A top cover and a guide member form a discharge port. A plurality of guide ribs is provided on an edge portion of the top cover. A plurality of projecting pieces is provided on a guide member at positions not to face to the guide ribs. These guide ribs and projecting pieces are used for guiding a roll sheet to a discharge port. At least one of the guide ribs is provided with an extended portion extending upstream in a feeding direction to prevent the roll sheet 3 A from curving in a direction vertical to the feeding direction. Thus, the inability to discharge the roll sheet can be avoided.
