[Electric mechanism of electronic watch]
FIG. 4 is an electric control block diagram of the electronic timepiece.
As shown in FIG. 4, the electronic timepiece 10 includes a control device 300 constituted by a CPU (Central Processing Unit), a storage device 150 constituted by a RAM (Random Access Memory) and a ROM (Read Only Memory), and reception. A device (GPS module) 121, an operation unit 157, a drive mechanism 140, and peripheral devices of the time measuring device 155 are provided. Each of these devices transmits and receives data via a data bus. The operation unit 157 includes the crown 50, the A button 61, the B button 62, the C button 63, and the D button 64 shown in FIG. The electronic timepiece 10 includes a rechargeable secondary battery 130 (see FIG. 3) serving as a power source. The secondary battery 130 is charged with electric power supplied from the solar panel 135 via the charging circuit 136.

  The receiving unit 121 is connected to the antenna body 110, processes satellite signals received via the antenna body 110, and acquires GPS time information and position information. The antenna body 110 is transmitted from a plurality of GPS satellites 8 (see FIG. 1) orbiting the earth over a predetermined orbit, and the radio wave of the satellite signal that has passed through the cover glass 33 and the dial ring 40 shown in FIG. Receive.

  Although not shown, the receiving unit 121 receives a satellite signal transmitted from the GPS satellite 8 (see FIG. 1) and converts it into a digital signal, like a normal GPS device, and a radio frequency (RF) unit. The GPS time information and the position information (positioning information) are acquired from the BB unit (baseband unit) that performs correlation determination of the received signal and demodulates the navigation message, and the navigation message (satellite signal) demodulated by the BB unit. And an information acquisition means for outputting. Accordingly, the receiving unit 121 constitutes a receiving unit.

  The RF unit includes a bandpass filter, a PLL circuit, an IF filter, a VCO (Voltage Controlled Oscillator), an ADC (A / D converter), a mixer, an LNA (Low Noise Amplifier), an IF amplifier, and the like. The satellite signal extracted by the bandpass filter is amplified by the LNA, mixed with the VCO signal by the mixer, and down-converted to IF (Intermediate Frequency). The IF mixed by the mixer passes through the IF amplifier and IF filter, and is converted to a digital signal by the ADC.

  The BB unit generates a local code generating unit that generates a local code composed of the same C / A code as that used at the time of transmission by the GPS satellite 8, and a correlation value between the local code and a reception signal output from the RF unit. And a correlation unit to calculate. If the correlation value calculated by the correlation unit is equal to or greater than a predetermined threshold, the C / A code used for the received satellite signal matches the generated local code, and the satellite signal is Can be captured (synchronized). Therefore, the navigation message can be demodulated by correlating the received satellite signal with the local code.

  The information acquisition means acquires GPS time information and position information from the navigation message demodulated by the BB unit. The navigation message includes preamble data, HOW word TOW (also referred to as “Time of Week”, also referred to as “Z count”), and subframe data. There are subframe data from subframe 1 to subframe 5, and each subframe includes, for example, satellite correction data including week number data and satellite health data, and ephemeris (detailed orbit information for each GPS satellite 8). ) And almanac (rough orbit information of all GPS satellites 8). Therefore, the information acquisition means can acquire GPS time information and navigation information by extracting a predetermined data portion from the received navigation message.

  Subframes 4 and 5 include orbit information (almanac) and ionosphere correction information of all satellites, and these are divided into pages and are accommodated in subframes because of the large number of data. That is, the data transmitted in subframes 4 and 5 are each divided into pages 1 to 25, and the contents of different pages are sent in order for each frame. Since it takes 25 frames to transmit the contents of all pages, it takes 12 minutes and 30 seconds to receive all the information of the navigation message. The leap second information (leap second update information) is stored in the page 18 of the subframe 4, and the leap second information can be acquired when the page 18 of the subframe 4 is received.

The time measuring device 155 includes a crystal resonator driven by the power stored in the secondary battery 130 and updates time data using a reference signal based on an oscillation signal of the crystal resonator.

