Further, during the positioning operation, the second hand 2c faces the positioning characters 5 and the positioning instruction member (first push button 60b), so that it can be visually grasped that the positioning operation is being performed. When an internal time correction operation to be described later is instructed, the time measurement character 6 is indicated by the second hand 2c, and it is possible to visually grasp which of the internal time correction operation and the positioning information determination operation is instructed.

  In this embodiment, the positioning character 5 and the first push button 60b are arranged in the 2 o'clock direction, and the time measuring character 6 and the second push button 60c are arranged in the 4 o'clock direction, so that the operation contents and instructions are provided. The members correspond to each other on a one-to-one basis, but other configurations may be employed. FIG. 6 is a plan view showing the appearance of a satellite radio-controlled wristwatch 1 according to a modification of the first embodiment of the present invention. In the modification, the positioning character 5 and the first push button 60b are arranged in the 2 o'clock direction, the second push button 60c is arranged in the 4 o'clock direction, and the timing character 6 is arranged in the 10 o'clock direction. . In the figure, the center line of the second push button 60c is represented by a one-dot chain line. In this modification, the time measurement character 6 is disposed on an extension line of the center line of the second push button 60c. Even in the case of adopting such a configuration, the time measurement character 6 and the second push button 60c are arranged on the extension line of the center line of the second push button 60c, so that the operation content, the indication member, and Correspond one-on-one, and the operation method can be intuitively grasped.

  That is, the second hand 2c, which is a pointer, faces away from the time adjustment instruction member (second push button 60c) with respect to the axis of the pointer when the time adjustment operation is displayed, and the positioning instruction member (the first indication member) when the positioning operation is displayed. You may face the push button 60b). Of course, the pointer may face the time adjustment instruction member when displaying the time adjustment operation, and may face the opposite of the positioning instruction member with respect to the axis of the pointer when displaying the positioning operation. Further, the pointer may be directed opposite to the time adjustment instruction member with respect to the axis of the pointer when displaying the time adjustment operation, and may be directed opposite to the positioning instruction member with respect to the axis of the pointer when displaying the positioning operation.

  Returning to FIG. 4, the processing after the reception circuit 20 starts receiving satellite radio waves will be described. While the satellite radio wave is being received, the second hand 2c does not move while pointing to the positioning character 5, and when the reception is completed at time t4, the second hand 2c performs positioning city display. The positioning city is the positioning information determined by the positioning information determination unit 313. The positioning information display unit 314 indicates the positioning city with the second hand 2c. For example, when the latitude and longitude of the current position determined by the positioning information determination unit 313 represent a position belonging to the UTC-5 time zone, the positioning information display unit 314 points to the third city 7c and displays the time of the current position. In addition to displaying the zone, it is displayed that the representative city of the time zone is New York. Note that the positioning information display unit 314 may also display daylight saving time information. Thereafter, at time t5, the second hand 2c returns to the normal time display.

  If the reception circuit 20 tries to receive the satellite radio wave for a certain period of time, but fails to receive the satellite radio wave, the reception failure character 4 may be indicated by the second hand 2c. By confirming the display of the reception failure character 4, it is possible to easily confirm that the reception of the satellite radio wave has failed and that the positioning information has not been determined.

  The time t3-t1 of the currently set city display performed between the time t1 and the time t3 and the time t5-t4 of the positioning city display performed between the time t4 and the time t5 are (t3-t1)> It is desirable that the relationship be (t5-t4). By adopting such a configuration, the user of the satellite radio-controlled wristwatch 1 can check the currently set city with a margin and can check the current time immediately after receiving the satellite radio wave.

  According to the satellite radio-controlled wristwatch 1 according to the present embodiment, positioning information including the time zone and city is displayed after the satellite radio wave is received, and the user has set the correct time zone after the time zone has been corrected. Can be confirmed. Further, the user can visually grasp whether or not the time zone has changed due to the positioning operation. Further, by using a pointer assigned to display a plurality of types of information such as the second hand 2c for displaying the positioning information, the positioning information can be shown to the user without providing a sub-needle dedicated to displaying the positioning operation.

