Abstract
A sheet feeding apparatus includes a stacking portion having a stacking surface on which sheets are stacked, a feeding portion configured to feed the sheets stacked on the stacking surface, and an abutment member having a contact surface configured to contact edges of the sheets stacked on the stacking surface and extending along a stacking direction of the sheets. The abutment member moves with a constant contact angle between the contact surface and the edges of the sheets in a cross section parallel with the stacking direction in a case where the contact surface is pushed by the sheets inserted toward the feeding portion in an insertion direction. In addition, a detection portion is configured to output a detection signal in accordance with a position of the abutment member.
