DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an analog electronic wristwatch having multifunctional display means such as a stopwatch display and an alarm display.

[0002]

2. Description of the Related Art In recent years, multifunction electronic watches having additional functions such as a stopwatch, an alarm, and a timer have been commercialized as analog electronic watches. Means for displaying such multi-functions include, in addition to the usual seconds, minutes and hour hands, a special alarm hour / minute hand or minute chronograph at an arbitrary position on the dial, for example, at 6 o'clock or 9 o'clock. Various functions are displayed, for example, a pointer means such as a needle is provided.

[0003] In addition to the normal crown, which is an external operation member, a multi-function display switching crown or switch is used to improve the operability of each function. This not only provides many functions, but also enables various variations in watch design, responding to diversifying consumer needs.

Examples of disclosure of such a multifunction electronic timepiece are disclosed in Japanese Patent Application Laid-Open Nos. 61-28683 and 61-29438.
8, JP-A-2-77678, JP-A-2-77679, and the like.

[0005] Further, as another means for displaying multi-functions, ordinary seconds, minutes and hour hands are arranged at the center on the dial,
Separately, by changing the function displayed by the function display means arranged at the 6 o'clock position, each hand displays the function. In this case, when the function display is “time”, the long hand, the short hand, and the second hand indicate the minute hand, the hour hand, and the second hand, respectively. When the function display is changed to "stopwatch" by an external operation, the long hand, the short hand and the second hand display the minute hand, the second hand and the 1/10 second hand, respectively. In this way, the hands change the meaning of the display according to the respective functions, and wristwatches which are like ordinary three-hand watches having no special function during normal carrying are also being commercialized.

[0006]

However, in the case of a conventional multifunctional electronic timepiece having no function display means, the more the mounted functions, the more complicated the operation of the crown and switch becomes, and the very complicated the electronic timepiece becomes. Not only is it difficult to use, but also a large number of external operating members such as function switching buttons, alarm ON / OFF switching buttons, and a secondary crown are required, complicating the structure and increasing costs. I was

Further, even in the case of having the function display means, the relation between the crown operation and the button operation is complicated and difficult to understand. In particular, in a timepiece in which one hand displays a large number of functions, the display of the hands is confusing. Not only that, the method of correcting each function was also difficult to understand and complicated.

Accordingly, the present invention eliminates such a complicated operation of a multi-function electronic timepiece, and an object thereof is to provide a simple and easy-to-understand multi-function timepiece with high operability. Where you do it.

[0009]

The mode correction axle 10 without the gap is provided.
Rotation positioning of 4 can be performed without rattling, but in the assembling process, when the mode correcting axle 104 is guided only by the main plate and a force is applied by the mode correcting jumper 31, the mode correcting axle 104 tilts, and it becomes very difficult to install the train wheel bridge to be installed later. I will. Therefore by providing the aforementioned gap H _2, the improvement of the assembling property is improved. However, since the positioning and clearance H ₂ is too becomes impossible, is set to be about 2/100 mm.

By rotating the winding stem 22, the winding stem is rotated with a load torque until the jump control gear 104 e of the mode correcting axle 104 passes over the apex of the jump controlling portion 31 a of the mode adjusting jumper 31. And the jump control part 31a

Reference numeral 107 denotes a mode correcting wheel. A D-shaped hole provided at the center is engaged with a mode correcting wheel engaging portion 104d of the mode correcting axle 104, and rotates integrally with the mode correcting axle 104. The mode correction wheel 107 meshes with the internal teeth of the mode display wheel 106, and the rotation of the mode correction wheel 104 is changed to the mode display wheel 1
Tell 06. Therefore, the mode display wheel 106 can be rotated around the center of the clock. According to the above-described structure, the mode display portion 106b of the mode display wheel 106 can be disposed near the outer periphery with respect to the center of the clock, and as a result, the display area for one mode on the mode display portion 106b is widened, and a large and easy-to-view mode display is achieved. It becomes possible. The mode display wheel 106 is positioned in a plane by a mode display jumper 108, and the cross-sectional direction is held with a certain clearance by a mode display wheel pressing plate 109. Since the dynamic control of the mode display vehicle 106 by the mode display jumper 108 is transmitted as a load to the mode correction axle 104 via the mode correction vehicle 107, the dynamic control of the mode display jumper 108 is controlled by the mode correction jumper 31 described above. The setting is as weak as possible for control. Mode display jumper 108

