Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a clock device with an alarm, and particularly to a clock device with an alarm that displays time using an optical display device.

Conventionally, the alarm operation of a clock device with an alarm was performed by a mechanical switch. but,
Mechanical switches require a large number of parts, such as a substrate on which the electrodes are placed, an insulating plate, and a conductive rubber switch, resulting in a large number of man-hours, high costs, and difficult sealing. .

Further, a switch for operating an alarm, such as an alarm silencer switch, is not a type of switch that is used all the time, but when the alarm is to be silenced, it needs to be placed in a position where it can be easily operated. However, since conventional switches were mechanically formed as described above, they were often provided on the side of the watch body due to their structure. For this reason, there were problems in that the operability of the switch was not sufficient when the alarm was activated, and the size of the display surface for displaying the time was limited by the mounting position of the switch, and furthermore, miniaturization of the entire clock device was hindered. . Furthermore, mounting the switch on the side of the watch body poses a major design constraint, and is not desirable in today's watch devices where fashion is becoming increasingly popular.

The present invention was made in view of such conventional problems, and its purpose is to reduce costs and facilitate sealing by using a touch switch to operate an alarm, and to make this switch substantially transparent. An object of the present invention is to provide a clock device with an alarm that is provided on the display surface as a structure and can display the position using an optical display element only when necessary, thereby improving operability, downsizing, and eliminating design constraints. .

In order to achieve the above object, the present invention includes a time clock circuit that clocks a reference signal and outputs a time signal, an alarm storage circuit that can set and store an arbitrary alarm time signal, and a time clock circuit that clocks a reference signal and outputs a time signal. a matching circuit that outputs a matching signal when the matching signals match, an alarm sound generation circuit that notifies an alarm sound by outputting the matching signal, and a display selection signal that corresponds to the time signal or the alarm time signal by operating a confirmation touch switch. a display selection circuit that outputs a switching signal; a display switching circuit that inputs the time signal and the alarm time signal and outputs a signal corresponding to the display selection signal; and a display switching circuit that outputs a signal corresponding to the display selection signal; a set/non-set circuit that outputs a set signal for enabling the operation of the alarm sound generation circuit and a non-set signal for disabling the alarm sound generation circuit by operating a set touch switch and a reset touch switch. In the watch, position indicators are formed at corresponding positions of the set touch switch and the reset touch switch to indicate the position of each touch switch, and are illuminated by the output of an alarm time display selection signal from the display selection circuit, The present invention is characterized in that it is provided with a set/non-set touch switch position display circuit that changes the lighting form in response to the output states of the set signal and the non-set signal.

Next, a preferred embodiment of the alarm clock device of the present invention will be described.

FIG. 1 is an explanatory diagram of the display surface of the timepiece device of the present invention. Optical display elements for displaying the time, for example, a set of segment display elements 12, are arranged in the center of the display surface 10, and a confirmation touch switch 14 is arranged in the upper right corner of the display surface 10, and a stop touch switch 16 is arranged in the lower left corner. , a set touch switch 18 and a reset touch switch 20 are located in the upper left corner.
are provided for each. The electrodes of each of these touch switches 14, 16, 18, and 20 are formed with transparent switch electrodes, and their positions cannot normally be confirmed from the outside.
Therefore, at a position corresponding to the confirmation touch switch 14, there is a bell-shaped confirmation touch switch position indicator (hereinafter referred to as an alarm mark) 22 formed with an optical display element such as an LED, LCD, or ECD. Touch switch position indicators 24, 26, 2 are provided and have similar optical display elements for indicating the position of each touch switch at positions corresponding to other touch switches 16, 18, 20.
8 is provided.

Since the alarm clock device is often used as an alarm clock, for example, among the touch switches 14, 16, 18, and 20, the stop touch switch 16 for stopping the alarm should be located at a position with particularly good operability. is preferred. Therefore, when such a need is great, the squealing touch switch 16 is moved to the display surface 1 as shown in FIG. 2, for example.
It is also possible to provide a large number in the center of 0.

FIG. 3 shows each of these touch switches 14, 16,
18 is an explanatory diagram showing operations 18 and 20. FIG.

