PROBLEM TO BE SOLVED: To prevent the mistaken start of an engine by beginning the holding of the result of recognition carried out through cord recognized holding means after specified time from the outputting of the result of recognition from CPU. SOLUTION: The inside of a key 1 is provided with a CPU 9 for controlling the transmission of a cord signal and an ID memory section 10 for storing the user ID of the cord signal. The CPU 9 reads the user ID from the ID memory section 10 and emits its cord signal from an infrared emission section 5 by input of a turn-on signal for a transmission switch 4. The inside of a CDI unit is provided with a CPU 12; an ID memory section 13 having stored the user ID the same as the key 1; a CDI basic circuit section 14 for controlling an ignition; and a power source circuit section 15. The CPU 12 compares a cord signal received by an infrared receiving section 11 with a cord signal stored in the ID memory section 13, and carries out the distinguishment of whether it is right or wrong; a digital ignition control; and the charging of recognized capacitor CI. Even if the CPU 12 is intentionally run away, since the charged voltage of the recognized capacitor CI is set up not to reach a threshold zone, a burglary carried out by the wrong start of an engine can be prevented. |
