Recording apparatus and paper feeding method

A recording apparatus comprising:

• a support mechanism configured to rotatably support a roll around which a sheet is to be wound;
• a driving mechanism configured to rotate the roll supported by the support mechanism in a first direction to feed the sheet from the roll, and rotate the roll in a second direction that is opposite to the first direction to rewind the sheet onto the roll;
• a conveying passage configured to guide the sheet fed from the roll supported by the support mechanism in a feeding direction;
• a conveyer disposed on a downstream side of the conveying passage in the feeding direction to convey the sheet;
• a recording head configured to record an image on the sheet conveyed by the conveyer;
• and
• a detector for detecting a position of a leading end of the roll,
• wherein the conveying passage has a first position upstream of the conveyer in the feeding direction and a second position upstream of the first position in the feeding direction,
• wherein the driving mechanism is configured to perform, before the sheet reaches the conveyer, a reciprocating operation in which the driving mechanism rotates the roll in the second direction in response to a to the leading end of the sheet reaching the first position and rotates the roll in the first direction in response to the leading end which reached the first position reaching the second position,
• wherein the detector is a plurality of optical sensors configured to project light and determine whether the sheet is at a corresponding position based on a presence or absence of reflected light, and
• wherein the plurality of optical sensors includes a first sensor located at a position corresponding to the first position and a second sensor located at a position corresponding to the second position.
