Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to an improvement of an electronic watch with a snooze function that restarts alarm notification after a certain period of time after stopping alarm notification.

(Prior Art) Conventionally, a so-called snooze function has been known, such as Japanese Patent Publication No. 56-24231, which restarts alarm notification after a certain period of time has passed after stopping alarm notification. The snooze function is started by operating a snooze switch that is installed separately from the alarm silence switch, but in recent years, as in Japanese Patent Publication No. 55-44360, the snooze switch is not installed independently, and For example, some switches also function as time adjustment switches.

(Problem that the invention aims to solve) In these conventional electronic watches with a snooze function, the snooze time interval, that is, the time from when the alarm stops sounding until it starts sounding again, is fixed, and it can be adjusted according to the user's will. Moreover, even if the user wanted to change the time of the next notification depending on the condition when he woke up in the morning, he was unable to do so.

The present invention was devised in view of the above-mentioned conventional problems, and its purpose is to provide an electronic watch with a snooze function that allows the user to change the snooze time interval when attempting to activate the snooze function. .

(Configuration for Solving Problems) In order to achieve the above object, the present invention uses a snooze switch as a plurality of correction control switches of a watch, each of these switch groups starts counting, and each By providing a plurality of snooze counter groups that count the snooze time interval and restart alarm notification using the output signal, the snooze time interval can be varied depending on which switch is pressed to start the snooze operation. It is characterized by what it did.

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

FIG. 1 is a circuit diagram of an electronic watch with a snooze function according to an embodiment of the present invention.

The clock circuit 2 that displays the time includes an oscillator 4, a frequency dividing circuit 6, a clock circuit 8, a decoder/driver 10,
It includes a display section 12, which has the same configuration as a conventional watch. The alarm time matching circuit 14 that detects the arrival of the alarm time also includes an alarm counter 16 that stores the alarm time, and an alarm counter 1 that stores the alarm time.
6 and the clock circuit 8, and if they match, a matching circuit 18 outputs a matching signal, and a trigger circuit 20 converts the matching signal into a single pulse. The clock circuit 8 in the clock circuit 2 and the alarm counter 16 in the alarm time matching circuit 14
are connected to the correction control switch group 26 (in this embodiment,
An hour digit correction switch 28, a minute digit correction switch 30 and a seconds reset switch 32) are connected. The control input terminals of the AND gate groups 22 and 24 are
The Q output and the output of the FF 34 are respectively input, and the display changeover switch 36 is connected to the clock input φ of the FF 34. As a result, by operating the switch 36, the correction control switch group 26 is used for adjusting the current time or for adjusting the alarm time. Further, the Q output of the FF 34 is input to a display switching circuit 38 to which the clock circuit 8 and the output of the alarm counter 16 are input. The display switching circuit 38 is a circuit that selects and supplies the output of either the clock circuit 8 or the alarm counter 16 to the display section 12 by operating the display switching switch 36. Of course, it goes without saying that the correction control switch 24 is used to adjust the current time when the current time is displayed, and is used to adjust the alarm time when the alarm time is displayed.

On the other hand, a notification circuit 40 that generates an alarm notification sound
is a sound generation circuit 42 consisting of a speaker, an amplifier, etc.;
FF4 whose Q output is input to this sound generation circuit 42
4, and OR gates 46 and 4 input to the set input S and reset input R of the FF 44, respectively.
Contains 8. The OR gate 46 is configured to receive a single pulse from the alarm time matching circuit 14. The output of the FF 44 is input to a switch switching circuit 48 that switches the correction control switch 26 between correction and snooze. The switch switching circuit 48 includes AND gate groups 50 and 5.
2, an inverter 54 and an OR gate 56. All correction control switch groups 26 are input to the AND gate group 50, and their output signals are input to the AND gate groups 22 and 24. The output of the above-mentioned FF 44 is input to this AND gate group 50. Also, only the signals of the hour digit correction switch 28 and the minute digit correction switch 30 of the correction control switch group 26 are input to the AND gate group 52, and the output signals of the AND gate group 52 and the second reset switch 32 are input to the AND gate group 52. The signal is inputted to the OR gate 48 in the notification circuit 40 via the OR gate 56 . Furthermore, an inverter 54 is connected to the control input terminal of the AND gate group 52.
The output of FF44 via FF44 is input.

