Abstract
A sheet conveying device includes a tray, an elevating mechanism, a conveyance roller, and a resistance member. The tray stacks a plurality of sheets. The elevating mechanism lifts and lowers the tray in the stacking direction of a plurality of sheets. The conveyance roller conveys the plurality of sheets in the conveyance direction from the upper side in the stacking direction. The resistance member comes into contact with the leading ends of the plurality of sheets in the conveyance direction. The resistance member imparts a sliding resistance larger than that of the sheet stacking surface of the tray to the leading ends of the plurality of sheets that are lifted and lowered by the elevating mechanism.
Claims20
A sheet conveying device, comprising:
- a tray configured to accommodate a stack of a plurality of sheets;
- an elevating mechanism configured to lift and lower the tray in a stacking direction of the plurality of sheets;
- a conveyance roller configured to convey one sheet at a time from the plurality of sheets in the conveyance direction from the upper side in the stacking direction;
- a resistance member in contact with a leading end of the plurality of sheets in the conveyance direction and configured to impart a sliding resistance larger than a sliding resistance of a sheet stacking surface of the tray to the leading ends of the plurality of sheets that are lifted and lowered by the elevating mechanism;
- and
- an actuator configured to rotate when pushed by a leading end of the sheet, wherein
- the resistance member arranged on both sides of a conveyance center line in the sheet transfer device, and the actuator located between the resistance member arranged on both sides of the conveyance center line.
An image processing apparatus, comprising:
- an image forming device;
- and
- a sheet conveying device comprising:
- a tray configured to accommodate a stack of a plurality of sheets;
- an elevating mechanism configured to lift and lower the tray in a stacking direction of the plurality of sheets;
- a conveyance roller configured to convey one sheet at a time from the plurality of sheets in the conveyance direction from the upper side in the stacking direction;
- a resistance member in contact with a leading end of the plurality of sheets in the conveyance direction and configured to impart a sliding resistance larger than a sliding resistance of a sheet stacking surface of the tray to the leading ends of the plurality of sheets that are lifted and lowered by the elevating mechanism;
- and
- an actuator configured to rotate when pushed by a leading end of the sheet, wherein
- the resistance member arranged on both sides of a conveyance center line in the sheet transfer device, and
- the actuator located between the resistance member arranged on both sides of the conveyance center line.
A sheet conveying method, comprising:
- lifting and lowering a tray configured to accommodate a stack of a plurality of sheets in a stacking direction of the plurality of sheets using an elevating mechanism;
- conveying one sheet at a time from the plurality of sheets in the conveyance direction from the upper side in the stacking direction;
- contacting a resistance member with a leading end of the plurality of sheets in the conveyance direction and imparting a sliding resistance larger than a sliding resistance of a sheet stacking surface of the tray to the leading ends of the plurality of sheets that are lifted and lowered by the elevating mechanism;
- and
- rotating an actuator when pushed by a leading end of the sheet, wherein
- the resistance member arranged on both sides of a conveyance center line in the sheet transfer device, and
- the actuator located between the resistance member arranged on both sides of the conveyance center line.
