Abstract

PURPOSE:To realize an additional function while maintaining a simple design of a watch, by linking an instruction given by the operation an outside operation member to the operations of the watch and the hand thereof. CONSTITUTION:When a crown 2 is pulled to be set at a position 2', a setting lever 4 is rotated clockwise, a switch spring member 4b is thereby made to contact with a pattern 5, and S3 is turned ON. At this time, the rotation of the crown 2 is transmitted to a switch wheel 7 at its ordinary position. When the crown 2 is rotated to this side, a spring 8 contacts with a pattern 9 intermittently, S1 is turned ON intermittently, and by rotating the crown 2 in the opposite direction, S2 is turned ON intermittently. When the crown 2 is further pulled out to be set at a position 2'', the spring member 4b contacts with a pattern 6 and S4 is turned ON. As to a button 12, a contact 13a contacts with a pattern 14 to turn S5 ON when it is at a position 2'.

Description

[Detailed description of the invention] Regarding a pointer display type additional function watch that is used to display both the current time and a second time such as an alarm time, more specifically, the pointer is switched in conjunction with the operation of an external operating member. The present invention relates to a display switching device for displaying images.

An object of the present invention is to provide a timepiece in which the same hand selectively displays either a first time or a second time.
By allowing the user to directly command whether to display the first time or the second time when switching to another display, the responsiveness of the pointer's operation to that operation can be further improved. This makes it easier for the user to understand the display switching operation.

The next object of the present invention is to provide a structure in which, even if the display switching operation is performed again while the watch is in the display switching operation, the clock and hands will immediately and reliably operate according to the user's instructions. This makes it easier for the user to understand the effects of display switching operations.

Hereinafter, the present invention will be described in detail based on the drawings.

FIG. 1 is a plan view of an embodiment showing an external operation mechanism section of an alarm wristwatch according to the present invention.

1 is the main plate, 2 is the leash that fits into the winding stem 6, and 4 is the winding stem 6.
This is a mandarin duck whose tip 4a fits into the groove 3a of the mandarin duck, and whose center of rotation is the bottle 1a planted on the base plate 1. A pin 4C is implanted in the mandarin duck 4 and is pressed by a back pusher 15. The crown 2 can therefore be selectively and stably set in three axial positions: first, second and third.

Reference numerals 5 and 6 are switch contact patterns made of copper foil provided on the circuit board, and are configured to be connected to the switch spring portion 4b of the mandarin duck 4, and are provided as an indicator switch. The S3 and S4 switches are each configured as follows.

7 is a switch wheel provided with a square hole so that the corner 6b of the winding stem 3 can be loosely engaged and rotation can be transmitted, and the four teeth are connected to a contact spring 8 whose base is fixed to the circuit board. It is designed to be played by pressing .10. The protrusions 8a and 10a provided on each of the contact springs 8.10 are configured so that, when pressed, they come into contact with the switch contact pattern 9.11 made of copper foil on the circuit board, thereby providing a correction switch. The S, , S, and S switches are configured respectively.

Reference numeral 12 denotes a so-called push-pull button, which, although not shown, has a positioning mechanism that has two stable positions: a normal position and a position pulled out from FIG.

16 is a switch spring whose base is fixed to the circuit board;
The contact 13a constitutes a switch S that comes into contact with a contact pattern 14 made of copper foil on the circuit board when the button 12 is in the first pull position.

When the lewd 2 is pulled out one step to the second position, the mandarin duck 4 rotates clockwise, the switch spring portion 4b comes into contact with the pattern 5, and the S3 switch is turned on. At this time,
The switch wheel 7 is in the same position as normal, but since the corner 6b is long, 20 rotations of the crown are transmitted, and when the crown 2 is rotated toward you, the contact spring 8 is intermittently changed to the pattern 9. Contact S, turn on the switch intermittently, rotate it in the opposite direction, and do the same with S2.
Turn the switch on intermittently. When the rieuse is pulled out two steps to the third position, the mandarin duck 4 rotates further, and the switch spring portion 4b contacts the pattern 6, causing the S
4 switch is turned on. Switch wheel 7 remains in the same position as in normal times, and IJ.

The rotation of Uzu 2 has the same effect as when pulling the 1st step.

When the button 12 is in the first pull position, the contact 13a contacts the pattern 14, turning the switch on.

