Description

  The present invention relates to a swing practice device for practicing a swing of a swing tool such as a golf club.

  Conventionally, various apparatuses for practicing a swing such as a golf club have been proposed. For example, FIGS. 6 and 7 are diagrams showing a golf shot practice machine proposed in Japanese Patent Laid-Open No. 08-117379 (Patent Document 1). In the conventional golf shot training machine shown in FIGS. 6 and 7, a plurality of photoelectric sensors are used, the speed of the club head at the time of shot, the face direction of the club head at the time of shot (face surface angle), The club head detects a left-right bias with respect to the shot direction, and displays the detection result. Below, the content of the golf shot practice machine of the said gazette is demonstrated.

In this conventional golf shot practice machine, as shown in FIGS. 6 and 7, photoelectric sensors 1a, 1b, 2a, 2b, 3a, 3b, 4a, 4b, 5a, 5b, 6a are attached to a base (mat) 12 to which the sensor is attached. , 6b are attached. These sensors are transmissive photoelectric sensors, 1a, 2a, 3a, 4a, 5a, and 6a are light emitting sides, and 1b, 2b, 3b, 4b, 5b, and 6b are light receiving sides. The light source on the light emitting side and the external output that outputs the light receiving / shading state on the light receiving side are built in the sensor amplifier. The light source generates light modulated in a pulse shape so as not to be affected by disturbance light such as a fluorescent lamp. As the external output, one that reacts in about 20 to 30 μs is used so that the light shielding by the club head 9 a during the swing of the golf club 9 can be detected.
The photoelectric sensors 1 a-1 b and 2 a-2 b detect left and right deviations with respect to the shot direction of the club head 9 a immediately before the golf ball 8 is shot. The attachment positions are separated from each other by the same distance from the center line 13 parallel to the swing direction and passing through the center of the golf ball 8. The interval between the photoelectric sensors 1a and 2b or the photoelectric sensors 1b and 2a is larger than the diameter of the golf ball 8 and smaller than the width of the club head 9a. The photoelectric sensors 3a-3b and 4a-4b detect the shot speed of the club head 9a. The mounting position is perpendicular to the swing direction, the photoelectric sensor 4a-4b is installed in front of the golf ball 8 so that the optical axis 4c is formed, and the photoelectric sensor 3a-3b is installed as close as possible to the photoelectric sensor 4a-4b. . The photoelectric sensors 5a-5b and 6a-6b detect the face direction of the club head 9a. The mounting position is such that the optical axes 5c and 6c are opened at the same angle on both sides from the center line 13, and the sensor is set so that the intersection of the optical axes 5c and 6c can be in front of the golf ball 8 on the center line 13. Install. All the sensors are set at a height at which the club head 9a passes immediately before the golf ball 8 is shot by the swing motion of the golfer 10 and are attached at positions where the swing motion is not hindered.

