Abstract

PURPOSE:To prevent misconception whether the time displayed is an alarm time or a current time with a simple construction by normally turning a hand to indicate an alarm time or reversing it to return the indication to current time. CONSTITUTION:In response to the closing of a switch S3 through a switch input signal control circuit 107, a quick advance signal circuit 112 operates to increase the counts of an interval counting circuit 66 and the contents of the counting of an alarm time memory circuit 72 decreases. At the same time, a hand is turned normally with a normal rotation driving circuit 25 to which a quick advance signal is applied, a motor 28 and the like until the contents of the circuit 72 coincides with counts of current time with a time accumulation circuit 68 and the circuit 112 is disabled with a coincidence circuit 73, which causes an alarm time to be indicated. Likewise, according to the contents or the like of the circuit 66, the hand is reversed quickly to return the indication to the current time. This prevents miconception whether the time displayed is an alarm time or a current time with a simple construction dispensing indication for identification thereof or the like.

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a pointer display type timepiece equipped with an alarm function, and more specifically to a pointer display type timepiece in which the same hand is used for both displaying the alarm time and normal time. Regarding alarm clocks.

An object of the present invention is to provide the following advantages when the same pointer is configured to selectively display either the alarm time or the normal time.
The purpose is to prevent the user from becoming confused as to which point the pointer is displaying.More specifically, when the pointer is changed from one display to the other by external operation, which display will be displayed next? □ The user is asked to confirm whether the pointer moves to □ by the way the pointer moves, and the pointer or pointer is newly displayed. This is to prevent the user from making a mistake as to whether the second time is an alarm time or a normal time.

The following will explain based on the drawings. FIG. 1 is an explanatory diagram of the operation of the pointer representing one embodiment of the present invention.

When the lews 2 are pulled out one step, the mandarin duck 4 rotates clockwise, the switch spring 4b comes into contact with the pattern 5, and S3 is turned on. At this time, the switch wheel 7 is in the same position as normal, but since the corner 6b is long, the rotation of the crown 2 is transmitted t'L, and when the crown 2 is rotated toward you, the contact spring 8 is activated intermittently in a pattern. 9 to intermittently turn on S1, and rotate in the opposite direction to intermittently turn on st in the same way.

The switch wheel 7 remains at the same position as in the normal case, and the rotation of the rear wheel 2 operates in the same manner as when it is pulled to the first stage. When the button 12 is in the first pull position, the contact 13a contacts the pattern 14 to turn on the button S.

FIG. 3 is a block diagram showing the basic signal flow of the alarm wristwatch shown in FIG. 2. Timing circuit 2
The output of 1 is input to the switching circuit 22. Switching circuit 22
One output is input to the forward rotation drive circuit 25 and the time integration circuit 68.

The output signal of the forward rotation S drive circuit 25 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 clock circuit 21
The output of the 20 second periodic signal is inputted to the forward rotation drive circuit 25 via the switching circuit 22. The drive signal output of the drive circuit 25 formed in accordance with this is input to the motor 28,
The motor 28 rotates one pitch every 20 seconds. The rotation is.

The speed is reduced by the gear train, and the pointer moves forward (clockwise). The 20 second periodic signal outputted from the switching circuit 21 is also input to the time integration circuit 68, and increases the count value of the counting circuit therein.

The output of the coincidence circuit 76, into which the contents of the counting circuit in the alarm time storage circuit 72 and the contents of the counting circuit in the time integration circuit 68 are input, is used to output the sounding element and the drive circuit for making it sound. When the count value of the alarm time storage circuit 72 and the count value of the time integration circuit 68 match, the buzzer starts sounding.

The switches Sl, S2, S8, and S4 shown in FIG. 2 are connected to a switch input signal control circuit 1o7.

