That is, since the display unit 3 is not visible during use, the operator checks the game time, the 30-second rule time, the ball dominance rate of the left and right teams, and the like on the monitor unit 23.
[0027]
Next, the drive circuit unit will be described. In FIG. 4, 4 is the above-described various input key groups arranged in the operation unit 2, 24 is a selector for selecting a key, 25 is a key recognition unit for recognizing which key is selected, and 26 is a 30-second rule. 30 seconds timer for measuring 30 seconds of the game, 27 is a game time timer for measuring 20 minutes of the game time, 28 is a right team rule time timer for measuring the right team's ball control time, 29 is the ball control time of the left team These are left team dominating time timers to be measured, which operate in response to signals from the key recognition unit 25.
[0028]
Reference numeral 30 denotes a ball dominating rate calculation function unit, in which the dominating time data from the right team dominating time timer 28 and the dominating time data from the left team dominating time timer 29 are respectively input and added to the left and right teams The total time of the domination time timer is used as the denominator, and the domination times of the right team and the left team are each divided as the numerator, and the resulting ball domination rate is calculated for each of the right team and the left team.
[0029]
In FIG. 5, reference numeral 31 denotes a display switching function unit which receives time data from the 30-second timer 26, game time data from the game time timer 27, and ball control rate data from the ball control rate calculation function unit 30.

The buzzer controller 34 is operable upon receiving a drive signal CL from the frequency divider circuit 33.
[0031]
Numerical data such as game time, 30-second rule time, and right / left team ball dominance from the display switching function unit 31 are input to the next two decoders 37 and 38 and converted into seven segment signals, respectively. Are added to the display unit 3 through drivers 39 and 40, respectively.
[0032]
Here, the decoder 37 outputs a segment signal for inputting the numerical signal of the game time data to the upper display area 12A, and the decoder 38 applies to the time data of the 30 second rule or the ball dominance rate in the lower display area 12B. A segment signal for inputting a numerical signal is output. These segment signals are applied to the LEDs arranged in the display areas of the display unit 3 through the extrusion drivers 39 and 40, respectively.
[0033]

This digit signal is synchronized with the segment signals of the ejection drivers 39 and 40 and is input to the display unit 3 as a drive signal. 43 is a selector for driving the display of the monitor unit 23, receives the drive signal CL, and outputs a digit signal. A segment signal is input to the monitor unit 23 from the ejection drivers 39 and 40, and display driving is performed by a digit signal from the suction driver 44.
[0034]
The drive signal CL from the frequency divider circuit 33 includes the key recognition unit 25, a 30-second timer 26, a game time timer 27, a right team dominant time timer 28, a left team dominant time timer 29, and a selector of the display unit 3. 41 and the selector 43 of the monitor unit 23 are input to enable each unit to operate.
[0035]
Next, the operation of the display device for displaying the ball dominance rate will be described using the flowcharts shown in FIGS. In the description, it is assumed that the keys are operated in the following order.
[0036]
(1) Set the game time timer and the 30 second timer to the initial state.
At the start of the game, a game time timer and a 30-second timer are set to an initial state in advance. The initial state of the game time timer is “20:00” (20:00) and the initial state of the 30 second timer is “30” (30 seconds), both of which have a countdown configuration.
[0037]
This operation is performed by turning on the timer reset key. When the key is turned on, S43 becomes Y “abbreviation for Yes” (see FIG. 7), and the time contents of the game time timer and the 30 second timer are reset and set to the initial state.
[0038]
(2) Game start
When the game time timer start / stop key is turned on at the same time as the game starts, the determination S40 becomes Y, the game time “20:00” and the 30-second timer “30” are displayed (S41), and the game time timer is simultaneously counted. The trigger for making it apply is applied (S42).
[0039]
Since the game time timer has started counting, the next step S1 (game time timer count determination) is Y, and the subsequent S2 (game time timer start / stop key ON determination) is N “abbreviation for No” (first game time timer) Since the start / stop key is turned on in S40, the game time timer counts the time (S3). Here, in the present embodiment, during the game time timer operation, every time the flow cycle passes through step S2, a countdown process of 2 milliseconds is performed, and the contents of the subtraction time from 20 minutes are stored. This time content becomes a game time timer.
[0040]
Next, it is determined whether or not the game time is over (S4), and since it is determined that the game time has not yet ended, it is determined that N and then the 30-second timer is being counted (S5). Since the 30-second timer has not started, S5 is N, S28 (30-second start / stop key on determination) is N, the left and right team dominance time timer is stopped, and the left and right team indicators are turned off (S29). During the period in which this flow is operating (S1, S2, S3, S4, S5, S28, S29, S1,...), The game time timer is subtracted by 2 milliseconds for each cycle of the flow cycle (S3). The contents are displayed in the game time display area.
[0041]
(3) Turn on the start / stop key of the 30-second timer.
