It is a figure explaining a state.

In these figures, the ball judging device of the present invention is a device for judging whether or not a ball (ball) thrown by a pitcher in baseball is a strike and displaying it, and is arranged on the surface of the home base 11. A plurality of sensors 12,... For detecting the height of the passing object, and whether the passing object above the home base 11 is a sphere (ball) is identified based on information from the plurality of sensors 12,. A ball judging means 13, a strike judging means 15 for judging whether or not a strike is made based on information output from the ball judging means 13 and a strike zone inputted for each batter by the strike zone input means 14; A strike button for inputting information output from the strike determination means 15 or a strike (S) or a ball (B) determined by human judgment such as a judge. Le input unit 16, and a display determining means 18 for determining whether a to a display or notification cancellation signal is output from the strike signal input after a specified time counting means 17
And a display 19 for displaying based on the information from the display determining means 18 and a notifier 20 for notifying.

As shown in FIG. 2, the home base 11 is sectioned in a matrix at substantially equal intervals in the horizontal and vertical directions on the surface thereof. The sensor 12 is arranged in each of small rectangular areas that are distinguished by a combination with a vertical section number (A to M). As this sensor 12,
For example, an ultrasonic sensor that emits an ultrasonic wave toward above the home base 11, receives a reflected wave from an object passing over the home base 11, and detects a height (distance) to the object is used. You. That is, the height and the like of an object passing over the home base 11 can be detected by the sensors 12,.

The ball determining means 13 determines the height, traveling direction, speed, etc. of an object passing above the home base 11 detected by the plurality of sensors 12,. It is a means to identify something. For example, if the moving direction of the object is detected in the order of ABC ..., it is determined that the ball is a bat when the batter or the batter stops the bunt, and the MLK ...
Are detected in this order, it is determined that the bat has been swung by the batter, and the speed is determined to be ABC.
In this order, it is determined that the bat is a ball when the speed is high and a bat when the batter stops the bunt when the speed is low.

The strike judging means 15 is a strike zone input means 14 for inputting information on the height when the ball is judged to be a ball (ball) by the ball judging means 13 and data such as height on the strike zone of the batter.
And a means for outputting a strike signal when it is determined that a strike has occurred based on the information from. Generally, according to the rules of baseball, the strike zone is, as shown in FIG. 3, a horizontal line drawn at the midpoint between the upper part of the batter's shoulder and the upper part of the uniform's trousers, and the lower part of the upper line at the knee head. Is different for each height of the batter. Therefore, in the strike zone input means 14, data and the like concerning the height and the like of the batter known in advance are input. The strike judging means 15 judges whether the ball passes through the home base 11 and does not enter the strike zone, and when it is judged that the ball does not pass through the home base 11 and is not detected by the sensors 12,. Since a strike is detected, a strike signal is output only when a strike is detected.

The display judging means 18 is a means for instructing a display on the display 19 or a notification to the alarm 20. The strike ball input means 16 determines whether the strike (S) or the ball (B)
For example, a judge or the like possesses and performs an input operation. Timekeeping means 1
7 is set by the strike signal output from the strike determination means 15 and starts counting time. For example, a signal is output to the display determination means 18 two seconds later, the strike signal is erased, and the pitcher is replaced at the time of pitching practice. The corresponding means. The display determining means 18 is a strike determining means 1
Display or notification is instructed based on the strike signal from the strike ball 5 and the judgment signal from the strike ball input means 16. That is, for example, the output of the strike determining means 15 and the strike / ball input means 16
Is determined, and when they match, the display 19
To display a strike (S) or a ball (B), etc., or when a strike signal is input from the strike / ball input means 16 when a strike signal is not output from the strike determination means 15, or when the reverse occurs. To instruct the referee 20 to re-evaluate the judge, or, if notified to the instructor 20, instruct the display 19 to be re-input from the strike / ball input means 16 or to display the time, The strike signal input from the strike determination means 15 is erased based on the time signal 17.

The display 19 displays the current strike (S) in accordance with the instruction given from the display determination means 18.
, The number of balls (B), and the number of outs (O) are displayed so as to be visually observed. The alarm 20
When a strike signal is input from strike ball input means 16 when strike signal is not output from strike determination means 15, or strike determination means 1
Even when the strike signal is output from the display 5 and the ball (B) information is input from the strike / ball input means 16 and the judgment does not match, the operation is performed by the signal from the display judgment means 18.

According to the ball judging device having the above construction, the object passing on the home base 11 receives the ultrasonic waves emitted from the sensors 12,... The waves are received again and the home base 11 for each corresponding sensor 12,...
The height from the surface to the object is detected. The ball judging means 13 analyzes the information on the height of the object detected for each of the sensors 12,... Corresponding to these passing trajectories, judges the traveling direction, the speed, etc. Ball) is determined. That is, for example, when the traveling direction is ABC... And the speed is a certain speed or more, the ball determining means 13 determines that the ball is a ball (ball).
Outputs detection results related to height, traveling direction, and the like. next,
The strike judging means 13 determines that the height of the ball (ball) output from the ball judging means 13 is within the strike zone based on the data relating to the strike zone of the batter box batter previously input by the strike zone input means 14. Sometimes, a strike signal is output.
When this strike signal is output, the timer 17
When set, the timer starts counting, and outputs an erase signal after a predetermined time, for example, 2 seconds. Next, when the referee inputs the strike (S) from the strike ball input means 16 by the time the erasing signal is output from the timing means 17, the display determination means 18 instructs the display 19 to display a strike display. When the umpire inputs the ball (B), the output of the strike judging means 15 and the judgment of the umpire are judged to be inconsistent. Give instructions. When it is determined that the ball has passed over the home base 11 but does not enter the strike zone, or when the ball has passed other than on the home base 11 and is not detected by the sensors 12,... When the strike signal is not output from 15 and the referee inputs the ball (B) from the strike ball input means 16, a ball is displayed on the display 19. Even if a strike signal is input from the strike determination means 15, if there is no input from the strike / ball input means 16 until an erasure signal is input from the timer means 17, the ball is judged to be a ball by pitching practice and displayed. The strike judgment of the judgment means 18 is deleted. The display determining means 18 stores the strike (S) and the ball (B) for each batter and instructs the display 19 to display the strike (S) and the ball (B), and also instructs the display to indicate the number of outs (O).

Therefore, it is possible to easily know whether or not the ball (ball) thrown by the pitcher is a strike, and it is possible to make an accurate judgment as compared with the result judged by the judge only by visual observation. Excess judgment can be reduced.

In the above-described embodiment, an example has been described in which the ultrasonic sensors 12,... For receiving reflected ultrasonic waves and detecting the height of a passing object are arranged on the surface of the home base 11. Any sensor may be used as long as it detects the height, traveling direction, speed, and the like to the passing object above the home base 11. Further, the strike / ball input means 16 has been described as an example in which the judge or the like manually inputs the strike (S) or the ball (B), but the strike / sound or the ball (B) of the judge is input. Means for detecting and inputting may be used.
