JP 2010-78546 A

  By the way, when one function is assigned to one operation unit (button or the like) in the electronic timepiece, it is necessary to provide operation units as many as the functions of the electronic timepiece. For example, Patent Document 1 can be configured to switch to the time measurement mode by pressing one button and to switch to the positioning mode by pressing the other button. However, when the electronic timepiece is provided with other functions such as a time correction function by a button operation and a calendar display, for example, it is necessary to add an operation unit such as a button, and there is a problem that the configuration becomes complicated.

  An object of the present invention is to provide an electronic timepiece and an electronic device that can be simplified in configuration.

  The electronic timepiece of the present invention is an electronic timepiece that corrects internal time information based on a satellite signal transmitted from a position information satellite, and is based on an external operation member and an input operation of the external operation member. A mode setting unit for setting the operation mode of the receiver, a receiving unit for receiving the satellite signal transmitted from the position information satellite, and controlling the operation of the receiving unit based on the operation mode to receive the satellite signal. A reception control unit; and a time correction unit that corrects the internal time information based on a satellite signal received by the reception unit. The mode setting unit is an input in which the external operation member is continuously operated. A first mode for receiving satellite signals from one or more of the position information satellites based on a duration and correcting the internal time information based on time information included in the received satellite signals; A satellite signal is received from the position information satellite above, and the operation mode is switched to a second mode in which the internal time information is corrected based on time information and position information included in the received satellite signal. It is characterized by that.

  The input duration is the time from when an input operation to the external operation member is started until the input operation is stopped. For example, a button that is in an input state when the external operation member is pressed Then, it indicates the time during which the button is continuously pressed (the time from when the button is pressed to when the pressed state is released).

According to the present invention, the mode setting unit switches the operation mode between the first mode and the second mode according to the input duration when the external operation member is operated.
Here, the first mode is a mode in which time is corrected based on time information included in satellite signals from at least one position information satellite. In the first mode, the received satellite signal may be only a satellite signal from one position information satellite, for example. In such a first mode, the internal time information can be corrected even in an environment where the reception sensitivity is low. On the other hand, in the second mode, satellite signals from at least three or more position information satellites are required. However, highly accurate time correction using time information and position information included in these satellite signals is possible.
And in this invention, since such 1st mode and 2nd mode are switched by the input continuation time of one external operation member, in order to implement the process of each operation mode, it corresponded to each operation mode. There is no need to provide a plurality of external operation members, and the two modes can be switched and set by using only one external operation member. Thereby, in this invention, the structure of an electronic timepiece can be simplified and it can contribute also to size reduction of an electronic timepiece.

In the electronic timepiece of the invention, the input duration when the mode setting unit sets the first mode as the operation mode is the input duration time when the mode setting unit sets the second mode as the operation mode. It is preferably shorter than the input duration time.
According to the present invention, the input duration when the mode setting unit sets the first mode is set to be shorter than the input duration when the second mode is set.
In general, the time correction in the first mode can be performed in a shorter time than the time correction in the second mode, and therefore the frequency of use is increased. In the present invention, the input continuation time corresponding to the first mode is set shorter than the input continuation time corresponding to the second mode. The convenience of time correction by the person can be improved.

In the electronic timepiece of the invention, when the operation mode set by the mode setting unit is the second mode, the time correction unit is based on the time information and the position information included in the satellite signal, It is preferable to correct the internal time information by calculating the standard time at the current position of the electronic timepiece.
According to the present invention, in the second mode, the time correction unit calculates the current position of the electronic timepiece based on the time information and the position information included in the received satellite signal, and the standard time (local time) at the current position. ) To correct the internal time information. As a result, the internal time information can be accurately adjusted to the local time at the current position, and the convenience of the electronic timepiece can be enhanced particularly when moving across regions with different time differences.

  In the electronic timepiece of the invention, a reception result storage unit that stores a reception result indicating whether or not the satellite signal has been successfully received by the reception unit, a reception result display unit that displays the reception result, and the reception result A third mode for displaying the reception result stored in the reception result storage unit on the basis of the input duration time. Is set as the operation mode, and the result display control unit preferably causes the reception result display unit to display the reception result when the third mode is set as the operation mode.

According to the present invention, when a reception process is performed by the reception control unit, a reception result indicating whether or not the reception process is successful is stored in the reception result storage unit. Then, based on the input continuation time when the external operation member is operated, the mode setting unit receives the reception result stored in the reception result storage unit by the result display control unit when the operation mode is set to the third mode. The result is displayed on the reception result display section.
In such a configuration, the user can easily confirm whether or not the result of the previous reception process was successful. Further, by displaying such a reception result, the user can easily determine the timing of time adjustment, so that the convenience of the electronic timepiece can be improved.
In addition, since it is not necessary to provide a separate external operation member for displaying the reception result, the configuration of the electronic timepiece can be simplified and the size can be reduced as in the case of the above invention.

In the electronic timepiece according to the aspect of the invention, the input duration time when the mode setting unit sets the third mode as the operation mode, the mode setting unit sets the first mode and the second mode as the operation mode. It is preferable that the input duration is shorter than that in the case of setting.
Here, when the reception result in the previous reception process can be referred to, the user generally determines whether or not to perform time correction after confirming the reception result. For this reason, the third mode for confirming the reception result is used more frequently than the first mode and the second mode for performing time correction.
On the other hand, in this invention, the input continuation time for setting to 3rd mode is set shorter than the input continuation time when the 1st mode and 2nd mode which implement time correction are set. For this reason, the reception result display of the 3rd mode with high use frequency can be implemented quickly, and the convenience of an electronic timepiece can be improved.

In the electronic timepiece according to the aspect of the invention, it is preferable that the electronic timepiece includes an operation time display unit that displays an operation time during which the external operation member is continuously operated.
The “operation time” refers to the time that the input operation has not been released and has been continued since the input operation of the external operation member started.
According to the present invention, the operation time of the external operation member is displayed on the operation time display unit. That is, while the external operation member is continuously operated, the operation time is displayed on the operation time display unit. For this reason, the user can easily grasp the operation time. Therefore, for example, it can be easily confirmed how much the external operation member should be continuously operated with respect to the input duration time of the target operation mode.

In the electronic timepiece of the invention, it is preferable that the electronic timepiece has a setting mode display unit that displays the operation mode corresponding to an operation time during which the external operation member is continuously operated.
Note that, in the “operation time” of the present invention, as in the case of the above-described invention, it refers to the time that the input operation is not released from the time when the input operation of the external operation member is started.
According to the present invention, the operation mode corresponding to the current operation time is displayed on the display unit corresponding to the operation time from the operation start time point of the external operation member.
For example, when the input continuation time for setting to the first mode is from 0 seconds to t1 seconds and the input continuation time for setting to the second mode is t1 seconds or more, the time from the operation start time of the external operation member is During the operation time of 0 to t1 seconds, the setting mode display section displays that the first mode can be set. Further, when the operation time from the operation start time of the external operation member becomes t1 seconds or more, the setting mode display unit displays that the second mode can be set.
In such a configuration, the user can easily set the target operation mode by continuously operating the external operation member while confirming the operation mode displayed on the setting mode display unit.

The electronic timepiece of the invention preferably has an execution mode display unit that displays the operation mode being executed.
According to the present invention, while the process corresponding to the operation mode set by the mode setting unit is being performed, the operation mode is displayed on the execution mode display unit. It is possible to easily check whether the operation is being performed.

An electronic apparatus according to the present invention includes the electronic timepiece as described above.
According to the present invention, the operation mode of the electronic timepiece can be easily switched by one external operation member, and the configuration can be simplified. Therefore, it is possible to simplify the configuration of an electronic device including such an electronic timepiece.

Count time (operation time). Further, the operation time display control unit 354 of the display control unit 35 moves the second hand 133 to the “0” position at the timing when the A button 6 is pressed, and drives the second hand 133 for a second according to the operation time.
The mode display control unit 353 moves the first pointer 141 to the “I” scale position.

  Next, the wristwatch 1 determines whether or not the pressed state of the A button 6 is released (S2). That is, when the pressed state determination unit 31 determines that the pressed state of the A button 6 is released, the mode setting unit 32 acquires the operation time at the time when the pressed state is released as the input duration time T. Then, the mode setting unit 32 determines whether or not the input duration time T is a value within the first input period (between 0 seconds and T1 seconds).

If “Yes” is determined in S2, that is, if the mode setting unit 32 determines that the input duration T is a value within the first input period, the mode setting unit 32 receives the operation mode. Set to result display mode. Thereby, the wristwatch 1 executes processing according to the reception result display mode (S3).
In S3, the result display control unit 355 of the display control unit 35 refers to the reception result stored in the reception result storage unit 264, and when the reception result at the previous reception process is successful, the second hand 133 is moved. The dial 2 is moved to the “Y” scale position. On the other hand, if the result of the reception process is unsuccessful, the result display control unit 355 moves the second hand 133 to the “N” scale position of the dial 2.
The result display time for displaying the reception result in this reception result display mode may be, for example, a time set by the user or a predetermined time set in advance. At this time, while the reception result is displayed by the result display control unit 355, the mode display control unit 353 holds the first pointer 141 at the scale position “I”. Then, after the result display time has elapsed, the time display control unit 351 drives the display drive unit 221 to return to the normal time display mode.

On the other hand, when it is determined “No” in S2, that is, when the pressed state determination unit 31 determines that the pressed state is not released, the mode setting unit 32 determines that the operation time is the maximum of the first input period. It is determined whether or not a time T1 that is a value has been exceeded (S4).
If the mode setting unit 32 determines “No” in S4, the process returns to S2.
In S4, when the mode setting unit 32 determines “Yes”, the mode display control unit 353 moves the first pointer 141 to the scale position “II”.

  Thereafter, the mode setting unit 32 determines whether or not the pressed state of the A button 6 is released (S5). That is, similarly to S2, the mode setting unit 32 acquires the input duration T, and is this input duration T a value within the second input period (between time T1 seconds and time T2 seconds)? Judge whether or not.

If the mode setting unit 32 determines “Yes” in S5, the operation mode is set to the timekeeping mode, and the wristwatch 1 executes processing according to the timekeeping mode (S6).
In S6, the reception control unit 33 starts the satellite signal reception process by controlling the GPS device 25 in the time measurement mode. Then, the reception control unit 33 determines whether the time information has been received within the set time. Here, the set time may be set to a time sufficient for receiving time information, such as 30 seconds to 1 minute. During the reception process, the mode display control unit 353 maintains the position of the first pointer 141. That is, the first pointer 141 is in a state in which the operation mode indicates the scale position of “II”, which is the time measurement mode, during the reception process in the time measurement mode.
When the GPS device 25 successfully receives the time information, the timekeeping mode correction unit 341 corrects the internal time information based on the time information included in the received satellite signal. After the time adjustment processing is completed, the time display control unit 351 drives the hands 3, the first hands 141, and the second hands 151 based on the corrected internal time information, and returns to the normal time display mode.

On the other hand, when the mode setting unit 32 determines “No” in S5, that is, when it is determined that the pressed state is not released, the mode setting unit 32 determines that the operation time is the maximum value of the second input period. It is determined whether or not the time T2 is exceeded (S7).
If the mode setting unit 32 determines “No” in S7, the process returns to S5.

In S7, when the mode setting unit 32 determines “Yes”, the mode display control unit 353 moves the first pointer 141 to the scale position “III”.
Further, when the operation time exceeds the time T2, the mode setting unit 32 determines that the input duration T is a value within the third input period, sets the operation mode to the positioning mode, and the wristwatch 1 enters the positioning mode. A corresponding process is executed (S8).
In S8, the reception control unit 33 starts the satellite signal reception process by controlling the GPS device 25 in the positioning mode.
And the reception control part 33 determines whether position information and time information were able to be received within setting time. The set time may be set to a time sufficient for receiving position information, for example, 30 seconds to 1 minute from a wristwatch. During the reception process, the mode display control unit 353 maintains the position of the first pointer 141. That is, the first pointer 141 is in a state of pointing to the scale position of “III” whose operation mode is the positioning mode during the reception process in the positioning mode.

If the GPS device 25 has successfully received the position information and time information, the positioning mode correction unit 342 acquires the position information and time information included in the received satellite signal and calculates the current position. . In addition, the positioning mode correction unit 342 refers to the time difference information stored in the ROM 261 and acquires the time difference information at the current position. Then, the positioning mode correcting unit 342 calculates the standard time (local time) of the current position from the acquired time information and the time difference information, and corrects the internal time information. After the time adjustment processing is completed, the time display control unit 351 drives the hands 3, the first hands 141, and the second hands 151 based on the corrected internal time information, and returns to the normal time display mode.
When the reception process and the time correction process are performed in the positioning mode, the position display control unit 352 drives the first hand 141 and the second hand 151 based on the calculated latitude / longitude of the current position, A process of displaying the current position by the first small clock 4 and the second small clock 5 may be performed.

