tray. Thus, it is easy to perform the jam-disposal by using the space. Further, since the staple tray is not moved in forming the space, consistency of placed sheets is not lost. Further, since it is not required that a space to perform the jam-disposal is prepared inside the device in advance, it is easy to miniaturize the device. Thus, the sheet post-processing device of the present invention is a compact sheet post-processing device by which the jam-disposal can be performed without losing the consistency of a sheet bundle placed on the staple tray.

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 at some midpoint of a conveying path, and a sheet is caused to be in a waiting state when a post-process is required. Before performing the post-process, a processing tray receives the sheet conveyed from the waiting tray and the sheet conveyed from a conveying path without passing through the waiting tray. At this point, waiting tray parts are moved toward a direction in which the waiting tray parts are separated from each other, and a bundle of paper starts fall-down. When the bundle of paper falls down, the waiting tray parts are moved toward the direction in which the waiting tray parts are brought close to each other, and an alignment member performs alignment in a transverse direction of the bundle of paper.

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 control mechanism controls the speed of sheet-feeding rollers provided at upstream of the waiting tray, thereby to the place sheets at a preset position on the waiting tray.

Abstract: A transporting system and method for use in a high velocity document processing system using lower velocity print technology. The invention including an upstream transport conveying spaced apart documents at a first transport velocity. A deceleration transport decelerates documents from the high speed to a lower print velocity before passing the documents a print transport. A sensor located at the deceleration transport, detects the presence of documents at the deceleration transport, and triggers the deceleration profile to be performed on the document. The deceleration transport is controlled such that a leading portion of a document that is being decelerated overtakes a trailing portion of a downstream document that already traveling at the lower print velocity in the control of the print transport. An overlapping arrangement urges the lead portion of the upstream document to overlap on top of the trailing portion of the downstream document when the upstream document overtakes the downstream document.

Abstract: A first shaft 21 and a second shaft 31 parallel with each other are provided near an inlet 14 of a bill storage chamber 10. Taking-in runners 20 are disposed on the first shaft 21 and taking-in rollers 30 are disposed on the second shaft 31. The taking-in runners 20 and the taking-in rollers 30 differ in position in a direction in which the shafts extend. Further, the sum of the radius of each taking-in runner 20 and that of each taking-in roller 30 is larger than the spacing between the first shaft 21 and the second shaft 31. Thus, if a plurality of overlapped bills are caught in the space between the taking-in runners 20 and the taking-in rollers 30, they are bent in a wavy form and the intimate contact force between the bill is lowered significantly, causing the bills to be easily aligned.