  In the satellite radio-controlled wristwatch 1, the positioning information determination operation is instructed by a long press of the first push button 60b by the user, and the positioning information determination is performed by automatic reception such as so-called scheduled reception that starts reception at a predetermined time. An operation may be performed. In this case, since the user does not always visually recognize the dial 2, the positioning information display restriction unit 311 restricts the display of the positioning information by the positioning information display unit 314. In addition, the positioning information display unit 314 may limit operation display by the operation display unit 312, display of the reception result by the reception result display unit 316, and display of past display information by the past display information display unit 317. By adopting such a configuration, power consumption is reduced when automatic reception of satellite radio waves is performed.

  FIG. 7 is a flowchart showing positioning information determination operation in the satellite radio-controlled wristwatch 1 according to the first embodiment of the present invention. First, it is determined whether or not the first push button 60b (PB1) has been pressed (S1). If the first push button 60b is not pressed, the positioning information determination operation is not instructed, and the process ends.

  When the first push button 60b is pressed and the pressed state is maintained for a certain time and the time t1 has elapsed with reference to the time t0 (S2), the area information display unit 317d of the past display information display unit 317 By pointing to the first city 7a and the like with the second hand 2c, the currently set city as the regional information is displayed (S3). If the pressed state of the first push button 60b is not maintained for the time t1 (S2), it is determined whether or not the first push button 60b is pressed (S1). Ends and normal timekeeping is restored.

  Thereafter, when the pressed state of the first push button 60b is maintained for the time t2 (S4), the receiving circuit 20 is activated and preparations for tracking the satellite radio wave are made (S5). If the pressed state of the first push button 60b is not maintained for the time t2 (S4), it is determined whether or not the first push button 60b is pressed (S1). Ends and normal timekeeping is restored. Even if the first push button 60b is not pressed for the time t2 (S4) and the first push button 60b is not pressed (S1), the current city display is maintained until a predetermined time has elapsed. Then, it is possible to give the user time to confirm the currently set city and then return to the normal timing operation. In this case, the current set city display is maintained for a certain period of time longer than the time during which the positioning city display is performed (t5-t4), so that the currently set city can be confirmed with a margin and immediately after receiving the satellite radio wave. The current time can be confirmed. Further, even when the pressed state of the first push button 60b is not maintained for the time t2 (S4), the pressed state of the first push button 60b is released (S1), and the currently set city display is maintained, the operation unit It is also possible to return to the normal timing operation without waiting for the elapse of a certain time by the operation of 60 (for example, pressing the first push button 60b again).

  When the receiving circuit 20 is activated and only the time t3 has elapsed, the positioning operation display unit 312b displays the positioning operation by pointing the positioning character 5 with the second hand 2c (S6). Then, satellite radio waves are received by the receiving circuit 20 (S7).

  When the time t4 has elapsed and the reception of the satellite radio wave is finished, the positioning information display unit 314 indicates the first city 7a and the like by the second hand 2c, and includes the time zone included in the positioning information determined by the positioning information determination unit 313. Then, the city is displayed (S8). Thereafter, when the time t5 has elapsed, the second hand 2c returns to the normal time measuring operation, and the time is displayed (S9). While the time zone and the city are displayed (S8), the operation of the operation unit 60 (for example, pressing the first push button 60b again) returns to the normal timing operation without waiting for a certain period of time. It is good to do.

[Internal time adjustment]
FIG. 8 shows the second push button 60c (PB2), the receiving circuit 20 and the pointer (second hand 2c) when the satellite timepiece 1 according to the first embodiment of the present invention is instructed to perform an internal time adjustment operation. It is a figure which shows operation | movement along time. In the internal time adjustment operation, the internal time is corrected without correcting the time zone.