In FIG. 3, A is in a state where the normal time is displayed. In this state, only the alarm mark 22 is lit, and the other position indicators 2
4, 26, and 28 are all off. Therefore, the time represented by the segment display element 12, for example "12:38", is displayed on the display surface 10, and the alarm mark 22 is only lit otherwise. Therefore, the time is displayed in a very easy-to-read manner without any other unnecessary display. If an alarm is set, the alarm mark 22 flashes to notify the user of this.

However, in this state, the content of the alarm cannot be sufficiently determined. This determination is made using the touch switch 1 for confirmation.
This is done by touching 4. Note that the confirmation touch switch 14 is formed with a transparent electrode, so its position cannot be determined.
The alarm mark 22 is the confirmation touch switch 14
Since the confirmation touch switch 14 is provided at a position corresponding to the alarm mark 22, the confirmation touch switch 14 can be easily operated by touching the vicinity of the alarm mark 22 on the display surface 10.

When the alarm touch switch 14 is touched in this way, as shown in B and C of FIG.
Along with the alarm mark 22, one of the setting touch switches 26 and 28 starts blinking, indicating that the clock device has entered the alarm confirmation state, and the segment display element 12 displays the currently set Alara time, e.g. 6:00" and press the touch switch 1 for setting and resetting.
Position indicators 26 and 28 provided at positions 8 and 20 light up. Here, when the clock device is in the alarm setting state, the setting touch switch position display 26 on the display surface 10 blinks to notify this, as shown in FIG. 3B; 3C, the reset touch switch position display 28 on the display surface 10 blinks to notify this. If no touch operation is performed after that, the built-in timer function works and the display screen 10 returns to the state shown in FIG. 3A after about 5 seconds.

Further, when the alarm touch switch 14 is touched and the set state of the alarm shown in FIG.
Just touch the button. As a result, the timepiece device is switched from the set state to the non-set state, and the display surface 10 is also switched from the state shown in B in FIG. 3 to the state shown in C in FIG. On the other hand, alarm touch switch 1
When the alarm non-set state shown in FIG. 3C is confirmed by the touch operation 4, if the alarm non-set state is to be changed to the alarm set state, the set switch 18 may be touched. As a result, the timepiece device is switched from the non-set state to the set state, and the display surface 10 is also switched from the state shown in C in FIG. 3 to the state shown in B in FIG.

As described above, according to the present invention, it is possible to check whether an alarm is set or not and to set and reset the alarm easily and accurately by touching the switch.

Also, if the alarm time is displayed on the clock device, for example, “6:
00, the alarm will sound when the current time reaches the alarm time of 6:00, as shown in FIG. 3D. In this case, the display surface 10
Above, the stop touch switch position display 2
4 lights up. At this time, by touching the stop touch switch 16 indicated by this position display 24, the alarm will stop sounding, and the sound stop touch switch position display 24 will go out, as shown at E in FIG.

In this way, when the alarm starts sounding, the present invention
The position of the stop switch 16 is clearly shown on the display surface 10 by a position display 24, and the stop switch 16 indicated by the position display 24 is
You can easily turn off the alarm by just touching the button, providing excellent operability.

Next, an embodiment of an electric circuit for realizing the above-mentioned alarm function will be described based on FIG. 4.

The frequency divider 40 divides the oscillation output of the oscillator 42 to approximately
It outputs a clock pulse φ ₁ of about 0.5 Hz, and also outputs a divided frequency value to the clock circuit 44 .
The clock circuit 44 counts this frequency-divided output to time the current time, and inputs this clock output to the decoder driver 46 to cause the segment display element 12 to display the current time, for example, "12:38". Further, the alarm storage circuit 48 stores an alarm time, for example, "6:00", and this alarm storage circuit 48 stores the alarm time in the decoder driver 46.
is input to cause the segment display element 12 to display the alarm time, for example, "6:00". In this embodiment, since only one set of segment display elements 12 is provided, it is necessary to select the input to the decoder driver 46 as either the current time or the alarm time. A display switching circuit 50 for this purpose is provided at the input stage to the decoder driver 46, and either the current time or the alarm time is selected and input to the decoder driver 46 based on a switching signal from the outside.

The matching circuit 52 determines whether the current time outputted from the clock circuit 44 and the alarm time outputted from the alarm storage circuit 48 match or not, and when they match, outputs an H level matching output to the alarm circuit. 54.

