Description

  The present invention relates to an analog timepiece with a timekeeping function.

In recent years, not only digital electronic timepieces but also analog electronic timepieces (pointer-type electronic timepieces) have been strongly requested to add multi-functions such as chronographs, alarms, timers, etc., especially chronographs (stopwatches) and Analog watches having a timekeeping function such as a timer have been commercialized.
In such an analog timepiece with a timekeeping function, in addition to time indication hands (basic timepiece hands) such as hour hand, minute hand, second hand, etc., a sub time hand for measuring time display can be placed at any position on the dial, for example, Dedicated small windows are provided and set at positions of 3 o'clock, 6 o'clock, and 9 o'clock (see, for example, Patent Document 1).
And the motor which drives the subneedle of each small window was each provided, and each subneedle was driven independently. In other words, one sub-needle is provided at each of the 3 o'clock, 6 o'clock, and 9 o'clock positions, and each sub-needle displays the hour, minute, and second of the elapsed time in order to measure the elapsed time in the timer function or the like. Assigned for display.

Japanese Patent No. 2600132

  However, in the analog timepiece with the timekeeping function, since the indicator hands for displaying the hour, minute, and second are located apart and not on the same axis, it is difficult for the user to recognize the elapsed time sensuously. There was a problem.

On the other hand, a plurality of, for example, two needles are arranged coaxially as the secondary needles, and these two secondary needles are driven by one motor to display the elapsed time hour / minute, What is displayed is also commercialized.
Such a display needle (sub-needle) on the same axis has an advantage that the user can easily perceive the elapsed time.

However, since the plurality of display hands provided on the same axis are interlocked with a gear, there is a limitation in time display, and there is a problem that the maximum value of the measurement time cannot be arbitrarily set. For example, when two indicator hands for displaying the hour and minute are provided on the same axis, the long hand usually displays 60 minutes per revolution and the short hand displays 12 hours per revolution.
That is, when two display hands are provided on the same axis, the number of the long hands is set to 60 divisions and the length of the short hands is set to 720 divisions (60 × 12). This is a basic setting for the time display of the timepiece. For example, in a multi-function timepiece, when two hands provided on the same axis also serve as an alarm setting time display, the relationship between the two hands is set. Cannot be changed arbitrarily.
For this reason, for example, when the minute / second display is performed with two display hands on the same axis, the long hand displays 60 seconds in one lap and the short hand displays 12 minutes in one lap. Limited to a maximum of 12 minutes. For this reason, when the elapsed time is 12 minutes or more, the display hand becomes one round or more. For example, there is a problem that it is not possible to determine whether the elapsed time is 13 minutes or 1 minute simply by looking at the display hand.

  An object of the present invention is to provide an analog timepiece having a timekeeping function that can display a measurement time in an easy-to-understand manner and can arbitrarily set a maximum value of the measurement time at a design stage.

The present invention includes an external operation member,
Instructed to start and stop time measurement by the external operation member,
A time measuring means for measuring time according to the instruction;
An analog timepiece with a timekeeping function, comprising a first display means and a second display means for displaying the measurement time measured by the timekeeping means,
The measurement time measured by the time measuring means is represented by at least a first time unit and a second time unit that is a time unit shorter than the first time unit,
The first display means includes a first motor, a first sub-needle and a second sub-needle driven by the first motor,
The second display means includes a second motor and a third auxiliary needle driven by the second motor,
The first sub-needle and the third sub-needle are configured to be able to display a first time unit of the measurement time, and the second sub-needle is configured to be able to display a second time unit of the measurement time,
The third sub needle has a rotation range within one rotation (or 360 degrees) of the third sub needle for a measurement time T2 longer than the measurement time T1 measured when the first sub needle rotates once. together they are configured to be displayed in, wherein the said rotation range of the third sub-needle, characterized that you length of the scale corresponding to the measured time T2 is provided.