The head speed of the club head 9a is displayed by the head speed display means 11a. As an example of realization of the means, a reference clock generator, a counter, a circuit for setting the distance of the photoelectric sensors 3a-4b, a division circuit, and a numeric display are provided, and the sensor external output signal 3d from the point of time when the sensor external output signal 3d is cut off The clock pulses generated from the reference clock generator are counted by the counter until the output signal 4d is cut off, the distance of the photoelectric sensors 3a-4b is divided by the count value by the division circuit, and the result is displayed in numbers. By displaying on the instrument, speed display can be realized. The shot direction of the club head 9a is displayed by the shot direction display means 11b. As an example of means realization, display in the shot direction is made from four signal patterns using the sensor external output signals 1d, 2d, 5d, and 6d. The shot direction is displayed by turning on the light emitting diodes in the middle, left, and right directions. The timing of inputting the sensor external output signals 1d, 2d, 5d, 6d is limited to the time when the club head 9a passes between the optical axes 3c-4c in order to detect the state immediately before the shot of the golf ball 8. As an example of display in the shot direction after the sensor external output signal is detected, if both 1d and 2d are shielded and 5d and 6d are shielded simultaneously, the center of the golf ball 8 immediately before the club head 9a shots the golf ball 8 And the face surface faces the direction of the center line 13. As a result, the shot direction is displayed by turning on the light emitting diode. If both 1d and 2d are shielded and 5d is shielded first, the club head 9a passes through the center of the golf ball 8 just before the golf ball 8 is shot, and the face surface is the center line 13 in the shot direction. Is facing to the left. As a result, the shot direction is displayed by turning on the light emitting diode in the left direction. The shot direction may be displayed in a pattern such as middle, left, right, etc., or the detection states of the sensor external output signals 1d, 2d, 5d, 6d may be displayed as they are.
Whether the current shot is valid for displaying the head speed and the shot direction is determined by the shot valid / invalid determining means 11c. In order to determine the validity / invalidity of the shot, the club head 9a within a predetermined time from a predetermined reset operation (see the reset means 11e in FIG. 7) in the sensor external output signal 1d or 2d, 3d, 4d, 5d, 6d. If there is something that has not been detected, it is determined that the shot is invalid, and this is notified by the reporting means 11d such as a buzzer so that the golfer 10 can understand this. When all the sensor external output signals 1d, 2d, 3d, 4d, 5d, 6d detect the passage of the club head 9a within a predetermined time from the reset operation, it is determined that the shot is valid, the above-described head speed display, and the shot direction Is displayed.
JP-A-8-117379

  The conventional golf shot practice machine described with reference to FIGS. 6 and 7 does not limit the practice place, so that the user can practice golf shots using a real golf club and golf ball at home or the like. . However, since the conventional golf shot practice machine described in FIGS. 6 and 7 uses a real golf ball, it is necessary to provide a net or the like for capturing the real golf ball. It does not make it possible to practice swing anywhere.

  The present invention has been made paying attention to the problems of such a conventional swing practice device, and allows a user to easily practice swings such as golf clubs anywhere, and to play a real ball. It is an object of the present invention to provide a swing practice device that can practice swing while feeling a sense of realism similar to that in use.

In order to solve the above-described problems, a golf club and other swing practice device according to the present invention is provided at a predetermined position in the space in front of the user, using the actual swing tool that the user uses for real ball games. Swing target for displaying a swing target image that can be visually recognized by the user as a swing target / target and a part of the real swing tool can pass through the swing target image. Based on video display means, swing state detection means for detecting a swing state when the user swings the real swing tool with respect to the swing target video, and output from the swing state detection means, The display of the swing target image is stopped at the time of a shot to the swing target image during the user's swing. Swing target video display control means for controlling the swing target video display means (this video display control means is the swing target video at the moment of impact on the swing target video (simultaneously with the generation of a hitting sound to be described later). And display again after a few seconds), and based on the output from the swing state detection means, a hit for outputting a predetermined ball hitting sound at the time of a shot on the swing target video during the swing of the user A sound output unit; and a swing state display unit for displaying a state of the user's swing or a shot content by the swing based on an output from the swing state detection unit. is there.
In this specification, the “swing target image” is a target / target when the user swings a real swing tool, and is displayed in a space in front of the user, and the real swing tool is displayed. It can pass through it (because it is an image displayed in space, a real swing device can pass through it). This swing target image is most desirable if it can be “an image of a real ball” or an image of a substantially spherical object similar to this, but it is not always necessary to be such an image and the user can An image that can be visually recognized as a target / object in the space is sufficient. Therefore, the shape of the swing target image is not necessarily spherical, and may be, for example, an elliptical shape or a substantially spherical shape with a perceived blurry outer contour.

  In the swing practice device such as a golf club according to the present invention, a ball placing tee formed by an elastic member is positioned below the position where the swing target image is displayed, and when the swing is performed by the user. It is desirable to arrange it at a position where it is hit with the swing target image.

  In the swing practice device such as a golf club according to the present invention, the swing target image display control means may be configured such that a real swing device swung by a user is added to the swing target image based on an output from the swing state detection means. When there is no apparent contact (when the actual swing tool has not passed through the swing target image), the swing target image display means is configured to continue the display without stopping the swing target image. The hitting sound output means is based on the output from the swing state detection means when the real swing tool that the user has swung does not seem to contact the swing target image (real thing). When the swing device does not pass through the swing target image), the ball hitting sound One that does not output, it is desirable.