The output of the control circuit 107 includes a switching circuit 22, a forward rotation drive circuit 25, a reverse rotation drive circuit 26, a time integration circuit 68,
It is input to the interval storage circuit 66 and the fast forward signal control circuit 40.

further connected to the fast forward signal control circuit 112.
The outputs of the interval memory circuit 66 and the alarm time memory circuit 7
2. It is input to the forward rotation drive circuit 25 and the reverse rotation drive circuit 26. As for the interval storage circuit 66, the output from the switching circuit 22 is also input to its input terminal, and the fast-forward ° signal control circuit 112 is connected to its output terminal. - The output of the number circuit 76 is the fast forward signal control circuit 1
12 is also input. The switch S is connected to a buzzer device 78. The output of the reverse rotation drive circuit 26 is input to the motor 28.

S. When the switch is turned on, a fast-forward signal is output from the fast-forward signal control circuit 112 in response to a control signal from the switch input control circuit 107. This fast-forward signal increases the count value of the interval storage circuit 66 (counts up), and decreases the count value of the alarm time storage circuit 72 (counts down). Furthermore, the fast forward signal is
The forward rotation drive circuit 25 is activated to output a fast forward drive signal to the motor 28. Therefore, the pointer is moved in the forward direction. When the alarm time and the normal time match, that is, when the count values of both the alarm time storage circuit 72 and the time integration circuit 68 become equal, the output of the minus number circuit 76 is input to the fast-forward signal control circuit 112, and the fast-forward signal is Output is stopped. As a result, the hand stops with the alarm time indicated, and the transfer of the contents of the alarm time storage circuit 72 to the interval storage circuit 66 is completed. This state is the alarm time monitoring state. In order to prevent the time from going out of order even if left in this state for a long time, the 20 second cycle signal from the switching circuit 22 is not input to the forward rotation drive circuit 25, but is switched to the interval storage circuit 66 and input. Ru.

If the SI or S2 switch is operated in this state, the alarm time will be corrected. When the switch Sl or S is turned on, a correction pulse is output from the switch input signal control circuit 107 to the forward rotation drive circuit 25 or the reverse rotation drive circuit 26. The drive signals from these drive circuits 25 or 26 cause the motor 2a to rotate forward or backward, and rotate the pointer forward or backward. At the same time, the correction pulse is also input to the interval memory circuit 66, and in order to increase or decrease the count value, the correction amount of the pointer is maintained in synchronization with the count value of the interval memory circuit 66.

Next, 8. When the switch is turned off, the fast forward signal control circuit 1 responds to the output of the switch signal control circuit 107.
12, a fast-forward signal formed by a fast-forward signal output circuit 40 is output. This fast forward signal is transmitted to the reverse rotation drive circuit 26, and the motor 28 rotates in the reverse direction according to the reverse rotation drive signal generated there. At the same time, the fast-forward signal is also input to the interval memory circuit 66 to decrease its count value.Furthermore, the above-mentioned fast-forward signal is also input to the alarm time memory circuit 72 to increase its count value. , the contents of the count value of the interval storage circuit 66 are transferred into the alarm storage circuit 72. It operates in various ways.

When the count value of the interval storage circuit 66 becomes 0, a stop command signal is then issued to the fast-forward signal control circuit 112, and the output of the fast-forward signal is stopped. At this time, the watch has returned to the normal time display, and the 20 second periodic output from the switching circuit 22 is also being supplied to the forward rotation drive circuit 25, returning to the original normal hand movement operation state. There is.

If the sl or S2 switch is switched while the S4 switch is on, the time is normally corrected.

That is, according to the switching of the sl or S2 switch, a correction pulse from the switch input signal control circuit 107 is transmitted to the forward rotation drive circuit 25 or the reverse rotation drive circuit 26.

As in the case of alarm time adjustment described above, the motor 28 is rotated in the forward or reverse direction by the drive signals from the drive circuits 25 and 26. At the same time, the correction pulse is transmitted to the time integration circuit 6
8 is also input, and operates to increase or decrease the count value therein to maintain synchronization with the pointer.

