1. A sheet feeding apparatus comprising:
a supporting unit configured to support a sheet;
a sheet feeding unit configured to feed the sheet supported by the supporting unit in a feeding direction;
a separation unit configured to separate sheets fed by the sheet feeding unit one by one;
a first moving member disposed on one side of the sheet feeding unit in a width direction orthogonal to the feeding direction and configured to move by being pushed by the sheet supported by the supporting unit;
a second moving member disposed on the other side of the sheet feeding unit in the width direction and configured to move by being pushed by the sheet supported in the supporting unit;
a first sensor configured to detect the sheet based on a position of the first moving member;
a second sensor configured to detect the sheet at a position downstream of the separation unit in the feeding direction;
a third sensor configured to detect the sheet based on the position of the second moving member; and
a control unit configured to determine whether or not to allow the sheet to be fed by the sheet feeding unit based on the first sensor and the third sensor, and to control feeding timing at which the sheet feeding unit starts to feed the sheet based on detection results of the first sensor and the second sensor,
wherein the control unit is configured to allow the sheet to be fed by the sheet feeding unit in a case where both the first sensor and the third sensor detect the sheet, and not allow the sheet to be fed by the sheet feeding unit in a case where at least one of the first sensor or the third sensor does not detect the sheet.