The alarm circuit 54 includes a flip-flop 56 which inverts its output in synchronization with the coincidence output of the coincidence circuit 52. The inversion of the output of the flip-flop 56 activates a notification circuit 58 to issue an alarm notification. Further, a sound stop touch switch position display 24 is connected to the output stage of the flip-flop 56, and lights up at the same time as alarm notification is started to display the position of the sound stop touch switch 16 on the display surface 10. The switch output of the chirp touch switch 16 whose position is displayed in this manner is input to the reset terminal of the flip-flop 56. Therefore, by touching the sound stop touch switch 16 during alarm notification, the flip-flop 56 is reset, the alarm is stopped, and the position display 24 is turned off.

Note that this alarm circuit 54 does not necessarily cause an alarm operation when the coincidence circuit 52 receives a coincidence output. When the clock device is in the alarm non-set state, the alarm must not be activated even if a coincidence output is input. For this reason,
A matching circuit 52 is provided at the input stage of the flip-flop 56.
An AND gate 60 between the output of the output and the alarm set signal is provided, and the alarm circuit 54 is configured to operate only when a coincidence output is input from the coincidence circuit 52 while the set signal is input to the AND gate 60. has been done. A flip-flop 62 outputs the set signal to the AND gate 60.

This flip-flop 62 is connected to the set touch switch 18 and the reset touch switch 2.
The circuit is configured such that the output is switched by 0. That is, when the setting touch switch 18 is touched, the switch output from the switch 18 is input into the input terminal of the flip-flop 62, and the output of the flip-flop 62 is changed from the L level output as the alarm non-setting signal to the alarm output. Switching and inverting the output to H level as a set signal. The switch output obtained by touching the reset touch switch 20 is input to the reset terminal of the flip-flop 62, resets the flip-flop 62, and changes the output of the flip-flop 62 from the H level output as the alarm set signal to the alarm output. Switching and inverting the output to L level as a non-set signal.

Note that these touch switches 18 and 20 are provided on the display surface 10, so they can be used to set and set alarms.
Even if you do not intend to switch to reset, you may accidentally perform a touch operation. In order to prevent the state of the flip-flop 62 from being reversed in such a case, the touch switches 18 and 20 are connected to each input terminal of the flip-flop 62 via AND gates 64 and 66 whose other input terminals receive an alarm confirmation signal. , when the alarm confirmation signal is not input to each gate 64, 66, input of the switch output from each touch switch 18, 20 to flip-flop 62 is prevented.
That is, each touch switch 18, 20 is controlled to be valid only while the alarm confirmation signal is being output.

The output terminal of the flip-flop 70 to which the switch output of the alarm touch switch 14 is inputted is normally controlled so that Q=L level and =H level. The output from this output terminal acts as a current time selection signal for the display switching circuit 50, causing the display switching circuit 50 to select the current time output from the clock circuit 44, and cause the display element 12 to display the current time. The output of the output terminal Q is connected to an AND gate 7 provided at the input stage of the touch switch position display 26 for setting and the touch switch position display 28 for reset.
2,74. Note that since Q=L level, the AND gates 72 and 77 are closed and the respective position indicators 26 and 28 are turned off. Further, the output of this output terminal Q is input to an OR gate 76. The output of the output terminal Q of the flip-flop 62 is also input to this OR gate 76.
The OR output is input to a NAND gate 78. The clock pulse Φ ₁ output from the frequency divider 40 is also input to this NAND gate 78 , and this NAND output is input to the alarm mark 22 . Therefore, this alarm mark 22 is normally lit to indicate the position of the alarm touch switch 14.

Next, when the touch switch 14, whose position is indicated by the alarm mark 22, is touched, the output of the flip-flop 70 is inverted, and Q=H level.
= L level. Here, the output of the output terminal Q acts as an alarm time selection signal for the display switching circuit 50, causing the display switching circuit 50 to select the alarm time stored in the alarm storage circuit 48,
The alarm time is displayed on the display element 12.

