Description

  The present invention relates to a digital display type radio-controlled timepiece.

In recent years, radio-controlled timepieces that receive radio waves including time information (long wave standard radio waves) and automatically correct and display the time with the time information have come to be used.
Such radio-controlled watches, especially wristwatch-type radio-controlled watches, have a relatively small antenna size and are often worn by users. Even if processing was performed, reception sometimes failed.

  For this reason, there is known a radio-controlled timepiece configured to be able to display a reception result indicating whether reception is successful or unsuccessful by a button operation or the like (see, for example, Patent Document 1).

JP 2002-372592 A

However, in the radio-controlled timepiece of Patent Document 1, since the reception result (successful reception or reception failure) and the reception time are displayed in association with each other, the reception situation can be estimated to some extent, but the exact reason for the reception failure can be grasped Rather, there was a problem that the user could not grasp the reason why the message could not be received.
In addition, in the radio-controlled timepiece disclosed in Patent Document 1, when forced reception is instructed or reception processing is performed when a preset automatic reception time is reached, there is a high possibility that reception will fail. However, there is also a problem that reception processing is performed and wasteful power consumption is performed.

  An object of the present invention is to provide a radio-controlled timepiece that can reduce useless reception processing and can easily grasp the reason why a user was unable to receive.

  The present invention includes a receiving means for receiving radio waves including time information, a digital display means, a control means for controlling the driving of the receiving means and the display means, and a reception prohibiting condition for prohibiting reception processing by the receiving means. Storing means for storing the operation, and the control means determines an operation detecting means for detecting an operation state of the timepiece and whether or not the operation state detected by the operation detection means corresponds to the reception prohibition condition. A prohibition condition determination means, a reception prohibition means for prohibiting reception processing by the reception means when the prohibition condition determination means determines that the reception prohibition condition is satisfied, and a reason for prohibiting the reception processing on the display means Receiving prohibition reason display means.

According to the present invention, the reception prohibition condition is stored in the storage unit in advance, and when the operation state detected by the operation detection unit corresponds to the reception prohibition condition, the reception control unit prohibits the reception process. Can be prevented.
In addition, when the reception process is prohibited, the reason why the reception is not performed is displayed by the reception prohibition reason display means, so that the reason why the user could not receive can be easily grasped. For this reason, by grasping the reason for prohibition of reception, for example, the user can perform reception processing by eliminating a state that hinders reception processing, and can improve the probability of successful reception processing.

  In the present invention, the storage means stores a reception interruption condition for interrupting reception processing by the reception means, and the control means determines whether the operation state detected by the operation detection means corresponds to the reception interruption condition. Interruption condition determination means for determining whether or not, a reception interruption means for interrupting reception processing by the reception means when the interruption condition determination means determines that the reception interruption condition is satisfied, and reception processing is interrupted by the display means It is preferable to provide reception interruption reason display means for displaying the reason for the failure.

According to the present invention, the reception interruption condition is stored in the storage means in advance, and if the operation state detected by the operation detection means corresponds to the reception interruption condition, the reception control means interrupts the reception process, It is possible to prevent the continuous reception process from being continued.
When the reception process is interrupted, the reason for interrupting reception is displayed by the reception interrupt reason display means, so that the user can easily grasp the reason for interrupting reception. For this reason, by grasping the reason for interruption of reception, the user can perform the reception process by eliminating the situation where the reception process is interrupted, for example, and can improve the probability that the reception process is successful.

  In the present invention, it is preferable that the control unit includes a reception result determination unit that determines a reception result indicating whether the reception has succeeded or failed, and a reception result display unit that displays the reception result on the display unit.

  According to the present invention, the reception result can be determined by the reception result determination unit, and the result can be displayed by the reception result display unit, so that the user can easily grasp the reception result. For this reason, by grasping the reception result, the user eliminates the reason for the reception failure, such as placing a clock in a place suitable for reception processing such as by the window in the room when the previous reception failed. It is possible to take measures that can be performed, and to improve the probability of successful reception processing.

  Here, the control unit includes a time display city selection unit that allows a time to be displayed on the display unit to be selected from a plurality of cities or regions, and the operation detection unit is a city selected by the time display city selection unit. Alternatively, the area is configured to be detectable, and the reception prohibition condition is set to a condition for prohibiting reception processing when the selected city or area is a city or area that cannot receive radio waves including time information, The reception prohibition reason display means is preferably configured to be able to display that the selected city or region is a city or region incapable of receiving radio waves including time information as a reception processing prohibition reason.

