PURPOSE:To easily judge the value of priority to answers by providing a telephone book recording part to store various information at every telephone number and reading the various information on the calling subscriber numbers received in an incoming call mode out of the telephone book recording part to display them. CONSTITUTION:The incoming call signal is received from a circuit connected to a telephone circuit 10 by a signal receiving means 11 for the detection of a telephone incoming call state. While a calling subscriber number detecting means 12 detects the calling subscriber numbers received from the circuit 10 in a telephone incoming call mode. A telephone book recording part (subscriber information memory means) 14 stores previously the information on each subscriber in response to the telephone number. Thus an information reading means 13 reads out the information on the calling subscriber numbers based on the calling subscriber numbers detected by the means 12 and with reference to the means 14 and then displays the read-out information on a display means 15.