In the present invention, the time is measured by the time measuring means, and the measured time is displayed by the first display means and the second display means. At this time, the first display means includes a first sub-needle and a second sub-needle driven by the first motor, and each sub-needle has a first time unit (for example, minute) and a second time unit for measuring time. Since (for example, seconds) is displayed, the display can be the same as that of a normal clock, the measurement time can be displayed in an easy-to-understand manner, and the user can intuitively and easily grasp the measurement time.
In addition, since the first display unit moves the two hands in conjunction with one motor, the time display is limited as described above. That is, when displaying the hour with the first sub-hand and displaying the minute with the second sub-hand as in the case of displaying the alarm time on the first display means, When the minute is displayed with one sub-needle and the second is displayed with the second sub-needle, the measurement time of 12 minutes is displayed when the first sub-needle makes one round. For this reason, when the time is 12 minutes or longer, the first sub-needle rotates one or more rounds, so the user cannot determine whether the measurement time is less than 12 minutes or 12 minutes or more, and the maximum value of the measurement time. Is limited to 12 minutes.
On the other hand, in the present invention, the same time unit as the first sub-needle is displayed by the third sub-needle, and the third sub-needle is shorter than the measurement time T1 when the first sub-needle rotates once. Since the long measurement time T2 can be displayed, the correct measurement time can be grasped by referring to the third sub-needle even when the first sub-needle moves one or more rounds. And since this 3rd sub needle | hook is provided independently, the measurement time when the 3rd sub needle | hook makes 1 round can also be set freely, and the maximum value of measurement time can be set arbitrarily in a design stage.

(Claim 2)
In the present invention, the first time unit is minutes, the second time unit is seconds, the first sub-hand displays the minutes of the measurement time, and the second sub-hands are seconds of the measurement time. It is preferable that the third sub-hand displays the measurement time.

According to the present invention, since the first time unit is minutes and the second time unit is seconds, the minute and second of the measurement time can be displayed with the first and second sub hands of the first display means. Can easily grasp the measurement time to the second.
In the present invention, the first time unit may be “hour” and the second time unit may be “minute”.

(Claim 3)

The second sub-hand displays the second of the measurement time, the third sub-hand displays the minute of the measurement time, and when the measurement time is 1 hour or more, the first time unit is the hour. The second time unit is minutes, the first sub-hand displays the time of the measurement time, the second sub-hand displays the measurement time, and the third sub-hand is the It is preferable to display the time of measurement time.

  According to the present invention, when the elapsed time is less than 1 hour and it is not necessary to display “hour” data as a time unit, minutes and seconds are displayed. When the elapsed time is 1 hour or more, Since the hour and minute are displayed, an appropriate display unit can be displayed with each sub-needle according to the elapsed time. Therefore, the elapsed time can be displayed appropriately, and the user can accurately grasp the elapsed time and improve convenience.

(Claim 4)
In the present invention, it is preferable that when the measurement time is 1 minute or less, the third sub-needle displays a second of the measurement time.
When the measurement time becomes 1 minute or less, the user can easily grasp the second display if the third sub-needle is switched from the display of “minute” of the measurement time to the display of “second”. For this reason, especially in the case of the timer display function that displays the measurement time in a countdown, “59 seconds, 58 seconds,... 1 second, 0 seconds” is displayed, so the user has finished measuring the set timer measurement time. It is possible to easily grasp when to do.

(Claim 5)
In the present invention, the first sub-needle and the second sub-needle are moved by the first motor as the measurement time elapses, and the third sub-needle is moved by the second motor. It is preferable that the hand is moved every minimum time interval of the first time unit.

For example, when the first time unit is “minute” and the second time unit is “second”, for example, the first sub-hand and the second sub-hand are stepped by the first motor in units of one second, and the third sub-hand The needle is stepped by the second motor every minute.
For this reason, the 2nd motor should just perform minimum operation | movement, and can implement | achieve energy saving. In addition, since the first sub-needle and the third sub-needle are moved synchronously, the user can easily grasp that the first sub-needle and the third sub-needle display the same first time unit.

The first switch detection unit 32 detects the pressing operation of the first button 6 and outputs a detection signal to the function processing unit 34 when the pressing operation is performed.
The second switch detection unit 33 detects the pressing operation of the second button 7 and outputs a detection signal to the function processing unit 34 when the pressing operation is performed.

The basic timepiece drive control unit 35 outputs a motor drive pulse using a reference signal (for example, a signal of 1 Hz) output from a reference signal generation circuit such as a crystal resonator, and an hour hand via the basic timepiece step motor 21. 11, the driving of the minute hand 12 and the small second hand 13 is controlled.
The mode display drive control unit 36 controls the driving of the mode display needle 14 via the mode display step motor 22.

