Abstract
A roll paper printer includes a container that can accommodate a roll paper around which a recording paper sheet is wound with its first surface facing outward. A transport roller pulls the recording paper sheet from the roll paper and then transports the recording paper sheet in a transport direction. A guide can be in contact with a second surface of the recording paper sheet at a location upstream of the transport roller in the transport direction. A projection can be in contact with the first surface of the recording paper sheet at another location upstream of the transport roller in the transport direction and move toward the guide. A lever can be accommodated in the projection and move in contact with the first surface of the recording paper sheet. A sensor is accommodated in the projection and detects motion of the lever.