  In the satellite radio-controlled wristwatch 1 according to the present embodiment, when the second push button 60c is pressed at time t0 and is pressed for a long time until time t1, the previous reception result display unit 317a included in the past display information display unit 317 causes the previous time. The reception result is displayed. Specifically, the previous reception result is displayed by pointing the reception success character 3 or the reception failure character 4 with the second hand 2c. Thereby, the user of the satellite radio wave wristwatch 1 can know the success or failure of the previous reception prior to the reception of the satellite radio wave, and is used as a determination material for determining whether or not it is necessary to receive the satellite radio wave. Can do. The display of the previous reception result by the previous reception result display unit 317a may start from time t0 when the second push button 60c is pressed. In that case, the user of the satellite radio-controlled wristwatch 1 can check the previous reception result without waiting time.

  Here, when the reception failure character 4 is indicated by the second hand 2c in the internal time adjustment operation, one of the characters “NG” (for example, the character “G”) may be indicated. On the other hand, when the reception failure character 4 is indicated by the second hand 2c in the positioning information determining operation, the other character of the character “NG” (in this case, the character “N”) may be indicated. In this way, by changing the manner in which the reception failure character 4 is indicated by the positioning information determination operation and the internal time adjustment operation, the user of the satellite radio-controlled wristwatch 1 can easily determine in which operation the reception failure is being displayed. Can be confirmed.

  When the second push button 60c is pressed for a long time until time t2, the receiving circuit 20 is activated and preparations for tracking satellite radio waves begin. At this time, the operation instruction unit 310 instructs the internal time adjustment unit 315 to perform the internal time adjustment operation. In addition, the operation instruction unit 310 instructs the time adjustment operation display unit 312a to display the time adjustment operation.

  After the reception circuit 20 is activated, the reception circuit 20 starts receiving satellite radio waves from time t3. Here, the time adjustment operation display unit 312a displays that the internal time adjustment operation is being performed by moving the second hand 2c and pointing the time measurement character 6 prior to reception. Here, since the time measurement character 6 is arranged in the same direction as the time correction instruction member (second push button 60c), the second hand 2c faces the second push button 60c. In the case of the satellite radio-controlled wristwatch 1 shown in FIG. 1, the time measurement character 6 and the second push button 60c are arranged in the direction of 4 o'clock, and the time adjustment operation display unit 312a displays the second hand when displaying the time adjustment operation. Turn 2c to 4 o'clock.

  When displaying the time correction operation by the time correction operation display unit 312a, the center line of the second hand 2c does not necessarily need to coincide with the center line of the second push button 60c. The second hand 2c faces the second push button 60c means that the angle between the center line of the second hand 2c and the center line of the second push button 60c is the difference between the center line of the second hand 2c and the center line of the first push button 60b. It means smaller than the angle between.

  In the satellite radio-controlled wristwatch 1 according to this embodiment, the time measurement character 6 and the time adjustment instruction member (second push button 60c) for instructing the internal time adjustment operation are arranged in the same direction, and the operation method is intuitive. I can grasp. Further, during the internal time adjustment operation, the second hand 2c is directed toward the time measurement character 6 and the time adjustment instruction member (second push button 60c), so that the internal time adjustment operation is visually performed. I can grasp. In addition, it is possible to visually grasp which of the internal time correction operation and the positioning information determination operation is instructed.

  While the satellite radio wave is being received, the second hand 2c does not move while pointing the time measurement character 6, and when reception ends at time t4, the reception result display unit 316 displays the reception success character 3 or the reception failure character 4 The reception result is displayed by pointing with the second hand 2c. Thereafter, at time t5, the second hand 2c returns to the time display according to the internal time corrected by the internal time correction unit 315.

  Here, the time t3-t1 of the previous reception result display performed between the time t1 and the time t3 and the time t5-t4 of the reception result display performed between the time t4 and the time t5 are (t3-t1). > (T5-t4) is desirable. By adopting such a configuration, the user of the satellite radio wave wristwatch 1 can confirm the previous reception result with a sufficient margin, and can confirm the current time immediately after receiving the satellite radio wave.

