Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a configuration of a function operation means in a pointer-type timepiece having a plurality of functions in addition to a time display function.

[0002]

2. Description of the Related Art A pointer-type timepiece has a basic function of displaying a current time or a current date by adding an elapsed time to an initially set time, and a hand setting function for initializing the time. It is. Also preferably, there are a date display function that does not require month-end correction, a time difference correction function that is convenient for travelers, and the like. Further, there may be various additional functions such as an alarm function and a chronograph function. In addition, the correction of the hands used to be that the second hand to the date plate were mechanically restrained by a train of trains, and were forced to rotate by the crown.

Recently, however, an electric switch mechanism is provided on an external operation member such as a crown to detect the position of the drawer stage in the axial direction, the rotation direction, and the rotation speed, and to drive the hands by combining the switch signals. , And independently driven by a separate motor for each pointer, and can be rotated forward and backward as necessary, thereby facilitating control of each function. In addition, various hand-held timepieces having functions other than the above basic functions are also provided.

[0004]

However, this is particularly noticeable in a wristwatch. However, when a small external operation member needs to be pinched and operated by a fingertip, the operation of the pointer control is easy and the risk of erroneous operation is reduced. It has not yet been said that a sufficiently satisfactory configuration has been established in terms of reliability (including clarity of the operation method) and simplification of the mechanism including the number of external operation members related to the number of switches. It is a difficult situation.

For example, in the case of the time difference correction mechanism, in the era of mechanical control, there has been a mechanism in which a clutch mechanism is provided on the hour hand shaft and only the hour hand can be independently rotated, but this configuration increases the thickness of the wristwatch. , Complicating the structure and increasing the manufacturing cost. However, in the so-called electromagnetic operation of the pointer (a method in which the motor that drives the pointer is controlled by a switch linked to an external operation member and the pointer is rotated forward or backward by an arbitrary amount to set the position of the pointer), the operability described above is obtained. It has not yet been proposed a configuration which can achieve a satisfactory level of reliability, simplicity and structure.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a timepiece in which the hands are electromagnetically corrected and which has the operability, certainty, and simple structure of the correction.

In order to achieve the above object, a pointer-type timepiece according to the present invention has the following features. (1) An electronic means for detecting a crown step position and an electric means for detecting rotation of the crown, wherein one of a plurality of functions is selected by the electric means for detecting the crown step position. An electronic means for detecting the operation of an external operation member and a timed circuit means, wherein the hands of the selected one function are operated by electric means for detecting the rotation of the crown at the step position. When the external operation member is operated while the electric means for detecting the step position of the crown is detecting a predetermined step position of the crown, another function different from the plurality of functions is performed during a predetermined period. It is configured to be operable.

[0008] The pointer type timepiece of the present invention may further have at least one of the following features. (2) The external operation member is another external operation member different from the crown, and the predetermined crown step position is zero step.

(3) The other function is a time difference correcting function.

(4) The other external operation member is a push button which is buried in the exterior part of the timepiece and is difficult to be carelessly operated.

(5) It has a notifying means for notifying that the predetermined period is in progress.

(6) The notifying means is means for modulating the state of movement of the second hand.

(7) A notifying means which operates when the external operation member is operated is provided.

(8) The notifying means is means for rotating the second hand at high speed.

(9) When the other external operating member is operated while the electric means for detecting the step position of the crown detects another step position different from the predetermined crown step position, the watch All circuits are reset.

[0016]

FIG. 2 is a plan view showing the appearance of a pointer-type wristwatch and an external operation member according to an embodiment of the present invention. 100 is an exterior member housing the mechanism body of the wristwatch, 101 is a second hand, 102 is a minute hand, 103 is an hour hand, 1
04 is behind the dial and the date number (1
~ 31). Second hand 101, minute hand 10
2. The date plate 104 is independently driven by a dedicated step motor (the internal mechanism is not shown). Hour hand 1
Numeral 03 is connected to the minute hand 102 by a reduction gear train, moves together with the minute hand, and is not driven independently. Only the minute and hour hands can be driven in reverse rotation.

