Abstract

PURPOSE:To obtain a time correcting system which can be operated easily, by selecting successively and cyclically each state of low speed correction, correction stop, high speed correction and correction stop, by a correction switching operation. CONSTITUTION:When a clock is set to a correcting state by drawing out a stem, a switch S1 is closed, an inhibitor 41 becomes off, and also AND gates 37-40 become off through AND gates 33-36 by FFs 30-32 of a reset state. Subsequently, an input to signal forming circuits 44, 45 is cut off, and a step-motor 47 does not turn. Subsequently, when a switch S2 is set to an on-state once by turning the stem to the left, FFs 25, 32 become a set state through a differentiation circuit 22, the gate 37 becomes on through the gate 33, and the motor 47 rotates forward at a low speed by one second pulse phi from a frequency dividing circuit 18. Subsequently, when the switch S2 or S3 is turned on once again, the motor 47 stops in the same way, and subsequently high speed forward rotation, stop, etc. of the motor 47 are selected successively and cyclically. With respect to reverse rotation of the motor, too, it is executed in the same way, and a time correcting system which can be operated easily is obtained.

Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to formulas. The pointers of pointer-type electronic watches are generally adjusted using a mechanical finger adjustment method. This device allows the rotation of the minute and hour hands to be corrected directly by manual rotation of an external operating member such as a crown via a wheel train such as a wheel train or a small iron wheel.

On the other hand, there is also a so-called electromagnetic correction method in which the hour hand and minute hand are corrected by controlling the driving state of a step motor in accordance with the operation of an external operation switch.

In the former case, the amount of rotation of the crown, which is an external operating member, and the amount of pointer correction are proportional, and it is very simple and easy to operate. It is difficult to reduce costs. Conversely, in the latter case,
The structure is relatively simple and has a small number of parts, making it suitable for thinning and lowering costs, but it has the disadvantage that it tends to be complicated to operate and is difficult to handle. In the latter case, it is also possible to accurately control the amount of pointer correction by driving a step motor with a correction signal, or to store the amount of pointer correction electrically. Adjusting the displayed time in 30 minute or 1 hour increments to advance or lag as you move between zones.) Display switching in so-called dual time display, both analog display and digital display. It can be used to achieve additional mechanisms relatively quickly, such as synchronizing the display parts of a composite display clock with a multi-display clock, and switching the display between the current time display and alarm time display using the hands. .

By the way, as for the specific operation method in the latter case, various methods have already been proposed, and all of them are complicated to operate, and especially those that use a crown as an external operation member, are difficult for the user to operate. Many of them are extremely difficult to use, such as having to force the control of the crown rotation speed. In view of this point, an object of the present invention is to provide an electromagnetic correction method that is easy to operate.

Embodiments of the present invention will be described in detail below based on the drawings. 1 and 2 are diagrams showing a pointer type electronic timepiece according to an embodiment of the present invention, and FIG. 1 is a plan view of a main part showing an external operating member mechanism.

1 is a main plate, 2 is a crown fixed to the winding stem 6, and 4 is a mandarin duck whose tip 4a engages with the groove 6a of the winding stem 6, and whose center of rotation is the bottle 1a planted in the main plate 1. be.

Reference numeral 5 denotes a copper foil pattern provided on a circuit board (not shown), which together with the switch spring portion 4b of the mandarin duck 4 constitutes a switch S that is linked to the axial position of the leash 2.

6 is a switch wheel that is inserted into the corner 6b of the winding stem 6 and has a square hole so that the rotation of the winding stem 6 is transmitted;
The four teeth are a contact spring whose base is fixed to the circuit board7.
It's like playing by pressing 9. The protrusions 7a and 9a respectively provided on the contact spring 7.9 are configured to come into contact with the copper foil pattern 8.10 of the circuit board when pressed, and each operates in conjunction with the 20 rotations of the crown.
This constitutes switches S2 and S3. Su・,-zu 2
When pulled out one step, the mandarin duck 4 rotates in the special training direction, and the switch spring 4b contacts the pattern 5, causing the switch S1
is turned on, and the pointer is adjusted. Note that the switch wheel 6 is in the same position whether the IJ and -2 are in the normal position or in the stepped position, but since the corner part 6b is long, the rotation of the crown 2 is different from either of the above. The signal is transmitted to the switch wheel 6 even in the position. When the lead 2 is rotated toward you (counterclockwise direction), the contact spring 7 comes into contact with the pattern 8 intermittently, so that the switch S2 is intermittently turned on, and when it is rotated in the opposite direction (clockwise direction). In the same way, switch S is intermittently on! Useful.

