Provided is a stapler device installed to staple a bundle of papers processed and discharged from an image forming apparatus or a post-processing apparatus. The stapler device includes a stapler, and a moving unit installed to allow the stapler to reciprocate in a direction intersecting with a discharge direction of the bundle of papers. The moving unit may rotate the stapler outwardly such that a bundle of papers inserted from the outside in addition to the discharged bundle of papers is stapled in at least one end position of a range of the reciprocating movement.

A sheet processing apparatus includes a conveying portion, a stack portion on which sheets are stacked, a first binding portion moving in a crossing direction crossing a conveying direction, a first regulating portion regulating a position of a sheet bundle stacked on the stack portion in the crossing direction, a first rack moving in the crossing direction with the first regulating portion, a first pinion forming a rack-pinion mechanism with the first rack, a second regulating portion regulating a position of a sheet bundle stacked on the stack portion in the crossing direction, a second rack moving in the crossing direction with the second regulating portion, a second pinion forming another rack-pinion mechanism with the second rack, a third regulating portion regulating a position of a sheet bundle stacked on the stack portion, and a second binding portion which binds a corner portion of a sheet bundle without a staple.

A stapler includes a staple cartridge in which a staple is stored, a storage unit to which the staple cartridge is attached to be detachable, a staple ejecting unit which ejects out the staple to penetrate a paper sheet, a cutting unit which cuts a staple leg of the staple penetrating the paper sheet, a binding unit which binds the paper sheet by bending the staple leg of the staple penetrating the paper sheet, a cut staple storage unit which stores a cut staple that is cut by the cutting unit, and a discharge unit through which the cutting unit and the cut staple storage unit communicate with each other to guide the cut staple to the cut staple storage unit. The cut staple storage unit is attachable to and detachable from the stapler.

In construction of pallets, stringers are conveyed on a conveyor in a conveying direction to a pneumatic stop assembly including a pawl. The pawl is moveably mounted relative to the conveyor by a parallelogram linkage and moveable by a pneumatic actuator between first and second heights relative to the conveyor. While the pawl is at its first height, a lower board in a hopper is pushed from a shelf by a pusher onto the stringers on the conveyor. While pushed, the ends of the board slide along and between first and second slide rails on opposite sides of the conveyor. The board on the stringers is sandwiched between the pusher and the pawl at the first height while fastened together by a nail gun. After being fastened together, the pawl is moved to its second height which does not interfere with the fastened board and stringers conveyed by the conveyor.

A sheet processing apparatus includes a conveying portion, a stack portion on which sheets are stacked, a first binding portion moving in a crossing direction crossing a conveying direction, a first regulating portion regulating a position of a sheet bundle stacked on the stack portion in the crossing direction, a first rack moving in the crossing direction with the first regulating portion, a first pinion forming a rack-pinion mechanism with the first rack, a second regulating portion regulating a position of a sheet bundle stacked on the stack portion in the crossing direction, a second rack moving in the crossing direction with the second regulating portion, a second pinion forming another rack-pinion mechanism with the second rack, a third regulating portion regulating a position of a sheet bundle stacked on the stack portion, and a second binding portion which binds a corner portion of a sheet bundle without a staple.

A nail plater apparatus includes at least one nail plate magazine configured to hold a plurality of nail plates, and at least one nail plate extractor assembly associated with the at least one nail plate magazine and configured to position at least one nail plate therefrom to at least one nail plate pressing area. A board feeder is configured to position a board to a board receiving area. At least one nail plate presser assembly is adjacent the board receiving area and aligned with the at least one nail plate pressing area and configured to press the at least one nail plate into the board.

A sheet processing apparatus includes a conveying portion, a conveying path, a discharge port, a stacking portion, a manual setting portion, a binding device which binds a sheet bundle formed by the stacking portion and a sheet bundle set at the manual setting portion by a staple, a first regulating portion which regulates a position of the sheet bundle at a rear side of the apparatus in a width direction, and a second regulating portion which regulates a position of the sheet bundle in the conveying direction. The binding device is formed to be movable back and forth to a front side and the rear side of the apparatus. When a staple is replenished to the binding device, the binding device is positioned at the third position so that a cartridge of the staple is loaded into the binding device from the front side of the apparatus.

A sheet processing apparatus includes a conveying portion, a stack portion which stacks sheets, a first regulating portion which regulates a position of a sheet bundle in a crossing direction crossing to a conveying direction, a second regulating portion which regulates a position of a sheet bundle in the conveying direction, a first binding portion which moves from a first side to a second side and binds a corner portion of a sheet bundle by a staple, a second binding portion which binds a corner portion of a sheet bundle without a staple. The second binding portion includes a first face having a plurality of projections and a second face having a plurality of concave grooves matching the plurality of projections. A sheet bundle is bound by pressing the first face and the second face.

A fastening system includes a carriage moveably mounted to a frame between first and second positions extensive with and beyond a fixture. The fixture is horizontally movably mounted in the frame to receive components to be fastened of differing sizes, with slide bars vertically moveably mounted relative to the fixture and simultaneously horizontally movable with the fixture. Adjustable spacers, in the form of a body having different extents or telescopic pillars, are positioned in the frame to abut with the components received in the fixture. Wheels rotatably mounted to first and second platforms of the carriage are received in U-shaped channels of the frame, with the first and second platforms being moved by endless belts clamped thereto. Nail guns are movably mounted between vertical posts of the platforms and include a plunger which is biased against a drum carrying a belt of fasteners and include a flat board tangential to a roller having a V-shaped circumferential groove receiving the heads of nails. The slide bars are movable relative to the fixture by pivoting first and second links which are pivotably connected to each other.

A nail plater apparatus includes a board magazine configured to hold stacked boards, and a pair of spaced apart nail plate magazines, with each nail plate magazine configured to hold stacked nail plates. The nail plater apparatus includes a pair of spaced apart nail plate extractor assemblies, with each nail plate extractor assembly associated with a respective nail plate magazine and configured to position a nail plate therefrom to a respective nail plate pressing area. A board feeder is configured to position a board from the board magazine to a board receiving area, with ends of the board being aligned with the nail plates positioned in the respective nail plate pressing areas. A pair of spaced apart nail plate presser assemblies overlie ends of the board receiving area and is aligned with the respective nail plate pressing areas to press the nail plates into the ends of the board.