Reference numeral 105 denotes a crown, which is axially zero-step, 1
It has three positions, a step and a step. The spacing of each step is exaggerated. Reference numeral 106 denotes a push button, which is buried in the middle of the thickness of the exterior member 100 in the present embodiment, and cannot be operated unless the tip is pushed toward the center of the watch with a pen tip or the like. This prevents erroneous operations that may be inadvertently performed at normal times. Although not shown below, the step position of the crown 105 is detected by a switch contact that is connected to the internal circuit and opens and closes in conjunction with the axial movement of the crown, and rotation of the crown is detected by a switch contact that opens and closes in conjunction with the rotational movement. Is done. Push button 1
06 also has a switch contact for detecting that the push operation has been performed.

FIG. 1 is a block diagram functionally showing the internal circuit configuration of a pointer-type timepiece shown in FIG. 2, which is an example of an embodiment of the present invention.
(B) is a correction function circuit part. The time signal generation circuit portion includes an oscillation circuit 71 using a crystal oscillator, and various materials used to divide the stable reference signal Q1 into a one-second signal Q2, which is a cycle per second, and generate various control pulses. A frequency dividing circuit 72 for obtaining an intermediate frequency divided output Q3 including a frequency signal group, second / minute / hour / day / month / age counters 74 to 78
Consisting of

Second / minute / hour / day / month / year counter 74-7
Reference numeral 8 also functions as a frequency dividing circuit. The one-second signal Q2 is counted and finally a normal minute hand drive signal Q4 and a normal date plate drive signal Q5 are output. The aging refers to any one of the 0th, 1st, 2nd, and 3rd years from the leap year. In the normal time display state, the step motors for the second hand, the minute hand, and the date plate are driven at timings when the signals Q2, Q4, and Q5 are output.

The configuration and schematic function of the correction function circuit will be described below. The crown position detecting circuit 1 outputs a signal P10 if the crown position is currently at the 0th stage, and a signal P if the crown position is at the 1st stage.
If the signal 11 is in two stages, the signal P12 is output at H level (logical value 1; the same applies hereinafter). Also, when the crown is rotated by a sufficient angle regardless of the step position, a part of the crown touches the two fixed contacts in close proximity in the process, and the crown rotation detection circuit 2 determines the rotation direction in the order of touching. Each time the clockwise signal P21 or counterclockwise signal P22 is output as a single pulse at H level.

If the crown rotation speed is high and the time interval for contacting the two contacts is shorter than a predetermined value, the signal P2
The signal 1 or the signal P22 is changed to a continuous pulse, so that in the case of a large correction, a continuous rotation operation is not required (the continuous pulse is stopped by the second operation). Push button switch circuit 3
When the push button 106 is pressed, the contact operates, and the push operation signal P3 is output as an H-level single pulse.

When the crown is pulled to the second stage, the reference setting / time correction function circuit 4 receives the signal P12 and enters the operation ready state. Further, receives the rotation signal P21 or P22 and receives the rotation signal P43 or P43 of the minute hand. The reverse rotation signal P44 is output, and the minute hand is step-driven in the forward or reverse direction according to the pulse number. When the push button 106 is operated when the crown 105 is at the second position, the signals P12 and P12 are output.
An output signal P41 of the AND circuit 41 having 3 as an input sets the state storage circuit 42, which is a flip-flop, and outputs an all-reset signal P42 that maintains H level.
The all-reset is to simultaneously reset portions of the clock circuit that need to be initialized in operation.

Reference numeral 5 denotes a calendar correction function circuit which is activated when it receives the signal P11 at the first stage position of the crown and receives the clockwise rotation signal P21 at this time.
In the forward direction. This is not to correct the second position, but to read the month and year data, which are not normally displayed, into the clock circuit. That is, when the second hand is pointing at 5 seconds (1 o'clock position), it is 0 years in January, 6 seconds is 1 year in January, ... 10 seconds (2 o'clock position) is 0 years in February, 0 ... 57 seconds. Represents November and 3 years old. A signal P52 generated when the crown is turned counterclockwise at the first stage acts on the drive system of the date plate 104 to advance the date by one day. There is no reversal correction in the calendar correction function.

When the crown 105 is pushed into the zero position after setting the reference position of the hands at the second stage of the crown, the correction state is released, but the hour and minute hands set at the moment when the crown is returned are set to the clock. Read into the circuit. In other words, the pointer position set when the second-stage position is in the all-reset state is stored as a reference position (zero position). When the push button 106 is not pressed and the function is merely a time correction function, the pointer position is corrected. At the current time, the hands start again.

