DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stopwatch device for measuring measurement times of a plurality of persons to be measured.

[0002]

2. Description of the Related Art A conventional stopwatch device stores and displays the measured time of a plurality of persons.
No. 61, column 2, line 5 to column 3, line 6 and FIG.

[0003] For example, when practicing 5,000 m (track 400 m) running of athletics, the elapsed time (split time) for each lap from the start is continuously measured and stored. The section time (lap time) is calculated from the stored elapsed time and displayed. However, it is difficult to make the measurement target correspond to the measurement time in the counting after the measurement is completed, and it is finally impossible to measure one person with one stopwatch device. In the first round, a plurality of people gathered to form one group, and measurement was performed by pressing a split (lap) switch for each group. When eight people were forming a group, the split switch was continuously pressed eight times to obtain a measurement time for each measurement subject.

[0004]

However, it is difficult for a conventional stopwatch device to measure two or more persons to be measured with one stopwatch device. Was only measuring.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a stopwatch device in which a single stopwatch device can easily perform measurement and memory management of a plurality of persons by designating a measurer.

In the measurement forming a group,
Another object of the present invention is to make the group creators the same time and to facilitate later measurement and aggregation.

It is another object of the present invention to quickly correct and replace measurement data even when measurement is mistakenly performed.

The names of a plurality of persons to be measured are entered in the numeric keys of the keyboard 23. Up to eight measurement subjects can be registered, but in the embodiment, one key: Matsui,
3 keys: Ochiai, 6 keys: Hara, 8 keys: Okazaki. Also, a registration key that assigns the measurement target to the numeric key as a special key, an all-keys that sets the measurement time to all measurement target (registrants), and a replacement that replaces the measurement time once stored in one person with the time of another person Key, clear key to cancel entered numeric keys, RAM
11 has up / down / left / right keys for retrieving the measurement data stored in 11. The up and down keys call the same measurer's lap number up and down, and the left and right keys call between the measurers up and down in player number order.

According to the above configuration, a key and a memory area are allocated to each person to be measured.
In the embodiment, up to eight persons can be measured.

FIG. 3 is a detailed RAM diagram showing the details of the RAM 11 for storing measurement data according to the present invention. In the embodiment, four persons are registered as shown in FIG. 2, and a memory area for four persons is secured. The address X stores a personal number corresponding to the numeric key. Address A: Matsui (1), Address B: Ochiai (3), Address C: Hara (6), Address D: Okazaki (8). Address E,

Stores the number of splits. In the address Z1 to the address Z30, the split time is sequentially stored for each person. That is, the maximum number of memories is always 30 regardless of the number of measurers.

According to the above-described configuration, each key is assigned to the person to be measured. Therefore, before Mr. Matsui passes the measurement point, he presses the 1 key to specify Mr. Matsui, and when passing the measurement point, the switch A is pressed. When is pressed, it is stored in the RAM 11 as the measurement time of Mr. Matsui. Since data is stored for each personal number area, the measurement time, the average value, the rank, and the like for each individual can be easily calculated and displayed.

In order to obtain measurement times of a plurality of measurement subjects, it is necessary to register the measurement subjects in advance.
Hereinafter, the registration method will be described.

First, when the registration key is pressed in the reset state,
“Registration” is displayed on the display unit 14 and the registration is accepted.
FIG. 6A shows this state, in which the frames of the previously registered player icons 1, 2, and 3 are blinking to indicate that they are registered. Here, the person to be measured is associated with the numeric key. That is, the numeric keys 1 (Matsui), 3 (Ochiai), 6 (original), and 8 (Okazaki) are associated with each other, and a name is written near the associated numeric keys as shown in FIG. Then, the number key 2 is pressed to turn off the frame of the player icon 2. Next, when the numeric keys 6 and 8 are pressed, the frames of the player icons 6 and 8 are added, and the frames of the player icons 1, 3, 6, and 8 flash as shown in FIG. 6B. When the registration change is completed, when the registration key is pressed again, "Registration" disappears as shown in FIG. 6C, the set frame is turned on, and the registration of four persons is completed. In FIG. 6C, “1” in the upper left corner
Indicates the smallest registered player number, and "00" indicates the number of laps. "0
"0" indicates that there is no lap count.

FIG. 4 is a flow chart of a measurement process in which a plurality of persons of the stopwatch device according to the first and second aspects of the present invention set the same time. Hereinafter, the operation of this flowchart will be described.

