It was very expensive, and there were many problems in utilizing it for general physical education and sports activities. Such a problem will emerge even in a volleyball game whose game rules are similar to those of foot volleyball. That is, for example, the "ball launching device" of Patent Document 1 is configured so that only the horizontal direction in which the ball flies and the inclination angle of the ball that is launched can be adjusted, and the ball is perpendicular to the ground from the upper part of the ball field. You can hone your ball skills such as basketball tossing the dropped aerial ball and tossing it to the ground from high places, using your body such as hands and feet to strike on the opponent's court, volleyball, foot volleyball, etc. could not.

In the volleyball spiking training device disclosed in Patent Document 2, when a ball accumulated inside is supplied from a hopper to an inclined ramp, a discharge coupled to an end of the ramp is generated. The ball is held on the strobe head. When the player hits the ball held by the pair of discharge heads of the discharge strobe with the hand, the ball jumps forward while the discharge head opens, and the ball supplied from the lamp is the discharge head of the discharge strobe. Is held at. However, since the ball distribution device disclosed in Patent Document 2 holds the practice ball supplied from the ramp at the end of the discharge strobe, only the stopped ball can be spiked, and the ball can fly from the air. There was a problem that I could not practice the ball such as hitting or throwing the ball coming out. That is, not only could he not practice basketball but also he could not kick, shoot, or practice tosses with volleyball.

In order to transfer the practice ball, a connecting pipe (wrinkle pipe) 116 having a predetermined diameter is extended from a lower portion of an inflow port 107 formed in the inclined surface 103 of the main body 100. The connecting pipe 116 is connected to an inflow hole 115 formed in an upper portion of a front portion of the hollow body 114 shown in FIG. 4, which constitutes the practice ball launcher 105.

The practice ball that has flowed into the inflow hole 115 of the hollow body 114 is seated at the launch point as shown in FIG. At this time, an inwardly rounded protrusion 114a is formed at the end of the hollow body 114, and the practice ball flowed into the inflow hole 115 is a hollow body that is a projectile unless hit. The phenomenon of flowing out of 114 does not occur. In addition, a sensor provided by a controller (MPU) configured as shown in FIG. 6 for determining the presence or absence of a practice ball is installed at the end of the hollow body 114. Various sensors such as a photo sensor can be used as such a sensor.

The hollow body 114 is coupled to an upper portion of a launch pad 112 which is axially coupled to the lower portion thereof, and the launch pad 114 which is axially coupled to the rotary bracket 110 provided to the lower portion of the hollow body 114 is rotatable on both sides. It is provided in an axially coupled state. More specifically, a rack gear 118 is integrally provided on one side of the shaft-launched launch pad 112, and the drive gear 119 is provided at one side end of the rack gear 118 and the shaft-launched launch pad 112. The tilting motor 117, which is provided in the state of being meshed with each other and connected to the drive gear 119, enables the hollow body 114 to rotate up and down. Further, the rotating bracket 110 is screwed to a rotating plate 128 connected to a rotating shaft of a rotating motor 120 provided below the rotating bracket 110, so that the rotating bracket 120 can be rotated right and left by driving the rotating motor 120.

As described above, the practice ball launcher 105 of the practice ball launching apparatus 100 of the present invention moves the practice ball positioned at the end of the hollow body 114 upward by the horizontal rotation of the rotating bracket 110 and the vertical rotation of the launch pad 112. Or you can fire to the left.

The practice ball that has flowed into the hollow body 114 is fired forward by the operation of the cylinder 130 connected to the rear end of the hollow body 114. As shown in FIG. 5, the piston 132 of the cylinder 130 is inserted inside the hollow body 112, and the striking plate 134 is connected to the end of the piston 132. At this time, the cylinder 132 may be a hydraulic cylinder or a pneumatic cylinder, but it is preferable to use a hydraulic cylinder to fire the practice ball further.

