Abstract: PURPOSE:To enable the temperature of a thermal head to be maintained in a temperature range independent of the ambient temperature, by applying the quantity of energy smaller than the minimum energy necessary for thermal transfer, to heat generating elements not to be operated for thermal transfer. CONSTITUTION:A controlling circuit comprises an n-bit shift register 4 for n heat generating elements 31..., a data (i) transmitted in synchronism with clock pulses CK, and are latched into latch circuits 51 by latch pulses LP.
