Description

[Detailed Description of the Invention] The purpose of the present invention is to make the operation of a multi-function watch such as the chronograph function of an analog quartz easier to understand, and in particular, the connection between the electronic circuit and the mechanism is difficult to understand during actual user operation. The purpose is to prevent confusion.

In recent years, with the advent of digital electronic clocks and the increased integration of electronic circuits, stopwatches are now equipped with a sprint function (previously displayed as a lap function; a function used to measure elapsed time), as well as a simple integration function. It has become possible to measure

Chronograph watches with a mechanical pointer display usually use a heart cam to reset the chronograph hand position, but the mechanism is complicated, and analog chronographs with a split display usually use a heart cam to reset the hand position. Nothing other than a type-style hanging clock has been realized.

In conventional digital systems, when the chronograph is operated using two buttons, the start/stop button and the lap/reset button, the user does not know what is being measured even when looking at the numbers on the display, so it is usually During measurement, some kind of operation mode display, such as LAP (split) display, is displayed.

Here, in the present invention, these operations are simple and easy to remember,
In some cases, the correspondence between the operation method of an external operation member that can be operated even without a split display and the electronic circuit will be explained in detail.

FIG. 1(a) is a circuit block diagram showing one embodiment of the present invention, FIG. 1(b) is an explanatory diagram of a switch showing a part thereof, and FIG. An example of a layout diagram is shown.

In FIGS. 1 and 2, the analog quartz time section includes a time standard 1, a frequency dividing circuit 2, a motor drive circuit 3,
The time motor 4 and the time display 5 are usually a clock 50 and a minute hand 5b.
- It consists of a second hand (here 5a), etc., and is well known. In this example, it is assumed that the chronograph function uses independent motors. A switch 6 on the winding stem and a switch 7 on the button part as external operating members.
9, switch control circuit 10, 16.17.1 days as an electronic measurement circuit for chronograph measurement, the contents of which are time counter 11.41.51, latch circuit 12.42.
52, - consists of a number configuration circuit 13, 43, 53, a hand position counter 14, 44, 54, a drive control circuit 15, 45, 55, etc. Compared to the measuring circuit of a digital watch, the hand position counter 14. 44.54 will be added.

The switches 30, 40, 50 distribute signals corresponding to each of the frequency divider circuits 2 to the time counters 13, 43, 53 according to the signals from the switch control circuit 10.

The motor drive circuits 19, 22, and 25 are each independent,
Chronograph motor A20 and motor B corresponding to each
, the motor C26 is driven, and the chronograph display A21, display B24, and display C27 each have a different chronograph measurement digit, and the chronograph display with different digits is displayed as an independent display hand.

Here, for example, chronograph display A21 is 1 rotation 1
Assuming that the hand moves in steps on a scale divided into 10 seconds, this display allows measurement of 1/10 seconds, and although the chronograph display B24 is located at the center of the watch, this hand position is The position can also be changed to the small second hand 5a for a watch. The speed of one revolution is one minute, which is the same as the movement of the second hand, and if the scale is divided into 60 parts, it is possible to measure and display the second digit of one revolution. The chronograph display C27 is set at 30 minutes per rotation, and when the hand is displayed in steps of 30 divisions, the minute digit can be displayed up to a maximum of 30 minutes, and this maximum value can be changed to the 60 minute hand etc. by changing the number of division steps. Changes are possible. Therefore frequency divider circuit 2 to electronic measuring circuit 16.17.18
The input signal from the input signal is a frequency-divided signal corresponding to each measurement digit.

Since measurement and operation of electronic circuits are not the main purpose of the present invention,
This section mainly provides explanations regarding switches and operations. The switch 6 described here works in conjunction with the winding stem, and depending on the pulled out position of the winding stem, the first stage normal carrying position is 6a, the switch input is at 6b when pulled out and the second stage is pulled out, and the switch input is set at 6b when the switch is pulled out and the third stage is pulled out.
C, and whether the switch is open or closed is uniquely determined at that position. For switch 6, switch 7.
8.9 is omitted here because it consists of a push button, etc., but the moment you press it with your finger, it turns on electrically as a switch.
However, the moment you release your finger, the switch itself turns OFF (open) due to the spring force of the coiled spring on the button part of the switch or the lever of the movement.
An example of a so-called fish-type switch will be described.