  Further, in the swing practice device such as a golf club according to the present invention, a hitting sound database is provided for recording the state of each swing by the user and the hitting sound of each ball in association with each other, and the hitting sound output Based on the output from the swing state detecting means, the means extracts the striking sound corresponding to the swing state by the user at that time from the striking sound database, and outputs the extracted striking sound. desirable.

  Furthermore, in the swing practice device such as a golf club according to the present invention, the swing state detecting means is configured to detect a correct shot, a left hook OB, and a right slice OB with respect to a user's swing as a detection target (and a shot content by the swing). Any one of at least three types of results (shot contents) is estimated and determined, and the hitting sound database includes at least three types of results of a correct shot, a left hook OB, and a right slice OB ( The estimation / determination result = shot content), the ball hitting sound at the time of the correct shot, the ball hitting sound at the left hook OB, and the ball hitting sound at the right slice OB are recorded in association with each other. The hitting sound output means outputs the output from the swing state detection means. And Zui extracts striking sound corresponding to the results inferred-determined for swing user at that time from the striking sound database, and outputs the extracted striking sound, it is desirable.

  In the present invention, since the swing target image display means displays the swing target image such as the ball image in the space, the golf ball is captured like the conventional golf shot practice machine using a real golf ball. There is no need to install a net for the user, and the user can easily practice swinging a real swing device such as a golf club anywhere. Further, particularly in the present invention, when the user swings the swing target image with a real swing tool by the swing target image display control means and the hitting sound output means, the swing target image is taken out of space at the moment of the shot. Since a predetermined ball striking sound is output while erasing, the user can obtain a sense of realism similar to using a real ball at the time of a shot.

  In the present invention, the ball placing tee formed by an elastic member is hit with the swing target image at a position below the position where the swing target image is displayed, when the user swings. When it is arranged at a position where it can be obtained, in addition to stopping the display of the swing target image and outputting the ball hitting sound, the user feels the feel of hitting the tee when shooting by the user. This makes it possible to enhance the sense of presence when shooting.

  Further, in the present invention, when the real swing tool that the user swings does not apparently contact the swing target image (the real swing tool has not passed through the swing target image), the swing It is desirable to display the target image as it is without erasing it, and not to output the ball hitting sound. In this case, if the swing device image is swung by the actual swing tool that the user swings, the swing target image is displayed as it is and no hitting sound is output. The result is the same as when you did it, and you can enhance the sense of reality.

  Further, in the present invention, at the time of a shot by the user, based on the output from the swing state detection means, a striking sound corresponding to the result of the guess of the swing by the user at that time is extracted from the striking sound database, and the extraction When the hitting sound is output, the ball hitting sound corresponding to the user's actual swing prediction result (for example, correct shot, left hook OB, or right slice OB) at the time of shot by the user (for example, correct) A ball hitting sound at the time of a shot, a ball hitting sound at the time of a left hook OB, or a ball hitting sound at the time of a right slice OB) can be output.

  The best mode for carrying out the present invention is a mode as described in Example 1 below.

  FIG. 1 is a view for explaining an outline of a golf club swing practice apparatus according to Embodiment 1 of the present invention. In FIG. 1, 9 is a golf club, 9 a is a head of the golf club 9, 20 is a user, 21 is a swing practice device that constitutes the first embodiment, 22 is a sensor built-in mat (base) that constitutes the first embodiment, Reference numeral 23 denotes a swing target image displayed in the space by the swing practice device 21. The sensor built-in mat 22 is configured in substantially the same manner as the base 12 described above with reference to FIGS. 6 and 7, and the sensor built-in mat 22 includes the same photoelectric sensors 1 a, 1 b, 2 a, as described in FIGS. 2b, 3a, 3b, 4a, 4b, 5a, 5b, 6a and 6b are built in predetermined locations. Each of these sensors is electrically connected to the swing practice device 21. Moreover, in the present Example 1, the below-mentioned swing object image | video is displayed on the position of the golf ball 8 of FIG.

