Abstract
A sheet conveyance apparatus includes a rotary member pair, a movement portion, a detection portion, an abutment member, an oblique conveyance portion, and a controller configured to, on a basis of a detection result of the detection portion, move the rotary member pair in a width direction by the movement portion such that a position, in the width direction, of the downstream end of the sheet is a set position in a state in which the rotary member pair is nipping the sheet and before the sheet reaches the oblique conveyance portion. The controller is configured to execute a correction mode of correcting the set position.
Claims9
A sheet conveyance apparatus comprising:
- a rotary member pair configured to nip and convey a sheet in a sheet conveyance direction;
- a movement portion configured to move the rotary member pair in a width direction orthogonal to the sheet conveyance direction in a state where the sheet is nipped by the rotary member pair;
- a detection portion configured to detect a position of a side-edge of the sheet;
- an abutment member disposed downstream of the rotary member pair in the sheet conveyance direction and configured to be positionally movable in the width direction, the abutment member including an abutment surface configured to extend along the sheet conveyance direction;
- an oblique conveyance portion disposed downstream of the rotary member pair in the sheet conveyance direction and configured to convey the sheet obliquely in a direction inclined with respect to the sheet conveyance direction such that the sheet approaches the abutment surface in the width direction;
- and
- a controller configured to, on a basis of a detection result of the detection portion, control the movement portion to move the rotary member pair in the width direction before the sheet reaches the oblique conveyance portion such that a position, of the side edge of the sheet in the width direction, is spaced from the abutment surface by a predetermined distance in the width direction,
- wherein the controller is configured to correct the detection portion such that, when a position of the abutment member is moved in the width direction, the movement portion moves the rotary member pair to move the sheet so as to be spaced from the abutment surface of the abutment member which has been moved in the width direction by the predetermined distance in the width direction.
