ABSTRACT:
A thermal recording apparatus for use in a facsimile recording apparatus or the like. Thermal resistors arranged in a thermal recording head are divided into a predetermined number of groups. By group-selection circuits which constitute constant-voltage circuits and which are provided correspondingly to the groups of thermal resistors, the thermal resistors are actuated in a time-divisional manner so as to record image information on a thermosensitive recording paper, whereby each constant voltage circuit with a relatively small capacity is actuated in a time-divisional manner for driving the recording head. Thus, a regulated power supply apparatus with a large capacity is not required, so that the power consumption of the recording apparatus can be reduced and the size thereof can be decreased.
