Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a means for setting calendar information required for uncorrected end of month as well as uncorrected end of month of a pointer type electronic timepiece dated by a date indicator.

[0002]

It is no exaggeration to say that, nowadays, a large number of pointer type yearly timepieces have been commercialized, and the user has no opportunity to adjust the time by pulling the crown.

[0003] A pointer-type timepiece having a date by a date indicator as calendar information has been commercialized not only as an electronic timepiece but also as a mechanical timepiece. The conventional pointer-type timepiece with the date applied by the date indicator is a mechanism for decelerating the rotation of the hour wheel with the hour hand by half and rotating the date indicator once a day to update the date. Since the date display is always displayed up to 31st in this mechanism, the user corrects the date indicator on the 1st day of the next month in the small month up to 30th of one month on the calendar.

However, many end-of-month uncorrected mechanisms have been proposed since the days of mechanical timepieces in order to eliminate the above-mentioned corrections to the user.
Being developed. Most of them have a mechanism such as a month hand for displaying the month and a month wheel on the dial plate, and control the date display by obtaining information from the month display mechanism, which enables correction at the end of the month.
There is also a mechanism for displaying the year, such as a year hand and year wheel, which also controls the date display means that comes from the leap year on the calendar.

Even in the electronic timepiece, the microcomputer and the multi-motor mechanism are used to enable correction at the end of the month. For example, by driving a date indicator that displays the date with a dedicated motor, you can set the year or month using the hour and minute hands only when setting the first calendar, or when the watch is shipped from the factory or when the battery is replaced. By writing the information in the microcomputer, the calendar correction by the user is omitted.

[0006]

However, it is limited to the dial of a watch that a conventional month hand or year hand is applied or that a microcomputer is used to display a large amount of information (for example, year or month). There is a drawback that the time information is read and hated by the calendar information of the year and month, which is messed up in the space provided and is not used often.

In the method of writing the calendar information in the microcomputer in the timepiece described in the prior art, the display of the timepiece itself and the dial on the dial is the same as a normal timepiece for the user. The clock is easy to see because it is controlled, and the date does not need to be corrected. However, there is no dedicated device in the usual watch shop to input new calendar information when the calendar information in the microcomputer is over or the battery in the watch has run out, so at the watch factory or a predetermined watch repair shop. It needs to be modified inside the microcomputer, and it is not suitable for the present where the watch battery can be replaced anytime and anywhere.
In addition, sales of watches cannot be sold in large quantities when considering repairs of watches.

The object of the present invention is to eliminate the above-mentioned drawbacks and to set calendar information in a timepiece by a simple method and to display the date display based on the set calendar information without modification at the end of the month. It is to provide a pointer-type clock with a date display.

[0009]

In order to solve the above-mentioned problems, according to the present invention, an hour and minute hand, a date indicator as a calendar display, a dial having a window for displaying the date indicator, and every 24 hours. A 24-hour detection means for outputting a date change signal to
Calendar counter means for updating calendar information based on a date change signal from the 24-hour detecting means;
A date indicator control means for generating a control signal for controlling the drive amount of the date indicator based on the date change signal from the four-hour detection means and the contents of the calendar counter means, and a date indicator drive based on the control signal. In a calendar mechanism of a timepiece including a timepiece module having a date indicator driving means, the timepiece module has a calendar setting means for setting desired date information in the calendar counter means on the back side thereof. To do. Further, the clock module detects the date displayed by the date indicator, and date adjusting means for matching the display date of the date indicator with the contents of the calendar counter means based on the date information from the date detecting means. And having. The date detecting means is a sensor means for detecting a specific position of the date indicator and outputting a detection signal, and the date adjusting means is a detection signal from the sensor means and desired date information set in the calendar counter means. Based on the above, the day difference calculating means for calculating the day difference from the specific position to the desired date position and outputting the day difference signal, and the day wheel based on the day difference signal to the desired position from the specific position. It is characterized by comprising a date indicator control means for driving to the date position. Further, the calendar setting means has a digital display section for displaying the contents of the calendar counter means, and a switch for setting the date on the digital display section. Further, the calendar setting means is provided corresponding to each month and day, and comprises a rotary switch for outputting month and day information, and means for initially setting the month and day information in the calendar counter means. Further, the calendar setting means is housed in the watch case, and is exposed only when the case back constituting the watch case is opened.
Further, the calendar counter means has a month-end uncorrected function. Further, the digital display unit is characterized in that the battery unit constituting the timepiece module is arranged so as to be shifted in a plane.