(i) Switch 6 when the winding stem is in the first stage position 6a
An outline of the operation of switches 7.8.9 will be explained below.

In a circuit in which a part of the switch control circuit 10 shown in FIG. 1(b) is enlarged, when the switch 6 is in the open position 6a (
When the circuit is positive ground), switch 6 is L.
Since the output of the gate 31 is Low regardless of whether the other input of the AND gate 31 is low, the AND gates 7a and 8a.

9a is in the High ready state, and switches 7.8.
When 9 is input, gate 7a outputs DZ through D type flip-flop (hereinafter abbreviated as FF) 32, D11 gate 8a outputs DZ, and gate 9a outputs D3.

(ii) Next, the outline of the second stage of the winding stem and the position of the switch 6b will be explained.

Take switch 6b (that is, set it to positive High),
The signal of the switch 6b is controlled via the gate 31 according to the High and Low outputs of the gate 7. When Dl is Low, the gate 31 becomes High, and the gate
a, 8a, and 9a do not operate because the input part becomes Low,
Games 1-7b, 8b, and 9b are in a ready state. If switch 7.8.9 is turned on in this state, the output will be 7.
b outputs E, 8b outputs E, 9b outputs E3. The signals E, , EZ, E, each pass through the drive control circuit 15 of the electronic measuring circuit 16.17.18 of FIG. 1(a) and provide independent signals to the motor drive circuit 19.22.25. (iii) The switch 6 (indicated by a single dotted arrow) can also take the open position 6C (the state in which the winding stem 6 is pulled out to the third stage in FIG. 2). switch 6
At c, it is in the open position, and at this time the chronograph operation is exactly the same as switch 6a in (i), so switches 7, 8, and 9 at this time are the same as in (i). D
, , D3 are being output.

(iv) The relationship between the chronograph hand and the time display hand when the switch as a winding stem passes through 6a, 6b, and 6c will be described.

(v) An example will be described in which the functions of the second and third stages of the winding stem are all performed in the same second stage.

Here, each position of the winding stem 6 as a switch of the external operation member in the present invention and the operation/operation and display of the switch 7.8.9 will be explained in detail in each item (i) to (V). explain.

First, as a clock that tells the normal time, there is a well-known analog quartz as explained in Figure 1 (a), and the time standard 1,
A signal waveform-shaped by the motor drive circuit is outputted based on the signal from the frequency dividing circuit 2, and the time motor 4 rotates to display the time on the time display 5.

In Fig. 2, 5a is used as the small second hand for the time display, and
A minute hand 5b and an hour hand 50, which are the same as those of a normal watch, are shown in the center.

Next, switch 6 is used to operate the chronograph. Normally, the switch is idle at the second position 6b when the winding stem is pulled out one step to correct the hour and minute hands of the time display 5, and The third pulled-out position 6C is the correction position of the time display 5 described above, and the switch 6C is configured to be open. When the winding stem is rotated to the left or right at position 6c, the hour and minute hands are adjusted via a switching mechanism (not shown).

(φ) The switch 6 is open in the normal carrying position 6a where the winding stem is pushed in. Switch control circuit 10 accepts the signals of switches 7.8.9.

Here, switch 7 is for starting and stopping the chronograph, switch 8 is for resetting the chronograph, and switch 9 is for starting and stopping the chronograph.
functions separately from the chronograph's split measurement function.

In the state of the switch 6a, when the switch 7 is pressed to make it positive, the input of the AND gate 7a becomes High in FIG. 1(b), and the output of the gate 7a is input as the FF32 clock input. The signal as the output Q of F-F32 becomes High once the first clock input is input, and remains High until the second clock input.
ght continues, becomes Low by the second input, continues to be Low until the next third clock input is input, and becomes High only when the third clock input is input. That is, the clock input of F-F is input by connecting switch 7, and when switch 7 is turned on, F-F clock input is input by connecting switch 7.
- When the output DI of F32 is in High state, it is in the hand movement state for chronograph measurement, and when D is Low, it is stopped as a chronograph, that is, in the stop state, and the operation of button 7 is the start/stop state of the chronograph. This will send out a signal that repeats.

