There is disclosed a sheet post-processing device which can staple a corner of a sheet bunch conveyed from an image forming device and makes a transverse width of a housing smaller or compact. By disposing a stapler in one end on a sheet processing tray inside a sheet conveying port, the transverse width of the housing is made smaller. For this purpose, the sheet post-processing stores sheets conveyed from the image forming device, matches the sheet bunch stored staples the matched sheet bunch and transfers the matched sheet bunch toward the other end of the sheet bunch and subsequently transfers the stapled sheet bunch toward one end of the sheet bunch.

Sheets post processing device including stapler for variable widths

A method and apparatus for resetting a sheet processing device is disclosed in which even if a trouble occurs, a sheet processing can be continued after resetting without wasting the previous processing. In a sheet processing device in which a set of sheets conveyed from an image forming device is discharged to a discharge tray after a predetermined processing process, the processing process is finely divided into plural function units and the function units are individually reset. In a memory device, a status flag indicating the condition of each module unit is assigned to each unit. The presence of a partially performed operation is confirmed by the status flag, and only the function unit having partially performed operation is reset to its initial condition.

A sheet handling device for accommodating, aligning and storing sheets fed from an image forming apparatus such as a copying machine is provided with front-side and rear-side aligning members for pressing the sheets stacked on a first storage means between the aligning members to stably and exactly align the stacked sheets. The front side aligning member is movable vertically or rotatable to open a sheet transferring passage so as to enable a sheet aligning mechanism in the sheet handling device to be operated in a small space, and thus, made compact. While transferring the aligned sheets from the first storage means to a second storage means, the aligned sheets are stably held by the front-side aligning member being in soft contact with the upper surface of the sheets being transferred.

There is disclosed a sheet accumulation processing device in which sheets with images formed thereon are processed as a bunch before the sheet bunch is efficiently sorted and discharged to any one of plural discharge trays. The device comprises a load-carrying device for piling plural sheets; a sheet bunch discharging means for discharging a sheet bunch piled on the load-carrying device via a discharge port; plural discharge trays for storing the sheet bunch discharged by the sheet bunch discharging device; a discharge tray moving device for moving the discharge trays; a tray position detecting device for detecting positions of the discharge trays relative to the discharge port; a sheet presence detecting device for detecting presence of the sheets on the discharge trays; and a control device for selecting the discharge tray to which the sheet bunch is to be discharged based on detection results of the tray position detecting device and the sheet presence detecting device and moving the selected discharge tray by the discharge tray moving device. The control device selects a discharge tray which stores no sheet and is positioned closest to the discharge port as the discharge tray of the sheet bunch, and moves the selected tray to the discharge port, thereby minimizing the operation of moving the tray and shortening a setup time.

Sheet accumulation processing device

A sheet handling apparatus receives on a handling tray a plurality of sheets discharged from an image recording apparatus such as a printer, a copier or the like in a first direction, thereby forming a sheet stack of a series of sheets on the handling tray, and transfers the sheet stack onto an accumulation tray which is disposed with respect to the handling tray in a second direction which intersects the first direction. A first gripper grips the sheet stack on the handling tray and transfers it toward the accumulation tray in the second direction, and a second gripper which grips the sheet stack at an edge portion on the image recording apparatus side receives the sheet stack from the first transfer means after the first transfer means transfers the sheet stack by a predetermined distance in the second direction and transfers the sheet stack in the second direction.

Sheet handling apparatus

A sheet handling apparatus receives a plurality of sheets discharged by a discharge roller pair from an image recording apparatus on a first support member disposed below the discharge roller pair to form a stack of the sheets on the first support member and carries out handling on the stack of sheets. A second support member is supported to be movable back and forth between a projecting position where it is projected over the first support member and is able to support a rear end portion of a sheet discharged by the discharge roller pair with a front end portion of the sheet supported by the first support member and a retracted position where it is retracted from the first support member. A controller controls movement of the second support member.