FIG. 2 is a plan view of a wristwatch showing another embodiment of the present invention having an operating section structure different from that in FIG. 1.

Five buttons 18a to 18e are provided at the bottom of the watch. Switch springs 17a to 176 are provided correspondingly. 18a and 18b
These have the same functions as the correction switches S H and S 2 explained in FIG. 1, and are similarly written as S8 and S. 18C and 18d have the same functions as the display switches S4 and S explained in FIG. 1, and are similarly written as Sl and S. The buttons 18C and 18d are structured so that they remain pressed in once pressed. 18e is b in Figure 1.
s, S4 switch is in the open state, that is, the crown 2 is in the normal position. When this button 18e is pressed, the buttons 18C and 18d are moved to their original positions, and the S3, It is designed to open S4. The push-pull button 18f corresponds to the switch spring 17.
f is provided and has the same function as S explained and explained in FIG. 1, and is similarly written as S. 16 is a guideline.

Crown 2, winding stem 3, mandarin duck 4, switch S in Figure 1
3.84 etc. and the button 18C118 in Fig. 2
d, 18e, switch springs 17C, 117d, 18e, etc. constitute a display switching command mechanism.

FIG. 3 is a block diagram showing the basic signal flow of the alarm wristwatch shown in FIGS. 1 and 2.

The output of the clock circuit 21 is input to the drive circuit 101 and the interval counting circuit 105. The output signal of the drive circuit 101 is
The torque is input to a motor 28, and the torque output of the motor 28 is transmitted to a wheel train indicator device 29. In normal hand operation, each of the circuits and devices described above operates.

That is, the drive signal output of the drive circuit 101, which is formed in response to the 20 second cycle signal output of the clock circuit 21, is applied to the motor 2.
The motor 28 rotates one pitch every 20 seconds. Its rotation is decelerated by the gear train, and the pointer moves forward (clockwise).

Also, the 92o second periodic signal input to the line 105 changes the count value of the counting circuit therein. The interval counting circuit 105 monitors the interval between the un-4 time and the normal time, and outputs a coincidence signal to the buzzer device 78 when the upper and lower ends match. The buzzer device 78 consists of a sounding body, a driving circuit for making the sounding body, and the like.

The modified switch 102 consisting of the S, , and S2 switches shown in FIGS. 1 and 2 is connected to the switch input control circuit 10j.
l is connected. The output of the control circuit 104 is the drive circuit 101, the interval counting circuit 105 and the interval storage circuit 66.
has been entered.

The display switch 103 consisting of the S3 and S4 switches shown in FIGS. 1 and 2 has a switch input control circuit 104,
It is connected to the second time display movement control circuit 66 and the first time return control circuit 64. Second time display movement control circuit 6
6 and the first time return control circuit 64 are both input with a fast forward signal from the fast forward signal output circuit 40, and further have a drive circuit 101, an interval counting circuit 105, and an interval storage circuit 6.
Output to 6. The fast forward signal output circuit 40, the second time display movement control circuit 66, and the first time return control circuit 64 constitute a motor output circuit 106.

The second time display movement control circuit 66 receives control signals from the interval counting circuit 105, and the first time return control circuit 64 receives control signals from the interval storage circuit 66.

If you put Leeuzu 2 in the second position (P in Fig. 1), or press button 18d on the button-type watch in Fig. 2, press S3.
When the switch is turned on, the fast-forward signal from the fast-forward signal output circuit 40 is output from the second time display movement control circuit 66. This fast-forward signal activates the drive circuit 101 to output a fast-forward drive signal to the motor 28. Therefore,
The pointer moves rapidly in the positive direction. Periodically with this operation, the fast-forward signal is applied to the first and second pulses of the interval counting circuit 105.
The count value between times is decreased, and the count value of the interval storage circuit 66 is increased. After a while, when the count value between the first and second times of the interval counting circuit 105 becomes 0, the
It acts on the time display movement control circuit 66 to stop outputting the fast forward signal. Therefore, the first
The time difference between the two times has been moved to the interval storage circuit 66.The pointer stops with the second time, which is the alarm time, indicated.This state is the alarm time monitoring state.

In this state, when the sl or S2 switch, which is the correction switch 102, is operated, the alarm time is corrected.