  Next, FIG. 2A is a diagram showing an appearance of the swing practice device 21. In FIG. 2 (a), 24 is a display unit disposed substantially at the center of the front surface of the swing practice device 21, and 25a and 25b are speakers disposed on the left and right sides of the display unit 24 on the front surface of the swing practice device 21, respectively. , 26a and 26b are laser beam irradiation units respectively disposed on the sides of the speakers 25a and 25b on the front surface of the swing practice device 21. The display unit 24 may be constituted by a liquid crystal display device, for example, but in the first embodiment, a simplified display using LEDs (light emitting diodes) is used for cost reduction.

The laser light irradiation units 26a and 26b irradiate the visible light laser so that the colored visible light lasers to be irradiated intersect each other at a predetermined position in the space. As shown in FIG. 2B, the visible light lasers 27a and 27b irradiated from the laser light irradiation units 26a and 26b intersect at a predetermined position (space) on the sensor-containing mat 22. The visible light lasers 27a and 27b intersect each other while being swung within a predetermined angle range at a high speed to form a plurality of intersections. As a result, the plurality of intersections are accumulated in a predetermined space. Due to the afterimage phenomenon, for example, the swing target image 23 having a substantially spherical shape or a shape similar to the spherical shape appears to float in the air.
In the first embodiment, the method for displaying the above-described swing target image 23 having a substantially spherical shape or a shape similar thereto, for example, will be described in more detail as follows 1-3.
1. How to display the swing target image 23 in a space such as evening, night, or dimly lit room (1) When visible light (predetermined color) laser light is irradiated on a space such as evening, night, dimly lit room, etc. The laser beam is reflected by dust and water vapor, and the laser beam is visible to the human eye. When it is irradiated with a laser beam with relatively high power in a dim space (more preferably, the focus of the laser beam is at or near the position where the swing target image 23 is to be displayed. When aligned, you can see some lines of laser light. Thus, an apparatus for irradiating a laser beam to a relatively dark place such as a night to show a human to the laser beam has been put to practical use as an apparatus for a “laser show” or the like.
(2) And if you irradiate such human-visible laser light from two different places and cross each other at one point in space, the power of the laser light is nearly double at that point Thus, only the intersection is more clearly visible to the human eye than the rest.
(3) When one point where the two laser beams intersect is defined as one dot, the intersection of the two laser beams (with the laser beam within a predetermined angle range) is used in the same manner in the vicinity of the dot. If a plurality of dots are formed at a high speed (by shaking at a high speed), a plurality of dots will be accumulated in the space. A substantially spherical swing target image that can be visually recognized as an object appears in the space. In this case, as described above, not only the laser beams are irradiated from the two laser irradiation units 26a and 26b and crossed at a plurality of points in the air, but also the laser beams from three or more laser irradiation units. May be made to cross at a plurality of points in the air.
2. Regarding the method of displaying the swing target image 23 in the outdoor space in the daytime (1) When visible light is irradiated in the outdoor space in the daytime, the laser light is reflected by minute dust or water vapor in the air. , Almost invisible to human eyes.
(2) However, near infrared laser light is irradiated to the outdoor space in the daytime, and the user views the near infrared laser light using a goggle type night vision camera (infrared camera) mounted on the head. If this happens, you can see this near-infrared laser beam.
(3) And if the near-infrared laser light visible to the human eye is irradiated from two different places through such a night vision camera and cross each other at one point in space, the crossing point Then, since the power of near-infrared laser light is nearly doubled, only the intersection is more clearly visible to the human eye than the rest.
(4) One point where the two near-infrared laser beams intersect is defined as one dot, and the intersection of the two near-infrared laser beams is similarly set in the vicinity of the dot (the laser beam is within a predetermined angle range). If a plurality of dots are formed at a high speed (by shaking at a high speed in the inside), a plurality of dots will be accumulated in the space. A substantially spherical swing target image that can be visually recognized as a swing target appears in the space. In this case, as described above, the near-infrared laser light is irradiated from each of the two laser irradiation units to cross them at a plurality of points in the air, and each of the three or more laser irradiation units receives a near-red light. You may make it irradiate an external laser beam and make them cross | intersect several points in the air.
3. About a method using a water screen (1) Conventionally, a method of displaying an image using a “water screen” (a mist-like screen formed in a space by ejecting water vapor or smoke) Already used in many theme park attractions.
(2) Even in the first embodiment, a small water screen is formed by ejecting water vapor or smoke upward from below in a part of the space near the feet in front of the user (the space above the center of the base 22). By irradiating a plurality of laser beams toward the water screen from a plurality of positions on the right side, left side, and / or rear of the user, the water screen is approximated with an image of a real ball or the like. A similar substantially spherical swing target image can be displayed.

