In this way, an efficient utilization processing which an ordinary stop watch cannot execute can be executed.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a sports watch that stores and displays lap times from the start to the end or during the course of various competitions, and is capable of directly calculating the relative elapsed time of each lap time.

Conventionally, stopwatches used to measure time in various competitions have become commonplace with digital displays equipped with an IC mechanism, allowing efficient measurement by immediately displaying the lap time from the start using a button switch. be. However, since this stopwatch does not have a storage mechanism for the displayed lap time, it is impossible to recall the displayed lap time after it has been cleared, and each lap time must be written down on a paper each time. There were drawbacks such as the need for time and effort to calculate the elapsed time between times.

In order to solve the above-mentioned drawbacks, the present invention is a sports watch that integrates functions such as a clock, an alarm, a stopwatch, a counter, and a memory calculation into a compact size, and is designed to reduce the time required for several people or several places. can be easily measured by one person and memorized while displaying each person's lap time from the start to goal 1 or halfway, and it is also easy to calculate and compare the required times between each other using the calculation function. It is something.

Hereinafter, the present invention will be explained in detail with reference to embodiment figures.

On the top plate 11 of the case 10, there are address numbers, Zetsuken numbers, and numeric keys 12 from 0 to 9 for their numerical values.

3 and the storage element 34, and the data calculation command unit 36
and a memory element 34 are connected to a power calculator 37, and the calculator 37 is connected to a display selector 28 to constitute a sports watch 38.Next, the operation of the present invention will be explained with reference to embodiment diagrams. Explain the effect.

The sports watch 38 according to the present invention can be used as a time-opener by pressing the mode key 15 after turning on the power, or
When the 0 mode key 15, which is used to switch the use as a stopwatch, is set as a clock, the clock pulse signal of the clock function section 26 is sent via the display selector 28 to the display sections 22a and 22b. , day, day of the week, hours, minutes, and seconds, and the alarm time can be set using the alarm key 16, timer key 17, and numeric key 12, and the display correction key 1
8 and ten key 12 are used to set the date and time. Next, when using it as a stopwatch, press the mode key 15 once to switch to a stopwatch, and a signal is transmitted from the time mode terminal of the interface 23 to the mode selector 27, turning it on.
When the start key 20 is pressed once to turn it ON, a start signal is transmitted from the start terminal of the interface 23 to the clock gate 29, turning it ON, and the clock function section 26
A clock pulse signal is input to the time counter 30 via the mode selector 27 and the clock gate 29, and the time counter 30 starts counting from zero and displays the counted time on the display section 22b via the display selector 28. When the required time is reached, press the start key 20 again and the interface 23 will be displayed.
A stop signal is transmitted to the clock gate 29 from the stop terminal of the clock gate 29 to turn it off, and the time counted by the time counter 30 is displayed on the display section 22b.This display mechanism can be used in the same way as a stopwatch currently in use. If you want to use it as a special stopwatch that memorizes and displays intermediate lap times, or performs calculations, rather than an ordinary stopwatch, press the start key 20 once to turn it on and output the clock pulse signal. is input into the time counter 30, the time from the start is displayed on the display section 22b via the display sector 28, and when taking the lap time on the way, the time key 2 is input.
When 1 is pressed, a signal is transmitted from the check terminal linked to time key 21 to time reader 32, increment 33, and address selector 35, and time key 2 is pressed.
The number of times 1 was pressed (lap number) is sequentially stored as an address number in the memory element 34 in correspondence with the measurement time of the counter, and the lap number is displayed on the display section 2.
2a. To recall the stored lap time, press the lap number on the numeric keypad 12 and then press the total key 14. A signal is transmitted from the addressing of the interface 23 to the address selector 35, and the data stored in the storage element 34 is used for data calculation. Command unit 36
the display section 22 through the calculator 37.
The lap number is displayed on a and the lag time is displayed on the display section 22b. Therefore, in a sport where many people finish at the same time, such as swimming, you can press the time key 21 each time you cross the finish line, and then easily call up the required time using the lap number. Lap times such as every 100 meters can be memorized very easily, so press the time key 21 every 100 meters to memorize the lap times, and during practice,
Alternatively, if you want to call up the lap time for, say, 500 m after practice, press 5 on the numeric keypad 12 and the total key 14 in sequence, and 5 will be displayed on the display section 22a and the required time will be displayed on the display section 22b, allowing you to know the lap time for 500 m. ,
For section lap times, for example, if you want to know the section lap time from 1400m to 1500m, press numeric key 12, calculation key 13, and total key 14 (1
5-142), the required lap time is immediately displayed on the display section 22b.

Also, when multiple people start and finish at staggered times, you can first press the start key 20, then press the time key 21 in time with each person's start, and then press the time key 21 again each time you reach the goal. If you start at 3 and the lap number at the finish line is 15, you can press the keys (15-3-) to immediately calculate and display the time required for that person.
Although the lap number corresponds to the address number of the memory element, the memory element may be programmed so that the contestant's number corresponds to the address number.
Especially in competitions like marathons, it is convenient to memorize the Zetsuken number. After measuring the lap time using the time key 21 and performing arithmetic processing on various data, pressing the start key 20 clears all information. Arithmetic keys 13.13' are (-) and (
×) is displayed, but the keys for (=) and (×) are 90
It can be converted into addition and division by rotating it by degrees, and it can also be used as a calculator by using the numeric key 12, calculation keys 13 and 13', and maxim 1 key 14. The number of presses is displayed on the display section 22a and can also be used as a counter.

In short, the present invention is characterized in that a storage and calculation circuit is attached to the circuit of a digital stopwatch so that it can perform efficient utilization processing that is not available in conventional stopwatches. It has various remarkable effects such as