Reference numeral 6 denotes a time difference correction circuit, which normally displays only the time when receiving the signal P10 at the 0th crown position, but operates when there is an operation signal P3 from the push button switch circuit 3. State. During this period, the minute hand (the hour hand 103) is rotated in the forward direction or the reverse direction by one hour while the hand normally moves in accordance with the generation of the crown rotation signal P21 or P22. If the correction of only the desired time difference is completed, the time difference correction state is released in a relatively short time by a timed circuit (details will be described later). This concludes the description of the general operation of the timepiece.

FIG. 3 is a block diagram showing a more detailed circuit configuration of the pointer type timepiece which is an example of the embodiment of the present invention. It should be noted that, in FIG. 1, the way of assigning symbols to each block except for the above-mentioned ones is as follows: 70's are time-related circuits; 60's in frame 6 are time difference correction function-based circuits; Indicates a circuit of the calendar correction function system, reference numeral 40 indicates a circuit of the reference adjustment / time correction function system, and reference numerals 80 and 90 indicate other circuits (however, only the second signal passage control circuit 53 corrects the time difference and the calendar correction). , Time correction). The power supply for all circuits
Button-type batteries commonly used in watches may be used,
It is also very desirable to use a solar cell arranged on the dial and a secondary storage means charged by this as a power source from the necessity of maintenance for battery replacement.

First, in the normal state where the crown is at the 0th stage and the time-related circuit is not reset, the frequency dividing circuit 72
The second-second signal Q2 emitted every second passes through the second-signal passing control circuit 53, passes through the second hand modulation circuit 62 and the OR circuit 81 that do not normally perform a modulation operation, and becomes a signal P81 as a signal P81. Signal P8 with waveform
2 (generated based on the signal Q3), which is input to the second hand drive circuit 83, and the drive output signal P83 causes a second hand step motor (not shown) to advance in the forward direction. The signal P62, which is the signal Q2, is applied to a second counter circuit 74, which is a 60-digit counter, and the circuit counts this signal and outputs 1 per minute.
A normal minute hand drive signal Q4 appearing twice is output.

The signal Q4 passes through the OR circuit 84 and the signal P4
The output signal P8 is applied to a non-inversion waveform generation circuit 85 (having substantially the same configuration and function as the circuit 82).
5 passes through an OR circuit 86 and is applied to a minute hand drive circuit 87, and its drive output signal P87 causes a minute hand drive step motor (not shown) to advance in the forward direction by one minute. The signal P84, which is the signal Q4, has a full count of 1440.
It is applied to the addition input of a minute counter 75 which is a reversible counter of (= 60 minutes × 24 hours) and outputs a normal date driving signal Q5 which appears once every 24 hours.

The signal Q5 passes through the OR circuit 90, and the output signal P90 of the signal Q5 is transmitted to the forward rotation waveform generating circuit 91 (a large torque is required in the case of a date plate, so that the output shaft of the motor is decelerated and the driving pulse The output signal P91 is applied to a date plate drive circuit 92, and the drive output signal P92 is supplied to a date plate drive step motor (not shown) for one-day forward rotation. Step in the direction.
The signal P90, which is the signal Q5, has a full count number of 31.
Is applied to a day counter 76, and its output signal Q6 is applied to a decimal month counter 77 and its output signal Q7
Is applied to a quaternary age counter 78. Month counter 7
7 and the age 0 of the age counter 78.
The signal Q9 is fed back to the day counter 76, and when the last day of the small month is passed, the date plate is fast-forwarded by the number of extra days, and the count value of the day counter 76 is changed to 1 (detailed circuit not shown).

Next, before describing various correction states, the operation of the second signal passage control circuit 53 will be described. This circuit can be realized mainly by a combination of logic gate circuits such as AND and OR. The detailed configuration is omitted because it is out of the central part of the present invention. Its operation is to change the one-second signal Q2 into three states of the crown position, namely signals P12, P11, P
10 as a control input, three destinations, ie, a second counter 7
4. It is determined whether or not each of the OR circuit 81 and the second hand modulation circuit 62 is allowed or blocked from passing.

