JP 2000-98064 A

  By the way, in an electronic timepiece equipped with a chronograph function, measurements such as split time (intermediate elapsed time) and total time (total elapsed time from measurement start to measurement stop, last split time) measured by the chronograph function, etc. For example, the data is sequentially added and stored in a predetermined memory area in the order measured. Thereby, the user can read and confirm measurement data later.

  However, in the electronic timepiece described above, the capacity of the memory that can be mounted is limited, and measurement data is stored in all predetermined memory areas (memory areas prepared in advance for storing measurement data). It becomes impossible to save the subsequent measurement data when the free space of the memory runs out. Therefore, conventionally, in an electronic timepiece, for example, after starting measurement by the chronograph function, if the free space of the memory is exhausted when the intermediate split time is saved, the total time of the measurement cannot be saved. There was a problem that convenience was bad.

  The present invention has been made in view of the above points, and an object thereof is to provide an electronic timepiece that can improve convenience in an electronic timepiece having a chronograph function.

And an electronic timepiece.

  Another aspect of the present invention is the above-described electronic timepiece, wherein the control unit sets the intermediate elapsed time measured by the measurement unit in response to an instruction to measure the intermediate elapsed time. When the free space that can be stored in the storage unit is smaller than the combined capacity of the capacity for storing the intermediate elapsed time and the capacity for storing the total elapsed time, the intermediate elapsed time is stored in the storage unit. The total elapsed time is stored in the storage unit after the measurement stop is instructed without being stored in the storage unit.

  According to another aspect of the present invention, there is provided an electronic timepiece as described above, wherein a free space that can be stored in the storage unit is greater than a combined capacity of a capacity for storing the halfway elapsed time and a capacity for storing the total elapsed time. A determination unit that determines whether or not there is a small amount, and the control unit uses the determination unit to determine the storage unit based on a combined capacity of a capacity for storing the intermediate elapsed time and a capacity for storing the total elapsed time. When it is determined that the available free space is small, the elapsed time is not stored in the storage unit.

  Another aspect of the present invention is the above-described electronic timepiece, in which the control unit stores the total elapsed time in the storage unit, and the storage unit has a capacity for storing the total elapsed time. When the storable free space is small, the total elapsed time is overwritten and stored in the intermediate elapsed time stored immediately before.

  Another aspect of the present invention is the above-described electronic timepiece, wherein the control unit stores the intermediate elapsed time measured by the measurement unit in response to an instruction to measure the intermediate elapsed time. And when the free space that can be stored in the storage unit is smaller than the capacity for storing the intermediate elapsed time, the intermediate elapsed time is overwritten on the intermediate elapsed time stored immediately before and stored.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[First Embodiment]
FIG. 1 is a front view showing an external configuration of an electronic timepiece 10 according to one embodiment (first embodiment) of the present invention. The electronic timepiece 10 shown in FIG. 1 includes a plurality of (four in this embodiment) buttons A to D and a display unit 105. The buttons A to D are the operation input unit 102 that receives operation inputs. The function of each button A to D will be described later. The display unit 105 displays, for example, current time and measurement time.

  The electronic timepiece 10 has a chronograph (stopwatch) function, and measures the measured time by measuring the elapsed time from the time point when the operation input related to the measurement start is received (when the measurement start is instructed). The time is displayed on the display unit 105.

  FIG. 2 is a schematic block diagram showing an example of the internal configuration of the electronic timepiece 10 in the present embodiment. The electronic timepiece 10 includes a processing unit 101, an operation input unit 102, a storage unit 103, an oscillation unit 104, a display unit 105, a light emitting unit 106, and a power supply unit 107.

  The processing unit 101 is, for example, a CPU (Central Processing Unit), and performs processing for realizing the functions of the electronic timepiece 10. For example, the processing unit 101 realizes a function corresponding to each button A to D based on an instruction according to an operation input received by the buttons A to D (operation input unit 102). In addition, the processing unit 101 measures the current time or measures the time using the chronograph function based on the time signal input from the oscillation unit 104. For example, the processing unit 101 includes a measurement unit 111, a control unit 112, and a determination unit 113.