The hydraulic cylinder 132 has a hydraulic inlet and a hydraulic outlet. The hydraulic inlet is connected to the outlet of the nitrogen tank 144 via the hydraulic outlet solenoid valve 150, and the hydraulic outlet is a hydraulic recovery solenoid. It is connected to the hydraulic tank 140 via a valve 146. A hydraulic pump 142 is connected between the hydraulic tank 140 and the nitrogen tank 144, and a hydraulic supply solenoid valve 148 is connected between the hydraulic pump 142 and the nitrogen tank 144. At this time, a nitrogen tube filled with nitrogen is provided inside the nitrogen tank 144, and a pressure gauge for checking the nitrogen pressure of the nitrogen tube is provided. When hydraulic pressure is supplied to the nitrogen tank 114 having such a configuration, pressure is applied to the nitrogen tube in proportion to the supplied hydraulic pressure, so that the internal pressure of the nitrogen tube increases. The internal pressure increase information is provided to the controller MPU.

The operation of the hydraulic circuit configured as described above will be briefly described as follows. In order to cause the piston 132 of the cylinder 30 to protrude forward, the controller drives the hydraulic pump 142 with the supply solenoid valve 148 opened to supply the hydraulic pressure in the hydraulic tank 140 to the nitrogen tank 144. When the amount of hydraulic pressure supplied to the nitrogen tank 144 increases due to continuous pumping, pressure is applied to the nitrogen tube installed therein, and this pressure increase information is provided to the controller. When the pressure sensing information of the nitrogen tube has a preset pressure value, the operation of the hydraulic pump 142 is stopped and the supply solenoid valve 148 is closed. Therefore, it is possible to know that the nitrogen tank 148 is in a state where the hydraulic pressure is filled with high pressure.

When a firing command is input to the controller from the outside (touch screen) or when the firing cycle preset by the program is reached, the controller opens the discharge solenoid valve 150 for a predetermined time. By this operation, when the discharge solenoid valve 150 is opened, the hydraulic pressure with which the nitrogen tank 144 is filled with high pressure is supplied to the hydraulic pressure inlet of the cylinder 130, so that the piston 130 in the cylinder 130 is projected forward. By such an operation, the striking plate 134 attached to the end portion strikes the practice ball placed on the end portion of the hollow body 114 and shoots it forward.

When the controller that drives the discharge solenoid valve 150 to open for a certain period of time opens the recovery solenoid valve 146 and the supply solenoid valve 148 and drives the hydraulic pump 142, the hydraulic pressure filled in the cylinder 130 is changed to the hydraulic tank 140. The piston 132 enters the inside of the cylinder by being recovered.

The controller controls the rotation of the rotary motor 120 coupled to the lower part of the rotary bracket 110 and the rotation of the tilt motor 117 coupled to the side surface of the hollow bracket 114, in addition to driving the hydraulic circuit described above. It can be adjusted to face left or right or up and down.

As described above, the practice ball launching device 100 is provided with the touch screen TS on the outside of the main body 102, and the touch screen TS is connected to the controller MPU built in the main body 102. The data input through the TS causes the controller MPU to control the operation of each operating element provided inside the main body 102. That is, the controller starts controlling the operations of the tilt motor 117, the rotary motor 120, the hydraulic pump 142, and the various solenoid valves 146, 148, 150 inside the main body 102.

The practice ball launching device 100 can be operated in a manual setting mode and a motion sensing mode under the control of the controller MPU. In the manual setting mode, the user uses the touch screen TS installed on the main body 102 to select one of the exercise modes (penalty kick, corner kick set play, goro shoot, volley shoot ball, heading shoot ball, and sub ball). One or a mixed form of these) and a firing cycle (for example, a ball is fired about every 15 seconds), and each time the fire button is pressed, a practice ball is fired at the ball stadium 10, a goro-corner kick, volley. When one or more of shoot corner kick, heading shoot corner kick, sub-ball, or a mixed mode thereof is selected and the firing button is pressed, the hollow body 114 is automatically fired according to the selected motion mode. The angle (tilt motor 117 and rotary motor 120) is adjusted, and practice balls are continuously fired at a preset cycle. At this time, although the example in which the firing button is provided on the touch screen TC has been described, it can be provided on the remote controller carried by the soccer player by using a normal remote controller.

Manual/Automatic Setting Mode of Practice Ball Launching Device 100 When the practice ball launching device 100 is operated, the launcher MPU checks the pressure in the nitrogen tank 144 in step S1 to set the piston 132 of the cylinder 130 in advance. It is searched that the pressure is such that it can eject (discharge) at the set speed. If the pressure of the nitrogen tube in the nitrogen tank 140 does not reach the preset pressure, the controller opens the recovery solenoid valve 146 and the supply solenoid valve 148 via the solenoid valve driving unit SOD in step S6, The hydraulic pump 142 is driven. Therefore, the hydraulic pressure in the cylinder 130 is collected in the hydraulic tank 140 and then supplied to the nitrogen tank 144. When the oil pressure is continuously supplied to the nitrogen tank 144, the pressure applied to the nitrogen tube installed therein increases to reach the set pressure.