[Storage device]
As described above, the storage device 150 of the electronic timepiece 10 includes a ROM and a RAM. The ROM stores programs executed by the control device 300, time zone information, and the like. The time zone information is data for managing position information (latitude / longitude) of a region (time zone) using a common standard time and a time difference with respect to UTC.
The control device 300 uses the RAM of the storage device 150 as a work area, and performs various calculations, control, and timing by executing a program stored in the ROM. This timing is performed, for example, by counting the number of reference signal pulses from an oscillation circuit (not shown).

  The control device 300 includes time information calculated from GPS time information and time correction parameters, current position information (latitude and longitude) calculated from GPS time information and orbit information, and time zone information stored in the ROM. Correct the internal clock based on The control device 300 controls to drive the drive mechanism 140 so that the internal time is displayed. As a result, the internal time is displayed on the electronic timepiece 10 by the hands 22, 23, 81 (see FIG. 2).

  The storage device 150 does not store orbit information (almanac, ephemeris) of the position information satellite. The electronic timepiece 10 is a wristwatch, and the capacity of the storage device 150 is also limited, and the capacity of the secondary battery 130 is also limited, so that it is difficult to perform long-time reception in order to acquire trajectory information. Because. Therefore, the reception processing of the electronic timepiece 10 is performed in a cold start state that does not have orbit information.

[Control device]
The control device 300 includes a CPU that controls the electronic timepiece 10. The control device 300 includes a first function unit (timer unit) 310, a second function unit (positioning unit) 320, a third function unit (chronograph unit) 330, a time zone setting unit 340, and a time zone correction. Unit 350 and time correction unit 360.

[First function section (time measuring section)]
The first functional unit 310 includes a time measuring unit that operates the receiving unit 121 to perform reception processing in the time measuring mode. In the present embodiment, the first functional unit 310 performs reception processing in the timekeeping mode by automatic reception processing and manual reception processing.
There are two types of automatic reception processing: scheduled automatic reception processing and optical automatic reception processing. That is, the first function unit 310 operates the reception unit 121 when the internal time data being timed reaches the scheduled reception time stored in the storage device 150, and the scheduled automatic reception process in the timing mode. I do.
In addition, the first functional unit 310 operates the receiving unit 121 to measure when the generated voltage or generated current of the solar panel 135 is equal to or higher than the set value and it can be determined that the solar panel 135 is irradiated with sunlight outdoors. Performs automatic optical reception in hour mode. It should be noted that the number of processes for operating the receiving unit 121 in the power generation state of the solar panel 135 may be limited to once a day.
Furthermore, when the user performs the forced reception operation by pressing the B button 62 of the operation unit 157 for the first set time (3 seconds or more and less than 6 seconds), the first function unit 310 operates the reception unit 121 to perform measurement. Perform manual reception processing in hour mode.

  The first function unit 310 acquires at least one GPS satellite 8 by the receiving unit 121, receives a satellite signal transmitted from the GPS satellite 8, and acquires time information. When the time information acquisition is successful, the time correction unit 360 updates the current time display with the acquired time information.

[Second function section (positioning section)]
When the user presses and releases the B button 62 of the operation unit 157 for a second set time (6 seconds or longer), the second function unit 320 operates the reception unit 121 to perform reception processing in the positioning mode. Therefore, the B button 62 is a reception button that instructs execution of reception processing in the time measurement mode and the positioning mode.

When the second function unit 320 starts reception processing in the positioning mode, the reception unit 121 captures at least three, preferably four or more GPS satellites 8 and receives satellite signals transmitted from the respective GPS satellites 8. The time information is acquired, and the position information is calculated and acquired.
When the position information is successfully acquired, the control device 300 acquires and sets time zone data (time difference information) based on the acquired position information (latitude, longitude).
For example, since Japan Standard Time (JST) is a time (UTC + 9) advanced by 9 hours with respect to UTC, when the position information acquired in the positioning mode is Japan, the control device 300 displays time difference information in Japan Standard Time. Set (+9 hours). For this reason, the time displayed by the hands 22, 23, 81 is the time obtained by adding time zone data to UTC.

[Third function section]
The third function unit 330 performs a chronograph function in the present embodiment. When the C button 63 is pressed in the time display mode, the third function unit 330 is executed and the chronograph is started. When the C button 63 is pressed again, the chronograph stops. When the D button 64 is pressed in the stopped state, the chronograph is reset and the time display mode is restored. Accordingly, the C button 63 is a function button that instructs execution of the third function unit 330.