  In the chronograph function, the measurement unit 111 measures the elapsed time from the time when the measurement start is instructed (the time when the operation input related to the measurement start is received). For example, the measurement unit 111 measures the total time (total elapsed time) that is the elapsed time from the time when the measurement start is instructed to the time when the measurement stop is instructed (when the operation input related to the measurement stop is received). .

  Further, the measurement unit 111 measures a split time (intermediate elapsed time) that is a predetermined intermediate elapsed time in a period from when the measurement start is instructed to before the measurement stop is instructed. For example, the measurement unit 111 measures the elapsed time from the time when the measurement start is instructed to the time when the split time (or lap time) is instructed (when the operation input related to split or lap is received) as the split time. To do. In addition, the measurement unit 111 is based on a plurality of measured split times (for example, based on the split time measured this time and the split time measured immediately before), and the elapsed time between predetermined different times during the measurement (for example, Then, a lap time is calculated which is an elapsed time between the time when the current split time is measured and the time when the immediately preceding prep time is measured. Note that the measuring unit 111 may measure the lap time instead of the split time.

  The control unit 112 causes the storage unit 103 to store measurement data indicating the measurement time measured by the measurement unit 111. Here, the measurement data is, for example, data including a measurement time obtained by one measurement including the split time and the total time, that is, measurement from the measurement start to the measurement stop. Details of the configuration of the measurement data and details of processing performed by the processing unit 101 will be described later. For example, the control unit 112 stores the split time and the total time measured by the measurement unit 111 in a predetermined storage area in the storage unit 103 based on the operation input received by the operation input unit 102. Further, the control unit 112 causes the display unit 105 to display the measurement time measured by the measurement unit 111.

  The determination unit 113 detects a storable free space in the storage capacity of the storage unit 103 and determines whether or not the predetermined free space is exceeded. The determination unit 113 may be included in the control unit 112.

  The operation input unit 102 includes buttons A to D (see FIG. 1) and receives operation inputs related to time setting, a chronograph function, and the like. Then, the operation input unit 102 supplies an instruction (operation signal) corresponding to the operation input received by each button A to D to the processing unit 101.

For example, an example of the function of each button A to D when the electronic timepiece 10 is set to a chronograph measurement mode (the details of the operation mode will be described later with reference to FIG. 4), which is an operation mode for executing the chronograph function. Is shown below.
Button A: Button for receiving an instruction to switch the operation mode Button B: Button for receiving an instruction to turn on the backlight (light emitting unit 106) Button C: Button for receiving an instruction to start (measurement start) / stop (measurement stop) -Button D: Button for accepting an instruction to lap (measure the elapsed time) / reset

  The storage unit 103 stores measurement data indicating the measurement time measured by the measurement unit 111 of the processing unit 101. For example, the storage unit 103 stores this measurement data in a predetermined storage area.

  The oscillating unit 104 includes, for example, a crystal oscillator, generates an oscillation signal having a predetermined frequency (for example, 32768 Hz), divides the generated oscillation signal (for example, 100 Hz), and generates a timing signal as a timing reference. Generate. Then, the oscillation unit 104 supplies the generated timing signal to the processing unit 101.

The display unit 105 is, for example, a liquid crystal display (LCD (Liquid Crystal).
Display)), and the current time and measurement time measured by the measurement unit 111 are displayed.
The light emitting unit 106 is, for example, a backlight installed on the back surface of the display unit 105, and emits light when a light emission instruction signal indicating that the display unit 105 emits light is supplied from the processing unit 101. Make displayed characters, symbols, figures, etc. visible in the dark. Note that the processing unit 101 supplies a light emission instruction signal to the light emitting unit 106 based on an operation input received by the operation input unit 102 (for example, an operation input to the button B).

  The power supply unit 107 includes, for example, a battery, and includes each unit included in the electronic timepiece 10, such as the processing unit 101, the operation input unit 102, the storage unit 103, the oscillation unit 104, the display unit 105, the light emitting unit 106, and the like. Supplies power to operate. Note that the battery may be either a primary battery or a secondary battery, or may include a solar battery.