  According to the satellite radio-controlled wristwatch 1 according to the present embodiment, the past display information displayed in the internal time adjustment operation is different from the information displayed in the positioning information determination operation, and indicates either the internal time correction operation or the positioning information determination operation. You can see visually.

  FIG. 9 is a flowchart showing an internal time adjustment operation in the satellite radio-controlled wristwatch 1 according to the first embodiment of the present invention. First, it is determined whether or not the second push button 60c (PB2) has been pressed (S40). If the second push button 60c is not pressed, the internal time adjustment operation is not instructed, and the process ends.

  When the second push button 60c is pressed and the pressed state is maintained for a certain time and the time t1 has elapsed with reference to the time t0 (S41), the past display information display unit 317 uses the second hand 2c to receive a successful reception character. The previous reception result is displayed by pointing to 3 etc. (S42). Note that if the pressed state of the second push button 60c is not maintained for the time t1 (S41), it is determined whether or not the second push button 60c is pressed (S40). Ends and normal timekeeping is restored.

  Thereafter, when the pressed state of the second push button 60c is maintained for the time t2 (S43), the receiving circuit 20 is activated and preparation for tracking of the satellite radio wave is made (S44). If the pressed state of the second push button 60c is not maintained for the time t2 (S43), it is determined whether or not the second push button 60c is pressed (S40). Ends and normal timekeeping is restored. Even when the second push button 60c is not pressed for the time t2 (S43) and the second push button 60c is not pressed (S40), the previous reception result is displayed until a predetermined time elapses. It is also possible to give the user time to confirm the previous reception result by maintaining it, and then return to the normal timing operation. In this case, the last reception result display is maintained longer than the time (t5-t4) during which the reception result display is performed, so that the previous reception result can be confirmed with a margin. The current time can be confirmed. Further, even when the second push button 60c is not pressed for the time t2 (S43), the second push button 60c is released (S40), and the previous reception result display is maintained, the operation unit It is also possible to return to the normal time measuring operation without waiting for the elapse of a certain time by the operation of 60 (for example, pressing the second push button 60c again).

  When the receiving circuit 20 is activated and the time t3 has elapsed, the time adjustment operation display unit 312a displays the time adjustment operation by pointing the time measurement character 6 with the second hand 2c (S45). The receiving circuit 20 receives satellite radio waves (S46).

  When the time t4 has elapsed and the reception of the satellite radio wave is completed, the reception result display unit 316 points to the reception success character 3 or the like with the second hand 2c and displays the reception result (S47). Thereafter, when the time t5 has elapsed, the second hand 2c returns to the normal timekeeping operation, and the time is displayed according to the internal time corrected by the internal time correction unit 315 (S48).

[Second Embodiment]
The satellite radio-controlled wristwatch 1 according to the second embodiment of the present invention is different from the satellite radio-controlled wristwatch according to the first embodiment regarding the positioning information determination operation, and the satellite timepiece wristwatch according to the first embodiment regarding the internal time correction operation. The same operation is performed. Therefore, the positioning information determination operation will be described below. FIG. 10 shows the first push button 60b (PB1), the receiving circuit 20 and the pointer (second hand 2c) when the positioning information determination operation is instructed to the satellite radio-controlled wristwatch 1 according to the second embodiment of the present invention. It is a figure which shows operation | movement along time. The positioning information determination operation in the satellite radio-controlled wristwatch 1 according to the second embodiment displays the amount of light applied to the receiving surface of the receiving unit (patch antenna) as additional information in the operation before receiving the satellite radio wave. This is different from the positioning information determination operation in the satellite radio-controlled wristwatch 1 according to the first embodiment. On the other hand, the operation after receiving the satellite radio wave is the same as that of the satellite radio wave wristwatch 1 according to the first embodiment. The physical configuration of the satellite radio-controlled wristwatch 1 according to the second embodiment is the same as that of the satellite radio-controlled wristwatch 1 according to the first embodiment.