If it is determined that the pressure of the nitrogen tank is the set pressure in step S2, the controller MPU closes the recovery solenoid valves 146, 148 and the discharge solenoid valve 150 through the solenoid valve driver SOD in step S3. , S4, it is searched whether the fire button of the touch screen or the remote control is pressed. When it is determined in step S4 that the fire button is pressed, the controller MPU opens the discharge solenoid valve 148 for a preset time T in step S5. At this time, the hydraulic pressure with which the nitrogen tank 144 is filled with high pressure is supplied to the inlet of the cylinder 130 at high speed through the discharge solenoid valve 148 due to the expansion of the compressed nitrogen tube.

Therefore, the cylinder 130 causes the piston 132 positioned inside thereof to project forward due to the hydraulic pressure flowing in at a very high pressure, and the striking plate 134 connected to the end of the piston 132 due to the forward projection of the piston 132, A practice ball placed at the end of the hollow body 114 is hit and fired forward. At this time, it is judged that the launch angle of the practice ball launcher 105 located in the space of the main body 102 of the practice ball launching device 100 is set by the controller controlling the tilt motor 117 and the rotary motor 120 described above. It

The controller MPU that has executed the step S5 opens the recovery solenoid valve 146 and the supply solenoid valve 148 via the solenoid valve drive unit SOD in the step S6, and then drives the hydraulic pump 142 in the step S7. The nitrogen tank 142 is filled with hydraulic pressure.

If the launch button displayed on the touch screen TS is not selected in step S4, the controller MPU determines that the hollow body 114 of the practice ball launcher 105 is in accordance with the mode set in step S8. After adjusting the horizontal and vertical angles and the firing interval, the step S5 described above is executed. The mode set in the step S8 means the automatic firing mode and the camera mode.

If the setting mode is the automatic firing mode in step S8, the controller MPU drives the rotary motor 120 and the tilt motor 117 by inputting the direction setting keys (vertical and horizontal) from the touch screen to practice. The launch direction of the ball launcher 105 is set, and the practice ball is launched by operating the cylinder 130 of the hydraulic device via the solenoid valve drive unit SOD at preset time intervals. When the setting mode is determined to be the camera mode in step S8, the controller MPU controls the operation of the practice ball launching device 100 in the procedure of FIG. 8, and in the case of the stop mode in step S8, what operation is performed. There isn't.

Motion detection mode

In the motion detection mode, after setting the firing direction by the camera 1CAM1 and the camera 2CAM2 set from the side surface of the main body 102, the practice ball is fired by the camera 1CAM1 and the camera 2CAM2 according to the movement of the player in front or side. It is a thing.

Referring to FIG. 8, the controller MPU searches whether the current mode is the operation mode of the camera in step S104. As a result of the search, if it is not the operation mode of the camera, the process jumps to step S17 to shoot the practice ball according to the manual/automatic mode operation as described above.

When it is determined in step S12 that the camera is in the operation mode, the controller MPU receives the video signals captured by the cameras 1CAM1 and 2CAM2 installed from the side surface of the main body 102 in step S11, In step S12, the movement of the player in front of or in the side of the practice ball launching device 100 is detected. The controller MPU, which has detected the player's movement, grasps the detected player's location, controls the tilt motor 117 and the horizontal motor 120 in step S13, and adjusts the vertical angle and the horizontal angle to practice. The launch angle of the ball launcher 105 is set.

Thereafter, the controller MPU analyzes the video signal transmitted from the camera 1CAM1 and the camera 2CAM2 in step S14 to analyze the motion of the subject, and the motion of the player is a preset motion in step S15. Search whether or not. For example, a search is made as to whether or not the player has raised his arms. Such a search can be easily performed by comparing the video of the frame one second before and the video of the current frame.

