PURPOSE:To improve burglar preventive effect on a vehicle by providing both a means sotring password numbers and a means judging whether or not an inputted password number is in a good agreement, and thereby using the actuating section of an on-vehicle acoustic device which can be remotely controlled as a password number inputting means. CONSTITUTION:When an actuating switch 4 is actuated in order to actuate an acoustic device 8 and a locking device 9 in a remote actuating device 1, let a transmitting code corresponding with the switch 4 be generated by a transmitting section 2 so as to let an infra-red photo-diode 3 be radiated. And let infra-red ray signals generated by the diode 3 be received by each pin photo- diode 5 and 10 of the acoustic device 8 and the locking device 9. And in the acoustic device 8 side, received signals are decoded by a receiving section 6 so as to let necessary control be assumed to an acoustic equipment 7. And in the locking device 9 side, received signals are amplified by an amplifier 11 so as to be decoded by a decoder section 12 thereafter so that they are compared with the password number stored in a non-volatile memory 14. And when both of them are in a good agreement, locking is released with a locking drive section 15 actuated. |
