Claims

[Scope of utility model registration request]

A portable transmitting device that transmits radio waves with a specific code at a constant output, a reception decoding means that receives and decodes the radio waves sent from the transmitting device, and outputs a signal when it matches a pre-input registration code, and a drive signal. a circuit switching means for inputting the driving signal to the notifying means in response to the output state of the receiving and decoding means; a receiving device comprising a changeover switch capable of changing over the drive signal so as to output a notification sound of 2; the changeover means and the changeover switch share the reception decoding means and the notification means and are interposed between the two means; When the distance between the person carrying the transmitting device and the person carrying the receiving device becomes such that the radio waves cannot be received and the matching signal output from the reception decoding means is interrupted, the first switch is activated. A second notification sound is emitted when the person carrying the transmitting device and the person carrying the receiving device are close enough to receive the radio waves and a matching signal is output from the reception decoding means. An interpersonal communication device outputting from the notification means, respectively.
