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.

When the image and the additional image are superposed, the superposition of the image and the additional image is avoided by either reducing the image or changing the position of the image to be formed.
