PCT No. PCT/JP82/00223 Sec. 371 Date Feb. 1, 1983 Sec. 102(e) Date Feb. 1, 1983 PCT Filed Jun. 9, 1982 PCT Pub. No. WO82/04487 PCT Pub. Date Dec. 23, 1982.Herein disclosed is a vehicular power source system which uses as its load a memory-arithmetic circuit (5) such as a microcomputer. An electric power is supplied to the load (5) through a diode (6) and a constant voltage circuit (4), when a switch (2) for running the vehicle is open, but a booster (3) is operated to supply the power when the switch (2) is turned on. The voltage drop of a battery (1), which may be caused during the running operation of the vehicle, is not transmitted to the load (5), but a constant voltage is supplied to the load (5) at all times so that the storage data of the memory unit (5) is always held. |
