By the identification signal from the first transmitting means 10a, each of a plurality of moving bodies such as a racing car participating in the race can be distinguished. In the present invention, the reason why the so-called two-way system in which the mobile body does not always send the ID identification signal but sends it only when the ID request signal is received is that the ID identification signal transmission consumes a large amount of energy. This is to allow the used battery to be used for traveling as much as possible. As the second transmitting means 20a and the first transmitting means 10a, a light emitting device using an infrared LED as a light emitting body used for the transmitting means is preferably used.

Further, it is preferable that the first transmitting means 10a is equipped with a stabilized power supply device therein, so that various power supplies can be supported. For example, the traveling power supply voltage and the receiver power supply voltage may be different depending on the moving body, but if a stabilized power supply is mounted inside each of them, it can operate without problems. Further, by mounting the stabilized power supply, there is also an advantage that it is not affected by changes in the power supply voltage during traveling.
