Abstract:
A sheet processing device includes a sheet processing unit that is moved to perform sheet processing on a sheet; a sheet-processing moving unit that moves the sheet processing unit; a drive-mode determining unit that determines a drive mode of the sheet-processing moving unit; and a drive control unit that drives the sheet-processing moving unit in accordance with the drive mode. The drive-mode determining unit determines the drive mode such that the sheet processing unit is moved at combination acceleration that is a combination of first acceleration and second acceleration with a shift of time that is determined based on the cycle of the natural vibration that occurs during acceleration of the sheet processing unit.
Abstract:
A sheet binding device binds a sheet bundle by causing a movable-crimping-member moving unit to move a movable crimping member thereby holding a sheet bundle between crimping members. The movable-crimping-member moving unit includes: a link mechanism that includes a first link member rotatably connected to the movable crimping member, a second link member rotatably connected to a fixed member fixed to a device body and connected to the first link member through a connecting part; a connecting member rotatably connected to the connecting part, and capable of moving between a first position causing the link mechanism to be extended and a second position causing the link mechanism to be more flexed than in the first position; and a connecting-member moving unit that includes a rotary member capable of rotating on a displaceable rotating shaft, and reciprocates the connecting member by rotation of the rotary member in one direction.
Abstract:
A sheet processing apparatus including a stacking tray that stacks sheets, a conveying member that conveys a sheet to the stacking tray and discharges the sheet bundle from the stacking tray, wherein the conveying member includes a conveying roller and a conveying belt stretched by a plurality of stretch rollers, and a sheet processor that performs predetermined processing to the sheet bundle. When the conveying member conveys the sheet to the stacking tray, a part of the conveying belt that is not wound on the stretch roller contacts the conveying roller by moving the conveying belt as such a nip for conveying the sheet is formed. When the conveying member discharges the sheet bundle from the stacking tray, a part of the conveying belt that is wound on the stretch roller contacts the conveying roller by moving the conveying belt so that a nip for conveying the sheet is formed.

Abstract:
An insertion system includes a folding device to perform either single-sheet folding to fold a single sheet at a time or batch folding to fold multiple sheets together at a time, an insertion device to insert into an envelope the sheet folded by the folding device, and a batch setting unit to designate either the single-sheet folding or the batch folding from a folding and insertion menu for multiple sheets at a time when the multiple sheets are processed by the folding device and the insertion device.
Abstract:
A sheet processing apparatus includes a stacking channel to stack multiple sheets into a sheet bundle, and a binding device to bind together the sheet bundle, the binding device including multiple clamping portions to clamp the sheet bundle to create multiple clamping marks on the sheet bundle. When the binding device binds a corner area of the sheet bundle, a longitudinal direction of each of the multiple clamping marks forms an angle within a range from 30 degrees to 60 degrees with a side of the corner area of the sheet bundle.
Abstract:
A sheet processing apparatus performs predetermined processing on a sheet or a sheet bundle. The sheet processing apparatus includes: a conveying unit that conveys a sheet along a conveying path; an aligning unit that, each time a sheet is conveyed by the conveying unit, aligns the sheet; a stacking unit that reverses a conveying direction of a sheet to convey the sheet backward to a branch path branched from the conveying path, and stacks the sheet in the branch path; and a binding unit that binds a sheet bundle aligned by the aligning unit, in the conveying path.
Abstract:
In an embodiment, a booklet conveying device includes: a pair of conveying units; a positioning unit; a pressing unit; and a conveying-force changing unit. The pair of conveying units convey a booklet made of a stack of folded sheets, and change a distance therebetween. The positioning unit positions the booklet by making a leading-end portion of the booklet abut thereto. The pressing unit presses the booklet positioned by the positioning unit onto one of the conveying units in order to fix. The conveying-force changing unit changes the conveying force exerted by the conveying units.
Abstract:
A bookbinding device receives a sheet on which an image is formed from an image forming apparatus. In the bookbinding device, a punching unit performs a punching process on a sheet; an aligning unit aligns a plurality of sheets on which holes are punched; and a ring binding unit mounts, in the holes of the sheets aligned by the aligning unit, a ring-shaped binding tool to create a booklet. A prohibiting unit, if a sheet received from the image forming apparatus is a punched sheet having a hole thereon, causes the punching unit not to perform the punching process on the punched sheet.
Abstract:
A punching processing unit punches holes in a paper bundle delivered from a preprocessing device. A bookbinding unit includes a cartridge for stocking a plurality of rings, and performs a ring binding by binding the paper bundle with the rings. A detecting unit detects an abnormality of a ring in the cartridge. A control unit exchanges a signal with the preprocessing unit each time when detection information obtained by the detecting unit changes. When any one of the rings is determined as abnormal and an execution of ring binding is set, the control unit inhibits the ring binding.
