PROBLEM TO BE SOLVED: To provide an incoming call notice device for a portable telephone set in which an incoming call state of the portable telephone set not having a vibration incoming call state notice function is informed through vibration. SOLUTION: A blink state of an incoming call lighting display section 2 of a portable telephone set 1 is detected by a photo transistor(TR) 4, a signal denoting the detected state is amplified by an amplifier TR 7, detected by detection diodes 10, 12 to activate a switching TR 11 and then to activate TRs 16, 18 of a Darlington connection circuit 15 thereby applying drive control to an eccentric motor 17 and vibrating a vibration generating mechanism to inform of the incoming call reception state. The vibration generating mechanism may be configured integrally with an adaptor A or provided to a separate incoming call notice section. |