  According to the present invention, when a city where radio waves cannot be received is selected as a time display target, reception processing can be prohibited, so that the city has originally moved to a city where radio waves cannot be received. When the time is set to be displayed, useless radio wave reception processing can be prevented.

  Here, the control means includes an additional function control means for executing a timer function or a stopwatch function, and the operation detection means is configured to be able to detect that the timer function or the stopwatch function is operating, In the reception prohibition condition, a condition for prohibiting reception processing is set while the timer function is operating or the stopwatch function is operating, and the reception prohibition reason display means sets the reception processing prohibition reason as the timer function operating or stopwatch. It is preferable to be able to display that the function is being operated.

  According to the present invention, since reception is prohibited while the timer function or the stopwatch function is operating, it is possible to prevent the radio wave reception process and the timer or stopwatch function operation process from being executed simultaneously. For this reason, it is not necessary to use a high-performance IC that can process radio wave reception and a timer or stopwatch function at the same time and that consumes a large amount of power as an IC that controls the operation of the watch. In addition, a low-cost radio-controlled timepiece can be provided because of low power consumption and long battery life.

  Here, the control means includes an alarm control means for notifying an alarm when a set alarm time is reached, the action detecting means is configured to detect the alarm action, and the reception interruption condition includes a radio wave reception condition. If an alarm is activated during the operation, a condition for interrupting the reception process is set, and the reception interruption reason display means displays that the alarm is being activated or the alarm has been activated as the reason for interrupting the reception process. It is preferable that the configuration is possible.

  According to the present invention, when an alarm is activated even during radio wave reception, the reception process is interrupted and the alarm operation is performed. Therefore, the alarm operation affects radio wave reception and fails to receive the radio wave. This can be prevented beforehand. That is, since an alarm is sounded using, for example, an electromagnetic coil, there is a high possibility that reception will fail even if radio wave reception continues due to the electromagnetic field generated from the coil affecting radio wave reception. On the other hand, in the present invention, when the alarm is activated, the radio wave reception is interrupted, so that it is possible to prevent the reception process from failing due to the alarm operation. Since the alarm operation is prioritized over the radio wave reception process, it is possible to reliably notify that the set alarm time has been reached.

  Here, the operation detection means is configured to be able to detect a button operation of a watch, and the reception interruption condition is set to a condition for interrupting reception processing when the button is operated during radio wave reception, The reception interruption reason display means is preferably configured to be able to display that the button operation has been performed as the reception processing interruption reason.

  According to the present invention, when the button operation of the watch is performed, the reception process is interrupted even when the radio wave is being received, so that the button operation affects reception and the radio wave reception fails. It can be prevented beforehand. That is, when the button is operated, the posture of the timepiece is often changed or the timepiece is moved, which increases the possibility of failure in radio wave reception. On the other hand, in the present invention, reception of radio waves is interrupted when a button operation is performed, so that it is possible to prevent a reception process from failing due to the button operation. In addition, since the button operation is prioritized over the radio wave reception process, the user's operation can be surely executed.

  Here, when the prohibition condition determination means determines that the reception prohibition condition is satisfied, the control means displays on the display means that the reception prohibition state is displayed until the reception prohibition condition is resolved. It is preferable to provide a display means.

  According to the present invention, since the user can easily grasp that the reception is prohibited, it is possible to prevent performing a useless forced reception operation, and the user performs the reception operation while always grasping the receivable state. And the possibility of successful reception can be improved.

  Here, it is preferable that the reception prohibition reason display means displays the reception prohibition reason on the display means in accordance with a user operation.

  Since the reception prohibition reason can be displayed by the user's operation, when the receiver wants to check the reason why the reception was not possible, it can be easily confirmed, and the radio-controlled timepiece can be easily used.

  As described above, according to the radio-controlled timepiece of the present invention, useless reception processing can be reduced, and the reason why the user has failed to receive can be easily grasped.

  After 10 seconds have elapsed from the reception result display of FIG. 6 or when the C button 33 is pressed, the display control means 44 returns the display of the display means 6 to the original home time (time / calendar) mode.