(Details of operation mode)
Next, with reference to FIG. 3, the operation mode and transition of the operation mode of the electronic timepiece 10 will be described.
FIG. 3 is a diagram illustrating an example of the transition of the operation mode of the electronic timepiece 10 in the present embodiment.
As shown in the figure, the electronic timepiece 10 has five operation modes: a time display mode 41, a chronograph measurement mode 42, a data display mode 43, a timer measurement mode 44, and an alarm setting mode 45. When the button A that accepts an instruction to switch the operation mode is pressed, the electronic timepiece 10 changes the operation mode in the order of the time display mode 41, the chronograph measurement mode 42, the data display mode 43, the timer measurement mode 44, and the alarm setting mode 45. Switch sequentially.

At the first activation of the electronic timepiece 10, the processing unit 101 sets the operation mode to the time display mode 41.
The time display mode 41 is an operation mode for measuring and displaying the current time (current time). However, the processing unit 101 counts the peak of the amplitude of the timing signal input from the oscillation unit 104 regardless of the operation mode (pulse count), and counts the current time. The electronic timepiece 10 may display the current date and day of the week in the time display mode 41.
Further, when the button A is pressed in the time display mode 41, the processing unit 101 changes the operation mode to the chronograph measurement mode 42.

The chronograph measurement mode 42 is an operation mode in which time is measured and recorded by the chronograph function. The processing unit 101 measures the elapsed time (split time, total time, etc.) from the start of measurement and displays it on the display unit 105 in accordance with the operation input to the buttons B and C of the operation input unit 102, and displays the measurement. Data is stored in the storage unit 103. Details of the state transition of the chronograph measurement operation in the chronograph measurement mode 42 will be described later with reference to FIG.
In addition, when the button A is pressed in the chronograph measurement mode 42, the processing unit 101 changes the operation mode to the data display mode 43.

The data display mode 43 is an operation mode for displaying the instructed measurement time on the display unit 105 among the measurement time (measurement data) stored in the storage unit 103. In the data display mode 43, the processing unit 101 reads the split time (or lap time) from the storage unit 103 in accordance with an operation input to the operation input unit 102, and calculates the “last lap time” calculated based on the read split time. (Or the read “last lap time”) is displayed on the display unit 105. If there is no “previous lap time” in the storage unit 103, the processing unit 101 reads the split time (or lap time) stored (saved) last in the storage unit 103 and reads the read split time or lap time. May be displayed on the display unit 105. Further, the processing unit 101 reads the previously measured total time or the selected total time from the storage unit 103 in accordance with an operation input to the operation input unit 102 and causes the display unit 105 to display the read total time.
In addition, when the button A is pressed in the data display mode 43, the processing unit 101 changes the operation mode to the timer measurement mode 44.

The timer measurement mode 44 is an operation mode in which the remaining time until the count is zero is displayed on the display unit 105 by counting down from the set timer time, and an alarm sound is generated based on the count zero timing.
In addition, when the button A is pressed in the timer measurement mode 44, the processing unit 101 changes the operation mode to the alarm setting mode 45.

The alarm setting mode 45 is an operation mode in which an alarm sound is sounded when the current time measured reaches a set alarm time.
Further, when the button A is pressed in the alarm setting mode 45, the processing unit 101 changes the operation mode to the time display mode 41.

(State transition of measurement operation in chronograph measurement mode 42)
Next, details of the state transition of the measurement operation in the chronograph measurement mode 42 will be described with reference to FIG. FIG. 4 is a diagram illustrating an example of state transition in the chronograph measurement mode 42.

  When the operation mode is first shifted to the chronograph measurement mode 42, the processing unit 101 first sets the reset state 51 (measurement stop state) in which measurement is not started. When the button C is pressed in the reset state 51, the processing unit 101 makes a transition to the measurement state 52 and starts measuring the elapsed time from when the button C is pressed. In addition, the processing unit 101 causes the display unit 105 to display the measured elapsed time (split time) in the measurement state 52.

  Next, when the button D is pressed in the measurement state 52, the processing unit 101 makes a transition to the lap display state 53. In the lap display state 53, the processing unit 101 stores (saves) the split time at the time when the button D is pressed in the storage unit 103, and calculates the lap time based on the split time at the time when the button D is pressed. Is displayed on the display unit 105. In addition, when a predetermined time (for example, 10 seconds) elapses in the lap display state 53, the processing unit 101 returns to the measurement state 52.

