(Embodiment 1)
1 is a block diagram showing a golf practice apparatus according to Embodiment 1 of the present invention. This golf practice apparatus 100 includes a main body 2 that is supported by a tripod 1 and rotates in a horizontal direction, an LD (semiconductor laser) block 3 that emits laser spot light into the main body 2, and a laser that is emitted from the LD block 3. A rod lens 4 for branching light to generate a reference line and a power source 5 made of a secondary battery are provided. The LD block 3 and the rod lens 4 constitute an optical system unit 6.

  The LD block 3 includes a semiconductor laser 7 and a condenser lens 8. The LD block 3 is disposed obliquely downward in order to generate a reference line made of laser light on the ground. The main body 2 is made of plastic, and each leg of the tripod 1 is foldable. Further, the height of the tripod 1 can be adjusted. The size of the exit port 9 of the main body 2 is determined so that the laser beam branched from the rod lens 4 does not become higher than the height H of the main body 2. That is, the laser beam emitted from the rod lens 4 is restricted from being emitted above the main body 2 by the vicinity of the upper end portion 9 a of the emission port 9 of the main body 2. Thereby, as long as the position of the eyes is higher than that of the main body 2, the user does not feel dazzling.

  On the other hand, the lower end portion 9b of the exit port 9 is wide open so that the laser beam branched by the rod lens 4 is projected onto the ground directly below the main body. The optical system unit 6 is suspended from the main body 2 by a gimbal shaft, and the inclination can be automatically corrected by the weight of the optical system unit 6 (not shown).

  In the golf practice apparatus 100, the spot light emitted from the LD unit 3 enters the rod lens 4 and is emitted from the rod lens 4, so that the spot light is branched into a linear laser beam. This laser light is emitted from the lower side to the front side of the main body 2 to generate a straight reference line S on the ground as shown in FIG. The user installs a target T such as a hole ahead of the reference line S. Then, when practicing the pad, the user places the golf ball B on the reference line S and performs the pad toward the target T while checking the reference line S. In this way, the user can easily practice the pad while viewing the track of the golf ball B by standing the golf practice device 100 on the tripod 1 and emitting the reference line S made of laser light.

  FIG. 3 is an explanatory diagram showing an example of how to use the golf practice apparatus. As described above, the two golf practice apparatuses 100 are arranged to face each other so that the reference lines S emitted from the respective golf practice apparatuses 100 overlap each other. The reference line S is adjusted by rotating the main body 2 on the tripod 1. When the golf ball B is placed on the reference line S in this state, the golf ball B is irradiated with the laser beam from both sides of the golf ball B. Therefore, as shown in FIG. S is irradiated. FIG. 4A is a front view showing a state in which laser light is irradiated perpendicularly from the ground onto the golf ball. FIG. 4B is a plan view showing a state in which laser light is irradiated from before and after the golf ball. FIG. 4C is a perspective view showing a state in which laser light is irradiated from the front and back of the golf ball.

  A target T such as a hole is disposed on the reference line S. A protective block K is placed in front of the golf practice apparatus 100 closer to the target T so that the golf practice apparatus 100 does not fall when it hits the golf ball B. The protective block K may have a structure integrated with the target T (not shown). In this way, the user generates the reference line S on the ground, places the golf ball B on the reference line S, and practices the pad while watching the reference line S. According to the method of using the golf practice device 100, even if the putter blocks the irradiation of the reference line S from the golf practice device 100 on one side to the golf ball B, the golf ball B from the golf practice device 100 on the other side. Since the reference line S is irradiated, the user can practice without losing sight of the reference line S on the golf ball B when padding.

  FIG. 5 is an explanatory view showing another example of how to use this golf practice apparatus. In this usage method, two golf practice apparatuses 100 are arranged, and the reference line S emitted from the golf practice apparatus 100 is intersected to generate a target point M as an intersection. In this case, the ground is a slope, and the target point M is located higher than the golf practice apparatus 100. Similarly to the above, a target T such as a hole and a protective block K are arranged in front of the golf practice apparatus 100 on one side. The user places the golf ball B on the reference line S, and makes a pad toward the target point M while referring to the reference line S. The golf ball B travels along the reference line S emitted from the golf practice apparatus 100 on one side, but rolls down along the reference line S emitted from the golf practice apparatus 100 on one side while gradually drawing a parabola. The target T is reached. In this manner, by generating the target point M by intersecting the reference lines S, the user can perform padding toward the target point M. Further, it is easy to check the trajectory of the golf ball B even on the side of rolling down with a parabola.

(Embodiment 2)
FIG. 6 is a front view showing a golf practice equipment according to Embodiment 2 of the present invention. FIG. 7 is a block diagram showing the golf practice apparatus 200 shown in FIG. The golf practice apparatus 200 is different from the golf practice apparatus 100 shown in the first embodiment in that a light receiving unit 201 that receives a laser beam reflected by a face such as a putter and an output signal of the light receiving unit 201 It is the structure provided with the determination part 202 which determines a position and attitude | position, and the display part 203 which alert | reports the determination result of the determination part 202 to a user with a lamp | ramp. The light receiving unit 201 has a rectangular shape that is long in the horizontal direction, and a shutter 204 is movably provided on the front surface of the light receiving unit 201. Note that a buzzer may be used instead of the display unit 203.

