Abstract

PURPOSE:To prevent the disturbance in the coupling particularly between electronic circuits and mechanical systems during the actual operation by the user, by making a timepiece having multiple functions including a chronograph function in analog quartz easier to operate. CONSTITUTION:When the user starts a chronograph (CG) by pressing a switch 7 while a switch 6 is open, a signal D1 operates a switch 30 to start a clock counter 11, and a motor driving circuit 19 and a motor A20 are started by a driving control circuit 15, then the measurement of the fine measuring time is started. A switch 8 is a reset function in CG, and when the switch 8 is set to High t, the output D2 of a control circuit 10 resets the counter 11 and a hand position counter 14 at 0, and operates the circuit 15 so that the hand of a display A21 is fast fed to a 0 position. If a switch 9 as split is activated, a latching circuit 12 is operated by a signal D3 with a switch control circuit 10, and the circuit 15 operates to stop temporarily the motor 20, thereby holding the display hand 21 of the chronograph stopped temporarily.

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 in an analog quartz easier to understand, and in particular, the connection between the electronic circuit and the mechanism may be confusing during actual user operation. The purpose is to prevent this.

In recent years, with the advent of digital electronic clocks, and the increasing integration of electronic circuits, stopwatches are no longer just counting.
It has become possible to measure the split function (previously displayed as the lap function, a function used to measure elapsed time).

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

When operating a chronograph using the start/stop button and the lap O reset button on a conventional digital 2G, 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 display, such as LAP (8prit) display, is displayed.

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

FIG. 1 is a circuit block diagram showing one embodiment of the present invention.
Figure Cb) is an explanatory view of a part of the switch, and Figure 3 shows an example of the arrangement of the external operating member and the display hand.

In FIG. 1, the analog quartz time section includes a time standard 11 frequency divider circuit 2. The motor drive circuit 3, the time motor 49, and the time display 5 are usually composed of an hour hand, a minute hand, a second hand, etc., and are well known. In this example, it is assumed that each chronograph function uses an independent motor. Switches 6.7, 8, 9 as external operating members. Switch control circuit 10, 1 as an electronic measurement circuit for chronograph measurement
6.17.18, this content is the time counter 119
Latch circuit 12. Coincidence detection circuit 13. Needle position counter 1
4. It consists of a drive control circuit 15 and the like, and a hand position counter 14 is added compared to the 1tll 1lQ11 circuit of a digital watch. The motor drive circuits 19, 22, and 25 are independent, and the corresponding chronograph motor A20. Motor B23 and motor C26 are driven to display chronograph display A219 and display B24. Each display 027 uses a different chronograph measurement technique and displays a chronograph with different digits as independent display hands.

Since the measurement and operation of this electronic circuit is not the main purpose of the present invention, the explanation will mainly be given regarding the switches and operations.

The external switch 6 is a switch for switching between normal chronograph operation and correction of the display hands of the chronograph displays 21 to 27. Switch control circuit 10 illustrated in FIG. 1Cb)
In the circuit that enlarges a part of , when switch 6 is open (the circuit is connected to positive ground), switch 6 is L
Since it is OW, AND gates 7a and 84.9a are H.
light is in the preparation state, and when switch 7.8.9 is input, DI is output from gate 7α, and D2 is output from gate 8α.
, D3 is output from the gate 9a.

Next, close switch 6 (i.e., positive Hlght (
gates 7α and 8α19α do not operate because their inputs become bows, and gates 74 and 84 do not operate.

9b is in the ready state. In this state, switch 7.
When 8.9 is input, the output is El from gate 7b, E from 8h, and E3 from 9A.

Here, the setting operation will be explained with reference to FIG. 2 showing the front appearance of the chronograph timepiece of the present invention.

First, the well-known analog quartz clock explained in Fig. 1(a) is used as a clock to know the normal time, and the signal from the time standard 1s frequency divider circuit 2 (from which the signal whose waveform is shaped by the motor drive circuit 3 is outputted and the time The motor 4 rotates, and the time display 5
Display in . In FIG. 2, a sub-second hand 5a, a minute hand 5b, and an hour hand 5C are shown.