  The processing unit 101 makes a transition to the lap display state 53 each time the button D is pressed in the measurement state 52, and stores (saves) the split time at the time when the button D is pressed in the storage unit 103 each time the button D is pressed. And the calculated lap time is displayed on the display unit 105.

  Further, when the button C is pressed in the measurement state 52, the processing unit 101 makes a transition to a stop state 54 in which the chronograph measurement operation is temporarily stopped. In the stop state 54, the processing unit 101 temporarily stops the measurement of the elapsed time that started measurement when the button C was pressed in the reset state 51. Note that when the button C is pressed in the stop state 54, the processing unit 101 makes a transition to the measurement state 52 and resumes the temporarily stopped measurement.

  When the button D is pressed in the stop state 54, the processing unit 101 stores the measurement time that is temporarily stopped (the split time when the button C is finally pressed in the measurement state 52) as a total time. The information is stored (saved) in 103 and transitioned to the reset state 51. In this reset state 51, the processing unit 101 updates the measurement time (split time) to zero (reset).

  As a result, the processing unit 101 completes the storage of the measurement data (split time, total time) for one time in the storage unit 103. That is, the split time and the total time are stored in the storage unit 103 as measurement data for each measurement. The split time is stored only the number of laps (split time measurement) after the start of measurement, that is, the number of times the button D is pressed. If the button D is not pressed once after the measurement is started, the measurement data does not include the split time.

  In addition, when the processing unit 101 is already measuring with the chronograph function (measurement state 52, lap display state 53, or stop state 54) and changes the operation mode, the processing unit 101 displays the operation state under measurement. Let it continue. For example, in the measurement state 52, the processing unit 101 continues the measurement state 52 when the operation mode is changed, and continues the operation of the measurement state 52 when the operation mode is changed to the chronograph measurement mode 42 again. And

(Description of memory area where measurement data is stored)
Next, a memory area of the storage unit 103 in which measurement data is stored will be described.
FIG. 5 is a diagram illustrating an example of a memory area of the storage unit 103 in the present embodiment.

  In the memory area of the storage unit 103, for example, one continuous area (referred to as a memory area MS) is predetermined as a memory area for storing measurement data. The processing unit 101 sequentially adds measurement data measured by the chronograph function (a series of measurement data including a split time and a total time measured from the measurement start to the measurement stop) sequentially in the memory area MS every time measurement is performed. And memorize it. For example, as illustrated in FIG. 5, the processing unit 101 measures measurement data (measurement data (1), measurement data (2),..., Measurement according to the measurement order (first measurement to n-th measurement). Data (n)) is added to the memory area MS of the storage unit 103 (the memory area MS is written in order and stored).

  Here, in the electronic timepiece 10 (for example, a wristwatch) having a chronograph function, downsizing and low power consumption are desired. Therefore, the chronograph can be efficiently processed with a small amount of resources (CPU processing capacity and memory capacity). A measurement process is performed. For this reason, in the electronic timepiece 10, the memory capacity of the memory area MS is not infinitely large, but is limited to a capacity that can be mounted and processed (for example, about 300 pieces of split time data). Storage capacity).

  Further, for example, the processing unit 101 stores the split time in the storage unit 103 every time the button D (lap) is pressed, and the button D (reset) is pressed after the button C (stop, measurement stop) is pressed. The total time is stored in the storage unit 103 when the button is pressed. That is, the processing unit 101 performs processing such that the measured split time and total time are collectively stored in the storage unit 103 in one measurement, and the storage unit 103 stores the measurement result at each measurement event occurrence timing. It is made to process with small electric power by memorize | storing in.

(Configuration of measurement data)
FIG. 6 is a diagram illustrating an example of a configuration of measurement data. In the example shown in this figure, the measurement data has items of header information (mark, date), split time, and total time. When the button C (start, measurement start) is pressed in the reset state 51, the processing unit 101 stores the header information following the area in the memory area MS where the immediately previous measurement data is stored. Here, the “mark” is information (for example, a number) for identifying each measurement data (measurement data for one time from the start of measurement to the stop of measurement). “Date” is information indicating the date on which the measurement was performed.