The first motor drive control unit 37 controls the driving of the first sub needle 15 and the second sub needle 16 via the first step motor 23. In the present embodiment, among the secondary needles 15 and 16, the second secondary needle 16 that is a long needle is set to 60 divisions per revolution, and the first secondary needle 15 that is a short needle is set to 720 divisions per revolution, Driven in conjunction with each other.
The second motor drive control unit 38 controls the drive of the third auxiliary needle 17 via the second step motor 24. In the present embodiment, the third auxiliary needle 17 is set to 300 divisions per round.

The function processing unit 34 processes various functions in the analog timepiece 1 with a timekeeping function. In this embodiment, a time display processing unit 341, a timer processing unit 342, a chronograph processing unit 343, an alarm processing unit 344, and a local time display processing unit 345 are provided.
And if the mode switching operation by the crown 5 and the 1st button 6 is performed, the function process part 34 will switch a process mode sequentially, and will perform each process part 341-345 with the selected mode.

The time display processing unit 341 is operated when a time mode (TIME) is selected, and uses the first motor driving control unit 37 to make the hour hand 11 and the minute hand 12 with the first sub-hand 15 and the second sub-hand 16. The same time as the current time indicated by is displayed.
The timer processing unit 342 is operated when the timer mode (TMR) is selected, and uses the first motor drive control unit 37 and the second motor drive control unit 38 to make the first sub needle 15 and the second sub needle 16. The timer process is performed by the third sub needle 17. In the timer process, when a timer measurement time (for example, 10 minutes) is first set and a timer start operation is performed, each sub-needle 15 to 17 is rotated counterclockwise with the elapsed time, and the remaining time. (Timer remaining time) is displayed in real time. For this reason, the timer processing unit 342 includes an internal measurement counter that measures the timer time by counting the reference signal.

The chronograph processing unit 343 is operated when the chronograph mode (CHR) is selected, and uses the first motor drive control unit 37 and the second motor drive control unit 38, and uses the first sub needle 15 and the second sub drive unit 343. Chronograph processing is performed by the needle 16 and the third sub-needle 17. The chronograph process is a so-called stopwatch function. When a chronograph start operation is performed, the sub-hands 15 to 17 are rotated clockwise according to the elapsed time, and the elapsed time is displayed in real time. It is. For this reason, the chronograph processing unit 343 also includes an internal measurement counter that measures the elapsed time by counting the reference signal.
Therefore, the time measuring means of the present invention includes an internal measurement counter provided in the timer processing unit 342 and the chronograph processing unit 343.

  The alarm processing unit 344 is operated when the alarm mode (ALM) is selected, and uses the first motor drive control unit 37 to move the first sub needle 15 and the second sub hand 16 to set the alarm time. When the current time by the hour hand 11, the minute hand 12, and the small second hand 13 reaches the set alarm time, an alarm sound is generated.

  The local time display processing unit 345 is operated when the local time mode (LOC) is selected, and uses the first motor driving control unit 37 to move the hour hand 11, A time that differs from the current time displayed by the minute hand 12 by a preset time difference is displayed. For example, when traveling from Japan to a foreign country, the local time or the current time in Japan is displayed with the hour hand 11 and the minute hand 12, and the time in Japan or the local time is displayed with the first and second sub hands 15 and 16. Is displayed.

  Note that the mode switching operation using the crown 5 and the first button 6 is specifically performed by pressing the first button 6 in a state where the crown 5 is pulled out to the first stage. That is, each time the first button 6 is pressed with the crown 5 pulled out to the first stage, the function processing unit 34 sequentially switches the processing mode. With this mode switching operation, the function processing unit 34 operates the mode display drive control unit 36 to move the mode display needle 14 via the mode display step motor 22, and according to the selected mode, The mode indicator 14 indicates the time mode (TIME), timer mode (TMR), chronograph mode (CHR), alarm mode (ALM), or local time mode (LOC) displayed on the dial 2.

Here, the operation when the crown 5 and the buttons 6 and 7 are operated is as follows.
(Crown rotation function)
The rotation function of the crown 5 is the same as that of a general analog watch, and it is free even if it is rotated at the 0th stage, and the date correction (calendar correction) is performed by the rotation operation at the 1st stage, and at the 2nd stage. The hands of the basic timepiece of the hour hand 11, the minute hand 12, and the small second hand 13 are adjusted.

