PURPOSE:To transmit accurately the contents of emergency in an emergency, by calling a called subscriber through an originating means and actuating a voice generating means recording the message contents after the remote side gives a reply. CONSTITUTION:A switch showing a prescribed called subscriber is pushed through a switch means 2, and then an originating signal (a) is supplied to a circuit L1 from an automatic dial mechanism 1A. When the called subscriber gives a reply, a receiving signal (c) is supplied to a receiver 4 through a circuit L2. A signal (c') is supplied to a voice generator 3 when the signal (c) is supplied to the receiver 4. Then an audio signal (b) which transmits the contents of emergency is supplied to a transmitter 1. In this case, the signal (c') is simultaneously supplied to a switching function 1B, and the signal (a) is switched to a signal (b) to be sent to the circuit L1. When the signal (c) is cut off, the oscillation of the signal (b) is automatically stopped. In such constitution, it is possible to report easily and accurately an emergent state with just a single button operation in an emergency. |