  Next, when the button D (lap) is pressed in the measurement state 52, the processing unit 101 adds the split time at the time of pressing to the memory area after the header information. As shown in this figure, each time the button D (lap) is pressed in the measurement state 52, the processing unit 101 sequentially calculates the split time (split time 1, split time 2, split time 3,...). I will add.

  In addition, when the button C (stop, measurement stop) is pressed in the measurement state 52 and the transition to the stop state 54 is made, and then the button D (reset) is pressed in the stop state 54, the processing unit 101 sets the total time immediately before. Append to the memory area after the split time stored in.

  In this way, the processing unit 101 adds header information, split time, total time, and the like to the limited memory area MS in the storage unit 103 at every measurement event occurrence timing.

(Processing when the free space of the memory area MS is small)
Next, in the electronic timepiece 10, a measurement data storing process when the free space in the memory area MS is reduced will be described.

  If there is no free space in the memory area MS during measurement, the split time and total time to be measured after that cannot be stored in the storage unit 103, so that the processing unit 101 does not have free space in the memory area MS during measurement. Is reduced, the saving of the split time measured thereafter is limited so that at least a capacity capable of storing the total time is left in the memory area MS. That is, the control unit 112 of the processing unit 101 gives priority to the total time over the split time measured immediately before the split time (intermediate elapsed time) based on the storable free space of the storage unit 103. 103.

  For example, the control unit 112 stores the split time measured by the measuring unit 111 in the storage unit 103 (memory area MS) in response to an instruction to measure the split time (halfway elapsed time). In addition, when the free space that can be stored in the storage unit 103 (memory area MS) is smaller than the combined capacity of the capacity for storing the split time and the capacity for storing the total time, the control unit 112 stores the split time in the storage unit 103. It is not stored in (memory area MS). And the control part 112 memorize | stores total time in the memory | storage part 103 (memory area | region MS), after measurement stop is instruct | indicated.

  Here, when the free space that can be stored in the storage unit 103 (memory area MS) is smaller than the combined capacity of storing the split time and the capacity of storing the total time, the control unit 112 determines the next split time. Is stored when the capacity for storing the total time is insufficient. As an example, if each of the split time and the total time is 4 bytes of data, the free capacity is less than 8 bytes (capacity of less than 8 bytes), which is the combined capacity of the split time and the total time, for example, This is a case of a capacity of 7 bytes or less.

  For example, in the memory area MS shown in FIG. 5 described above, during measurement of the measurement data (n), the free area (free area ML) of the memory combines the capacity for storing the split time and the capacity for storing the total time. It is assumed that the capacity becomes smaller than the capacity (hereinafter also referred to as capacity Mth1). At this time, the measurement data (n) is in a state where, for example, up to split time 3 is additionally written and stored in the memory area MS as shown in FIG. FIG. 7 shows that when the split time 3 is stored in the memory area MS during the measurement of the measurement data (n), the free area ML can store only the subsequent measurement time (split time or total time). It is a figure showing that it is a large capacity (less than capacity Mth1).

  In this case, as shown in FIG. 7, when the button D is pressed for the fourth time (the lap button is pressed for the fourth time), the processing unit 101 measures the split time and displays the lap time, but the free area ML has the capacity Mth1. Therefore, the measured split data is not saved (added to the measurement data (n)). Even if the button D is pressed after the fifth time, the processing unit 101 can store the total time without saving the measured split data (addition to the measurement data (n)). A free area ML is left as a new area.

  Then, as illustrated in FIG. 8, when the button C (stop, measurement stop) is pressed in the measurement state 52 and the transition is made to the stop state 54, and then the button D (reset) is pressed in the stop state 54, the processing unit 101 (control unit 112) stores the measured total time in the empty area ML (added to measurement data (n)).

(Explanation of measurement data saving process)
Next, with reference to FIG. 9, the operation of the measurement data saving process when the free space of the memory area MS in the electronic timepiece 10 is small will be described. FIG. 9 is a flowchart illustrating an example of a measurement data storage process according to the present embodiment.

