〔Example〕

FIG. 1 shows a top view of the cased electronic timepiece according to the present invention. Packing 7 on the case outer body 67
A windshield 29 is fixed via 1. On the inner surface of the windshield 29 are letters 29a and parting 2.
9b is printed to balance the design and cover the outer periphery of the parting board 10. Parting board 1
0 has three openings 10a, 10b, and 10c, the upper frame 10a and the lower right frame 10b serve as digital display windows, and the lower left frame 10c serves as an analog display window. The parting board 10 has the operation function of the push button 9, the display function of the digital display section,
Other printing is included. In other words, the parting plate 10 serves as a common parting member for the digital display part, which is an electro-optical display part, and the analog display part.

At the bottom of the upper frame 10a of the display, there are four 7-segment numbers, as well as “TIME”, “CALENDER”,
“STOP.W”, “LAP”, “:”, “−”, “▽” “▽
It has a display section displaying marks such as "▽", and a display section displaying a mark "1/100" as well as a two-digit display section consisting of 8 and 9 segments is located at the bottom of the lower right frame 10b. The digital display section is configured to be visible through the frames 10a and 10b.The analog display section is visible through the lower left frame 10c, and the time is indicated by the dial 17 and two hands, the hour hand 28b and the minute hand 28a. Perform analog display.

Hour hand operation and correction are done using 4 push buttons 9
A, 9B, 9C, 9D and Reuse 19 are used. In principle, operations and corrections on the digital display section and analog display section are independent, and operations and corrections on the digital display section are performed using 4 pushbuttons 9.
A, 9B, 9C, and 9D, and the analog display section is operated and corrected by the reuse 19.
The digital display section and analog display section are easy to understand and have excellent operability because they follow the conventional operating and correction methods.

The digital display section visible from the digital display frames 10a and 10b normally displays "hours and minutes" in the 4-digit segment in the upper frame 10a, and "seconds" in the 2-digit segment in the lower frame 10b. ”
mark is displayed. The "hour" is displayed in the 24-hour system (0.1...23), and the analog display frame 10c
Since the 12-hour time is displayed on the analog display inside, by using both displays, you can directly read the time in either 12-hour or 24-hour format, making it extremely convenient and easy to use. By pressing the push button 9A ( _S1 in the figure means a switch linked to the push button 9A), the normal display is switched to the calendar display, and the display section in the upper frame 10a displays "Month,
``Day'' is displayed in the display section in the lower frame 10b of ``CALENDER'' and the ``-'' mark is displayed. The "day of the week" display is similar to the display method used in conventional digital watches, which displays the first two letters of English words in two digits of 8 and 9 segments. The time is displayed in the analog display frame 10c, and the digital display frame 1
By displaying the calendar in 0a and 10b, almost all the necessary time-related information can be directly read by using both displays, which is extremely convenient and easy to use.
In particular, the calendar can also store "year" information in the corrected state, making it possible to create a complete perpetual calendar that not only distinguishes between "small months" and "large months," but also "leap years." Therefore, there is no need to bother with adjusting the date at the end of the month of the month unlike the mechanical calendars added to conventional analog display watches. Because the calendar of conventional analog display clocks uses a mechanical mechanism, small months and
Realizing a perpetual calendar that operates accurately by determining major months and leap years would require an extremely complex mechanism and a large amount of cost, and would be almost impossible to achieve in reality.

In this invention, the time display uses a familiar
By using an easy-to-read analog display and an electro-optical display mechanism for the calendar display, we have achieved a perpetual calendar with high reliability and low cost that requires only initial setting and does not require any correction until the clock has completely stopped. ing.

