Abstract

PURPOSE: To reduce the power consumption by inserting the switching element between the power source and the power input terminal of the microcomputer and thus controlling the input of the power supply by the computer itself only for the time when the computer operates.
CONSTITUTION: Switching transistor TR is inserted between power source E and power input terminal V of microcomputer MC; one terminal OT of the output with ratch of MC is connected to the base of TR via resistance R3; and the base is earthed via resistance R4. At the same time, one terminal IN of the MC input is earthed via resistance R1, and at the same time power source E is connected to the collector of TR via switch S. Furthermore, the junction between switch S and resistance R1 is connected to diode D2 via R2, and the other terminal of D2 is connected to the base of TR. Thus, the output ratch is set up by the initial set program when switch S is operated.