When the S or S2 switch is intermittently turned on or off, the switch input control circuit 104 outputs a corresponding correction pulse.

This output and force actuates the drive circuit 101 to output a drive signal to the motor 28, causing the pointer to rotate forward or backward.

This correction pulse is also input to the interval memory circuit 66 at the same time to increase or decrease the count value, thereby maintaining synchronization with the pointer.

Next, return crown 2 to the first position and press button 18e.
When the S3 switch is turned off by pressing , a fast-forward signal from the fast-forward signal output circuit 4o is output from the first time return control circuit 64.

This fast-forward signal causes the drive circuit 101 to operate, but unlike when the switch 83 is turned on, the motor 2
Outputs a reverse rotation drive signal that rotates 8 in the reverse direction. Therefore,
The pointer moves rapidly in the opposite direction.

In synchronization with this operation, this rapid forwarding signal decreases the count value of the interval storage circuit 66 and increases the count value between the first and second times of the interval counting circuit 105. When the count value of the interval memory circuit 66 becomes 0, it acts on the first time return control circuit 64 to stop outputting the fast forward signal. The time difference is returned to the interval counting circuit 105.The hands also return to the state indicating the normal time, which is the first time, and are in the normal hand movement state where the motor 28 is operated by the 20 second periodic signal from the clock circuit 21. Return to

If you put the watch 2 in the third position (Fig. 1 2') or press the button 18C to turn on the S switch, then switch the correction switch 102, SL or S2, to normally adjust the time. will be done.

That is, according to the switching of the S1 or S2 switch, the corrected pulse signal from the switch input control circuit 104 is input to the drive circuit 101, and the output of the drive circuit 101 drives the main motor 28. The pointer is rotated forward or backward.

Moreover, this correction pulse simultaneously increases or decreases the count value of the interval counting circuit 105, and acts to maintain synchronization with the pointer.

Further, in the present invention, the switch (83
, 84) directly acts on the second time display movement control circuit 66 and the first time return control circuit 64, so that they immediately respond to the operation of the display switch 106, even if the clock is Even if the watch is moving to the second time or returning to the first time, if the operation is performed in the middle, the watch immediately starts operating according to the operation.

The signal is input to an alarm time sound drive circuit 75 which forms a signal for a chime sound to be sounded. A warning sound drive circuit 76 that forms a signal for emitting a simple single tone is connected to an alarm time sound drive circuit 75, and the output of an OR circuit 77 is input to a buzzer device 78.

The drive circuit 101 in FIG. 3 is composed of the forward rotation and reverse rotation drive circuits 25, 26, etc. in FIG. 4, and the switch input control circuit 104 in FIG.
4, 61, 62, etc., the spacing number circuit 105 in FIG. 3 is comprised of a time integration circuit 68, an alarm time storage circuit 72, a coincidence circuit 76, etc. in FIG.

Next, the operation of the above configuration will be explained.

In a normal state, a signal with a period of 20 seconds from the clock circuit 21 is outputted from the inhibitor 81 of the switching circuit 22, passes through the OR circuit 23, the forward rotation drive circuit 25, and the output circuit 27, and drives the motor 28 every 20 seconds. Move the needle one pinch forward to rotate the gear train and move the pointer.

On the other hand, the signal outputted from the switching circuit 22 passes through the OR circuit 67 and adds up (counts up) the count contents of the time integration circuit 68. Eventually, when the content of the alarm time storage circuit 72 matches, an I level match signal is output from the match signal 76, and if the S5 switch is on,
(1 When the button 12 is pulled out one step in Figure 1,
(or when the button 18f is pulled out in FIG.
7, the signal is input to the buzzer device 78, and the sound is emitted.

Alarm time monitor temporary (when the Ss switch is turned on, that is, in Fig. 1, the second

This signal passes through the OR circuit 54 to the timer counting circuit 52.
and interval storage circuit 66 are reset, and their outputs Q become L level.

The timer counting circuit 52 remains at the L level for one minute, during which time the output of the inverter 56 remains at the H level. The AND circuit 46 of the fast-forward signal output circuit 40 outputs 64Hz.
signal is output, and the forward alarm time monitor control circuit 6
6, the fast-forward signal passes through the OR circuit 69, increases the count in the interval memory circuit 66, decreases the count in the alarm time memory circuit 72, and then passes through the OR circuit 26 and outputs a fast-frequency signal from the forward rotation drive circuit 25. A drive signal is output to rotate the motor 28 and the pointer in the forward direction at high speed.