To correct the time, press pushbutton 9B ( _S2 in the diagram means the switch linked to pushbutton 9B) to select the correction digit, and to correct the flashing correction digit on the digital display press pushbutton 9A and switch _S1 . This is done by closing the . The correction order is "seconds" → "minutes" → "hours" →
The order is ``month'' → ``day'' → ``day'' → ``year.'' After ``month,'' a ``CALENDER'' mark is displayed, and before that, a ``TIME'' mark is displayed.
"Seconds" correction is set to "seconds return to zero", and when seconds are corrected between 00 and 29 seconds, the seconds are rounded down and displayed as "00" and are not carried to "minutes". From 30 to 59 seconds, the time is rounded up to "00" and at the same time "1" is added to the "minute". For corrections other than "seconds", "1" is added to the flashing digit by pressing the push button 9A once, and no carry is carried out to the higher digits. For the "year" display, all displays except the "CALENDER" mark are erased, and the last two digits of the Western calendar are displayed in the lower frame 10b, and a number that is divisible by 4 is determined to be a "leap year" and "February 29th" is displayed.
Display up to.

The push button 9C ( _S3 in the figure means a switch that reaches the push button 9C) turns on the lamp and returns the digital display in the corrected state to the normal display.

By pressing the push button 9D ( _S4 in the figure means a switch linked to the push button 9D), the normal display or calendar display state is switched to the stopwatch display. In the stopwatch display state, "minutes, seconds" and "STOP.W""▽,▽▽" marks are displayed in the upper frame 10a, and "1/100 seconds" and "1/100" marks are displayed in the lower frame 10b. is displayed. When the stopwatch is displayed, push button 9C starts.
This is the stop operation button, pushbutton 9
A is the lap and reset operation button. When the push button 9C is pressed to start the stopwatch, the "▽, ▽▽" marks flash to indicate that the stopwatch is in the starting state. If the push button 9C is pressed again in this state, the stopwatch will stop and the "▽, ▽▽" marks will stop flashing and continue to illuminate. Time can be accumulated by repeatedly operating the push button 9C, and the net time of the game excluding lost time, rest time, etc. can be easily measured. When the push button 9A is pressed while the stopwatch is stopped, the display becomes "□□▽□□▽▽□□" and is reset. When push button 9A is pressed while the stopwatch is in the RUN state, the lap time will be displayed and the "LAP" mark will light up. At this time, the "▽, ▽▽" marks continue to flash, indicating that the stopwatch is still in a developing state. If push button 9A is pressed again while the lap is displayed, the "LAP" mark disappears, the lap is canceled, and the stopwatch returns to displaying the elapsed time. Lap time is not only useful for measuring the elapsed time during a race, but it is also a combination of lap time and stopwatch elapsed time.
By using two, it is also possible, for example, to simultaneously time the first place record and the second place record in races that started at the same time. In this case, after pressing the push button 9C to start the stopwatch, first press the push button 9A for the first place record, then press the push button 9 for the second place record.
Press C to measure. In this state, the first record is displayed as the lap time, and when the push button 9A is pressed to cancel the wrap, the second record is displayed as the stopwatch elapsed time. In recent sports competitions, we have entered an era where people compete for speeds ranging from 1/10 second to 1/100 second, and it is almost impossible to measure this on an analog display because it includes reading errors. In the clock of this embodiment, a familiar analog display clock with easy-to-read hands is used to read the time, and a digital display clock is used to accurately measure time during sports etc. All the functions are combined into one clock, making them extremely easy to use and convenient.

As mentioned above, not only does it have both an analog display and a digital display, but the digital display is convenient because it incorporates many functions such as time, calendar, and stopwatch with lap function into one watch. However, the more functions there are, the more complex the operations become, and problems arise in terms of ease of use.
Therefore, in order to make the watch in this embodiment easier to understand, the traditional reuse 19 is used to correct the analog display, and the hands 28a and 28b are corrected by pulling it out one step and rotating it left and right. We follow the same system. This correction method is already so widely used that no explanation of how to use it is required, and it is extremely easy to understand. Also, digital display correction/
There are 4 push buttons 9A, 9B, 9 for operation.
By using C and 9D separately for each function, duplicate operations and functional operations (pressing a combination of multiple push buttons at the same time, pressing and holding for several seconds, etc.) are avoided and easy to understand. Also, by using many marks on the display panel, consideration has been given to making it possible to determine at a glance what is currently being displayed.

