Claims

[Scope of Claim for Utility Model Registration] (1) Three ball launch wheels A, B, and C that can independently adjust their speeds are combined in the same rotational direction as the axis of the ball launch barrel 2, which is the ball launch direction,
A ball game practice machine characterized in that the cylindrical body is disposed on the circumference of the cylindrical body with a gap slightly narrower than the diameter of the ball so that the ball can be gripped. (2) The ball launch cylinder 2 is formed into a substantially L-shape, the upper opening 2a is used as a ball input port, and the ball is brought into contact with the circumferential surface of the ball launch wheel A disposed at the upper part near the L-shaped intersection. , the rotational force of the ball launching wheel A causes the forward ball launching wheels A, B,
A ball game training machine according to claim 1, which is a utility model and has a feeding mechanism for feeding a ball between C and C. (3) A partition plate 3 is provided on the outer periphery of the L-shaped intersection of the ball launcher cylinder 2, an elongated hole 3a is formed in the partition plate 3, and the wheel spacing is adjusted from the outside at the elongated hole position according to the ball size. A ball game practice machine according to claim 1, which is a utility model and has a wheel spacing adjustment mechanism that can be tightened. (4) In the lower central part of the ball launcher 2,
An angle adjustment mechanism using a flexible wire 23 for changing the ball launch angle is provided, and the other end of the flexible wire 23 is connected to a change lever 24 disposed at the bottom of the handle 6a, so that the ball launch angle can be freely adjusted. A ball game training machine according to claim 1 of the utility model registration claim, characterized in that:
