Description

[Detailed Description of the Invention] The present invention relates to an improvement in a watch with a snooze function, particularly one in which the snooze time can be set in accordance with the operation time of the snooze switch.

Conventional snooze watches stop the alarm sound by operating the snooze switch when the alarm sound is sounded at the alarm set time, and the alarm sound is emitted again after a certain snooze time has elapsed due to the operation of the snooze mechanism. It was widely used in alarm clocks, etc.

However, in conventional snooze watches, the snooze time from when the alarm sound is once stopped until the alarm sound is started again is set to a fixed time, and the degree of freedom in operating the snooze mechanism is low. For this reason, there are many requests from users for a snooze mechanism that allows them to freely set the snooze time, and devices that meet this request have recently been proposed. For example, the snooze time can be set in accordance with the operating time of the snooze switch, and this proposal has the effect of allowing the snooze time to be freely set each time the snooze function is operated.

However, in the above proposal, when the snooze time is set by operating the snooze switch, the snooze time is set only by the user's intuition. As a result, users are unable to know the exact snooze time, and end up feeling uneasy about whether the snooze time they have set is appropriate or not, and may actually set an inappropriate snooze time. The downside is that it can sometimes cause problems.

The present invention was devised in view of the above-mentioned conventional problems.The purpose of the present invention is to provide a snooze switch that can accurately recognize the set snooze time in a device that allows the snooze time to be set in accordance with the operating time of the snooze switch. Our goal is to provide watches.

In order to achieve the above object, the present invention is characterized in that when setting the snooze time by operating the snooze switch, a snooze time confirmation sound, which is an intermittent sound corresponding to the snooze time setting, is emitted. .

Embodiments of the present invention will be described below based on the drawings.

FIG. 1 is a block diagram showing an embodiment of a snooze watch to which the present invention is applied, and FIG. 2 is a time chart showing its operation.

A clock circuit 2 having an alarm mechanism that outputs an alarm start signal that continues for about 20 minutes at an alarm setting time has a well-known configuration, and an output 2a from which the alarm start signal is generated is supplied to an AND gate 4. The output 6a of the ring stop switch 6 is also supplied to the AND gate 4, and the output 4a of the AND gate 4 is supplied to an AND gate 8 constituting an alarm signal generation circuit. This AND gate 8 is also supplied with an output 2b that generates a 2048Hz signal from the frequency divider in the clock circuit 2, and the AND gate 8
An alarm signal as shown in FIG. 2 is generated at the output 8a. This alarm signal is then supplied via the OR gate 10 to a sound generation circuit 16 composed of an amplifier 12 and a speaker 14, and the sound generation circuit 16 generates an alarm sound "beep".

An output 18a of the snooze switch 18 is supplied to an AND gate 20, which is also supplied with an output 4a. Therefore, the operation of the snooze switch 18 becomes effective when an "H" level signal is generated at the output 4a. and output 20a
is supplied to a set terminal S of a flip-flop (hereinafter referred to as FF) 22, and the output of FF 22 is supplied to an AND gate 8. Therefore, when the alarm setting time arrives, an alarm sound is generated from the sound generation circuit 16, and if the snooze switch 18 is operated after this, the output of the FF 22 becomes "L" level, so the generation of the alarm signal stops and the alarm is activated. Sound production also stops.

Further, the output of the FF 22 is supplied to a reset terminal R of an FF 34, which will be described later, and at this time, the reset of the FF 34 is released.

The output 20a is also supplied to the AND gate 26 via the delay circuit 24, and the AND gate 26 is also supplied with the output 2c from the frequency divider in the clock circuit 2, which generates a 1 Hz signal. Therefore, the signal of the output 20a is generated at the output 24a of the delay circuit 24 with a delay of the delay time, and a 1Hz signal is generated at the output 26a of the AND gate 26 during the period when the output 24a is at the "H" level, and the signal is output to the counter 28. Supplied. As a result, when the snooze switch 18 is operated, a 1Hz signal is counted as one minute of the snooze time by the counter 28 according to the operating time of the snooze switch 18, and the count value of the counter 28, which is the snooze time data in minutes, is determined by the decoder 30. The data is converted into seconds and supplied to the data input terminal of the program counter 32. For example, when the snooze switch 18 is operated for 5 seconds, the count value of the counter 28 becomes "5" and "300" is supplied to the data input terminal of the program counter 32.