If it is determined in step S15 that the player movement of the video signal received via the camera 1CAM1 and camera 2CAM2 is a preset movement, the controller MPU sets the solenoid valve driver SOD in step S16. As described above, the striking plate 134 installed on the front portion of the piston 132 of the cylinder 130 hits the practice ball so that the practice ball is shot toward the subject as described above.

According to the operation mode of the practice ball launching device 100, the practice ball launcher 105 directs any one of the openings so that the practice ball launched toward the player is When hitting (for example, a foot, a hand, etc.), the ball is blown to the touch line or the goal line side, or rolls, and finally falls on the floor of the ball stadium.

In the above embodiments, the driving device of the practice ball launcher 105 is a hydraulic cylinder, but a person skilled in the art who understands the specification of the present invention may use a pneumatic cylinder. You can

FIG. 9 shows a specific configuration of the ball collecting device according to the embodiment of the present invention, in which the ball collecting device is installed on one side of the floor of the ball playing field 10. At this time, the ball field must be understood as a concept including a soccer field, a basketball court, a volleyball court, a foot volleyball court, etc., where a ball game can be played, as described above. The practice ball that has fallen on the ball playing field 10 is formed so as to be inclined from the center to both sides (θ2) so as to roll from the half line (or half line) toward the goal line (or end line). The ball collecting device 200 shown in FIG. 9 is installed in the transfer groove 14 formed in the rear part of the goal line or the end line of the ball playing field 10 as shown in FIG.

The transfer groove 14 is formed at one corner and is inclined downward toward the other corner or toward the center. Therefore, the practice ball falling from the half line HL or the half line to the ball field 10 inclined to the goal lines or the end lines on both sides rolls in the direction of the goal line from the half line HL and finally reaches the transfer groove 14. Collected in. The practice balls collected in the transfer groove 14 roll to the lower end side of the cylindrical collecting pipe, that is, the ball collecting device 200, and the practice balls flowing into the lower end side of the ball collecting device 200 are the ball collecting device 200. Flows into the lower end gate G of the.

As shown in FIG. 9, when the recovery motor 206 installed on the upper part of the ball recovery device 200 is rotated, the rotation shaft 208 connected thereto is rotated. At this time, a spiral screw 210 having a pitch (for example, 220 mm) wider than the diameter of the practice ball by about 1 cm is formed on the outer peripheral surface of the rotary shaft 208. At this time, the distance r1 between the rotating shaft 208 and the inner surface of the ball collecting device 200 is formed to be smaller than the diameter r2 of the practice ball by about 2 mm to 3 mm. Therefore, when the rotating shaft 208 is rotated, the practice ball flowing into the lower end gate G of the ball collecting device 200 is transferred to the upper part along the screw transfer device 212 including the rotating shaft 208 and the spiral screw 210. .. At this time, the distance r2 between the rotary shaft 208 and the inner surface of the ball collector 200 is formed smaller than the diameter r1 of the practice ball, and the practice ball is slightly distorted, so that the practice ball can be transferred to the upper part smoothly.

In the transfer groove 14 in the front portion of the gate G of the ball collecting device 200, a vibration plate 214 that is vibrated in the length direction by the rotation of the vibration motor 216 is embedded. During the ball collecting operation, the vibration motor 216 rotates simultaneously with the collecting motor 206 so that the practice balls collected at the end of the downwardly inclined transfer groove 14 are smoothly moved to the gate G side of the ball collecting device 200. To enter.

The practice ball transferred to the upper part of the screw transfer device 212 of the ball collector 200 is discharged to the ball discharge pipe 202 by the rotation of the spiral screw 210. The practice ball discharged through the ball discharge pipe 202 is configured as shown in FIGS. 1 to 8 and is above the ball receiver 104 of the practice ball launching device 100 installed adjacent to the ball collector 200. It is put in it through the opening.

In the above embodiment, the sphere collector 200 has the rotating shaft 208 of the spiral screw 210 installed inside the cylindrical collecting pipe 204, and the spiral screw 210 and the inner wall of the cylindrical collecting pipe 204 are arranged along the inner wall of the cylindrical collecting pipe 204. Although the configuration in which the screw is transferred to the upper part is disclosed, a screw transfer device having a structure equivalent to this is applicable.

