Abstract

A received telephone number is classified into group and stored by a simple operation, and is used as the telephone number when making a call.

It comprises a telephone number detector (2) for detecting an incoming telephone number from a telephone line, an operation unit (13) for specifying the group of the detected telephone number, a memory (11) for storing the information of the specified group and the telephone number in correspondence, and LED (15a-15d, 19a-19b) for displaying multiple colors. In the incoming operation, the lamp color is changed to display which group the received telephone number belongs to, and the call receiver easily recognizes the call is from which specific group. Further, when dialing by making use of the stored telephone number, the telephone number is displayed and searched in each group.
