Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cellular, PHS
And the like. 2. Description of the Related Art Conventionally, in order to notify an incoming call to a portable telephone, there is a method of notifying a sound but using a vibration of a vibrator separate from the telephone. In this system, an ID code is transmitted from a mobile phone so that a vibrator corresponds to the phone on a one-to-one basis.
The vibrator receives this signal and stores the ID
By vibrating when the code matches, the incoming call to the corresponding telephone can be reliably recognized. [0004] However, in order to receive the ID data sent from the mobile phone, it is necessary to always operate each part on the vibrator side. Therefore, the power of the vibrator is wasted. For this reason, the CPU of the vibrator was made to perform intermittent operation, and the power of the receiving unit was periodically turned on to reduce the power consumption of the vibrator.
There is also a possibility that a malfunction that does not operate at the time of an incoming call may occur. An object of the present invention is to provide a means for reducing the power consumption of a vibrator and extending a standby time in view of the above problems. In order to solve the above problems, the present invention provides a receiving unit for receiving an ID code carried by an incoming call notification carrier wirelessly transmitted from a mobile phone at the time of an incoming call. A carrier detecting unit that detects a communication carrier wirelessly transmitted from a mobile phone at the time of an incoming call in a receiving device that vibrates when the received ID code matches the stored ID code; Is detected, the control unit returns from the standby state, and includes a control unit that starts power supply to a receiving unit that receives the ID code. An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing the configuration of the present invention. Reference numeral 1 denotes a portable telephone, for example, means (transmitter, antenna, etc.) for transmitting 1.5 GHz or 800 MHz, which is a normal communication radio wave, and a radio wave for notifying a vibrator 2 described later of an incoming call. A means for transmitting 300 MHz (transmitter, antenna, etc.) is provided. A vibrator 2 for receiving an incoming signal from a mobile phone 1 has two antennas 3 and 4. The antenna 3 is for communication at 1.5 GHz or 800 GHz.
MHz, etc., and the antenna 4 receives 300 MHz for vibration control of the vibrator 2. Reference numeral 5 denotes a CPU that controls each part of the vibrator 2. Reference numeral 6 denotes a carrier (for example, 800 MHz, 1.
Carrier detection unit for detecting 5 GHz or the like), and 300 for receiving 300 MHz for vibrator vibration control.
MHz receiver 8 is an E2PR storing an ID code.
OM and 9 are motors for vibrating the vibrator 2. The CPU 5 is normally in a standby state, and returns from the standby state when the carrier detection unit 6 detects a reception carrier of the mobile phone 1. Therefore, the CPU 5 operates the 300 MHZ receiving section 7.
Is turned on, the antenna 4 and the 300 MHZ receiving unit 7
, Receiving ID data. When a mobile phone 1 receives a call, a vibrator 2
Detects the transmission carrier and returns from standby. Here, the power of the 300 MHz receiving unit 7 is turned on, and the ID data from the mobile phone 1 is received. When the received ID code matches the ID code stored in the E2PROM 8, the CPU 5 rotates the motor 9 to notify the user of the incoming call. As described above, according to the present invention, as long as the transmission carrier of the portable telephone is not detected, the CPU is in the standby state, the power consumption is extremely reduced, and the standby time is extended. Further, the CPU does not need to periodically return from the standby mode, and the timer circuit becomes unnecessary.