  FIG. 8 is an explanatory view showing a method of using the golf practice apparatus 200 shown in FIG. The user positions the head H of the putter P on the reference line S generated by the golf practice device 200. The laser light reflected by the head surface of the putter is received by the light receiving unit 201 when the head surface of the putter P becomes substantially perpendicular to the reference line S. The light receiving unit 201 converts the received laser light into an electrical signal and transmits it to the determination unit 202. When the signal from the light receiving unit 201 continues for a predetermined time, the determination unit 202 determines that the head H of the putter P is in the correct position and posture, and turns on the lamp of the display unit 203. It should be noted that the pattern P is not determined to be in the correct position or orientation as long as the laser light is incident on the light receiving unit 201 temporarily (for example, 1 second or less).

  In the golf practice apparatus 200 according to the second embodiment, the correct position and posture of the putter P can be easily confirmed. Note that the range in which light can be received by the shutter 204 can be widened or narrowed. If the shutter 204 is opened widely, it can be received even if the reflected light Sr is slightly blurred, so that the determination is sweet. On the other hand, if the shutter 204 is opened narrowly, since the reflected light Sr is difficult to enter the light receiving unit 201, a severe determination is made.

  Even if the light receiving unit 201, the determining unit 202, and the display unit 203 are not provided (the golf practice apparatus 100 according to the first embodiment), if the reflected light Sr is visually matched with the reference line S, It can be determined that the person holds the putter P in the correct posture.

(Embodiment 3)
FIG. 9 is a front view showing a golf practice apparatus according to Embodiment 3 of the present invention. 10 is a block diagram showing the golf practice apparatus shown in FIG. This golf practice apparatus 300 is configured to include a whole body mirror 301 and an optical system unit 302 that generates a reference line by a laser beam provided at the upper end of the whole body mirror 301. The optical system unit 302 includes an LD block 303 that emits laser spot light, rod lenses 304 and 305 that branch the laser light emitted from the LD block 303 to generate a reference line, total reflection mirrors 306 and 307, and half It consists of a mirror 308. In addition, a plastic main body 309 housing the optical system unit 302 is provided with a power source 310 composed of a secondary battery. The LD block 303 includes a semiconductor laser and a condenser lens (not shown).

  The LD block 303 is disposed in the vertical direction, and a half mirror 308 is disposed on the LD block 303. A total reflection mirror 306 is disposed on the half mirror 308, and a rod lens 304 that generates a vertical reference line Sv is disposed in front of the total reflection mirror 306. Further, a total reflection mirror 307 is disposed on the side of the half mirror 308, and a rod lens 305 that generates a horizontal reference line Sh is disposed in front of the half reflection mirror 307. In order to adjust the height of the horizontal reference line Sh, the rod lens 305 is provided with a rotation shaft 311 perpendicular to the axial direction. The rotary shaft 311 is provided with an adjustment knob 313 via a gear 312. The optical system unit 302 is suspended from the main body 309 by a gimbal shaft, and the inclination can be automatically corrected by the weight of the optical system unit 302 (not shown).

  In this golf practice apparatus 300, the laser beam emitted from the LD block 303 is partially reflected laterally by the half mirror 308 and partially transmitted. The transmitted laser beam is reflected by the total reflection mirror 306 and is branched by the rod lens 304 to generate a vertical reference line Sv by the laser beam. On the other hand, the laser beam reflected by the half mirror 308 is reflected by the side total reflection mirror 307 and branched by the rod lens 305 to generate a horizontal reference line Sh by the laser beam. The vertical reference line Sv and the horizontal reference line Sh cross each other and are emitted in front of the full-length mirror 301.

  FIGS. 11 and 12 are explanatory views showing how to use the golf practice apparatus 300. A user stands in front of the full-length mirror 301 and holds a golf putter P. In this state, the vertical reference line Sv and the horizontal reference line Sh are irradiated from the golf practice apparatus 300 to the user in a cross shape. The user can see his / her appearance irradiated with the vertical reference line Sv and the horizontal reference line Sh with the full-length mirror 301. Specifically, the vertical reference line Sv is projected in the axial direction of the body of the user standing in front of the full-length mirror 301, and the horizontal reference line Sh is projected in the shoulder width direction. Then, the user can confirm the appearance with the golf club P with reference to the vertical reference line Sv and the horizontal reference line Sh. If the main body 309 includes a small video camera and recording means (not shown), the video is recorded in a state where the vertical reference line Sv and the horizontal reference line Sh are projected on the user's body. You can check your form.

  Since the position of the shoulder is important in the confirmation of the form, the horizontal reference line Sh is preferably projected at a predetermined height h from the user's shoulder and in the shoulder width direction. When the adjustment knob 313 is turned, the rod lens 305 rotates through the gear 312 and the rotating shaft 311 and the horizontal reference line Sh moves in the vertical direction. Thereby, the horizontal reference line Sh can be irradiated to an appropriate position according to the height of the user. Note that the laser beam used in the golf practice apparatus 300 is strong enough to cause no problem even if it enters the eyes.

(Other embodiments)
FIG. 13 is an explanatory view showing another embodiment of the present invention. The golf practice apparatus 400 has substantially the same configuration as the golf practice apparatus 300 according to the third embodiment, but an optical system unit 401 that generates the vertical reference line Sv is provided on the upper part of the full-length mirror 301, and the horizontal reference line The difference is that the optical system unit 402 for generating Sh is built in the main body and is stood on a tripod. The horizontal reference line Sv can be adjusted by changing the inclination of the main body on the tripod. Even in this case, as shown in FIG. 13, the vertical reference line Sv and the horizontal reference line Sh are projected in a cross shape on the user's body, so that his / her form can be objectively confirmed while looking at the full-length mirror 301.