(Button operation function)
In the timer mode and the chronograph mode, when the first button 6 is pressed while the crown 5 is in the 0th stage, the time measurement is started and stopped alternately. Further, when the second button 7 is pressed while the crown 5 is at the 0th stage, the time measurement is reset. At this time, when the time measurement is reset in the chronograph mode, each of the secondary hands 15 to 17 returns to the 0 position. On the other hand, in the timer mode, the position may be returned to the 0 position at the time of the reset operation, but usually returns to the previously set timer measurement time.

  Further, when the crown 5 is pulled out to the first stage and the first button 6 is pressed, the mode switching process is performed as described above. On the other hand, when the crown 5 is pulled out to the first stage and the second button 7 is pressed in the timer mode, the alarm mode and the local time mode, the secondary hands 15 and 16 move in conjunction with each other, and the timer time, alarm time and local time The time is set.

[Timer processing]
Next, the operation when the timer mode is selected in the present embodiment will be described with reference to the flowcharts of FIGS.
In the present embodiment, the internal measurement counter of the timer processing unit 342 is configured to be able to measure up to 15 minutes as the maximum measurement time.
In the first display means, the second sub-needle 16 displays the elapsed time in seconds, and the first sub-needle 15 displays the elapsed time in minutes. The second sub-needle 16 makes a round and measures 1 minute, and the interlocked first sub-needle 15 makes a round and measures 12 minutes. For this reason, the scale 18 provided in the first display means divides one turn into 12 equal parts.

  In the second display means, the third sub-needle 17 displays the same elapsed time as the first sub-needle 15. However, the third sub-needle 17 is configured to be able to measure up to 15 minutes. For this reason, the scale 19 provided in the second display means divides one round into 16 and displays the scale from 0 to 15 minutes.

(Timer measurement time setting)
In the mode switching operation, when the timer mode is selected, a timer measurement time setting process is performed by a user operation.
Specifically, the timer processing unit 342 confirms whether the crown 5 is in the first stage (step S1), and if it is in the first stage, executes a timer measurement time setting process (step S2).

In the timer measurement time setting process S2, the timer processing unit 342 determines a signal from the second switch detection unit 33 as shown in FIG. 4, and determines whether or not the second button 7 has been pressed (step S21). ).
When the second button 7 is pressed, the timer measurement set time is added by 1 minute (step S22).

Along with the operation of the second button 7, the timer processing unit 342 drives the motors 23 and 24 via the first motor drive control unit 37 and the second motor drive control unit 38, and sets the time unit of “minute”. The designated first sub-needle 15 and third sub-needle 17 are advanced by 1 minute (step S23).
Specifically, when the second button 7 is pressed once, the second sub-needle 16 moves 60 steps (one turn) forward (clockwise) by the first step motor 23, and the second sub-needle 16 moves to the second sub-needle 16. The interlocking first sub needle 15 moves 60/720 steps (1/12 lap = 30 degrees) in the normal direction, and “1 minute 00 seconds” is set and displayed as the timer measurement time.
At the same time, the second step motor 24 causes the third sub-needle 17 to move forward by 1/16 rotation = 22.5 degrees, and the timer measurement time “1 minute” is also displayed on the third sub-needle 17.

Then, it is determined whether or not the crown 5 remains pulled out to the first stage (step S24). If it is pulled out to the first stage, the steps S21 to S23 are repeated. That is, when the user presses the second button 7 for a time that is desired to be set as the timer measurement time with the crown 5 pulled out to the first stage, the timer processing unit 342 repeats the steps S21 to S24, and the first sub-needle The timer measurement time set by the 15 and the third sub needle 17 is displayed.
FIG. 1 shows a state where the timer measurement time is set to 5 minutes.

In the present embodiment, the internal measurement counter of the timer processing unit 342 is set so as to be able to measure up to 15 minutes. For this reason, for example, when the second button 7 is pressed 13 times and the timer measurement time is set to “13 minutes”, the first sub-needle 15 is set to display 12 minutes in one round. The sub-needle 15 makes a full turn, and further rotates forward by 1 minute, and as shown in FIG. 6, the state is the same as when it is set at 1 minute 00 seconds.
On the other hand, the third sub-needle 17 of the second display means is set so as to be able to display up to 15 minutes. Therefore, when the timer measurement time is set to “13 minutes”, 13/16 rounds = 292.5 degrees Is moved forward and moved to a position indicating 13 minutes as shown in FIG.
For this reason, even if the first sub needle 15 and the second sub needle 16 of the first display means indicate 1 minute 00 seconds, the third sub needle 17 of the second display means indicates 13 minutes. The user can recognize that the timer measurement time is set to 13:00.

