Attach a, 5b, 6a, 6b. The type of sensor is a transmissive photoelectric sensor, 1a, 2a, 3a, 4a, 5a,
6a is a light emitting side, and 1b, 2b, 3b, 4b, 5b and 6b are light receiving sides. The light source on the light emitting side and the external output for outputting the light receiving / light blocking state on the light receiving side are built into the sensor amplifier.
The light source generates light pulse-modulated so as not to be affected by ambient 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 9a during the swing of the golf club 9 can be detected.

Next, the use and mounting position of the sensor will be described.

1a-1b and 2a-2b are golf balls 8
The left / right deviation of the club head 9a immediately before a shot is detected with respect to the shot direction. The mounting position is the center line 1 which is parallel to the swing direction and passes through the center of the golf ball 8.
Separate from both sides by the same distance. The distance between 1a and 2b or 1b and 2a is wider than the diameter of the golf ball 8 and narrower than the width of the club head 9a.

Club heads 3a-3b and 4a-4b are provided.
The shot speed of a is detected. The mounting position is perpendicular to the swing direction, 4a-4b is installed so that the optical axis 4c can be formed in front of the golf ball 8, and 3a-3b is 4a-4b.
Install as close as possible to.

5a-5b and 6a-6b are club heads 9
The face direction of a is detected. Mounting position is center line 1
Optical axes 5c and 6c opened from 3 to both sides at the same angle
And the intersection of the optical axes 5c and 6c is the center line 13
A sensor is installed so that it can be placed in front of the golf ball 8 above.

It should be noted that all the sensors are set to a height at which the club head 9a passes just before the golf ball 10 is shot by the swing motion of the golfer 10 and are mounted at positions where they do not hinder the swing motion.

Next, the processing device 11 for displaying the head speed, the shot direction and the like will be described.

The head speed is displayed by the head speed display means 11a. As an example of realizing the means, a reference clock generator, a counter, a circuit for setting the distance between the sensors 3a-4b, a division circuit, and a numeral display are provided, and the sensor external output is output from the time when the sensor external output signal 3d is cut off. The clock pulse generated from the reference clock generator is counted by the counter until the signal 4d is cut off, the distance of the sensors 3a-4b is divided by the count value by the division circuit, and the result is displayed on the numeral display. By displaying, speed display can be realized.

The shot direction is displayed by the shot direction display means 11b. As an example of realizing the means, the sensor external output signals 1d, 2d, 5d and 6d are used to display the shot direction from four signal patterns. The shot direction is displayed by turning on the light emitting diode in the directions such as middle, left, and right. External sensor output signal 1d, 2
The timing of inputting d, 5d, and 6d is limited while the club head 9a is passing between the optical axes 3c and 4c in order to detect the state immediately before the shot of the golf ball 8.
As an example of the display of the shot direction after detection of the sensor external output signal, when both 1d and 2d are in the light-shielded state and 5d and 6d are simultaneously shielded, the center of the golf ball 8 is shot immediately before the club head 9a hits the golf ball 8. And the face surface faces the direction of the center line 13. As a result, in the display of the shot direction, the middle direction is displayed by lighting the light emitting diode. Also, both 1d and 2d are 5
When d is shielded first, the club head 9a passes through the center of the golf ball 8 immediately before the golf ball 8 is shot, and the face surface faces the left side with respect to the center line 13 in the shot direction. As a result, in the display of the shot direction, the left direction is displayed by lighting the light emitting diode. The display of the shot direction may be a patterned display such as middle, left, and right, or the sensor external output signals 1d, 2d, 5
The detection states of d and 6d may be displayed as they are.

The shot validity / invalidity determination means 11c determines whether or not the current shot is valid for displaying the head speed and the shot direction. In order to determine whether the shot is valid or invalid, one of the sensor external output signals 1d or 2d, 3d, 4d, 5d, 6d that does not detect passage of the club head 9a within a predetermined time from a reset operation described later. If so, it is determined that the shot is invalid, and this is notified by the notification means 11d such as a buzzer so that the golfer 10 can recognize this. External sensor output signal 1d or 2
When all of d, 3d, 4d, 5d, and 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, and the display of the head speed and the display of the shot direction are performed.

The resetting means resets the above-described head speed display, shot direction display, and shot valid / invalid judging means in preparation for the next shot.
Perform at 11e. The resetting means resets the golfer 10 by placing the club head 9a in front of the golf ball 8 before the shot or by swinging the club head 9a. As an example of the means, the optical axes 5c and 6c which are shielded when the golfer 10 places the club head 9a in front of the golf ball 8 before the shot or when the club head 9a is rocked is used. Optical axis 5
If a predetermined time has elapsed after both the sensor external output signals 5d and 6d of c and 6c are in the light-shielded state, the reset signal
11g is output, and this is given to the head speed display means 11a, the shot direction display means 11b, and the shot valid / invalid determination means 11c to be reset. Also, reset signal 1
When 1 g is output, a notification means 11f such as a buzzer notifies the golfer 10 that the golfer 10 is reset and the next shot can be made.

In this embodiment, the movement of the club head of less than 10 m / s is the movement of shaking the club head, and the movement of the club head is 10 m / s or more. The movement of the club head was judged as a shot. The calculation of the time during which the sensor external output signals 5d and 6d are shielded from light is performed as follows, for example, when the iron head has a thickness of 10 mm and is moved at 10 m / s. 1 / (10 / 0.01) = 1ms
That is, the reset signal may be output after 1 ms has elapsed since both the sensor external output signals 5d and 6d are in the light-shielded state. In the shot operation, since the light is shielded for less than 1 ms, the reset signal is not output. Further, in the operation of placing the club head in front of the golf ball, the reset signal is output because the sensor external output signal is shielded for 1 ms or longer.