The output of the OR circuit 24 is input to a reverse rotation drive circuit 26 that forms a signal waveform for rotating the motor 28 in reverse, and is further connected to an output circuit 27 . Alarm time memory circuit 72
The output of the coincidence circuit 76 which inputs the output of
The output is also input to an alarm time sound drive circuit 75 which forms a chime sound signal to be sounded at the alarm time. The output of an OR circuit 77 that connects a warning sound drive circuit 76 that forms a signal for emitting a simple sound and an alarm time sound drive circuit 75 is manually input to a buzzer device 78.

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 26, 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 an OR circuit 67 to a time integration circuit 68.
The counted contents are added up (up-counted). Eventually, when the contents of the alarm time memory circuit 72 match, a matching signal of H level is output from the matching circuit 76, and when the S@ switch is on (when the button 12 is pulled out one step in Fig. 2). The -1km signal is transmitted to the alarm time sound drive circuit 75, and the output sounding motion signal is inputted to the buzzer device 78 via the OR circuit 77.
A sound is emitted.

Alarm: -7, time monitor momentary (when the Ss switch is turned on, that is, when the crown 2 is pulled out one step in FIG. 2), the output of the inverter 36 becomes L level, and the one-shot circuit 37 A single signal is output. This signal passes through the OR circuit 54 to the timer counting circuit 5.
2, the interval storage circuit 66 is reset, and their output Q becomes L level. The timer counting circuit 52 remains at the L level for one minute, during which time the output of the inverter 56 is.

It's at H level. A 64Hz signal is output from the AND circuit 43 of the fast-forward signal output circuit 40, and the fast-forward signal that has passed through the forward alarm time monitor control circuit 66 increases the count in the interval storage circuit 66 through the OR circuit 69, and then outputs the alarm time. The count in the memory circuit 72 is decreased, and a drive signal with a higher frequency is outputted from the forward rotation drive circuit 25 via the OR circuit 26, thereby causing the motor 28 and the pointer to rotate forward at high speed. The H level signals from the inverter 53, S, and switch make the output of the AND circuit 35 H level, so
The switching circuit 22 outputs a 20 second signal from the lower AND circuit. Therefore, the normal movement of the hands is stopped and the interval memory circuit 6
It acts to subtract the number of times of that signal from the count value of 6. 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 to prohibit further input of the fast forward signal from the fast forward signal output circuit 4o to the alarm time storage circuit 72 and the interval storage circuit 66. The other of the coincidence signals is inputted to the alarm time sound drive circuit 75 via the AND circuit 74 if the Ss switch is on, so that the user can be informed by an alarm sound that the hand has arrived at the alarm time.

To change the sound when there is a match as an alarm sound, a new match sound drive circuit that outputs a signal different from the alarm time sound drive circuit 75 is installed, a match signal is applied to this, and the output is sent to the OR circuit 7 manually. It becomes possible if you improve it so that it does.

If you turn crown 2 in this state, alarm time 1 will be set.
Corrections will be made. S to correct regularity (positive rotation)
, when the switch is switched, a correction pulse proportional to the number of switching is output from the input signal waveform shaping circuit 31, and after passing through the AND circuit 63 (the switch Ss is turned on, and the output of the timer circuit 5o is the timer 1 hour). (The AND circuit 63 passes that pulse.) 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 goes through the OR circuit 54 to reset the timer counting circuit 52 and start the timer from the beginning. 26, the forward rotation drive circuit 25 is actuated for each corrected pulse to output a drive signal, causing the motor 28 to rotate forward, and passing through an OR circuit 69, the count value of the interval storage circuit 66 is increased.

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 switch 82 is switched to correct the reverse side (reverse rotation), the input signal waveform shaping circuit 32 outputs a correction pulse proportional to the number of switches, as in the case of pressure correction, and the AND circuit 34 After passing,
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 causes the reverse rotation drive circuit 26 to act on each corrected pulse to output a reverse rotation drive signal, thereby starting the motor 28. While rotating in the reverse direction, the counted value of the interval storage circuit 66 is decreased through the OR circuit 65.