FIG. 2 is a block diagram showing the structure of the electronic timepiece according to this embodiment. 1 is the circuit section, which is composed of an amplifier for the oscillation circuit, a frequency dividing circuit, a timing circuit, a control circuit, a booster circuit, a decoder circuit, a liquid crystal cell drive circuit, a converter drive circuit, etc., excluding the booster capacitor chip. 1 chip of C-
Since it is housed in MOSIC, it achieves high reliability, low power consumption, and low cost. A power supply section 2 supplies power to the circuit section 1, and the battery life is extended by using a high-density energy battery such as a button-shaped small silver battery, mercury battery, or lithium battery. Reference numeral 3 denotes an oscillation section, which is composed of a small crystal resonator, a small trimmer capacitor for frequency adjustment, a capacitor for temperature compensation, and the like. 4 represents a digital display section;
Electro-optical display devices such as LEDs, liquid crystal cells, and electrochromism are used, but liquid crystal cells currently have superior properties in terms of cost, power consumption, visibility, lifespan, reliability, etc. Reference numeral 5 denotes an electro-mechanical converter such as a step motor, which receives drive pulses from the circuit section 1, generates a magnetic field in a coil, converts it into rotational motion of a rotor, etc., and transmits it to the wheel train 6.

Mechanical deceleration is performed in the wheel train 6, and an analog display section 7 with a pointer displays the time such as hours, minutes, seconds, etc. The correction section 8 is divided into a correction section 8a for the digital display section 4 and a correction section 8b for the analog display section 7. The digital correction section 8a is constituted by a push button or the like, and basically corrects the display on the digital display section 4 by sending an electrical correction signal to the control circuit of the circuit section 1. The analog correction section 8b is composed of so-called back parts such as a winding stem, a Tsuzumi wheel, a Kotetsu wheel, a Hino-ura wheel, a cannula, and a Ura pusher, with the reuse as an external operation member, and it mechanically corrects the pointer and at the same time. , a reset lever or the like is used to send an electrical correction signal to the control circuit of the circuit section 1 in order to correct the timekeeping circuit and control the converter drive circuit. That is, when the crown is pulled out and the hands are turned, a part of the clock circuit is reset and the converter drive output is turned OFF.

As described above, the digital display section 4 and the analog display section 7 each have independent correction sections 8a and 8b, and follow the correction method of conventional digital and analog clocks, making it easy to understand and easy to operate. The corrections on the analog display section 7 and the corrections on the digital display section 4 are not linked except for the "second" correction. This makes the operation easier to understand by providing an analog correction section 8b and a digital correction section 8a corresponding to the analog display section 7 and the digital display section 4, respectively, and the analog display section 7 and the digital display section 4 are completely separated. It is intended to be used as a dual-time watch that can indicate the time of day. For example, when using the digital display section 4 as a clock set to the time in your home country and the analog display section 7 used as a clock set to the local time at your travel destination, it is necessary to leave the digital display 4 as is and only adjust the analog display 8. . That is, the digital and analog time sets must be unlinked and independent.

When the digital display 4 and the analog display 7 are used as a clock that indicates the same time, it is more convenient if the digital display 4 and the analog display 7 are adjusted in conjunction with each other because they can be set only once. However, with crystal oscillation type electronic watches, the error per month is only a few seconds, and there is almost no need to make corrections in units of minutes or more during normal carrying, and it is rarely necessary to make corrections in units of minutes or more during normal carrying.
Adjusting the seconds once every few months is sufficient to maintain the accuracy of the clock. Conversely, second correction is a necessary condition in order to maintain the accuracy of the clock's indications. Therefore, in the timepiece according to this embodiment, only the seconds are corrected in conjunction with the second correction on the digital display 4, and the analog display 7 is corrected. This is especially troublesome when the second hand is attached to the analog display 7 and the analog and digital corrections are not linked. It is difficult to match the seconds exactly. Even if there is no second hand on the analog display 7 or only a minute hand, if the analog and digital are not linked, correcting the second on the digital display 4 will cause a discrepancy between the instructions on the digital display 4 and the analog display 7. This discrepancy may be small and negligible in terms of the angle of the minute hand if you only adjust the seconds for a few seconds, but in general, the error of a clock is determined by the initial adjustment, so it may lead or lag. As I tend to repeat the digital seconds correction, the deviation of the pointer on the analog display 7 accumulates and becomes an amount that cannot be ignored. In this case, as in the case with a second hand, the analog display 7 can be corrected at the same time as the digital display 4 seconds, but it is troublesome to adjust the hands for several seconds on a watch with a two-hand display. It is. Even when using the digital display 4 and the analog display 7 as a dual time watch that shows completely different times, there is almost no need to use them differently in seconds, and the analog display 7 can be adjusted in conjunction with the second correction on the digital display 4. There is no inconvenience.