As shown in FIG. 4, when the prohibition condition determination unit 421 determines that the reception prohibition condition is satisfied, the reception prohibition reason display unit 441 displays the reception prohibition reason on the display unit 6.
9 to 11 exemplify the reason for prohibition of reception displayed on the display means 6.
In other words, in this embodiment, (I) the city other than the city where the home city setting is determined (for example, Tokyo, Seoul, Hong Kong), (II) the stopwatch is operating, (III) the timer is operating If (IV) I and II overlap, (V) I and III overlap, (VI) II and III overlap, (VII) I, II and III Seven types of reception prohibition conditions are set in the case of duplication, and if any of the reception prohibition conditions is met, the reception prohibition means 431 does not execute reception processing even if a forced reception operation is performed, The prohibition reason display means 441 displays the reception prohibition reason.

For example, when the condition I is satisfied, as shown in FIG. 9A, the reception prohibition reason display unit 441 displays the characters “CHECK” and “CITY” on the first display unit 61 by switching them at intervals of 1 second. Then, the user is notified that the home city setting is other than a predetermined city.
Specifically, the radio-controlled timepiece 1 of this embodiment is a radio-controlled timepiece that can receive Japanese longwave standard radio waves JJY, and Seoul (Korea) and Hong Kong are areas that can receive longwave standard radio waves JJY. Since the time of the city can be correctly displayed by adding the time difference to the time information of this long wave standard radio wave JJY, reception processing is performed when not only Tokyo (Japan) but also Seoul or Hong Kong is selected as the home city. I am doing so. On the other hand, when a city other than these cities is selected as the home city, since the radio wave that can be received by the radio-controlled timepiece 1 cannot be received in that city, the reception prohibition unit 431 prohibits the reception process and displays the reception prohibition reason display unit. Reference numeral 441 displays on the display means 6 that reception is prohibited due to the setting of the home city.

When the condition II is satisfied, as shown in FIG. 9B, the reception prohibition reason display unit 441 displays “CHECK” on the first display unit 61 and “STP.W” on the third display unit 63. ”Is lit, and the user is notified that reception processing is prohibited because the stopwatch is operating.
Further, when the condition III is satisfied, the reception prohibition reason display unit 441 displays “CHECK” on the first display unit 61 and “TMR” on the third display unit 63 as shown in FIG. 9C. The indicated icon 635 is turned on to notify the user that the reception process is prohibited because the timer is operating.

Further, when the condition IV or the condition V is satisfied, as shown in FIGS. 10D and 10E, the reception prohibition reason display unit 441 displays the notification in the case of the condition I and the case of the condition II or III. By performing both the notification and the notification, it is notified that the reception process is prohibited because the two conditions are satisfied.
Further, when the condition VI is satisfied, as shown in FIG. 11 (F), the reception prohibition reason display means 441 performs both the notification in the case of the condition II and the notification in the case of the condition III, thereby Notify that the reception process is prohibited because the two conditions are met.
Further, when the condition VII is satisfied, as shown in FIG. 11G, the reception prohibition reason display unit 441 performs all the notifications in the case of the conditions I to III so that the three conditions are satisfied. Is notified that reception processing is prohibited.

Further, the reception prohibiting unit 431 stores the date and time when the reception process is prohibited and the reason for the reception prohibition in the storage unit 5 as a reception history.
Then, after 10 seconds have elapsed from the reception prohibition reason display in FIGS. 9 to 11 or when the C button 33 is pressed, the display control means 44 changes the display on the display means 6 to the original home time (time / calendar) mode. return.

(Automatic reception display)
On the other hand, the radio-controlled timepiece 1 also has a function of performing automatic reception processing for automatically receiving radio waves when a preset time is reached. That is, when the internal time measured in the radio-controlled timepiece 1 reaches a preset reception time, the reception control unit 43 performs automatic reception by the prohibition condition determination unit 421 as shown in FIG. Judgment is made whether or not the condition is met. Specifically, the prohibition condition determination unit 421 determines whether or not various operation states detected by the operation detection unit 41 correspond to a reception prohibition condition.
Then, the reception prohibiting means 431 receives the reception prohibiting conditions at the time of automatic reception, specifically, the conditions shown in FIG. 12A, that is, “(1) Home time (time / calendar) mode or other than the world time mode” , (2) When the time is corrected, or when the demo is being displayed (while the character scroll is being displayed), and (3) When the reception prohibition conditions I to VII are met as in the case of forced reception, If this is true, automatic reception is not performed, and the time when the reception was not performed and the reason thereof are stored in the storage unit 5 as a reception history.