Further, the output terminal Q of the flip-flop 70 is inputted to the AND gates 72 and 74 as described above, and when Q=H level, this gate 7
Other signals input to gates 2 and 74 cause gate 7
No. 2, 74 becomes H level and lights up the position display of the output stage. Here, 80 is a NAND gate between the output of the output terminal Q of the flip-flop 62 and the clock pulse _Φ1 of the frequency divider 40, and its NAND output is input to the AND gate 72.
Further, 82 is a NAND gate between the output of the output terminal of the flip-flop 62 and the clock pulse _Φ1 of the frequency divider 40, and its NAND output is input to the AND gate 74. Therefore, each position indicator 26, 28 lights up when the output terminal Q of the flip-flop 70 is at Q=H level. At this time, for example, if the flip-flop 62 is outputting an alarm set signal of Q=H level, the output of the NAND gate 80 changes from the H level to the L level in synchronization with the clock pulse _Φ1 , so the setting touch switch position display 26 flashes. Conversely, when the flip-flop 62 is outputting an alarm non-setting signal of =H level, the reset touch switch position display 28 flashes.

As mentioned above, while the position indicators 26 and 28 are lit, the output terminal Q of the flip-flop 70 is
is Q=H level. The H level of the output terminal Q is inputted to the AND gates 64 and 66 provided at the output stages of the touch switches 18 and 20 as the above-mentioned alarm confirmation signal. Therefore, switching the alarm state using the touch switches 18, 20,
In other words, switching between set and non-set is performed using position display 2.
This is possible while 6 and 28 are lit.

Further, 84 is a timer circuit which automatically returns the flip-flop 70, the output of which has been changed by a touch operation of the alarm touch switch 14, to its original state after a certain period of time has elapsed. When the flip-flop 70 is in a normal state, the timer circuit 84 is forcibly controlled to a reset state by the output of its output terminal = H level, and when the output of the flip-flop 70 is inverted by operating the touch switch 14, it becomes = L level and reset. is released and starts counting clock pulses _Φ1 . After a predetermined time period when this count reaches a certain value, the timer circuit 84 outputs a count-up signal, resets the flip-flop 70, and inverts its output. At the same time, the output of the output terminal also becomes high level and the timer circuit 8
4 is also in the reset state.

The embodiment of the present invention has the above-mentioned structure, and its operation will now be explained based on the explanatory diagram of switch operation shown in FIG. 3 and the time chart shown in FIG. 5.

First, consider the case where the clock device is displaying the normal time as shown in A of FIG. In this state, the alarm setting status cannot be confirmed. To confirm this, when the confirmation touch switch 14 is touched at time _t1 in the time chart shown in FIG. 5, the switch output from the touch switch 14 inverts the output of the flip-flop 70, causing the clock to confirm the alarm. Switch to state.
At this time, due to the inversion of the output of the flip-flop 70, the input of the display switching circuit 50 is switched, and the display element 12 displays the alarm time stored in the alarm storage circuit 48, and the alarm mark 22 is set to indicate the alarm. It repeats blinking at about 0.5Hz in synchronization with clock pulse _Φ1 , regardless of whether it is set or not. Further, since the H level output of the output terminal Q of the flip-flop 70 is inputted to the AND gates 64 and 66 as the above-mentioned confirmation signal, the switch outputs of the touch switches 18 and 20 can be inputted to the flip-flop 62.

When the timepiece device, which has been switched to the alarm confirmation state in this way, enters the alarm setting state, the display surface 10 switches from the state shown in A to the state shown in B in FIG. This is because the alarm is in the set state because the output of the flip-flop 62 is Q=H level and =L level. At this time, the output Q of the flip-flop 62,
and the time chart for position displays 26 and 28 is the 5th
It is shown in A of the figure. That is, since the output of the flip-flop 62 is Q=H level and =L level, the NAND output of the NAND gate 80 repeatedly turns on and off in synchronization with the clock pulse, and this changes the setting touch switch position display 26 via the AND gate 72 to approximately 0.5 Hz. blinks at a certain level to indicate that the clock device is in the set state. Also,
The NAND output of the NAND gate 82 becomes H level, which causes the reset touch switch position indicator 28 to light up via the AND gate 74. Then, I touched the confirmation touch switch 14.
At t ₄ o'clock, a certain period of time has passed since t ₁ o'clock, the timer circuit 84 counts up and the flip-flop 7
0 is reset, and the timepiece device automatically returns from the state shown in B in FIG. 5 to the normal time display state shown in A in FIG.