  When the operation mode of the electronic timepiece 10 is set to the chronograph measurement mode 42, the processing unit 101 activates the chronograph measurement mode 42 in the reset state 51. Then, the processing unit 101 determines whether or not the button C (start) is pressed based on the operation signal supplied from the operation input unit 102 (step S101). In step S101, when it is determined that the button C (start) is not pressed (step S101: NO), the processing unit 101 continues the reset state 51 and repeats the process of step S101.

  In step S101, when it is determined that the button C (start) is pressed (step S101: YES), the processing unit 101 makes a transition from the reset state 51 to the measurement state 52. That is, the measurement unit 111 starts chronograph measurement (elapsed time from when the button C is pressed) (step S102).

  Next, the processing unit 101 determines whether or not the button C (stop) is pressed based on the operation signal supplied from the operation input unit 102 (step S103).

  When it is determined in step S103 that the button C (stop) is not pressed (step S103: NO), the processing unit 101 determines whether or not the button D (lap) is pressed (step S111). When it is determined in step S111 that the button D (lap) is not pressed (step S111: NO), the processing unit 101 returns the process to step S103 and continues the measurement state 52.

  In step S111, when it is determined that the button D (lap) is pressed (step S111: YES), the processing unit 101 makes a transition from the measurement state 52 to the lap display state 53. First, the measuring unit 111 measures the split time up to the point when the button D (lap) is pressed (step S112). Next, the determination unit 113 can store the free space that can be stored in the storage unit 103 (memory area MS) based on the combined capacity (Mth1) of the capacity for storing the split time measured in step S112 and the capacity for storing the total time. It is determined whether (the capacity of the free area ML) is small (whether the capacity of the free area ML is less than the capacity Mth1) (step S113). When it is determined in step S113 that the capacity of the free area ML is equal to or larger than the capacity Mth1 (step S113: NO), the control unit 112 stores the split time measured in step S112 in the storage unit 103 (memory area MS). Store and save (step S114). And the process part 101 advances a process to step S115.

  On the other hand, when it is determined in step S113 that the capacity of the free area ML is less than the capacity Mth1 (step S113: YES), the processing unit 101 performs the process of step S114 described above (a process for storing the split time). If not, the process proceeds to step S115. In other words, the control unit 112 uses the determination unit 113 to determine the free space (free space) that can be stored in the storage unit 103 (memory area MS) from the combined capacity (Mth1) of the capacity for storing the split time and the capacity for storing the total time. When it is determined that the capacity of the area ML is small, the split time is not stored in the storage unit 103.

  In step S115, the measurement unit 111 calculates a lap time based on the measured split time. Further, the control unit 112 causes the display unit 105 to display the lap time calculated by the measurement unit 111. Note that the processing unit 101 returns (transitions) to the measurement state 52 after a predetermined time (for example, 10 seconds) has elapsed since the transition to the lap display state 53. That is, the processing unit 101 returns the processing to step S103 after a predetermined time (for example, 10 seconds) has elapsed since the transition to the lap display state 53.

  On the other hand, when it is determined in step S103 that the button C (stop) is pressed (step S103: YES), the processing unit 101 makes a transition from the measurement state 52 to the stop state 54. The measuring unit 111 suspends the measurement of the elapsed time and measures the split time until the button C (stop) is pressed. Further, the control unit 112 causes the display unit 105 to display the split time measured by the measurement unit 111 (step S121).

  Next, the processing unit 101 determines whether or not the button C (start) is pressed based on the operation signal supplied from the operation input unit 102 (step S122). If it is determined in step S122 that the button C (start) has been pressed (step S122: YES), the process returns to step S102, and the measurement unit 111 resumes the measurement that has been temporarily stopped.

  If it is determined in step S122 that the button C (start) is not pressed (step S122: NO), the processing unit 101 determines whether the button D (reset) is pressed (step S123). ). If it is determined in step S123 that the button D (reset) has not been pressed (step S123: NO), the processing unit 101 returns the process to step S122.

  On the other hand, when it is determined in step S123 that the button D (reset) is pressed (step S123: YES), the control unit 112 uses the split time (last split time) measured in step S121 as the total time. It memorize | stores and memorize | stores in the memory | storage part 103 (step S124). Then, the processing unit 101 makes a transition from the stop state 54 to the reset state 51. As a result, the electronic timepiece 10 ends one chronograph measurement.