Next, for chronograph operation, switch 6 is used. Normally, the switch is closed at the second position N6b when the winding stem that adjusts the hour and minute hands of time display 5 is pulled out one step, and then pulled out another step. The sixth stage position 6C is configured as a correction position for the time display 5 mentioned above. That is, when the watch is rotated left and right at the 6C position, the hour and minute hands are corrected via a switching mechanism (not shown).

The switch 6 is open in the normal carrying position when the winding stem is pushed in. The switch control circuit 10 is a switch 7.8
．． Accept 9 signals. Here switch 7 is the start/stop of the chronograph.

Switch 8 has a separate function for resetting the chronograph, and switch 9 has a separate function for split measurement of the chronograph.

When the switch 7 is pressed to start the chronograph (hereinafter abbreviated as OG) while the switch 6 is open, a signal is generated, which activates the switch 30, starts the time counter 11, and controls the motor drive circuit 19 via the drive control circuit 15. ．． Motor A2
0, chronograph display A21, here, for example, 1 step 01 sec 1 rotation 15eC of the display hand, etc.
Rotation is 11. Detailed measurement of time less than ec starts. At the same time, the measuring circuit 16 detects the needle position counter 14.
etc. have started their respective operations.

Next (to stop the OG), when the switch 7α is set to HLght again, the signal from the switch control circuit 10 stops the time counter 11, stops the rotation of the hand on the display 21, and displays the stop signal. do.

Next, the operation of switch 8 will be explained. Switch 8 is a reset function for CG, press switch 8 to Hlg
ht, the output D2 of the control circuit 10 is output from the time counter 11. The needle position counter 14 is reset to 0, and the drive control circuit 15 is activated so that the needle on display A21 moves to fast forward υ.
Then it gets to the 0 position. In other words, when the electronic measuring circuit is set to 0, the hand 21 on the mechanical display is fast-forwarded to 0. However, since this fast-forwarding amount is all processed electronically, this electronic circuit is originally Therefore, if the hand 21 starts from a position where it has deviated from 0 in Fig. 2, the amount of fast forwarding when reset by the signal from the electronic circuit will be the same as at the start. The position that deviates from 0 is regarded as 0 and is reset. In other words, the 0 second position of the chronograph is corrected (to be specific, the position of the hook display of the chronograph hands 21, 24, 27 in Fig. 2 is the same as that in Fig. 1). In order to operate the electronic circuit described, for example, if a battery is used as a power source, and when replacing the battery, in the case of a normal watch 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 by (1) starting arbitrarily, or (1) resetting the entire circuit so that it starts from 0. In either case, Chronograph buttons 21 and 24 in Figure 2
, 27 is stopped at any position and the battery is replaced, the electronic measuring circuit (i) 6 , 17 ,
The start of 18 and the 0 position of the chronograph hand are misaligned. Therefore, a display hand position correction function is required to match the mechanical start position of the hand 21 with the electronic start (reset) position. More on this after the next split feature.

When the switch 9 as a splitter is operated during the 0Gtl' measurement, that is, when the switch 7 is starting, a signal is sent through the switch control circuit 10 and the latch circuit 12 is output from the G.
The drive control circuit 15 operates to temporarily stop the motor 20, and the chronograph display hand 21
is temporarily stopped. However, the OG measurement as an electronic circuit is continued by the time counter 11. When the split switch 9 is operated again, the drive signal is output until it matches the signal from the time counter 11, so that the chronograph display hand 21 catches up to the previously measured time.

Although only the movement of the chronograph hand 21 has been described in detail here, the CG measurement circuit 17.18 and the related 22.
23, 25, 26 motor section and chronograph display 2
The 4.27 hand operates in the same way as the display hand 21 by operating the switch 7°8.9 to display OG.

Here, the operation of the above-mentioned display hand position correction function will be explained.

Pull out the switch 6 that serves as the winding stem, and when it is in position 66, the switch is in the closed state (when rubbed, the chronograph hands 21, 2
4.27 O position is a position that can be corrected. switch 6
In the closed (Hlght) state, as explained in Fig. 1Cb), the
A signal of 1+"to"8 is output.

