1. A sheet feeding apparatus comprising:
a sheet support configured to support a sheet;
a sheet feeder configured to contact an upper surface of the sheet supported on the sheet support and feed the sheet;
a feed position sensor configured to output a detection signal that changes according to whether the sheet feeder is at a predetermined feeding position;
a spring configured to urge the sheet feeder downward;
a conveyor configured to convey the sheet fed from the sheet feeder;
a first motor configured to drive the sheet feeder and the conveyor;
a second motor configured to rotate in a first direction and in a second direction opposite to the first direction;
a lift connected to the second motor and configured to lift the sheet feeder in a case where the second motor rotates in the second direction; and
a controller configured to control the first motor and the second motor,
wherein during a job of feeding a sheet from the sheet support, the controller is configured to start rotation of the second motor in the second direction after starting feeding of a final sheet in the job and before stopping the first motor,
wherein the lift is configured to lift and lower the sheet feeder to an upper position above the feeding position and a lower position below the feeding position, and
wherein in a case where the second motor rotates in the first direction, after the sheet feeder has moved from the upper position to the lower position, the lift allows the sheet feeder to be pressed by the sheet supported on the sheet support and moved from the lower position to the feeding position against an urging force of the spring.