By the rotating operation of the winding stem 22, the mode correcting axle 104 rotates as described above, and the electric mode can be switched on the front side of the watch body, and at the same time, via the mode correcting wheel 107 on the back side of the watch body. The mode display wheel 106 rotates and the mode display is switched. In the present embodiment, the number of teeth of the jump control gear 104e of the mode correcting axle 104 is six, and the number of teeth of the mode correcting wheel 107 capable of performing six functional states per one round of the mode correcting axle 104 is one.
The mode display wheel 106 has two teeth and the number of teeth of the mode display wheel 106 is set to 24, and the mode display wheel 106 is set to make a half turn around one round of the mode correction axle 104. Also, the mode correction vehicle 107
In order to match the phase of the functional state of the mode display wheel 106 with that of the mode correction wheel 107, a positioning hole 107a is provided in the mode correction wheel 107 and a 106a is formed in the mode display wheel 106 by printing. This enables a mode display that matches the electrical mode setting state.

Reference numerals 109 and 110 denote a mode display wheel holding plate and an hour wheel holding plate, respectively, which are holding members for vehicles related to the auxiliary hand display and vehicles related to the mode display. The mode display wheel holding plate 109 is the same as the dial plate 72 and has a window hole 1 for mode display.

However, according to the mode display structure of the present invention, the display section is located at any position within the range in which the mode display section of the mode display wheel 106 rotates. Because it can be set, the degree of freedom in design increases. Also, the mode display wheel holding plate 1
Reference numeral 09 has a step 109b substantially near the bottom of the inner teeth of the mode display wheel 106 so as not to rub the mode printing surface of the mode display wheel 106. The mode display wheel holding plate 109 may have a structure in which the teeth of the mode display wheel 106 are held with a certain gap in cross section, and a step is formed on the outer peripheral portion to protect the printing surface. Further, the hour wheel holding plate 110 positions the cross section of the hour wheel 10 disposed at the center of the timepiece. The upper portion of the hour wheel 10 of the hour wheel holder 110 has bending portions 110a and 110b, and is located between the mode indicating wheel holder 110 and the mode indicator wheel holding plate 109. This prevents lifting of the hour wheel 10 via the dial 72 and the mode display wheel pressing plate 109 when the hour hand 12 is pulled out of the hour wheel 10 and engages with the leading end of the hour wheel 10.

FIG. 26 is an external view of a completed multifunctional electronic timepiece of this embodiment. 60 is an exterior case, 72 is a dial. Crown 61, 2 o'clock, linked to the winding stem at 3 o'clock,
Buttons 45a and 46a are arranged at the 4 o'clock position. In the center of the clock body, the hour hand 12, minute hand 11, center hand 20
And displays the hour, minute, stopwatch second, or day, respectively. The sub-hand placed at the same distance from the center of the watch body is a 1/10 second chronograph hand 64 at 12 o'clock and a dual time 24-hour hand 66 at 3 o'clock,
The 24-hour hand 65 is at the 9 o'clock position. A mode display window 72a for displaying functions at 6 o'clock is on the dial,
The function display is displayed below the mode display wheel 106. In the present embodiment, the following six mode displays are provided, and the function corresponding to each mode display is performed. 6
The two mode displays are “TIME”,

When only the switch 51 of f is turned on, the mode becomes the 0 position set mode. When the crown 61 is in the first position (when D48 is on), when the A switch 45 is turned on, the 1/10 second chronograph hand 64 moves clockwise in steps of one step (hereinafter referred to as forward rotation direction). The hand is moved, and the center hand 20 is also moved in conjunction with the movement. When the B switch 46 is input, the 1/10 second chronograph hand 64 moves in a counterclockwise direction (hereinafter referred to as a reverse direction), and in conjunction with this, the center hand 20 also moves. A or B switch 4
By continuing to press the buttons 5 and 46, the hand can be fast-forwarded and the 0 position can be set quickly. At this time, the reference clock for hand movement Cdrv uses 128 Hz in the normal rotation direction and 51.2 Hz in the reverse rotation direction. Similarly, crown 61 is 2
When it is at the stage (when C47 is ON), pressing the A or B button 45a, 46a causes the hour hand 12, minute hand 1
The reference position of the 1 and 2 o'clock hands 65 can be set. Number of hand movement steps, hand movement direction, hand movement reference clock Cdrv
Is the same as when the center hand 20 and the 1/10 second chronograph hand 64 are set. In all other modes, the reference clock for hand movement is 128 Hz in the forward rotation direction and 51.2 Hz in the reverse rotation direction. In any mode, based on the position set in the 0 position set mode, the current position of each hand is always stored in a hand position counter formed in a part of the data memory 204.

