Abstract

PURPOSE:To set an alarm at every 24hr without adding newly a switch, by switching to an alarm of every 24hr by a prescribed operation of a snooze switch. CONSTITUTION:When a snooze is set by a snooze switch 3, and thereafter, the snooze switch 3 is closed again, an alarm of every 24hr is set. That is to say, by a second operation of the snooze switch 3, an output Q of a FF 13 is inverted to '1', and n FF 10 is reset. On the other hand, outputs Q of FFs 11, 14 and 15 are held in '0', and an output of a gate circuit 22 is held in '0'. In this state, when 13-23hr elapse from the generation of alarm sound and an output Q' of a timer 4 is inverted to '0', the output Q of the FF 14 becomes '1'. Accordingly, when an alarm switch 1 operates in the next time, the alarm sound is generated.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a snooze alarm clock.

[Prior Art] In a conventional analog alarm clock, an alarm switch is configured to operate every 12 hours.

[Problem to be Solved by the Invention 1] Since the alarm switch operates every 12 hours, for example, if you wanted the alarm to sound at 7 a.m., you had to set the alarm after 7 p.m. Therefore,
I often forgot to set my alarm and the alarm didn't go off the next morning.

Furthermore, in general, an alarm tone often sounds at a fixed time every day on weekdays, and the alarm has to be set every night, which is cumbersome.

SUMMARY OF THE INVENTION An object of the present invention is to provide a snooze alarm clock that can selectively sound an alarm every 24 hours without adding a new switch.

Means for Solving Problem C] The present invention provides an alarm that is provided with a snooze switch for temporarily stopping the alarm sound and then making it start again. A prohibition circuit is provided to prohibit the generation of an alarm sound due to the next activation of the switch.

[Example] In the drawings, 1 is an alarm switch that operates every 12 hours, 2 is an alarm set switch, and 3 is a snooze switch. 4 is a 13-23 hour timer, 5 is a 10 second timer that measures the operating time of the snooze switch 3,
6 is a 5-minute timer for snooze, which constitutes a control circuit. 7 is an alarm set confirmation sound generation circuit, 8 is an alarm generation circuit, 9 to 15 are flip-flop circuits, 16 to 2
3 is a gate circuit, and 24.25 is an inverter.

In the above configuration, timer 5. Flip-flop circuits 11 to 13 and gate circuits 18 and 19 constitute an inhibition circuit.

Next, the operation will be explained. It is assumed that the set switch 2 is now closed and the flip-flop circuits 9 to 13 are in a reset state.

When the desired time comes and the alarm switch 1 is closed, the D input of the flip-flop circuit 9 becomes 11" due to the output from the gate circuit IB, and the 16Hz from terminal a becomes
The output (2) falls to "0" by the clock pulse of (2). Therefore, one narrow pulse is generated from the gate circuit 17, and the timer 4 and flip-flop circuits 14 and 15
is reset.

On the other hand, due to the fall of the output enable of the flip-flop circuit 9, the output Q of the flip-flop circuit 10 is inverted to "1", the output of the gate circuit 23 becomes "1", and the alarm generation circuit 8 is activated to generate an alarm sound. occurs.

Therefore, when the switch 3 is closed and then reopened, one pulse is generated from the gate circuit 18, and the fall of the pulse triggers the flip-flop circuit 12, and its output Q becomes "
At the same time, the output enable signal is inverted to "0" and the timer 6 starts counting time.

When the pulse from the gate circuit 18 and the output Q of the flip-flop circuit 12 become "1", the output of the gate circuit 19 becomes "0", the gate circuit 23 closes, and the alarm sound stops.

Then, when 5 minutes have elapsed and an output is generated from timer 6,
The flip-flop circuits 12 and 13 are reset, the output of the gate circuit 19 is inverted to mI#, and the alarm sound starts to sound again.

In this way, a snooze operation is performed every time the snooze switch 3 is closed.

To completely stop the alarm sound, open the switch 2, which causes the output of the inverter 25 to become "1".
, the flip-flop circuit 10 is reset and the sound is stopped.

Note that if the alarm sounding operation is not performed, an output is generated from the terminal F of the timer 4 after several minutes, the flip-flop circuit 10 is reset, and the alarm sound is automatically stopped.

By the way, when the snooze switch 3 is set to snooze and the snooze switch 3 is closed again, an alarm every 24 hours is set. That is, by operating the snooze switch 3 for the second time, the output Q of the flip-flop circuit 13 is inverted to "1", and the flip-flop circuit 10 is reset. On the other hand, the output Q of the flip-flop circuits 11, 14.15 is MO''
, and the output of the gate circuit 22 is held at "O". Therefore, even when the alarm switch 1 is closed next time, the output of the gate circuit 16 remains at "0" and no alarm sound is generated.

After that, i.e. 13-2 days from the generation of the above alarm sound.
When three hours have passed and the output amount of the timer 4 is inverted to "O", the output Q of the flip-flop circuit 14 becomes "1". Therefore, when the alarm switch 1 is operated next, the same operation as described above is performed and an alarm sound is generated.

In this way, by closing the snooze switch 3 again during snooze, the alarm sound will sound 24 hours later even if the alarm is not set.

By the way, to cancel the 24-hour alarm and use it like a normal alarm clock, set the snooze switch 3 to 1.
It is to be kept closed for 0 seconds or more.

This releases the reset of the timer 5, and 10 seconds later, an output is generated and the flip-flop circuit 11 is triggered, its output Q becomes "1", the output of the gate circuit 22 becomes "1#", and the gate circuit 16 is opened.Therefore, if the switch 2 is closed and the alarm is set, an alarm sound will be generated each time the alarm switch 1 is closed, making it similar to a normal alarm clock.

If the snooze switch 3 is held down again for 10 seconds or more, the flip-flop circuit 11 is inverted again, and this time an alarm occurs every 24 hours.

In addition, as the output Q of the flip-flop circuit 11 is inverted, that is, when switching between the alarm every 24 hours and the normal alarm, the alarm set confirmation sound generation circuit 7 is activated.
A specific confirmation sound is generated to notify that the switch has been made.

Furthermore, when the set switch 2 is closed to set the alarm, the alarm set confirmation sound generation circuit 7 is activated.
A confirmation sound different from the above is generated to notify the alarm set.

[Effects of the Invention] According to the present invention, the alarm can be set every 24 hours by a predetermined operation of the snooze switch, so the alarm can be set every 24 hours without adding a new switch. You can set an alarm for the next morning without having to set an alarm for the next morning. Therefore, it is possible to avoid forgetting to set an alarm, and it is possible to prevent being late.
