Abstract
A cartridge detachable from a printer has a roll paper unit including roll paper, a roller, and flanges, and a separation member used to pull out the roll paper from the roll paper unit. Upon rotating the roll paper unit in a direction to feed out the roll paper, the roll paper is brought into contact with the separation member, thereby pulling out the roll paper from the roll paper unit and feeding out the roll paper to outside the cartridge.