When the switch 7 is pressed to start the chronograph (hereinafter abbreviated as CG) with the switch 6- open and the switch 6a open, the signal trigger activates the switch 30 shown in FIG. 1(a) and starts the time counter 11. , the motor drive circuit 19 and the motor A20 are operated via the drive control circuit 15, and the chronograph display A21, for example, one step 0.
1 sec.

Measurement of detailed measurement time such as 1 rotation of 1 sec, where one rotation is 1 sec or less, starts. At the same time, the measuring circuit 16 starts operating the needle position counter 14 and the like.

Next, to stop the CG, turn switch 7a to H again.
When set to light, a signal from the switch control circuit 10 stops the time counter 11, stops the rotation of the hands on the display 21, and displays the hand position at the time of stop.

Next, the operation of switch 8 will be explained.

The switch 8 has a reset function as a CG, and when the switch 8 is pressed to High, the output D2 of the control circuit 10 resets the time counter 11 and the hand position counter 14 to 0, and also operates the drive control circuit 15, and displays the display A.
The 21 hand will fast forward to the 0 position. In other words, the electronic measuring circuit is set to d, and at the same time, the mechanical display hand 21 is fast-forwarded to 0. However, since this fast-forwarding is all processed electronically, this electronic circuit was originally
You can only fast forward to the memorized location.

Therefore, in Fig. 2, if the hand 21 starts from a position that has deviated from 0, the amount of rapid feed when reset by a signal from the electronic circuit will be reset by regarding the position deviated from 0 at the start as O. Ru.

In other words, when talking about correcting the 0 second position of the chronograph,
The display positions of the chronograph hands 21, 24, and 27 in FIG. 2 are as follows, in order to operate the electronic circuit explained in FIG.
For example, if a battery is used as a power source, considering when replacing the battery, in the case of a normal wristwatch that does not use an electrical memory means or other power source to back up the battery,
After replacing the battery, the electronic circuit can be started arbitrarily (2), or (2) the entire circuit can be reset to start from zero.

In either case, the chronograph hand 21.24 in FIG.
．． If the battery is replaced while the chronograph 27 is stopped at an arbitrary position, the start of the electronic measuring circuits 16, 17, and 18 and the position of the chronograph hand 0 will be misaligned. Therefore, a chronograph display hand position correction function is required to match the mechanical start position of the hand 21 with the electronic start (reset) position. This matter will be explained in detail in (ii) after the next split function.

When the switch 9 as a splitter is operated during CG measurement, that is, while the switch 7 is starting, the signal D3 sent through the switch control circuit 10 causes the 9 latch circuit 12 to start the time counter 11 until the next D3 signal is input. Holds the value of . The value of the needle position counter 14 is determined by the latch circuit 12.
When the value matches the value of , the drive control circuit 15 operates to temporarily stop the motor 20 based on the output from the match detection circuit 13, and the display hand 21 of the chronograph is temporarily stopped. However, CG as an electronic circuit
Measurement is continued by the time counter 11. When the split switch 9 is operated again, the latch circuit]2 is released based on the D3 signal, and the signal from the time counter 11 is passed.

The drive circuit issues a fast forward drive signal until the value of the hand position counter 14 matches the value of the time counter 11.
The chronograph display hand 21 will catch up to the previous measurement time.

Although only the movement of the chronograph hand 21 has been described in detail here, the electronic circuit group constituting the CG measurement circuit 17.1, the related motor parts 22, 23, 25, 26, and the hands of the chronograph display 24.27 is switch 7.8.9
, the display hand 21 operates in the same manner as the display hand 21, except that the drive cycle is different, and a CG display is performed.

(ii) The position of the switch 6b as a winding stem (chronograph display hand position correction function) will be explained.

When the switch 6 serving as a winding stem is pulled out and placed in position 6b, the AND gate 31 is operated and the signal D1 indicating the chronograph operating state input to the AND gate 31 becomes High.
From ht and Low, the output of switch 6 becomes Low and Htg.
Since it is possible to take the ht signal, first of all, if we consider the time when the DI double signal is High while the chronograph is operating, even if the switch 6 is closed during chronograph measurement, that is, the winding stem is pulled out to 6b, the chronograph will not operate. Therefore, the state is no different from the state of the first stage of the winding stem. This matter will be discussed in detail later in section (iv).