  In the satellite radio-controlled wristwatch 1 according to the present embodiment, when the first push button 60b is pressed at time t0 and is pressed for a long time until time t1, the light amount display unit included in the additional information display unit 317b of the past display information display unit 317 is displayed. By 317c, information indicating the amount of light irradiated on the receiving surface of the receiving unit (patch antenna) is displayed. The detection of the amount of light may be performed based on the amount of power generated by the solar cell 43. Specifically, when it is determined that the amount of light is sufficiently large and the satellite radio wave can be received in an excellent environment, the second light amount display character 8b indicated as “HIGH” is indicated by the second hand 2c, and the amount of light is insufficient. When it is determined that it is difficult to receive satellite radio waves, the second light 2c indicates the first light quantity display character 8a represented as “LOW”. When the light quantity is intermediate, the second hand 2c points between the first light quantity display character 8a and the second light quantity display character 8b. Thereby, it is possible to show an index for determining whether or not the user of the satellite radio wave wristwatch 1 is in an environment where the radio wave intensity of the satellite radio wave is strong, and prompt the user to move to an environment where the radio wave intensity is strong. Can do. The display of the information indicating the light amount by the light amount display unit 317c may be started from time t0 when the first push button 60b is pressed. In that case, the user of the satellite radio-controlled wristwatch 1 can check an index for determining whether or not the user is in an environment where the radio wave intensity is strong without waiting time.

  When the long push of the first push button 60b is maintained until time t2, the operation instruction unit 310 instructs the positioning information determination operation, and the receiving circuit 20 is activated. Thereafter, at time t3, the region information display unit 317d of the past display information display unit 317 displays the currently set city as the region information by pointing to the first city 7a and the like with the second hand 2c. Since the display of the currently set city is maintained until time t4, the user can surely see the city set before the positioning operation is performed.

  Thereafter, at time t4, the positioning operation display unit 312b directs the second hand 2c to the positioning character 5 to display the positioning operation, and the reception circuit 20 receives the satellite radio wave. When the reception of the satellite radio wave is completed at time t5, the positioning information display unit 314 displays the positioning information determined by the positioning information determination unit 313, that is, the time zone and city name of the current position, the second hand 2c to the first city 7a, etc. Display by pointing. The positioning city display is maintained until time t6, and then the second hand 2c returns to the normal timekeeping operation, and the time display is performed.

  Here, the time t3-t1 of the light amount display performed between the time t1 and the time t3 and the time t6-t5 of the positioning city display performed between the time t5 and the time t6 are (t3-t1)> ( It is desirable that the relationship be t6-t5). By adopting such a configuration, the user of the satellite radio-controlled wristwatch 1 can determine whether or not the user is in an environment where the radio wave intensity is strong and can check the current time immediately after receiving the satellite radio wave.

  FIG. 11 is a flowchart showing positioning information determination operation in the satellite radio-controlled wristwatch 1 according to the second embodiment of the present invention. First, it is determined whether or not the first push button 60b (PB1) has been pressed (S20). If the first push button 60b is not pressed, the positioning information determination operation is not instructed, and the process ends.

  When the first push button 60b is pressed and the pressed state is maintained for a certain time and the time t1 has elapsed with reference to the time t0 (S21), the light amount display unit 317c included in the past display information display unit 317 is By pointing the second light quantity display character 8b and the like with the second hand 2c, the light quantity of light irradiated on the receiving surface of the receiving unit is displayed (S22). If the pressed state of the first push button 60b is not maintained for the time t1 (S21), it is determined whether or not the first push button 60b is pressed (S20). Ends and normal timekeeping is restored.

