Description

[Detailed description of the invention] The present invention relates to an alarm electronic timepiece.

In the conventional method, when an alarm is set and the alarm is sounded and the alarm is stopped, the user often unconsciously presses the stop switch when the alarm sounds in the morning and goes back to sleep.

Therefore, in the present invention, an electronic watch with an alarm includes a first counter circuit that stores a setting value corresponding to the operation setting of the switch, and a second counter circuit that counts the operation time of the alarm cut-off switch or the snooze switch. a coincidence detection circuit that compares and detects the memory content of the counter circuit and the memory content of the first counter circuit, and when the count content matches the memory content, a coincidence detection signal output from the coincidence detection circuit, It is an object of the present invention to solve the above-mentioned problems by providing an electronic timepiece with an alarm, which is characterized in that the alarm is configured to stop ringing or stop ringing.

This will be explained below with reference to the drawings.

FIG. 1 shows an example of an electronic watch with an alarm according to the present invention.
It is a circuit diagram of the block.

2 is a reference signal generation source, 4 is a frequency dividing circuit, 6 is a timing circuit, 8
1 is an alarm setting time storage circuit, 10 is an alarm coincidence detection circuit, 12 is an alarm coincidence storage circuit, 14 is an alarm warning device, 16 is a photoelectric display device, 18 is an operation switch, 2
0 is a control circuit.

When the time held by the clock circuit 6 reaches the alarm setting time storage circuit 8, it is detected by the coincidence detection circuit 10, and the output line 22 goes low.
becomes H.

As a result, the output line 26 of the flip-flop 24 of the alarm coincidence storage circuit 12 becomes H and is fixed at the H state.

As a result, the alarm warning device 14 continues to notify the alarm warning.

Further, the holding time signal a and the alarm setting time signal b of the clock circuit 6 are transmitted to the photoelectric display device 16 and displayed on the display body A and the display body B, respectively.

By the way, you can stop this alarm from sounding by pressing the operation switch 18.
Let's do it.

When a predetermined time is set in the alarm setting time memory circuit 8 (the operating switch for setting is not shown), if this operating switch 18 is closed and held as it is, the output line 40 of the flip-flop 28 for chattering removal becomes H. Become.

At this time, since no alarm is reported, the line 26 is L, and the line 34 is H via the inverter 32.
AND gate 38 is closed.

On the other hand, the AND gate 36 is opened because the lines 40 and 34 are H, and the 1Hz signal transmitted from the frequency divider circuit 4 via the line 35 is
A signal is sent from the output line 42 of the AND gate 36 to the first counter circuit 44 and to the flip-flops 46, 48.
, 50, 52.

In this case, when the operation switch 18 is closed and held for 15 seconds, the flip-flops 46, 4
8, 50, 52, respectively output lines 54, 56, 58,
60 becomes L, the output line 64 of the NAND gate 62 becomes L, and the AND gate 66 closes.Even if the AND gate 66 is opened or closed further, the contents stored in the first counter circuit 44 do not change.

In any case, the number of pulses of the signal transmitted from the frequency dividing circuit 4 is stored in the counter circuit 44 in proportion to the holding time of the operation switch 18.

When the alarm alarm is reported, the line 26 is H, so the AND gate 36 of the switching gate 30 is closed. The 1/8 Hz signal transmitted by
It is counted as 2, 74, 76, 78.

When the counted contents match the stored contents of the first counter circuit 44, the output line 84 of the AND gate 82 of the coincidence detection circuit 80 changes from L to H, the flip-flop 24 of the alarm coincidence storage circuit 12 is reset, and the line 26 changes from L to H. H to L
, and the alarm notification by the alarm warning device 14 is stopped.

In short, in order to stop the alarm by operating the operation switch 18, the operation switch 18 must be operated until the count value of the second counter circuit 68 matches the specific value set and stored in the first counter circuit 44. It is necessary to continue holding 18 operations.

Therefore, depending on the situation, for example, when the user is tired and is unlikely to wake up, the user increases the operation value preset and stored in the first counter circuit 44, and the alarm sounds. To stop the alarm from ringing,
It is possible to prevent the alarm from sounding even if the operating switch 18 is held and operated a little unconsciously.

While the user consciously tries to hold down the operation switch 18 in order to stop the alarm from sounding, the user also wakes up.

Note that when the line 84 becomes H, the flip-flops 46 , 48 , 50 , 52 of the first counter circuit 44 are reset, the lines 54 , 56 , 58 , 60 become L, and the output line 88 of the gate 86 becomes H. The output line 54 becomes H, and the first counter circuit 4
1 is stored in 4.

In short, numbers from 1 to 15 are always set and stored in the first counter circuit 44, and the numerical signal C of this set value is transmitted to the display device 16 and displayed on the display C.

Further, when the line 84 becomes H, the flip-flops 72, 74, 76, and 78 of the second counter circuit 68 are reset.

With this configuration, the operating switch 18 can be held for at least 8 seconds to stop the alarm from sounding, but at most it must be held for 2 minutes.

Here, although the same operation switch 18 is used, the first
In order to set the value to the counter circuit 44 in a short time, a 1 Hz signal is transmitted to the AND gate 36 and a 178 Hz signal is transmitted to the AND gate 38, so that the transmitted signals can be distinguished. ing.

Here, if the transmission line 35 from the frequency dividing circuit 4 is removed,
The signal indicating the number of openings and closings of the operation switch 18 is transmitted as it is to the first counter circuit 44 via the AND gate 36, and such a configuration can also be used as a method for setting a specific value to the first counter circuit 44. I can think.

Note that the embodiment shown in FIG. 1 is just one example, and the range in which the number of operations can be set can be increased or decreased.
Further, the setting of the value to the first counter circuit 44 can be configured such that when the NAND gate 62 is removed and the value is set too high, the value is set again from 1.

Furthermore, in order to disconnect the wire 84 from being connected to the reset terminal of the first counter circuit 44 with such a configuration, it is necessary to set an arbitrary value to the first counter circuit 44 once. For example, unless you change the value, you can use it every time you set an alarm without having to set it repeatedly.

Further, this operation switch 18 is connected to the first counter circuit 44.
Although the first switch for setting and storing the value and the ring stop switch are also used, separate operation switches may be used.

Further, although the operation switch 18 is used here as a ring stop switch, it may also be used as a snooze switch.

As described above, the electronic watch with an alarm according to the present invention is designed to allow the user to wake up according to the situation by adjusting the sound time when notifying the alarm to a longer or shorter time or adjusting the alarm volume to a higher or lower value. Even compared to what is coming, rather than relying on passive motives from the user's point of view, such as the length and size of the sound, the alarm will not stop sounding unless the user takes a fixed action. This is a system that ensures that this happens through active involvement, and is highly effective given its novel concept and ease of use.
