Abstract
In a case where an edge portion of a sheet is positioned within a detection range of a single sensor chip in a state where a reference position of the sheet is moved to a first target value, a control unit is configured to move the reference position of the sheet toward the first target value. In a case where an edge portion of a sheet is not positioned within a detection range of a single sensor chip in a state where a reference position of the sheet is moved to the first target value, the control unit is configured to move the reference position of the sheet toward a second target position offset from the first target. The second target position is a position where the edge portion of the sheet is positioned within the detection range of a single sensor chip.
Claims16
A sheet conveyance apparatus comprising:
- a moving unit including a roller configured to convey a sheet, the moving unit being configured to move a position of the sheet in a width direction orthogonal to a conveyance direction;
- a width position detection unit including a plurality of sensor chips aligned in the width direction, each sensor chip including a plurality of light receiving elements, the width position detection unit being configured to detect a position of an edge portion of the sheet in the width direction;
- and
- a control unit,
- wherein, in a case where a side edge of a sheet is positioned within a detection range of a single sensor chip in a state where a reference position of the sheet is moved to a first target position of a sheet conveyance path in the width direction, the control unit is configured to move the reference position of the sheet toward the first target position by the moving unit according to the detection result of the width position detection unit,
- wherein, in a case where a side edge of a sheet is not positioned within a detection range of a single sensor chip in a state where a reference position of the sheet is moved to the first target position, the control unit is configured to move the reference position of the sheet toward a second target position offset from the first target position by the moving unit according to the detection result of the width position detection unit, and
- wherein the second target position is a position where the edge portion of the sheet is positioned within the detection range of a single sensor chip.