First, the switch A is pressed to start time measurement, and the flow proceeds to "measurement processing" (S30). When a key is pressed just before the measurement point, it is determined that the key has been pressed. "Key input?" (S31) determines that the key has been pressed and determines whether all the input keys are all keys.
Proceed to 2). Here, if it is determined that the keys are all keys, "frame flashing" (S33) indicating that the frames of all four registered members are flashed is executed, and "END" is ended.
Proceed to (S41). If the keys are not all keys in step 32, it is determined whether the input is a numeric key.
Proceed to 34). In the case of a numeric key, "numeric key processing" (S35) for taking in the numeric key is executed. In step 35, a process is performed to determine whether the pressed numeric key is a registered key. If a non-registered numeric key is pressed, it is ignored. For example, when the numeric key 2 is pressed, it is ignored. When a registered key is pressed, a frame indicating the pressed key blinks to indicate that the key has been designated, and "frame blinking" (S3
Proceed to 6), and proceed to “END” (S41) at the end of the measurement process.

On the other hand, if there is no key input in step 31, the process proceeds to "SWA input?" (S37) for determining whether switch A has been pressed for time measurement. Switch A
At the time of input, the process proceeds to "frame blinking" (S38) for determining whether there is a frame blinking. If the frame is blinking in step 33 or 36, "store in memory" (S39) for storing the measurement time (elapsed time) when switch A is pressed in the personal number area of the blinking person is executed, “Frame blinking release” (S40) for setting the blinking of the frame to the lighting state is executed, and the process proceeds to step 41. If there is no frame blinking in step 38, the input of the switch A is ignored and the process proceeds to step 41.

The measuring method is to press the numeric key of the measurer shortly before the measurement point, designate the measurer, press switch A at the measurement point, and store the measurement time in the memory (RAM 11).

A description will be given of an example in which a 5,000 m run is measured for each lap of a 400 m track and the time is stored. 1
On the lap, four people form a group at the measurement points. On the second lap, Matsui and Ochiai were in the first group and Hara and Okazaki were in the second group. The third lap will be Matsui, Ochiai, Hara, and Okazaki.

In the first lap, the key for all members is pressed, so that the frame of all four members blinks in step 33 and all members have the same time in step 39. The memory state is changed to address Z in FIG.
It is shown in FIG. FIG. 6D shows the display state. In FIG. 6, the upper part is a lap display, and the lower part is an integrated time. The lap time is calculated from the stored split time. In the case of a plurality of measurers, data of the person with the smallest player number is displayed. Here, Matsui's data is displayed. If you want to see the data other than by the viewer, call it with the arrow keys.

In the measurement of the second lap, the switch A is pressed after the numeric keys 1 and 3 are pressed, so that Matsui and Ochiai have the same time. The display state is shown in FIG. Then, after the numeric keys 6 and 8 are pressed, the switch A is pressed, and Hara and Okazaki are stored as the same time. The memory state is changed to address Z in FIG.
It is shown in FIG.

In the third round of measurement, the switch A is pressed after the numeric key 1 is pressed, and the measurement time is stored in the memory area of the RAM 12 only for Matsui. Then, after the numeric key 3 is pressed, the switch A is pressed, and only the Ochiai RAM 12
The measurement time is stored in the memory area of. Then, after the numeric key 6 is pressed, the switch A is pressed, and only the original RA
The measurement time is stored in the memory area of M12. After that, after the numeric key 8 is pressed, the switch A is pressed, the measurement time is stored in the memory area of the RAM 12 of only Okazaki, and the measurement of the third lap is completed. The memory state at this time is shown at address Z3 in FIG.

According to the above-described configuration, when all the members form a group and pass through the measurement point, the measurement can be performed by two switch operations, and the measurement time can be the same.

In the above-mentioned 5000m run, 4
Although the lap is limited to the lap every 00 m, if the lap every 400 m and the 1 lap every 1 km can be measured and displayed, the manager and the coach can easily manage the pace of the players, which is very convenient.

Therefore, an example in which a plurality of different laps are assigned and registered instead of assigning and registering a plurality of players as described above will be described.

For example, consider the case where the numeric key 1 is assigned to a 400-m lap and the numeric key 2 is assigned to a 1-km lap for the same player. In this case, in the first round measurement, the numeric key 1 is pressed and then the switch A is pressed, so that the measurement time at the time of 400 m is stored in a predetermined memory area (address Z1, A) of the RAM 12. In the measurement of the second round, the numeric key 1 is pressed and then the switch A is pressed, so that the measurement time at the time of 800 m is set in a predetermined memory area of the RAM 12 (address Z2,
A). Then, by pressing the numeric key 2 before the point 1 km and then pressing the switch A, the measurement time at the point 1 km is stored in a predetermined memory area (address Z1, B) of the RAM 12.

In this case, for example, 400 m at a point of 2 km
The lap and the 2km lap are at the same time, but press the switch A after pressing the all-keys, or specify 400m and 1km (after pressing the numeric keys 1 and 2), as in the above group formation. If 400m
And the same time is stored in the memory area (address Z5, A and address Z2, B) corresponding to 1 km. In such a case, printing on the key tops, such as the key for all / simultaneous keys instead of the key for all, allows the key to be shared by one key (the operation of specifying the measurement target and the time measuring operation can be performed simultaneously).