In this way, during the chronograph measurement, the processing unit 101 stores the split time so as to leave a memory area (memory capacity) capable of storing the total time based on the free capacity of the storage unit 103 (memory area MS). Limit. Then, the processing unit 101 stores the total time in the remaining memory area and ends the measurement. That is, the control unit 112 of the processing unit 101 gives priority to the total time over the split time measured immediately before the split time (intermediate elapsed time) based on the storable free space of the storage unit 103. 103.
Thereby, the electronic timepiece 10 can prevent the total time of the measurement from being stored after the measurement is started by the chronograph function.

  For example, a user who uses the chronograph function has a purpose of recording his / her running data in running training, marathon competition, and the like. In addition, the user starts running and starts measuring with the chronograph function, and confirms the lap time by pressing the lap button at a predetermined point on the way from the start to the goal (confirmed by viewing the lap time display) ) While driving. As a result, the user grasps the driving situation by comparing the estimated elapsed time with the actual elapsed time, and the total time until finally reaching the goal matches the target time. Adjust the running pace to In addition, since the user can check the measured travel data again after the measurement is completed, the user can also use the data for the next training and target management of the competition.

  Thus, the user who uses the chronograph function is used for the purpose of confirming the split time or lap time at a predetermined point during the measurement. On the other hand, after the measurement is finished, the user may use any of the intermediate split time or lap time and the final time of the final result. In such a case, it is desirable that the total time of the final result can be confirmed rather than the split time or lap time in the middle.

Therefore, according to the electronic timepiece 10 of the present embodiment (first embodiment), when the storable free capacity is insufficient, the final time total time is stored with priority over the intermediate split time or lap time. Therefore, the convenience for the user can be improved.
That is, according to the present embodiment, convenience can be improved in an electronic timepiece having a chronograph function.

[Second Embodiment]
Next, the electronic timepiece 10 of the second embodiment will be described. In the second embodiment, when the free space in the memory area MS is reduced, the processing method for storing the total time in the storage unit 103 in preference to the split time is different from that in the first embodiment described above. To do. The measurement data storing process according to the second embodiment will be described with reference to FIG.

  FIG. 10 is a diagram illustrating an example of measurement data storage processing according to the second embodiment. 10, parts corresponding to those in FIGS. 7 and 8 are given the same reference numerals. Also, in FIG. 10, an area shown as the empty area ML is an area corresponding to the empty area ML shown in FIG. 7, and is an area in which one measurement time for writing the total time can be written last (last 1), the measurement data can be written in one area.

  As described above, in the example of processing shown in FIG. 7, up to split time 3 is additionally recorded and stored in the memory area MS, and when the fourth button D is pressed (fourth lap button is pressed), split time 4 is measured. The time is not stored and is left as a free area ML. On the other hand, in the second embodiment, as shown in FIG. 10A, when the button D is pressed for the fourth time (the lap button is pressed for the fourth time), the processing unit 101 (the control unit 112) causes the split time. 4 is stored in the free space ML. Thereby, the capacity of the free area ML is smaller than the capacity for storing one measurement time (hereinafter also referred to as capacity Mth2).

  Next, when the button D is pressed for the fifth time, the processing unit 101 (control unit 112) stores the split time 5 overwriting the split time 4 because the free space ML is less than the capacity Mth2 ( (Refer FIG.10 (b)). When the button D is further pressed, the processing unit 101 (control unit 112) repeats the split time 6 overwriting the split time 5, the split time 7 overwriting the split time 6, and so on. That is, when the free space is insufficient, the processing unit 101 (control unit 112) overwrites the split time stored immediately before.

  Then, it is assumed that after the button C (stop, measurement stop) is pressed in the measurement state 52 and transitioned to the stop state 54, the button D (reset) is pressed in the stop state 54. In this case, since the free space ML is less than the capacity Mth2, the processing unit 101 (control unit 112) overwrites and stores the measured total time in the split time stored immediately before (see FIG. 10C). ).