Furthermore, the outputs of the AND gate group 52 are input to snooze timers 58 and 60, respectively. The snooze timers 58 and 60 are circuits that determine the snooze time interval, and are composed of a counter with an oscillator, etc. In this embodiment, the snooze timer 58 has a snooze time interval of 5 minutes, and the snooze timer 60 has a snooze time interval of 10 minutes. is set to . The output signals of the snooze timers 58 and 60 are input to the OR gate 46 in the notification circuit 40 via the OR gate 62.

The auto-stop timer 64 is used to determine the time until the alarm automatically stops (12 minutes in this embodiment); its input is the output of the OR gate 46, and the output is input to the OR gate 48. ing.

The embodiment of the present invention has the above configuration, and its operation will be explained using the time charts shown in FIGS. 2a to 2c.

Before the set time arrives, the output of FF44 is "H"
Therefore, the AND gate group 50 in the switch switching circuit 48 is open and the AND gate group 52 is closed. Therefore, the correction control switch group 26 functions for correction.

When the set time arrives, a positive single pulse is generated at the output of the matching circuit 18 via the trigger circuit 20, and is input to the set input S of the FF 44 via the OR gate 46, making its Q output "H". . As a result, a notification sound is generated from the sound generation circuit 42 (time t ₁ ). Here, when the output of the FF 44 becomes "L", the AND gate group 50 is closed and the AND gate group 52 is opened. This causes the correction control switch group 26 to become a snooze switch.

After this, at time t ₂ , the hour digit correction switch 2
When 8 is pressed, its output signal becomes "H", and this signal is sent to AND gate group 52, OR gates 56 and 48.
input to the reset input R of FF44 via
Set the Q output of 44 to "L". Therefore, alarm notification is stopped. At the same time, the snooze timer 60 operates and outputs an "H" signal 10 minutes later (time _t3 ). This output signal is OR gate 6
2.46 to the set input S of the FF 44, and its Q output is set to "H". As a result, alarm notification is restarted. (Fig. 2a) On the other hand, if the minute digit correction switch 30 is pressed instead of the hour digit correction switch 28 after the alarm notification is made at time _t2 , the FF44 Q
The output becomes "L" and the alarm notification stops, but the snooze timer 58 operates instead of the snooze timer 60. Therefore, after 5 minutes (time
At time _t3 '), the snooze timer 58 outputs an "H" signal, which is input to the set input S of the FF 44 via the OR gates 62 and 46 as before. As a result, alarm notification is started again. (Fig. 2b) Also, at time _t2 , the second reset switch 32
When pressed, the "H" signal is input to the reset input R of the FF 44, setting the Q output of the FF 44 to "L" and stopping the alarm notification. However, in this case, neither of the snooze timers 58 and 60 is activated, so the alarm notification is not restarted and the alarm is completely stopped. (Fig. 2c) If no operation is performed after the alarm notification starts, the auto-stop timer 64, which started operating at the same time as the start of the alarm notification, will output an "H" signal after 12 minutes (time _t4 ). is input to the reset input R of the FF 44 via the OR gate 48. As a result, the Q output of the FF 44 becomes "L" and the alarm notification is stopped. (Fig. 2 d) (Effect of the invention) According to this embodiment, the snooze time interval is changed depending on whether the hour digit correction switch 28 or the minute digit correction switch 30, which is used as a snooze switch, is pressed. Users can choose the snooze time based on their physical condition and mood when they wake up in the morning. In addition, the correction control switch group 26, which also serves as a snooze or alarm silencer, has a correction control function disabled while an alarm is being reported, so if the switch is operated to snooze or alarm alarm silence, the watch may be incorrectly corrected. will not occur.

As described above, according to the present invention, the snooze time interval is varied depending on which of the multiple correction control switches used as the snooze switch is operated, so that the user can It becomes possible to select a favorite snooze time interval, and it becomes possible to provide an electronic watch with a snooze function that is extremely easy to use.