The concept of linking the "seconds" correction on the analog display 7 and digital display 4, but not interlocking the corrections for "minutes" and above, is due to the error in the oscillation frequency of the crystal oscillator and the "set" function of the correction function, such as time difference correction. It is divided into a function to "correct" the instruction error caused by etc.
It can be said that analog and digital are not interlocked in the function of ``setting,'' and that analog and digital are interlocked in the function of ``correction.''

FIG. 3 shows a block diagram for explaining the above-mentioned analog/digital interlocking and non-interlocking. The contents of the circuit section 1 in FIG. 2 are subdivided, and the digital correction section 8a is composed of switches S ₁ , S ₂ and S ₃ . The shift register 1aa selects a digital correction digit according to the number of operations of the switch _S1 , and AND circuits 1ab, 1ac...
The signal from the switch _S2 is sent to the clock circuit 1d.
The first operation signal of the switch _S1 selects the second correction state of the shift register 1aa. When the switch _S2 is closed at this time, the AND circuit 1ab sends a signal to the reset terminal R of the second counter 1da of the timekeeping circuit 1d to reset the second counter 1da, and at the same time this signal is sent to the analog correction control circuit 1b for conversion. Controls the analog output signal sent to machine 5. In the analog correction control circuit 1b, if a reset signal is sent when the second counter 1da is between 0 and 29 seconds, it is determined that "the clock is advancing" and the analog output is cut by the counted amount. Further, when the second counter 1da is between 30 and 59 seconds, it is determined that the clock is late, and the analog output signal corresponding to the amount short of 60 seconds is fast-forwarded to the converter 5. For example, in a watch whose analog display section 7 moves in 1-second steps,
If the second zero returns when the digital display section 4 indicates 15 seconds, the digital display section 4 changes to display 00 seconds and the analog output stops outputting for 15 seconds (if the second hand is attached, the second hand stops). ). similarly
If the seconds return to zero at 40 seconds, the digital display section 4
becomes 00 seconds, 1 minute is added to the minute digit, and 20 fast-forward signals of about 8 to 32 Hz are sent as analog outputs. If the analog display 7 and the digital display 4 match at the initial setting, no matter how many times the seconds are corrected, there will be no discrepancy between the two displays.
Although the explanation has been made using a 1-second step movement with a second hand, the same applies even if the display means and the interval of hand movement are changed.

With the second operation signal of switch _S1 , shift register 1aa is selected to the minute correction state, and at this time the switch
When S ₂ is operated, the number of times the switch S ₂ is operated is
A signal is sent to the minute counter 1dc via the AND circuit 1ac and the OR circuit 1db, and the minute on the digital display section 4 changes. At this time, there is no influence on the analog correction control circuit 1b, and the analog and digital are in a non-interlocked state. The analog display section 7 is not affected by the digital correction in the same manner as the time correction and the like.

Next, a method for initializing the analog display section 7 and the digital display section 4 will be described.

