<P>PROBLEM TO BE SOLVED: To save space in a ultra-compact television receiver. <P>SOLUTION: The emitter of a transistor 4 is connected to a voltage line A supplied from an AC adaptor 1, the base of the transistor 4 is connected to a power supply microcomputer 2, and the collector of the transistor 4 is connected to a reset signal line B via a diode 6. Thereby, the drop in reset voltage, caused by the drop of a supply voltage from the AC adaptor 1 due to a rush current on the turning-on of the power, is backed up by the transistor 4, and the momentary reset malfunction upon the turn-on of the power is prevented. <P>COPYRIGHT: (C)2004,JPO |
