Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an alarm clock that notifies information regarding the set state of an alarm when the light is turned off.

[Conventional technology]

Generally, in an alarm clock, the alarm is set by a push-type or slide-type silence switch, and whether or not the alarm is set is determined from the state of the silence switch.

[Problem that the invention seeks to solve]

With the above-mentioned conventional system, it was common for people to forget to set their alarms, which led to them oversleeping and being late the next morning.

The present invention prevents the user from forgetting to set the alarm by notifying the user of the set state of the alarm at bedtime.

[Means for solving problems]

In the present invention, the first and second detection circuits detect the turning off of the light, and at this time, the discrimination circuit determines whether or not an alarm is set, and the information regarding the alarm setting state is notified. It is structured as follows.

〔Example〕

In Figure 1, 1 is an oscillator, 2 is a frequency divider, 3
is a drive circuit for a motor 4, and the motor 4 is used to advance a time display hand (not shown). Reference numeral 5 denotes a sound generation circuit which generates a message such as "Are you sure you want to set the alarm?" when the alarm is not set. 6 is an alarm circuit, 7 is a sounding device, 8 and 9 are gate circuits, and 10 is an inverter. 11 is a phototransistor, 12 is a resistor, and 13 is a differential circuit, which allow the first
It constitutes a detection circuit. 14 is a level detection circuit, 15 is a timer circuit set to, for example, 10 seconds,
These constitute a second detection circuit. 16 is an alarm set switch, and 17 is an alarm switch. 18 is a one shot circuit, and 19 is a light emitting device.

In the above configuration, the phototransistor 11 is turned on when the surroundings are bright. Generally, people turn on the lights before going to bed, and then turn them off and go to bed. So, when I forgot to set the alarm and tried to sleep with the alarm set switch open, I turned off the light, and the phototransistor 1
1 suddenly changes from on to off and the differentiation circuit 13
A differential pulse is generated from The timer circuit 15 is activated by this differential pulse, and a pulse is generated after 10 seconds. On the other hand, the level detection circuit 14 generates an output when the surrounding area is dark beyond a certain level, and when this output and the pulse from the timer circuit 15 occur simultaneously, it is assumed that the light is turned off. for example,
When a person crosses in front of this clock device and enters the shadow,
Because it suddenly becomes dark, a pulse is generated from the differentiating circuit 13, but in this case, the dark time is instantaneous, and when the pulse is generated from the timer circuit 15 10 seconds later, it has already become bright and the level detection circuit 14 No output is occurring. Therefore, in such a case, the light is not considered to be off, but only when it is dark even 10 seconds after the differential pulse is generated.

Since the alarm set switch 16 is now open, the gate circuit 8 is opened by the output of the inverter 10, and the pulse from the timer circuit 15 is supplied to the audio generation circuit 5. As a result, a message is read out from the voice generation circuit 5, and the sound generation device 7 emits a voice saying "Are you sure you want to set the alarm?"

On the other hand, in response to the pulse from the gate circuit 8, a pulse having a width of, for example, about 10 seconds is generated from the one shot circuit 18, and the light emitting device 19 is turned on. The light emitting device 19 is provided near an operating member (not shown) of the alarm set switch 16, so that the operating member can be located even after the light is turned off, and the alarm can be easily set.

Note that if the alarm set switch 16 is closed and an alarm has already been set before the lights go out, the differential pulse caused by the lights out is cut off by the gate circuit 8, and the above-mentioned sound is not generated.

When the alarm switch 17 is closed the next morning with the alarm set, an output is generated from the gate circuit 9, an alarm signal is generated from the alarm circuit 6, and an alarm sound is generated from the sound generating device 7.

Incidentally, although the brightness of the surroundings changes frequently, even if the brightness changes from bright to dark, if the change is gradual, the differentiating circuit 13 does not generate a pulse. in general,
In daily life, the only time there is a sudden change from bright to dark is when the lights are turned off, so there is very little risk of sound occurring when it is not needed.

Figure 2 shows a system that generates a sound to notify the user even if an alarm has been set when the lights are turned off.The configuration is such that gate circuits 20 and 21 and a sound generation circuit 22 are added to Figure 1. This is what I did.

In the above configuration, when the alarm is set, the gate circuit 20 is open, and when the light is turned off and a pulse is generated from the gate circuit 21 in the same manner as above, this is supplied to the sound generation circuit 22. . The sound generation circuit 22 outputs, for example, "Good night" or "Alarm set OK".
A message like this will appear.

Note that each of the above embodiments can also be applied to an all-electronic timepiece.

FIG. 3 shows the case where it is used in an all-electronic clock, and if an alarm is set when the lights are turned off, a voice will notify you how many hours later the alarm will sound. In the figure, 23 is an oscillator, 24 is a frequency divider, 25 is a current time clock circuit, and 26 is an alarm time setting circuit. 27 is a coincidence circuit, 28 is a latch circuit, and 29 is an arithmetic circuit that calculates the time difference between the current time and the alarm time. Reference numerals 30 and 31 are voice generating circuits, and the voice generating circuit 30 sends a message indicating non-setting such as "Are you sure you want to set?" to the voice generating circuit 31.
In response to the output from the arithmetic circuit 29, a message saying ``We will notify you in ○ hours and ○ minutes'' is generated.

The same numbers as in FIG. 2 indicate the same parts.

In the above configuration, if the alarm is not set when the light is turned off, the voice generating circuit 30 will ask "Are you sure you want to set it?" as in the above example.
A message will appear. To explain the operation when the alarm is set, the output of the current time is latched in the latch circuit 28 by the pulse from the gate circuit 21 when the light is turned off, and the time difference from the alarm time is calculated by the calculation circuit 29. Ru. The above-mentioned pulse from the gate circuit 21 is supplied to the sound generation circuit 31 via the gate circuit 20. For example, if the above-mentioned time difference is 6 hours and 40 minutes, a message saying "I will notify you in 6 hours and 40 minutes" is generated. . This allows you to know how much sleep you have.

In this case, the output of the alarm time setting circuit 26 may be directly supplied to the voice generating circuit to notify the alarm time, ``I will notify you at XX o'clock XX minutes''.

It goes without saying that the message content in each of the above embodiments is not limited to this.

[Effects] According to the present invention, if it is dark intermittently for a certain period of time or more, it is assumed that the light is off, and at this time it is determined whether or not an alarm has been set, and a notification to that effect is given. It is possible to know whether or not it has been set without performing any operations, and it is possible to prevent forgetting to set it.

Moreover, since the light is not considered to be off just because it becomes dark momentarily, there is no malfunction and it is possible to reliably detect that the light is off.

Furthermore, by lighting the light emitting element for a certain period of time when it is determined that the clock is not set, it is possible to know the whereabouts of the clock even in the dark after the light is turned off, and it is possible to easily set an alarm.
