The main body device which has transmitted together with the signal turns on the power of the main body of the apparatus and sets the received time information in the internal clock circuit. After setting, the clock is stepped in synchronization with the frequency of the power supply and the time is displayed.

FIG. 1 is a block diagram showing the configuration of an electric device according to an embodiment of the present invention. The remote control transmitter 1 is provided with a clock unit 2, and by pressing an operation key, a remote control signal corresponding to the operation is converted into infrared rays or radio waves and transmitted, which is received by the receiving circuit 3 of the main body device 11. It operates according to the desired operation. When the power ON key 1a provided on the remote control transmitter 1 is pressed, the power ON signal and the time information signal of the clock unit 2 provided inside the remote control transmitter 1 are transmitted together and received by the receiving circuit 3 of the main body device 11. To be done.
After the power-on data and the time information data in the received remote control signal are discriminated by the signal decoding circuit 4, the power-source frequency component extracting circuit 7 is started by the power-on data.

The time data is temporarily stored in the time data holding circuit 5, passes through the switching circuit 8, and advances to the clock step circuit 6.
The time value of the clock of the main body device 11 is set (reset) according to the time data sent and received. The part for setting the time from the time data holding circuit 5 to the clock step circuit 6 via the switching circuit 8 corresponds to the clock setting means. If this time data is output to the time display circuit 9 and displayed on the clock display unit 10, the time corresponding to the transmission data is displayed.

After resetting the time value of the clock of the main body device 11, the switching circuit 8 connects the signal line to the clock step circuit 6 to
The signal line from the power frequency component extracting circuit 7 is switched and connected. The power supply frequency component extraction circuit 7 is connected to the power supply signal line from the power supply plug 12, and is 50 for a household power supply.
The frequency component of Hz or 60 Hz is taken out and input to the clock step circuit 6 to step the clock in synchronization with the frequency of the power supply. The portion that advances the clock stepping circuit 6 from the power supply frequency component extracting circuit 7 through the switching circuit 8 corresponds to the clock stepping means. The time data of the stepped time is displayed on the time display circuit 9

When the power ON key 1a of the remote control device 1 is pressed while the power of the main body device 11 is already turned on and the clock in the main body device is operating, the reception circuit 3 of the main body device 11 receives the signal. To be done. The power ON data and the time information data in the received remote control signal are discriminated by the signal decoding circuit 4, and the power ON data is detected. The power supply frequency component extracting circuit has already been operated, and continues to operate without being affected by the power ON signal.

The time data received by the receiving circuit 3 is temporarily stored in the time data holding circuit 5. When the power ON signal is detected, the switching circuit 8 is switched by the control circuit (not shown), and the data stored in the time data holding circuit 5 is sent to the clock stepping circuit 6 through the switching circuit 8 and the main device The time value of the clock 11 is reset according to the received time data. Alternatively, the switching circuit 8 is switched by detecting the time information signal stored in the time data holding circuit 5.

After resetting the time data of the clock of the main unit 11, the switching circuit 8 switches and connects the signal line to the clock step circuit 6 to the signal line from the power frequency component extracting circuit 7. The power supply frequency component extraction circuit 7 is connected to the power supply signal line from the power supply plug 12, and extracts the frequency component of 50 Hz or 60 Hz in the household power supply and inputs it to the clock step circuit 6 to synchronize the power supply frequency with the clock.

Since the remote controller is provided with a clock function and the main body device is operated by adjusting the clock only when it is in operation, it is usually necessary to turn on the minimum power supply for receiving the remote control signal to the main body of the device. The power consumption can be reduced even when the clock is constantly operated. The clock provided in the remote control can be maintained in operation with a dry battery for the remote control power supply. Therefore, it is possible to prevent the malfunction of the timepiece due to the power failure.

When the power is turned on, the time information is transferred by simply pressing the power ON key of the remote controller without performing a special operation for time adjustment, and the clock can be operated at the correct time. As a result, the time is set when the power is turned on, so it is possible to save the trouble of performing a special time setting operation, and when using the main unit, the clock operation set (reset) according to the clock of the remote control You can get the display.

For the maintenance of the timepiece, since the small and light remote controller is provided with the timepiece function, it is possible to easily confirm the time, replace the battery, and correct the time by hand.
You can use it while maintaining the correct time. Since the power consumption of the remote controller is small, the time on the remote controller side can be correctly maintained by providing a small rechargeable battery, a charger, or the like as a backup to the remote controller as a measure for removing the battery.

Although the power-on key of the remote controller is taken as an operation key here, if any other operation key is used to perform signal transmission accompanied by power-on, similarly, the power-on signal is used together with the time. Information signals may be sent to implement the invention.

[0017]

According to the present invention, when the remote control device is turned on, the time information in the remote control device is transmitted to set the time value of the clock of the main device, so that the main device is used. When doing
It is possible to save time and labor for time adjustment operation and display the time-adjusted clock. Further, according to the present invention, since the clock of the main body device is reset by performing the power-on operation by the remote control device while the power is on to the device, it is not necessary to be aware of the special time adjustment operation. , The clock can be set by the remote control device by the same operation as when the power is turned on. Further, according to the present invention, since the power supply frequency is extracted and used as the reference signal for stepping the timepiece of the main device,
A reference signal source is not required in the main device, the device configuration is simplified, and power consumption can be suppressed.
