Claims14
A sheet storage apparatus for storing a sheet conveyed by a sheet conveyance unit, comprising:
- a plurality of sheet storage units vertically stacked at a plurality of stages;
- a lower guide disposed in each of the plurality of sheet storage units and configured to guide a lower surface of the conveyed sheet;
- an upper guide disposed in each of the plurality of sheet storage units and configured to guide an upper surface of the conveyed sheet;
- a rotary member disposed in each of the plurality of sheet storage units and in one of the lower guide and the upper guide, and configured to be rotatable by contacting a sheet stored in a sheet storage unit from a home position around a rotational axis extending in a direction orthogonal to a sheet conveying direction;
- a sensor disposed in each of the plurality of sheet storage units and configured to output a signal according to a position of the rotary member;
- and
- a control unit configured to detect presence of a sheet in the sheet storage unit according to an output of the sensor,
- wherein at the home position, at least a part of the rotary member overlaps a rotational axis of a rotary member of an adjacent sheet storage unit in a vertical direction.