Therefore, when the timer measurement time reaches “15 minutes” by pressing the second button 7, the first sub-needle 15 and the second sub-needle 16 have the same instructions as in the case of 3 minutes 00 seconds, The 3 sub needles 17 indicate the position of 15 minutes.
When the timer measurement time reaches “15 minutes” and the second button 7 is further pressed, the timer measurement time returns to “0 minutes”. For this reason, when the timer measurement time is 15 minutes, the first sub needle 15 and the second sub needle 16 which have instructed 3 minutes 00 seconds return to the display of 0 minute 00 seconds, and the third sub hand 17 Also returns to the 0-minute display. Further, when the second button 7 is pressed, it can be set again every minute from the setting of 1 minute 00 seconds.

  As shown in FIG. 4, the setting of the above timer measurement time is continued until the crown 5 is moved to a position other than the first stage, usually the 0th stage, and the crown 5 is moved to a position other than the first stage, and in step S24. If it is determined as “No”, the timer measurement time setting process S2 is also ended.

(Timer measurement operation)
When the setting of the timer measurement time is finished, as shown in FIG. 3, the timer processing unit 342 determines whether the crown 5 has been returned to the 0th stage (step S3).
If crown 5 has been returned to the 0th stage in step S3, timer processing unit 342 is ready to perform timer measurement processing (step S4).

  In the timer measurement process S4, the timer processing unit 342 determines whether the first button 6 is first pressed as shown in FIG. 5 (step S41).

  When the first button 6 is pressed in step S41, the timer processing unit 342 starts timer measurement (step S42). When the timer measurement is started, the timer processing unit 342 starts to count down the measurement time, reverses the first step motor 23 via the first motor drive control unit 37, and the first sub-needle 15 and the second sub-needle 15. The auxiliary needle 16 is moved in the counterclockwise direction (reverse direction) to display the remaining time of the timer. For example, when the measurement is started with the timer measurement time set to 13 minutes, the first sub-needle 15 and the second sub-needle 16 are changed every 1 second from “13 minutes 00 seconds (display is 1 minute 00 seconds)”. “12 minutes 59 seconds, 58 seconds, 57 seconds...” And the remaining timer time (measurement time) are counted down and displayed.

  At the same time, the timer processing unit 342 reverses the second step motor 24 every one minute via the second motor drive control unit 38 in order to display the digit of the remaining timer time with the third auxiliary hand 17. For example, when the timer measurement time changes from “13 minutes 00 seconds” to “12 minutes 59 seconds”, the second sub-motor 17 is moved in reverse by the second step motor 24, and as shown in FIG. Move from the position indicating “12” to the position indicating “12 minutes”.

After the timer measurement is started, the timer processing unit 342 determines whether or not the remaining timer time has become 0 (step S43). If the remaining timer time is not 0, it is determined again whether the first button 6 has been pressed (step S44).
Then, the timer processing unit 342 continues to count down the measurement time until “Yes” is determined in any of steps S43 and S44, and the first sub needle 15 and the second sub needle 16 Continue to display. On the other hand, since the third auxiliary hand 17 indicates the digit of the remaining time of the timer, the third counter hand 17 reversely moves every time the remaining time of the timer changes, that is, every 1 minute.

  If the remaining time of the timer becomes 0 minute 00 seconds during the timer measurement (“Yes” in step S43), the timer processing unit 342 stops the timer measurement and indicates that the timer measurement has ended. Is notified by ringing (step S45).

  Further, when the first button 6 is pressed while the timer is being measured and the remaining timer time is not 0 minute 00 seconds, that is, when it is determined as “No” in Step S43 (“Yes” in Step S44). ), The timer processing unit 342 stops the timer measurement (step S46).

Next, in a state where the timer measurement is stopped, the timer processing unit 342 determines whether or not the second button 7 has been pressed (step S47). If the second button 7 has not been pressed, the timer processing unit 342 determines whether or not the crown 5 has been pulled out to the first stage (step S48).
If “No” is determined in step S48, the process returns to step S41 to determine whether the first button 6 is pressed again. Here, when the first button 6 is pressed again, the stopped timer measurement is resumed.
Therefore, the timer measurement is repeatedly started and stopped every time the first button 6 is pressed until the remaining time of the timer reaches 0:00.

