Abstract

PURPOSE:To attempt to simplify the construction of a thermo sensitive recorder by preventing erroneous operations of its electrical circuit parts such as relay, solenoid, transistor, etc. by the adoption of such an arrangement wherein a power source for driving the drive circuit of a thermal head is supplied only when a power source for controlling is supplied to the device. CONSTITUTION:When the power switch of a power circuit shown in the figure is turned ON, a self-exciting oscillator 13 operates and a power source for controlling (a) is generated at the output side of a rectifier circuit 16 and simultaneously a relay 11 operates and turns a realy contact ON. By the generated power source for controlling (a), a control circuit 2 operates to cause an oscillator 14 to operate and by this a power source for driving (b) is generated at the output side of a rectifier circuit 17. By using such a power source unit as stated above wherein a power source (b) for driving is supplied only when a power source (a) for controlling is being generated in a thermo sensitive recorder as its power source unit, such erroneous operations of its electrical parts than may take place when a power source for driving is supplied during such a period when a power source for controlling is not supplied can be prevented.
