1. A feeding apparatus comprising
a roll supporter configured to rotatably support a roll sheet which is a sheet wound into a roll form;
a drive unit including a motor as a driving source and configured to rotate the roll sheet supported by the roll supporter in a first rotation direction for feeding the sheet from the roll sheet into a conveyance path and a second rotation direction reverse to the first rotation direction;
an abutment body provided so as to be capable of abutting against an outer peripheral surface of the roll sheet at a first position; and
a roller provided so as to be displaceable to an abutment position where the roller abuts against the outer peripheral surface of the roll sheet at a second position separated apart from the first position in the first rotation direction, and a retreat position where the roller does not abut against the outer peripheral surface,
wherein the drive unit rotates the roll sheet in the first rotation direction to introduce, into the conveyance path, a leading edge of the sheet having passed between the first position and the second position, and
the roller at the second position does not rotate with the roll sheet when the roll sheet is rotated in the first rotation direction, and rotates with the roll sheet when the roll sheet is rotated in the second rotation direction.
