[Industrial applications]

 The present invention relates to a return ball blocking member for a pachinko machine that blocks a shot ball that has been shot from bouncing off a nail or the like on the playing board surface and returning to the ball guiding path again.

[0002]

[Prior art]

 The pachinko machine is formed by inner and outer ball guide rails and is launched from the ball guide path from the ball striking part to the play board surface to the play board surface. May return to the ball guideway again. When this return ball occurs, it collides with the next ball to be launched in the guideway, which impairs the smooth ball firing operation and hinders the smooth progress of the pachinko game. In particular, with the recent pachinko machines that use a lot of so-called electric appliances, the firing timing has an important meaning, and if this timing is missed, it will cause a great disadvantage to the player.

Therefore, in order to eliminate return balls, measures for preventing ball return have been proposed in JP-B-60-24386, JP-B-3-303138, JP-B-4-28617, and the like.

[0004]

[Problems to be solved by the device]

 By the way, although the respective structures of Jitsukō Sho 60-24386 and Jikkou 4-28617 prevent the inflow of return balls, they do not directly block the discharge end of the ball guideway, so ball return is guaranteed. Cannot be prevented.

On the other hand, in the configuration of Japanese Utility Model Publication No. 3-303138, a tongue made of metal is directly fixed to the discharge end of the guide rail, and a bending action of the tongue causes a check valve-like action. However, because of the bending of the metal piece, the resistance at the time of ball firing is large, it is not possible to fire the ball with proper momentum, and due to bending fatigue over time, the metal tongue piece gradually moves outward. It expands and the launch conditions change later, or it buckles and the check function no longer occurs. Furthermore, there is a problem in that the guide rail needs to be processed and it cannot be retrofitted to the existing base. The present invention aims to eliminate the drawbacks of the conventional configuration.

[0006]

[Means for Solving the Problems]

 The present invention is configured such that one end of a metal tongue piece is fixed to a holding base having a shaft hole through which a support shaft is inserted and a weight portion is provided below the metal tongue piece, and the metal tongue piece is projected upward. Beside the discharge end of the ball guiding path formed from the inner and outer ball guiding rails from the ball striking part to the playing board surface, it is rotatably supported by the support shaft and guides the metal tongue by the action of the weight. The present invention relates to a return ball blocking member of a pachinko machine that is held in an upright position that shields the discharge end of the guide rail.

[0007]

[Action]

 In the steady state, the return ball blocking member is supported by the support shaft, and the weight of the weight causes the blocking piece to stand upright to block the discharge end of the ball guiding path. In this state, when a ball is fired, it rotates clockwise around the above-mentioned spindle to enable the ball to be fired, and then the return ball blocking member immediately returns to the blocking position by its own weight. For this reason, balls that bounce back on the play board surface and fly to the discharge end side of the ball guide path collide with the blocking piece, but the return ball blocking member abuts the guide rail and maintains its shielded state. The ball cannot flow into the taxiway, thus preventing the ball from returning and bouncing back into the playing board.

[0008]

【Example】

 An embodiment of the present invention will be described with reference to the accompanying drawings. FIG. 1 shows a pachinko machine 1, on the lower part of which an operating handle for launching a launching mallet, a saucer (not shown), etc. are arranged, and ball guide rails inside and outside so as to surround the play board surface 2. 4 are provided. The inner ball guide rail 4 extends to the upper left portion of the play board surface 2 and is pressed by the launch mallet between the ball guide rails 3 and 4 to the side of the play board surface 2 from the ball hitting portion. A ball guiding path 5 that leads to the side is formed. On the play board surface 2, various winning openings such as the winning device 6 at the center and nails are arranged.

Next, the structure of the return ball blocking member 10 according to the present invention will be described.

Reference numeral 11 denotes a holding base made of a synthetic resin material, which connects a cylindrical support shaft portion 12 having a shaft hole 13 inside and a weight portion 14 into which a weight 15 is fitted. An L-shaped holding arm 16 is projected from the weight portion 14, and a holding groove 18 is formed between the holding arm 16 and the base portion 17. A circular holding edge 19 is formed on the tip of the holding arm 16, and a circular holding groove 21 is formed on the base end of the holding groove 18. As shown in FIG. 2, the holding groove 18 is open to the front side and is shielded from the back side.

Further, a triangular holding head portion 22 is formed on the cylindrical support shaft portion 12, and a right side surface is formed along the center of the holding groove 18, and a top surface is inclined to the left side. This is the inner surface 23.

