A finisher for finishing a booklet having a bundle of center-folded sheets, includes: a detector for detecting an end on a side of a folded portion of the booklet: a moving device for conveying the booklet by movement thereof; a controller for controlling the movement of the moving device; and a cutting device for cutting an edge on a side opposite to the end of the booklet, which has been conveyed by the moving device to a cutting position. The controller controls the movement of the moving device from a position where the detector has detected the end of the folded portion to the cutting position so that a size of a booklet after being cut is kept constant for each of sheet sizes.

A decurl device includes: a curl detecting section having a plurality of toothed wheels each which detects a curling amount and a curling direction of a sheet having a curl; and a plurality of uncurling sections each arranged downstream of the curl detecting section in a conveyance direction of the sheet having the curl, which uncurls the sheet by bending and transforming the sheet in a direction reverse to a curling direction thereof. One of the uncurling sections, which reduces the curl, is selected on the basis of the curling amount and the curling direction that have been detected by the curl detecting section, thereby uncurling the sheet.

A sheet puncher includes; a reversal conveying section having a displaceable stopping member by which a sheet is stopped at a predetermined position, and punching device; a conveying-in and conveying-out section having a conveying-in device and conveying-out device by which the sheet is conveyed from a main conveying path into the reversal conveying section, and the sheet is conveyed out from reversal conveying section to the main conveying path, wherein the sheet is conveyed into the reversal conveying section by the conveying-in device, and after the sheet is stopped at a predetermined position by the stopping member, the sheet is punched by the punch device, and the conveying direction is reversed by the stopping member and the sheet is carried from the reversal conveying section by the conveying-out device.
摘要:
In a sheet finisher having a stacker for sheets conveyed from an image forming apparatus and a stapler for stacked sheets, the sheet finisher further has a conveying timing adjustment section arranged upstream of the stacker including: a conveying-in section for a sheet from the image forming apparatus; a conveying-out section separately provided from the conveying-in section; and a reversal conveying section for reversing a conveying direction of the sheet conveyed in one direction from the conveying-in section and for conveying-out from the conveying-out section. A controller controls the reversal conveying section such that at least a second bundle or a bundle after the second bundle of sheet bundles to be stapled by the stapler, in which a plurality of sheets having at least a top sheet and a succeeding sheet to the top sheet are overlapped each other, is conveyed-out from the reversal conveying section.
