Abstract

PURPOSE:To make a corrected position clear and prevent operation from being forgotten by performing the draw-out operation of one of plural external operating members by an electronic circuit so as to place at least plural display needles into the corrected state, and resetting the electronic circuit by the operation into the lock state from the correcting state. CONSTITUTION:A lock switch 6 can correct the '0'-position of a chronograph needle but is locked at the normal time. Switch signals are prevented from chattering by a switch control circuit 9 so as to control a chronograph motor driving circuits 10, 13 jointly with signals from a dividing circuit 2. In this state, since the lock switch 6 is locked in normal chronograph operation, a start-stop switch 7 is pressed to start a chronograph, and a 1/10 second chronograph 12 and an every-second chronograph 15 are rotated. When the switch 7 is pressed again, the chronographs 12, 15 are stopped, and lap time is read as '10 seconds 3,' for instance. The repeated pressing of the switch 7 enables integrated time clocking. The chronographs 12, 15 are returned to '0' by resetting (8).

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a block diagram for realizing a chronograph by separately driving and displaying a chronograph motor, and FIG. 2 shows a display example of a clock in that case.

The signal of the time standard 1 is divided by the frequency dividing circuit 2 to shape the waveform into a signal for driving a motor. The motor driving circuit 3, the time motor 4 and the time display 5 have a well-known basic configuration of analog quartz. In order to display and operate a plurality of chronograph hands, the motor drive circuits 10 and 13, the chronograph motor A11, the chronograph motor B14, and the chronograph hands that display, for example, 1/10 seconds (A).
12. As the chronograph hands, for example, there are two chronograph hands of a chronograph display (B) 15 for displaying every second. The chronograph hand has a start stop switch 7 and a reset (chronograph hand return to 0) switch 8. The lock switch 6 is a switch that can correct the 0 position of the chronograph hand, and is normally locked. The signals of these switches are prevented from chattering by the switch control circuit 9 and combined with the signals from the frequency dividing circuit 2 to control the chronograph motor drive circuits 10 and 13.

In this state, since the lock switch 6 is locked in the normal chronograph operation, when the start / stop switch 7 is pressed, the chronograph is started and the 1/10 second counter 12 and the second counter 15 rotate. To do. When the start / stop switch 7 is pressed again, the chronograph hands 12
And 15 stop, and you can read the lap time, for example, "10 seconds 3". By repeatedly pressing the start / stop button 7, the integrated time can be measured. Next, by turning on the reset switch 8 in the stopped state, the chronograph hands 12 and 15 are reset to zero. (1) The operation up to this point by the switch operation is the same as that of the known mechanical chronograph. However, if the method (1) of returning to 0 is electronically performed, the following problem occurs.

That is, 0 of the chronograph related to the present invention.
Second position alignment will be described. The positions of the chronograph hands 12 and 15 in FIG. 2 operate the electronic circuit described in FIG. 1. Therefore, for example, when a battery is used as a power supply, when considering battery replacement, electrical memory means and other In the case of a normal wrist watch that does not use other power source to back up the battery, the start of the electronic circuit after battery replacement may be (i) arbitrarily started, or (ii) or a circuit for each chronograph hand. It is conceivable to reset all and start from 0. In any case, when the chronograph is started after the batteries are replaced when the chronograph hands 12 and 15 in FIG. 2 are stopped at arbitrary positions, the electronic circuit starts and the chronograph hands start 0. The position will shift.

The present invention treats the chronograph timepiece as circuitally as possible by providing a simple operation means for adjusting the start of the electronic circuit and the position of the mechanical hands, thereby making a complicated chronograph timepiece. It provides one means for realizing the above.

In the electronic circuit of FIG. 3 and the timing chart of FIG. 4, when the chronograph hand is moved to the 0 position or the chronograph hand to an arbitrary position, the electronic circuit is simultaneously reset in the locked state from the corrected state, A correction circuit for starting from 0 is shown as an electronic circuit of a chronograph.

Here, when the chronograph is used in the normal state, a winding stem that interlocks with a well-known needle alignment reference is used as the lock switch 6 of FIG. By doing so, the switches 7 and 8 operate exclusively for the chronograph in the normally pushed position.

At the 6aw position where the winding stem is pulled out, the lock switch is released, and the chronograph hands can be corrected (High b in FIG. 4). Therefore, the lock switch does not operate normally, but only with the winding stem pulled out, so you can use it as a chronograph with confidence.
It is also possible to correct the deviation of the chronograph hands due to falling etc.

