| description | PURPOSE:To perform the head temperature control of the thermal printer with a high control speed for a simple power supply device light in weight with a violent fluctuation of power supply voltage by adding the fluctuation of the supply voltage with a rapid response of the temperature fluctuation to one of the cause of the temperature control. CONSTITUTION:The current is supplied from a heat source 1 through a pulse width modulation means 2 to many resistance heat generators (r) in a head 3. The heating energy is controlled by increasing or decreasing the pulse width tauby the pulse modulation means 2. A supply voltage fluctuation corresponding block 6 is constructed by a supply voltage measurement means 7 and a pulse width conversion means 8. In the supply voltage measurement means 7, supply voltage VSUP is measured and the result is inputted to the pulse width conversion means 8 as a second input. The output signal after conversion of the means 8 is added to the means 2 as a modulation signal. As a result, the pulse width of the heating voltage to be applied to the head 3 is modulated to be wider when the supply voltage is low and to be narrower when it is high. |