  When the reception prohibition condition is not satisfied, the display control unit 44 displays that the reception is being performed on the first display unit 61 as shown in FIG. When the buttons 31 to 34 are operated during reception, that is, when the interruption condition determination means 422 determines that the reception interruption condition is satisfied, the reception interruption means 432 of the reception control means 43 interrupts automatic reception. The time when the reception is interrupted and the reason thereof are stored in the storage means 5, and the mode (home time mode or world time mode) immediately before shifting to reception is restored.

When the reception process is completed, as shown in FIG. 13, whether or not the reception is successful is determined by the reception result determination unit 433 of the reception control unit 43 as in the case of the forced reception process. If reception is successful, the reception result display means 443 displays “OK” on the first display unit 61 and displays the reception icon 637 as a level icon as shown in FIG. Make sure that everything is lit.
On the other hand, if reception fails, the reception result display means 443 displays “ERROR” on the first display unit 61 and displays the reception icon 637 as shown in FIG. 13B. Set all the lights off.
The reception result determination unit 433 stores the date and time of reception processing and the result (success or failure) in the storage unit 5 as a reception history.

  After 10 seconds have elapsed from the reception result display of FIG. 13 or when the C button 33 is pressed, the display control means 44 returns the display of the display means 6 to the original home time (time / calendar) mode.

  Also, the reason display when the reception process fails in the automatic reception process is displayed by the user's button operation. That is, the automatic reception processing is usually set to be performed from midnight (for example, 2:00 am) to early morning (for example, 5:00 am) when the operation of other electronic devices is reduced and radio waves are easily received. Yes. For this reason, as shown in FIG. 12, even if the reason is displayed when the reception is not performed due to the reception prohibition condition at the time of the reception process, there is a high possibility that the user cannot confirm while sleeping. For this reason, in this embodiment, when the reception prohibition condition is satisfied in FIG. 12, the reason is not displayed immediately as in the case of forced reception, but is displayed when the user performs a confirmation operation. ing.

  That is, when the C button 33 is pressed in the normal home time (time / calendar) mode, “RECEIVE” is displayed on the first display unit 61 as shown in FIG. To do. When 1 second to 2 seconds elapse, the reception result display unit 443 refers to the past reception history stored in the storage unit 5 and, as shown in FIG. The date and time when the reception was successful recently is displayed on the display means 6.

Then, after 10 seconds have elapsed from the display of FIG. 14B or when the C button 33 is pressed, the display control means 44 displays “ERROR” on the first display section 61 as shown in FIG. 14C. Then, an error code (“1” in FIG. 14C) is displayed in the second display portion of the second display section 62.
Subsequently, the display control means 44 refers to the past reception history stored in the storage means 5 as shown in FIG. 14 (D) after 1 second to 2 seconds have elapsed after the display in FIG. 14 (C). The date and time when reception failed recently is displayed on the display means 6.
The reception failure includes a case where the reception process is performed but the reception is prohibited, a case where reception is prohibited, and a case where reception is interrupted. The prohibition reason display unit 441, the reception interruption reason display unit 442, and the reception result display unit 443 appropriately display the error code and the reception failure date and time.
Then, after 10 seconds have elapsed from the display of FIG. 14D or when the C button 33 is pressed, the home time (time / calendar) mode is restored.

The error code displayed in FIG. 14C is, for example, (1) when trying to receive a radio wave but cannot receive it, “ERROR 1: radio wave condition was bad”, (2) radio wave reception Is ERROR 2: When the home city is set in a city / region where standard radio waves do not reach, “ERROR 3: Timer function is operating”, “ERROR 4: Stopwatch function is operating” ”Medium”, (3) When radio wave reception is interrupted, “ERROR 5: The alarm time was reached during radio wave reception, so the radio wave reception was interrupted and the alarm sounded”, “ERROR 6: Light during radio wave reception, etc. Because there was a button operation, the radio wave reception was interrupted and processing corresponding to the button operation such as lighting of the light was performed. ”
When there are a plurality of reasons, for example, a plurality of codes are displayed as “ERROR: 2, 3”.
Further, the meaning of each code may be described in a section such as “examine the reason for reception failure” in the instruction manual of the radio-controlled timepiece 1 so that the user can confirm it.

