Description

[Detailed description of the invention] The present invention relates to a wristwatch with an alarm.

Especially regarding how to use that alarm sound. An object of the present invention is to provide a new function to the timer mechanism and stopwatch mechanism of a wristwatch by combining them with an alarm blue, thereby further increasing the utility value of the alarm wristwatch.

FIG. 1 is a block diagram schematically showing an alarm-accompanied timepiece according to the present invention.

Crab watches usually use a crystal oscillator with a total oscillation frequency of 32.7 HZ as the time signal, and these are connected to the oscillation circuit 1.
Together they form one block. The output from the oscillation circuit is sequentially divided into two equal parts by the frequency dividing circuit 2, and finally becomes a one-second pulse signal. The 1 second pulse signal is evolved by counter 3 to 6G ships or 12 ships at time t.
It becomes a time signal in seconds.

These time signals are then translated into seven segment display signals by the decoder W and applied to the display drive circuit 5. The drive circuit that receives the output signal from the decoder operates the display using a drive voltage and drive method suitable for the liquid crystal or LED display device 9 to give us time information.

In addition, the alarm wristwatch according to the present invention includes a timer mechanism 7 that uses a counter output and an external operation 12 to detect coincidence with a preset time and notify the coincidence time. gives us display information such as the time through the display mechanism, and at the same time outputs a sound signal through the sounding element drive circuit 8.
consists of a small electromagnetic or piezoelectric buzzer. In addition to the timer mechanism, it also includes a stopwatch mechanism 6, which further divides the output from the frequency dividing circuit 2 to 1/10.
A pulse signal is obtained for the inkstone sand, which is started and stopped by an external operation 11. The measured time of the stopwatch can be determined by changing the channel on the display, which will tell us the time during the measurement or as a result of the measurement.

Furthermore, the electronic timepiece of the present invention has an external operation switch 1 shown in FIG.
The timer mechanism, the stopwatch machine, and the sounding body disturbance circuit are designed to work together so that the start signal (blue) will be emitted at the same time as 1 is operated, or after a certain period of time. For example, the start sound is ``Similar to the time signal, three short intermittent tones followed by one long tone one octave higher, and the last long tone is synchronized with the start of the timer and stopwatch.In this way, the start is announced, so use it. In addition, by using the time measurement function of a stopwatch and the time coincidence detection circuit of a timer, a new function is created that indicates the start and end of a certain time interval using blue. If you input a certain arbitrary time interval into the timer 7 using the turtle 2 and have the stopwatch 6 start and measure the time, the timer T will compare the measured time from the stopwatch with the set time and calculate the time. When they match, the end time can be notified.Therefore, the function of the alarm sounding device according to the present invention is as follows: 1. Notify the designated time.

2. Notify the beginning and end of a certain time interval.

3 Notify the start of stopwatch measurement.

It can be summarized into three points. In the following, the advantages of the present invention will be explained using a simple usage example. Application example of function 1 1 Advance notice of departure time of trains, buses, airplanes, etc. 2
Make use of your awareness.

3 Announcement of scheduled times for meetings and press conferences.

etc.

Application example 1 of function 2: When a process or action must be performed within a limited time such as heating time or measurement time during an experiment.

2 Measurement of pulse.

3. When there is a designated time such as heating time for food.

4. Signals for the start and end of exam time.

5 Signals for the start and end of a competition held within a limited time.

6. When limiting the meeting time.

7. When there is limited time for a speech.

etc.

Application example of function 3 1 Start practice and time measurement for track and field swimming competitions.

2. Starting signal and time measurement for a game that competes for time.

As described above, the effects of the alarm wristwatch according to the present invention include not only eliminating the need to constantly check the time display, but also the fact that the start sound consists of the start sound and the warning sound that is generated before the start sound. It surpasses conventional methods in so many ways that it makes it convenient for one person to handle both the measurement of time and the actions that must be performed during that time, which previously required human intervention, and "expands its scope of use several times over." The simple diagram of the drawing is a block diagram for explaining the alarm wristwatch according to the present invention.