[Time zone setting section]
When the second function unit 320 succeeds in acquiring the position information, the time zone setting unit 340 sets time zone data based on the acquired position information (latitude, longitude). Specifically, time zone data (time zone information, that is, time difference information) corresponding to the position information is selected and acquired from the time zone data storage unit stored in the storage device 150 and set as time zone data.

[Time zone correction section]
When the time zone setting unit 340 sets time zone information, the time zone correction unit 350 corrects the time displayed by the hands 22, 23, 81 using the time zone data.

[Time correction section]
When the time correction unit 360 succeeds in acquiring the time information in the reception process of the first function unit 310 or the second function unit 320, the time correction unit 360 moves the hands 21, 22, and 23 by the driving mechanism 140 based on the acquired time information. Update the time display.

[Control of electronic clock]
Next, control processing of the electronic timepiece 10 will be described with reference to the flowcharts of FIGS.
[Normal time display mode]
FIG. 5 is a flowchart showing the processing of the normal time display mode S1 for displaying the normal time in the electronic timepiece 10. In this normal time display mode, the normal time measured by the time measuring device 155 is displayed by the pointer (hour hand) 23, the pointer (minute hand) 22, and the pointer (small second hand) 81. Further, the date is indicated by a date wheel number displayed in the calendar small window 15.

  In the normal time display mode, the control device 300 determines whether there is a button operation (S2). When it is determined No in S2, the control device 300 determines whether or not the battery voltage detection timing has come (S3). The battery voltage detection timing is set at 1 minute intervals in this embodiment. When it determines with No by S3, the control apparatus 300 returns to S2, and continues a process.

If it determines with Yes by S3, the control apparatus 300 will perform a battery voltage detection process (S4).
Next, the control device 300 determines whether or not the battery voltage (remaining battery level) detected in S4 is equal to or higher than a first threshold value (for example, 4.0 V) (S5).

When the determination is YES in S5, the control device 300 moves the pointer (mode hand) 91 to a position indicating “F” in the scale display portion 93 of the third small window 90, and sets the reception permission mode ( S6).
When determining No in S5, the control device 300 determines whether or not the battery voltage detected in S4 is equal to or higher than a second threshold (eg, 3.6V) (S7).
If the control device 300 determines Yes in S7, that is, if the detected battery voltage is 3.6 V or more and less than 4.0 V, the pointer (mode hand) 91 of the scale display section 93 of the third small window 90 is displayed. It moves to the position where “M” is instructed, and the reception permission mode is set (S8).
When the controller 300 makes a No determination in S7, that is, when the detected battery voltage is less than 3.6 V (including a case where the detected battery voltage cannot be detected), the pointer (mode hand) 91 is displayed on the scale display section 93 of the third small window 90. Is moved to a position instructing “E”, and the reception inhibition mode is set (S9).

Here, the scale “F” is an abbreviation for “Full”, “M” is an abbreviation for “Middle”, and “E” is an abbreviation for “Empty”. Therefore, the user determines whether the secondary battery 130 has a sufficient remaining battery level (in the case of F), whether it is about half (in the case of M), or whether it is in a state in which reception is almost impossible (in the case of E). Easy to judge.
And the control apparatus 300 returns to the start of normal time display mode S1 after the process of S6, S8, and S9.

  When it is determined that there is a button operation in S2 (Yes in S2), the control device 300 executes a function execution process S10 shown in FIG.

[Function execution processing]
When the function execution process S10 is executed, the control device 300 determines how any of the A button 61, the B buttons 62 and 63, and the D button 64 is operated.
Specifically, when the B button 62 that executes a reception-related function is operated, the control device 300 determines whether the B button 62 is pressed for a first set time (for example, 3 seconds or more and less than 6 seconds). (S11) If No in S11, it is determined whether the B button 62 has been pressed for a second set time (for example, 6 seconds or more) (S12). If No in S12, the B button 62 is less than the first set time. It is determined whether it has been pressed (for example, less than 3 seconds) (S13).
In addition, the control device 300 determines whether the A button 61 has been pressed for a predetermined time (for example, 3 seconds or more) when the answer is No in S13 (S14), and whether the C button 63 is pressed if the answer is No in S14. If it is determined that the crown has been pulled from the 0th step to the 1st step (1 step pulling state), whether or not the B button 62 has been pressed for a predetermined time (for example, 3 seconds or more). Determine (S16).

