  • Patent number: 10369829
    Abstract: A staple-less binding unit including a pair of upper and lower teeth binds a sheet bundle which is discharged to an intermediate processing tray by a sheet discharge portion and whose one edge abuts against a rear edge stopper. A control portion switches a binding mode of the staple-less binding unit that implements the binding process on the sheet bundle in a first binding mode of binding the sheet bundle without any staple such that the pair of upper and lower teeth bite across an edge of the sheet bundle and in a second binding mode of binding the sheet bundle without any staple such that the pair of upper and lower teeth do not bite across any edge of the sheet bundle.

The post-processing device includes: an alignment mechanism for applying an alignment process for arranging a current sheet bundle; an output mechanism for outputting the current sheet bundle; a prestacking mechanism; and a control unit. The control unit performs a control in such a manner that at least a part of operation of the alignment mechanism or of operation of the output mechanism is switched from a normal operation mode for operation at a normal operation speed to a high-speed operation mode for operation at an operation speed greater than the normal operation speed when a time to completely output the current sheet bundle is later than a time to completely perform prestacking the next sheet bundle.

  • Patent number: 9039002
    Abstract: A sheet post-processing apparatus which is capable of shortening time wasted until actual start of punching and enhancing productivity. A drive unit causes a moving member which has a cam and reciprocates. A punching member is driven by a movement of the cam of the moving member and punches a sheet when the moving member moves forth and moves back. A determination unit determines a type of the sheet. A control unit controls, when a sheet to be punched is to be subjected to a punching process, the drive unit such that the moving member starts moving before conveyance of the sheet to be punched stops, and controls, when the sheet to be punched is to be subjected to the punching process, the drive unit such that timing with which the moving member starts moving is changed based on the determination by the determination unit.

  • Patent number: 9010753
    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.

  • Patent number: 8998192
    Abstract: In the invention, for a first sheet, regardless of the sheet size (width), a lateral registration detector is moved in a direction towards an edge face of the sheet from a home position to detect the edge face of the sheet. With lateral deviation in the sheet position corrected, punching is performed by a puncher. For the second and subsequent sheets, the lateral registration detector is moved in advance to near the edge face of the sheet with reference to the detected position of the sheet edge of the first sheet, and the edge face is detected at a given timing. With lateral deviation in the sheet position corrected, punching is performed by the puncher.
