Abstract: 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.

Abstract: A hinge device which can be readjusted easily by bringing a rotating member into contact with a friction member. A first fixing member 10 fixed to a copying machine 1 and a second fixing member 11 fixed to an ADF 2 are connected to each other by means of a first shaft member 13 bearing them so as to be free to rotate; the member 10 has a rotating member 7 fixed to a second shaft member 16 arranged in parallel with the shaft member 13. The member 7 is put into contact with a friction member 15 arranged on the shaft member 13 to form a frictional portion. The member 15 is always in contact with the member 7 on its surface. A hole for bearing the shaft member 16 is an oblong hole 14, with its bottom surface which allows the shaft member 16 to take rocking motions for an arbitrary adjustment of a contact pressure to the member 7.

Abstract: There is disclosed a sheet distribution device in which when sheets are discharged to each distribution bin by a sheet moving means, reduced is a period of time required for shifting to the next sheet moving operation after one sheet moving operation is finished. The sheet distribution device receives image formed sheets 2 from an image forming device 1 and distributes and stores the sheets 2 into plural distribution bins 4. The sheet distribution device is provided with a post-processing means for post-processing the sheets 2 stored in the distribution bin 4, a sheet bunch pushing member 50 for moving the sheets 2 stored in the distribution bin 4 along the guide hole 28 in the distribution bin 4 to the post-processing means, and a guide rail 41 for elevating or lowering the sheet bunch pushing member 50. When the sheet bunch pushing member 50 is moved along the guide rail 41, the sheet bunch pushing member 50 can be moved in a direction in which the engagement with the guide hole 28 is released.

Abstract: There is disclosed a sheet distribution device in which by using a junction conveying means for conveying sheets from a main sorter unit to a slave sorter unit also as a first conveying portion of the sheet distribution device when sheet distribution devices are interconnected, the manufacture cost of the sheet distribution device is reduced. The interconnectable sheet distribution device is provided with a first conveying portion 5A for receiving an image formed sheet 2 from an image forming device 1 to convey the sheet into a body and a second conveying portion 5B for receiving the sheet 2 from the first conveying portion 5A to convey the sheet to each of plural distribution bins 4. At the time of interconnection, a third conveying portion 5D (junction conveying means) for conveying the sheet 2 from a main sorter unit S1 to a slave sorter unit S2 is used also as the first conveying portion 5A.

Abstract: There is disclosed a sheet distribution device in which by making various the modulus of elasticity of a stopper member and a sheet matching member, a stopper function at the time of discharging a sheet and a matching function at the time of matching the sheet are sufficiently fulfilled, respectively. The sheet discharge device is provided with a sheet position regulating member which abuts on a discharge tip end of a sheet 2 with an image formed thereon discharged from an image forming device 1 onto a distribution bin 4 to regulate a position of the sheet 2. The position regulating member is constituted of a stopper member 45 and a sheet matching member 40 which differ in modulus of elasticity from each other. At the time of discharging the sheet and at the time of matching the sheet, the stopper member 45 is moved relative to the sheet matching member 40 to advance or retreat in a sheet conveying direction.