The H level signals from inverter 56 and switch 83 are
Since the output of the AND circuit 35 is set to H level, the switching circuit 22 outputs a 20 second periodic signal from the AND circuit 82. Therefore, the normal movement of the hands is stopped, and the number of times of the signal is subtracted from the count value of the interval storage circuit 66.

The count value of the alarm time storage circuit 72 gradually decreases, and when it matches the count value of the time integration circuit 68, the matching circuit 76 outputs an H level signal. One of these signals sets the forward alarm time monitor control circuit 66 and prevents the fast forward signal from the fast forward signal output circuit 40 from being further input to the forward rotation drive circuit 25, the alarm time storage circuit 72, and the interval storage circuit 66. prohibit. The other matching signal is inputted to the alarm time sound drive circuit 75 via the AND circuit 74 if the S switch is on, so that the user can be informed by an alarm sound that the pointer has arrived at the alarm time. . You can also change the sound when a match occurs to an alarm sound by creating a new match sound drive circuit that outputs a signal different from the alarm time sound drive circuit 75□11, applying the match signal to this, and changing the output from the sub circuit. It will be possible if it is improved so that it can be input to 77. Note that the pointer indicates the alarm time and stops, and this state is the alarm time monitoring state.

If the crown 2 is rotated in this state, the alarm time will be corrected. S to correct the positive side (forward rotation),
When the switch is switched, the input signal waveform shaping circuit 31 outputs a correction pulse proportional to the number of switching times, and after passing through the AND circuit 33, the switch Ss is turned on, and the output of the timer circuit 50 is (The AND circuit 66 passes the pulse until the H level signal is output.) One side goes through the OR circuit 54 to reset the timer counting circuit 52 and start the timer from the beginning, and the other side goes through the OR circuit 26. Then, the forward rotation drive circuit 25 is activated for each correction pulse to output a drive signal, causing the motor 28 to rotate forward, and further passing through an OR circuit 69 to increase the count value of the interval storage circuit 66.

That is, while the hand representing the alarm time is rotated and corrected in the clockwise direction, an increase in the difference between the alarm time and the normal time corresponding to the amount of correction is accumulated in the interval storage circuit 66.

Now, when the S switch is switched to correct the reverse side (reverse rotation), a correction pulse proportional to the switching is output from the input signal waveform shaping circuit 62 as in the case of correcting the positive side, and passes through the AND circuit 64. After that, one side passes through the OR circuit 54 to reset the timer counting circuit 52, and the other passes through the OR circuit 24 and operates the reverse rotation drive circuit 26 for each corrected pulse to output a reverse rotation drive signal, and the motor 28 is reversely rotated, and further passes through the OR circuit 65 to decrease the count value of the interval storage circuit 66. That is, while the hand is rotated and corrected in the counterclockwise direction, a decrease in the difference between the alarm time and the normal time corresponding to the amount of correction is subtracted from the interval storage circuit 66.

Next, push crown 2 back to its original position as shown in Figure 1, or
When the button 18e in the figure is pressed to turn the switch OFF, the outputs of the AND circuits 53 and 34 are held at the L level, cutting off the inputs to the correction switches So and S2, and the output of the AND circuit 65 is also at the L level. The output state of the switching circuit 22 is returned to the normal hand movement state. Furthermore, the OR circuit 41 of the fast-forward signal output circuit 40 is inverted to H level, and the AND circuit 42 outputs a 64Hz pulse fast-forward signal. 65.24 and the alarm time storage circuit 72. As a result, a reverse rotation drive signal is output from the reverse rotation drive circuit 26 in synchronization with the fast forward signal, and the motor 28 is reversed to rapidly rotate the pointer counterclockwise. The counted value of the difference between the normal time and the alarm time stored in the storage circuit 66 is transferred.

When the hand is positioned at the normal time, the output Q of the interval memory circuit 66
) The signal is reversed to the normal level, and the return alarm time monitor control circuit 64 is turned on, thereby prohibiting the output of the 64Hz fast-forward signal. The hands stop fast forwarding and reversing at the normal time position, and then move normally.

