Description of the Related Art Currently, in Japan, under the jurisdiction of the Ministry of Posts and Telecommunications, standard radio waves with time information superimposed are transmitted on a trial basis, and there is a plan to begin full-scale transmission of time information by radio waves in the near future. , There is an increasing demand for clocks that use this radio wave to correct the time. In the United States and Germany, radio waves with time information superimposed are transmitted, and watches that receive this radio wave and correct the time are commercially available. In each country, the transmission format of time information is one frame for one minute, in which "minute", "hour", "day", "day of the week", "month", "year"
The value such as 1 is pulse-modulated by BCD code (Binary-Coded Decimal code) at 1 Hz and sent, and the leading or trailing edge of the leading pulse of one frame is 0 correctly.
Synchronized to seconds. A conventional radio-controlled timepiece takes in one-frame or several-frame time information from the time when the 0-second signal is first received from the start of radio wave reception, and corrects the time.

Information such as "day" is divided into groups, and "1" and "0" are distinguished by changing the pulse width.
The "day" information is shown as the total date from January 1st. The pulse rises every 1 second and the pulse width is 500m.
In the case of s, "1" is shown, in the case of 800 ms, "0" is shown, and in the case of 200 ms, the group of information such as "minute", "hour", "day", and the frame are shown. The weighting of each pulse is predetermined, and in the case of the time information of FIG. 2, it shows 18:42 on 253rd.
In addition, the pulse width is 2 for the first and last 1 second of one frame.
It is set to 00 ms. That is, the pulse width is 200 ms
The second rising edge of the pulse when the signal of 2 continues for 2 times indicates 0 second. The rising edge of this second pulse is 0
It becomes second information.

After the power is turned on and the counter 5 is reset, reception of a radio wave including time information is started (step A).

This fetching is carried out serially from the first rising edge of the received time information signal, and the number of bits of the information is counted by the counter 5. When the 0-second information detecting means 6 detects the 0-second information, the reception control means 7 determines the number of bits of the time information to be subsequently received according to the count value of the counter 5 at that time.

First, the first 1 bit of the frame is 0 second information, and from this 0 second information, 8 bits are "minute" information, then 7 bits are continued at intervals of 3 bits, and then 3 more information. The following 12 bits at intervals of bits include "day" information, and the following 26 bits include other information.

“日”の情報を完全に得られるのである（ステップ
Ｂ）。If the count value of the counter 5 is "38" or less when the 0 second information is detected, it means that none of the "minute", "hour" and "day" information has been completely fetched. When 33 bits of time information has been fetched after the second information, the reception control means 7 stops the energization of the reception means 3 and ends the reception operation. That is, if time information of 33 bits is fetched from 0 second information, "minute""hour"
The "day" information is completely obtained (step B).

憶されているのである。The time information fetching means 4 includes, for example, a register for storing information of 60 bits, and when the time information is fetched over 60 bits, the stored time information is sequentially rewritten from the beginning. For example, as shown in Figure 2,
When reception starts from point A in the frame, 67-bit time information up to point B in the next frame is fetched. The 7-bit information from the start of fetching is rewritten to the last 7-bit information. To be That is, when the time information acquisition is completed, the time information acquisition means 4 stores 60-bit information from B to B of the next frame.

The power supply to the means 2 is stopped and the reception operation is ended. That is, the count value of the counter 5 is "3.
If it is 9 "or more and" 48 "or less, it means that only the" day "information is completely captured, but the" minute "and" hour "information is not captured.
If the time information of 8 bits is taken in, the information of "minute" and "hour" can be completely obtained (step C).

The power supply to the means 3 is stopped and the reception operation is ended. That is, the count value of the counter 5 is "4.
If it is 9 "or more and" 59 "or less, it means that the information of" hour "and" day "is completely captured but the information of" minute "is not captured. By capturing the time information, the "minute" information can be obtained completely (step D).

Since it means that all the information of "day" is completely taken in, the reception control means 7 causes the reception means 3 at this point.
To stop receiving power and terminate the reception operation.

９で計時手段１の計時時刻を修正する。When the reception of the time information is completed as described above, the time calculating means 8 calculates the current time from the fetched time information, and the time adjusting means 9 determines the time measured by the time measuring means 1 based on the calculated current time. Fix it.
【００２４】ここで、時刻算出手段８による現在時刻の
算出動作について説明する。Now, the operation of calculating the current time by the time calculating means 8 will be described.

に１分を加算して時刻修正手段９に供給する。First, when "day" information is fetched before 0 second information and "minute" and "hour" information are fetched after 0 second information, if "hour" and "minute" are 00:00: , It means that the date has changed when the 0 second information was taken in,
Time information is obtained by advancing the "day" information by one day and connecting it to the "hour" and "minute" information. Then, 1 minute is added to the time information and the time information is supplied to the time adjustment means 9.
【００２６】また、０秒情報の前に“時”と“日”の情

に１分を加算して時刻修正手段９に供給する。When "hour" and "day" information is fetched before 0 second information and "minute" information is fetched after 0 second information, if "minute" is 00 minute, 0 Since the "hour" has been raised when the second information was captured,
The time information is obtained by advancing the "hour" information by one hour and connecting it to the "day" and "minute" information. In addition, when it is 0:00 when the "hour" information is advanced, the "day" information is further advanced by one day. One minute is added to the time information obtained in this way and supplied to the time adjustment means 9.
【００２７】なお、上記のような繰上げがない場合は、

However, the reception of the radio wave is not limited to this. It is also possible to fetch the time information for one frame from the time when the delimiter information indicating the time unit delimiter such as “minute” or “hour” is first received.
