PROBLEM TO BE SOLVED: To prevent the increase in the device cost and making the device larger while evading the influence of noises and the characteristic deterioration of a radio part by cutting the power that is supplied to a notification means from a power supply while a receiving means is operating. SOLUTION: A control part 102 outputs a control signal for intermittently operating a radio part 101 and also to turn on a switch 104 to operate a vibrator 103, when a call addressed to the part 102 itself is received. A power supply 105 supplies the power to both parts 101 and 102 and the vibrator 103. In this case, the operating of the vibrator 103 is inhibited in timing, when the part 101 operates. In other words, the vibrator 103 is separated from the supply 105 via the switch 104, when the part 101 is turned on. Thus, the part 101 being affected adversely by the drive noises of the vibrator 103 can be avoided. Furthermore, the current consumption is reduced since no voltage drop exist in the supply 105 and no current flows to the vibrator 103. |