To paraphrase the above explanation according to the clock usage, the first
In the case of the crown-type watch shown in the figure, when crown 2 is pulled out to the second position (pushed to the first click) (or when button 18d is pressed in the case of the button-type watch shown in figure 2), the hands point to the already set alarm time. It rotates clockwise at high speed, and when the alarm time arrives, it stops and continues to display the alarm time. A buzzer will sound when you arrive. To adjust the alarm time, in this state, if using the IJ watch type, rotate crown 2 counterclockwise (if using the button type, press button 18a) and rotate the hands clockwise, or For crown type, rotate crown 2 to the opposite side (for button type, rotate crown 1)
8b) and rotate the pointer counterclockwise.

When the alarm time has been confirmed or corrected and crown 2 is returned to its original first position (or when button 18e is pressed for a button type), the hands will move counterclockwise toward the normal time. The clock rotates at high speed, and when the normal time is reached, it is fast forwarded (stops and returns to normal hand movement. The time when the crown 2 is pulled out is also timed, and the clock does not become late due to this operation, and the time is correct.) to return to.

When you pull out the leash 2 to the second position and set the needle to the 3rd position 2'' (or in the button type shown in Figure 2, press button 1).
8C), the S4 switch turns on and continues to reset the tire counting circuit 52 via the OR circuit 54 to prevent it from counting, and also continues to reset the frequency dividing circuit in the latter stage of the timing circuit 21. Stop outputting the 20 second periodic signal. Further, one input of each of AND circuits 61 and 62 is maintained at H level. If you leave the watch as it is, the hands will not move, which saves power, and it can also be used to store the watch. In this state, if the crown type is used, crown 2
By rotating the button (or pressing the button on the button type), you can align the needles. That is, when the switch SL is switched, a correction pulse is output from the input signal waveform shaping circuit 31 in proportion to the number of times of switching, and the AND circuit 61
It is transmitted to Or (ro) road 26.67 via.
The output of the 1-OR circuit 26 is the drive circuit 2 for forward rotation.
5 outputs a forward rotation drive pulse to rotate the motor 28 in the forward direction in proportion to the number of times of switching. The pointer is corrected to the positive side.

On the other hand, the output of the OR circuit 67 increases the time count value of the time integration circuit 68 to achieve synchronization with the hand.

If the crown 2 is rotated to the opposite side (or the button is pressed) to switch the switch 82, a correction pulse is similarly output from the input signal waveform shaping circuit 32 in proportion to the switching circuit, and an OR signal is output via the AND circuit 62. The signal is input to the circuit 24 and the time integration circuit 68. The output of the OR circuit 24 causes the reverse rotation drive circuit 26 to output a reverse rotation drive pulse, causing the motor 28 to rotate in reverse every time it is switched. The pointer is corrected on the other side. Also, human input to the time integration circuit 68 reduces its count value and synchronizes it with the hand.

When the Leeuzu 2 is placed in the third position with the hands aligned, or when button 18C is pressed in the button type, it may be in the middle of moving to the alarm time monitor, or when the alarm time monitor is being used. If the time is in the middle of returning to normal time, the interval memory circuit 66
Since the output Q of is at the L level, the output of the AND circuit 71 remains at the L level even if the S switch is input.
Due to the rotation of Leeuzu 2, the SL2 switch is made insensitive during that time, and the reset action of the clock circuit 21 is postponed during that time to prevent the time from going out of order.After a while, when the hands reach the normal time, the 84 switch turn on f
What is to be done is to turn off the switch S, and the operation to return to the normal time display as described above begins. ) The output Q of the interval storage circuit 66 is inverted to H level, and the AND circuit 71
The output also becomes [I level, and the needle alignment operation as described above can be performed.

When pulling out and pushing in the crown 2 as explained above, when you pull out the crown 2 to the second stage and try to set the hands, or when you try to return the crown 2 to the normal position after setting the hands, , - Since it passes through the 81st stage, S, the switch may be turned on momentarily, and when trying to pull out the Leeuzu 2 to the first stage, it may be pulled out to the second stage by mistake, etc. problem occurs.

Regarding the former, the alarm time monitor starts operating every time the hands are set, causing the hands to move and giving the user a sense of distrust. The problem can be solved by inserting it.

