    摘要： 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.

    摘要： A power source circuit includes a first converter, a second converter, a switch and a controller. The switch is configured to switch between a first state and a second state, in which in the first state, a first voltage is not supplied to the second converter whereas in the second state, the first voltage is supplied to the second converter. The controller controls the switch to change the first state to the second state in response to detection of the change in a first current flowing in a first load. The second converter is configured to convert a battery voltage of a battery to a second voltage lower than the battery voltage when the switch switches to the first state and convert the first voltage to the second voltage lower than the first voltage when the switch switches to the second state.

    摘要： A method of controlling a printer includes measuring a first voltage value of a power supply of the printer before energizing heat generating elements of a print head of the printer. The method also includes calculating, by a controller of the printer, the number of heat generating elements that are simultaneously energizable based on the measured first voltage value of the power supply, an end voltage value of the power supply, an internal resistance value of the power supply, a resistance value of each of the heat generating elements, and a current value of an electric current flowing through a motor of the printer for conveying recording paper. The method further includes performing printing on the recording paper by the print head using the heat generating elements of the calculated number.

    摘要： Generally, in accordance with embodiments, a thermal printer comprises heating elements, a storage section, a drive circuit and a controller. A plurality of heating elements are linearly arranged. The storage section stores a one-line amount of image data. The drive circuit energizes each heating element according to the one-line amount of image data. An acquisition section acquires an A/D value corresponding to the voltage applied to each heating element every time each heating element is energized. The controller outputs a one-line amount of empty data to the storage section to acquire a first A/D value with the acquisition section, reduces, based on the first A/D value, noises of a second A/D value which is acquired by energizing each heating element and checks the disconnection of each heating element based on the noise-reduced second A/D value.
