1. A sheet feeding apparatus, comprising:
a driving unit configured to rotate a roll in a first direction for feeding a sheet from the roll and in a second direction opposite to the first direction;
a lower guide configured to support the sheet of the roll from below;
a first contact unit supported by the lower guide and configured to contact the roll;
a second contact unit configured to be in contact with the roll at a contact position above the lower guide; and
a detection unit configured to detect a sheet end of the roll in a case where the sheet end of the roll rotated by the driving unit in the second direction passes through the contact position, and the sheet approaches,
wherein as an operation that automatically feeds the sheet from the roll, in a state in which the first contact unit contacts the roll, the driving unit rotates the roll in the second direction, the detecting unit detects the sheet end that rotates in the second direction, and then the driving unit rotates the roll in the first direction.
