Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to additional functions of a multifunctional digital electronic watch.

With the development of digital electronic watches, various additional functions have been considered and are being put into practical use, with a stopwatch function being a particularly representative example.

The present invention realizes a new additional function of a digital electronic watch, and counts and displays multiple scores in sports, games, etc.

Although multifunctional watches having a simple single system of counters have been considered, it has not been considered to operate two or more systems of counters in parallel and display their comparison simultaneously.

The purpose of the present invention is to count and display the numbers of two or more systems of counters to enable easy and accurate counting in sports such as volleyball, basketball, tennis, baseball, and table tennis.

Also, in traffic surveys, etc., it is possible to count each direction, vehicle type, etc. separately, which is very effective.

Another object of the present invention is to provide a counting method that allows not only amplifiers to be counted down, but also to compare the remaining numbers from a specific value, and to provide a means for correcting when the count is too high when counting up. It's about doing.

Next, the present invention will be explained in detail with reference to the drawings.

FIG. 1 is a plan view of an embodiment of the present invention, which includes a display section and switches 1-3.

A indicates the status of the clock function, and the time 12:58:32 is displayed on the liquid crystal panel or the like.

The part indicating 32 seconds can also indicate the date by switching 1 or 2.

Switches 1 to 3 are used to adjust the time.

If switch 3 is pressed from the steady point in the LOCK state, it will change the channel, and if it is pulled out, it will be unlocked and the time will be adjusted.After that, each time switch 1 is pressed, the digit selected by correction digit selection switch 2 will be changed. The numbers are corrected by increasing by +1.

Modified digits are clearly indicated visually by flashing, etc.

As mentioned above, the channel A is no different from a conventional digital clock, but when you press switch 3, it changes to the score counting function of B.

In Figure 1, two scores are displayed, 17 vs. 18. If you press switch 1, the score on the left side will count up by +1, and if you press switch 2 on the right side, the score on the right side will count up by +1.

Therefore, if you use the left and right switches with your fingers, you can accurately count and show the score without looking at the display while keeping your eyes on the game, making it very easy to use for games such as Seports.

The switch is shared with the clock function of the A channel and is efficiently used in the present invention.

In the embodiment shown in FIG. 1, there are two score counts, but it goes without saying that by increasing the number of display units and switches, it is possible to have three or more score counts.

To explain the reset method, pull out switch 3 on the score count channel to enable resetting, and press switch 1 to reset the left score to 00, and press switch 2 to reset the right score to 00.

If switch 3 is pressed on the channel with the score count of +1 as described above, the channel with the score count of -1 is entered.

The operation is the same as that of a channel with a +1 score count, except that the left and right scores decrease by 1 with switches 1 and 2.

However, the reset function is excluded because reset itself has no meaning.

Furthermore, when switch 3 is pressed, the channel of the stopwatch is changed and the display 00 minutes 03 seconds 8 appears in FIG. 1C.

If you press switch 1, you can control start and stop, and if you press switch 2 in the stopped state, it will be reset to 00 minutes 00 seconds 0.

This can be done in sports such as basketball, soccer, and other sports that have fixed game times, by keeping track of the score only during that time according to the counting time of the stopwatch.

Since it has a start/stop switch, you can accurately respond to break times and time requests, and it can also be used freely as a standalone stopwatch.

Figure 2 shows the movement of each channel according to the present invention, and each time switch 3 is pressed, the clock → +1 score counter →
-1's score counter → stopwatch → clock and multiple functions change cyclically.

The clock channel allows you to adjust the time, and the +1 score counter allows you to reset it.

FIG. 3 is a block diagram of an embodiment of the invention.

DSP is a display means, DEC is a decoder, and SEL is a display information selection means.

4 is a clock function section, 5 is a score count function counter divided into left and right and R, 6 is a stopwatch function section, 7
is a control section that controls each function using switches 1 to 3.

In the present invention, since each of the functions 4 to 6 exists independently, each piece of information does not disappear even when changing channels, which is very convenient.

FIG. 4 shows an embodiment of a counter constituting the score counter of the present invention.

Reference numerals 8 to 11 are all 4-bit BCD output decimal counters, which are general set-up counters consisting of flip-flops, count by 1 each time a clock is input, and have a reset input and an up/down switching input.

Every time switch 1 is pressed, the clock from LI is input to 8, and every time switch 2 is pressed, the clock is input from RI to 1.
It is input to 0.

8, 9, 10, and 11 are connected by carries, respectively, and together form a 100-decimal counter, which has BCD outputs of 4 digits, 20 to 23, of 2 digits on the left and right.

Reset is 8 and 9 by RL, 10 and 1 by RR
It can be done separately from 1.

In the +1 score counter state of Figure 2, UP/DOWN
The terminal is switched up, and switched to down when the score counter is -1.

The above counter may be configured as a serial counter using a shift register, in which case the clock section and stopwatch section can be connected together in series and operated in a time-division manner, thereby simplifying the output switching circuit.

In the present invention, the score counter and the stopwatch are organically linked to obtain more functions, but whether the stopwatch is started or stopped can be determined by the presence or absence of flashing of the colon in the display state of the score count. It can also be made to be distinguishable.

If you add a timer function to your stopwatch, you will be able to instantly recognize when the timer setting time (game time) has arrived, and it will be very convenient.

If you make a buzzer sound at that time, you can be notified more reliably.