  As described above, the sensor-incorporated mat 22 in FIG. 2 has the same photoelectric sensors 1a, 1b, 2a, 2b, 3a, 3b, 4a, 4b, 5a, 5b, 6a and 6b as described in FIGS. Is built-in. 2 incorporates a processing device (substantially the same as the processing device 11 shown in FIG. 6) connected to each of the photoelectric sensors. In the space above the sensor-incorporated mat 22, the position corresponding to the position where the actual golf ball 8 shown in FIG. 6 is disposed (the same relationship as that shown in FIG. 6 for each photoelectric sensor). 2), the swing target image 23 in FIG. 2B is displayed. Therefore, in the first embodiment, when the user 20 swings the actual golf club 9 with respect to the swing target image 23, the swing of the user 20 is based on the output from each photoelectric sensor (see FIG. 6). (Such as the club head speed and the face direction of the club head) can be detected by a method similar to that of the conventional golf shot practice machine described above with reference to FIGS.

  Next, FIG. 3 is a conceptual block diagram for explaining the internal configuration of the swing practice device 21. In FIG. 3, 30 is a control unit configured by a CPU (central processing unit) and a predetermined program, and 31 is an output from each photoelectric sensor built in the sensor built-in mat 22 (the photoelectric sensor 3b described in FIG. 6). , 4b, 5b, 6b), the head 9a of the golf club 9 swung by the user 20 based on the sensor external output signals 3d, 4d, 5d, 6d) apparently contacts at least a part of the swing target image 23. A contact detection unit for detecting whether or not the head 9a has passed at least a part of the swing target image 23 = whether the head 9a has swung or not, and 32 is built in the sensor-incorporated mat 22 Output from each photoelectric sensor (sensor external output signals 3d and 4d from the photoelectric sensors 3b and 4b described in FIG. 6). Accordingly, a head speed detection unit 33 for detecting the speed of the head 9a of the golf club 9 swung by the user 20 at the time of shot (immediately before impact), outputs from each photoelectric sensor built in the sensor built-in mat 22 The golf club 9 swung by the user 20 based on the sensor external output signals 1d, 2d, 3d, 4d, 5d, 6d from the photoelectric sensors 1b, 2b, 3b, 4b, 5b, 6b described in FIG. A face direction detection unit for detecting the face direction (face surface angle) at the time of shot of the head 9a (immediately before impact), 34 is a timer for measuring the passage of time, and 35 is a user's swing state (swing result) ) And the character information indicating the flight state of the golf ball corresponding to each of the patterns Fine wherein a sound and character database, for recording in association with each other and an acoustic information indicating the impact sound of the golf ball corresponding to each pattern.

  The acoustic / character database 35 includes, for example, acoustic data indicating a golf ball hitting sound corresponding to the content of each shot (result of swing) such as an accurate shot, a left hook OB, or a right slice OB, Characters indicating the content of the result of the swing and character data indicating the flight distance of the golf ball are recorded in association with the content of each shot (result of the swing).

