The voltage supply to the power supply is stopped, and naturally the clock timing unit 41a is also stopped. Then, by exchanging the main power supply 13, each unit of the apparatus and the clock / timer unit 41a restart their operations.

FIG. 2 is a block diagram of a base unit 50 in a wireless telephone. In FIG. 2, the same components as those of the base unit 20 shown in FIG. The description is omitted.

In FIG. 2, the control unit 51 is a CPU

Next, the operation of this embodiment will be described.

First, in the slave unit 40 shown in FIG. 1, when the telephone number of the other party's telephone is input and a call is instructed by a key operation on the operation unit 11 by the operator, the control unit 41 is operated.
Starts the calling process, converts the inputted telephone number information and control information for controlling the calling procedure into a transmission signal of a predetermined radio frequency by the RF unit 12, and the antenna 2 shows the transmission signal as shown in FIG. It transmits to the master device 50.

When the master unit 50 receives a radio signal including a call request from the slave unit 40, a communication procedure for making a call with the destination telephone via the public line connected to the line control unit 25. Communication is started and started, and communication control information relating to a call according to the progress status of the communication procedure is exchanged with the handset 40, and the handset 4
The call connection between 0 and the destination telephone is terminated.

After the call connection is completed, the call between the handset 40 and the destination telephone is started.

In the slave unit 40, the operation of each unit of the apparatus and the clock / timer unit 41a is stopped due to the decrease in the voltage value supplied from the power supply control unit 43. Then, when the main power supply 13 is replaced and the recovery of the voltage value supplied from the power supply control unit 43 to the respective units of the device and the clock timing unit 41a is detected, a radio for requesting the master unit 50 to transfer the clock information is transmitted.

This will be described with reference to the flowchart of the communication process of the child device 40 and the flowchart of the communication process of the parent device 50 shown in FIG.

In FIG. 3, first, the control unit 41 in the slave unit 40 includes a power supply control unit 4 in each unit of the apparatus and a clock / timer unit 41a.
When the recovery of the voltage value supplied from the wireless communication unit 3 is detected, the clock information transfer request information is transmitted from the RF unit 3 and the antenna 2 to the parent device 50 by a predetermined wireless signal (step S in FIG. 4).
1).

The master unit 50 sends a radio signal including the clock information transfer request information from the slave unit 40 to the antenna 21 and the RF unit 2.
When receiving via 2, the control unit 51 transmits a request acceptance signal from the RF unit 22 and the antenna 21 to the handset 40,
The fact that the clock information transfer request information has been received is transmitted to the child device 40 (steps S11 and S12 in FIG. 5).

Next, in the master unit 50, the clock timing unit 51a
The clock information clocked at is read out and transmitted as a predetermined wireless signal from the RF unit 22 and the antenna 21 to the slave unit 40 (step S13 in FIG. 5).

Next, in the slave unit 40, the radio signal including the clock information transmitted from the master unit 50 is transmitted to the antennas 2 and R.
When receiving via the F unit 3 (step S3 in FIG. 4), the control unit 41, based on the received clock information, the clock time counting unit 4
The time in 1a is reset and the clock timing operation is restarted (see FIG.
Step S4), the incoming call response signal is transmitted from the RF unit 3 and the antenna 2 to the master device 50, the master device 50 is notified that the clock information has been received, and the communication process ends (step S5 in FIG. 4). ).

Upon reception of the incoming call response signal from the child device 40, the parent device ends this communication processing (step S14 in FIG. 5).

As described above, in the radio telephone of this embodiment, when the main power supply 13 for supplying the voltage to the slave unit 40 is replaced and the voltage which has been stopped is restored, the master unit 50
A request for transfer of clock information is made to the device, and the time of the clock timekeeping section 41a is reset based on the transferred clock information. Therefore, in the slave device 40, when the voltage generated by the main power supply 13 drops, A sub-power supply for compensating the operation of the timekeeping unit 41a and the like is unnecessary, and switching control from the main power supply to the sub-power supply in the power supply control unit 43 can be unnecessary, and the manufacturing cost of the slave unit 40 can be reduced. it can.
Further, since the setting operation for setting the clock is unnecessary, the function of the wireless telephone can be improved.

In the above embodiment, the case where the slave unit 40 requests the master unit 50 to transfer the clock information is shown. However, when the power supply by the power unit 32 of the master unit 50 is stopped due to a power failure or the like. Also, when the power supply unit 32 returns, the main unit 5
A clock information transfer request is transmitted from 0 to the slave unit 40, and the clock timing unit 5 is transmitted based on the clock information transmitted from the slave unit 40.
It is also possible to reset the time of 1a.

Further, when the time counting operation is stopped, the time count is reset, that is, set to "0:00, etc.", and the time data is compared between the slave unit and the master unit to become "0:00". It is set so that the one who keeps the timekeeping operation transmits the clock information from the one who continues the time counting operation and the time data of "0:00" is adjusted to the correct time data. It is also possible to do so.

Further, in the above-mentioned embodiment, the case of setting the time in the wireless telephone has been described. However, in the case where the time data is set and displayed on both the main body and the remote control device in the home electric appliances, the data of the present invention is set. A setting method can be used.

For example, in a remote control device for remotely controlling a video device and a video device, the remote control device side stops the clock due to exhaustion of the battery, and transmits a clock information transfer request to the main body using the remote control signal after battery replacement. Then, the main body side can recognize this clock information transfer request and transmit its own clock information to the remote control device by using the remote control signal to reset it to the correct time.

In the above embodiment, only the time data is set, but the present invention is not limited to this, and other data such as telephone directory data may be used.

Therefore, a backup power supply and a reset operation are not required between the devices having the communication function,
Data can be easily reset between both devices using the communication function.

[0045]

According to the data setting method of the present invention, it is possible to easily reset data between both devices by utilizing the communication function without requiring a backup power source or a reset operation.
