Abstract
A feeding apparatus feeds sheets to an apparatus serving as a feeding destination. A sheet storage unit stores the sheets and is able to be pulled out from the feeding apparatus. A stacking unit stacks the sheets. A detection unit detects a connected state and a separated state. A control unit places the uppermost sheet stacked on the stacking unit at a predetermined height when the detection unit detects the connected state. A control unit lowers the stacking unit so as to move the uppermost sheet at the predetermined height on the stacking unit to a position lower than the predetermined height in accordance with detection of a change from the connected state to the separated state by the detection unit.
Claims10
A feeding apparatus that feeds sheets to an apparatus serving as a feeding destination, the feeding apparatus comprising:
- a sheet storage unit configured to store the sheets, the sheet storage unit being movable between a first position where the sheet storage unit is accommodated at least partially within the feeding apparatus and a second position where the sheet storage unit is pulled out from the feeding apparatus, the sheet storage unit including a stacking unit which is liftably and lowerably arranged inside the sheet storage unit and on which the sheets are stacked;
- a conveying unit including a roller pair configured to convey a sheet, of the sheets stacked on the stacking unit, which is fed from a predetermined height, wherein the conveying unit is provided within the feeding apparatus in a state that the sheet storage unit is at the first position and in a state that the sheet storage unit is at the second position;
- a connection/separation detection unit configured to detect a connected state in which the feeding apparatus is connected to the apparatus serving as the feeding destination so as to allow a sheet to be fed and a separated state in which the feeding apparatus is separated from the apparatus serving as the feeding destination;
- a sheet detection unit configured to detect presence and absence of a sheet on the stacking unit;
- and
- a control unit configured to:
- move the stacking unit to a position where the sheet on the stacking unit is at the predetermined height in response to the sheet detection unit detecting presence of a sheet when the connection/separation detection unit detects that the feeding apparatus changes from the separated state to the connected state in a state in which the sheet storage unit is in the first position, and
- move the stacking unit to a position where the sheet on the stacking unit is lower than the predetermined height and higher than a lowest limit position in a movable range of the stacking unit in response to the sheet detection unit detecting presence of a sheet when the connection/separation detection unit detects that the feeding apparatus changes from the connected state to the separated state in a state in which the sheet storage unit is in the first position.
