Description

  The present invention relates to a game board for a pachinko machine in which it is easy to replace a ball repulsion body that rebounds from a ball collided with a ball launched along a guide rail from the front side.

In pachinko machine game boards, a ball-repellent body, also called a bounce rubber or stopper, is attached to the board decoration, and the board decoration is placed on the outside of the guide rail so that it is placed at the cut between the outer rail and the inner rail. By being fixed to the game area with a nail or a wood screw, the ball repellent rebounds so that it does not go to the direction of the outlet along the inner rail by the collision of the ball launched along the outer rail. Forms the way the spheres fly and flow. However, since the ball repulsion body is fixedly attached to the game area, a strong ball immediately after being launched to the game area along the guide rail from the launch mechanism collides with the same ball rebound surface of the ball repulsion body. As a result of repeated ball collisions, the ball rebound surface is soiled and elastically deteriorated. When the ball rebound surface is contaminated or elastically deteriorated, there is a problem that the appearance of the ball rebounds is deteriorated and the way of flying and the flow of the peculiar sphere formed by the ball repulsion body is changed. Therefore, when replacing an old ball repellent with dirt or elastic deterioration with a new ball repellent, it is necessary to remove the board decoration from the game board. However, since the board decoration is fixed to the game board with nails and wood screws, it takes a lot of labor and time to remove the board decoration from the game board so as not to damage the board decoration, the guide rail and the game area. There are some disadvantages.

  With reference to FIG. 2, the game board 1 of the pachinko machine will be described. The game board 1 has a form in which a decorative sheet 3 is bonded to one surface of a square game board 2 made of plywood such as veneer with an adhesive. The decorative sheet 3 is formed by printing a design board surface layer such as a pattern or model name on the back surface of a colorless plate-like surface layer made of nitrate fiber synthetic resin, and a fixing paper such as Kent paper on the back surface of the design board surface layer. Are bonded with an adhesive. Therefore, the fixing sheet 3 is bonded to one surface of the game board 2 with an adhesive, so that the decorative sheet 3 is bonded to the game board 2 to form the design board surface of the game board 1. By attaching the guide rail 4 to the design board surface of the game board 1, the inner side surrounded by the guide rail 4 is formed as the game area A. The guide rail 4 is formed of two parts, a strip-shaped outer rail 5 made of stainless steel and a strip-shaped inner rail 6 made of stainless steel.

  A gap between the outer rail 5 and the inner rail 6 is a launch passage 7 that guides a ball launched from a launch mechanism provided in a gaming machine frame to which the game board 1 is attached to the game area A. In the game area A other than the launch passage 7, a general winning component 8, a starting winning component 9, a variable winning component 10, an out port 11, a windmill 12, a center ornament 13, a symbol display 14, a side lamp 15, and a ball repellent 16 A gaming part such as a game nail 17, which is also called an obstacle nail, is provided. The ball repulsion body 16 is detachably attached to the boundary between the outer rail 5 and the inner rail 6 from the front side of the game board 1. A board decoration 18 is attached to a non-game area outside the guide rail 4 in the game board 1 by a fixing tool 19 such as a nail or a wood screw. The symbol P in FIG. 2 is a sphere. The sphere P flies in the direction of the arrow X1.

  With reference to FIG. 1, the attachment structure of the game board 1 and the ball repulsion body 16 is demonstrated. As shown in FIG. 1 a, the game board 1 is formed with a plurality of recesses 21 as attachment parts that are recessed from the front surface of the game area A into the game board 1. The ball repulsion body 16 is a member made of a material having elasticity such as rubber or elastic synthetic resin. The ball repulsion body 16 has a rotationally symmetric shape with the center B on the center line L1 passing through the plurality of convex portions 22 as a target axis, and two parallel side surfaces 23 facing each other in parallel across the center line L1; 24, one inclined side surface 25 that gradually inclines in the direction of the center line L1 from one parallel side surface 23 toward one end side of the ball repulsion body 16, and a ball repulsion body from the other parallel side surface 24. The other inclined side surface 26 that inclines so as to gradually approach the direction of the center line L1 as it goes to the other end side of 16, and the parallel side surface 23 and the inclined side surface 26 on the other end side of the ball repulsion body 16 are connected. It is an octahedron composed of two front side surfaces 27, one rear side surface 28 connecting the parallel side surface 24 and the inclined side surface 25 on one end side of the ball repulsion body 16, an upper surface 29, and a lower surface 30 parallel to the upper surface 29. Yes. The two inclined side surfaces 25; 26 are parallel to each other. On the lower surface 30 of the ball repulsion body 16, a plurality of convex portions 22 as attachment portions are formed so as to protrude from the lower surface 30 of the ball repulsion body 16 toward the game board 1. The center B is located at the center between the two convex portions 22.

