Description

  The present invention relates to a structure of a windmill for guiding a game ball that is provided on a game board of a pachinko machine and changes the fall path of the game ball.

  A windmill of a pachinko machine penetrates a nail through the center of an impeller formed by radially forming blades on the back surface of the disc portion, and hits the nail perpendicularly to the front surface of the game board. It is provided rotatably in the game ball drop area on the front surface so that a change is given to the fall path of the game ball that collides with the impeller.

By the way, as shown in the following Patent Documents 1, 2, etc., the conventional windmill is simply provided on the front surface of the game board so as to freely rotate, and has only a function of rotating naturally by an impact when a game ball collides, It was poor in change.
Japanese Patent No. 2983968 Japanese Patent No. 3710707

  Therefore, the present invention is configured to make the conventional windmill move more varied, and to increase the fun of pachinko games.

For this purpose, a game ball guiding windmill of a pachinko machine according to the present invention comprises an impeller rotatably provided on a support shaft and an electric actuator for moving the support shaft forward and backward, and the impeller is mounted on a game board. A through-hole that can be accommodated is formed, and the impeller moves forward and backward so that the impeller appears and disappears in the game ball dropping area on the front surface of the game board.
Further, the present invention is the above-described windmill for guiding a game ball, wherein the impeller is formed such that the rear surface of the disk-shaped front surface portion is conical, and a plurality of blades are radially disposed on the outer periphery of the cylindrical bearing portion through which the support shaft is inserted. It is characterized by being formed.

When the impeller protrudes into the game ball falling area on the front of the game board, the game ball collides with the impeller, while when the impeller fits in the through hole of the game board, the game ball collides with the impeller. Since it can pass through the game ball falling area without doing so, the flow of the game ball can be greatly changed according to the appearance and appearance of the impeller. For this reason, the situation change of the game board surface where a game ball falls is diversified, and the interest of a pachinko game can be increased.
Further, by forming the rear surface of the disk-shaped front portion of the impeller into a conical shape, it is possible to prevent the game ball from being bitten when the impeller moves forward and backward.

  Next, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view of a part of a game board provided with a windmill for guiding a game ball according to the present invention, and FIG. 2 is a longitudinal sectional view thereof. In the figure, 1 is an impeller and 2 is a game board in which a through hole 3 in which the impeller can be accommodated is formed. The impeller 1 is formed such that the rear surface 1b of the disk-shaped front surface portion 1a is formed in a conical shape, and three blades 1c are formed radially on the outer periphery of the cylindrical bearing portion 1e, and the rear end of the cylindrical bearing portion 1e. A disc-shaped rear surface portion 1d that substantially matches the inner diameter of the through hole 3 is formed in the portion. 4 is a support shaft that rotatably supports the impeller 1 by being inserted into the cylindrical bearing portion 1e, and 5 is an electric motor provided with a mounting member 6 on the back side of the game board 2, and fixed on the mounting member. The support shaft 4 is a solenoid that is an actuator, and extends at the tip of the operating shaft 7 of the solenoid 5. Reference numeral 8 denotes a coil spring provided on the operating shaft 7. For this reason, when the solenoid 5 is not excited, the operating shaft 7 and the support shaft 4 are advanced forward by the elasticity of the coil spring 8, and the impeller 1 provided at the tip of the support shaft 4 is a game board. 2 It protrudes into the game ball falling area on the front. When the solenoid 5 is energized by energization, the operating shaft 7 and the support shaft 4 move backward against the elasticity of the coil spring 8, so that the impeller 1 is a game as shown in FIGS. It is confined in the through hole 3 of the board 2.

  Thus, since the impeller 1 appears and disappears by operating the solenoid 5, when the impeller 1 protrudes, the game ball falling on the front surface of the game board 2 collides with the impeller 1 and the impeller While 1 freely rotates and the falling direction of the game ball changes, when the impeller 1 is confined in the through hole 3, the game ball passes through this area without colliding with the game ball. The situation on the front of the game board can be changed greatly. For this reason, for example, a winning hole, a special winning hole (not shown), etc. can be arranged on the front surface of the game board 2 so that the winning probability of the game ball changes. Thus, by providing this game ball guiding wind turbine, the board surface configuration of the game board can be diversified, and the pachinko game can be made more interesting.

  In addition, since the impeller 1 shown in this embodiment formed the back surface 1b of the disk-shaped front part 1a in the conical shape, when the impeller 1 moves back and forth, the back surface 1b and the opening of the through hole 3 are opened. The possibility of causing a so-called ball bite can be reduced by being sandwiched between the edges.

  In addition, by forming a disc-shaped rear surface portion 1d that substantially matches the inner diameter of the through hole 3 at the rear end portion of the blade 1c of the impeller 1, the through hole 3 is formed when the impeller 1 protrudes. A game ball that is blocked by the disc-shaped rear surface portion 1d and falls off the front surface of the game board is prevented from flowing into the through hole 3. Even if the disc-shaped rear surface portion 1d is not necessarily formed, by setting the gap between the outer peripheral surface of the cylindrical bearing portion 1e and the inner surface of the through hole 3 to be equal to or less than the diameter of the game ball, It is possible to prevent the game ball from flowing into 3.

  As described above, when the impeller 1 is caused to appear and disappear, it can be set as appropriate, such as when the jackpot is generated, when the jackpot is announced, when the jackpot is activated, in addition to the normal gaming state. In this embodiment, the impeller 1 is moved forward and backward by the solenoid 5, but it goes without saying that the impeller 1 may be moved forward and backward by an electric motor.

The perspective view of the game board which showed the operation state of FIG. The longitudinal cross-sectional view of FIG.
