[Detailed explanation of the invention] (a) Field of the invention This invention relates to the structure of a golf practice machine, and more specifically, the invention relates to the structure of a golf practice machine. This invention relates to the structure of a golf practice machine that allows angles to be confirmed simultaneously using figures and numbers.

(b) Background of the invention The present applicant has already developed a putting correction device and has already filed an application for it (Japanese Utility Model Publication No. 157382/1982).

This device monitors the putting conditions, i.e. the tilt of the head and the moving position of the sweet spot.
The display was made up of three parallel horizontal segments and three tilted segments, but these displays were not sufficient to immediately understand the status of the head.

Arrange them in parallel as detectors. These detector outputs are connected to a display via an amplifier and a microcomputer, and the display is connected to a first fan-shaped segment B with an opening angle slightly smaller than the semicircular shape in order to display the direction of the face angle.

(e) Effect of invention This idea will be explained in detail based on the drawings.

As shown in Figure 1, a virtual straight line
A sweet spot detector A consisting of a pair of sensors a and a', a face angle detector B consisting of a pair of sensors b and b', and a pair of sensors c and c' centered on -Y. The head displacement detectors C are sequentially exposed and arranged in the plane of the horizontal table 1.

These detectors A, B, and C are connected to a segment 4 via an amplifier 2 and a microcomputer 3 built into a horizontal table 1, as shown in FIG.

The computer 3 is programmed to cause the concrete segments 5 corresponding to the input signals of the detectors A, B, and C to emit light.

The segment 5 is a circular segment A that displays the detection result from the sweet spot detector A.
1, A2, A2', A3, A3', A4, A4', and a plurality of segments B1, B2, B2', B3, B3' that display the detection results from the face angle detector B. It consists of fan-shaped segments that are combined to form a fan-shaped overall shape.

The fan-shaped segment portion indicates the direction of the face angle of the golf club,
The first fan-shaped segment B1 has a slightly smaller opening angle than the semicircular shape, and the first fan-shaped segment B1 has the same center and the same radius as the first fan-shaped segment B1, and is arranged continuously in the circumferential direction with the center point symmetrical. 1
A pair of second fan-shaped segments B2, B2' forming a complete semicircular shape with the fan-shaped segment B1; a pair of third fan-shaped segments B arranged consecutively in
3 and B3'.

Further, the circular segment is provided outside the center point of each fan-shaped segment and displays the position of the sweet spot corresponding to the face position of the golf club, and the position of the discrepancy between the club head and the first circular segment A1. In order to
3, a pair of second circular segments A2, A2' provided in the front part of B3', and adjacent to the second circular segments A2, A2', provided in the third fan-shaped segments B3, B3'. a pair of third circular segments A3, A3', and a pair of fourth circular segments A4, A4' provided within the second fan-shaped segments B2, B2' adjacent to the third circular segments A3, A3'; It is composed of.

Next, each state of the head and sole will be explained with reference to FIGS. 1 and 3 as follows.

In the state of 1, that is, when the head and sole HS passes over both sensors a and a' of the sweet spot detector A, perpendicularly above the virtual line X-Y,
The reflected light from the sole is input to both a and a', and the first circular segment A1 of the display 4 emits light via the computer 3. See Figure 3 A.

2. In the above state, that is, when the movement is vertically shifted orthogonal to the virtual straight line do.
See Figure 3 B and C.

3 In the next state, that is, when the head sole HS simultaneously passes over each sensor b and b' of the face/angle detector B, orthogonal to the virtual straight line X-Y, both sensors react simultaneously and the computer 3 through the first fan-shaped segment B1 and the second
The fan-shaped segments B2, B2' emit light. Third
See Figure A.

Therefore, if the conditions of the first and third terms are met, the player's face angle is straight and the sweet spot is on the virtual straight line X-Y.
It is possible to concretely perceive that the object has passed directly above the object.

4 Furthermore, if the head/sole HS passes over the above two detectors A and B and then passes over the head deviation detector C in the same manner as in the previous section 1, both sensors c and c' will react and the The light emitting state shown in Figure 3 A is maintained.

5 However, in general, the sole part of a golf ball has a short straight part that emits reflected light, and the face part of a putter has a variety of shapes, depending on the type of each manufacturer and the personal preferences of the players. When a wood or putter is used, the sensitivities of sensors c and c' and, by extension, the input to the computer 3 are uncertain. Therefore, if the object passes over detector C with a vertical deviation from the virtual straight line and computer 3 from face angle detector B
The input to the head is invalidated, the concrete display of the concrete segment part 5 that has been emitting light is erased, and instead only the sensor signal sensed by the head displacement detector C is sent to the third circular segment A3 via the computer 3. Alternatively, it may be applied to A3' to cause only one of A3 and A3' to emit light. Figure 3 b,
See c.

6 Next, the state of the head and sole HS in Figure 1,
In other words, if the object deviates downward from the virtual straight line X-Y and tilts to the right, the sensors a and a' of the sweet spot detector A will only sense a', and the angle sensors b and b' will sense b. ' reacts before b. Based on both outputs, in the concrete segment unit 5, the fourth circular segment A4 emits light, and the fan-shaped segment groups B1, B2', and B3' emit light. See Figure 3.

7 In other cases, “Figure 3 d, ho, he, to, li”
can also be easily inferred from the explanations of 1) to 6) in the previous section.

8 Furthermore, if the conditions of paragraphs 1), 3), and 4) are satisfied, the output of each sensor in paragraphs 1) to 6) above is sent to the point segment 6 via the computer 3, respectively. The score is 100, and in other cases, if you set a predetermined number of demerit points in advance, you can earn points for each play.
Segment 6 allows players to not only recognize their own score numerically, but also visually check their playing posture through the concrete display of concrete segment 5.

In Fig. 1, numeral 7 is an angle segment that numerically displays the set face angle, and 8 is a head speed segment that numerically displays the head speed. .

(f) Effects of the invention As a result of the above, in this invention, the direction of the face angle is displayed in the form of a head using fan-shaped segments, and the position of the ball is displayed using circular segments. However, the display will appear as if the ball is in contact with the club head, allowing you to instantly and reliably grasp the direction of the face angle, the position of the sweet spot, and the deviation of the head. By checking the number of points in the state, you can obtain the effect of being able to grasp the progress process at the same time.