Further, when the timepiece device which has been switched to the alarm confirmation state is in the alarm non-setting state, the display surface 10 switches from the state shown in A to the state shown in C in FIG. 3. This is because when the alarm is in the non-set state, Q=L level and =H level are output from the output terminal of flip-flop 62. The output Q of the flip-flop 62 and the time chart of the position indicators 26 and 28 at this time are shown in FIG. 5B. That is, since the output of the flip-flop 62 is Q=L level and =H level, the NAND gate 82
The NAND output goes high in synchronization with clock pulse _Φ1 .
The level changes to L level and this is AND gate 7
Touch switch position display for reset via 4
8 blinks at a frequency of approximately 0.5Hz to indicate that the clock device is in a non-set state. Further, the NAND output of the NAND gate 80 becomes H level, which causes the set touch switch position display 26 to light up via the AND gate 72. Then, at t ₄ o'clock, a certain period of time has elapsed since t 1 _o'clock when the confirmation touch switch 14 was touched, the timer circuit 84
counts up and resets the flip-flop 70, and the clock device changes from the state shown at C in FIG. 4 to A.
The display automatically returns to the normal time display state shown in .

Next, as shown in FIG. 3B and C, the operation of switching the clock device which is in the alarm confirmation state from the alarm setting state to the non-setting state or vice versa will be explained.

First, when the timepiece device is in the confirmation state shown in FIG. 2B, if the alarm is to be switched from the set state to the non-set state, the reset touch switch 20 may be touched. In the time chart shown in A of FIG. 5, this time is designated as _t2 .
As a result, the switch output of the touch switch 20 is input to the flip-flop 62, the output of the flip-flop 62 is inverted, and the clock device is switched to the alarm non-setting state. Then, the display screen 10 switches from the state shown in B to the state shown in C in FIG. 3, confirming that the alarm has been reset.

Further, when the clock device is in the confirmation state shown in FIG. 3C, if the alarm is to be switched from the non-set state to the set state, the setting touch switch 18 may be touched. In the time chart shown in FIG. 5B, this time is designated as _t3 . As a result, the switch output of the touch switch 18 is input to the flip-flop 62, the output of the flip-flop 62 is inverted, and the timepiece device is switched to the alarm set state. Then, the display screen 10 switches from the state shown in C to the state shown in B in FIG. 3, confirming that the alarm setting has been performed.

Next, the alarm notification operation of this embodiment will be explained based on the time chart shown in FIG.

For example, consider a case where an alarm time of 6:00 o'clock is stored in the alarm storage circuit 48 and the clock device is also in an alarm set state, that is, the output Q of the flip-flop 62 is set to H level.

Here, when the clock circuit 44 outputs the current time 6:00, the coincidence circuit 52 determines this and the output of the coincidence circuit 52 switches from the L level to the H level. Let this time be _t5 in the time chart shown in FIG. Since the output of the flip-flop 62 inputted to one input terminal of the AND gate 60 is at H level as described above, the coincidence circuit 52
The output is input to the flip-flop 56 as is. Therefore, at _t5 when the output of the matching circuit 52 is inverted from L level to H level, the flip-flop 5
The output of No. 6 is also switched to Q=H level and =L level.

As a result, the sound stop touch switch position indicator 24 lights up as shown at D in FIG. 3, and the sound stop touch switch 16 is positioned on the display surface 10, and the notification circuit 58 is driven to start alarm notification.

At this time, the user can confirm the position of the sound stop touch switch 16 by the sound stop touch switch position display 24 lit on the display surface 10. The user can stop the alarm from sounding by simply touching the sound stop touch switch 16 whose position is displayed on the display screen 10. That is, when the stop switch 16 is touched at time _t6 in the time chart of FIG.
The flip-flop 56 is reset and its output is inverted to Q=L level and =H level, and the alarm is silenced and the alarm is turned off and the silence touch switch position display 24
The lights also go out. The display surface 10 then switches to the state shown from D to E in FIG.

FIG. 7 is an explanatory diagram showing another embodiment of the present invention.

In this embodiment, in addition to the touch switches mentioned above, the display surface 10 is provided with a snooze touch switch 30 that stops alarm notification for a certain period of time, for example, about 5 minutes. The electrode of this snooze touch switch 30 is also a transparent electrode like the electrodes of the touch switches described above. Therefore, the user must
A snooze touch switch position indicator 32 having an optical display element for indicating the position of this switch 30 is provided at a position corresponding to the snooze touch switch 30 on the top.

