Abstract
A sheet feeding apparatus, including: a stacking unit; a feed unit having a contact portion to be brought into contact with a sheet stacked on the stacking unit and a noncontact portion kept out of contact with the sheet, the feed unit being configured to feed the sheet in a contact state in which the contact portion is in contact with the sheet, and then turn into a noncontact state in which the noncontact portion faces the sheet so as to be kept out of contact with the sheet; a conveyance unit arranged downstream of the feed unit; and a drive unit configured to drive the conveyance unit at a first speed in the contact state and to drive the conveyance unit at a second speed higher than the first speed in the noncontact state.
Claims7
A sheet feeding apparatus, comprising:
- a stacking unit on which a sheet is to be stacked;
- a feed unit comprising:
- a contact portion to be brought into contact with the sheet stacked on the stacking unit;
- and
- a noncontact portion kept out of contact with the sheet,
- the feed unit being configured to feed the sheet in a contact state in which the contact portion is in contact with the sheet, and then turn into a noncontact state in which the noncontact portion faces the sheet so as to be kept out of contact with the sheet;
- a conveyance unit arranged downstream of the feed unit in a sheet feed direction and configured to convey the sheet fed by the feed unit;
- and
- a drive unit configured to drive the conveyance unit at a first conveying speed when the feed unit is in the contact state, and to drive the conveyance unit at a second conveying speed which is higher than the first conveying speed when the feed unit is in the noncontact state.
An image forming apparatus, comprising:
- a sheet feeding apparatus;
- and
- an image forming portion configured to form an image on a sheet fed by the sheet feeding apparatus,
- the sheet feeding apparatus comprising:
- a stacking unit on which a sheet is to be stacked;
- a feed unit comprising:
- a contact portion to be brought into contact with the sheet stacked on the stacking unit;
- and
- a noncontact portion kept out of contact with the sheet,
- the feed unit being configured to feed the sheet in a contact state in which the contact portion is in contact with the sheet, and then turn into a noncontact state in which the noncontact portion faces the sheet so as to be kept out of contact with the sheet;
- a conveyance unit arranged downstream of the feed unit in a sheet feed direction and configured to convey the sheet fed by the feed unit;
- and
- a drive unit configured to drive the conveyance unit at a first conveying speed when the feed unit is in the contact state, and to drive the conveyance unit at a second conveying speed which is higher than the first conveying speed when the feed unit is in the noncontact state.
