Abstract

PURPOSE:To enable stopping of an alarm sound only when a complete awakening comes about, by stopping the generation of the alarm sound through comparison of a key input information given when the alarm sound is generated with a prescribed alarm stop information. CONSTITUTION:When a set time of an alarm setting memory 5 coincides with a present time according to a time-count counter 3, an alarm sound driving circuit 7 is controlled through the intermediary of a comparator 6 and an alarm sound is generated from a sounding body 8. When a numeric key is operated, at this time, corresponding to a set alarm time after operating the alarm stop key ALS of a key input unit 9, a key input is memorized temporarily in an input buffer circuit 11 for the alarm stop and compared with the present time by a comparator 10. Then, the circuit 7 is controlled by a coincidence output from the comparator 10 and thereby the alarm sound is stopped. Accordingly, the alarm sound can not be stopped unless the key input unit is operated correctly after complete awakening.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in an electronic timepiece with an alarm.

In a conventional general electronic watch with an alarm, an alarm sound continues to sound when the alarm set time comes, and in this case, the alarm sound can be easily stopped by pressing an alarm stop button.

However, if a person who sleeps too much in the morning uses such a clock, the alarm may turn off without fully waking up, and then fall asleep again. Therefore, such people need a watch that makes it difficult to turn off the alarm sound.

The present invention has been made in view of these points, and provides an electronic clock with an alarm that cannot be stopped unless the person is completely awake.Hereinafter, according to an embodiment of the present invention shown in the drawings, explain.

FIG. 1 shows a block diagram of one embodiment of the present invention, where 1 is a reference oscillator that has a crystal oscillator and the like and oscillates a reference signal, and 2 is a reference oscillator that oscillates a reference signal from the oscillator 1. A frequency divider that divides the frequency, for example, IHz; 3 is a time counter that performs a time counting operation based on the IHz clock signal divided by the frequency divider 2; and 4 displays the contents of the counter 3 as a time. a display device; 5 an alarm setting memory for storing a desired alarm setting time; 6 a comparison between the clocked time counted by the clock counter 3 and the alarm setting time stored in the alarm setting memory 5, and only when the two match; a comparator for deriving an output signal; 7 is an alarm sound drive circuit that triggers and outputs an alarm sound signal when a matching output is derived from the comparator 6; 8 is an alarm sound drive circuit for outputting an alarm sound signal derived from the drive circuit 7; This is a sounding body such as a bell or a speaker that generates an alarm sound based on the alarm sound, and these constitute an electronic timepiece with an alarm similar to a conventional electronic timepiece.

Here, in such an alarm watch, there are a plurality of numeric keys 9', 9'... and various function keys 9.
#, 9", etc. A desired alarm setting time can be arbitrarily written and set in the alarm setting memory 5 by key operation of the key manual device 9. In other words, this alarm setting time can be set by, for example, If you want to set it to 7:30, first press function keys 9#, 9.
After pressing the alarm setting key rALJ, which is 01, select the numeric keys 9', 9'... and press the numeric keys ``7'', ``3'', and ``0'' corresponding to the time in sequence. For example, this is input to the alarm setting memory 5, and at this time, the display device 4 displays the alarm setting time information from the memory 5 (7:3
0) is displayed for a certain period of time, for example, 30 seconds, so that the settings can be confirmed during this time, and thereafter, the current clock time information is displayed again.

In this embodiment, as described above, an electronic clock with an alarm equipped with a key manual device 9 is provided with a comparator 10 for alarm stop and an input buffer circuit 11. The measured time information is supplied as an alarm stop key. Now, for example, at 7:30, the clock time information of the clock counter 3 matches the setting information of the alarm setting memory 5, a matching output is derived from the comparator 6, and the alarm sound drive circuit 7
is triggered and the sounding body 8 generates an alarm sound. Therefore, at this time, after pressing the alarm stop key rALsJ, which is one of the function keys 9'' of the key-powered device 9, the alarm stop information device is set to a numerical value L corresponding to the time information at that time, for example, "7", "3"
, "0" are pressed in sequence, these are supplied to the comparator 10 via the alarm stop manual buffer circuit 11. If you do not wake up properly and press the wrong key, no matching output will be obtained from the comparator 10, the alarm sound drive circuit 7 will be driven, and the sounding body 8 will continue to emit an alarm sound. Become. Only when the user is completely awakened by this alarm sound and performs a correct key operation, a matching output is derived from the comparator 10, which stops the operation of the alarm sound drive circuit 7 and stops the alarm sound emitted from the sounding body 8.

In this way, in this embodiment, the time information at that time is used as the alarm stop information, and when the alarm sound starts to sound, the generation of the alarm sound is stopped when numerical information corresponding to this information is accurately input using the key input device. .

Note that, as in the other embodiment shown in FIG.
In the case of an electronic watch with an alarm, the month and day information obtained from this month and day counter is used as alarm stop information, and the clock time information and alarm setting time information are used in the same way as the operation of the embodiment shown in FIG. When the alarm sound starts to sound from the sounding body 8 in accordance with
If it is the 5th day, a matching output is derived from the comparator 10 by pressing the alarm stop key rALsJ and then sequentially inputting numeric keys "6", "1", and "5". The alarm sound can be stopped.

According to the electronic watch with alarm of the present invention, as described above, the clock time information or month/day information is used as the alarm stop information, and when the alarm sound starts, information matching the alarm stop information is accurately transmitted from the key manual device. The alarm sound can be stopped only when an input is made, and the alarm sound will not continue sounding if the key is operated without fully checking the alarm stop information at that time, making it particularly suitable for use by people who tend to sleep late in the morning.
