摘要:
The object of the present invention is to provide a sheet processing apparatus for passing sheets between an upper jaw and a lower jaw of a binder that is fixed on a intermediate stacking portion and stapling the ends of the sheet, wherein binding processing is possible for a large number of sheets and the problems of paper jams due to inclining or poor alignment are solved and which has a small size, is low in cost and is highly reliable. In order to achieve the above object, a typical configuration of the sheet processing apparatus of the present invention comprises: a conveyance portion which conveys sheets; an intermediate stacking portion which temporarily stacks sheets conveyed from the conveyance portion; and a binder which performs a binding process for binding the sheets stacked in the intermediate stacking portion, and the binder is fixed at one side of the intermediate stacking portion and the sheet which is conveyed from the conveyance portion passes the opening of the binder and is stacked in the intermediate stacking portion; the conveyance portion comprises a plurality of drive rollers in the direction that intersects the conveyance direction; and the drive rollers other than the drive roller that is closest to the binder form conveyance roller pairs with driven rollers.

The detachment of a feed roller rotatably supported by a holding portion provided in the main body of an apparatus, and held detachably in the axial direction thereof is restricted by a locking device. The locking device is made movable to a lock position and a lock releasing position for permitting the detachment of the feed roller. Further, when the locking device is in the lock releasing position when a sheet stacking portion is mounted, the locking device is moved to the lock position by a position changeover device in operative association with the mounting operation of the sheet stacking portion.

A sheet processing apparatus, which is configured in a simple construction and at low cost, includes a first sheet stacking portion for temporarily stacking a sheet discharged thereon, an alignment member for aligning the sheet discharged on the first sheet stacking portion, a sheet processing member for performing a predetermined process on the sheet stacked on the first sheet stacking portion, and a second sheet stacking portion located substantially vertically below the first sheet stacking portion. The alignment member acts to cause the aligned sheet to drop to the second sheet stacking portion.

A sheet conveyed by a conveying member is pressed against a registration roller pair in a stop state, thereby forming a loop in a loop formation space between the conveying member and the registration roller pair. A lower member which forms the lower surface of the loop formation space has a shape with which the sheet conveyed by the conveying member moves toward the registration roller pair along an upper member which forms the upper surface of the loop formation space in forming the loop. When the lower member is pressed by the sheet conveyed by the registration roller pair while attenuating the loop, the lower member moves downward.
