Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic time setting device capable of automatically setting the time of a device having a time setting function.

[0002]

2. Description of the Related Art A conventional time setting device will be described below.

FIG. 2 is a block diagram showing the structure of a conventional time setting device. In FIG. 2, 10 is a device having a clock function, 11 is a time setting switch that can manually set the current time, and 9 is an internal clock that operates based on the time set by the time setting switch 11.

The operation of the time setting device configured as described above will be described below.

When the time of the internal clock 9 is wrong or when the initial setting is performed, the time setting switch 11 is manually set and the internal clock 9 operates based on the set time.

[0006]

However, in the conventional time setting device as described above, when the current time is set by the time setting switch 11, accurate current time information is obtained by telephone time signal or TV time signal. Since it is necessary to obtain it and manually operate the time setting switch 11 to set the time, the setting accuracy is poor, and when setting the time for a plurality of devices, it is necessary to set one by one. Therefore, there is a problem that it takes a lot of time and labor.

In particular, in recent years, there have been an extremely large number of electric devices having a clock function, such as VTRs, televisions, stereos, computers, etc. in homes, stores, offices, etc., and it is extremely difficult to perform accurate time setting operations for all of them. It was complicated.

The present invention solves the above-mentioned conventional problems and eliminates the trouble of obtaining accurate current time information and the trouble of manually operating the time setting switch. An object of the present invention is to provide an automatic time setting device that can set the time manually.

[0009]

In order to achieve the above object, the present invention comprises a time signal receiving section and an internal timepiece which is automatically corrected based on the time signal received by the time signal receiving section. An automatic time setting device for transmitting the time signal to an external device, a receiving section for receiving a signal including time information, a time information detecting means for detecting time information from the received signal, and the time A time signal transmitting section for transmitting a time signal to the time signal receiving section based on information is provided.

[0010]

According to the present invention, the time signal receiving section of the automatic time setting device receives the signal including the time information such as the TV signal of NHK by the above structure, and the accurate time information is detected from the received signal. The time signal transmitting unit transmits the time signal to an external device having an internal clock such as a VTR.

Further, the time signal receiving section provided in the external device receives the time signal transmitted from the time signal transmitting section and automatically corrects the display time of the internal clock.

By thus integrally including the automatic time setting device, the internal clocks of all external devices having the time signal receiving section are always set based on an accurate time signal.

[0013]

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 automatic time setting device of this embodiment. In FIG. 1, 1 is a receiving unit for receiving a television signal or the like including time information, 2 is a time signal detecting unit for detecting the received time signal, 3
Is an internal clock correction signal generator for correcting the time of the internal clock 4, 5 is a time initial setting switch for setting the initial time of the internal clock 4, and 6 is a time signal transmission for outputting the time information of the internal clock 4. The section 7 is an automatic time setting device having the above configuration.

Reference numeral 10 denotes an external device, which has a time signal receiving unit 8 for receiving the time information transmitted from the time signal transmitting unit 6 therein and a time based on the time information received by the time signal receiving unit 8. An internal clock 9 for displaying is provided.

The external device 10 is, for example, a video tape recorder or an answering machine.

The operation of the automatic time setting device of this embodiment constructed as described above will be described below.

First, the current time is appropriately set by operating the time initial setting switch 5 on the internal clock 4 by the time signal of the telephone or the time signal of the television. After the internal clock 4 starts operating, the receiving unit 1 receives, for example, a TV radio wave NHK time signal for several minutes before and after at three timings of 7:00 am, noon, and 7:00 pm, and at each time, 440 Hz at 1 second intervals. When the time signal detection unit 2 detects a time signal that is emitted three times and the 880 Hz audio signal once, the internal clock correction signal generation unit 3 sends the time information to the internal clock 4, and the internal clock 4 clocks the TV signal. If there is an error with the NHK time signal, it will be corrected automatically.

Then, the time information of the internal clock 4 is input to the time signal transmitting unit 6, transmitted from the time signal transmitting unit 6 to the external device 10, and received by the time signal receiving unit 8. Input from the time signal receiving unit 8 to the internal clock 9 starts the operation of the internal clock 9.

As described above, according to this embodiment, by transmitting the time information from the time signal transmitting unit 6 of the automatic time setting device 7 to the external device 10, the internal clock 9 of the external device 10 is automatically and accurately set. It can be set to any time.

For example, a VTR provided in a general household, an AV device such as a television set, an answering machine, an alarm clock, an electric device having a time display function such as a personal computer, etc., is provided with a time signal receiving section, and one automatic time setting device 7 main body is provided. By providing the above in a home, it is possible to always set an accurate time, and it is extremely useful that a complicated operation of setting the time for each of the above devices is unnecessary.

Further, the time signal receiving section 8 can be easily realized by sharing the time signal receiving section 8 of the present embodiment with the remote operation signal receiving section of the remote control apparatus in a TV, VTR or the like having a remote control apparatus. Therefore, it is possible to provide an electric device that can be accurately set at low cost.

In each of the above embodiments, the received signal including the time information is the TV time signal NHK time signal, and the reception time is 7:00 am, noon, and 7:00 pm, but the invention is not limited to this.

[0024]

As described above, according to the present invention, since the time of the internal clock can be automatically corrected based on the time signal of the received signal, it is necessary to set the correct time by the time signal of the telephone or the time signal of the television. Moreover, since the accurate time information is output to all the external devices equipped with the time signal receiving means only by including this device integrally, if the device is equipped with the time signal receiving means, the time of all devices is collectively set. It also has a very beneficial effect of being set.
