Abstract

PURPOSE:To always fix voltage to be applied to a heat-generating resisting body, regardless of number of graphic signal to be recorded, by fixing voltage of source driver for selective electrification and heat generation of a heat-generating resisting body for radiation of a heat-sensible recording paper. CONSTITUTION:By providing a terminal 10 for turning on-and-off of a constant voltage source driver 9 on the constant source driver 9 (this is actually consisting of 91-9n) to be connected to a DC non-stabilized power source (rectifying circuit) 8, the constant voltage source driver 9 fixes voltage of output terminal to a constant voltage regardless of the load current. The constant voltage source driver 9 is composed, for instance, of a Zener diode, a transistor 12 for small signal, a transistor 13 for control and a resisting body 14. As for another example of actual use, it is also possible to increase voltage of the DC constant voltage power source by voltage drop of the source terminal by detecting voltage of the source terminal.