  The contact detection unit 31 outputs from each photoelectric sensor built in the sensor built-in mat 22 (sensor external output signals 3d, 4d, 5d, 6d from the photoelectric sensors 3b, 4b, 5b, 6b described in FIG. 6). ), When the sensor external output signals 5d and 6d are in the light shielding state almost simultaneously (within a predetermined time) while the head 9a passes between the optical axes 3c and 4c, the user 20 It is determined that the head 9 a of the golf club 9 that has swung has apparently contacted at least a part of the swing target image 23. The contact detection unit 31 outputs signals from the photoelectric sensors built in the sensor built-in mat 22 (sensor external output signals 3d, 4d, 5d from the photoelectric sensors 3b, 4b, 5b, 6b described in FIG. 6). 6d), when the sensor external output signals 5d and 6d are not in a light-shielding state almost simultaneously (within a predetermined time) while the head 9a passes between the optical axes 3c and 4c, That is, when the sensor external output signals 5d and 6d are in the light-shielded state, the head 9a of the swinged club head 9 greatly deviates from the correct trajectory, and the swing target image It is determined that the player has swung with no apparent contact.

  Further, the head speed detection unit 32 is based on outputs from the respective photoelectric sensors built in the sensor built-in mat 22 (sensor external output signals 3d and 4d from the photoelectric sensors 3b and 4b described in FIG. 6). By measuring the time from the time when the sensor external output signal 3d is in the cut-off state to the time when the sensor external output signal 4d is in the cut-off state, the speed of the club head 9a during the shot (immediately before the impact) is obtained. To detect. Note that the detection method performed by the head speed detection unit 32 is substantially the same as that described above with reference to FIGS.

  Further, the face direction detection unit 33 outputs signals from the photoelectric sensors built in the sensor built-in mat 22 (sensor external output signals from the photoelectric sensors 1b, 2b, 3b, 4b, 5b, 6b described in FIG. 6). 1d, 2d, 3d, 4d, 5d, 6d), the face direction is determined based on the pattern of each sensor external output signal. That is, the face direction detection unit 33 acquires the sensor external output signals 1d, 2d, 5d, and 6d while the club head 9a passes between the optical axes 3c and 4c. When the sensor external output signals 5d and 6d are simultaneously shielded when the sensor external output signals 1d and 2d are both shielded, the face of the club head 9a faces the correct center line 13. It is determined that When the sensor external output signals 1d and 2d are both shielded, and the sensor external output signal 5d is shielded before the sensor external output signal destination 6d, the face surface of the club head 9a is It is determined that the center line 13 is directed leftward. Further, when the sensor external output signals 1d and 2d are both shielded, and the sensor external output signal 6d is shielded before the sensor external output signal destination 5d, the face surface of the club head 9a is It is determined that the center line 13 is directed rightward. The detection method performed by the face direction detection unit 33 is substantially the same as that described above with reference to FIGS.

  Further, the timer 34 is based on an output from the contact detection unit 31 for a predetermined time (from a point in time when the head 9a of the golf club 9 swung by the user 20 apparently contacts at least a part of the swing target image 23). When the time that can be arbitrarily set by the user, for example, for 3 to 5 seconds has elapsed, a signal indicating that is output to the control unit 30.

  Next, the operation of the control unit 30 will be described with reference to the flowchart of FIG. Based on the output from the contact detection unit 31, the control unit 30 determines that the head 9 a of the golf club 9 on which the user 20 swings is the swing target image 23 (“swing target image” in FIG. 4). ”) (When the determination in step S1 in FIG. 4 is YES), the laser beam irradiation operation is stopped from the laser beam irradiation units 26a and 26b, and the swing target image is displayed. 23 is deleted from the space (step S2). At this time, the control unit 30 estimates the contents (results) of the swing shot by the user based on the outputs from the head speed detection unit 32 and the face direction detection unit 33 (step S3) (in addition, The control unit 30 controls the timer 34 based on a signal from the contact detection unit 31 to start measurement). Then, the control unit 30 extracts the striking sound and display content corresponding to the estimated content from the sound / character database 35 (step S4), and the extracted striking sound and display content are displayed on the speakers 25a and 25b and the display. Output from the unit 24 (steps S5 and S6).