Note that the display surface 10 shown in FIG. 7 includes a segment display element 12, various touch switches 14, 16, 18, 20, 30, and position indicators 22, 24, 26, 28, 32 on the same panel. If necessary, as shown in FIG. 8, for example, the touch switches 14, 16, 18, 20, 30, position displays 22, 24, 26, 28, 32, and the segment display element 12 may be provided on separate panels. .

In this embodiment, since the snooze touch switch 30 is provided, the electric circuit is constructed as shown in FIG. 9. Since this electric circuit differs from the electric circuit shown in FIG. 4 only in the alarm circuit 54, the description of the parts other than the alarm circuit 54 will be given the same reference numerals and the description thereof will be omitted.

First, the output terminal Q of the flip-flop 56 is
One-shot circuit 100 and OR gate 102
The other output terminal is input to the reset terminal of the flip-flop 104 via an OR gate 101. The output terminal Q of the flip-flop 104 and the output terminal Q of the flip-flop 56 are input to an AND gate 106, respectively.
Therefore, the matching circuit 52 outputs an H level signal when the alarm time and the current time match, and the output of the flip-flop 56 is switched via the AND gate 60, so that the output of the flip-flop 56 becomes Q=
Considering the case where the output Q of the flip-flop 56 becomes the H level and the L level, the reset of the flip-flop 104 is canceled when the output of the flip-flop 56 becomes the L level, and the output Q of the flip-flop 56 becomes the H level, so that the one-shot circuit is activated. 100 outputs a pulse with a constant width and inverts the output of flip-flop 104 to Q=H level via OR gate 102. Since the outputs of the flip-flops 56 and 104 are at Q=H level, the AND gate 106 drives the notification circuit 58 provided at its output stage to start notifying the alarm, and lights up the alarm touch switch position display 32. do.

Furthermore, the output terminal of the flip-flop 56 is 3
The count output of this counter 110 is input to an OR gate 112, and this OR gate output is connected to an inverter 114.
is input to the AND gate 116 via.
Therefore, when the output of the flip-flop 56 becomes Q=H level or =L level, the reset of the counter 110 is released. However, since the reset counter 110 is not counting anything at first, all outputs to the OR gate 120 are at L level, and the OR gate output at this point is at L level. Therefore, the output of the inverter 114 becomes H level, and the output of the AND gate 116 to which the output of this inverter 114 and the output of the AND gate 106 described above are input also becomes H level. Therefore, when the notification circuit 58 is activated and the alarm notification starts, the snooze touch switch position display 32
The touch switch position display 24 also lights up. This allows the user of the clock device to
By recognizing the position of the snooze touch switch 30 on 0 and operating the snooze touch switch 30, the watch device can perform a snooze operation.

Snooze touch switch 30 is or gate 1
01 to the reset terminal of flip-flop 104, and via an OR gate 124 to the reset terminal of counter 126. The output of this counter 126 is connected to the other input terminal of the OR gate 102 via a one-shot circuit 128. put it here,
The counter 126 is set as a 5-minute timer that counts the clock pulse _Φ1 outputted from the oscillator 40 when the reset is released, and counts up and outputs the pulse after about 5 minutes.

This 5 minute timer works as follows. That is, when the snooze touch switch 30 is touched to output a pulse, the output pulse temporarily resets the flip-flop 104 and its output Q is inverted to L level. Then, the output of the AND gate 106 also becomes L level, the alarm by the notification circuit 58 is stopped, and the touch switch position display 24 for stopping the sound is also turned off. but,
At the same time, the output pulse of the snooze touch switch 30 clears the count contents of the counter 126, so that the counter 126 outputs a count-up pulse 5 minutes after this time, causing the one-shot circuit 128 to output a pulse for driving the flip-flop 104. Therefore, the output Q of the flip-flop 104 is inverted again to the H level five minutes after being temporarily reset, and the alarm circuit 58 and the touch switch position display 24 for stopping the sound are activated via the AND gate 106.

