Description

  The present invention relates to a ball launcher for a gaming machine for launching a game ball within a game board surface.

  In order to launch a game ball in the surface of the game board, a ball launcher provided with a launch rail supported by a rail mounting block formed on a base plate and a ball cage for projecting the game ball on the launch rail is provided. It is done. A game ball launched by such a ball launcher is guided into a game board surface while being guided by a guide rail provided at the tip of the launch rail.

  However, due to molding errors and assembly errors of the components of the ball launcher, the launch rail is not parallel to the game board surface, and the game ball is fired to the glass surface side. There was a problem that an unpleasant collision sound was generated when contacting the surface.

  In order to solve such a problem, there is one that adjusts the inclination of the launch rail by providing an adjustment screw on the tip side of the launch rail attachment member to which the launch rail is attached (Patent Document 1). When this adjusting screw is rotated in the tightening direction, its tip protrudes from the firing rail mounting member and comes into contact with the board on the game board surface side. In other words, by adjusting the amount of protrusion at the tip of the adjustment screw, the inclination of the launch rail relative to the game board surface can be changed, thereby allowing the launch direction of the game ball to be adjusted between the game board surface direction and the glass surface direction. It becomes. However, a skillful technique is required to finely adjust the amount of rotation of the adjusting screw, which is extremely difficult for non-experts. In addition, the adjustment screw is liable to be loosened by vibration.

  Therefore, a technique has been disclosed in which an angle adjustment block is provided instead of the adjustment screw so that even an unskilled person can easily perform the adjustment work (Patent Document 2). However, in Patent Document 2, when changing the mounting position of the angle adjustment block, the launch rail has to be removed each time, and there is a problem that workability is poor.

  Further, Patent Documents 1 and 2 adjust the inclination of the launch rail only at the tip end side of the launch rail to optimize the launch direction of the game ball, and the ball position of the game ball at the base end side of the launch rail. Cannot be adjusted. Therefore, since the ball cage may not be able to catch the true core of the game ball at the time of the ball, even if the inclination is adjusted on the tip side of the launch rail, the game ball is still fired to the glass surface side. was there.
