れる危険性がある。In the case of this type of electronic key, in which an encoded infrared signal is sent from the transmitter and decoded by the receiver, if someone is within the radiation range of the infrared transmitter during transmission, the encoded There is a risk that the transmitted signal will be received and stored by an infrared receiver somewhere.
このようOτして比較的簡単に電子鍵を模写することか

において、このような電子鍵の便利な取扱いに反するこ
とになる。The possibility of V copying mentioned above can only be prevented if the transmitter and receiver are placed so close together that no other receiver can be placed in the radiation area of the transmitter. however,
On the one hand, this is inconvenient because the receiver is installed inside the car, and it is impossible to practically prevent reflections from windows, for example. , which goes against the convenient handling of such electronic keys.

No. 51211, Specification 1. According to this, it is basically possible to change the sign, which makes it difficult to use the motor vehicle illegally. There is a danger that the codes of the transmitter and receiver may be adjusted to be different from each other, making it impossible to open the car with the key.Also, each time the user unlocks the key, the transmitter and receiver will have a new code. Since the above-mentioned possibility of copying 0] does not preclude illegal use of automobiles.

The object of the present invention is to provide a code security method for electronic keys of the type mentioned at the beginning, such that if the device and the receiver are not synchronized, they can be easily resynchronized.

。According to the present invention, the code sent out from the transmitter is determined by the receiver V, which code number should be selected as the next code number from the stored 4N contents.
This is solved by including information for C.
受信器(は、コード番号を高める方向にのみ後同期を受
け入れるよう(Cすると有利である。It is advantageous for the receiver to accept post-synchronization only in the direction of increasing code numbers.
また受Gf器は、コード番号の狭い間1隔においてのみ
後同期を受け入れるよう+CするとM利である。Further, the receiver Gf device has an M advantage when +C is applied so as to accept post-synchronization only in one narrow interval of code numbers.

, this photodiode sends out an infrared signal 5, which is detected by a phototransistor 6. The infrared signal 5 is encoded and additionally contains information for the receiver 2 as to which code number is to be selected as the next code number from the stored contents. The signal of the transistor 6 is transmitted via an amplifier 7 to the receiver 2 and produces a signal 9 at the output 8 of the receiver 2, which signal causes the central chain disconnection device of the motor vehicle to be activated by the driver 11?