Next, FIG. 2 is a block diagram showing the electronic circuit in this embodiment. Note that the circuit in FIG. 2 operates in positive logic, and in the following explanation, when it is simply written as II or 1, it is logically at II level or 1.
, level. In FIG. 2, 17 and 18 are a well-known crystal oscillation circuit and a frequency dividing circuit, respectively, and the frequency dividing circuit 18 outputs a signal 96o of 1/2011z as a frequency signal for normal driving.
In addition, a signal 961 of 1112 for low-speed correction and a signal 961 of 6411z for high-speed correction are output. Furthermore, 44 and 45 are a signal forming circuit for driving the motor in the normal rotation direction and a signal forming circuit for driving the motor in the reverse direction, respectively.

46 is a motor drive circuit, and 47 is a step motor.

The driving signal forming circuits 44 and 45 each form a signal for driving the step motor 47 in the forward or reverse direction by one step each time one pulse signal is input, The signal is configured to be supplied to the motor drive circuit 46.

That is, the motor 47 is connected to the signal forming circuit 44 or 45.
The pointer device 49 is configured to be driven in the forward or reverse direction depending on the number of pulses input to the motor 47, and the pointer device 49 is driven by the motor 47 via a well-known wheel train mechanism 48. ing.

Next, the operation of the circuit of this embodiment will be specifically explained.

First, when the above-mentioned pins 2 are normally between I and N', the switch s1 is in the OJ''I state, so the inhibitor 41 is in the ON state and the output side of the inverter 21 is in the 11 state. As a result, a Go-type flip-flop circuit (hereinafter abbreviated as -1:1・l・゛)
25 is held in a seven throat state. Therefore, in this state, the output sides of the 8N+) circuits 63 to 36 are all 1, so the AND circuits 67 to 40 are all in the 01"I" state.

That is, in this state, the output signal from the frequency dividing circuit 18. ,S, ,S2] / 20 fiz signal door. The motor 461 rotates forward in one step at 20-second intervals in order to be inputted to the forward rotation driving signal forming circuit 44 through the inhibitor 41 and the OIt circuit 42.
(hereinafter referred to as normal driving state).

In the above state, the A N I) circuit 19.2
0 is maintained in the OFF state (・in order to keep the crown 2
Even if you turn the switch S2 or switch S8 to ON, do not perform any operation that changes the state of the circuit.
It is clear that there is no such thing.

Also, in the above state, since the output sides of the Oit circuits 28 and 29 are at 14 degrees, the i'' type F l=' 30.
61 is held in a reset state.

Next, pull out the crown 2 to set it to the correction state, and the switch S will be in the ON state, and the inhibitor 41 will be OFF.
At the same time, the AND circuits 19 and 20 are turned on, and the output side of the inverter 21 becomes L. However, in this state, since the FI circuits 25, 60, and 61 are still in the reset state, the AND circuits 26, 27 are in the ON state, and the output sides of the AND circuits 66 to 36 are all I7.
Therefore, the A N I) circuits 67 to 40 are all in the 01"F state. Therefore, in this state, none of the signals are input to the signal forming circuits 44 and 45 (
(hereinafter referred to as the corrected standstill state).

Now, from the above state, if the switch S2 is turned ON once by rotating the crown 2 counterclockwise (hereinafter referred to as switching operation), then The n-th pulse signal generated by 22 is transmitted to the ``I'' terminal of the ``I'' type F F3 Q and 11. S type 1” I” 32 ce.

input to the terminal, i, type 1"l"
3 Q is inverted to the heptad state, and it is also ltS type 1・′
F62 is also set. Note that the above pulse signal is O
It is clear that if the reset terminal of the type F I 3 i is manually applied via the circuit 29, the 1 I' 31 will only maintain the seven-node state. .

Furthermore, the above pulse signal is 01 (via the circuit 24,
In order to manually power the ``1'' terminal of the ``1'' type 1-'l'' 25, - in synchronization with the falling edge of the above pulse signal,
1.F25 is inverted to the set state, and the A N D circuits 26 and 27 are in the OF+pa state.

Also, as a result of the above, A N +,) 6 out of circuits 66 to 66
Only the output A law of 6 becomes 11, and therefore only 67 of the A N I) circuits 67 to 4 [1 becomes the QN SE state.

That is, in this state, only the A N IJ circuit 7 and the lIZ signal 2. (via the circuit 42) are manually input to the stop rotation drive signal forming circuit 44.
As a result, the motor 47 enters a normal rotation low speed correction state in which the motor 47 is driven to rotate one stave knob in the normal direction at one second intervals.