  For example, (1) when the control unit 30 indicates that the face direction from the face direction detection unit 33 is a direction substantially parallel to the correct center line 13 (see FIG. 6), the shot content Is correctly in line with the basics (the ball flew on the fairway), and the ball flight distance corresponding to the head speed is estimated based on the head speed from the head speed detector 32 (step S3). Then, the control unit 30 extracts the ball hitting sound and the display content corresponding to the estimated shot content (the ball flew on the fairway and the flight distance of the ball) from the sound / character database 35 (step S30). S4). Then, the control unit 30 outputs the extracted impact sound (the impact sound at the time of the correct shot) from the speakers 25a and 25b (step S5), and also displays the extracted display content (for example, “Fairway OOyard”). Is displayed on the display unit 24 (step S6).

  (2) When the face direction from the face direction detection unit 33 is deviated leftward from the center line 13 by a predetermined angle or more, the control unit 30 displays the content (result) of the shot. A left hook OB is estimated (step S3). Then, the control unit 30 extracts the ball hitting sound and the display content corresponding to the estimated shot content from the acoustic / character database 35 (step S4). Then, the control unit 30 outputs the extracted impact sound (the impact sound in the case of the left hook OB) from the speakers 25a and 25b (step S5), and the extracted display content (for example, “left hook”). The character string “OB”) is displayed on the display unit 24 (step S6).

  Further, (3) when the face direction from the face direction detection unit 33 is biased to the right by a predetermined angle or more from the center line 13, the content (result) of the shot is A right slice OB is estimated (step S3). Then, the control unit 30 extracts the ball hitting sound and the display content corresponding to the estimated shot content from the acoustic / character database 35 (step S4). Then, the control unit 30 outputs the extracted impact sound (the impact sound in the case of the right slice OB) from the speakers 25a and 25b (step S5), and the extracted display content (for example, “right slice”). The character string “OB”) is displayed on the display unit 24 (step S6).

  When the control unit 30 receives a “signal indicating that the club head 9 a has touched the swing target image 23” from the contact detection unit 31, the control unit 30 controls the timer 34 to measure the time from that point. Start measuring. When the timer 34 measures the passage of a predetermined time thereafter (for example, 3-5 seconds), the timer 34 outputs a signal indicating that the passage has passed to the control unit 30. When the control unit 30 receives the signal from the timer 34 (when the determination in step S7 is YES), the control unit 30 controls the laser beam irradiation units 26a and 26b to irradiate the laser beam again, so that the space is swung. The target video 23 is displayed (step S8).

  On the other hand, when the head 9a of the golf club 9 swung by the user 20 apparently does not contact the swing target image 23 based on the output from the contact detection unit 31 (step of FIG. 4). When the determination of S1 is NO), the display of the swing target image is left as it is, and a predetermined buzzer sound is output from the speakers 25a and 25b (step S9), and the character “idle” is displayed on the display unit 24. Is displayed (step S10).

  In the first embodiment, the content (result) of the user's shot is one of the above (1) correct shot, (2) left hook OB, and (3) right slice OB. The estimation / determination by the control unit 30 depends on how far the face direction of the head 9a deviates from the direction of the correct center line 13 (see FIG. 6). it can. For example, the user can arbitrarily set the width of the fairway, for example, between 20 m and 100 m, and input it to the swing practice device 21. Based on the fairway width arbitrarily set and input by the user, the control unit 30 determines that the ball flight direction estimated from the face direction of the head 9a at that time is inside the fairway. 1) It is determined that the shot is correct, and when the ball's shot direction estimated from the face direction of the head 9a at that time is outside the fairway, it is determined as (2) left hook OB or (3) right slice OB. .

  As described above, in the first embodiment, the user 20 swings the actual golf club 9 with respect to the swing target image 23, and the club head 9 a apparently contacts at least a part of the swing target image 23. At that moment, as if the actual golf ball was actually shot, the swing target image 23 disappears and a ball hitting sound corresponding to the shot content is heard. Further, the shot contents at that time (for example, “fairway OO yards”, “right hook OB”, “left sloshi OB”, etc.) are displayed on the display unit 24. On the other hand, when the user 20 swings the actual golf club 9 with respect to the swing target image 23 and the club head 9a apparently does not contact at least a part of the swing target image 23, it is as if the actual target In the same manner as when the golf ball is swung with respect to the golf ball, the swing target image 23 remains as it is, and the ball hitting sound is not heard (only the warning buzzer sound is output). Further, the shot content at that time (for example, “idle swing”) is displayed on the display unit 24.