FIGS. 27 and 28 show flowcharts of the normal time mode indicated by the indication "Time". The normal time mode is set when none of the mode switching switches are turned on. When the multi-function electronic timepiece of the present invention is used, it is expected that the time used in the normal time mode is the longest. Therefore, in this mode, since all the mode switching switches are turned off, the average current consumption is reduced. It can be expected to reduce the battery life and extend the life of the battery used. FIG. 27, FIG.
As shown in (1), when an interrupt of 1 Hz is input, 1 is added to a 15-second counter formed in a part of the data memory 204, and if the value of the 15-second counter is 15, the mode hand movement control circuit 219 Step motor A

Set the number of hands 1 to 6.

The correction of the current time is performed with the crown 61 in the second stage. Assuming that the crown 61 is the second stage, the hour and minute hands 12 and 11 are moved in the forward direction to the position of the minute.
Each time the button 45a (A switch 45) is pressed, the hour / minute hand 1
Hands 2 and 11 are moved in the forward direction in units of one minute. Button 4
Each time the 6a (B switch 46) is pressed, the hour and minute hands 12, 11 are moved in the reverse direction in units of one minute. By continuing to press the button 45a or 46a, the hand is moved at a rapid traverse, and correction in a short time is possible.

The date is corrected with the crown 61 in the first position. By pressing the button 45a while the crown 61 is in the first position, the center hand 20 is moved in the forward direction every day. Each time the button 46a is pressed, the center hand 20 is moved in the reverse direction every day. Similarly to the correction of the current time, it is possible to correct the fast forward by holding down the button 45a or 46a. When the current time reaches 24:00, the center hand 20 indicating this date instantaneously rotates the 1/10 second chronograph hand simultaneously to advance the date by one day. Therefore, unlike the conventional analog clock, the center hand 20 clearly indicates even at around 24:00 at midnight. And you can check the date.

FIGS. 29 and 30 show flowcharts of the stopwatch function. Note that “CG” used in FIGS. 29 and 30 means a stopwatch. Also,
“CG start” indicates that the stopwatch measurement is being performed and the split display is released. RA13 by crown rotation
When the switch 49e of 0e is on and the crown is at the 0th stage (the C and D switches are off), a stopwatch display and measurement operation can be performed. Each time the button 45a (A switch 45) is input, the start and stop of the stopwatch measurement are repeated. When the stopwatch measurement is started, the CG 1/10 second counter formed in a part of the data memory 204 by the CG interrupt is incremented by +
When the 1/10 second chronograph hand 64 is moved every 3 steps in 1/10 second increments and the 1/10 second counter counts 15 seconds, the data memory 20
The CG 15 second counter formed in a part of the counter 4 is incremented by one, and the minute hand 11 is moved every 15 seconds. When the button 46a (B switch 46) is input at the time of "CG start", a split display state is set, and when the button 46a (B switch 46) is input in the split display state, "CG start" is set, and 1/10 seconds The chronograph hand 64, the center hand 20 indicating the second of the measurement time interlocked therewith, the hour hand 12 and the minute hand 11 are fast-forwarded until the measurement time is displayed. Button 4 when the stopwatch is stopped
When 6a (B switch 46) is input, the stopwatch measurement is reset and each hand other than the dual time 24 stitches 66 is fast-forwarded until the 0 position is displayed. If there is no crown or button operation for 10 minutes in the stopwatch measurement state, the 1/10 second chronograph hand performs a sector-shaped hand movement centering on the 0 position as shown in FIG. Normally, 39 motor pulses are generated per second during stopwatch measurement. However, when the hand moves as shown in FIG. 31, only three motor pulses are generated per second, so the battery life can be extended. You can see at a glance that the stopwatch is being measured. FIG.
2, FIG. 33 and FIG. 34 show flowcharts of the timer function. The timer setting time is indicated by the minute hand 11. When the switches 49 and 51 of the RA 130e and the RB 130f are turned on by turning the crown, the timer mode is set. If the crown is turned to the second stage (the C switch 47 is turned on), the set time can be changed. Each time the button 46a (A switch 46) is input, the set time can be increased by one minute (4 steps). Each time the button 46a (B switch 46) is input, the set time can be reduced by one minute. By pressing and holding either button, fast forward can be set. Settings up to a maximum of 60 minutes are possible. When the crown 61 is set to the 0th stage, the operation of timer measurement becomes possible. Immediately after switching from the other mode to the timer mode, the timer set time is preset by inputting the button 46a (B switch 46), and the minute hand 11 is fast-forwarded to the set time. The start / stop of the timer is performed by a button 45a (A switch 45). When the timer operation starts, the center hand 64 moves counterclockwise by 30 steps every second and the minute hand 11 moves counterclockwise for 15 seconds, and the remaining time of the timer is displayed. However, when the remaining timer time is 5 minutes or more, the 1/10 second chronograph hand 64 performs the same sectoral movement as in the case where the stopwatch measurement is 10 minutes or more, and only the minute hand 11 displays the remaining time. The beeper sounds three seconds before the remaining time, and when the time reaches 0 seconds, a time-up sound sounds and the timer operation ends. FIG. 35 shows a flowchart of the alarm set function. Switches 50, 51 of RA 230g and RB 130f by crown rotation
Is set to the alarm set mode, the hour hand 12,
Minute hand 11, 24-hour hand 65, Dual time 24-hour hand 66