Further, the snooze touch switch 30 is connected to the entrance end of the counter 110 so that when the above snooze operation is repeated a predetermined number of times, for example, three times, the alarm is completely silenced without any further snooze operation being performed. The output of 110 is input to the reset terminal of flip-flop 56 via OR gate 120. As mentioned above, since the counter 110 counts up by three input pulses, the third snooze operation,
That is, when the snooze touch switch 30 is touched three times, the third pulse output from the switch 32 causes the counter 110 to output a count up pulse. And counter 11
The count up pulse output from 0 resets the flip-flop 56 and resets the flip-flop 5.
6, the operation of the notification circuit 58 is stopped and the position indicators 24 and 32 are also turned off. Further, since the output of the flip-flop 56 becomes H level, the flip-flop 104 and the counters 110, 126 are always in a reset state, and subsequent operation of the snooze touch switch 30 is invalidated.

Further, when the snooze touch switch 30 is operated to stop the alarm from sounding, the alarm will sound again after 5 minutes, so it is necessary to warn the user that the snooze operation is in progress. For this reason,
In this embodiment, the AND gate 1 receives the clock pulse _Φ1 output from the frequency divider 40.
The output terminal of the OR gate 112 is connected to the other input terminal of the AND gate 130, and the output terminal of the AND gate 130 is connected to the other input terminal of the OR gate 118. As a result, when the counter 110 counts the pulses output from the snooze touch switch 30, at least one of the inputs from the counter 110 to the OR gate 112 becomes H level, so the output of the OR gate 112 also becomes H level.
Therefore, the clock pulse Φ ₁ is the AND gate 1
30 to the OR gate 118. Since the other input to the OR gate 118, that is, the output of the AND gate 116, is at the L level while the output of the OR gate 112 is at the H level, the clock pulse _Φ1 is applied to the snooze position display 32 via the OR gate 118. This snooze touch switch position display 32 is blinked. Therefore, even if the alarm is stopped, the user can

You can confirm that the snooze operation is in progress by seeing 2 flashing.

Also, at the reset end of the flip-flop 56, a squealing touch switch 16 is provided as in the previous embodiment.
are connected to each other via an OR gate 120, and the flip-flop 56 is reset by a touch operation of the alarm stop switch 16, thereby completely stopping the alarm from sounding.

The embodiment of the present invention has the above structure, and its operation will be explained next. It should be noted that the feature of this embodiment compared to the previous embodiment is that a snooze operation is added, so this snooze operation will be mainly explained and the explanation of other operations will be omitted.

For example, it is assumed that an alarm time of 6:00 o'clock is stored in the alarm storage circuit 48 and that the clock device is also in an alarm set state, that is, the output Q of the flip-flop 62 is set to H level.

Here, when the clock circuit 44 outputs the current time 6:00, the matching circuit 52 determines this, and the output of the matching circuit 52 switches from L level to H level. Let this time in the time chart shown in FIG. 10 be _ta . Q of the flip-flop 62 inputted to one input terminal of the AND gate 60
Since the output is at the H level as described above, the output of the matching circuit 52 is directly input to the flip-flop 56, and the output of the matching circuit 52 changes from the L level to the H level.
Flip to level. Flip-flop 5 at t _a
The output of No. 6 is also switched to Q=H level and =L level.

By switching the output of flip-flop 56 from H level to L level, flip-flop 104 and counters 110 and 126 are reset, and by switching output Q of flip-flop 56 from L level to H level, one shot is released. A pulse with a constant width is output from the circuit 100, and the output Q of the flip-flop 104 is inverted to H level. For this reason, and gate 1
Since the inputs of 06 are both at H level, the output of this AND gate is also at H level, and the notification circuit 58
alarm notification is started, and the touch switch position display 24 for stopping the ringing lights up on the display screen 10, as shown in FIG. 11D. Thereby, the user can confirm the position of the squealing touch switch 16 on the display surface 10.

Furthermore, at the time t _a when the output of the flip-flop 56 is inverted, the count of the reset-released counter 110 is zero, so the output of the OR gate 112 is also at L level. Therefore, AND gate 130 is closed and inverter 114
The output is at H level. Therefore, at the same time that the output of the AND gate 106 is inverted to H level and alarm notification is started, the H level output of the AND gate 106 is applied to the snooze touch switch position display 32 via the AND gate 116 and the OR gate 118. Then, as shown in FIG. 11D, the snooze touch switch position display 32 is turned on on the display surface 10. This allows the user to confirm the position of the snooze touch switch 30 on the display surface 10.