When the chronograph has stopped and the case symbol becomes Low,
Since the gate 31 outputs the signal of the switch 6b as it is, the switch 6b outputs the closed High1a'' state to the gate 31.
It will be output from. In the following explanation (iv), we will explain that pulling out the winding stem to the second stage is done when the switch is set to 6b with the chronograph stopped at the first stage of the winding stem, and when the switch is closed. do.

When the switch 6 as a winding stem is pulled out and the switch is closed in position 6b, the chronograph hands 21, 24, .
The O position of 27 is a position that can be corrected. When the switch 6 is in the closed (High) state, as explained in FIG. 1(b), E,
, E2, and E3 signals are output.

Here, switch 6 is closed (position 6b) in Fig. 1(a).
Then, the output S of the gate 31 becomes Htgh of the switch 6.
Since the t state is output as is, the time counter 11.41.51 is reset through the OR gate 56. When the time counter 11.41.51 is reset, the drive control circuit causes the motor to advance rapidly until the hand position counter 14.44.54 matches the state of the time counter and the state of the hand position counter and the time counter. The motor will stop when they match. the result,
The amount of deviation between the position of the pointer and the zero position of the scale can be clearly noted. If the pointer position and the zero position of the scale are out of alignment, use switch 7.8.9 to correct it by the necessary amount. Assuming that the pointer position of the chronograph display A is now off, the switch 7 is turned on to drive the chronograph motor 20 through the drive control circuit 15.

At this time, the output of the switch 7 is connected to the reset terminal R of the needle position counter 14 (not shown), so every time the switch 7 is activated, the needle position counter 14 is reset and the motor is driven. In this case, the needle position counter remains at zero position.

That is, by temporarily turning on the switch 7, the control circuit 10 outputs the signal E, and inputs the high frequency signal of the frequency divider circuit 2 to the motor drive circuit 19 via the drive control circuit 15. Therefore, the motor A20 rotates at the same speed or faster than when driving the chronograph, or by inputting a signal of one step rotation per operation of the switch 7 to the drive circuit 19, as a result, the chronograph The position of the display hand can be corrected by displacing the display hand by one step or by driving it at a higher frequency. In this way, the display hand 21 corresponds to the switch 7, and the display hand 24 corresponds to the switch 8.
In response to the switch 9, each of the display hands 27 can be independently adjusted to the O position of the chronograph or any other position. After determining the mechanical position of the hand in this way, the switch 6 is opened again (Low) to match the O position of the electronic circuit, and at the same time, the switch control circuit 10 sets the D2 signal to High and starts timekeeping. In order to reset the measurement circuit 16 including the counter 11,
All electronic circuits are in the reset O state. The chronograph is now ready for use again. If the switch operation and electronic circuit operation cannot be matched in this way, there will be no clear separation between chronograph measurement and hand position correction using the switch, so if the CG display hand shifts, remove the back cover and take out the movement. Either reinstall the needle or completely memorize the operating procedure and press switch 7.
．． It is extremely difficult for general users to understand, as it requires a combination of 8.9 or a distinction between CG operations and hand position corrections that utilize so-called time differences, such as pressing and holding the switch 7 to bring the correction mode into effect.

In the method of the present invention, the return from the hand position correction state to the chronograph operable state and the return to the chronograph usable state are determined by the opening 6a of the switch 6 (the state in which the switch 6 is pushed in in FIG. 2). Correspondingly, this is extremely easy to understand, and the method of using the above-mentioned time difference for CG restoration to which the present invention is not applied is difficult to understand as an operation.

(iii) The operation of the switch 6 (here, as the winding stem 6) at the third stage pull-out position 6c will be explained.

At the position of the winding stem 6c shown in FIG. 2, the winding stem has a function for correcting the hour hand 50, the minute hand 5b, a well-known regulating mechanism for regulating the second hand 5a, and the time shown in FIG. In order to accurately adjust the time, the frequency dividing circuit 2 has a function of resetting a part of the frequency dividing circuit 2 that is involved in time display.