The present invention is characterized in that when the snooze time is set by operating the snooze switch, a snooze time confirmation sound, which is an intermittent sound corresponding to the snooze time setting, is emitted, and the snooze time confirmation signal generation circuit is configured. An AND gate 40 is provided.

The output 2b and the output 26b are supplied to the AND gate 40, and the output 40 of the AND gate 40 is
a is supplied to the OR gate 10. Therefore, every time a 1 Hz signal is generated at output 26a, a snooze time confirmation signal is generated at output 40a and supplied to OR gate 10, as shown in FIG. As a result, the snooze time confirmation signal is forcibly supplied to the sound generation circuit 16, and a snooze time confirmation sound is generated. Since this snooze time confirmation sound is synchronized with the 1 Hz signal supplied to the counter 28, it is possible to confirm the count value of the counter 28, that is, the snooze time, by listening to the snooze time confirmation sound.

Further, the output 20a is supplied to the set terminal of the FF 34, and the FF 34 detects the fall of the signal generated at the output 20a, that is, the end of the operation of the snooze switch 18. The output of the FF 34 is supplied to the AND gate 20 and the reset terminal R of the program counter 32, and the Q output of the FF 34 is supplied to the preset terminal PE of the program counter 32 via the one-shot circuit 36. Therefore, when the signal at the output 20a changes from the "H" level to the "L" level, the subsequent operation of the snooze switch 18 becomes invalid, the reset of the program counter 32 is canceled, and the snooze signal from the decoder 30 is sent to the program counter 32. Time data is preset. The program counter 32 is then supplied with the 1 Hz signal generated at the output 2c, and starts counting the snooze time.

Further, the single pulse generated at the output 36a is supplied to the reset terminal R of the counter 28 via the delay circuit 38, and the count value of the counter 28 is cleared.

When the program counter 32 finishes counting the snooze time, a count end signal is generated at the output 32a to reset the FF 22. Therefore FF
Since the output of 22 becomes "H" level, the output 8a
An alarm signal is generated again, and the sound generation circuit 16
An alarm sound is sounded and the FF 34 is reset. As a result, the output of the FF 34 also becomes "H" level, so the program counter 32
goes into the reset state and the snooze switch 1
8 becomes effective, and the state returns to the state before operating the snooze switch 18.

Therefore, subsequent operations of the snooze mechanism are performed in the same manner, and when the snooze switch 18 is operated, the alarm sound is first stopped, and the alarm sound is stopped after the delay time in the delay circuit 24 has elapsed until the end of the operation of the snooze switch 18.
A snooze time confirmation sound, which is an intermittent sound with a period of seconds, is emitted, and when the operation of the snooze switch 18 is completed, a snooze time corresponding to the number of intermittent sounds is set. After the set snooze time has finished counting, the alarm sound will be sounded again.

As described above, according to this embodiment, when setting the snooze time by operating the snooze switch 18, the snooze time confirmation sound is emitted in synchronization with the snooze time being counted by the counter 28. The set snooze time can be accurately recognized.

Moreover, in this embodiment, since the delay circuit 24 is provided so that the snooze time confirmation sound is not emitted consecutively with the alarm sound, there is an effect that the snooze time confirmation sound is easier to listen to.

Further, this embodiment can be configured by simply adding a few gates, and can be made at low cost.

As described above, according to the present invention, it is possible to provide a snooze watch that can accurately recognize the set snooze time in a device that allows the snooze time to be set in accordance with the operating time of the snooze switch. To eliminate a user's anxiety in setting a snooze time and to set an appropriate snooze time.
