PURPOSE:To easily confirm the fact that a message is transmitted normally to a callee, by detecting a caller address signal included in a message signal, and returning a signal required for a caller. CONSTITUTION:The caller transmits a numeral or a mark equivalent to the message signal including a response request signal and an address signal from the nearest telephone set, etc. The microcomputer 13 of a reception part extracts a call signal out of the message signals, and compares the call signal with its own number stored in a memory device 14, and when they coincide, displays a reception message on a display device 18. At this time, if the response request signal is outputted, the computer 13 extracts the caller address signal from the message signal, and sends a confirmation message, etc., to the caller based on the caller command of the callee. |