That is, when the crown is at the second stage position, the one-second signal Q2 does not pass through the second signal passage control circuit 53 at all.
When the crown is at the first stage position, the signal Q2 is allowed to pass to the second counter 74, but is prevented from passing to the second hand modulation circuit 62 and the OR circuit 81. When the crown is at the 0th stage, the signal Q2 is allowed to pass through all of the second hand modulation circuit 62, the second counter 74, and the OR circuit 81.

Now, the reference matching circuit system will be described in detail. When the signal P12 is output at the second crown position and the operation signal P3 of the middle push button is generated, the AND circuit 41 which receives both signals outputs the H-level signal P41 and sets the flip-flop circuit 42. The output signal P42 at the H level acts as an all-reset signal on the R terminals of the time-based second to year counters (74 to 78) to reset them to zero count and maintain the state. The frequency dividing circuit 72 also resets only the last two or three stages in order to make the temporal phase when the second hand is restarted substantially constant.
The signal Q3 from the higher frequency divider continues to be emitted.

When the crown is rotated clockwise or counterclockwise in this state, a signal P21 or P22 is generated, and a two-stage position signal P
The drive waveform (forward or reverse) for normal rotation or reverse rotation is applied to the forward rotation waveform generation circuit 85 or the reverse rotation waveform generation circuit 89 through the AND circuit 43 or 44 opened by 12 and further through the OR circuit 84 or 88. The diversion is a unipolar pulse, and the reverse is a pulse group of bipolarity formed from the signal Q3) and output as a signal P85 or P89, either of which is passed through an OR circuit 86 and a minute hand drive circuit 87.
, The minute hand 102 (and hour hand) is advanced in the forward or reverse direction. Although the signal P84 or P88 is applied to the minute hour counter 75, since it is in the reset state, the zero count is maintained.

Move the hour and minute hands to a predetermined zero position (for example, 12:00
Minute), then return the crown to the first step and move the second hand 10
1 and the initial position of the date plate 104 (for example, the second hand is 0 second, and the date plate is 1 day). After that, when the crown is returned to zero, the initial positions of the hands are stored in the clock. In other words, the signal P10 generated by the crown return operation is output from the flip-flop circuit 42.
Is reset, the signal P42 disappears, the all-reset state is released, and each counter and each pointer resume normal operation in a state where the phase of the count and the pointer position match.

Next, the time correction function circuit system will be described.
The crown is pulled out to the second position, but the push button is not operated, so no all-reset is performed. Further, the signal Q2 does not pass through the second signal passage control circuit 53, the normal hand operation and the time counter stop, and only manual operation is possible. Further, the pulse adding circuit 55 outputs a fast-forward pulse until the second counter 74 becomes zero. Therefore, the second hand 101 stops at the 12 o'clock position. AND circuits 43 and 44 opened by signal P12
Is passed through the crown clockwise signal P21 or the counterclockwise signal P22 and guided to the forward rotation waveform generating circuit 85 or the reverse rotation waveform generating circuit 89, so that the minute hand 102 and the hour hand advance in the forward or reverse direction in the same process as the reference setting. Let it. At this time, the forward rotation signal P84 is applied to the addition terminal A of the minute / hour counter 75 and the reverse rotation signal P88 is applied to the subtraction terminal B to change the count value, so that the phase of the pointer position and the phase of the count is maintained. When the crown is returned to the zero stage after the correction at the desired time, the clock returns to the normal state.

Next, the calendar correction function circuit system will be described. When the crown is pulled out to the first position, a signal P11 is generated, and the AND circuits 51 and 52 are opened. First, when the crown is turned clockwise, the generated signal P21 moves forward through the AND circuit 51, the OR circuit 81, the normal rotation waveform creating circuit 82, and the second hand drive circuit 83 in accordance with the clockwise rotation of the crown. . The user sets the second hand position to match the current age and month based on the rules described in the description of FIG. The manual correction signal P51 advances the month counter 77 in synchronization with the second hand 101.

In order to display the month and the year with the second hand 101, a second hand position counter which always operates in conjunction with the second hand 101 is provided.
It is necessary to switch the second hand position counter and both of the above-mentioned counters in synchronization with the mode so that they match each other. However, the illustration becomes complicated and has no direct relation to the present application, so a detailed description is omitted.

Subsequently, when the crown is turned counterclockwise, the generated signal P22 passes through an AND circuit 52, an OR circuit 90, a normal rotation waveform creating circuit 91, and a date plate driving circuit 92, and a date plate driving step motor (not shown). ) For one day, and
4 moves forward every day. The date plate advance signal P90 is also supplied to the day counter 76 and counts up, so that the phases of the day counter 76 and the date plate 104 match.