When the switch 45) is input, the minute hand 11 is moved by one minute in the forward direction and by one minute in the reverse direction each time the button 46a (B switch 46) is input, so that the alarm set time can be corrected. Button 45 as in other correction modes
By holding down the button a or the button 46a, the minute hand is rotated forward or backward at a rapid traverse, so that correction can be made in a short time. When the crown is set to the second stage, the hour hand 12, minute hand 11, 24-hour hand 65, dual time 2
When the 4 o'clock hand 66 is running to the alarm set time, the button 4
By pressing 5a or 46a, self-propelling is stopped, and the stopped position can be set as the alarm set time.

When only the switch 50 of the RA 230g is turned on by turning the crown, the hour hand 12, the minute hand 11 and the 24-hour hand 65 enter a mode indicating a normal time. In this state, the alarm set time set in the alarm set mode and the current time are set. If a match is found, the alarm sounds.

FIG. 36 shows a flowchart of a method for determining the fast-moving hand movement direction of each hand when the crown is rotated and the mode is switched. When switching from one mode to another mode, the self-propelled hand moves to the display indication position of the current mode by rapid traverse because the display contents of each mode are different, but the self-propelled time is the most I keep it short. This is the same not only when the mode is switched, but also when each hand runs in the stopwatch mode or the timer mode.

FIGS. 37 and 38 show flowcharts of a method of moving the hands of each motor. FIG. 37 shows a method of moving the motor when the number of hand movements is 14 or less. FIGS. 38 (a) and 38 (b)
Is a fast-forward hand movement method of 15 or more rounds. The "motor pulse register" in the figure is the register 2261 in FIG.
That is.

Also, the demo hands of one reverse rotation and one forward rotation are performed for each motor immediately after the system reset at the second stage of the crown, so that the rotor magnets of the step motors A3 and B13 are magnetized. Direction can be uniquely determined. That is, the rotor can be adjusted to a position that always matches the hand movement pulse signal after the system reset. Also, at this position
By attaching the / 10 second chronograph hand and the center second hand to the 0 position, even if the system is reset after the 0 position adjustment, the hands can be operated normally without shifting the 0 position.

The multifunction electronic timepiece of the present invention has a time alarm function, a 12-hour alarm function, and the like in addition to the above functions. And whether the D1, D2, and D3 terminals are connected to V _DD . For this reason, it is possible to configure a clock having several types of specifications with one IC.

In contrast, by defining the functions at the first and second stages of the winding volume and enabling correction of the date, time, alarm time, etc., it is very easy to understand and use, despite being a multifunctional electronic timepiece. Operation specifications are realized. Furthermore, in the current time display function state, the date and time can be corrected in the first row of the Makima and the time can be corrected in the second row of the Makima. Therefore, the date and time can be corrected in the same way as a general wristwatch. , Improving usability. In addition, since the correction of the 24-hour hand is mechanically performed by rotating the winding stem at the first stage of the winding stem, the electrical correction of the other hour and minute hands and the date can be made independent. The operability has been further improved.