Here, the operation of switches 7, 8, and 9 in the switch 6C position basically may be either (i) or (ii), but here, the chronograph measurable state is the same as in (i) when switch 6a is open. In this case, the measurement circuits 16, 17, 18, etc. are all in the same state as in (i) and will therefore be omitted. Winding stem 6C
Adjust the second hand 5a at the position , and after completing any time adjustment using the hour hand 50 and seconds 5b, push in the winding stem 6C to return it to the position 6a. During this short period of time, 6b passes, but at that time,
Unless input is made to switches 7, 8, 9, there is little chance that the chronograph hands 21, 24, 27 will be in the corrected state at the switch 6b position, so the second hand 5a will move accurately at the same time as the winding stem 6c is pressed. This allows the clock to be set accurately.

(iv) Here, we will explain in detail how the relationship between the chronograph hand and the time display hand when the winding stem is pulled out and pushed into each of the positions 6a, 6b, and 6c is related to the circuit switch.

Already switch 6 and AND gate 31. The relationship of FF32 has been described in (i) and (ii). In other words, the signal D1 when the chronograph is in operation is HIGH, stops and stops,
Considering the signal as LOW, when the winding stem is pulled out from the 1st stage to the 2nd stage (6a → 6b), there will be no output from the AND gate 31 even if it becomes 2b while the chronograph is moving. The operation and characteristics when the chronograph hand does not enter the corrected state described in ii) but enters the corrected state are described in detail in (ii).

When the winding stem is pulled out to the third stage without entering the corrected state at the second stage of the winding stem, the switch 6C is LOW, and the gate 7a is activated in order to uniquely set the output of the AND gate 31 to LOW. The chronograph continues to operate as usual. However, here, (iii
), the second hand for time display is stopped and calibrated, and hours and minutes can be adjusted. In other words, even if the winding stem is pulled out in this way, the chronograph will not stop at the second or third winding stem. Therefore, at the second stage of the winding stem, there are two states: when the chronograph hand does not stop, and when it stops and the CG hand can be corrected. In this way, 2
The characteristics of the chronograph not stopping in the third and third stages are as follows.

When setting the analog chronograph clock to the hour, first listen to the time signal while the winding stem is on the first stage, and at the same time press the chronograph switch 7 to set the chronograph to the hour and start. In other words, the second hand of the chronograph is on the hour. From this state, move the winding stem to the second stage and then to the third stage to adjust the time. (However, when pulling out to the third stage, the second hand 5a for the time can be placed at any position, not at the O second position.) After slowly setting the hour and minute hands to the current time in the third step, when the chronograph second hand 24 matches the second hand 5a, push the winding stem from 6c to 6a, and the second hand 5a becomes the chronograph second hand. This means that you can move the seconds accurately and set the time at the same time.In the case of conventional analog quartz watches, in order to synchronize with the hour signal, you must first move the second hand until it reaches the 0 second position. , you have to pull out the crown, correct the rotation of the hour and minute hands, wait until the hour signal is heard, and push in the winding stem. If the clock is advancing, you can wait for the time signal and set it, so it is relatively easy. However, if the clock you are trying to set is behind the hour, you will need to wait about a minute, and in reality, the time signal will sound first, so unless you have another reference clock, you will not be able to set it accurately. It takes more than a few minutes.The main feature of this PAT is that it can be set to any time of your choice, as the chronograph's second hand is used as a reference clock to start according to the time signal.

Furthermore, in order to realize an analog chronograph watch,
When the chronograph second hand presses the button after using the chronograph, the circuit memorizes it and automatically returns it to the original time.It may seem simple at first glance, but the electronic circuit constantly counts the amount of chronograph operation. However, since a memory for the current time is also required, complex electronic circuits such as counters and coincidence detection circuits are required, making it unsuitable for small, low-power devices such as wristwatches. It is not as simple as an invention, and must be done in the same way as conventional analog quartz. As in the present invention, the second hand 5a for normal time and the second hand 24 for chronograph are separately motorized.
If you configure the wheel train so that the movement of the chronograph's hands does not stop even when the time is adjusted, you can use the chronograph while constantly checking the correct time, both in terms of circuitry and in terms of use.
It has the advantage of being extremely easy to set the time. In this FAT, we have described an example in which CG hand alignment is prohibited during chronograph hand movement, but if it is not necessary to move the CG hand on the second stage of the winding stem, set the winding stem to 6b while the CG is stopped, or Although it is easy to imagine a circuit configuration in which pressing the switch 7 even in the 6b state stops the CG and makes it possible to correct the CG, this is not the main purpose of the present invention and will therefore be omitted.

