摘要:
An image forming apparatus including an image forming device and a post-processing device having a punching device that forms punch holes of a plurality of types to a paper ejected from the image forming device. The image forming apparatus also includes an indicator. The indicator indicates one of pictographs corresponding to each of punch hole types and indicates an indicated pictograph as a pictograph different from the previous pictograph when the indicated pictograph is selected. Or alternatively, the indicator indicates each of the punch hole types and also indicates a plurality of pictographs different from each other and indicates a pictograph corresponding to a selected punch hole type as a pictograph different from the previous pictograph when the punch hole type is selected.
摘要:
A sheet finishing apparatus including a sheet tray, a pair of jogging fences, and a case. The sheet tray stacks a plurality of sheets that have been sent from an image forming apparatus. The pair of jogging fences hold the sheets stacked in the sheet tray and jog the sheets in a transverse direction relative to a sheet transferring direction. The jogging fences are moved toward and away from each other. The case encloses the apparatus and includes a plate covering the sheet tray from an operator accessible side. The plate has an opening. When the pair of jogging fences is expanded to outward limits, one of the pair of jogging fences at the operator accessible side is passed by the plate through the opening and located at an outside position relative to the plate.

A novel output sheet handling apparatus includes outlets, ejection trays, a tray switching mechanism, an outlet switching mechanism, and a controller. Each of outlets ejects a recording sheet. The outlets include at least one straight outlet configured to eject a recording sheet and to eject no stack of recording sheets processed in a complex finishing mode. The ejection trays, at least same plurality as the plurality of outlets, include at least one ejection tray configured to receive the recording sheet from at least two outlets among the outlets. The tray switching mechanism performs a tray switching operation for switching one of the ejection trays in operation to another. The outlet switching mechanism performs an outlet switching operation for switching one of the outlets in operation to another. The controller performs a control operation for controlling the tray and outlet switching mechanisms to minimize a total distance which one of ejection trays in operation and another one are moved during the ejection tray switching operation in accordance with a finishing mode selected when the large capacity ejection mode is selected.

A sheet finisher of the present invention includes jogger fences for jogging sheets sequentially stacked in a stapling section, and a stapler for stapling the sheets together. A CPU (Central Processing Unit) controls a jogger motor such that the jogger fences each move to a first position, a second position, and a third position in accordance with the width of sheets in a direction perpendicular to the direction of sheet conveyance. The first position is remote from the edge of a sheet stack in the direction of the width by a preselected amount. The second position is closer to the edge than the first position by a preselected amount and slightly overlaps the edge. At the third position, when the stapler staples the sheet stack, the jogger fence substantially contacts the edge in accordance with the width.

A sheet aligning device includes a transport path, a movable fence, a tapping tab, and jogger fences. The transport path transports a sheet stack. The movable fence and the tapping tab align the sheet stack in a first direction in which the sheet stack is transported on the transport path. The jogger fences align the sheet stack in a direction perpendicular to the first direction on the transport path. The movable fence, the tapping tab, and the jogger fences align the sheet stack according to a plurality of aligning modes.

A sheet conveying device includes a first conveying path configured to pass a sheet of a recording medium (e.g., paper) therethrough to a sheet processing device, a second conveying path branched from the first conveying path and configured to temporarily store the paper sheet conveyed therein, a sheet conveying mechanism configured to selectably convey the paper sheet in one of forward and backward directions to the sheet processing device, a guide member mounted at a branch point of the first and second conveying paths and configured to guide the paper sheet when the paper sheet is conveyed in the backward direction by the sheet conveying mechanism to the second conveying path, and a control unit configured to control the sheet conveying mechanism to change a distance between the branch point and the sheet conveying mechanism according to a length of the paper sheet in a forward sheet conveying direction.
摘要:
A perforating apparatus comprising a structure in which replacement can be easily conducted corresponding to the perforation conditions such as the punch holes and number of holes, and in which condition settings and position determination can be automatically recognized during replacement; the perforating apparatus comprises: an orientation correction device that corrects skewing and aligns the front edge by striking the front edge of the paper, a perforation device comprising a punch to conduct perforation processing on the paper; and a lateral registration adjustment device that can adjust, in a direction at a right angle to the direction of movement of the aforementioned paper, the position of the perforation device punch in relation to the paper with orientation corrected using an orientation constraint device prior to perforating by the perforation device, the perforating apparatus comprising a structure in which said perforation device can be inserted into and detached from a non-moving support unit comprising the drive source of a lateral registration adjustment device, and when mounted, the type of perforation device can be recognized.