[Effects of Embodiment]
As described above, in the wristwatch 1 of the present embodiment, the mode setting unit 32 switches between the time measurement mode and the positioning mode according to the input duration time during which the A button 6 is continuously pressed. . When the time measurement mode is set, the reception control unit 33 acquires time information from the satellite signals of one or more GPS satellites 10, and the time measurement mode correction unit 341 of the time correction unit 34 The internal time information is corrected based on the information. Further, when the positioning mode is set, the reception control unit 33 acquires time information and position information from satellite signals of three or more GPS satellites 10, and the positioning mode correction unit 342 of the time correction unit 34 acquires The internal time information is corrected from the obtained time information.
In such a configuration, it is not necessary to provide a plurality of external operation members in order to switch between the time measurement mode and the positioning mode, and the configuration can be simplified. In particular, in the wristwatch 1 having a plurality of functions such as displaying position information as in the present embodiment, if a plurality of external operation members are provided corresponding to the plurality of functions, the configuration becomes complicated. There arises a problem that the wristwatch 1 is increased in size and the operation method is complicated. In contrast, in the present embodiment, the two operation modes of the time measurement mode and the positioning mode can be switched and executed by only one external operation member, that is, the A button 6, so that the configuration can be simplified. The wristwatch 1 can be downsized.

  In the wristwatch 1 of the present embodiment, when the positioning mode is set by the mode setting unit 32, the positioning mode correction unit 342 of the time correction unit 34 calculates the current position based on the acquired position information, and at the current position. Time difference information is acquired, and based on the time difference information and the acquired time information, the local time at the current position is calculated to correct the internal time information. For this reason, for example, when a user travels across regions with different time differences due to travel or the like, the time can be corrected to the local time at the destination, and the convenience of the wristwatch 1 can be improved.

Furthermore, the mode setting unit 32 of the present embodiment can set the reception result display mode when the input duration is a value within the first input period. In this reception result display mode, the result display control unit 355 of the display control unit 35 refers to the reception result at the time of the previous reception process stored in the reception result storage unit 264, and when the reception result is successful, The pointer 3 (second hand 133) is moved to the “Y” scale position of the dial plate 2. If reception fails, the pointer 3 (second hand 133) is moved to the “N” scale position of the dial plate 2.
Thereby, in the present embodiment, the previous reception result can be displayed. For example, the user can easily determine whether or not to correct the time in the timekeeping mode or the positioning mode by checking the reception result. can do.
Further, since the reception result display mode, the time measurement mode, and the positioning mode are set by the input duration time that is the time when the A button 6 is continuously pressed, each operation mode is set in the same manner as in the above invention. Therefore, there is no need to provide corresponding external operation members, and the configuration can be simplified.

In this embodiment, the input continuation time for setting the reception result display mode is set shorter than the input continuation time for setting the time measurement mode or the positioning mode.
In other words, the time adjustment by the time measurement mode or the positioning mode is generally performed after determining whether or not the previous reception process and time correction process were successful. Use frequency is higher than time correction. Therefore, by setting the input duration corresponding to the reception result display mode having a high usage frequency shorter than the input duration corresponding to the time measurement mode or the positioning mode, the convenience of the user can be further improved. it can.

In the present embodiment, the operation time display control unit 354 moves the second hand 133 of the pointer 3 to the “0” second position of the dial 2 when the A button 6 is pressed, and corresponds to the operation time of the A button 6. The second hand 133 is moved so as to That is, the dial 2 and the pointer 3 also function as an operation time display unit of the present invention.
For this reason, for example, the operation time when the A button 6 is operated, the operation state of the A button 6 (pressed, etc.) Whether or not the operation of the A button 6 has been confirmed by the state determination unit 31 can be easily confirmed.

In the present embodiment, the mode display control unit 353 moves the first pointer 141 to the “I” scale position in the second region 144 when the A button 6 is pressed. Further, the mode display control unit 353 moves the first pointer 141 to the “II” scale position of the second region 144 after the maximum time “T1” of the first input period has elapsed. Furthermore, after the maximum time “T2” of the second input period has elapsed, the mode display control unit 353 moves the first pointer 141 to the “III” scale position of the second region 144. That is, the mode display control unit 353 causes the display unit 222 to display which operation mode can be selected according to the operation time of the A button 6.
For this reason, the user can confirm the operation modes that can be selected by the first pointer 141. In the present embodiment, in addition to the display of the operation time by the mode display control unit 353, the operation mode for the operation time of the A button 6 is displayed by displaying the selectable operation mode by the operation time display control unit 354. Each can be confirmed while comparing.

  In the present embodiment, the mode display control unit 353 displays the first pointer 141 while reception processing is being performed by the reception control unit 33 and while reception result display is being performed by the result display control unit 355. Maintain position. For this reason, the user can easily confirm which operation mode the process currently being executed corresponds to.