When the game starts and the ball reaches the player of one team, the start / stop key of the 30-second timer is turned on. Actually, since the ball reaches the player's hand almost immediately after the game starts or immediately after the game starts, the game time timer start / stop key and the start / stop key of the 30-second timer are operated with little time.
[0042]
When the 30-second timer start / stop key is turned on, S28 is changed to Y, and a count is applied to the counting operation of the 30-second timer (S33). Then, S1. Y → S2. N → S3 → S4. N then S5 is reached, and now the 30-second timer is counting, so it becomes Y, and S6 (determination of 30-second timer start key / stop key on) is N (first 30-second timer start / stop key on is S28) S7 (30-second reset key-on determination) is N, so in the next S8 (30-second timer count), the minimum unit time (2 ms) is counted down and recorded in the memory. The
[0043]
The next step S9 (determination of 30-second time-up) is N, the subsequent step S10 (determination of whether the right team dominance time timer is in operation) is N, and therefore S17 (determination during the left team dominance time timer count) is also N, S12 (determination of whether the right team key is on) is also N, and S24 (determination of whether the left team key is on) is also N. Every time this flow goes around, a countdown of 2 milliseconds is made in S8 (30-second timer count), and every second, 1 second is subtracted from 30 seconds, and a display is made.
[0044]
(4) When the right team controls the ball
When the ball reaches the right team player immediately after the 30-second timer starts, the measurer presses the right team key. As a result, the right team key-on determination changes to Y, and the right team dominance time timer starts (S12). In the subsequent step S13 (determination during counting of the right team dominance time timer), the right team dominance time timer has not yet started the counting operation, and thus becomes N. In S19, the right team dominance time timer is triggered. At the same time, the right team display is turned on (S20). The lighting of the right team indicator indicates that the ball is controlled by the right team and that the right team control time timer is counting. The subsequent flow passes through S1 to S10, and the right team dominance time timer is counting at S10, so it becomes Y. At S11, the right team dominance time timer is incremented by unit time (2 ms) for each flow and memory Is done.
[0045]
(5) When the left team controls the ball
When the ball is robbed by a player of the opponent team (in this case, the left team) (called turnover), the measurer first presses the 30-second timer reset key with his finger. This key is reset at the moment of pressing (display “30”), and starts counting down from the moment of release. When the 30-second timer reset key is pressed, S7 becomes Y, and the display is turned off simultaneously with resetting the 30-second timer (S16). Subsequently, the right team dominating time timer is stopped and the right team display body is turned off (S29). When the finger is released from the 30-second timer reset key, in the flow of the second cycle, S7 is N, “30” is displayed in S8, and a countdown operation is performed. At S8 for each subsequent cycle, a countdown is performed for each unit time, and the contents are displayed in the 30-second timer display area.
[0046]
The measurer releases the 30-second timer reset key and immediately presses the left team key. As a result, S24 (determination of left team key-on) is Y, the left team dominance time timer is not yet counting, so S25 is N, the left team dominance time timer is started (S30), and the left team display is lit ( S31). Subsequently, it goes to S17 through steps S1 to S10. Since S17 is Y, the unit time is counted for each cycle in the left team dominating time timer, and the accumulated time is stored in memory (S18).
[0047]
(6) When the game is interrupted due to time etc.
If the game is interrupted when the right team is controlling the ball, the game time timer start / stop key is pressed. As a result, S2 (game time timer start / stop key-on determination) is Y, the game time timer and the 30-second timer are stopped, the right team dominance time timer is also stopped, and the right team display is turned off (S32). When the game is resumed and the game time timer start / stop key is turned on again, S40 becomes Y, the contents of the game time timer and the 30-second timer are displayed, and counting is started from the displayed time (S42). That is, the game time is counted down from the time at the stop, and the 30-second timer is counted down from the time at the stop.
[0048]
(7) When the timer is stopped for 30 seconds during the game time timer operation
As described in (6) above, if the game time timer start / stop key is turned on during the game time timer count, the game time timer stops and at the same time the 30 second timer stops, but the 30 second timer start / stop key is The counting operation of the 30-second timer can also be interrupted by pressing. That is, when the 30-second timer start / stop key is turned on, S6 becomes Y, and in S21, the 30-second timer stops counting. At the same time, the left and right team rule time timers are also stopped (S29). According to such a configuration, when the game time timer start / stop key and the 30 second timer start / stop key are pressed almost simultaneously and both are stopped, the 30 second timer is pressed slightly earlier, or Even when the 30 second timer start / stop key is pressed first and the game time timer start / stop key is pressed immediately after that, it can be operated normally.
[0049]
(8) When the 30-second timer expires
In this case, the time-up determination of the 30-second timer becomes Y in S9, the 30-second timer stops counting (S22), both the game time timer and the left and right team time timers stop, and the left and right team display bodies are turned off.
