CONSTITUTION:A memory means 14 to register an incoming rejection telephone number to be identified, a comparing means 12 to compare the received caller number with the number registered in the memory means 14, to output the incoming rejection signal at the time of a coincidence and to output an ordinary incoming signal at the time of a non-coincidence, and interruption and incoming operating means 7, 8 and 11 to execute the procedure of the incoming rejection based on the incoming rejection signal from the comparing means 12 or to execute the procedure of an ordinary communication based on the ordinary communicating signal from the comparing means 12, are provided.