  Thereafter, when the pressed state of the first push button 60b is maintained for the time t2 (S23), the receiving circuit 20 is activated and preparations for tracking the satellite radio wave are made (S24). If the pressed state of the first push button 60b is not maintained for the time t2 (S23), it is determined whether or not the first push button 60b is pressed (S20). Ends and normal timekeeping is restored. Even when the first push button 60b is not pressed for the time t2 (S23) and the first push button 60b is not pressed (S20), the light amount display is maintained until a predetermined time elapses. It is also possible to give the user time to check the amount of light and then return to the normal timing operation. In this case, it is possible to determine whether or not there is an environment where the radio field intensity is strong with a margin by setting a certain time during which the light amount display is maintained to be longer than the time (t6-t5) during which the positioning city display is performed. The current time can be confirmed immediately after receiving the satellite radio wave. In addition, even when the pressing state of the first push button 60b is not maintained for the time t2 (S23), the pressing of the first push button 60b is released (S20), and the light amount display is maintained, An operation (for example, pressing the first push button 60b again) may return to a normal timing operation without waiting for a certain period of time.

  When the reception circuit 20 is activated and the time t3 has elapsed, the area information display unit 317d of the past display information display unit 317 displays the currently set city as the area information by pointing to the first city 7a and the like with the second hand 2c. (S25). Thereafter, when the time t4 has elapsed, the positioning operation display unit 312b displays the positioning operation by pointing the positioning character 5 with the second hand 2c (S26). The receiving circuit 20 receives satellite radio waves (S27).

  When the time t5 has elapsed and the reception of the satellite radio wave is completed, the positioning information display unit 314 indicates the first city 7a and the like with the second hand 2c, thereby including the time included in the positioning information determined by the positioning information determination unit 313. The zone and city are displayed (S28). Thereafter, when the time t6 has elapsed, the second hand 2c returns to the normal time measuring operation, and the time is displayed (S29).

  Note that the embodiments of the present invention are not limited to those described above. For example, in the above description, the positioning information is indicated by the second hand 2c, but the positioning information may be indicated by a pointer other than the second hand. Here, the pointer indicating the positioning information is assigned to display other information during the normal operation of the satellite radio-controlled wristwatch, and indicates the positioning information during the positioning information determination operation. In addition, the guideline used for displaying information may be changed between the internal time adjustment operation and the positioning information determination operation.

  In the above description, the satellite radio wave from the GPS satellite is received, but in addition to the satellite radio wave of the GPS satellite, the satellite radio wave of another satellite, for example, the satellite signal of the Gronas may be received. Good. In that case, the positioning operation by the GPS satellite and the positioning operation by the GPS satellite and the Glonus satellite may be distinguished and instructed. For example, the positioning operation by the GPS satellite is instructed by pressing and holding the first push button 60b for a few seconds, and the first push button is pressed again while the receiving circuit 20 is activated and the positioning character 5 is indicated by the second hand 2c. If 60b is pressed, a positioning operation by a GPS satellite or a Glonus satellite may be instructed.

  Here, the time measurement character 6 which is the character of “RX-TME” is arranged in the direction of 2 o'clock, and the positioning character 5 which is the character of “RX-GPS” is 4 o'clock as a character indicating the positioning operation by the GPS satellite. Further, it is possible to arrange characters indicating the positioning operation by the GPS satellite and the Glonus satellite, which are characters of “RX-GPS + GLONASS”, in the direction of 8 o'clock. In this case, when the first push button 60b is pressed again while the positioning character 5 which is the character “RX-GPS” is indicated by the second hand 2c, the GPS satellite which is the character “RX-GPS + GLONASS” by the second hand 2c. In addition, a character indicating the positioning operation by the Glonus satellite is indicated, and it is possible to visually recognize that the positioning operation by the GPS satellite and the Glonus satellite is being performed. In this case, it is intuitively understood that the satellite radio waves are received from about two GPS satellites from the time measurement character 6 arranged in the 2 o'clock direction, and the positioning character 5 arranged in the 4 o'clock direction. Thus, it is intuitively understood that satellite radio waves are received from about four GPS satellites. In addition, it is intuitively understood that satellite radio waves are received from about eight satellites from the characters indicating the positioning operation by the GPS satellite and the Glonus satellite arranged in the 8 o'clock direction.