Next, from the above state, rotate the crown counterclockwise or clockwise, and set switch S2 or S3 to 1.
When the switching operation is performed, the differential circuit 22 or 2
One pulse signal is formed at 6 and n, but at that time the AND circuits 26 and 27 are still in the OFF state, so the pulse signal cannot pass through the A N D circuit 26 or 27, and the 1 ” No change is caused in the state of F3 Q, 61.62.However, the above pulse signal is OR
In order to input the data to the F I"250'I" terminal via the circuit 24, the F
F25 is again inverted to the reset state, A N I) circuits 26 and 27 are turned on, and AND circuit 6 is turned on.
The output sides of 6 to 66 are all L, and the AND circuits 67 to 4
0 is all in the OI"F state. Therefore, in this state, no iz signal is input to the signal forming circuits 44 and 45, so the timepiece 1 again enters the correction stop state.

In other words, the watch 1 of this embodiment is configured such that even if the switches S2 and 83 are switched once from the low speed correction state in the stopped rotation direction, the correction body is stopped. .

Next, from this corrected body stop state, if the lens 2 is rotated to the left and the switch S2 is operated once more, one pulse signal formed by the differentiating circuit 22 is turned ON. A N I) which is in the state I” through the circuit 26
I" 3 In order to be input to the '1' end A of Q, the I
The output F60 is inverted to the reset state.

Note that the above pulse signal is input to the set terminal of l.
It is also input to the reset terminal of
2 and 61 only maintain the set state and reset state, respectively.

In addition, the L pulse signal is passed through the 0+1 circuit 24 to I.'
Since it is also input to the 250゛I゛ terminal, l.1.25 is inverted to the set state in synchronization with the fall of the above pulse signal, and the It
FI” state is reached.

As a result of the above, only the output of 64 out of the outputs of the AND circuits 66 to 66 becomes I-1.
Since only 68 out of 40 are in the ON state, only the signal 6411z among the output signals of the frequency dividing circuit 18 is
The motor 47 is manually inputted to the forward rotation driving signal forming circuit 44 via the ANI) circuit 68 and the OR circuit 42, and the motor 47 is driven to rotate in the forward direction at a frequency of 6411z, and enters a forward rotation direction high speed correction state.

Furthermore, from the above normal rotation direction high speed correction state, the crown 2
When the switch is rotated counterclockwise or clockwise and the switch S2 or S3 is operated once,
One pulse signal is formed by the differentiating circuit 22 or 26, but at this point the AND circuits 26 and 27 are
Since it is in the F l” state, the above pulse signal is OIt
It is inputted only to the 'I' terminal of the F F 25 via the circuit 24. As a result, since the FF 25 is inverted to the reset state, the A, N I) circuits 26 and 27 are turned on, and the outputs of the A, N I) circuits 63 to 66 are all I, As a result, the AND circuits 67 to 40 are all turned off, and the correction is stopped again.

That is, in the timepiece of this embodiment, even when it is desired to change from the normal rotation direction high-speed correction state to the correction stop state, it is sufficient to switch either one of the switches S2 and 83 once. In addition, in this case, in the corrected state, all of F I"25, 60, and 61 are in the seven-throat state, so it is the same as when the crown 2 is first pulled out and the switch S1 is turned on. The situation has returned to normal.

On the other hand, when the correction body is stopped for the first time by pulling out the crown 2 and turning on the S 1 notch S, or after performing low speed correction or high speed correction in the forward direction, - When switching to state 11,
For 'L' as well, F25 and 61 are both in the reset state. In this state, the
When the switch 2 is rotated clockwise and the switch S is operated once, the 1 formed by the differentiating circuit 26 is
pulse signals are sent to the FF3 via the 8N l) circuit 27.
1 and the reset terminal of the FF 32, the FF 31 is inverted to the set state and the FF 32 becomes the reset state.The above pulse signal is input to the OR circuit 28. via I-'F 3
Since fL is also input to the reset terminal of Q, the F F
3 [1 becomes a seven throat state.

Further, the above pulse signal is passed through the OR circuit 24 to the FF2.
Since it is also input to the ``I'' terminal of 5, FI'' 25 is inverted to the 7-node state in synchronization with the fall of the pulse signal mentioned above, and the AND circuits 26 and 27 are in the OFF state. becomes.

As a result of the above, only the output side of 35 of the A N I) circuits 63 to 66 becomes I-1, and the A N I) circuits 67 to 66 become I-1.
Since only 69 out of 40 are in the ON state, only 5 of the output signals from the frequency dividing circuit 18, 1]IZ signal DA, is sent to the reverse drive circuit via the A N D circuit 69 and the Or1 circuit 46. 45, the motor 47
is driven in a direction opposite to the normal driving direction at a frequency of 111z, resulting in a reverse direction low speed correction state. Furthermore, it is clear that if either switch S2 or S3 is operated once from this state, F l'' 25 will be reversed to the reset state, and will again return to the correction stop state.

