INCOMING CALL DETECTOR FOR PORTABLE RADIO TERMINAL

PROBLEM TO BE SOLVED: To enable a user to arbitrarily set an ID number or other identification information by providing a memory part for storing and holding identification information read out of an IC card. SOLUTION: The user inserts the IC card, on which the identification information of portable telephone set is stored, into an IC card socket 18 and operates a switch 19 for ID write. An ID compare/read/write part 17 reads the ID number of portable telephone set written on the IC card and writes it into an ID memory part 13. Thus, the ID number of portable telephone set is set to a vibrator 8. The ID compare/read/write part 17 inputs the ID number received from a base station through an antenna 9 and a reception circuit part 10 and compares it with the ID number stored in the ID memory part 13. When the compared result shows coincidence, the ID compare/read/write part 17 generates vibrations by rotating a vibrating motor 15.
