Abstract
A paper cutting apparatus comprises a cutting unit to cut paper, a moving unit to move the cutting unit in a direction intersecting the conveyance direction of the paper, and a motor to drive the moving unit. The paper cutting apparatus also includes a detection unit to detect the current value of the motor and a determination unit to determine the state of the current value while the cutting unit that has begun moving from a specific position toward a target stop position is moving from a downstream end of the paper to a predetermined target stop position in the movement direction of the cutting unit. A control unit is configured to stop the drive of the motor on the basis of the determination result of the determination unit.
Claims9
A paper cutting apparatus, comprising:
- a cutting unit configured to cut paper;
- a moving unit configured to move the cutting unit from a moving start position to a stop position in a cutting direction intersecting the conveyance direction of the paper;
- a motor configured to drive the moving unit;
- a detection unit configured to detect a current value of the motor;
- an obtaining unit configured to obtain a paper cutting time required for the cutting unit to pass through the paper in the cutting direction from the moving start position to a distal end of the paper, and a moving time required for the cutting unit to move from the start position to the stop position;
- and
- a control unit configured to stop, before the moving time has elapsed, the drive of the motor on the basis of the current value,
- wherein the control unit does not execute determination for determining whether to stop the drive of the motor based on the current value, before the paper cutting time has elapsed following the start of movement of the cutting unit from the moving start position to the stop position, and
- wherein the control unit begins the determination after the paper cutting time has elapsed following the start of movement of the cutting unit from the moving start position to the stop position.
