Abstract:
A sheet feeding apparatus includes a sheet presence/absence detection sensor configured to detect presence or absence of a sheet on a stacking device, a sheet surface detection sensor configured to detect that a stacking tray is raised to enable a sheet to be fed, a separation cam, and a control unit. The control unit is configured to determine that the mounting state of a feeding holder to a holder support unit is defective when the sheet surface detection sensor detects that the sheet can be fed when the sheet presence/absence detection sensor detects absence of a sheet before sheet feeding processing by a pickup roller.

Claim (Index 14):
A sheet feeding apparatus for feeding a sheet, comprising:\n a stacking device onto which a sheet is stacked and which is movable; a feeding unit comprising a feeding member configured to contact the sheet on the stacking device to feed the sheet, the feeding unit being configured to hold the feeding member; a support device arranged above the stacking device and configured to removably support the feeding unit; a moving member configured to move by contacting a sheet on the stacking device; a detection device configured to switch between a light transmitting state and a light shielding state by movement of the moving member; and a switching device configured to switch a state of the detection device between the light transmitting state and the light shielding state in response to a state in which the feeding unit is mounted to the support device or not mounted to the support device.