On the other hand, when it is determined Yes in S11, the control device 300 executes the first function unit 310 (S20), and when it is determined Yes in S12, the control device 300 executes the second function unit 320 (S30), S13. If it is determined as Yes, the reception result display process is executed (S17). However, if reception is prohibited in S9, the processing in S20 and S30 is prohibited.
The control device 300 executes a reception permission (ON) / prohibition (OFF) switching process when it is determined to be Yes in S14 (S18), and when it is determined Yes in S15, the third functional unit. 330 is executed (S40), and if YES is determined in S16, a DST (Daylight Saving Time) ON / OFF switching process is executed (S19).
And the control apparatus 300 returns to normal time display mode S1 of FIG. 5, when each process S20, S30, S17, S18, S40, S19 is performed and when it determines with No in S16.
Hereinafter, the processes S20, S30, S17, S18, S40, and S19 will be described.

[First function section execution processing]
FIG. 7 is a flowchart showing the first function section execution process (time measurement reception process) S20.
When the execution process S20 of the first function unit 310 is started by pressing the B button 62 for the first set time, as shown in FIG. 7, the first function unit 310 starts reception in the timekeeping mode. (S21). Further, the first function unit 310 moves the pointer (mode hand) 91 to a position for instructing the time measurement mode, that is, a position for instructing “TIME” on the scale display unit 93 (S22).

The first function unit 310 determines whether the C button 63 has been pressed (S23). If the first function unit 310 determines Yes in S23, the first function unit 310 stops the reception (S24), and starts the execution process S40 of the third function unit 330.
That is, in this embodiment, if the start button (C button 63) of the chronograph function is pressed during reception, reception is stopped and the chronograph is started. Details of the execution process S40 of the third functional unit 330 will be described later.

If the first function unit 310 determines No in S23, the first function unit 310 determines whether the A button 61 has been pressed (S25). If the first function unit 310 determines Yes in S25, the first function unit 310 stops receiving (S24), and ends the first function unit execution process S20. That is, in the present embodiment, when the A button 61 is pressed during reception in the timekeeping mode, the first function unit 310 cancels and stops the reception process. Therefore, the A button 61 is a button for instructing to interrupt the execution of the first function unit 310.
If the first functional unit 310 determines No in S25, it determines whether the reception in the timekeeping mode has been successful (S26). If it is determined No in S26, the first functional unit 310 determines whether a preset reception time (for example, 30 seconds) has elapsed (S27). If it is determined No in S27, the first function unit 310 returns to S23 for processing. Continue.
On the other hand, if the first function unit 310 determines Yes in S27, that is, if the satellite signal is not successfully received even after 30 seconds have elapsed, the electronic timepiece 10 is disposed in an environment in which the satellite signal cannot be received. The first function unit execution process S20 is terminated.

  If the first function unit 310 succeeds in receiving and determines Yes in S26, the first function unit 310 performs time correction processing using the acquired time information (S28), and the display time (current time) displayed by the hands 22, 23, 81 ) Is updated (S29). The current time is the time at a location corresponding to the time zone set by the previous positioning reception or the user operating the crown 50. Normally, the user wearing the electronic timepiece 10 stays there. It is the local local time.

  The first function unit 310 determines the first function when the determination in S27 is Yes, that is, when reception is failed, when the display time update is completed in S29, and when the determination is Yes in S25, that is, when reception is instructed. The section execution process S20 is terminated, and the process returns to the normal time display mode S1, as shown in FIGS.

[Second function section execution processing]
FIG. 8 is a flowchart showing the second function section execution processing (positioning reception processing) S30.
When the execution process S30 of the second function unit 320 is started by pressing the B button 62 for the second set time, as shown in FIG. 8, the second function unit 320 starts reception in the positioning mode ( S31). Further, the second function unit 320 moves the pointer (mode hand) 91 to a position for instructing the positioning mode, that is, a position for instructing “FIX” on the scale display unit 93 (S32).

