Abstract

PURPOSE:To improve the function of locking and manipulation while increasing the number of combinations, by providing an electronic locking circuit which when at least not less than two fixed channel selection switches are operated in fixed order, detects and operates them. CONSTITUTION:Between DC electric power source circuits 3 and 4 for receiver 2 and main electric power source 1, main electric power source switch 5 and switching element (relay) 6 are interposed in series and the contact of relay 6 stays to transformer 10. Further, detecting circuit (electronic locking circuit) 13 is driven by DC electric power sources 11 and 12 and transistor TR14. Circuit 13 consists of channel selection switch 15, encoder 16, shift transistor 17, preset switch 18, and comparing circuit 19. With one of switches 15 operated, conversion 16 into binary codes is performed and after another switch is operated, its signal is transferred to register 17 successively to make comparison 19 between its contents and preset-18 contents, so that when the two agree, detection output 14 is generated to drive TR14 and then circuit 13. Driving relay 6 cuts off the electric power supply to circuit 13.