It is also clear that at this time, there is no change in each state of I, 30, 61, and 62 at all.

Furthermore, when the switch 7 and the switch S3 are operated once from the above-mentioned state where the correction body is stopped, the differential circuit 26 forms a pulse signal of 1.
is in the reset state, and 1, 1, and 25 are in the set state, so that the output of A N I) circuit 66 becomes A N +) circuit 40.
Since the ladle is in the ON state, the signal 6411Z is input to the signal formation circuit 1'345 for reverse rotation and driving, and the time opening is in the state of high-speed correction in the reverse direction. .

Also, from this reverse direction high speed correction 11: state, it is clear that the state can be switched to the time and night correction body 1F state with a single switching operation of either switch S2 or S, and as a result, l・'F 25.60, all of the filters 1 and tL are in the reset state, and the crown 2 is first pressed.
The state is the same as when the switch is pulled out and the switch S1 is turned on.

Furthermore, from this state, it is clear that if the switch S2 or S3 is operated again, the normal rotation direction low speed correction state or the reverse rotation direction low speed correction state will be established.

In addition, in the reverse direction low speed correction state, switch S2 or S
When 3 is brought into the correction standstill state by moving the switch once, FF25 is in the reset state, FF"3Q is in the reset device, FF31 is in the set state, and I."F32 is in the set state. It is in the reset state, but when switch S2 is operated once from this correction standstill state, F F 25 is in the reset state,
I'' F61 is in the set state, 1.F61 is in the reset state, and FF32 is in the set state, which are each reversed to enter the normal rotation direction low speed correction state.

That is, in the watch of this embodiment, after switching from a low speed correction state in the forward or reverse direction to a rest state, a switch is provided for making a correction in the opposite direction to the low speed correction direction before the rest state. Even when the switching operation is performed once, the high-speed correction state in the opposite direction does not occur, but the low-speed correction state in the opposite direction is first achieved.

In addition, each of the above correction states or correction standstill state tL
Even from the state of 1., if the lead 2 is pushed back to the normal position and the switch S1 is set to the "Ol" state, the inhibitor 41 is turned on and the AAND circuit 19.20 is set to the 0/F state. Since the output signal of the inverter 21 becomes 1-1, I"I" 25.30.61
are all reset, and as a result, the AND circuit 66
The output side of ~66 is all I, and ΔN +) circuit 6
Since clocks 7 to 40 are all in the OF I” state, clock 1
will return to normal driving state.

That is, in this state, no signal is sent to the normal rotation driving signal forming circuit 44. It is clear that the switching operation of the switches S2 and S3 will not cause any operation.

As mentioned above, in the present invention, IJ and -z are used as the first
The first switch performs a switching operation when rotated in the direction of
When the forward rotation direction low speed correction state, correction body stop state, normal rotation direction high speed correction state, and correction body stop state are cyclically selected in the above order using the switch, and when the crown is rotated in the second direction, The second switch that performs the switching operation allows the reverse direction low speed correction state, the correction body stop state,
Since the reverse direction high-speed correction state and the correction body stop state are cyclically and selectively configured in the above order, it becomes possible to appropriately and easily select the desired correction form without making any erroneous operations. Guidelines can be revised quickly.

In other words, according to the present invention, the correction of the chair in the forward direction or the reverse direction, +1 correction always starts from a low speed correction,
Moreover, because the system is configured to temporarily stop the correction before switching to high-speed correction, it is possible to accidentally switch to high-speed (1% correction) state when trying to stop the low-speed correction. Even if the risk of doing so is eliminated, and even if the amount of correction in either direction is slightly exceeded, correction in the opposite direction will always start from a low-speed correction state. It is also possible to correctly restore the excess amount of repair material very easily and quickly.

In the above-mentioned embodiment, even if the first direction is in the low-speed correction state or high-speed correction state, the operation for switching from the correction state to the correction stop state is performed by pressing the crown on the left or right side, +L. So that you can rotate in the direction (
However, with this configuration, when the pointer reaches the desired position, the doubling operation can be stopped very quickly. However, unlike the above configuration, in the modification state, the switching operation of the switch for performing a modification in the direction opposite to the direction of the modification being executed is insensitive. It is also possible to configure L=J so that the state cannot be changed to the state in which the correction is stopped except by the switching operation of the switch corresponding to the direction of the correction being executed.