After the correction of the calendar (month, age, date) is completed, the crown is returned to the zero position. As a result, the normal hand operation is resumed.

Next, the time difference correcting function circuit system will be described.
When the push button 106 is operated while the crown is at the 0-step position (normal hand movement is being performed), the timer circuit 61, which is a timed circuit, is operated by the signals P10 and P3, and the H level is maintained at the H level for a predetermined period (for example, 30 seconds). The signal P61 is output. The output signal P21 or P22 of the crown rotation detection circuit 2 is applied to the update terminal R of the timer circuit 61 via the OR circuit 67 each time it is generated, and the timed operation is updated and becomes valid for a predetermined time. The signals P10 and P61 open the AND circuits 65 and 66, and activate the second hand modulation circuit 62 (perform modulation operation of the hand movement). There is no signal blocked by the second signal passage control circuit 53, and the 1 second signal Q2 is output by the second hand modulation circuit 62, the OR circuit 81, the second counter 7
4 are supplied.

When the crown 105 is rotated clockwise or counterclockwise, a signal P21 or P22 is generated from the crown rotation detection circuit 2, and one of these signals is used to fast-forward the minute hand by one hour by the 60-minute fast-forward circuit 63 or 64. The output signal P63 or P64 is converted into a number of continuous pulses, one of which is passed through one of the open AND circuits 65 or 66 and one of the OR circuits 84 and 88, or the forward waveform generating circuit 85 or the reverse waveform. Creation circuit 8
9, and is input to the addition or subtraction terminal of the minute / hour counter 75, and drives the minute hand 102 (therefore, the hour hand and the date plate) in the forward or reverse direction in units of one hour without affecting the second hand.

During the time difference correction, the second hand modulation circuit 62 operates in response to the time signal P61, and the movement of sending the second hand twice in a short period of time is performed every two seconds (referred to as a two-second skip hand movement).
(The average hand movement speed for the even number of seconds remains the same as normal.) The current time difference correction function is indicated to be active. If the setting is left as it is after the time difference correction is completed, the set time limit arrives, the timer circuit 60 stops by itself, and the clock returns to the normal state. This is the end of the description of the operation of the clock of FIG. 2 and the circuits of FIGS.

Next, a second embodiment according to the present invention will be described. FIG. 4 is a circuit block diagram of the second embodiment. The same components as those in FIG. This embodiment is characterized in that when the push button switch 106 is pressed to perform the time difference correction, the second hand 101 makes one revolution at a high speed, and the operation informs that the timepiece is in the time difference correction function state.

In the figure, reference numeral 54 denotes an AND circuit, which receives a one-second signal Q2 output from the frequency dividing circuit 2 and a signal P10 at the 0th stage of the crown, and converts the 1 second signal to a second counter only when the crown is at the 0th stage. 74 and the OR circuit 81. 6
Reference numeral 8 denotes a demonstration hand operation circuit which generates a pulse P68 for rotating the second hand at high speed by 60 steps based on the signal Q3 from the frequency dividing circuit 2. The demonstration hand movement circuit 68 receives the signal P10 of the crown 0th position and the signal P3 from the push button switch circuit 3, and outputs a pulse P68 when the push button 106 is pressed to operate the time difference correction function.

Next, the operation of the second embodiment will be described. First, in the normal state where the crown is at the 0th stage and the time-related circuit is not reset, the 1-second signal Q2 generated every second of the frequency dividing circuit 72 is supplied to the AND circuit 54 and the OR circuit 81.
, A signal P82 having a drive waveform for normal rotation (created based on the signal Q3) is input to the second hand drive circuit 83, and the drive output signal P83 is converted to a second hand step. A motor (not shown) is advanced in the forward direction. The signal P81 is 60
Is applied to a second counter circuit 74, which is a decimal counter, and the circuit counts this signal and appears once every minute.
Is output.