According to such 1st Embodiment, there can exist the following effects.
(1) When performing the forced reception process and the automatic reception process, the reception control unit 43 first checks whether or not the reception prohibition condition is satisfied by the prohibition condition determination unit 421, and if the reception prohibition condition is satisfied. Since the reception prohibiting means 431 controls so that the reception processing itself is not performed, it is possible to eliminate the possibility of the reception processing being wasted when the radio-controlled timepiece 1 is highly likely to fail to receive. . For this reason, useless power consumption can be eliminated.

(2) Furthermore, since the reception prohibition reason display means 441 is configured so that the reason for the reception failure can be displayed and notified to the user, the user can accurately grasp the reason for the reception failure. For this reason, since the user does not know the reason why the reception is not possible, the user can be prevented from misunderstanding that the timepiece 1 is out of order or becoming uneasy. In addition, for example, there may be no forced operation when a city that cannot receive radio waves is set as a home town, or when a forced reception operation is performed while the stopwatch function or timer function is active. it can.
Therefore, it is possible to provide the radio-controlled timepiece 1 that is excellent in user interface and easy to use.

(3) The reception prohibition reason display means 441 displays each reason in an easy-to-understand manner using the first display unit 61, icons 631 to 635, etc. when displaying the reason for reception failure. The reason why the reception is not performed intuitively can be grasped, and the radio-controlled timepiece 1 that is easy to use can be obtained in this respect.

(4) Furthermore, the interruption condition determination means 422, the reception interruption means 432, and the reception interruption reason display means 442 are provided, and if it is better to interrupt reception even during reception processing, the reception processing is performed. Since the interruption is made possible and the reason can be displayed, it is possible to prevent the continuation of useless reception processing, and the user can grasp the reason for the interruption, so that measures can be taken easily.
That is, when the buttons 31 to 34 are operated, since the posture of the timepiece 1 is not stable, the direction of the antenna is changed, and the possibility of failure in reception increases. Also, since alarms are often sounded using an electromagnetic coil or the like, there is a high possibility that radio wave reception will fail due to the influence of an electromagnetic field generated from the coil during alarm driving. Therefore, it is possible to prevent useless reception processing from being continued by interrupting radio wave reception when these operation states are detected.

(5) Further, in the home time mode, since the reception history can be displayed by the user pressing the C button 33, the user can easily grasp the contents when he / she wants to check the reception history. Therefore, it is possible to easily take measures suitable for future reception.

[Second Embodiment]
Next, a second embodiment of the present invention will be described.
As shown in FIG. 15, in the second embodiment, in addition to the configuration of the first embodiment, when the radio-controlled timepiece 1 is in the reception-inhibited state, the display means 6 displays the reception-inhibited mode. The reception prohibit mode display means 444 is added to the display control means 44.

  What is displayed on the display means 6 by the reception inhibition mode display means 444 is, for example, an icon 64 as shown in FIG. The icon 64 has a shape in which an antenna is imaged and an oblique bar that images the prohibition of use of the antenna is overlapped, and the user can easily recall that reception is prohibited.

  In such a second embodiment, the reception prohibition mode display unit 444 displays the state corresponding to the reception prohibition condition by the prohibition condition determination unit 421, for example, when the home town setting is set to a city other than the receivable city, When the timer function is in operation, the icon 64 is displayed (lighted) on the display means 6, and when the reception prohibition condition is not met, for example, when the home town setting is set as a receivable city, When the operation of the watch or timer function ends, the icon 64 is turned off.

  In this embodiment, the same function and effect as the first embodiment can be achieved, and the icon 64 is lit on the display means 6 when the radio-controlled timepiece 1 is in a reception-inhibited state. Therefore, the user can easily determine whether the reception is currently prohibited before performing the forced reception operation. For this reason, for example, it is possible to confirm and change the setting of the home town, or to terminate the stopwatch or timer function and perform the forced reception process after the icon 64 is turned off. For this reason, when the forced reception operation is performed, it is possible to prevent a state in which reception is not possible due to the reception prohibition condition, and it is possible to make the radio-controlled timepiece 1 more convenient for the user.

[Third Embodiment]
Next, a third embodiment of the present invention will be described.
In this embodiment, the reception prohibition reason display means 441 displays an error code as the display performed when the reception prohibition condition is met during the forced reception operation, as in the automatic reception.
Even in such a configuration, the same operational effects as those of the first embodiment can be obtained. In addition, since only simple characters and codes can be used for error display, it is possible to display even types that can only display simple characters and numbers, such as when a segment type liquid crystal display device is used as the display means 6. Cost can be reduced.

