Abstract
A sheet processing apparatus includes a saddle unit on which a mountain-folded sheet folded along a folding line is accumulated so as to straddle the saddle unit, a staple inserting section disposed above the saddle unit, and a staple receiving section accommodated in the saddle unit. The staple inserting section includes an inserting unit which inserts a staple into the folding lines of the sheets, and holding members disposed on both sides of the inserting unit in a direction parallel to the folding lines of the sheets. The staple receiving section includes a staple receiving unit which receives and bends the tips of the staple inserted by the inserting unit, and supporting members disposed on both sides of the staple receiving unit at positions opposite to the holding members.
Claims7
A sheet processing apparatus comprising:
- a saddle unit on which a mountain-folded sheet folded along a folding line at a middle portion is accumulated so as to straddle the saddle unit;
- a staple inserting section disposed above the saddle unit;
- a staple receiving section accommodated in the saddle unit;
- and
- a control section which controls the staple inserting section,
- wherein the staple inserting section comprises:
- an inserting unit which inserts a staple into the folding lines of sheets accumulated on the saddle unit;
- holding members disposed on both sides of the inserting unit in a direction parallel to the folding lines of the sheets accumulated on the saddle unit;
- and
- a drive unit which drives the holding members in a vertical direction,
- wherein the staple receiving section comprises:
- a staple receiving unit which receives and bends tips of the staple inserted by the inserting unit;
- and
- supporting members which are at least partly contained in containers disposed on both sides of the staple receiving unit at positions opposite to the holding members, respectively, top surfaces of the containers being adjacent to a top surface of the staple receiving unit,
- wherein the control section controls the drive unit so that the sheets are held between the holding members and the supporting members during driving of the staple into the folding lines of the sheets accumulated on the saddle unit by the inserting unit,
- wherein the supporting members are in a first position in which the supporting members are prominent from the top surfaces of the containers while the holding members are separated from the supporting members, and
- wherein the supporting members retract downward in response to a pressing force of the holding members to be in a second position in which a distance between top ends of the supporting members and the top surfaces of the containers is smaller than that in the first position, wherein the second position is a position such that the sheets are held between the holding members and the supporting members in the second position in a state that both sides of the folding line of one of the sheets contact the top surfaces of the containers and such that a ridge of the sheets is flattened and the sheets spread in a direction perpendicular to the ridge.
