Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for determining the position of a shot shot in clay target shooting relative to a flying clay.

The projectile position determination device of the present invention projects the projectile position and the flying clay on the screen of a television receiver, and directly determines the error, deviation direction, etc. of the projectile position by viewing the image, and improves subsequent shooting techniques. The present invention is constructed in such a way that improvements can be made therein, and the invention will be described in detail below with reference to the drawings.

In Fig. 1, (I) indicates the upper and lower two barrels +21, +
21, and a small TV camera +31 is fixed to the lower barrel (2) with a supplementary bracket (4), and the small TV camera (3) has a cylindrical shape as shown in the second figure. An imaging lens barrel (7) containing an imaging lens thread (6) is protruded from the front end of the case (51).
) is equipped with a solid-state image sensor (8) as a photoelectric conversion element and other necessary parts, and this small television camera (3) aligns the optical axis of its imaging lens barrel (7) with the axis of the gun barrel (2). It is fixed in a position parallel to the

A normal video tape recorder 19) is connected to the above-mentioned small television camera (3) by a long electrical cord OG, and a monitor television receiver aυ is connected to the recorder +91.
Connect it.

The video tape recorder (9) is preferably equipped with a slowing mechanism, and may also be equipped with a static mechanism and a frame-advancing mechanism, if necessary. In addition, a normal television receiver may be used in place of the monitor television receiver αυ. The cathode ray tube screen of the television receiver (11) may have a transparent 3rd on board
By drawing the vertical and horizontal axes and concentric lines as shown in the figure, the A-Lyu (P) line on the screen is shown in a straight line.

This center point (P) indicates the firing position of the gun.

Next, the operation of this device will be explained along with an example of its use. After turning on the small television camera (3), video tape recorder 19), and monitor television image receiving filter, and in particular activating the slow mechanism of the recorder 19), the shooting field r.
At 9r, when the shooter holds a gun +11 and aligns the muzzle with the clay fired by the clay firing signal, the gun barrel (2)
A small television camera (3) attached to the camera captures an image of the flying clay, and the image is electrically converted and sent to the video tape recorder +91 to be recorded and projected on the cathode ray tube screen of the monitor television receiver αυ. If the shooter pulls the trigger in this state, the screen will shake violently due to the impact of the shot.

Now, the bullet does not hit, and the clay image (V) displayed on the screen just before shaking is at the center point C, as shown in the third cause.
If the bullet is located diagonally above and to the right from P), the firing position (
It can be determined that the point 2) is shifted diagonally to the left of the clay by the distance between V and P. The above judgments are made by the shooting coach by looking at the screen of the monitor TV receiver αυ.

At the end of the shooting T (ft), the shooter immediately plays the above-mentioned recorded tape on the monitor TV receiver 6aυ, judges the above-mentioned shot position by himself, learns his own habits and shortcomings, and uses it as reference material for the next shooting. .

According to the bullet position determination device for clay shooting of the present invention, the center point of the screen of the television receiver is set as the bullet position, and the error, deviation, etc. between the clay image displayed on the screen during shooting and the bullet IIZ position, etc. By being able to see the IKm of clay target shooters, you will be able to identify the habits and weaknesses of clay target shooters very specifically and clearly, and you can expect a dramatic improvement in your shooting skills. Furthermore, according to the present invention, since a solid-state imaging device that is resistant to vibration and impact is used as a photoelectric conversion element in the television camera fixed to the gun, it also has the advantage of being able to withstand the impact of the gun during shooting.