In addition, in the present invention, the adjustment of the chronograph hand position is included as an operation on the second stage of the winding stem, so the explanation is difficult to understand, but normally when changing the time from CG hand movement on a mobile phone, ■ Stop the CG or change the hand movement. Should I leave it as it is?

■ Even if the CG is temporarily stopped, the CG is turned off again in the time adjustment state.
Should I enable G hand movement?

It can be summarized into two states.

I have been proactively talking about ■. As for (2), the CG hand can be moved regardless of the time setting, and the CG hand can be controlled, so it has the same effect as (2).

(V) In the explanation so far, in order to make it easier to understand, the winding stem is divided into the first, second and third stages, with the second stage 6b being CG correction and 6C being time correction.

It is also possible to have the 2nd and 3rd stages together, and this is the state at that time. Describe the operation.

When the winding stem is pulled out to the first stage, the time is corrected by rotating the winding stem 6b, and the hour and minute hands 5 are corrected by mechanical rotation correction, similar to the well-known analog quartz, and the second hand 5a is also corrected and then stopped.

At the same time, the switch 7.8°9 is involved in the correction of the CG hand in the same way as described in (ii). However, the drawback in this case is that the CG hand correction and time correction are not independent, so when you try to correct the CG hand, the time always stops.
This will cause the time you have set to be incorrect.When setting the time accurately, first turn the CG hand from winding stem 6a to 6b.
After adjusting the position, the winding stem is temporarily returned to 6b → 6a, the CG seconds are set at the hour, and the hands are moving, and then the winding stem is moved from 6b → 6a again to set the time seconds and CG seconds. Although it must be aligned by pushing,
If the calendar is not attached to the second winding stem, this is a method that can be produced at low cost.

Here, in the present invention, a description will be given of how to effectively arrange the operation switch group of the chronograph.

In Fig. 2, when switch 7 is operated to start/stop, switch 8 is operated to reset, and switch 9 is operated to split (or lap) as CG operations, in a conventional general electronic clock like this, in a digital clock, There is one start/stop switch 7 and a switch 8 where the stop switch 8 is also used as a sprint function.
However, when using a digital liquid crystal panel, etc., the user can immediately know the operation by displaying the current operation status on the panel, but split operations etc. are usually extremely difficult to understand. be. In the present invention, by separating these difficult-to-understand contents into operation switches, ordinary simple stopwatch operations can be covered by button operations as a side switch on the right half of the watch, and the complicated functions of the split can be avoided. They are arranged in positions that are suitable for those who want to use them, or those who can use them to measure first and second places, etc., as long as they are understood and used. The split buttons are independent in this way and arranged on the left side of the watch to prevent accidental operation, so if you don't need the split function, you can leave switches 7 and 8 as they are and remove the button 9.

Furthermore, since the chronograph is located on a side different from the right side of the watch that is normally used, it is possible to provide a chronograph with less risk of erroneous operation.

As already detailed in the adjustment of the position of the CG hands, each display hand can be adjusted independently in response to each button as an external operation member, so there is also the operational advantage of being able to adjust the chronograph hands extremely easily. At the same time, when a watch is disassembled and repaired at a general watch store, the CG hand is installed, and when the second hand is installed, the scale shift and the upper and lower tilt of the hands can be changed. This is easy because you can feed the needle according to the switch operation. In addition, by performing this operation, if we consider the hand correction state as a counter state rather than a chronograph timepiece, as explained in detail in the main text for each of the display hand 27 and display hand 21, switch (button)
By pressing operations 9 and 7, the display hands can be used as multiple counters by independently rotating the display hands by one step each time the buttons are pressed.

Therefore, by providing an analog chronograph timepiece with the operation and correction functions of the present invention, a chronograph with a counter function can be easily realized.