For example, two poles vertically erected on both sides of a short distance of about 1 mm to 2 mm from the diameter r2 of the practice ball in the direction of the gate into which the practice ball rolls in from the rotary shaft 208 of the spiral screw 210 ( It can be considered to install a pole). When the practice ball rolls into the gate of the ball collector constructed according to the other embodiment constructed as above, the practice screw is positioned between the rotary shaft 208 and the two poles, and the spiral screw rotates. Then, the practice ball is vertically moved along the rotation axis and the two poles to be inserted therein through the upper opening of the ball receiver 104 of the practice ball launching device 100.

In the configuration of FIG. 9 described above, the sphere discharge pipe 202 installed on the upper part of the sphere collector 200 is rotatably installed on the upper part of the cylindrical collection pipe 204, as indicated by “R” in the drawing. By doing so, the ring gear or the like can be manually rotated or rotated by a motor, and can be designed to automatically rotate by power.

FIG. 10 is a detailed configuration diagram of the ball dispenser 300 according to the present invention, which is installed on a pillar 25 standing vertically on the floor surface of the ball playing field 10 to drop a practice ball on the ball playing field 10 or horizontally. It is useful for practicing foot volleyball, volleyball spiking, basketball three-point shots, etc. by flying the practice ball in any direction and distributing the ball towards the players in the ball field 10.

Referring to FIG. 10, the ball distributor 300 has a housing 301 coupled to one side of an upper portion of a pillar 250. One side of the upper portion of the housing 301 is opened, and a sphere storage 304 is formed therein, and the inside of the sphere storage 304 is separated by a partition 308 to form a discharge space 306. A floor surface 305 of the ball storage 304 is formed to be inclined downward toward the discharge space 306, and a discharge pipe 316 for discharging a practice ball is rotatably coupled to the floor surface of the discharge space 306. An opening is formed.

The rotation opening/closing plate 310 opens and closes a discharge hole formed in a lower portion of the partition wall 308 according to the rotation of the opening/closing motor 302 so that the practice ball stored in the ball storage space 304 is discharged from the discharge hole. ..

An upper end portion of the discharge pipe 316 is inserted into an installation space provided in a lower portion of the housing 302, and a rack gear of a straight bevel gear 318 is coupled around the installation space. A drive gear of the straight bevel gear 318 is coupled to a rotary shaft 322 of a swing motor 320 fixed in the installation space, and is coupled to the opening/closing motor 302, the swing motor 320, and a controller (MCU) 324. The discharge pipe 316 is configured to be inclined downward, and a vertical drop outlet 316a formed downward and a horizontal outlet 316b formed inclined in the horizontal direction are formed at ends of the discharge pipe 316. The ball that has flowed into the 316 is discharged to the vertical drop outlet 316a or the horizontal outlet 316b by a damper 316c connected between the drop outlet 316a and the horizontal outlet 316b.

The damper 316c opens one of the vertical drop outlet 316a and the horizontal outlet 316b by a damper driver 316d including a motor. When the damper driver 316d is not used, a normal manual damper (switch) that is manually operated can be used. When the damper driver 316d is used, the damper driver 316d is controlled by a controller 324 which receives a remote control signal from a remote controller.

For example, when the damper driver 316d drives the damper 316c in the vertical direction, the vertical drop outlet 316a is opened and the horizontal outlet 316b is closed, so that the practice ball discharged from the discharge pipe 316 falls directly downward. To be done. On the other hand, when the damper driver 316d drives the damper 316c in the horizontal direction, the drop outlet 316a is closed and the horizontal outlet 316b is opened, so that the practice ball discharged from the discharge pipe 316 is It is dropped while flying in the horizontal direction through the horizontal exit 316b.

When the open/close motor 302 is rotated once by the control of the controller 324 shown in FIG. 10, the rotary open/close plate 310 axially coupled to the rotary shaft 312 of the open/close motor 302 is opened and then closed for one practice. The ball is made to drop the practice ball directly from the upper part of the floor (coat) of the ball field 10 through the vertical drop outlet 316a provided at the end of the discharge pipe 316, or through the horizontal outlet 316b. , After flying horizontally, the player can hit the ball falling in various directions from above, or practice by shooting flying practice balls and shooting them so that they fall on the floor (coat) of the ball field 10. be able to. Therefore, the player falls from the upper part of the floor surface (coat) of the ball stadium 10 directly below, practice the practice ball flying from the horizontal direction by practicing a spike attack that hits hard with a hand, or practice by kicking with a foot. Can be diverse.