In FIG. 3, a motor drive circuit A10 and a motor drive circuit B13 respectively corresponding to the display hand A and the display hand B are composed of a flip-flop 20 (hereinafter referred to as FF) and AND gates 21 and 22. A signal is supplied from the selection means S. The selection means S is supplied with an input g from a switch 8 which is a third external operation member and a display signal generating means D composed of a frequency dividing circuit 2 (FIG. 1), an AND gate 23 and a timer or counter 17. Both the input a and the input a to be supplied are mixed and supplied by the OR gates 18 and 19, and the input g and the input a ′ are based on the selection control input c supplied from the switch 7 which is the second external operation member. The signal is selectively sent to either the drive circuit A10 or the motor drive circuit B13.
Here, similarly to the selecting means S, the display signal generating means D receives the input c as a reset signal.

The operation of the circuit will be described. The input c of the switch 7 is sequentially input to the FF 20 as a clock input, so that the outputs Q and Q of the FF 20 alternately repeat High and Low, and the AND gates 21 and 22 are alternately activated. At this time, since the output Q of the timer 17 becomes High every time the signal c is input, if the timer set value is output only for 6 clock pulses, the output becomes Low and cannot be output. The outputs of the six Q's that are high are input to the gate 23, and the gate 18 and the gate 2 are input.
Since it is input to the chronograph motor drive circuit A10 via 1, the motor rotates 6 steps. Then switch 8
Input the desired number of times and input the signal g.
Similarly, since the motor drive circuit 10 is moved via 8 and 21, the chronograph hand 12 can be moved by an arbitrary amount by inputting to the motor while pressing the switch 8 of FIG. 2 during operation. Operate switch 7 in exactly the same way to input signal c
When inputting, the output Q of FF20 becomes High and the gate 22 becomes High, and at the same time, the timer 17 operates,
The output Q of the timer 17 enters the gate 23 and the gate 1
9, through gate 22, chronograph motor drive circuit B
Enter 13. Then, an arbitrary amount of signal is given from the switch 8 to output a signal to the motor drive circuit 13 by the arbitrary amount.
Therefore, as shown in the operation of FIG. 2 and the movement of the needle (FIG. 4) again, when the switch 7 is pushed, the hands 12 and 15 are sequentially rotated while the timer 17 is High in response to the input of the switch 7,
Specify whether 2 or 15 is modifiable. The amount of rotation of the hands by this timer can be set to one rotation of the chronograph hands, and which hands are corrected by vibrating operations such as plus one step and minus two steps or plus one step. Can be specified. In the latter case, since the correction selection display signal vibrates the display hand before and after its initial position, the displayability is emphasized, and the amount of hand movement having a positive correlation with the displayability is increased. However, at the end of the hand movement by the correction selection display signal, the display hand stops with zero or almost no displacement from its initial position, so the subsequent correction of the display hand position is significant. It will be easier. Although two chronograph hands are shown here, three or more chronograph hands can be used to indicate the chronograph hands by rotating similarly when sequentially selecting. The needle thus selected is corrected to the 0 position, for example, by the switch 8. Then, by pushing in the winding stem as the lock switch 6, the correction state is switched to the chronograph operation. In this state, the start / stop button 7 and the reset switch 8 are operated as a stopwatch, and the function of the reset 8 is the electronic circuit that rapidly feeds the motor input signal from the start and the amount of difference for one rotation of the needle. , It is possible to electronically send the chronograph hands to zero. The explanation of this circuit is omitted because it is not the purpose of the present invention. When started, the electronic circuit and the needle have different 0 start positions, and the electronic circuit only counts the signals delayed to the motor. Therefore, when resetting, the signal for one rotation of the needle and the difference between the count number are used to drive the motor, so that if the 0 position at the mechanical start is shifted, the rapid feed amount will be The misaligned position will stop, and the mechanical zero
It is not possible to realize an accurate chronograph in which the position and the feed amount of the electric signal are synchronized.

The merit of switching from the chronograph operation to the correction state of the 0 position of the chronograph hand by pulling out and pushing in the crown connected to the winding stem is brought into the correction state by pulling out the crown. It can be confirmed by the position 6a of the re-use, and by pushing the fuse from the corrected state to return to the normal chronograph state, the electronic circuit is also reset to 0 at the same time and the state is changed from 0 to the start state. There is a feature that can be confirmed by the position of the crown. If it is not the crown, for example, pressing the button that is also used for chronograph correction chronograph operation makes the chronograph hand corrected to the 0 position, and the next push operation tries to return the chronograph to the normal state again. Then, in the case of a push button, there is no means to confirm whether or not the button was pushed, and it is not known whether it is in the corrected state.Be sure to push the button after correcting the chronograph hand in the corrected state. Although it is necessary to return to the normal state, there is a concern that the user may forget to press the button, and the order cannot be remembered as an operation. In the case of the crown different from the chronograph operation unit as in the present invention, there is an advantage that the correction position is clear, there is no wrinkle in the operation, and it is easy to remember.