[0050]
(9) When the right or left team key is accidentally pressed
For example, when the right team key is pressed, the right team dominating time timer starts in the flow of S12, Y → S13, N → S19 → S20. If this is an error and the left team key must be pressed correctly, first the right team key is pressed again to stop the right team dominating time timer through the flow of S13, Y → S14 → S15, and After the right team display is turned off, the left team key is pressed, and the left team dominating time timer is started through the flow of S24, Y → S25, N → S30 → S31. If you press the right team key by mistake and then press the left team key in succession, the left and right team control time timers will be activated.
[0051]
(10) When displaying the ball control rate
The calculation of the ball dominance rate is performed while the game time timer is stopped (when the time is taken during the game and the game is interrupted, the time between half times, etc.). When the game time timer is stopped, the left and right team dominance time timers are also stopped. In S1, a determination is made that the game time timer is being counted, and N is determined, and the ball dominance rate is calculated (S34). That is, when the game time timer is stopped, the right and left team dominance time timer is divided into the denominator and the right team dominance time timer or the left team dominance time timer is divided into numerators. Is displayed at a rate of 100 minutes.
[0052]
The display is made by pressing one of the left and right team keys. For example, if the right team key is pressed, S35 and Y are determined to determine whether or not the ball dominance rate is being displayed (S36). If not, the ball dominance rates of both the left and right teams are displayed in the respective display areas (S39). ). When the ball dominating rate is already displayed, it is turned off and the game time is displayed (S37). The same operation is performed when the left team key is pressed (S38).
[0053]
(11) When the game is over
When the game time of 20 minutes is over, S4 (determination of game end) becomes Y, the game time timer, the left and right team control time timer, and the 30 second timer are stopped, and the left and right team display bodies are turned off (S29).
[0054]
In the above embodiment, the ball dominance rate display has been described. However, instead of or in addition to this, an attack count display can be provided. In such a case, as shown in FIG. 9, a right team attack counter 45 and a left team attack counter 46 are provided. That is, when the right team key 9 is turned on, the signal is input to the right team attack number counter 45 via the key recognition unit 25 and the number “1” is added. The left team attack counter 46 operates in the same manner. The contents of these counters 45 and 46 are displayed as the number of attacks in the lower display area 12B of the display unit 3 through the display switching function unit 31. Since the team that normally advances the game has more attacks, it can indicate numerically whether it is superior or inferior.
When displaying the number of attacks of the left and right teams, in the flowchart shown in FIG. 8, in addition to S20 “right team display body lighting” operation, the “right team attack number addition” operation step and S31 “left team display body” In addition to the “lit” operation, it is necessary to provide an “add left team attack count” operation step.
[0055]
The number of attacks for each team is displayed by pressing the right team key or the left team key when the team time and score are displayed on the display section (the game time and 30-second timer time are displayed on the display section) When the right team key or the left team key is pressed, the ball control rate of that team is displayed).
[0056]
【The invention's effect】
As described above, according to the present invention (Claim 1), in a ball game where two left and right teams play, the key operation is performed at the start of the game, the game time is counted by the game time timer, and at the same time, The time each team controls the ball is counted by the left and right control time timers. From the counted ball dominance time of each left and right team, the ball dominance rate of each left and right team is calculated, and the dominance rate is displayed on the display section. You will be able to understand the situation of the battle and predict where you will win and lose. Further, the ball dominance rate is displayed when the game is interrupted, at half-time, etc., so that both teams can use it as a defensive body type and an attack pattern judgment material. The spectators themselves will be able to enjoy themselves by guessing the strategy of both teams based on the difference in the ball dominance rate.
[0057]
  The present invention (claims)1) Has a game time display area and a ball dominance display area for each of the left and right teams on the display unit, and the game time and the ball dominance ratio of the left and right teams are displayed together and correspondingly. It is easy to compare team battle status.Furthermore, when displaying the ball dominance rate of the two left and right teams on the display unit, the display is also used as a score display area for displaying the scores of the two teams. It is configurable and economical.
[0058]
  Furthermore, the present invention (claims)2), The display unit is provided with a team indicator that clearly indicates the dominant team of the ball, so that the attack team and the defensive team can be distinguished.
[0060]
  And the present invention (claims)3) According to the present invention, when this ball dominance rate display device is used in a basketball ball game, the measurer can count the ball dominance time by a simple operation such as a key operation, and the calculation of the ball dominance rate Since it is made and displayed immediately, there is no troublesome work such as measuring the control time or calculating the control rate with a stopwatch or a calculator that has been conventionally performed by a leader or the like. Therefore, efficient practice and appropriate guidance are possible, improving the quality of practice, and contributing to improving practice results in a short period of time. In addition, since the display device is easy to handle, it can be used by non-instructors, for example, players who are practicing, and can be incorporated into practice independently.