In the watch of this embodiment, the digital display section 4 and the analog display section 7 are not interlocked except for the second adjustment, as described above, and the adjustment sections 8a and 8b are independent from each other.
Therefore, initial settings other than seconds can be easily performed. Initial setting of seconds is started by setting the analog display 7 in accordance with the digital display 4. That is, as will be described later, the analog correction section 8b is operated by the reuse operation in the same way as in general analog display type electronic watches, but when the reuse 19 is pulled out one step, the analog correction control circuit 1b is operated.
Send a control signal to stop the analog output signal. By rotating the reuse in this state, the wheel train 6 is turned and the analog display section 7, that is, the pointer 28
a and 28b can be adjusted to desired positions.
Since the second hand is stopped when the second hand is pulled out to the first position of the reuse 19, when the seconds display on the digital display section 4 and the second hand match, push the reuse 19 and start the analog display section 7, so that the analog display section 7 and the digital display The initial set of section 4 is completed. If there is no second hand, it is sufficient to carefully align the minute hand position of the analog display section 7 with the digital display section 4.

Furthermore, by pressing switches _S2 and _S3 at the same time, the digital display section 4 is displayed without interlocking with the analog display section 7.
You can also adjust the seconds. This is done by setting the analog display section 7 first, and then setting the digital display section 4 accordingly.
The purpose of this is to make initial setting easier and to make logic tests of the circuit 1 easier. In FIG. 3, when switches _S2 and _S3 are closed at the same time, a signal is sent to the reset terminal R of the second counter 1da by the AND circuit 1g to reset the seconds to zero. If you limit the purpose of this signal to the logic test of circuit 1, then AND circuit 1g
It is also possible to perform an all reset by sending the output signal not only to the second counter 1da but also to the reset terminals of the minute counter 1dc and the hour counter 1de. In any case, since the purpose is to "set" and not to "correct", the analog display 7 is not linked to the corrective operation on the digital display 4.

As mentioned above, when performing a correction equivalent to "correction" such as setting the digital display section 4 to zero seconds, the analog display section 7 is linked, and "setting" such as time difference correction or initial setting of the digital display section 4 is performed. '', the analog display section 7 should not be interlocked, and conversely, the analog display section 7 should not be interlocked with the digital display section 4, regardless of whether it is a "correction" or "set". As a result, the initial setting and interlocking mechanism of the analog display section 7 and the digital display section 4 can be realized with an extremely simple mechanism and an easy-to-understand operation method, which has a great practical effect.

Further, by adding not only a seconds return operation linked to the analog display 7 but also a seconds return operation not linked to the analog display 7, initial setting of the digital display section 4 and the analog display section 7 can be made extremely easy.

In FIG. 3, 1c is a frequency dividing circuit, 1e is a decoder, and 1f is a driver.

Next, the planar structure of an electronic timepiece that is an embodiment of the present invention will be explained based on FIG.

In the figure, reference numeral 11 denotes a liquid crystal cell which is an electro-optical display section, and is constructed in a substantially rectangular shape with long sides and short sides. It is approximately L-shaped. The liquid crystal cell 11 has cell fixing screws 14A, 1
Cell presser 13A fixed by 4B and 14C,
13B, the long side of the side without the notch and the part of the long side of the side with the notch that are not the notch are held respectively, and the IC chip 35 mounted on the circuit board 34 is connected to the circuit. a connector 12A that is an electrically conductive member between the substrate 34 and the liquid crystal cell 11;
12B, and according to various signals from the IC chip 35, various displays as described above are performed. A small iron train 2 is attached to the cut-off corner 11a of the liquid crystal cell 11, with the main plate 32 as a base.
4. The digital display is arranged so that approximately half of the planar area of the analog display section consisting of the day wheel 25, cylinder pinion 26, hour wheel 27, minute hand 28a, hour hand 28b, dial 17, etc. is accommodated. and analog display create a unique design that gives a sense of unity.

The dial 17 is placed at the bottom left with the 12 o'clock direction up (in Figure 4, it is written with the 3 o'clock direction up, so it appears at the bottom right). When the digits indicate "hour" and the right two digits indicate "minutes," the lower frame 10b indicates "seconds," and the upper frame 10a indicates "month" and "day" when lower frame 1.
0b indicates "day of the week", and when upper frame 10a displays "minutes" and "seconds", lower frame 10b indicates "1/1".
00 seconds” represents the flow of time, relevance,
For ease of understanding, the liquid crystal cell 11 in the lower frame 10b
The part is always displayed on the liquid crystal cell 11 in the upper frame 10a.
It is most desirable to place it at the bottom of the two digits to the right of the section.