The registration of a plurality of players and the registration of a plurality of laps can be used in combination. For example, in FIG. 2, different laps of the same player may be assigned to the unregistered 2, 4, 5, and 7 keys.

FIG. 5 is a flowchart of the replacement process of the stopwatch device according to the third and fourth aspects of the present invention. As shown in FIG. 4, for the time measurement, a measurement subject is specified, and the measurement time is stored in the memory area for the specified user by the switch A. However, for example, in the measurement of the second round, when Matsui and Ochiai are erroneously measured as Ochiai and the original, it is necessary to quickly replace the stored data from the original with the Matsui. In such a case, a "replacement process" (S50) is executed.

As an example, a case will be described in which Matsui and Ochiai were originally measured as Ochiai and the original. As a result of step 40 (FIG. 4) after the switch A is pressed, the measurer frames 3 (Ochiai) and 6 (original) are turned on. Here, when the replacement key is pressed after noticing the error, the flow proceeds to "Replacement key?" (S51) for determining the replacement key input. It is determined whether the replacement flag is set because the replacement key is pressed.
= 1? (S52). In this state, the replacement flag =
Since "0" is set, the "replacement flag" is set (F53) (S53), the "replacement" flag is lit on the display unit 14, and the lit player frame is blinked.
Proceed to 4). This is shown in FIG. Then, "previous data deletion" (S55) for deleting the latest measurement data of the Ochiai and the original stored in the memory from the memory is executed. That is, it is known from the data of the measurer frame to whom the data was last stored, and this data is deleted. Here, the memories of the addresses B and C of the address Z2 in FIG. 3 are erased, and the measurement data of the second cycle is deleted from the memory area for each individual. Then, the process proceeds to “END” (S63) of the end.

If it is not the replacement key in step 51, it is determined whether the replacement key is standing.
Proceed to (S56). When the replacement flag is 1, the flow proceeds to "setting key?" (S57) for determining whether the pressed key is a numeric key and a registered key. In the case of a setting key, the "Replacement input display" (S
58). In step 58, the frame is released if the pressed key frame is surrounded, and a frame is provided if there is no frame. That is, first, the numeric key 6 is pressed, and the operator frame 6 is released. Next, the numeric key 1 is pressed, and the operator frame 1 is provided. The frame of Ochiai is now unchanged, and the frame of the original is changed to the frame of Matsui. This is shown in FIG.

When the replacement key is pressed again, it is determined in step 52 that the position F = 1. Therefore, the process proceeds to “Is there a frame?” (S59) to determine whether or not there is a measurer frame. In the case of the measurer frames 1 and 3 as in the example, the process proceeds to "memory storage" (S60) in which the measurement data is stored in the players having the personal numbers 1 and 3. That is, the measurement data of the second lap (1:43:12)
Is newly stored at addresses A and B of address Z2 in FIG. 3 as a measurement time of Matsui and Ochiai. Then, the "replacement flag is reset to" 0 "(S6).
1) Turn off the "replacement" on the display unit 14 "turn off the replacement"
(S62) is executed. The display is as shown in FIG.

When all the measurer frames are released in step 58, the process proceeds from step 59 to step 61, and the latest measured data is not stored in the memory as the measurer data. That is, when measurement is erroneously performed during measurement, erroneous measurement data can be erased during measurement.

According to the above configuration, when another person is mistakenly measured, the measurement data can be replaced with the original person.

FIG. 6 is a display example in the embodiment of the stopwatch device according to the present invention, and shows various states already described.

[0045]

As described above, the stopwatch device of the present invention has the following effects.

According to the first aspect of the present invention, the same measurement data can be used as measurement data of a plurality of persons when a group passes a measurement point. Therefore, it is not necessary to operate the apparatus for each individual person to be measured, and accurate measurement can be performed with one stopwatch.

According to the second aspect of the present invention, all the measurers can use the same measurement data by a simple operation.
For this reason, when all the persons to be measured form a group and pass through, the operation becomes very simple and the usability is improved.

According to the third aspect of the present invention, the measurement data erroneously measured can be replaced with the original person. In particular, when there are a plurality of measurement subjects, such erroneous measurement is likely to occur, and correction and replacement can be easily performed, so that an accurate measurement time can be obtained. Above all, since there is no erroneous data correction work after the end of the time measurement, data aggregation becomes very easy and can be performed quickly.

According to the fourth aspect of the present invention, measurement data erroneously measured can be erased during measurement to invalidate the measurement. Therefore, by immediately canceling the erroneous measurement data, the next and subsequent measurements can be quickly and correctly performed.
