Abstract (en)
In a new communication game system using communication, two kinds of communication game devices are realized with the same hardware and by differentiating their active modes. Communication between a communication game device of the first kind and a communication game device of the second kind is made by differentiating the transmitting frequency of the first kind device and the transmitting frequency of the second kind device from each other. A unmodulated pulse is transmitted at a specified frequency, and the pulse duration is changed with message. When a communication game device of the second kind receives a signal having a message from the communication game device of the first kind, the device of the second kind makes an annunciation and transmits a responding signal if the received message is in accord with the message of its own. The communication game device of the fist kind make an annunciation when it receives a responding signal.