Forward rotation time correction signal P62a, reverse rotation time correction signal P62b
Then, based on the date change signal P60 from the 24-hour switch 60, the normal correction signal Pa and the reverse correction signal Pb are output to the calendar counter means 53b and the date indicator control means 53c. Reference numeral 53f is a gate means composed of AND gate means G and H, which is used to open / close the signal P10 from the back cover open / close switch 10.
Is output, the forward correction signal Pa and the reverse correction signal P are output.
It is controlled so that b is not input to the calendar counter means 53b.

Next, the correction operation of the timepiece of this embodiment will be described. First, normal time adjustment
With the rotation correction by the crown 6, the hands can be corrected by a mechanical time adjustment mechanism (not shown) as in the case of a normal timepiece type timepiece. Further, in the present embodiment, the switch signal control means 53e of the microcomputer 53 uses the forward correction time signal P62a coming from the leftward rotation direction of the crown 6 and the date change signal P60 coming from the 24-hour switch 60 to cause the correct correction signal Pa to pass.
Is output and the calendar counter means 53b is corrected (that is, the date is advanced). The date indicator control means 53c controls the date indicator drive control signal P in the forward rotation direction based on the correct correction signal Pa.
54 is output, and the date indicator 56 is corrected by normal rotation for one day.

On the contrary, the switch signal control means 53e of the microcomputer 53 outputs the reverse correction signal Pb by the reverse rotation time correction signal P62b coming from the clockwise direction of the crown 6 and the date change signal P60 coming from the 24-hour switch 60, and the calendar counter. Reverse the means 53b (ie delay the date). The date indicator control means 53c outputs the date indicator drive control signal P54 in the reverse rotation direction based on the reverse adjustment signal Pb, and corrects the date indicator 56 by reverse rotation for one day.

The calendar is corrected at a watch production factory or a watch shop after inserting a new battery 8 at the time of opening the back cover for repair, battery replacement, or the like. That is, as shown in FIG. 1, when the back cover is removed, the contents of the calendar counter means 53b are displayed on the liquid crystal display unit 9 via the display control means 53d by the signal from the back cover opening / closing switch 10. As shown in FIG. 8, in this state, the calendar setting switch 52 is operated like a normal digital clock.
Input the first two-digit month and middle two-digit date to the calendar counter means 53b. Next, pull the crown in two steps 6
Correcting the pointer with 2 and passing 12 o'clock in the middle of the night, 24
The time switch 60 generates the date change signal P60, and the AND gate means C or D, OR of the switch control means 53e.
After passing through the gate means A or B, F of the date indicator control means 53c
The date and time is input to the terminal or the R terminal to rotate the date dial 56. Therefore, it is determined whether the date dial 56 is rotated or not, and am / pm is determined to correct the time.

Next, in the state where the crown is pulled to the first stage 61, the date dial 56
While looking at the liquid crystal display 9, set the date to the set date.
When the back cover is opened, that is, when the back cover opening / closing switch 11 is operating, as described above, the AND gate means G and H of the gate means 53f cause the opening / closing signal P10 from the back cover opening / closing switch 10.
Since the normal correction signal Pa and the reverse correction signal Pb are controlled so as not to be input to the calendar counter means 53b, there is no influence on the calendar information set in the calendar counter means 53b. After setting the time and date, the crown 6 is returned to the normal use state, the back cover is closed, and the correction work is completed.

In normal use, the forward rotation time correction signal P62
Since neither a nor the reverse rotation time correction signal P62b is output, the output of the NOR gate means F becomes H level, and the date change signal P60 from the 24-hour switch 60 generated every 24 hours is received by the AND gate means E and OR gate. Pass through means A. Then, the switch control means 53e outputs the correct correction signal Pa, and the gate means 53f performs an AND operation.
The calendar information is updated by being input to the U terminal of the calendar counter means 53b through the gate means G, and the correct correction signal Pa is input to the F terminal of the date indicator control means 53c to rotate the date indicator 56 in the forward direction. Rotate.

