ABSTRACT:
In a thermal recording apparatus according to the present invention, when recording paper having a maximum width is set, no solenoids operate. A thermal head supported by a support energized by a spring is thus pressed against a platen roller. An image is thermally formed by a resistance heating element array of the thermal head on the recording paper supplied between the platen roller and the thermal head. When small-sized recording paper is supplied, sensors detect a leading edge of the paper. The controller turns on the solenoid of an assembly in which a thermal head which does not participate in the recording is provided. Thus, a drive shaft of the solenoid retracts to space the support away from the platen roller. The thermal head and platen roller of the assembly are spaced from each other, and a platen roller which the recording paper does not pass is prevented from contacting on the thermal head. The waste of power required for driving the platen roller is thus avoided.
