Abstract

PURPOSE:To realize an assured ON/OFF control of the part to be controlled regardless of the speed of ON/OFF of the power source, by setting the ON of the memory power source part slower than the ON of the control part power source and at the same time setting the OFF of the memory power source part faster than the OFF of the control part power source respectively. CONSTITUTION:The rise of a smoothing circuit consisting of the resistance 22 and capacitor 23 is set slower than the rise of the output voltage of the voltage stabilizing circuits 10 and 12. As a result, the memory power source part is turned on after the output voltage of the waveform shaping circuit 18 is set at a low level. Accordingly the ON of the memory power source part is set slower than the ON of the control power source part. On the other hand, the voltage of the above-mentioned smoothing circuit falls suddenly by a low impedance of the Zener diode 24 when the power source is off. As a result, the transistor 28 is cut off, and the memory power source part is turned off faster than the control power source part.