With the above operation, the microcomputer outputs the date and time set when the back cover is opened and the date indicator drive signal P54 for advancing the date indicator 56 according to the calendar information in the microcomputer 53, and the date and time set when the back cover is opened. Proceed. Thus, as long as the month and day set when the back cover is opened and the date 5 displayed by the date indicator 56 are the same, the user does not need to correct the calendar. In particular, in this embodiment, the calendar counter means 53b has an automatic calendar function, and there is no need to correct the date indicator at the end of the month. It is possible to provide a clock that does not bother.

Next, a second embodiment of the present invention will be described.
FIG. 5 is a system block diagram of the timepiece showing the second embodiment, and is a system block diagram in which a sensor 115 is added to detect the display position of the date indicator 56 in FIG. Figure 6
Is a sectional view showing the date wheel train 55 provided with the sensor 115, and FIG. 9 is a block diagram showing a processing function of the microcomputer 53.

In FIG. 6, the main plate 106 and the train wheel bridge 108.
The rotor 113 for driving the date dial 56 during
By arranging the wheel train of the date driving wheel 109, the A intermediate wheel 110, the B intermediate wheel 111, and the C intermediate wheel 112 that are transmitted up to the date wheel 56
Drive. The dial 1 has a window 1a for displaying the date 5. The date dial 56 has a protrusion 56a at one place,
Corresponding to the reference position of. Reference numeral 115 denotes a sensor that emits light and detects the amount of reflection, and is provided in the circuit 114. The light of the sensor 115 is reflected by the date dial 56 through the hole 106a of the main plate 106. At this time, when the light of the sensor 115 is reflected by one projection 56a on the date dial 56, the amount of reflection is different when the light is outside the projection 56a. Therefore, since the reflection amount is different only in one place, the sensor 115 can detect the reference position of the date indicator 56.

Next, the processing function of the microcomputer 53 will be described with reference to FIG. The same blocks as those in FIG. 8 are assigned the same numbers and their explanations are omitted. In the figure, 53g is a switch control means, which is different from FIG. 8 only in that there is no OR gate means B and that the signal when the crown 6 is pulled to one stage is not input. Reference numeral 53h is a day difference calculating means, which inputs the calendar information signal Pc from the calendar counter means 53b, and based on the detection signal P115 from the sensor 115, the date of the set calendar information and the date wheel currently displayed. The difference with 56 dates (1 day which is a specific day) is calculated and the day difference signal Pd is output.
Reference numeral 53i is a date indicator control means, which has the same basic function as that of the date indicator control means in FIG. 8, except that the initialization signal P61 output when the crown 6 is in the one-pull state 61 is input. A continuous drive control signal P54a for continuously driving the date dial 56 is generated, and an initial setting control signal P54b for driving the date dial 56 to the date position of the set calendar information is generated based on the day difference signal Pd. 53j
Is an OR gate means, which is a positive correction signal Pa and a daily difference signal P.
d is output to the F terminal of the date indicator control means 53i.

Next, a description will be given of the calendar correction according to the second embodiment of the present invention. The time adjustment is the same as that in the above-mentioned embodiment and will be omitted here.

The calendar correction according to the second embodiment is similar to that of the above-described embodiment, that a new battery 8 is inserted at the time of opening the back cover for repair, battery replacement, etc. at a timepiece manufacturing factory or a watch shop, and then, like a normal digital timepiece. 2 by the calendar setting switch 52
Enter the month of the digit and the date of the middle two digits. Also, the time is adjusted in the same manner while watching the 56-day rotation of the date indicator in the morning and afternoon in the state where the crown is pulled by two steps.

Next, how to set the date on the liquid crystal display portion 9 of the date indicator 56 in the state of the crown first pulling 61, which is a feature of the second embodiment, will be described. When the date and time of the liquid crystal display section 9 is input in the aforesaid two-step pulling 62 state and the state is set to the one-step pulling 61-degree pull, the initialization signal P61 is output from the pull-out position detecting mechanism of the crown, not shown. It is input to the vehicle control means 53i. The date indicator control means 53i generates a continuous drive control signal P54a based on the initialization signal P61, and the date indicator drive unit 54 and date wheel train 55.
The date wheel 56 is continuously driven via the. And the sensor 115
Outputs a detection signal P115 when it detects a specific position of the rotating date wheel 56, that is, one day in this embodiment.

