Abstract
A sheet feeding apparatus including: a sheet stacking unit on which a sheet is stacked; a feed member configured to abut against the sheet stacked on the sheet stacking unit to feed the sheet; a friction member disposed on the sheet stacking unit so as to be opposed to the feed member; a drive unit configured to drive the feed member; a detection unit configured to detect a load on the drive unit when the drive unit drives the feed member; and a control unit configured to control the drive unit, so that the control unit causes the drive unit to drive the feed member at a first speed and thereafter in a case where the load detected by the detection unit satisfies a predetermined condition, the control unit causes the drive unit to drive the feed member at a second speed higher than the first speed.
Claims13
A sheet feeding apparatus comprising:
- a sheet stacking unit on which a sheet is stacked;
- a feed member configured to abut against the sheet stacked on the sheet stacking unit to feed the sheet;
- a friction member disposed on the sheet stacking unit so as to be opposed to the feed member;
- a drive unit configured to drive the feed member;
- a detection unit configured to detect a load on the drive unit when the drive unit drives the feed member;
- and
- a control unit configured to control the drive unit, so that the control unit causes the drive unit to drive the feed member at a first speed and thereafter in a case where the load detected by the detection unit satisfies a predetermined condition, the control unit causes the drive unit to drive the feed member at a second speed higher than the first speed.
A sheet feeding apparatus comprising:
- a sheet stacking unit on which a sheet is stacked;
- a feed member configured to abut against the sheet stacked on the sheet stacking unit to feed the sheet;
- a conveyance unit disposed downstream of the feed member in a conveyance direction of the sheet by the feed member and configured to convey the sheet;
- a friction member disposed on the sheet stacking unit so as to be opposed to the feed member;
- a drive unit configured to drive the feed member;
- a detection unit configured to detect a load on the drive unit when the drive unit drives the feed member;
- and
- a control unit configured to control the drive unit, so that the control unit causes the drive unit to start to drive the feed member at a first drive force and thereafter in a case where the load detected by the detection unit satisfies a predetermined condition, the control unit sets a drive force given to the feed member by the drive unit to be smaller than the first drive force.
A sheet feeding apparatus comprising:
- a sheet stacking unit on which a sheet is stacked;
- a feed member configured to abut against the sheet stacked on the sheet stacking unit to feed the sheet;
- a friction member disposed on the sheet stacking unit so as to be opposed to the feed member;
- a drive unit configured to drive the feed member;
- a detection unit configured to detect a load on the drive unit when the drive unit drives the feed member;
- an adjustment unit configured to adjust an abutment pressure between the feed member and the sheet stacked on the sheet stacking unit;
- and
- a control unit configured to control the drive unit, so that the control unit causes the drive unit to start to drive the feed member in a state in which the feed member abuts against the sheet at a first abutment pressure and thereafter in a case where the load detected by the detection unit satisfies a predetermined condition, the control unit controls the adjustment unit so that the feed member is brought into a state in which the feed member abuts against the sheet at a second abutment pressure smaller than the first abutment pressure.
