Abstract
A roll sheet, in which a continuous sheet is wound in a roll form, is caused to rotate in a forward direction to supply the sheet to a printing unit. First and second sensors are arranged at positions facing an outer circumferential surface of the roll sheet and deviated in an axis line direction of the roll sheet. Outputs of the first and second sensors are changed in accordance with a distance to a sheet of the roll sheet. A rotation direction of the roll sheet is switched from a forward direction to a reverse direction on the basis of the outputs of the first and second sensors while the roll sheet is being rotated in the reverse direction.