  As shown in FIG. 1b, assuming that the diameter of the concave portion 21 of the game board 1 is D1, and the outer diameter of the convex portion 22 of the ball repulsion body 16 is D2, there is a relationship of D1 <D2. When the depth from the front surface which is the game area A in the concave portion 21 of the game board 1 is H1, and the height from the lower surface 30 in the convex portion 22 of the ball repulsion body 16 is H2, the relationship of H1> H2 is established. The thickness between the upper surface 29 and the lower surface 30 of the ball repulsion body 16 has a dimension of 1/2 or more of the diameter of a sphere used as a game medium in a pachinko machine game. However, the thickness of the ball repelling member 16 is such that the gaming board 1 is attached to the gaming machine frame in a replaceable manner, and the front side of the gaming board 1 is a colorless figure made of light-transmitting glass or synthetic resin of the gaming machine frame. 1 is a range where the upper surface 29 of the ball repulsion body 16 does not contact the front panel 31 when covered with the front panel 31 shown in FIG.

  As shown in FIG. 1 c, according to the structure of the first embodiment, when the ball repulsion body 16 is attached to the game board 1, the convex portion 22 and the concave portion 21 are coupled to each other from the front side of the game area A. Thereby, the ball repulsion body 16 is detachably attached to the game area A. Specifically, when the convex portion 22 is press-fitted into the concave portion 21 from the front side of the game board 1, the lower surface 30 of the ball repellent body 16 comes into contact with the game area A, and the convex portion 22 is a convex portion inside the concave portion 21. Since it stretches to the side surface of the concave portion 21 with elasticity restored to its radially outer side in 22, the holding force of the game board 1 against the ball repulsion body 16 can be ensured. Further, when the game board 1 to which the ball repulsion body 16 is attached is replaceably attached to the gaming machine frame, and the front side of the game board 1 is covered with the front panel 31, the upper surface 29 and the front panel of the ball reaction body 16 are covered. A gap 32 is formed between the back surface of 31. The gap 32 is dimensioned so that a ball flying into the game area A does not enter between the front panel 31 and the game area A.

  According to the structure of the first embodiment, since the ball repulsion body 16 has a thickness of ½ or more of the diameter of the sphere, the projecting dimension of the ball repulsion body 16 from the game area A is along the guide rail 4. 2 is larger than the dimension from the game area A of the ball P shown in FIG. Therefore, as shown in FIG. 2, the ball P flowing in the direction of the arrow X1 along the outer rail 5 collides with the ball repulsion surface formed by one parallel side surface 23 of the ball repulsion body 16 protruding into the game area A. However, since the colliding ball P does not bounce back to the front panel 31 disposed on the front side of the game board 1 and the colliding ball P bounces in contact with the game area A, the front panel of the ball P The collision with 31 can be prevented.

  According to the structure of the first embodiment, since the ball repelling body 16 is soiled or the elasticity of the ball repelling body 16 is deteriorated, when the mounting posture of the ball repelling body 16 is changed, The front panel 31 of the attached gaming machine frame is opened to the front side, and the operator grasps the ball repelling body 16 by hand and pulls it forward, whereby the guide rail 4 of the game board 1, the board decoration 18, and the design in the game area A The ball repulsion body 16 can be easily removed from the game board 1 without damaging the board surface. After that, the operator holds the ball repulsion body 16 removed by hand, and replaces the other parallel side surface 24 as a new ball repulsion surface instead of the ball repulsion surface which is one parallel side surface 23 used so far. By rotating the mounting posture of the ball repulsion body 16 180 degrees in a plane along the game area A of the game board 1 and press-fitting the convex portion 22 of the ball repulsion body 16 into the concave portion 21, a parallel side surface which is a new ball repulsion surface The ball repulsion body 16 is attached to the game board 1 so that 24 collides with the ball. Therefore, it is easy to exchange the mounting posture of the ball repulsion body 16. In this case, since the center B is located at the center between the two convex portions 22, when the parallel side surfaces 23 and 24 are replaced as the ball repelling surfaces, the positions of the ball repelling surfaces with respect to the game area A are the same position. The form of rebounding the ball of the ball repulsion body 16 becomes uniform.

  Further, when the old ball repellent 16 is replaced with a new ball repellent 16, the front panel 31 of the gaming machine frame to which the game board 1 is attached is opened to the front, and the operator holds the old ball repellent 16 by hand. By pulling forward, the old ball repulsion body 16 can be easily removed from the game board 1 without damaging the guide rail 4 of the game board 1, the board decoration 18 and the design board surface in the game area A. Thereafter, the operator holds the new ball repulsion body 16 by hand and presses the convex portion 22 of the new ball repulsion body 16 into the concave portion 21, whereby the new ball repulsion body 16 is attached to the game board 1. Therefore, replacement of the ball repulsion body 16 is easy.
