Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a snooze alarm clock.

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

[Problems to be Solved by the Invention] Since the alarm switch operates every 12 hours, for example, if you want the alarm to sound at 7 a.m., it is necessary to set the alarm after 7 p.m. As a result, people often forgot to set the alarm and the alarm did not sound the next morning.

Furthermore, in general, an alarm sound is often sounded at a fixed time every day on weekdays, and the alarm must be set every night, which is troublesome.

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 the Problems] The present invention provides a snooze switch that temporarily stops the alarm sound and then starts it again, and operates the snooze switch every 12 hours by predetermined operation of the snooze switch. This system is equipped with a prohibition circuit that prohibits the generation of an alarm sound due to the next operation of the alarm switch.

[Example] In the drawing, 1 is an alarm switch that operates every 12 hours, 2 is an alarm set switch, and 3 is an alarm switch that operates every 12 hours.
is a snooze switch. 4 is a timer for 13 to 23 hours, 5 is a 10 second timer for counting the operating time of the snooze switch 3, and 6 is a 5 minute timer for snooze forming a control circuit. 7 is an alarm set confirmation sound generation circuit, 8 is an alarm generation circuit, 9-
15 is a flip-flop circuit, 16 to 23 are gate circuits, and 24 and 25 are inverters. In the above configuration, the timer 5, flip-flop circuits 11-13, and gate circuits 18 and 19 constitute a prohibition 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 the reset state.

When the desired time comes and the alarm switch 1 closes, the D input of the flip-flop circuit 9 becomes "1" due to the output from the gate circuit 16.
A 16Hz clock pulse from terminal a causes its output to fall to "0". Therefore, one pulse with a narrow width is generated from the gate circuit 17, and the timer 4 and flip-flop circuits 14 and 15 are reset.

On the other hand, as the output of the flip-flop circuit 9 falls, the output Q of the flip-flop circuit 10 is inverted to "1", and the output of the gate circuit 23 becomes "1".
, the alarm generation circuit 8 operates and an alarm sound is generated.

Therefore, when the switch 3 is closed once and then opened again, 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 is inverted to "1" and the output is "0'' and the timer 6 starts counting. 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 is closed, and the alarm sound stops.

When five minutes elapse and an output is generated from the timer 6, the flip-flop circuits 12 and 13 are reset, the output of the gate circuit 19 is inverted to "1", and the alarm sound begins to sound again.

In this manner, a snooze operation is performed each 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", and the flip-flop circuit 10
is reset and the sound is stopped.

If the ringing 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 then 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 output Q of the flip-flop circuit 13 is inverted to "1".
0 is reset. On the other hand, the outputs Q of the flip-flop circuits 11, 14, and 15 are held at "0", and the output of the gate circuit 22 is held at "0". Therefore, even if the alarm switch 1 is closed next, the output of the gate circuit 16 will be "0".
remains in place, and no alarm sound is generated.

After that, i.e. from the occurrence of the above alarm sound
After 13 to 23 hours have passed, the output of timer 4 becomes “0”
When the flip-flop circuit 14 is inverted, 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 every 24 hours without having to set the alarm.

By the way, in order to cancel the 24-hour alarm and make it similar to a normal alarm clock, the snooze switch 3 must be closed for at least 10 seconds. As a result, the reset of the timer 5 is released, and an output is generated after 10 seconds, triggering the flip-flop circuit 11, and its output Q becomes "1", which becomes the output "1" of the gate circuit 22, and the gate circuit 16 opens. 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 the alarm is activated every 24 hours.

In addition, as the output Q of the flip-flop circuit 11 is inverted, that is, as the alarm is switched between the 24-hour alarm and the normal alarm, a specific confirmation sound is generated from the alarm set confirmation sound generation circuit 7.
You will be notified that the switching has taken place.

Further, when the set switch 2 is closed to set the alarm, the alarm set confirmation sound generating circuit 7 is operated, and a confirmation sound different from the above is generated to notify that the alarm has been set.

[Effects of the Invention] According to the present invention, the alarm can be switched to every 24 hours by operating the snooze switch again after setting snooze.
You can set an alarm every 24 hours without adding a new switch, and you can set an alarm for the next morning without having to set it the night before. Therefore, it is possible to avoid forgetting to set an alarm, and to prevent being late.
Moreover, by continuously operating the snooze switch for a predetermined period of time or more, the 24-hour alarm can be returned to a normal alarm, and even if the snooze switch is operated incorrectly, the desired state can be restored.
