A recording material processing apparatus includes a processing tray, a detecting unit, a stapling unit, an instructing unit, a control unit, a switching unit, and a notifying unit. The detecting unit detects recording material placed in the processing tray. The stapling unit executes a stapling process for the recording material placed in the processing tray. The instructing unit outputs a stapling process execution instruction. Upon receipt of the execution instruction in a state in which the detecting unit has detected a recording material inserted in the processing tray from an outside of a main body of a main body apparatus, the control unit cause the stapling process to be executed. The switching unit switches a position of the stapling unit among a plurality of positions. The notifying unit provides notification of a placement position of the recording material in the processing tray corresponding to each of the plurality of positions.

The aligning device receives a sheet conveyed in a sheet conveyance direction in a stackable manner and aligns a position of the sheet in the sheet conveyance direction. The moving mechanism moves the sheet aligned by the aligning device in the sheet conveyance direction together with the aligning device. The controller selectively executes a first mode in which first post-processing is performed on the sheet and then second post-processing is performed on the sheet and a second mode in which the second post-processing is performed on the sheet without performing the first post-processing on the sheet. The controller, in response to a selection of the first mode or the second mode, causes the moving mechanism to adjust a position of the aligning device in the sheet conveyance direction before the aligning device receives the sheet as a target of the first post-processing or the second post-processing, respectively.

The present apparatus is provided with a placement tray (processing tray) to place sheets to undergo binding processing, and a bind unit that is able to shift along an end edge of sheets on the placement tray and that binds a plurality of sheets as a single bunch, where in the bind unit, a needle bind unit for performing binding processing on a bunch of sheets with a needle and a needleless bind unit for performing binding processing without a needle are provided together in a shift direction of the bind unit, and a length of the needleless bind unit is configured to be shorter than a length of the needle bind unit in the shift direction of the bind unit. By this means, provided is the apparatus capable of miniaturizing the entire apparatus, with the needle bind unit and needleless bind unit provided together.

A stapling device of a paper finishing device of one embodiment of the present disclosure includes a stapler including an entrance into which one side of paper is inserted, a moving part including a stapler moving bracket on which the stapler is seated and a moving roller installed on the stapler moving bracket, a driving part which moves the stapler moving bracket, a base frame on which the stapler moving bracket and the driving part are installed, and which includes a horizontal guide surface extending along the one side of the paper, a first corner stapling guide surface spaced apart from the horizontal guide surface, and a first inclined guide surface which diagonally connects the horizontal guide surface and the first corner stapling guide surface, and a position guide part which is installed on the base frame and includes a second corner stapling guide surface and a second inclined guide surface which diagonally connects the horizontal guide surface and the second corner stapling guide surface and is inclined to be opposite to the first inclined guide surface.

A sheet processing device includes a first conveyance passage, a first conveyor, a second conveyor, a folder, a second conveyance passage, and circuitry. The circuitry is configured to (1) cause the first conveyor and the second conveyor to convey the sheet nipping the sheet to warp the sheet between the first conveyor and the second conveyor, (2) guide the warped sheet to form a first fold on the sheet by the folder and circulate the sheet to the first conveyance passage, (3) cause the first conveyor and the second conveyor to convey the sheet while nipping the sheet again to warp the sheet between the first conveyor and the second conveyor, (4) guide the warped sheet to form a second fold on the sheet by the folder, and (5) cause the second conveyor to convey the sheet with the first fold and the second fold.

A sheet processing device includes: an adhesive-binding unit that applies an adhesive onto sheets stored in a stacker section one by one and adhesive-binds the sheets; a staple-binding unit that staple-binds sheets accumulated in the stacker section by means of staples; and a folding mechanism section having a folding roller that folds the adhesive-bound or staple-bound sheet bundle in two at a binding position of the adhesive-binding unit or staple-binding unit and a folding blade that pushes the bound sheet bundle into the folding roller. A folding speed of the folding mechanism section for the sheet bundle bound by the adhesive-binding unit is lower than a folding speed for the sheet bundle bound by the staple-binding unit; thereby, productivity of the folding processing is improved and occurrence of the peeling-off or break during the folding processing is reduced.

A sheet post-processing apparatus includes a first sensor, a second sensor and a controller. The first sensor detects whether or not a staple for performing a binding processing is prepared in a stapler. The second sensor detects that an amount of the staples held by the stapler has become not more than a prescribed amount. The controller judges whether or not to transfer an operation mode of the sheet post-processing apparatus to a first operation mode to perform the binding processing by the stapler to the sheets to be manually fed, based on a detection result of the second sensor, and judges whether or not to perform the binding processing by the stapler, based on a detection result of the first sensor, after having transferred the operation mode to the first operation mode.

According to one embodiment, a sheet post-processing apparatus includes: a standby unit configured to put a sheet on standby, the standby unit including a tray member on which the sheet is placed; a corrugation forming unit configured to form a corrugation in a direction orthogonal to a conveying direction on the sheet in the standby unit, the corrugation forming unit integrally provided with the tray member; and a processing unit disposed below the standby unit and configured to process the sheet supplied from the standby unit, wherein the corrugation forming unit includes: a projecting roller projecting upward from a conveyance reference plane in the standby unit; and a housing unit configured as a part of the tray member to house the projecting roller below the conveyance reference plane.

This compact binding device is such that binding operations can be carried out when the main body of the device is held. The binding device (1A) is provided with a cassette storage unit (60A) in which a cassette (8) can be detachably attached, said cassette housing an elongate tape (5) which has a piece (2) adhered thereto and is wound into a roll. The cassette housing unit (60A) is provided at the bottom of the device main body (110A), which comprises a base unit (11A) and a handle unit (12), and the cassette (8) does not protrude rearwards from the handle unit (12) and the base unit (11A).

A sheet folding apparatus includes a retract path that is positioned on the upstream side of a stacker section for collecting sheets and that branches off from a transport path to enable a sheet carried in the stacker section to be transported in a direction opposite to a carry-in direction, an adhesion unit that is positioned in a junction position of the transport path and the retract path to bond sheets by applying an adhesive, a staple binding unit that binds sheets collected in the stacker section with a staple, and a folding processing section that folds sheets bound with the unit. The retract path is a path for retracting an application position of the preceding sheet with the adhesive applied, in carrying a next sheet in the stacker section, and the staple binding unit is disposed in the stacker section between the adhesion unit and the folding processing section.
