摘要:
A sheet finishing method in which a sheet delivered from an image forming apparatus main body is conveyed and stacked on a sheet placement table, and the stacked sheets are positioned and aligned, and then folded by a folding means composed of a paired folding rollers and a folding plate. The sheet finishing method is controlled such that a rotation motion of the paired folding rollers is switched between a state to be rotated along with an advancing motion of the folding plate and a state to be stopped in accordance with the number of sheets stacked on the sheet placement table.

A sheet finisher includes: a stacking member for aligning a plurality of recording sheets each on which an image has been recorded and for stacking the plurality of recording sheets thereon; a cover sheet feeding member having a cover sheet loading section for loading a cover sheet, for feeding the cover sheet stacked on the cover sheet loading section to the stacking member; a stapling member for stapling the cover sheet and the recording sheets stacked on the stacking member; and a folding member for folding the cover sheet and the recording sheets into two. The cover sheet feeding member, the stacking member and the folding member are substantially vertically arranged in the order from an upper portion to a lower portion of the sheet finisher.

A sheet finisher includes: a sheet stacking section on which sheets are stacked; a pair of folding rollers for pressing and conveying the sheets; a roller driving device for driving the pair of folding rollers; a protruding member which is protruded toward a nipping position of the pair of folding rollers to fold the sheets stacked on the sheet stacking section in two; and a protruding member driving device for driving the protruding member to protrude toward the nipping position. When the protruding member driving device drives the protruding member toward the nipping position, the roller driving device is suspended to drive the pair of folding rollers to be conveyed.

An image-forming apparatus is provided which can conduct folding processing that is suitable for a process to form an image on a sheet. The image forming apparatus includes a first folding device and a second folding device both of which conduct folding processing while conveying a sheet, a controller to control both of the first folding device and the second folding device, and a selector to select a two-folding mode or a three-folding mode. The controller controls the first folding device so as to eject the sheet after folding the sheet double when the two-folding mode is selected by the selector, while the controller controls the first folding device so as to fold the sheet double, and then, further controls the second folding device so as to eject the sheet after further folding the sheet in three when the selector selects the three-folding mode.

There are provided bookbinding apparatuses that wrap a bundle of sheets with a cover and form back corners, and have a detecting unit for detecting a wave amount of a bundle of sheets. A type of such an apparatus includes a controller to control a time period to form back corners, based on a result of detection by the detecting unit. Another type of such an apparatus includes a controller to control a pressure applied to form back corners, based on a result of detection by the detecting unit. Still another type of such an apparatus includes a controller to control a time period and pressure applied to form back corners, based on a result of detection by the detecting unit.

The invention concerns a hole-punching processor that forms punched-holes, for binding sheets into a file, on the sheets, which are ejected after images are formed on them from an image forming apparatus such as, for example, a copying machine, a printer, a facsimile machine or a compound machine thereof. The hole-punching processor forms a punched-hole on a sheet residing in a conveying path for conveying the sheet through the hole-punching processor. The hole-punching processor includes a hole-punching device being movable in a direction perpendicular to a conveyance direction of the sheet and a sheet-edge detector to detect a side-edge of the sheet in a direction parallel to the conveyance direction of the sheet. The hole-punching device moves with the sheet-edge detector to a center of the sheet, based on positional information of the side-edge detected by the sheet-edge detector, to punch a hole in the sheet.