The holding substrate 11 having such a structure is made of a synthetic resin material, rubber, metal or the like. In addition, the weight portion 14 can generate a weight action by itself without fitting a weight.

In the holding groove 18 of the holding base 11, a metal tongue piece 25 made of a thin plate is fitted into the circular holding groove 21 at the base end of the cylindrical portion 26 and protrudes upward. The metal tongue piece 25 is fitted from the front surface which is the opening side of the holding groove 18. In such a fitted state, the metal tongue piece 25 is supported by the holding projection edge 20 on the right side surface on the base end side and by the cylindrical support shaft portion 12 on the left side. In order to prevent the lateral displacement of the metal tongue piece 25 even more completely, as shown by the chain line in FIG. 4, a locking projection 27 is projected from the front edge of the right side surface of the holding head 22, You may make it contact | abut on the front edge of this metal tongue piece 25. The metal tongue 25 may be shortened so that the distance between the tip of the metal tongue 25 and the ball guiding rail 4 is within the diameter of the pachinko ball.

The return ball blocking member 10 is mounted at the end edge position of the ball guiding rail 4 by inserting the support shaft 24 into the shaft hole 13. The support shaft 24 can use a nail, and can be easily attached by directly pressing the support shaft 24 against the play board surface 2. Then, in this mounted state, the metal tongue piece 25 is held in the upright position by the action of the weight 15 and shields the discharge end of the ball guiding path 5 as shown in FIG. The mounting position is such that the guide surface 23 substantially coincides with the extension line from the edge of the ball guiding rail 4. As a result, the guide surface 23 guides the shot ball to the game board surface 2 in the vicinity of the discharge end of the ball guide path 5.

In such a structure, when the ball x is fired from the ball striking portion by the handle operation, guided by the ball guiding path 5, and emitted from the discharge end of the ball guiding path 5, it is shown in FIG. As described above, the return ball blocking member 10 contacts the metal tongue piece 25 and rotates clockwise about the support shaft 24. As a result, the shot ball x is smoothly discharged. In the tilted return ball blocking member 10, the weight portion 14 contacts the inner surface of the ball guiding rail 4, the tilt angle is limited, and the ball returns to its original position by its own weight after passing the ball.

In this operation, the return ball blocking member 10 is in a fixed position by its own weight with the support shaft 24 as a fulcrum, and tilts by the operation of the pendulum by the weight 15, so the resistance at the time of ball firing is extremely small. The ball can be smoothly ejected without requiring a large hitting force in the ball hitting portion, and the return ball blocking member 10 itself is not subjected to excessive force.

On the other hand, the balls shot into the play board surface 2 are struck along the inner surface of the ball guide rail 3 and are attached to the stopper 30 and nails arranged on the upper right of the ball guide rail 3. It may bounce back and return to the discharge end side of the ball guideway 5. As shown in FIG. 6, the return ball y hits the metal tongue piece 25 and urges the return ball blocking member 10 counterclockwise. Since only the rotation to the position in contact with the inner surface of the rail 3 is allowed, the discharge end of the ball guiding path 5 is kept in the shielded state by the metal tongue piece 25, and the ball y is moved inside the ball guiding path 5. It bounces back without returning to and is released to the game board surface 2 again.

In this way, the return ball blocking member 10 acts as a check valve by the metal tongue piece 25, whereby the return ball y does not return and the next ball firing is not hindered, and the ball is smoothly moved. Are fired one after another. Therefore, for example, even when the opening / closing blade of the winning device 6 is in an open state and the timing of hitting a ball is required, the ball is smoothly radiated and the disadvantage of the player due to the returning ball is eliminated.

[0019]

[Effect of device]

 As described above, the return ball blocking member 10 of the present invention is provided with the metal tongue piece 25 which is kept upright by the weight portion 14 and shields the discharge end of the ball guide path 5, and the return ball blocking member 10 is provided by the metal tongue piece 25. Since it is designed to shut off, it is possible to reliably prevent the occurrence of return balls, maintain the proper timing of ball firing, and supplement the smooth progress of pachinko games. In the normal state, the spindle 24 is used as a fulcrum to take a fixed position due to its own weight, and when the ball is fired, it tilts due to the action of the pendulum. It is possible to secure a smooth ball emission without requiring any force, and since no excessive force is applied to the return ball blocking member 10 itself, it does not cause deformation or buckling due to long-term use, and is excellent in durability. . Furthermore, it is possible to directly attach a nail serving as the support shaft 24 to the game board surface 2 and easily attach it, and it is possible to apply it to an existing stand without the need for processing a guide rail. is there.
