Description

[Detailed explanation of the idea] The present invention relates to an electronic watch equipped with an alarm warning device.

In a conventional electronic watch equipped with a daily alarm warning device, an alarm stop switch and an alarm set release switch are configured as separate operation switches.

Therefore, if you use this electronic watch with an alarm as a one-time alarm, such as setting it for 2:00 a.m. to meet someone at 3:00 a.m., the alarm will not sound again after you have turned off the alarm. Therefore, it was necessary to operate a separate operation switch to cancel the alarm set.

Moreover, if a different alarm time was not set until the next day, there was a problem in that the alarm would sound again at 2:03 a.m. the next day.

Therefore, in the present invention, considering the above points, an electronic watch equipped with a daily alarm warning device is provided with one operation switch and a control circuit, and the function of the control circuit is controlled by changing the operation method of the operation switch. An electronic clock characterized in that the operation switch is configured as an operation switch that serves as both an alarm stop switch and an alarm set release switch, and when the operation switch is opened and closed once within a certain period of time, the alarm stops sounding. It is an object of the present invention to provide an electronic timepiece in which the control circuit functions as an alarm set release switch when the switch is opened and closed twice.

This will be explained below with reference to the drawings.

FIG. 1 is a block circuit diagram of an embodiment of an electronic timepiece according to the present invention.

2 is a reference signal generator, 4 is a frequency dividing circuit, 6 is a timing circuit, 8
10 is a display decoder drive circuit, 10 is a display device, 12 is an alarm setting storage circuit, 14 is an alarm setting operation switch, 16 is an alarm coincidence detection circuit, 18 is an alarm coincidence storage circuit, 20 is an alarm alarm device, and 22 is an alarm sounding circuit. An operation switch 24 for stopping and canceling the alarm set is a first control circuit.

When the time held in the clock circuit 6 reaches the time set in the alarm setting storage circuit 12, the coincidence detection circuit 16 detects it and the line 26 changes from L to H, and the alarm coincidence storage circuit 1
The output line 30 of the flip-flop 28 of No. 8 changes from L to H and is fixed, and the alarm warning device 20 issues an alarm.

When the line 30 becomes H, the AND gate 32 opens, and the φ3 signal is transmitted from the frequency divider circuit 4 to the timer counter 34, and the signal is approximately 1
After a minute, the output line 36 goes from L to H, which resets the flip-flop 28 through the reor gate 38 and changes the line 30 from H to L.

At this time, the timer counter 34 is also reset.

In short, the alarm warning device is configured to automatically stop sounding in about one minute.

Furthermore, when the operation switch 22 is opened or closed while the alarm warning device 20 is sounding, this opening/closing signal is sent to the first control circuit 2 via the flip-flop 40 for eliminating chattering.
4 changes the output of the flip-flop 44.
Fix it to.

When the line 46 changes from L to H, the flip-flop 28 is reset via the OR gate 38 and the alarm stops sounding.
When the line 46 is H, the AND gate 50 is opened via the OR gate 48, and the φ2 signal is transmitted to the timer counter 52, which changes the output line 54 from L to H after about 3 seconds.
Flip-flop 44.56 and timer counter 5
Reset 2.

If the operation switch 22 is opened and closed again before the flip-flop 44 is reset while the output line 46 is in the H level, the output line 58 of the flip-flop 56 changes from L to H level, and at this time the alarm setting storage circuit 12 is Reset to zero and cancel the alarm set.

At this time as well, the AND gate 50 is opened via the OR gate 48, so the flip-flops 44 and 56 are reset.

In summary, when the line 30 is H and the alarm is sounding, opening and closing the operating switch 22 once within about 3 seconds will stop the alarm from sounding, and opening and closing the switch twice will cancel the alarm setting. .

Therefore, in this watch, if the alarm time set in the alarm setting memory circuit 12 is only for one time, it is only necessary to open and close the operating switch 22 twice in succession when the alarm stops sounding, and the alarm will be set again the next day. If you want to sound the alarm at the specified time, all you have to do is open and close the operation switch 22 once to stop the alarm from sounding.

FIG. 2 is also a partial circuit block diagram of an embodiment of the electronic timepiece according to the present invention.

The drawing is basically based on FIG. 1 and like numbers indicate like contents.

Here, a second control circuit 60 for setting/unsetting the alarm is provided after the alarm coincidence detection circuit 16, and when the operation switch 22 is opened and closed twice as explained in FIG. 1, the line 58 changes from L to H. At the same time, the output line 64 of the flip-flop 62 of the second control circuit 60 is fixed from L to H, and the line 70 becomes L via the inverter 66, and the AND gate 68 is closed.

Therefore, at this time, even if an alarm coincidence signal is transmitted via the line 26, it will be cut off, and the alarm will be in the unset state.

When the operation switch 14 is operated to set a new alarm setting time, the flip-flop 62 is reset via the line 72 and the line 70 becomes H, opening the AND gate 68, so this operation returns the alarm to the set state. ing.

By photoelectrically displaying changes in the line 70, the set and unset states can be seen at a glance.

In the case of mechanical alarms, the alarm setting time always indicates the existence time of one of them, so in such a case, if the second control circuit 60 in FIG. 2 is used,
Alarms can be easily set and canceled.

As described above, the electronic timepiece according to the present invention is capable of stopping the ringing and canceling the alarm setting with a single operation switch, making it easy and extremely convenient to switch between the daily alarm and the temporary alarm.

In addition, as an example of the operation switch 22 and the first control circuit 24 which are used to silence the alarm and cancel the alarm setting, an example is shown in which the cancellation of the alarm setting is distributed depending on the number of times the operation switch is pressed. Another possible method is to distribute the information.
