ABSTRACT:
A tape printer for securing a time period sufficient for processing printing data even if the rpm of a DC motor increases, when an encoder is used for detecting rotation of the DC motor. When the DC motor does not rotate at a constant speed, in principle, the encoder detects an amount of rotation of the DC motor. Accordingly, a thermal head is driven for printing, every time a predetermined angle of rotation is sensed. On the other hand, when the DC motor rotates at a constant speed, the thermal head is driven for printing at constant intervals.
