Abstract

PURPOSE:To obtain the titled device, wherein a driver and a temperature sensor are mounted on a substrate, a current conduction time and an applying voltage to a heating body are controlled in response to a recording data pattern and the output of the temperature sensor, the control is simplified, and printing quality is improved. CONSTITUTION:A heating body 2, a driver 3, and a temperature sensor 5 are mounted on a same substrate. Thus the scale of a circuit is made small, a device is made compact, and control is simplified. Feedback control is performed in a control circuit 7 in response to the output of the temperature sensor 5, which is mounted on a serial printing thermal head 6. Thus the recording density is made uniform.