  Therefore, according to the first embodiment, since a real golf ball is not used for swing practice, it is not necessary to install a net for capturing a real golf ball, and the real golf club can be easily and at any time. Can be used to practice swinging, and a sense of reality can be obtained as if the actual golf ball is actually swinging.

  Next, a second embodiment of the present invention will be described. The basic configuration of the second embodiment is the same as that of the first embodiment. The difference is that, in the second embodiment, as shown in FIG. 5, a tee 41 made of an elastic member such as silicon rubber is disposed below the position where the swing target image 23 is displayed. is there. The lower end of the tee 41 is fixed to the mat 22.

  In the second embodiment, when the user swings the golf club 9 with respect to the swing target image 23, the lower end portion of the head 9a of the golf club 9 hits the tee 41 in most cases. Become. Therefore, according to the second embodiment, when the user swings with respect to the swing target image 23, the user can actually obtain the feel of hitting the tee 41, so that it is as if the golf was actually golf A strong sense of presence can be obtained as if swinging against the ball.

  The embodiments of the present invention have been described above. However, the present invention and the constituent elements constituting the present invention are limited to those described as the respective embodiments and the respective elements constituting the respective embodiments, respectively. Various modifications are possible. For example, in the example shown in FIG. 1, the swing practice device 21 is arranged in front of the user 20, but in the present invention, a swing provided with a laser beam irradiation unit for displaying the swing target image 23. The practice device 21 may be arranged on the right side, the left side, and / or the rear side of the user 20 in FIG.

  In the first and second embodiments, two laser beams 27a and 27b are used to display the swing target image 23 in space. In the present invention, the swing target image 23 is displayed. The method is not limited to the method using the laser beam described above. For example, an image of a golf ball may be displayed in the air by a hologram technique (a technique for displaying an image in a space by a hologram is disclosed). (For example, refer to Japanese Patent No. 3431192, Japanese Patent Application Laid-Open No. 08-44279, Japanese Patent Application Laid-Open No. 2002-49295, etc.).

  In the first and second embodiments, the photoelectric sensors (see FIG. 6) built in the mat 22 are used to detect the swing state of the golf club 9 by the user 20 (see FIG. 6). There are a number of documents such as Japanese Patent Publication No. 61-47108 and Japanese Patent Application Laid-Open No. 08-224332 as a document disclosing a method of using a photoelectric sensor for detection. It is not restricted to the method of using. In the present invention, for example, (a) a method of detecting a swing state using a magnet attached to the club head and a magnetic sensor built in the mat (the club head speed, the face surface angle, etc. are detected by the magnetic sensor). (E.g., see Japanese Patent Laid-Open Nos. 63-249588 and 2001-314540), and (b) by capturing a user's swing with a video camera and analyzing the captured image A method for detecting a swing state (see, for example, Japanese Patent No. 2585657 and Japanese Patent Laid-Open No. 05-55157 as a method for disclosing a swing state from a captured image), (c) Acceleration built in a golf club A method of detecting a swing state by a sensor (acceleration sensor built in a golf club) As discloses a method for detecting a swing state, see, for example, such KOKOKU 05-55156 Patent Publication), such as may be employed various methods.

  Furthermore, in the said Example 1, 2, although the golf club swing practice apparatus was illustrated, this invention is not applied only to golf club swing practice, for example, tennis racket swing practice, Of course, it can be applied to practice of swinging a baseball bat. In the present invention, the swing target video displayed by the swing target video display means is not only a video stationary in the space but also a video moving in the space (for example, a baseball ball or tennis) An image in which the ball moves from the front toward the user). For example, while the laser beams from the two laser irradiation units 26a and 26b (see FIG. 2) are swung at a predetermined angle at a high speed, the irradiation direction of the laser beam is changed at a predetermined speed according to the trajectory of the image moving in the space at the same time. By displacing, the “swing target image moving in the space” can be displayed in the space.