Next, the day difference calculating means 53h calculates the difference between the date of the calendar information set in the calendar counter means 53b and the date of the date wheel 56 currently displayed (one day which is a specific day). And outputs the daily difference signal Pd. The date difference signal Pd is input to the F terminal of the date indicator control means 53i via the OR gate means 53j, and the date indicator control means 53i generates the initial setting control signal P54b based on the date difference signal Pd to drive the date indicator 56. Drive to the desired date display position and stop. After that, the crown 6 is returned to the normal use state and the case back is tightened.

According to the above processing function, the date wheel can be automatically set by a simple crown operation after storing the calendar information in the calendar counter means 53b, so that a more convenient clock can be constructed. Is.

Further, although the calendar setting switch 52 of the liquid crystal display 9 is used as the date setting of the calendar of the embodiment of the present invention described above, the date setting of the calendar when the other back cover is opened. As a method, FIG. 7 shows a third embodiment of the present invention.

In FIG. 7, 14 is a leap year (Leap Y).
EAR) and a rotary switch for setting the year indicating the leap year, 15 is a rotary switch for setting the month indicating the month, 16 is a rotary switch for setting the day indicating the tens digit of the day, and 17 is the day. This is a rotary switch for setting the day on which the ones digit is displayed, and there is an arrow mark 18 representing the setting position of each rotary switch.
The date on the calendar in FIG. 7 indicates the 24th day of December, which is three years after the leap year. In other words, in this embodiment, the date can be set on the calendar by rotating the rotary switch instead of the liquid crystal display unit 9 and the calendar setting switch 52 as in the calendar set described above.

In the third embodiment of the present invention, the operation is performed as in the first or second embodiment except for the above-mentioned calendar date setting.

If the hand-held timepiece described in each of the embodiments described here is an annual-difference timepiece, the user has almost no chance to correct it with the crown 6 after inserting the battery 8.

Even if the user goes abroad to adjust the time difference, unless the back cover opening / closing switch 11 works, the date is corrected by the crown 1-step pull 61, the time is corrected by the crown 2-step pull 62, and the date change signal P60 is sent. If it occurs, the forward rotation time correction signal P62a and the reverse rotation time correction signal P62b
From this, it is possible to determine whether the time difference is corrected in the forward or reverse direction, and the watch itself corrects the date dial 56 without modification at the end of the month according to the calendar information in the microcomputer 53 in conjunction with the user's correcting action.

As can be seen from FIG. 2, the timepiece of the present invention is no different from the ordinary pointer type timepiece on both the front and back sides, and is a smart timepiece for the user.

Although the optical sensor and the day difference calculating means are shown as the matching means of the date indicator and the calendar counter means in the above embodiment, the present invention is not limited to this. It is also possible to use a method in which the display date is added to detect the display date and match it with the calendar counter means, or a method in which the mechanical switch detects the rotational position of the date indicator and matches it with the calendar counter means.

[0038]

According to the present invention, not only is it the same as a conventional pointer-type timepiece having a function of displaying the date, but the previous date can be uncorrected at the end of the month, and the date to be displayed does not end at the end of the month. There is no need to add a month or year hand, which has been done in the past to correct it, or to display a lot of information (for example, year or month) with one hand using the function of the microcomputer. There is no drawback of cluttering the limited space of boards with various scales of calendar information and reading the time information.

Further, the calendar set can be easily corrected by the battery replacement technique of each conventional watch repair shop, and a microcomputer or a dedicated device or tool for the present invention is not required. In addition, there is no need to worry about acceptance by not only the user but also a watch repair shop in selling watches without requiring special technology. However, anyone can easily modify it, and once set it can provide a watch that will not be modified until the next battery replacement.

Further, by horizontally shifting the battery and the liquid crystal display unit as shown in FIG. 1 of this embodiment, the liquid crystal display unit can be replaced like a normal battery replacement without disturbing the replacement of the battery.

According to the second and third aspects, since the date indicator and the calendar counter means are provided with the matching means, the date indicator can be easily set on the desired date even when the battery is replaced.

According to the fourth aspect, the setting of the calendar information is the same as that of the conventional digital timepiece setting method, so that it can be easily set.

According to the present invention, the calendar information can be set with a rotary switch.

According to the eighth aspect, since the digital display portion does not overlap the battery, a thin timepiece can be constructed.

According to the ninth aspect, the digital display is displayed only when the case back is opened, and is turned off during normal use, so that power consumption can be reduced.