If the second button 7 is pressed in step S47, the timer processing unit 342 resets timer measurement (step S49). Specifically, each sub-needle 15, 16, 17 is returned to the time position set in the timer measurement time setting process, and reset to a state where timer measurement is possible again. For example, if the set time of the timer measurement is 5 minutes 00 seconds, the timer remaining time is being displayed by each sub-needle 15, 16, 17 by the timer measurement, or 0 minutes 00 seconds after the timer measurement is completed. In any of the displayed states, when the reset operation is performed, the sub hands 15, 16, and 17 return to the display position of 5:00 seconds.
Therefore, when the first button 6 is pressed in step S41 after the timer reset (S49), the set timer measurement time can be measured again.

  On the other hand, if the first button 6 is not pressed in step S41, the timer measurement is stopped, so the process moves to the determination process in step S48, where it is determined whether the crown 5 has been pulled out to the first stage, If not pulled out, the process returns to the determination in step S41 again.

Further, when crown 5 is pulled out to the first stage in step S48, it is the case where the user resets the timer measurement time or the mode switching process, and therefore timer measurement process S4 is terminated. .
Then, as shown in FIG. 3, the timer processing unit 342 determines whether or not the timer mode is ended by the mode switching process (step S5), and when the timer mode is ended by the mode switching, the timer process is also ended. . On the other hand, if the timer mode has not ended, the timer processing unit 342 returns to step S1 and continues the process.

During the timer measurement, as described above, the third sub needle 17 displays the digits of the timer measurement time (timer remaining time) displayed by the first sub needle 15 and the second sub needle 16. However, when the remaining time of the timer becomes 1 minute or less, the third auxiliary hand 17 is set to the second of the timer measurement time (timer remaining time) displayed by the first auxiliary needle 15 and the second auxiliary needle 16. It is configured to display digits.
For example, as shown in FIG. 8, when the timer remaining time displayed by the first sub-needle 15 and the second sub-needle 16 is “0 minute 50 seconds”, the third sub-needle 17 is 60 on the outer periphery of the dial 2. “50 seconds” on the equally divided scale 20 is indicated. As a result, when the remaining timer time is less than 1 minute, the remaining seconds can be displayed with the third auxiliary hand 17 arranged at the center of the dial 2, so that the user can complete the timer measurement (timer remaining). The remaining time until the time becomes 0) can be clearly determined.

According to this embodiment, there are the following effects.
(1) Since the measurement time “minute (first time unit)” is displayed with the first sub needle 15 and the measurement time “second (second time unit)” is displayed with the second sub needle 16, As in a normal timepiece, “minute” and “second” can be displayed only by the first display means, the measurement time can be displayed in an easy-to-understand manner, and the user can also grasp the measurement time intuitively and easily.

(2) Further, the first display means makes the first sub-needle 15 make one turn for 12 minutes and turns for more than one turn for a measurement time of 12 minutes or more. ) Is difficult to grasp, but since the third sub-needle 17 that can be displayed for up to 15 minutes is provided, the third sub-needle 17 should be referenced even when the first sub-needle 15 has moved one or more rounds. Can grasp the correct measurement time. Therefore, the timer measurement time can be set in an easy-to-understand manner up to 15 minutes, so that it is possible to provide an optimum product specification for an application that requires 15-minute timer measurement in a yacht competition.

(3) Furthermore, since the third sub-needle 17 is independently moved by the second step motor 24, the measurement time when the third sub-needle 17 makes one revolution can be freely set, and the maximum value of the measurement time Can be set arbitrarily at the design stage. That is, in the above embodiment, the display can be made for up to 15 minutes. However, for example, the display can be made for up to 30 minutes or can be made for display for up to 60 minutes. can do.

(4) Further, when the timer measurement time becomes 1 minute or less, the third sub hand 17 is switched to the second display, so the third sub hand 17 having a larger length than the sub hands 15 and 16 is used to set the timer. The remaining number of seconds can be displayed, and the user can easily grasp when the measurement of the timer measurement time is completed.

(5) Since the third auxiliary hand 17 is moved at the minimum time interval corresponding to the first time unit, that is, every minute, the number of minutes of the current measurement time can be clearly displayed and the second step motor 24 may be driven at intervals of 1 minute, and energy saving can be realized.