Also, since the direction of the end of the discharge pipe 316 can be adjusted by rotating the swing motor 320 to adjust the falling direction of the ball, it is possible to practice in various places.

The controller 324 transmits/receives data to/from the controller 324 of the practice ball launching device 100 in a wired or wireless manner, receives a ball distribution control signal, and controls the opening/closing motor 302 and the swing motor 320, or a remote controller. It can be controlled independently. When the remote controller is controlled by a remote controller, the controller 324 is driven by a remote control signal transmitted from the remote controller to drive the opening/closing motor 302 and the swing motor 320 so that the practice ball accommodated in the ball retainer 304 is placed on the floor of the ball playing field 10. Can be dropped on the (coat).

For example, it is possible to consider installing a movable wheel or the like under the goal post 12. That is, in a ball game field, the soccer practice device 1 is installed in a futsal ball field that can be easily configured indoors, and is usually used as a futsal ball field so that an individual or several people can practice soccer. It is preferable to freely move the goal post 12 so that it can be easily changed as a practice field.

Conversion mode of soccer goal score when practice ball passes the goal post

When the practice ball passes through the goal post 12 shown in FIG. 11, it is detected by the sensor of the ball sensing gate BSG shown in FIG. Each sensor of the ball sensing gate BSG includes a light emitting element array (XL1 to XL4, YL1 to YL10) and a light receiving element array (XP1 to XP4, YP1 to YP10) installed on the opposite side corresponding thereto. To be done.

FIG. 13 shows an example of the ball sensing gate BSG, in which the soccer goal post is divided into 40 areas, the score is determined for each area, and the area is for detecting that the practice ball passes. is there. Arabic numerals “0 to 10” written inside the ball sensing gate BSG of FIG. 13 indicate the scores for each area.

Referring to FIG. 13, the ball sensing gate BSG coupled to the rear portion of the goal post 12 includes light emitting element arrays (XL1 to XL4, YL1 to YL10) installed on the left and upper sides of the ball sensing gate BSG. It shows that the light receiving element arrays (XP1 to XP4, YP1 to YP10) are installed on the right side and the lower side of the BSG. At this time, the heights of the soccer goal posts 12 (the light emitting element arrays (XL1 to XL4) and the light receiving element arrays (XP1 to XP4) installed on the left and right sides of the ball sensing gate BSG manufactured in the shape of a square frame ( (2440 mm) is equally divided into four and installed at intervals of 610 mm, and the light receiving element arrays (XP1 to XP4 and YP1 to YP10) installed on the upper side and the lower side of the ball sensing gate BSG are The horizontal length (7320 mm) of the soccer goal post 12 is divided into 10 equal parts, and the soccer goal posts 12 are installed at intervals of 732 mm.

At least three light emitting elements are installed at equal intervals inside each of the light emitting element arrays (XL1 to XL4, YL1 to YL10) and correspond to the light emitting element arrays (XL1 to XL4, YL1 to YL10). Then, at least three light receiving elements are installed at equal intervals inside each of the light receiving element arrays (XP1 to XP4, YP1 to YP10) installed on the opposite side. Each of the light emitting element arrays (XL1 to XL4, YL1 to YL10) configured as described above is driven to emit light according to drive signals of the X axis and the Y axis, and the light receiving element arrays (XP1 to XP4, YP1 to YP10). ) Senses the light source of the light emitting element array (XL1 to XL4, YL1 to YL10).

In the above-described embodiment, it is described that three elements are installed inside the light emitting element arrays (XP1 to XP4, YP1 to YP10) and the light receiving element arrays (XP1 to XP4, YP1 to YP10), but the sensing sensitivity It is self-evident that a larger number can be installed in order to increase

FIG. 14 shows a practice of driving the optical element arrays (XL1 to XL4, YL1 to YL10) of the ball sensing gate BSG shown in FIG. 13 and reading the outputs of the light receiving element arrays (XP1 to XP4, YP1 to YP10). It shows the structure of the score counter SCNT which detects whether the ball has passed through any part of the goal post 12 and displays the converted score according to the ball speed of the practice ball detected by the speed gun SG. Is.