That is, while the pointer is rotated and corrected in the counterclockwise direction, the interval storage circuit 66 also subtracts the amount by which the difference between the alarm time and the normal time corresponds to the amount of correction.

Next, when the crown 2 is pushed back and the S switch is turned off, the outputs of the AND circuits 66 and 64 are held at the L level, cutting off the inputs of S, , and St, and the AND circuit 6
Since the output of No. 5 is also inverted to the L level, the output state of the switching circuit 22 is returned to the normal hand movement state. Further, the OR circuit 41 of the fast-forward signal output circuit 40 is inverted to H level, and the AND circuit 42 outputs a fast-forward signal of 64 Hz pulse, and the fast-forward signal is sent to the return alarm time monitor control circuit 6.
4. The signal is then input to the OR circuit 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, causing the motor 28 to reverse and rotate the pointer counterclockwise. circuit 6
The counted value of the difference between the normal time and the alarm time stored in 6 is transferred. When the hands are positioned at the normal time, the interval memory circuit 6
The output Q of No. 6 is inverted to H level, causing the return alarm time monitor control circuit 64 to enter, and inhibiting the output of the 64 Hz 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 usage of the watch, the first
I have already written the outline of 5K based on the diagram.

When the Leeuzu 2 is pulled out to the first position, the pointer rotates clockwise at high speed toward the already set alarm time, and when it reaches the alarm time, it stops and continues to display the alarm time.

A buzzer will sound when you arrive.

To adjust the alarm time, in this state, rotate the crown 2 counterclockwise to rotate the hands clockwise, or rotate the crown 2 in the opposite direction to rotate the hands counterclockwise. and execute it. When the alarm time has been confirmed or corrected and the Rieuse 2 is returned to its original normal position, the hands will rotate counterclockwise at high speed toward the normal time, and when the normal time is reached, fast forwarding will stop and the hands will move normally. Return to state. The time the crown 2 is pulled out is also timed, and this action does not cause the watch to slow down, but rather returns to the correct time.

When the crown 2 is pulled out to the second click to set the hands, the S switch turns on, and continues to reset the timer counting circuit 52 through the OR circuit 54 to prevent it from counting, and also to prevent the timer counting circuit 52 from counting. The branch circuit also continues to be reset and stops outputting the signal for 20 seconds. Furthermore, one input of AND circuits 61 and 62 is kept at H level. If you leave the watch as it is, the hands will not move, which saves power, and can also be used to store the watch. This state η
The needles can be set by rotating the needles 1 and 2.

That is, when the switch S 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 is transmitted to the OR circuit 23.67 via the AND circuit 61.

The output of the OR circuit 26 causes the forward rotation drive circuit 25 to output a forward rotation drive pulse, causing the motor 28 to rotate forward 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 6J7 increases the time count value of the time integration circuit 68 to synchronize with the hand. If you turn crown 2 to the opposite side and switch S2,
Similarly, a modified pulse is outputted from the input signal waveform shaping circuit 62 in proportion to the number of times of switching, and is inputted to the OR circuit 24 and the time integration circuit 68 via the AND circuit 62. 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, the input to the time integration circuit 68 decreases its count value and synchronizes with the hand.

In the pull-out and push-in operations of the crown 2 explained above, when you pull out the crown 2 to the second position and try to set the hands, or when you try to return the crown 2 to the normal position after setting the hands, , Once it passes the first stage, the S switch may be turned on momentarily, and when trying to pull out the Rieuse 2 to the first stage, it may be pulled out to the second stage by mistake. problem occurs. Regarding the former, the alarm time monitor operation starts every time the hands are set, causing the hands to move and giving the user a sense of distrust, but S has a delay circuit with a timer function of about 0.5 seconds.

