Abstract
PURPOSE:To disable the drive of an engine due to direct connection of an electric system or the like, by enabling the engine to be started in association with identification of a mechanical key and identification of electronic codes, and by stopping an engine if any unsatisfactory identification is detected after a start of the engine. CONSTITUTION:When a key is turned, a contact 9 makes contact with the associated contact 10, and when a contact circuit 17 delivers a signal for confirming the above-mentioned contact to a trigger circuit 14, a CPU 13 issues an inherent signal so as to allow a light emitting element 8 to transmit an infrared code signal to a light receiving circuit 11. If the inherent code is not coincident with the infrared code until a predetermined period elapses from the time when the CPU 21 receives an engine start confirming signal from an engine control device 27, the CPU delivers an engine stopping instruction to the engine control device 27 through an input and output device 25 so that the control device 27 stops an engine ignition device 32 and the fuel injection device.
