The display unit 6 is configured by a liquid crystal display or the like, and displays a time and a message from the control unit 4.

In the present embodiment, various functions relating to the clock in the receiving apparatus are realized mainly by the control unit 4 shown in FIG. FIG. 1 is a functional block diagram showing a configuration example of various functions relating to the clock realized by the control unit 4. In addition to the function indicating the current time, the current time differs from the current time by a time set by the user. It also has a function to indicate the time.

In FIG. 1, a clock 41 includes a real time storage unit 411 for storing the current time, a timer 412 for generating a pulse every time a predetermined time elapses, and a real time storage for each time the timer 412 generates a pulse. An adder 413 adds a fixed time to the time (actual time) stored in the unit 411, and operates as a clock that outputs the current time. An updating unit 42 is connected to the real time storage unit 411. The updating unit 42 is configured to update the real time storage unit 411 based on real time information indicating the current time transmitted from the base station.
Is updated to the correct current time.

The real time storage unit 411 is connected to the input side of the correction unit 44, and the registration unit 43 is connected to the other input side of the correction unit 44. The registration unit 43 stores the correction time output from the key input unit 5, and the correction unit 44

These contents are connected to the display unit 6, and these contents can be selected and displayed on the display unit 6 by a key operation of the key input unit 5.

Next, the operation of the timepiece according to the present embodiment will be described with reference to FIGS. Here, FIG. 3 is a flowchart showing a procedure for updating the real time in the real time storage unit 411 and the correction time in the correction time storage unit 45 when real time information is received from the base station of the system. FIG. 4 is a flowchart showing a procedure for updating the real time in the real time storage unit 411 and the correction time in the correction time storage unit 45 when the real time information is not transmitted from the base station of the system.

First, the operation of this embodiment when real-time information is received from a base station of the system will be described with reference to FIGS. The base station of the system periodically or irregularly transmits real time information indicating an accurate current time to each receiving device. The receiving device shown in FIG. 2 receives the real time information transmitted from the base station by the antenna 1 and inputs the real time information to the control unit 4 via the receiver 2 and the decoder 3. In the control unit 4, the received real time information is input to the update unit 42 shown in FIG.

The update unit 42 updates the real time stored in the real time storage unit 411 with the time indicated by the real time information (FIG. 3, step 1). For example, when the real time information indicating 20:00 is received when the real time in the real time storage unit 411 is 19:55, the updating unit 42 stores the real time in the real time storage unit 411 in the real time storage unit 411. Update from 15:00 to 20:00. This allows
The real time in the real time storage unit 411 is updated to the exact current time indicated by the real time information every time the real time information is received. The real time in the real time storage unit 411 can be displayed on the display unit 6 by operating a key on the key input unit 5.

On the other hand, the user sets the key input unit 5 in advance.
Is operated while confirming the correction time input to the registration unit 43 displayed on the display unit 6,
To store the desired correction time. The correction unit 44 receives the real time output from the real time storage unit 411, generates a correction time by adding the correction time stored in the registration unit 43 to the real time, and corrects the correction time. The data is output to the time storage unit 45 (FIG. 3, step 2). The generated correction time is advanced by the correction time from the real time in the real time storage unit 411 when the correction time is positive, and delayed by the correction time when the correction time is negative. For example, when the real time from the real time storage unit 411 is 20:00 and the correction time stored in the registration unit 43 is +10 minutes, the correction time output from the correction unit 44 is 20:00. +10 minutes = 20:10, which is 10 minutes ahead of actual time.

The correction time storage unit 45 temporarily stores the correction time from the correction unit 44. The correction time in the correction time storage unit 45 can be displayed on the display unit 6 by operating the key of the key input unit 5 (FIG. 3, step 3). The above-described processes of steps 1 to 3 shown in FIG. 3 are executed every time real time information is received, and the correction time storage unit 45 is shifted from the real time in the real time storage unit 411 by the correction time. The correction time is stored. Therefore, the user can obtain a desired correction time shifted from the actual time by the correction time by changing the correction time stored in the registration unit 43. For example, when it is desired to know the local time in a foreign country, the correction time corresponding to the time difference may be stored in the registration unit 43.

Next, the operation of this embodiment when no real time information is transmitted from the base station of the system will be described with reference to FIGS.
This will be described with reference to FIGS. When the real-time information is not transmitted from the base station of the system, the receiving device shown in FIG. 2 does not receive the real-time information, and the real-time information is not input to the updating unit 42 in FIG. Therefore, the real time in the real time storage unit 411 of the clock 41 is not updated by the updating unit 42.

On the other hand, the timer 412 of the clock 41 always generates a pulse every time a predetermined time elapses, for example, every one minute, and outputs the pulse to the adder 413. Adder 413
Time data representing one minute is provided, and every time a pulse is received from the timer 412, one minute is added to the actual time stored in the actual time storage unit 411. Thus, the real time in the real time storage unit 411 is advanced by one minute every one minute (FIG. 4, step 1).

For example, if the real time in the real time storage unit 411 is 19
When a pulse is output from the timer 412 at 19:00, the adding unit 413 adds one minute to the real time in the real time storage unit 411, so that the real time in the real time storage unit 411 is 20:00. Updated at 00 minutes. Therefore, the real time storage unit 411 always holds the current time and operates as a normal clock. When the real time information is received from the base station, the updating unit 42 gives priority to the adding unit 413 to the real time storing unit 41.
Update the real time in 1.

The correction unit 44 receives the real time output from the real time storage unit 411 and generates a correction time by adding the correction time registered in the registration unit 43 to the real time. The time is output to the corrected time storage unit 45 (FIG. 4, step 2). The correction time storage unit 45 temporarily stores the correction time from the correction unit 44. The correction time in the correction time storage unit 45 can be displayed on the display unit 6 by a key operation of the key input unit 5 (FIG. 4, step 3). The processing of steps 1 to 3 shown in FIG. 4 described above is performed every time the real time in the real time storage unit 411 is updated by the adding unit 413.
That is, it is executed every one minute, and the correction time storage unit 45
The correction time that is always shifted by the correction time from the real time in the real time storage unit 411 is stored in the.

As described above, according to the present embodiment, the registration unit 43 for storing a correction time for correcting the current time.
And a correction unit 44 that generates a correction time shifted from the current time by the correction time is provided. By changing the correction time stored in the registration unit 43, a time shifted from the current time by a desired time is obtained. be able to.

In the present embodiment, one type of correction time is stored in the registration unit 43.
One correction time may be selected from the plurality of correction times by a key operation of the key input unit 5 and input to the correction unit 44. In this case, a plurality of types of correction times can be displayed on the display unit 6 by a key operation. This is convenient, for example, when you want to know the local time in a plurality of foreign countries.

In this embodiment, only the correction time is stored in the registration unit 43. However, together with the correction time, identification information indicating the correction time corrected by the correction time is also stored. It may be stored. In this case, the display unit 6 displays the correction time corrected by the correction time and the identification information corresponding to the correction time. With this identification information, it is possible to determine at a glance what time the correction time displayed on the display unit 6 is. This is particularly effective when a plurality of correction times are stored in the registration unit 43 and a plurality of correction times corresponding to the plurality of correction times are switched and viewed.

The display method by the display unit 6 is not particularly limited. The real time in the real time storage unit 411 and the correction time in the correction time storage unit 45 may be displayed on the display unit 6 at the same time. Alternatively, one of the times may be selected and displayed on the display unit 6 by operating the key of the key input unit.
