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: In a movable portion state being a state of a print movable portion including a roll core holder unit configured to support one end portion and another end portion of a roll core, there exist an open state and a closed state. The print movable portion is configured to be movable so that the movable portion state is the open state or the closed state. The roll core holder unit is provided with a support portion. In a support state in which the support portion supports the one end portion and the another end portion, as the movable portion state transitions from the open state to the closed state, a first fitting portion fits into the one end portion and a second fitting portion fits into the another end portion.

Abstract: Speed fluctuations are decreased with a simple method even when a stepping motor (100) having comparatively large torque fluctuations is used. A drive pulse modulating unit (112) which modulates the frequency of a drive pulse to be inputted to the stepping motor (100) is provided. The drive pulse modulating unit (112) modulates the constant frequency of the drive pulse such that the frequency of the drive pulse within excitation-phase one cycle of the stepping motor (100) is: low for a period that is, by ? cycle of the excitation-phase one cycle, before an excitation phase where the vibration of the stepping motor is the maximum; and high in an excitation phase that is by ½ cycle subsequent to the excitation phase where the drive pulse frequency is low.

The drive pulse modulating unit (112) modulates the constant frequency of the drive pulse such that the frequency of the drive pulse within excitation-phase one cycle of the stepping motor (100) is: low for a period that is, by 1/8 cycle of the excitation-phase one cycle, before an excitation phase where the vibration of the stepping motor is the maximum; and high in an excitation phase that is by 1/2 cycle subsequent to the excitation phase where the drive pulse frequency is low.

Abstract: A thermal printer of the present invention includes: a thermal head; a platen roller disposed to face the thermal head; a first path that guides a recording paper drawn from a recording paper roll to one entrance of a gap between the thermal head and the platen roller such that a first main surface of the recording paper is on the thermal head side; a second path that guides the recording paper drawn from the recording paper roll to the other entrance of the gap between the thermal head and the platen roller such that a second main surface of the recording paper is on the thermal head side; and a switch guide that switches between the first path and the second path.