Also, when adding a calendar function to the 00 function,
In the second stage of the winding stem, the functional calendar correction machine of a general analog watch remains the same, and the electric circuit switch of the present invention can be easily added, so that in the third stage, the calendar can be adjusted at the same time as a general analog watch. Coupled with the ability to adjust the time, it is extremely common to use conventional 1st stage mobile phones, 2nd stage mobile phones, etc.
The function added to the third stage has been modified, and the winding stem can be operated in the same way as the third stage time setting watch, so there is no strange feeling, and retailers and users can operate it without any confusion.

According to the configuration of the present invention, there is provided a time standard 1, a frequency dividing circuit 2a, a first motor for normal time display that operates based on the output signal of the frequency dividing circuit, and a plurality of second motors for displaying other machines. a motor, a normal time hand 5a driven by the first motor;
5b, 5c, a plurality of multifunction hands 21, 24, 27 each operated by the plurality of second motors, elapsed time counting means 16, 17, 18 provided as the other function, positioning in multiple stages in the axial direction; a first switch 6 which operates in conjunction with an external operating member and takes at least the normal hand movement position, the multifunction correction position, and the normal time correction position along the pulling direction of the external operating member; and a first switch 6 that controls the elapsed time counting means. A plurality of second switches 7.8, 9 that output signals
, outputting start and stop signals for the elapsed time counting means in response to an input signal of the second switch when the first switch is at the normal hand movement position, and when the first switch is at the multi-function correction position. a switch control circuit 10 that outputs a signal for individually operating each of the plurality of second mokes in response to an input signal of each of the plurality of second switches and setting a desired position of the multifunction hand;
By providing means 6c and 2a for resetting the frequency dividing circuit when the first switch is in the normal time adjustment position, the following effects can be obtained.

(a) As watches become multi-functional, the number of motors and the hands driven by them increases, and the correspondence between the hands and correction switches becomes unclear, complicating operations.

However, in the configuration of the present application, a plurality of switches are used to control the start and stop of the multi-function elapsed time counting means, etc., to correct the desired position of the multi-function hand, and each switch operates a different motor to control the elapsed time counting means. To provide an easy-to-operate analog multifunction timepiece by reducing the number of external operation buttons and clarifying the correspondence between the correction switch and the corrected hands, since the multifunction hands are independently corrected. (
b) The first switch takes the normal hand movement position, multi-function correction position, and normal time correction position along the direction in which the external operating member is pulled out, so the multi-function display can be performed without affecting the position of the normal time hand. To provide an analog multi-function clock that allows for correction and is easy to use in practice.

l! l e-procedural amendment (voluntary) 2. Name of the invention Analog multi-function watch 3. Relationship with the person making the amendment Applicant 2-4-1 Nishi-Shinjuku, Shinjuku-ku, Tokyo (236) Representative Director of Seiko Epson Co., Ltd. Tsuneya Mura Procedural amendment to the specification (scope of claims/detailed description of the invention) and the scope of claims are amended as shown in the attached sheet. , from page 28, line 9 to page 30, line 10 of the specification, the structure of the present invention is provided. ” and insert the following. "According to the configuration of the present invention, a time standard, a frequency dividing circuit, a motor that operates based on the output signal of the frequency dividing circuit, a pointer operated by the motor, an elapsed time counting means interlocked with the pointer, The first step is to select the hand movement state and pointer correction state.
a second switch that outputs a signal for controlling the elapsed time counting means; a second switch that outputs a signal for controlling the elapsed time counting means; and a second switch that outputs a signal for controlling the elapsed time counting means; In addition to outputting a start or stop signal, when the first switch is in the pointer correction state, the elapsed time counting means is set to the first stage state, and the motor is operated in response to the input signal 2 of the second switch to adjust the pointer. Since the analog multifunction watch is equipped with a switch control circuit that outputs a signal for setting the initial position of the watch, the following effects can be obtained. That is, according to the present invention, as described above, the switch control circuit connected to the first switch and the second switch performs start/stop control of the elapsed time counting means on the second switch in the normal hand movement state by switching the first switch. In addition, in the pointer correction state, the second switch generates an input signal to change the position of the pointer, and in the pointer correction state, the elapsed time counting means is set to the initial state, so it is possible to count the elapsed time with a small number of switches. It has the advantage that even if the position of the pointer and the pointer are matched, accurate elapsed time display can be obtained at all times. ” An analog multi-function watch claimed in the above claims.