Here, the user selects whether to perform a snooze operation or a complete stop operation for the alarm by pressing the snooze touch switch 30 shown on the display screen 10.
or can be freely selected using the stop touch switch 16.

Next, the above snooze operation and complete stop operation will be explained respectively.

(1) Snooze operation In this case, the user only has to touch and operate the snooze touch switch 30 indicated by the snooze touch switch position display 32 on the display surface 10. As a result, the alarm stops ringing for a certain period of time, and the display screen 10 switches to the states shown from D to F in FIG. 11.

FIG. 10A is a time chart in this case. When the snooze touch switch 30 is touched for the first time at time t _b in the figure, the flip-flop 104 is reset by the output pulse from the snooze touch switch 30. The output Q of flip-flop 104 is inverted to L level. Therefore, the output of the AND gate 106 also goes to the L level, the alarm by the notification circuit 58 is also stopped, and the sound-off touch switch position display 24 on the display panel 10 is also turned off.

However, the output pulse from the snooze touch switch 30 is counted by the counter 110, and the count output inverts the OR gate 112 to H level, so the AND gate 130 is opened and the clock pulse _Φ1 is sent to the snooze touch switch via the AND gate 130. This snooze touch switch position display 3 is applied to the position display 32.
2 will be flashing. By flashing only the snooze touch switch position display 32 on the display surface 10 in this way, the user can confirm that the timepiece device is in the snooze state.

Further, the output pulse from the snooze touch switch 32 is input to the reset terminal of the counter 126 to reset the counter 126. At the same time, the counter 126 starts counting clock pulses _Φ1 and counts up at time _tc , which is about five minutes after time _tb , and drives the one-shot circuit 128 to output a pulse of a constant width. As a result, the output Q of flip-flop 104 is again inverted to H level, and the output of AND gate 106 also becomes H level. Therefore, the alarm sounds again at time _tc , which is five minutes after the previous stop time _tb , the touch switch position display section 24 for sound-stopping also lights up again, and the display screen 10 is again shown in FIG. 11D. state.
In this state, the output of the inverter 114 continues to be at the L level, so the snooze touch switch position display 32 is blinking.

Here, the snooze touch switch 32
If the snooze operation is performed for the second time at time _td , the alarm will be silenced as before, and the touch switch position display 24 will also be turned off. At this time, the pulses output from the snooze touch switch 30 are counted by the counter 110.

Similarly, when the third snooze operation is performed at time t _f , the counter 110 counts up and outputs a count-up signal of H level, thereby resetting the flip-flop 56 . This results in
The output of flip-flop 56 is Q=L level,
=H level, the operation of the notification circuit 58 is completely stopped, the position indicators 24 and 32 are also turned off, and the display surface 10 becomes as shown in E of FIG. Then, as the output of the flip-flop 56 becomes H level, the flip-flop 104 and the counter 1
10, 126 are maintained in a reset state. Therefore, the alarm will no longer sound.

(2) Complete stop operation In this case, the user only has to touch the sound stop touch switch 16 indicated by the sound stop touch switch position display 32 on the display screen 10.
As a result, the alarm will stop sounding completely and the display screen 1 will stop sounding completely.
0 switches to the state shown from D to E in FIG.

FIG. 10B is a time chart in this case, and at time t _g in the figure, the chirp touch switch 16 is
If you touch , the flip-flop 56 will be reset and the snooze touch switch 16 will be reset.
As with the third operation, the alarm stops sounding completely, and the position indicators 24 and 32 on the display screen 10
turns off completely. After this, the alarm will no longer sound.

As described above, according to the present invention, by using a touch switch instead of a conventional mechanical switch to operate an alarm, it is possible to reduce costs and facilitate sealing by reducing the number of parts.
Furthermore, by providing the touch switch on the display surface, the display surface can be made wider than when a mechanical switch is used, and if the display surface is the same size, the timepiece device can be made smaller. Also,
By using a transparent electrode for the touch switch, the touch switch does not appear on the display screen when it is not needed, significantly reducing design constraints compared to conventional products. is very preferable.
Furthermore, by providing a touch switch position display that displays the position using an optical display element when the touch switch needs to be operated, the position of the touch switch can be clearly shown on the display screen, and the operation can be done by simply touching the switch. Therefore, very excellent operability can be obtained.
