Description

[Detailed Description of the Invention] (a) Field of Industrial Application The present invention relates to a watch with a snooze function, and particularly to one that changes the volume of a notification sound when a set time such as on the hour is reached during the snooze operation.

(b) Prior art As a conventional clock of this kind, the
There is one shown in Publication No. 24670.

In general watches with a snooze function, including this watch, when the snooze switch is operated while the alarm is sounding, the alarm stops temporarily and then sounds again after a fixed period of time.

The watch repeats this operation until the ringing switch is turned off.

(c) Problems to be solved by the invention In the above conventional example, if the snooze operation, that is, the alarm sound stops for a certain period of time when the snooze switch is operated, and then starts again, is repeated many times, the alarm setting time Time passes because of this.

For this reason, users often set an alarm time earlier than the actual wake-up time so that they wake up closer to the actual wake-up time.
For example, if you have to wake up at 7 a.m., set the alarm time to 6:50 a.m. After the alarm starts at this time, snooze several times and wake up when the time approaches 7 a.m. This is the case.

In this case, it is necessary to calculate before going to bed how many minutes earlier the alarm time should be set than the actual time to wake up, and also to some extent the number of snooze operations after the alarm notification starts. If you wake up at the desired time, you may not be able to wake up at the desired time, and even if you count the number of snooze operations, the interval between the notification sound and the snooze switch operation will be different each time, so you may not be able to wake up at the exact time you want. The problem was that I couldn't wake up.

(d) Means for solving the problem The purpose of the present invention is to enable the user to know the approximate time when he or she actually has to wake up, even if the alarm time is set early, so that the user can wake up at the desired time immediately. To provide a clock with a snooze function that allows you to wake up in the morning.

The present invention has a snooze function that includes a notification circuit that outputs a notification signal when a match signal output from a reference circuit is input at the alarm time, and a sound generation circuit that generates a notification sound when this notification signal is output. The timepiece is characterized in that a volume variable circuit is connected between the notification circuit and the sound generation circuit, and increases the volume of the subsequent notification sound when a fixed time signal from the time display section is input.

The detailed circuit of the above-mentioned volume variable circuit 46 is explained in the second section.
It is configured as shown in the figure.

The FF 50 inputs the output signal B from the OSM 25 in the notification circuit 22 to a set input S, and inputs fixed time signals φ ₅ and φ ₆ to a reset input R via an OR gate 52.

The AND gate 54 inputs the clock signal φ ₁ and the clock signals φ ₂ and φ ₃ and outputs a signal L.

is input and signal M is output.

AND gates 58 and 60 are opened and closed by notification signal H, and AND gate 58 is opened and closed by notification signal H.
Input signal L from the output of FF50 and input signal N
and the AND gate 60 outputs the notification signal H.
The signal from the output Q of the FF 50 and the signal M are input, and the signal O is output.

The OR gate 62 inputs these signals N and O,
A variable volume notification signal K is output.

The signal L outputted by the AND gate 54 is a composite of signals φ ₁ , φ ₂ , and φ ₃ as shown in FIG. 4, and is composed of pulses with a duty cycle of 50%.

Furthermore, the signal M output by the AND gate 56 is
This signal L is synthesized with the signal _φ4 shown in FIG. 4, and is composed of pulses with a duty cycle of 25%.

When this signal M is generated as a signal K via an AND gate 60 and an OR gate 62, an alarm sound of a normal volume is generated from the sound generation circuit 48, and a signal L is generated as a signal K via an AND gate 58 and an OR gate 62. A high-volume alarm will then sound.

Next, the operation of the circuit shown in FIGS. 1 and 2 will be explained using the time charts shown in FIGS. 3 to 5.

Now, when the alarm time arrives, the matching circuit 18 outputs the count contents of the time counter 8 and the alarm memory 1.
It is detected that the stored contents of No. 6 match, and the output signal is set to H level.

If the ring stop switch 23 is in the on state at this time, the AND gate 20 outputs the detection signal A
becomes H level.

When this detection signal A becomes H level, the OSM 25 generates a pulse in its output signal B in response to its rising edge.

This pulse is applied to FF32, 34 and FF50 (second
) is applied to each set input S of these FFs.
Set 32, 34, 50.

When the FFs 32 and 34 are set, their output signals D and E go to H level, and the AND gate 36 inputting these signals D and E becomes open, and the output signal H goes to H level.

Therefore, the AND gate 60 which inputs this H level signal H and the H level signal from the set output Q of the FF 50 is in an open state, and the output signal O of this AND gate 60 is connected to the AND gate 56.
An output signal M is generated.

The signal O generated by this signal M is generated by the OR gate 6
2, a signal K is generated and applied to the sound generation circuit 48.

At this time, signal K has a duty cycle.
Since the signal M consisting of 25% pulses is generated, the sound generation circuit 48 intermittently generates an alarm sound at a normal volume.

When the snooze switch 38 is turned on, an operation pulse is generated in its output signal G, and this operation pulse is applied to the FF 32 and the reset input R of the timer 44 to reset them.
When FF32 is reset, its output signal D becomes L.
level, the AND gate 36 is closed, and its output signal H becomes L level. This signal H
When the signal becomes the L level, the AND gate 60 in the volume variable circuit 46 is closed, and its output signal O is kept at the L level, so that the output signal K of the OR gate 62 also becomes the L level.

Therefore, the sound generation circuit 48 stops generating the alarm sound.

At this time, the timer 44, which has been reset by the operation pulse generated in the signal G, starts counting and, after counting for a certain period of time, generates a pulse in the signal I from its output C.

This pulse is applied to the set input R of the FF 32, putting the FF 32 into the set state again.

Therefore, the AND gate 36 is opened again, its output signal H becomes H level, and the alarm sound is generated again in the same manner as described above.
While repeating such a snooze operation, when the time reaches the hour such as 7 o'clock, a pulse is generated in the fixed time signal φ ₆ from the time counter 8.

This pulse is applied to the reset input R of the FF 50 via the OR gate 52 in the volume variable circuit 46 to reset it.

Therefore, the output Q of FF50 is L, respectively.
The signal is switched to H level, and the AND gate 58 to which the signal from the output is input is opened.

Therefore, the output signal N of this AND gate 58
A signal L is generated at the output signal K, and a signal L is also generated at the output signal K via the OR gate 62.

Therefore, the signal K including the signal L consisting of pulses with a duty cycle of 50% is applied to the sound generation circuit 48, and an alarm sound having a higher volume than the normal volume is generated.

When a pulse is generated in the fixed time signal φ ₅ or φ ₆ in this manner, a high-volume alarm sound is generated each time the snooze operation is repeated after the pulse is generated.

Incidentally, when the ring stop switch 23 is turned off, the AND gate 20 in the reference circuit 14 is closed, and its output signal A becomes L level.

The OSM 26 generates a pulse in its output signal C in response to the rising edge of the signal A inverted by the inverter 24.

As a result, the FFs 32 and 34 that input this pulse to the reset input R are reset, the AND gate 36 is closed, and the snooze counter 40 is kept in the reset state due to the signal F going to the H level, and the alarm notification ends. do.

Furthermore, in this embodiment, the volume of the alarm sound is set to change at the hour or half-hour; however, when setting an alarm sound, the standard is often at the hour or half-hour. It's for a reason.

(f) Effect of the invention According to the invention, even if the alarm setting time is set earlier than the desired wake-up time, the user can confirm that it is time to wake up by the volume level of the alarm sound. This eliminates the need to calculate how early to set the alarm, or to estimate the approximate time by counting the number of snooze operations.
