Abstract:
1. A label printer comprising: a housing into which a rolled printing medium is to be mounted; a feeding device which feeds the printing medium mounted in the housing; a printing device which makes prints on the printing medium; a cutter unit including a movable blade that is located at a downstream side of a feeding direction of the printing medium with respect to the feeding device of the printing device, and is reciprocated in a width direction of the printing medium so as to cut a free end portion of the printing medium located at a downstream side of the feeding direction with respect to the printing device into a print label; a feeding plate located at the downstream side of the feeding direction of the printing medium with respect to the printing device; a curved discharge guide provided in a state of rising obliquely upward and successive to a feeding surface of the feeding plate; and a top cover to be placed on the housing, wherein a cutting edge of the movable blade is provided so as to obliquely cross with a direction along which the printing medium is cut, wherein a plurality of long printing medium of different widths is mountable in the housing, wherein any one of the plurality of long printing medium of different widths is mountable in a state where its side end at a specific side is aligned at a common reference, wherein the movable blade has a specific width and the cutting edge is formed at the side of the common reference, wherein the cutter unit includes a ridge side, which is opposite to the side that includes the cutting edge, wherein the movable blade is moved with respect to the printing medium mounted in the housing in the cutting direction from one end opposite to the common reference toward the common reference, and is stopped at a turning point at which the cutting edge of the movable blade goes beyond the side edge of the printing medium located at the side of the common reference, whereas the end portion of the cutting edge of the movable blade at the ridge side does not go beyond the side edge of the printing medium at the side of the common reference, and then is moved from the turning point in a direction reverse to the cutting direction, so that a part of the printing medium is cut into a print label, wherein one end side of a discharge port for discharging the printing medium, the discharge port being located at a downstream side of the feeding direction of the printing medium with respect to the feeding plate, is constituted by an end surface of the top cover, and wherein the printing medium passing through the discharge port slides on the end surface of the top cover which constitutes one end side of the discharge port.