Next, a fourth embodiment of the present invention will be described.
In the present embodiment, as shown in FIGS. 17 to 20, as a method of displaying the reception result on the display unit 6, the reason for the reception failure is displayed in characters. Specifically, the reception result and failure reason are displayed in characters of each language selected by the user such as Japanese or English.
At this time, as the display means 6, a so-called electronic paper such as an electrophoretic display device, an organic EL device, a liquid crystal display device, or a device capable of high-definition image display called a flexible display is used.

According to such an embodiment, the same operational effects as the above embodiment can be obtained, and various information can be displayed in characters, so that the reason for reception failure can be displayed more clearly, and the user can easily confirm it. it can.
The radio-controlled timepiece 1 shown in FIGS. 17 to 20 is a timepiece configured in a ring shape, and is used by being worn like a bracelet on a wrist. The present embodiment can also be applied when using a display device such as paper.

It should be noted that the present invention is not limited to the above-described embodiment, and modifications, improvements, and the like within a scope that can achieve the object of the present invention are included in the present invention.
For example, in the above embodiment, when the reception process is prohibited due to the reception prohibition condition at the time of automatic reception, the reason for the reception prohibition has not been displayed. May be displayed. However, during automatic reception processing, it is often set to be performed by the user while sleeping, so there is a high possibility that the user has not confirmed it even if it is displayed. It is preferable that the display is performed during the operation in that the power consumption can be reduced.

In the first embodiment, when the automatic reception result is displayed, the reason for the reception failure is displayed as a code as shown in FIG. 14C. However, as in the forced reception shown in FIGS. Alternatively, characters and icons may be used for display.
Conversely, code display as shown in FIG. 14 may be used to display the result of forced reception.

The reception prohibition condition is not limited to the above embodiment, and may be set as appropriate according to the specifications of the timepiece 1. For example, if the radio wave correction watch 1 is a watch that can receive radio waves not only in Japan (JJY) but also in the UK (MSF), USA (WWVB), Germany (DCF77), etc. Cities / regions that can be set by radio wave reception may be removed from the reception-prohibited targets when setting the home town.
In addition, when an IC capable of simultaneously processing radio wave reception and the stopwatch function or timer function is used, the stopwatch or timer driving condition may be removed from the reception prohibition condition. In short, as the reception prohibition condition, it is only necessary to set a condition for prohibiting reception when at least a city / region where radio waves cannot be received is set as a home town. What is necessary is just to set suitably according to.

The reception prohibition condition and the reception interruption condition are not limited to those described in the above embodiment, and may be set as appropriate based on the function of the radio-controlled timepiece 1 or the like.
Furthermore, the display of the reception history is not limited to that displayed only on the display means 6 of the radio-controlled timepiece 1, and data is transmitted wirelessly or by wire to other devices, for example, external devices such as mobile phones and personal computers. May be displayed. If such an external device can be displayed, a more detailed reception history can be displayed, and the user can grasp the reception status in more detail. Further, the reception prohibition condition and the reception interruption condition may be configured to be editable by a user or the like.

Each means of the control means 4 is configured such that a computer having a CPU (central processing unit), a memory (storage device) and the like is provided in the radio-controlled timepiece 1, and a predetermined program is incorporated in the computer to realize each means. The configuration is not limited to that, and hardware such as various logic elements may be used.
However, a CPU and a memory are arranged in the radio-controlled timepiece 1 so as to function as a computer, and a predetermined control program and data are recorded in the memory such as communication means such as the Internet, CD-ROM, memory card, etc. When each means of the control means 4 is realized by installing the program via a medium and operating a CPU or the like with the installed program, various functions can be realized only by changing the program. The control program desired by the user can be selected and incorporated. In this case, since various radio-controlled timepieces 1 having different control formats can be manufactured only by changing the program, the parts can be shared, and the manufacturing cost when developing variations can be greatly reduced.
In order to install a predetermined program or the like in the radio-controlled timepiece 1, a memory card, a CD-ROM or the like may be directly inserted into the radio-controlled timepiece 1, or an external device for reading these storage media may be used. May be connected to the radio-controlled timepiece 1.