The signal Q4 passes through the OR circuit 84 and the signal P
The output signal P8 is applied to a non-inversion waveform generation circuit 85 (having substantially the same configuration and function as the circuit 82).
5 passes through an OR circuit 86 and is applied to a minute hand drive circuit 87, and its drive output signal P87 causes a minute hand drive step motor (not shown) to advance in the forward direction by one minute. The signal P84, which is the signal Q4, has a full count of 1440.
It is applied to the addition input of a minute counter 75 which is a reversible counter of (= 60 minutes × 24 hours) and outputs a normal date driving signal Q5 which appears once every 24 hours.

The signal Q5 passes through the OR circuit 90, and the output signal P90 of the signal Q5 is transmitted to the forward rotation waveform generating circuit 91 (a large torque is required in the case of a date plate, so that the output shaft of the motor is decelerated and the driving pulse per day is reduced). The output signal P91 is applied to a date plate drive circuit 92, and the drive output signal P92 is supplied to a date plate drive step motor (not shown) for one-day forward rotation. Step in the direction.
The signal P90, which is the signal Q5, has a full count number of 31.
Is applied to a day counter 76, and its output signal Q6 is applied to a decimal month counter 77 and its output signal Q7
Is applied to a quaternary age counter 78. Month counter 7
7 and the age 0 of the age counter 78.
The signal Q9 is fed back to the day counter 76, and when the last day of the small month is passed, the date plate is fast-forwarded by the number of extra days, and the count value of the day counter 76 is changed to 1 (detailed circuit not shown).

Next, various correction states will be described. First, the reference matching circuit system will be described in detail. Signal P at 2nd crown position
When the operation signal P3 of the push button 12 is generated during output,
An AND circuit 41 which receives both signals is an H level signal P.
41, and the flip-flop circuit 42 is set. The H-level output signal P42 is used as an all-reset signal as a time-based second to year counter (74 to 7).
8) Act on the R terminals to reset them to zero count and maintain that state. The frequency dividing circuit 72 also resets only the last two or three stages in order to make the temporal phase when the second hand is restarted substantially constant. The signal Q3 from the higher frequency divider continues to be emitted.

When the crown is rotated clockwise or counterclockwise in this state, a signal P21 or P22 is generated, and a two-stage position signal P
The driving waveform (forward or reverse) for normal rotation or reverse rotation is applied to the forward rotation waveform generation circuit 85 or the reverse rotation waveform generation circuit 89 through the AND circuit 43 or 44 opened by 12 and further through the OR circuit 84 or 88. The diversion is of a single polarity, and the reverse is composed of a group of bipolar pulses generated from the signal Q3) and output as a signal P85 or P89, either of which is passed through an OR circuit 86 and a minute hand drive circuit 87.
, The minute hand 102 (and hour hand) is advanced in the forward or reverse direction. Although the signal P84 or P88 is applied to the minute hour counter 75, the minute counter 75 is kept in a reset state, and thus maintains the zero count.

Move the hour and minute hands to the predetermined zero position (for example, 12:00
Minute), then return the crown to the first step and move the second hand 10
1 and the date plate 104 are also in the initial position (for example, the second hand is 0 second,
The date plate is set to 1 day). After that, when the crown is returned to zero, the initial positions of the hands are stored in the clock. In other words, the signal P10 generated by the crown returning operation resets the flip-flop circuit 42, the signal P42 disappears, the all-reset state is released, and each counter and each pointer are in a state where the phase of the count and the pointer position match. Resume normal operation.

Next, the time correction function circuit system will be described.
First, the crown is pulled out to the second position, but the push button is not operated, so that all reset is not performed. The pulse adding circuit 55 receives the signal P12 and enters an operating state to activate the second counter 7.
A fast-forward pulse is output until 4 becomes 0. Therefore, the second hand 101 is fast-forwarded to the 12 o'clock position and stopped. Signal P
The AND circuits 43 and 44 opened by 12 pass the crown clockwise signal P21 or counterclockwise signal P22 and lead them to the normal waveform generating circuit 85 or the reverse waveform generating circuit 89, so that the minute hand 102 and the hour hand are processed in the same process as the reference setting. Moves forward or backward. At this time, the forward rotation signal P84 is applied to the addition terminal A of the minute hour counter 75, and the reverse rotation signal P88 is applied to the subtraction terminal B to change the count value, so that the phase of the pointer position and the count is maintained. When the crown is returned to the zero stage after the correction at the desired time, the clock returns to the normal state.