  The second function unit 320 determines whether the C button 63 has been pressed (S33). If the second function unit 320 determines Yes in S33, the second function unit 320 stops the reception (S34) and starts the execution process S40 of the third function unit 330, as in the first function unit 310.

If the second function unit 320 determines No in S33, it determines whether the A button 61 has been pressed (S35). If the second function unit 320 determines Yes in S35, the second function unit 320 stops receiving (S34), and ends the second function unit execution process S30. That is, even when the A button 61 is pressed during reception in the positioning mode, the second function unit 320 cancels the reception process and stops, as in reception during the timekeeping mode. Therefore, the A button 61 is also used as a button for instructing to interrupt the execution of the first function unit 310 and the second function unit 320.
When the second function unit 320 determines No in S35, the second function unit 320 determines whether the reception in the positioning mode is successful (S36). If it is determined No in S36, the second function unit 320 determines whether a preset reception time (for example, 2 minutes) has elapsed (S37). If it is determined No in S37, the second function unit 320 returns to S33 for processing. Continue.
On the other hand, if the second function unit 320 determines Yes in S37, that is, if the satellite signal is not successfully received after two minutes, the electronic timepiece 10 captures at least three GPS satellites 8 and receives the satellite signal. And the second function unit execution process S30 is terminated.

  If the second function unit 320 succeeds in reception and determines Yes in S36, the second function unit 320 performs time correction processing using the acquired time information (S38), and corrects the time zone based on the calculated position information (S39). Then, the hands 22, 23, 81 are moved to update the current time (local time) of the corrected time zone (S 50).

  If the second function unit 320 determines Yes in S37, that is, if reception has failed, if the display time update ends in S50, or if it is determined Yes in S35, that is, if reception is instructed, the second function unit 320 The function unit execution process S30 is terminated, and the process returns to the normal time display mode S1, as shown in FIGS.

[Reception result display]
When the reception result display process S17 is executed by pressing the B button 62 for less than a first set time (for example, 3 seconds), the control device 300 displays the previous reception result. Specifically, the control device 300 moves the pointer (mode hand) 91 to a position for instructing TIME if the previous reception mode is the timekeeping mode, and to a position for instructing FIX if it is the positioning mode. To do. Further, the control device 300 moves the pointer (small second hand) 81 to a position indicating “Y” of the second small window 80 if the previous reception result is successful, and if the previous reception result is unsuccessful. The second small window 80 is moved to a position indicating “N”. This reception result display ends when a predetermined time (for example, 5 seconds) elapses and returns to the normal time display mode S1. The reception result display may be terminated by pressing the B button 62 again or pressing a button set for display cancellation (for example, the D button 64).

[Reception ON / OFF setting]
When the reception ON / OFF switching process S18 is executed by pressing the A button 61 for a set time (for example, 3 seconds or more), the control device 300 switches each reception permission (ON) and prohibition (OFF) mode. Switch alternately. Specifically, the control device 300 moves the pointer (mode hand) 91 to a position indicating “OFF” in the 10 o'clock direction of the scale display unit 93 in the reception inhibition mode (OFF mode, in-flight mode). . That is, the pointer 91 is moved to a position indicating “OFF” between “F” and “TIME” on the scale display unit 93.
On the other hand, in the reception permission mode (ON), control device 300 moves pointer 91 to a position (any one of F, M, and E) that indicates the battery voltage level as in the normal time display mode.
Then, when the reception prohibit mode (OFF mode) is set, the control device 300 prohibits the reception processing (both automatic reception and manual reception) of the first function unit 310 and the second function unit 320. That is, even if the B button 62 is pressed for the first set time or the second set time, the first function unit 310 or the second function unit 320 does not start the process and moves the pointer 91 to the “OFF” position. For this reason, it is possible to prohibit the start of a satellite signal reception operation when boarding an airplane, and even if a reception operation is performed, the pointer 91 indicates the position of “OFF”. You can easily grasp that it is set to.
The display of the reception inhibition mode (OFF) is terminated when a predetermined time (for example, 5 seconds) has elapsed, and the normal time display mode S1 is resumed. The display of the reception prohibition mode (OFF) may be ended by pressing the A button 61 again or pressing a button set for display cancellation (for example, the D button 64).