As described in detail above, according to the present invention, an analog chronograph timepiece is provided by using a plurality of independent motors in a known analog timepiece that drives a motor by dividing a time standard such as a quartz timepiece. Since it is possible to make the start position of the electronic circuit and the start position of the analog needle coincident with each other by providing one means for configuring and easily correcting the 0 position where the chronograph hand starts by external operation, It became possible to realize an analog chronograph watch without using a complicated heart cam or lever.

Another embodiment of the present invention will be described with reference to FIG. In a known so-called calendar timepiece with analog quartz date and day of the week, the lock switch connected to the winding stem as an external operating member is in a neutral state at the first stage of the crown 6 or at the second stage 6a. 25
In general, the date is set, the rotation of the day of the week is quickly corrected, and at the position of the third stage 6b, the second hand is set and the time is adjusted.

When the chronograph mechanism is adopted in such a timepiece with a calendar, the chronograph hands can be easily modified by applying the present invention.

That is, at the position of the crown 6, the correction of the chronograph hands is locked, and at the drawn-out position of the crown 6a, the chronograph correction position is set at the same time as the calendar correction. The second hand of the crown 6b is set, and the crown 6b comes to the hand aligning position. With such a configuration, the switches 7 and 8 can be normally started / stopped / reset as a chronograph timepiece. Then pull out the crown and 6
The calendar can be corrected at the position a, and at the same time, the chronograph hands can be corrected. Furthermore, the time can be adjusted at the position of the crown 6b. Because of this structure, it can be remembered as the corrected position at the position of the crown 6a,
In 6b, since the hands can be adjusted by rotating the crown, for example, when the chronograph hand 12 is in the hour unit and the hand 15 is in the minute unit, the time position of the chronograph hand 12 is added to the normal time display 5. After calibrating for one hour, the hand 15 is set to the same minute position as the time display 5, and the crown 6 is also pushed in. When the chronograph start button 7 is pressed as the normal carrying position, the chronograph hand 12 , 15 are displayed one hour ahead of the normal time display 5 at all times, so that they can be used as so-called time difference or dual separate timepieces. In the analog electronic meter, while trying to make the chronograph multifunctional, without providing any special correction buttons,
It is possible to perform complicated functions with the minimum of three external work members.

Thus, using the correction method of the present invention,
Not only is it easy to operate, but it is also possible to easily develop it to other functions. Similarly, the second stage position of the crown can be used as the needle correction for setting the timer, and a wide range of applications are possible.

As described above, even if the analog electronic timepiece of the present invention is an analog timepiece having a plurality of display hands such as a multifunctional analog timepiece having a chronograph function, it is driven by each of a plurality of motors. Since a plurality of display hands are provided, it is possible to extremely accurately correct the position of a predetermined display hand of the plurality of display hands and adjust the zero position without affecting the other display hands. Further, the position of the display hand can be corrected and the zero position can be adjusted by an extremely simple operation, and an operation error is unlikely to occur.

[0023]

As described above, according to the present invention, in an electronic timepiece having a mechanism for driving a plurality of display hands by an independent dedicated motor, the display hand positions for independently correcting the pointer positions of the plurality of display hands. The present invention relates to a correction device. In this device, when the first external operating member shifts to the correction mode, the second external operating member allows selection of any one of the motors corresponding to the respective display hands, and the selected motor is initially selected. By temporarily supplying the correction selection display signal to move the hand, the operator can be informed which of the plurality of display hands has been selected. After this,
It is possible to correct the pointer position of the display needle selected by the third external operation member. Here, as a method of notifying the operator of the selection of the display needle, it is customary to provide a separate display means. However, in the present invention, for simplification of the display unit and control of the separate display means. In order to simplify the circuit configuration by eliminating the need for circuits and the like, the selection state is notified only by a single display means using a display needle. That is, when the pointer position is corrected, as a means for notifying the operator of the selection of the pointer position itself, a method of operating the display needle by a correction selection display signal generated at the initial stage of selection so as not to hinder the correction operation. In the end, the selection display and the correction operation are performed before and after. Next, in order to compensate for the low display property due to the single display means, the movement of the display needle by the correction selection display signal (temporal operation state of the pointer position, for example, continuous hand movement by several continuous pulses) , Forward / reverse hand movement, etc.) is adopted as an additional display attribute of the display hand. Therefore, despite the existence of only a single display means, the selective clarification function can be realized in an emphasized manner without hindering the correction function. Furthermore, in addition to keeping the above-mentioned display means single, it is possible to introduce the correction selection display signal in the same path as the correction signal before the selection means, so that the introduction path to the selection circuit is single. As a result, the circuit configuration is greatly simplified.

This is because the electronic timepieces driven by independent motors (the effect of simplifying the mechanism system while enabling independent correction of each display hand) increase as the number of display hands increases. It is effective. Thus, the present invention is
(EN) An electronic timepiece having a very simple structure and capable of accurately correcting a plurality of display hands driven by independent motors.