Next, a calendar correction function circuit system will be described. When the crown is pulled out to the first position, a signal P11 is generated, and the AND circuits 51 and 52 are opened. First, when the crown is turned clockwise, the generated signal P21 passes through an AND circuit 51, an OR circuit 81, a normal rotation waveform creation circuit 82, and a second hand drive circuit 83 to move the second hand 101 forward in accordance with the clockwise rotation of the crown. Let it. The user sets the second hand position to match the current age and month based on the rules described in the description of FIG.
The manual correction signal P51 advances the month counter 77 in synchronization with the second hand 101.

In order to display the month and year with the second hand 101, a second hand position counter is provided which is always interlocked with the second hand 101.
It is necessary to switch the second hand position counter and both of the above-mentioned counters in synchronization with the mode so that they match each other. However, the illustration becomes complicated and has no direct relation to the present application, so a detailed description is omitted.

Subsequently, when the crown is turned counterclockwise, the generated signal P22 passes through an AND circuit 52, an OR circuit 90, a normal rotation waveform creating circuit 91, and a date plate driving circuit 92, and a date plate driving step motor (not shown). ) For one day, and
4 is moved forward every day. Since the date stepping signal P90 is also supplied to the day counter 76 and counts up, the phases of the day counter 76 and the date plate 104 match.

After the correction of the calendar (month, age, date) is completed, the crown is returned to the zero position. As a result, the normal hand operation is resumed. The method of correcting the normal state, hour, minute, and calendar is the same as that described with reference to FIG.

Next, the time difference correction function will be described. When the crown 105 is in the 0-stage position in the normal state, when the push button 106 is operated to correct the time difference, the demonstration hand-operating circuit 68 operates and outputs 60 high-speed pulses P68 to the OR circuit 81. Therefore, the second hand 101 performs high-speed hand movement of one rotation from the operated position. Therefore, the user can recognize that the clock has been shifted to the time difference correction state. During this time, the one-second signal Q2 is continuously output, so that the second hand 101 does not go out of order.

At the same time, the timer circuit 61, which is timed circuit means, is operated by the signals P10 and P3, and outputs the H level signal P61 for a predetermined period (for example, 30 seconds). When the crown 105 is rotated clockwise or counterclockwise, the signal P21 or P2
2 and each one of those signals is a fast forward circuit 60 minutes 63
Or 64 is converted into an output signal P63 or P64 which is the number of continuous pulses for fast-forwarding the minute hand by one hour, one of which is an open AND circuit 65 or 6
6 and either one of the OR circuits 84 and 88 and input to the forward rotation waveform generation circuit 85 or the reverse rotation waveform generation circuit 89, and the addition or subtraction terminal of the minute hour counter 75, without affecting the second hand. Minute hand 102 (hence the hour hand,
Is driven in the forward or reverse direction in hourly units. If the setting is left as it is after the time difference correction is completed, the set time limit arrives, the timer circuit 60 stops by itself, and the clock returns to the normal state.

Although an example of the embodiment of the present invention relating to the time difference correcting function has been described above, the present invention is not limited to this embodiment. For example, on the operation surface, all hands are provided with pointer position counters, which are operated at a high altitude, so that at the time of an all-reset operation, each pointer points to the initial position stored in the clock and stops (the initial position can be confirmed). It is more convenient to use. Further, the external operation member may be of a type different from the crown (for example, a button for operating a contact point by pulling operation, a button that is not buried in the exterior member, or a push button that allows another crown or crown itself to be pushed further than the 0-step position. Or the number of crown steps), and the number is also arbitrary. The function assigned to it (or the like) is also arbitrary. The type and number of functions that can be realized by a plurality of external operation members, the type and number of corresponding pointers, and the type and number of motors that control them are also arbitrary.

The means for informing that other functions are operating, such as during time difference correction, is not limited to the above-described two-second skipping hand movement, but may be another hand movement modulation or another display device such as a liquid crystal display or LED lighting. Although only the example in which the second hand makes one rotation in the demonstration hand operation is given, various changes are possible as long as the time of the second hand does not change, such as five forward rotations and five reverse rotations. The clock circuit that performs the same or similar operation as that of the above-described embodiment is controlled by software such as a program stored in advance, instead of a hardware-like circuit configuration in which many fixed various functional circuits are combined. It can also be realized by controlling the operation of a microcomputer. Such a timepiece is naturally included in the technical scope of the present invention. Various other specifications are also possible.