(6) Since the first sub-needle 15 and the third sub-needle 17 are moved synchronously, the user displays the same first time unit as the first sub-needle 15 and the third sub-needle 17. Can be easily grasped.

(7) In addition to the first sub-needle 15, the third sub-needle 17 also displays “minute” data of the same measurement time, so the first sub-needle 15 overlaps the hour hand 11 and the minute hand 12, Even when the measurement time display by the one display means becomes difficult to recognize, the measurement time can be displayed by the third sub-needle 17. For this reason, regardless of the position of the hour hand 11 and the minute hand 12 at the current time, the user can always recognize the measurement time.

It should be noted that the present invention is not limited to the above-described embodiments, and modifications, improvements, and the like within the scope that can achieve the object of the present invention are included in the present invention.
For example, in the above-described embodiment, the timer function is described as the timekeeping function, but the present invention may be applied to a chronograph function (stopwatch function).
In the case of the stopwatch function, for example, “hour” is set as the first time unit and “minute” is set as the second time unit. In this case, the first sub needle 15 has a measurement time of 12 hours per round, but the third sub needle 17 can measure up to 15 hours.

In the initial state, as shown in FIG. 9, the first sub-needle 15 and the second sub-needle 16 are moved to the 0 o'clock position, and the third sub-needle 17 is moved to the 0 o'clock position for measurement. Start. After the measurement is started, the first sub needle 15 and the second sub needle 16 are moved forward to display the hour / minute of the measurement time, and the third sub hand 17 is also moved forward to display the time. For example, when 3 hours and 5 minutes have passed since the state of FIG. 9, the display is as shown in FIG. The hour hand 11 and the minute hand 12 also display the state of FIG. 9, that is, 13:14, 3 hours and 5 minutes have passed since 10: 9. Further, the third sub-hand 17 is moved every minimum time unit of “hour” which is the first time unit, that is, every hour.
Even when such a stopwatch function is executed, the same operational effects as the above-described embodiment can be obtained.

  In the above embodiment, the first sub-needle 15 continues to move after the measurement time reaches 12 minutes or more and rotates once. However, when the measurement time becomes 12 minutes or more, the first auxiliary needle 15 stops moving. May be set. According to such a configuration, when the first sub needle 15 is stopped, the user can grasp that the first sub needle 15 has made one round, that is, 12 minutes or more. What is necessary is just to confirm actual elapsed time with the subneedle 17.

  Furthermore, in the said embodiment, although the 3rd sub needle | hook 17 moved even when the measurement time was less than 12 minutes, when the measurement time was less than 12 minutes, the hand movement was stopped, and when it became 12 minutes or more. You may set so that a hand movement may be started. According to such a configuration, the user can grasp that the first sub-needle 15 has made one round, that is, 12 minutes or more when the third sub-needle 17 is moving. The actual elapsed time may be confirmed with the needle 17.

In the embodiment, the third sub-needle 17 is set to be measurable up to 15 minutes. However, since the third sub-needle 17 is driven independently by the second step motor 24, the maximum measurement time is It may be set freely at the design stage, not limited to 15 minutes.
Further, the maximum measurement time measured by the third sub needle 17 may be configured to be settable by the user. In this case, the scale 18 may be designed so as to be replaceable in accordance with the set maximum measurement time, or may be configured so that it can be read without expressing numbers.

When the measurement time is less than 1 hour, the first sub-needle 15 and the third sub-needle 17 display “minute” of the measurement time, and the second sub-needle 16 displays “second”. If the time is 1 hour or longer, the first sub-needle 15 and the third sub-needle 17 may display “hour” of the measurement time, and the second sub-needle 16 may display “minute”. Good.
That is, when displaying the “minute” with the third sub-needle 17, measurement is possible up to 60 minutes, and when the time becomes 60 minutes or more, the first sub-needle 15 and the third sub-needle 17 indicate “hour”. ”Is displayed, the elapsed time can be displayed in an easy-to-understand manner, and the user can accurately grasp the elapsed time to improve convenience.

  Furthermore, in the said embodiment, the 1st sub needle | hook 15 and the 2nd sub needle | hook 16 of a 1st display means which are driven with a 1st motor are arrange | positioned in the 6 o'clock position of a dial plate, and the 2nd driven by a 2nd motor Although the 3rd sub needle | hook 17 of the display means has been arrange | positioned in the center position of a dial face, it is not limited to these arrangement | positioning.