The problem can be solved by inserting it immediately after the switch. Regarding the latter, since there are many opportunities to check or set the alarm time, it is quite possible that you may sometimes get too excited and pull it out to the second stage and mess up the time, but it has a timer function of about 0.5 seconds. Delay circuit 8. If the switch is inserted immediately after the switch, the user can prevent this by immediately returning the rieuse 2. Also, after monitoring the alarm time (when crown 2 is in the first click) or when setting the hands (when crown 2 is pulled out further and moved to the second click), the alarm time display returns to the normal time display. so that the S4 switch works on each circuit, and the crown 2
The S, , and S2 switches are made insensitive during the 0 rotation,
There is also a method of postponing the reset of the clock circuit 21 during that time to prevent the time from going out of order.
．． This can be achieved by constructing a gate circuit that inputs the switch.

When the alarm time is monitored and left as is (when crown 2 is pulled out one click and left as is)
The automatic return function works. S.

If the switch is left on and one minute passes without any input to the S, , S, switch, or S4 switch,
The output Q of the timer counting circuit 52 is inverted to H level. As a result of this output, the output of the inverter 53 becomes L level, so 1. It acts on the AND circuit 51 to cut off the IHz signal input to the timer counting circuit 52 to stop counting, and also holds the outputs of the AND circuits 66 and 64 at the L level so that the output from the S, , S switch is The switch signals of S, , S, and S are insensitive by cutting off the switch signals, and the output of the AND circuit 35 is set to L level, and the output of the switching circuit 22 is switched to normal hand movement, and the OR circuit 23 and forward rotation drive circuit are activated. 25 to cause the motor 28 to rotate forward every 20 seconds, and the time integration circuit 68 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 a fast-forward signal until the count reaches zero.

The fast forward signal is transmitted to the alarm time storage circuit 72, the count value of the interval storage circuit 66 is transferred, and is transmitted to the reverse rotation drive circuit 26 via the OR circuit 24.
The motor 28 is rotated in the reverse direction, and the hands are reversed to return to the normal time. The operation in this area is the same as when the Ss switch for shearing is turned off. Since the [■ level output of the timer counting circuit 52 is input to the warning sound drive circuit 76, the buzzer 78 emits a buzzer sound to notify that the automatic return function has been entered through the OR circuit 77. 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 73 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.

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 synchronize with the hand even if overflow occurs due to correction or normal human power. In addition, these counting memory circuits make the entire system into a microconverter, and the execution is carried out by CP'
If it is operated by U, it can be replaced with FLAM. At this time, the fast-forward signal output circuit 40 of this embodiment, in which the fast-forward signal is widely wired, is connected to the forward and reverse rotation drive circuit 25.2.
6, or 1 (O
It is possible to replace it with a method using M or RAM.

As described above, the present invention depends on the way the hands move, that is, when displaying the alarm time, the alarm time moves forward and is displayed as it is a future time, and when returning to the original normal time, Since the time is in the past compared to the alarm time, it is displayed in reverse to notify the user of the result of the operation, making it easy to understand and eliminating the need for a special display to display it, making it easier to design the watch. This has the effect of making it possible to create a wristwatch with an alarm while keeping it simple.

Claims (1)

[Claims] A clock circuit, a motor that rotates in forward and reverse directions, a forward rotation drive circuit and a reverse rotation drive circuit for rotating the motor in the forward and reverse directions, a pointer driven by the motor, and an externally set alarm. Alarm time storage means for storing time, interval storage means for storing the relationship between alarm time and normal time, and fast forwarding for outputting fast forwarding signals in accordance with each of the first and second states of the switch created by external switching. a signal output means; in the first state of the switch, the motor is rotated in the forward direction by an output signal of the motor forward rotation drive circuit in response to the signal of the fast-forward signal output means, thereby adjusting the alarm time according to the contents of the alarm time storage means; The alarm time is displayed by rapidly moving the hand in the forward rotation direction from the determined alarm time, and in the second state of the switch, the motor is controlled by the output signal of the reverse rotation drive circuit in response to the signal of the fast-forward signal output means. The pointer display type alarm clock is characterized in that by rotating the pointer in the opposite direction, the pointer is rapidly moved in the reverse rotation direction to the normal time determined by the contents of the interval storage means, thereby returning to the normal time display. .