[Third function unit execution process]
FIG. 9 is a flowchart showing the third functional unit execution process (chronograph process) S40.
When the execution process S40 of the third function unit 330 is started by pressing the C button 63, the third function unit 330 starts the chronograph function as shown in FIG. 9 (S41).
Then, the third function unit 330 starts to move the pointer (1/5 second chronograph hand) 21, the pointer (minute chronograph hand) 71, and the pointer (hour chronograph hand) 91 (S42). Specifically, the pointer 21 starts to move clockwise from the 12 o'clock position (0 second position). In addition, the pointer 91 moves to the initial position of the 12 o'clock position that is 0 hour. In addition, since the pointer 71 is located at the 60 minute position which is 0 minute in the normal time display mode, the state 71 starts in that state.

The pointer 21 moves once every 60 seconds, and the pointer 71 moves one scale (one minute) every time the pointer 21 makes one round, that is, every minute. Further, the pointer 71 moves one turn every 60 minutes, and the pointer 91 moves one scale (one hour) every time the pointer 71 makes one turn, that is, every hour.
The pointer 91 moves to a position of 6 hours at the maximum. Therefore, the third function unit execution process (chronograph process) S40 can measure up to 6 hours.

The third function unit 330 determines whether the C button 63 is pressed during the operation of the chronograph (S43), and stops the chronograph operation when it is pressed (S44). Then, the hands 21, 71, 91 are also stopped (S45).
The third function unit 330 determines whether or not the D button 64 is pressed while the chronograph operation is stopped (S46). If No in S46, the third function unit 330 determines whether or not the C button 63 is pressed (S47).
If No in S47, the third function unit 330 returns to S46 and continues the process.
In the case of Yes in S47, that is, when the C button 63 is pressed again, the third function unit 330 returns to S41 and restarts the chronograph operation.

In addition, when the D button 64 is pressed and it is determined Yes in S46 while the chronograph operation is stopped, the third function unit 330 resets (suspends) the chronograph operation (S48). Therefore, the D button 64 is a button for instructing to interrupt the execution of the third function unit 330. Then, the third function unit 330 returns the hands 21 and 71 to the initial 12 o'clock position, and the hands 91 return to the battery remaining amount display as in the normal time display mode (S49).
And the 3rd function part 330 complete | finishes 3rd function part execution process S40, and returns to normal time display mode S1, as shown in FIG.

[Check and change time zone]
When the crown 50 is pulled down by one step, the time zone being set can be confirmed. The control device 300 moves the pointer 21 to a position instructing display of the city name and time difference of the currently set time zone.
In this state, when the crown 50 is rotated forward (clockwise), the control device 300 increments the time zone time difference by “+1” and the pointer 21 also moves clockwise. When the crown 50 is rotated in the reverse direction (counterclockwise), the control device 300 decrements the time zone time difference by “−1” and the pointer 21 also moves counterclockwise.
With the change of the time zone, the control device 300 changes the indicated positions of the hands 22 and 23 to the time of the time zone indicated by the hands 21.

[DST ON / OFF setting]
When the crown 50 is pulled down by one step, the pointer 91 displays DST ON / OFF. When the B button 62 is pressed for 3 seconds or longer in this state, the control device 300 executes the DST ON / OFF switching process S19. The control device 300 alternately switches between ON and OFF modes of DST.
When the crown 50 is pushed down to the 0th position, the DST ON / OFF switching process S19 ends, and the process returns to the normal time display mode S1.

[Effects of First Embodiment]
The electronic timepiece 10 according to the first embodiment of the present invention described above has the following effects.
That is, by changing the pressing time of the B button 62, the first function unit execution process (time measurement reception process) S20 by the first function unit 310 and the second function unit execution process (positioning reception by the second function unit 320) are performed. Process) S30 can be executed. Further, by pressing the C button 63, the third function unit execution process (chronograph process) S40 by the third function unit 330 can be executed. As described above, the execution of the function units 310, 320, and 330 can be started by one operation of each of the buttons 62 and 63. Therefore, after executing the mode selection operation, the execution start operation is performed twice. The operability can be improved as compared with the case where the operation is executed. Therefore, the user can handle the multifunctional electronic timepiece 10 with good operability, and the usability can be improved.