Here, when the switch 6 is closed in FIG. 1(a), the display hand changes from the chronograph state to the display hand correction state via the switch control circuit 10. That is, by temporarily turning on the switch 7 (thereby, the signal E is output from the control circuit 10 and the high frequency signal of the frequency dividing circuit 2 is inputted to the motor drive circuit 19 via the drive control circuit 15. Motor A20 for
The hand rotates at the same speed or faster than when the chronograph is normally driven, or by inputting a signal of one step rotation per operation of the switch 7 to the drive circuit 19, the hands as the chronograph display A. Displace by one step,
Alternatively, the position of the display hand can be corrected by driving it at an even higher frequency and displacing it. In this way switch 7
Indicator hand 21 corresponds to switch 8, indicator hand 24° corresponds to switch 9 (corresponding to this, each indicator hand 27 is set independently, and the position of the two hands is adjusted to the 0 position or any arbitrary position of the chronograph. After determining the mechanical 0 position of the needle in this way, the switch 6 is opened (LOW) again in order to match the 0 position of the electronic circuit.At the same time, the switch control circuit 10 sets the D22 position to Hlgh, t. In order to reset the measuring circuit 16 including the time counter 11, all electronic circuits are reset to the 0 state.The chronograph is now in a state where it can be used again.If the switch operation and electronic If the circuit operations are not matched, it will not be possible to clearly separate chronograph measurement and needle position correction using the switch, so if the OG display hand shifts, remove the back cover, take out the movement, and reinstall the hand. Alternatively, it is necessary for general users to completely memorize the operating procedure and use the combination of switches 7, 8, and 9, or to distinguish between OG operation and needle position correction using the so-called time difference, by holding down switch 7 and bringing it to correction mode. It is extremely difficult to understand.

In the method of the present invention, the return from the nail position correction state to the chronograph operable state and the return to the chronograph usable state correspond to the opening of switch 6 (switch B is pushed in in Fig. 2). This is extremely easy to understand, but the method using the above-mentioned time difference for OG recovery to which the present invention is not applied is difficult to understand as an operation.

Here, the present invention will explain how to effectively arrange the operation switch group of the chronograph. In Fig. 2, the CG operations include start/stop switch 7 and switch 8.
is reset, switch 9 is split (or wrap)
When you operate this type of conventional electronic watch, digital watches usually have one start/stop switch 7 and a stop switch 8 that also has a split function. When a digital liquid crystal panel or the like is used, the user can immediately know the operation by displaying the current operation status on the panel, but split operations and the like are usually extremely difficult to understand.

In the present invention, by separating these difficult-to-understand contents into operation switches, normal simple stopwatch operations can be covered by button operations on the right side of the watch, and the complicated functions of the split can be used. It is arranged in a position that can be used by people who want to measure 1st and 2nd place, etc. (people who can use it) understand and use it. Therefore, if you do not need the split function, you can leave switches 7 and 8 as they are and remove the button serving as switch 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. Furthermore, as already detailed in the adjustment of the Oq hand position, the display hand can be adjusted independently according to each button, so there is the operational advantage of being able to adjust the chronograph hand extremely easily. When disassembling and repairing a watch, when installing the OG hand or the rear hand, check for misalignment of the scale and upward and downward movement of the hands.If you turn on the switch while the display hand is corrected, it will respond to the switch operation. Since you can feed the needle with a hand, you can easily perform a G stroke. In addition, by performing this operation, if we consider the hand correction state as a counter state rather than a chronograph timepiece, we can use the switches (buttons) corresponding to the display hands 27 and 21 as detailed in the text. ) By pressing operation 2 and 7, the display hands can be used as one counter for multiple (in this case, two) by independently rotating the display hands by one step each time the buttons are pressed. Therefore analog! By providing a chronograph watch with operation and correction functions as in the present invention,
A chronograph with a counter function can be easily created.

As described above, in the present invention, operation as a chronograph does not have a complicated operation feeling due to the correspondence between the electronic circuit and the function of the operation buttons, and for this reason, even in watches such as analog watches where it is difficult to explain the operation of the buttons, various functions can be complicated. It details an example that can be realized without any detailed explanation, and makes it possible to operate and use an analog chronograph, which was previously impossible.
