Abstract: A recording apparatus having a support portion that supports a roll having a wound sheet, a drive portion, a conveying passage, a conveyer, and a recording portion. The drive portion rotates the supported roll in a first direction to feed the sheet from the roll, and rotates the roll in a second direction to rewind the sheet onto the roll. The conveying passage guides the sheet fed from the roll in a feeding direction and has first and second positions upstream of the conveyer in the feeding direction. The drive portion performs, before the sheet reaches the conveyer, a reciprocating operation in which the drive portion rotates the roll in the second direction in response to a 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.