Referring to FIG. 14, the score counter SCNT may include light emitting element arrays XLi and YLj (where i is “1 to 4”, j is set on the X axis and the Y axis of the ball sensing gate BSG according to the light emission control signal). Is an integer of “1 to 10”), and the light emitting drive units LD1 and LD2 for driving the ball sensing gate BSG and the light emitting device arrays XLi and YLj of the X axis and the Y axis of the ball sensing gate BSG. The ball sensing is performed by driving the optical receivers PR1 and PR2 that read the outputs of the light receiving element arrays XPi and YPj that receive the light sources (or infrared rays) projected from the light emitting element arrays XLi and YLj, and the light emission drive units LD1 and LD2. An optical receiver PR1 for reading the outputs of the light-receiving element arrays XPi, YPj installed on the X-axis and Y-axis of the ball sensing gate BSG by lighting the light-emitting element arrays XLi, YLj installed on the X-axis and Y-axis of the gate BSG. , PR2, the ball passing area of the goal post 12 is determined, and then the impact signal and the goal post 12 output from the impact sensor IS (Impact sensor) installed in the go post 12 or the ball sensing gate BSG. A score controller SCNT for converting a score according to the output of the speed gun SG installed behind the display unit and a display DISP for externally displaying the score converted by the score controller SCNT are included. In the embodiment of the present invention, it is described that the light emission drive units LD1 and LD2 and the optical receivers PR1 and PR2 are provided. However, the score controller SCNT integrally drives the light emitting element arrays XLi and YLj, and the light receiving element array. It may not be provided when the outputs of XPi and YPj are integratedly read.

With reference to FIG. 13 and FIG. 14, a score conversion operation when the practice ball passes through the goal post will be described.

When the soccer practice device 1 is operated, the score controller SCNT shown in FIG. 14 provides a light emission control signal to the light emission drivers LD1 and LD2, and the X axis of the ball sensing gate BSG shown in FIG. And all the light emitting element arrays XLi and YLj installed on the Y axis are turned on. At this time, all the light emitting elements in the light emitting element arrays XLi and YLj installed on the left side of the X axis and the upper side of the Y axis are turned on, and the light emitted by the lighting is turned on the right side of the X axis and the lower side of the Y axis, respectively. It is displayed on the corresponding light receiving element arrays XPi and YPj. At this time, the light receiving element arrays XPi, YPj receive (sense) the light projected on the light emitting element arrays XLi, YLj, and input corresponding sensing signals to the optical receivers PR1, PR2.

Normally, since the ball does not enter the goal post 12, the light projected from the light emitting element arrays XLi, YLj installed on the left side of the X axis and the upper portion of the Y axis are not blocked and the light receiving element array XPi, Provided to YPj. Therefore, when the ball does not enter the goal post 12, the signals sensed by the light-receiving element arrays XPi and YPj are all the same, and the sensed signals are sent to the score controller via the optical receivers PR1 and PR2. Offered to SCNT.

The score controller SCNT senses whether to intercept the sensing signals of the light receiving element arrays XPi and YPj received through the optical receivers PR1 and PR2, and which area of the goal post 12 the ball has passed. To determine. When the ball has not passed the goal post 12, the sensing signals of the light-receiving element arrays XPi and YPj all remain in the activated (logical “high”) state, and the goal is not recognized.

When the practice ball shot by the practitioner passes through the “A” area in FIG. 13, the light projected from the light emitting element arrays XL1 and YL1 is momentarily blocked by the practice ball passing through the “A” area. Only the outputs of the two light-receiving element arrays XPi, YPj are momentarily deactivated (logic "low"), which immediately leads to the score controller SCNT via the optical receivers PR1, PR2. Provided to. At this time, the score controller SCNT senses that the outputs of the two light receiving element arrays XPi and YPj are inactive, recognizes that the practice ball has passed the area “A” of FIG. 13, and is programmed. “10” points are given according to the content of the score.

After that, the score controller SCNT reads the speed information of the practice ball sensed by the speed gun SG installed at the rear of the goal post 12, and then the weighted value based on the speed information is used as the goal post passage point “10”. The practice ball passing area and the goal post passing points are displayed on the display device DISP, and it is possible to determine which part the ball kicked by the practitioner has been scored in. Let me check. Therefore, the practice can be more interested in the practice. The weighted value is 1 when the speed of the ball is a strong shot (60 km/h) or more, and 0.5 when it is less than that, even if the ball passes through the same area. , Different points according to the speed of the ball.