In addition, a pointer 91 serving as a mode hand is provided, and when the function units 310, 320, and 330 are executed, the user can easily check the indicated position of the pointer 91 to easily perform the currently executed function. I can grasp. Therefore, the user can easily confirm whether the intended function is being executed, and usability can be improved in this respect as well.
Further, the pointer 91 as a mode hand functions as an hour chronograph hand when the chronograph function by the third function unit 330 is executed, and is used as an indicator hand for indicating the time of the chronograph. The user can simultaneously confirm that the third function is being executed and the measurement value obtained by the chronograph function.

  Further, even when the first function unit 310 or the second function unit 320 is being executed, the third function unit 330 can be executed by pressing the C button 63 to start the chronograph. For this reason, since the time measurement operation can be prioritized over other operations, it is possible to meet the desire of the user who wants to start the time measurement, and usability can be improved in this respect as well.

The time measurement reception by the first function unit 310 and the positioning reception by the second function unit 320 are selected by changing the pressing time of the same B button 62, and the third function unit 330 selects another C button 63. Since it is executed by pressing, the operability can be improved while suppressing the number of buttons. Therefore, both the number of buttons and the operability can be achieved in a wristwatch.
Further, since the A button 61 for instructing the interruption of the execution of the first function unit 310 and the second function unit 320 and the D button 64 for instructing the interruption of the execution of the third function unit 330 are provided, The A button 61 can also be used as a button for instructing interruption of reception processing in positioning mode. Therefore, there is no need to separately provide buttons for interrupting execution of the first function unit 310 and the second function unit 320, and the number of buttons can be reduced.
Also, in both the timekeeping mode and the positioning mode, the execution can be interrupted with the A button 61, the execution of the chronograph function can be interrupted with the D button 64, and the interrupt button is set for each function. It is easy to grasp the buttons and the operability can be improved.

[Second Embodiment]
Next, 2nd Embodiment of this invention is described based on drawing.
FIG. 10 is a front view showing an electronic timepiece 10A according to the second embodiment of the present invention.
The electronic timepiece 10A is different from the first embodiment in that the pointer 21 displays the mode of the reception result or the reception result. Therefore, the pointer 91 functions in the same manner as the hour chronograph hand, but only the remaining battery level is displayed as the mode hand.
Therefore, only differences from the first embodiment will be described in detail.

[Normal time display mode]
Also in the electronic timepiece 10A of the second embodiment, the control device 300 controls the same normal time display mode as that in FIG. 5 of the first embodiment. Therefore, the battery voltage detection process (S4 in FIG. 5) is performed at regular time intervals, and the detection result is displayed with the pointer 91. That is, if the detected battery voltage is equal to or higher than the first threshold value (4.0 V), “F” is indicated by the pointer 91, and if the detected battery voltage is equal to or higher than the second threshold value (3.6 V) and lower than the first threshold value, “F” is indicated. “M” is instructed, and if it is less than the second threshold value, “E” is instructed by the pointer 91.
When a button operation is performed, the same function execution processing as that shown in FIGS.

[Receive operation]
That is, when the B button 62 is pressed for the first set time, the electronic timepiece 10A executes the first function unit execution process S20 by the first function unit 310. In addition, when the B button 62 is pressed for the second set time, the electronic timepiece 10A executes the second function unit execution process S30 by the second function unit 320. Since each process S20 and S30 is the same as 1st Embodiment, description is abbreviate | omitted.
In the electronic timepiece 10A, the mode hand indicating the reception mode is the pointer 21. For this reason, when the time measurement mode reception processing is being performed by the first function unit 310, the pointer 21 indicates the position of “TIME” displayed on the dial 11, and the second function unit 320 performs the positioning mode. When the reception process is performed, the position of “FIX” is indicated.

The electronic timepiece 10A performs a reception ON / OFF switching process when the A button 61 is pressed for 3 seconds or more. When the reception prohibit mode (OFF mode, in-flight mode) is set, the control device 300 moves the pointer (mode hand) 21 to a position where the dial 11 is instructed to be “OFF”.
Further, when the reception prohibit mode (OFF mode) is set, even if the B button 62 is pressed for the first set time or the second set time, the first function unit 310 and the second function unit 320 start processing. Without moving, the pointer 21 is moved to the “OFF” position.

[Chronograph]