  Next, with reference to FIG. 11, the operation of the measurement data saving process when the free space in the memory area MS in the electronic timepiece 10 of the second embodiment is small will be described. FIG. 11 is a flowchart illustrating an example of measurement data storage processing according to the second embodiment. Here, the processes shown in FIG. 11 are different from the processes shown in FIG. 9 in the processes in steps S213, S214, S215, and S215 and the processes in steps S224, S225, and S226. In FIG. 11, processes corresponding to the processes in FIG. 9 are denoted by the same reference numerals, and description thereof is omitted.

  First, the operation of the process when the button D (lap) is pressed in the measurement state 52 (that is, the process of storing the split time) will be described. In step S111, when it is determined that the button D (lap) is pressed (step S111: YES), the processing unit 101 makes a transition from the measurement state 52 to the lap display state 53. The measuring unit 111 measures the split time until the button D (lap) is pressed (step S112).

  The determination unit 113 determines whether or not the free space (capacity of the free area ML) that can be stored in the storage unit 103 (memory area MS) is smaller than the capacity (Mth2) for storing the split time measured in step S112 (free space area). It is determined whether or not the ML capacity is less than the capacity Mth2 (step S213). When it is determined in step S213 that the capacity of the free area ML is equal to or larger than the capacity Mth2 (step S213: NO), the control unit 112 stores the split time measured in step S112 in the storage unit 103 (memory area MS). Add and save (step S214). And the process part 101 advances a process to step S115.

  On the other hand, when it is determined in step S213 that the capacity of the free area ML is less than the capacity Mth2 (step S213: YES), the control unit 112 uses the split time measured in step S112 as the storage unit 103 (memory area The split time stored immediately before (MS) is overwritten and saved (step S215). And the process part 101 advances a process to step S115.

  Next, an operation of a process when the button D (reset) is pressed in the stop state 54 (that is, a process for storing the total time) will be described. In step S123, it is determined that the button D (reset) is pressed (step S123: YES). In this case, the determination unit 113 uses the capacity (Mth2) for storing the split time (that is, the total time) measured in step S121 to store the free space (capacity of the free area ML) in the storage unit 103 (memory area MS). ) Is small (whether the capacity of the free area ML is less than the capacity Mth2) (step S224).

  When it is determined in step S224 that the capacity of the free area ML is equal to or greater than the capacity Mth2 (step S224: NO), the control unit 112 sets the split time (last split time) measured in step S121 as the total time. Then, it is added and stored in the storage unit 103 (memory area MS) (step S225).

  On the other hand, when it is determined in step S224 that the capacity of the free area ML is less than the capacity Mth2 (step S224: YES), the control unit 112 totalizes the split time (last split time) measured in step S121. As the time, the split time stored immediately before the storage unit 103 (memory area MS) is overwritten and saved (step S226). As a result, the electronic timepiece 10 ends one chronograph measurement.

  As described above, the control unit 112 stores the split time measured by the measurement unit 111 in response to the instruction to measure the split time (intermediate elapsed time) in the storage unit 103 and the capacity for storing the split time. When the free space that can be stored in the storage unit 103 is smaller, the split time is overwritten and stored in the split time stored immediately before. In addition, when the control unit 112 stores the total time in the storage unit 103 and the storable free capacity of the storage unit 103 is less than the capacity for storing the total time, the split in which the total time is stored immediately before Overwrite the time and memorize it.

That is, the control unit 112 causes the storage unit 103 to store the total time in preference to the split time measured immediately before the split time (intermediate elapsed time) based on the free space that can be stored in the storage unit 103. .
Thereby, the electronic timepiece 10 can prevent the total time of the measurement from being stored after the measurement is started by the chronograph function. That is, according to the second embodiment, convenience can be improved in an electronic timepiece having a chronograph function.

  10 and 11, the control unit 112 overwrites the split time stored immediately before the split time when the free space that can be stored in the storage unit 103 is less than the capacity for storing the split time. Although the process to memorize | store was demonstrated, it is not restricted to this. For example, when the storage unit 103 has less free space that can be stored than the capacity for storing the split time, the control unit 112 does not store the split time, and overwrites only the total time with the last stored split time. It may be memorized.
