TELEPHONE SET SYSTEM

PURPOSE:To transmit smoothly a message even if a transmission destination is absent by storing a message data inputted via an input device, transmitting the data to a selected telephone set and storing the data to a storage device of a transmission destination telephone set via a telephone circuit. CONSTITUTION:All functions of a telephone set 1 are displayed on a display device 4 by hooking off a handset 2 or depressing a loudspeaker button 3. Then an input pad 6 of the input device 5 is operated to select the function transmitting the message data and the data is displayed to the device 4 and the message data is stored in a message data storage register 8. Then the message data is transmitted from a message data transmission/reception circuit 10 by depressing an ''SEND'' key. Since the content to be communicated is stored in the message data storage register 8 of the destination as the message data such as characters or graphs, even if the destination is absent, the message is transmitted smoothly.