Regarding the latter, since there are many opportunities to check or set the alarm time, it is quite possible that you will sometimes get too excited and pull it out to the second step and mess up the time, but it is about 0.5
If a delay circuit having a timer function of approximately seconds is inserted immediately after the 84 switch, it becomes possible for the user to immediately return the Lees 2 to prevent this.

If you monitor the alarm time and leave it as it is (if you leave it at 70 with crown 2 set to the 2nd position or if you press and hold button 18d of a button-type watch), it will automatically reset. The function works. When the S3 switch remains on and one minute passes without any input to the 81.82 switch, S or switch, the output Q of the timer counting circuit 52 is inverted to the H level. As a result of this output, the output of the inverter 53 becomes L level, which acts on the AND circuit 51 to cut off the I Hz signal input to the timer counting circuit 52 and stop counting. The output of 34 is held at L level and S,,S
The switch signal from the switch 2 is cut off to make the SL and S2 switches insensitive, and the output of the AND circuit 65 is set to L level, and the output of the switching circuit 22 is switched to normal hand movement, and the OR circuit 26 drives the forward rotation. The circuit 25 is operated to cause the motor 28 to rotate forward every 20 seconds, and the time integration circuit 68 is caused to integrate the time via the OR circuit 67.

It will automatically return to normal hand movement. Further, due to the H level output of the timer counting circuit 52, the output of the OR circuit 41 of the fast forward signal output circuit 40 becomes H level, and the AND circuit 42 outputs a 64 Hz fast forward signal.
) The fast-forward signal passed through the return alarm time monitor control circuit 64 and the OR circuit 65 decreases the count in the interval storage circuit 66, and the control circuit 64 outputs the fast-forward signal until the count becomes OK. The fast forward signal is transmitted to the alarm time storage circuit 72, the count value of the interval storage circuit 66 is restored, and the OR circuit 24
is transmitted to the reverse rotation drive circuit 26 through the motor 2.
8 in the opposite direction, and the hands are reversed to return to the normal time.

The operation in this area is the same as when the switch S is turned off, as described above. Since the H level output of the timer counting circuit 52 is input to the warning sound drive circuit 76, a buzzer sound is emitted from the buzzer 78 through the OR circuit 77 to notify that the automatic return function has been entered. Even if the user leaves the crown 2 pulled out to the first click and ignores the warning sound, the alarm time memory circuit 72, time integration circuit 68, and coincidence circuit 76 will continue to operate in the same state as normal. When the alarm time comes, an alarm sound will be emitted. This is because it can be assumed that the alarm will be left alone after checking the alarm time, so even if the alarm is used incorrectly, the alarm will continue to fulfill its mission. After returning Leeuzu 2 to the first position again, the second
If the user presses the button 18e and then the button 18d in the button type, the time-up of the timer counting circuit 52 will be reset and will return to normal operation. Alarm time monitoring, alarm time adjustment, etc. can be used again without any confusion.

The alarm time storage circuit 72, the time integration circuit 68, and the interval storage circuit 66 are preferably counter circuits with a count capacity of 12 hours so that they can be synchronized with the pointer even if overflow occurs due to correction or a normal long sword. In addition, the cholera counting and storage circuit can be replaced with RAM if the entire system is made into a microcomputer and the execution is operated by the CPU.At this time, the fast-forward signal output of this embodiment in which the fast-forward signal is widely wired can be used. The circuit 40 will be a small-scale one that is likely to be included in the forward and reverse rotation drive circuits 25 and 26, or it can be replaced with a system using 1(, OM, R, AM).

Furthermore, although a wristwatch with an alarm is given as an example, the same purpose can be achieved by setting the second time to the measured time in a chronograph watch, the remaining time in a timer, or the time in another country in a world clock. I can do it.

As described above, the present invention enables the display switching operation to be performed immediately in accordance with the command by operating an external operating member such as a watch or button, so that the operation corresponds well to the movement of the clock and hands, and even if the command is made immediately before. Even if a new command is issued before the display change is completed, the command will be followed immediately, so the operation of the command, clock, and hands are closely linked, making the operation easy to understand. It is also possible to eliminate the need for display means to indicate the status of the watch and hands (normal status or alarm display status), and it is possible to realize a watch with additional functions that maintains the good watch design as a single unit. .