Therefore, the analog display frame 10c occupies the lower left corner of the module (8 o'clock position). As seen in FIG. 4, an analog movement is disposed on the lower surface of the dial 17, and a reuse 19, which is an external operating member serving as an analog correction section, is provided at the 8 o'clock direction of the watch. The reuse 19 is generally placed at the 3 o'clock direction for ease of operation, but the dial 17
It is easier to understand if the crown 19 is placed near the dial, and the analog movement is located at the lower left of the module, and in order to have the crown 19 in the 3 o'clock direction, the winding stem 20 must pass through the digital part. For this reason, Reuse 19 is provided at the 8 o'clock position. For this reason, it is inconvenient that you have to operate the Reuse 19 with your left hand or with your right hand by turning the clock display upside down.However, it is a crystal oscillation type electronic clock, and the time can be adjusted using a digital display. Since the correction is made in conjunction with the second return to zero, there are very few chances to make corrections, such as during the initial set or when adjusting the time difference when traveling abroad, so operability is not a big problem. Rather, it is easier to understand and operate without confusion if the correction member is placed close to the display. Furthermore, from the design of the module, it is most reasonable to place the reuse as a member that mechanically corrects the analog part on the outer periphery of the module where the analog movement is located.
This contributes to making watches thinner and smaller.

The winding stem 20 is located in the 8 o'clock direction and faces the center of the module, and is located at the center of the dial 17, that is, the minute hand 28.
a, a cylinder pinion 26 to which the hour hand 28b, etc. is attached;
The coordinates of the hour wheel 27 are not located on the extension line of the winding stem 20. Therefore, there are fewer restrictions on the stroke of the winding stem 20, making it possible to take a larger stroke, which facilitates the design of the so-called back portion.

The dial 17 and the main plate 32 have two screws 18A,
18B, one screw 18B is located near the short side of the liquid crystal cell 11 on the side where the notch is located and approximately at the center of the length of the short side, and the other screw 18A is located near the short side of the liquid crystal cell 11. They are each arranged near the long side of the side where the notch is located and at a position near the approximate center of the length of the long side. In other words, according to the above configuration, the screws 18A and 18B are located on a straight line passing through the central axis of rotation of the pointer, which is the center of the pointer display section, so that the pointer display section does not tend to tilt.
Can be firmly fixed. Further, the dial plate 17 has a protrusion 17 along the hexagonal shape of the analog display frame 10c.
A is provided. The concave part 17b surrounded by the protruding part 17a and having a concave cross section (step diagram not shown) is the space for the pointer to rotate, and the thickness of the dial 17 in this part is made as thin as possible. By this, the dial 17 and the hands 28a, 2
A large gap with 8b is provided to prevent problems such as needle scratches. On the other hand, the outer extension 17c of the protrusion 17a is thick because it is not a part to which the hands 28a and 28b are attached. Since it is difficult to form the dial 17 with such a complicated shape by machining, it is necessary to rely on molding of plastic or electroforming of metal such as copper. Therefore, from the viewpoint of moldability or strength, it is important to increase the thickness of the dial 17 as much as possible. Especially the screw 18 that fixes the dial 17
Since the positions of A and 18B are relatively far apart, it is extremely effective to increase the thickness of the dial 17 of the hexagonal protrusion 17a and its extension 17c in order to prevent the dial 17 from deforming due to drop impact. It is a means.

[Effect of idea]

As described above, according to the present invention, by providing a notch in a part of the electro-optical display and housing the pointer display in the notch, Since the area of the electro-optical display section can be increased, more display patterns can be formed, and the displayed contents can be more satisfactory. Furthermore, by using the same dividing member for both displays, the analog display has a more unified feel.
A digital dual display clock can be constructed. Furthermore, even if the electro-optical display section and the pointer display section are placed close to each other, each display section can be fixed at an optimal position to prevent it from tilting, so that both analog and digital displays as in the present invention can be used. The clock can be realized.
