Abstract: This printer performs printing on a print medium having an RFID, and comprises: a communication unit which has a communication part movably provided in a predetermined area along the transport surface of the print medium, and communicates with an IC chip of the RFID; and a detection unit which detects the print medium by means of detection light. The detection unit includes: a light emitting part that emits detection light; a light guide member that guides the detection light emitted from the light emitting part to the print medium; and a light receiving part that receives the detection light via the print medium.

Abstract: An embodiment of the present invention is a thermal head including: a heat dissipation plate having a first surface of a substantially rectangular shape in a plane view, and a second surface that is on an opposite side to the first surface; a board attached to the heat dissipation plat in such a manner as to extend from the first surface to the second surface, via a first end part interposed between the first surface and the second surface; a heating part having a plurality of heating elements, the heating part being disposed on the board over the first surface; and surface-mount devices mounted on the board over the second surface.

Abstract: In a printer for printing on a label of a continuous paper in a middle of feeding the continuous paper unwound from a paper sheet supply unit, while a depressed portion is disposed below a damper portion, a width adjustment guiding portion, which contacts an outer edge in a width direction of the continuous paper to guide a feed of the continuous paper, is disposed on a lower portion of the damper portion such that the lower end portion of the width adjustment guiding portion is positioned within the depressed portion.

Abstract: A printer includes a medium supply unit, a printing unit, a feed unit, which feeds a print medium along a feed direction that is any one of a first direction toward the printing unit from the medium supply unit or a second direction toward the medium supply unit from the printing unit on a reference surface, a depressed portion, which is disposed using the reference surface as a reference, and a movement restricting portion, which includes a guide piece and restricts a movement of the print medium to a direction perpendicular to the feed direction of the print medium by housing at least a part of the guide piece in the depressed portion and abutting a side edge of the print medium on the guide piece, and a side edge on a side of the printing unit of the guide piece is disposed at a position close to an inner wall surface on the printing unit side of the depressed portion with respect to an inner wall surface on a side of the medium supply unit of the depressed portion.

Abstract: At a printer that feeds a continuous paper unwound from a paper sheet supply unit in a sheet-shape to a printing head portion side via a damper portion, and then prints on a label of the continuous paper, the damper portion is made of a transparent material.

Abstract: A thermal printer in which an upper lid portion and a printing unit can be opened off a main body of the printer by a single operation and the upper lid portion is not closed even when a closing direction force is exerted on the printing unit during ink ribbon replacement. The upper lid portion has a stopper 34 that supports an upper lid portion 30 in a predetermined rotative position relative to a main body 20 and releases support of the upper lid portion 30 when the upper lid portion 30 is closed. A unit stopper 44 supports a printing unit 40 relative to the main body 20 at a smaller rotation angle than the upper lid portion 30 and releases support of the printing unit 40 when the printing unit 40 is closed. A connecting member 35 connects the upper lid portion 30 and the printing unit 40 in a fitted state where the printing unit 40 is fitted to the upper lid portion 30.

Abstract: An aligning device for a printing member in a printer in which it is presupposed to use a printer of a one-end supporting structure. The printing member, such as a thermal transfer ribbon 3, can be used by selecting one of center alignment and one-end alignment. A rack and pinion structure within a cylindrical shaft 22 includes a pinion 16 rotatably provided within the cylindrical shaft 22, a pair of racks 17 and 18, a push-in projection 19 configured to push one rack 17 toward the push-in end 22B of the cylindrical shaft 22. A positioning projection 20 is configured to detachably engage with any of a plurality of positioning engagement holes 26 defined in the cylindrical shaft 22 along an axial direction.

Abstract: A thermal printer in which a thermal head can be attached easily to a print unit without requiring a tool such as a screw driver. The thermal printer has a printing unit (40) having a left ribbon frame (43) and a right ribbon frame (42) facing each other. A head housing (60) is attached between the frames (42, 43) while supporting a thermal head (12). A supporting-recess in the surface of the left ribbon frame (43) faces the right ribbon frame (42) and supporting the left side face (64) of the head housing (60). A frame cover (70) is fitted on and removed from a fitting portion provided on the outer surface of the right ribbon frame which is at the back side of the surface facing the left ribbon frame (43) and the cover supporting a right side face (62) of the head housing (60) through a through-hole (50a) formed on the right ribbon frame (42).
