Abstract: An object is to provide a thermal transfer printer having an inexpensive configuration and capable of making a tension given to an ink ribbon as constant as possible, even when a secular change and an environmental change occur in a DC motor used as a supply motor and a winding motor. A supply motor control unit controls a supply motor of an ink ribbon supply unit. A winding motor control unit controls a winding motor of an ink ribbon winding unit. A remaining amount detection unit detects a remaining amount of an ink ribbon. A variable calculation unit acquires parameters for an armature current, an applied voltage, and a rotational speed of each of the supply motor and the winding motor, and calculates variables to be used for controlling the supply motor and the winding motor on the basis of the acquired parameters.

Abstract: An object of the present invention is to provide a thermal printer having a paper feed mechanism capable of readily loading paper pulled out from a roll of paper and capable of readily feeding sheets of paper. A first housing is capable of coupling to and decoupling from a second housing. The first housing includes a paper edge severance guide unit configured to sever a leading edge of the sheet of paper from a roll state of the rolled paper, and guide the sheet of paper toward the platen roller, feed rollers configured to perform gripping of the sheet of paper and conveyance of the sheet of paper in the direction of the platen roller, and a paper stopper configured to block a passage for transporting the sheet of paper in a state where the first housing is decoupled from the second housing.

Abstract: A thermal printer uses an ink ribbon having a function of performing cleaning of a thermal head by being heated. The thermal printer performs a cleaning process of performing cleaning of the thermal head. In the cleaning process, the thermal head applies, to the ink ribbon, heat of a heat quantity with which a dye applied onto the ink ribbon does not sublime and with which the cleaning is performed.

Abstract: A first cutter 130 (cutting unit) is provided between a color recording unit 120 (the first printing unit) and an overcoat recording unit 140 (the second printing unit). A portion whereon color printing is completed by the color recording unit 120 of a recording paper 200 (printing medium) is cut off by the first cutter 130 and detached. An overcoat recording unit 140 performs an overcoat process on the detached recording paper (printing medium strip). In parallel with this, the color recording unit 120 performs next color printing on the recording paper 200. This makes it possible to reduce a printing time in a printing device including a plurality of printing processes without deteriorating printing quality. Further, an useless paper feeding is eliminated by optimally arranging the color recording unit 120, the first cutter 130, the overcoat recording unit 140, and the second cutter 160, etc. in accordance with a size of a printing area.
