  In the conventional pachinko machine disclosed in Patent Document 1, the movement of the second and higher stages of the game balls that have flowed in the guide passage from the storage tank is blocked by the swinging body to form one row in one row. Since the current is rectified, a phenomenon called ball biting (or bridge) in which a plurality of game balls are clogged in the guide passage can be prevented. However, in order to level the game balls stacked in two upper and lower stages into a single row by a swinging motion of the swinging body, the rotating shaft of the swinging body whose outer periphery is a cylindrical surface is eccentrically attached to the bowl-shaped member. Further, it is necessary to attach a weight so that the center of gravity is biased to the side opposite to the rotation axis, and there is a problem that the cost is increased by such a complex structure rocking body.

  The present invention has been made in view of the actual situation of the prior art as described above, and its purpose is to simply engage the ball in the bowl-shaped member that guides the game ball discharged from the storage tank to the prize ball payout device. The object is to provide a pachinko machine that can be reliably prevented by the configuration.

In order to achieve the above object, the present invention includes a storage tank capable of storing a large number of game balls, a bowl-shaped member that aligns the game balls discharged from the storage tank and guides the game balls to a discharge port, A pachinko machine comprising a connecting passage extending downward from the discharge port and a prize ball payout device provided on the lower end side of the connection passage, and a predetermined number of game balls being paid out as prize balls by the operation of the prize ball payout device In the above, the bowl-shaped member is a bottom surface portion inclined downwardly from the storage tank toward the discharge port, and a pair of standing upright sides of the bottom surface portion in the width direction to define a guide path for the game ball An upstream end of the restriction wall portion; and a restriction wall portion that extends above the bottom surface portion and gradually narrows the height dimension of the guide passage from the upstream side toward the downstream side. In the specific area located below the side. Through one of the side walls facing, to form a large projection of the upper or lower region length dimension than the game ball 2 pieces of the one of the side wall portion, the projection on the other of said side wall portion And a chamfered taper is formed at both ends in the length direction of the protrusion, and the recess protrudes in the length direction on both the upstream side and the downstream side of the protrusion. It was configured to be .

In the pachinko machine configured as described above, when the game ball discharged from the storage tank flows down to the discharge port in the guide passage of the bowl-shaped member, the upper and lower two stages at the introduction portion (upstream end) of the restriction wall portion With respect to the game balls that overlap, the height of the two game balls that overlap vertically is specified by either one of the upper and lower game balls abutting against the protrusion in the specific area and being shifted in the direction of the depression. Since it is intentionally lowered in the area, the problem that the ball biting occurs at the introduction part of the restriction wall part has a simple configuration.

In the above configuration, when the bowl-shaped member is formed of a synthetic resin molded product and the recess is a notch hole formed in the side wall, the projection and the notch hole can be easily formed by the mold shape for molding the bowl-shaped member. Can be formed.

The pachinko machine of the present invention is longer than two game balls on one side wall portion of a pair of side wall portions facing each other via a guide passage in a specific region below the introduction portion (upstream end) of the restriction wall portion. A projection having a large dimension is formed, and a recess formed on the other side wall is opposed to the projection so as to project in the length direction on both the upstream side and the downstream side with respect to the projection. Since one of the game balls passing in two upper and lower tiers meanders, the height of the two game balls that overlap the upper and lower sides is intentionally lowered. The ball biting can be reliably prevented with a simple configuration, and the game ball discharged from the storage tank can be smoothly guided to the discharge port without causing the ball biting in the middle of the bowl-shaped member.

  The details of the bowl-shaped member 24 will be described with reference to FIGS. 4 to 8. The storage tank 23 is attached to the upper left corner on the back side of the main body frame 2, and the bowl-shaped member 24 is formed from the lower surface of the storage tank 23. A rail is extended toward the upper end of the connecting passage 25. The storage tank 23 is formed in a box shape having an open top surface, and a discharge port (not shown) for discharging the game ball to the bowl-shaped member 24 is provided on the inner bottom surface thereof. The bowl-shaped member 24 has a bottom surface portion 24a that is inclined downwardly from the storage tank 23 toward the connection passage 25, and a pair of side wall portions 24b and 24c that rise from both ends in the width direction (front-rear direction) of the bottom surface portion 24a. A guide passage 26 having a concave longitudinal section is defined by the bottom surface portion 24a and the side wall portions 24b and 24c. The facing distance between the side wall portions 24b and 24c, which is the width dimension of the guide passage 26, is set to be slightly larger than the diameter of the game ball, and the game ball is controlled by the side wall portions 24b and 24c in the width direction while being controlled in the width direction. It flows down from the upstream side of the part 24a to the downstream side. Further, the height dimension of the guide passage 26 is set so as to gradually decrease from the upstream side toward the downstream side, and a discharge port 24d communicating with the connection passage 25 is provided at the downstream end portion of the bottom surface portion 24a. ing.

  A leveling member 27 and a regulating wall portion 28 are attached to the flange-shaped member 24, and the leveling member 27 is prevented from falling off by a pressing member 29. As shown in FIG. 6, the leveling member 27 covers the upper surface opening on the upstream side of the guide passage 26, and the game ball discharged from the storage tank 23 to the guide path 26 of the bowl-shaped member 24 is firstly leveled. 27 flows down to the downstream side while being restricted in height in the vertical direction. The regulation wall portion 28 covers the upper surface opening of the guide passage 26 in a range from the downstream side of the leveling member 27 to the discharge port 24d, and the game ball that has passed through the leveling member 27 is moved vertically by the regulation wall portion 28. It is guided to the discharge port 24d while being regulated in height.

  Here, if the lower part of the introduction part 28a that is the upstream end of the regulation wall part 28 is defined as the specific area S, the height dimension of the guide passage 26 in the specific area S is set to be slightly smaller than two game balls. 7 and 8, a protrusion 24e is formed on one side wall portion 24b facing each other in the specific region S, and a notch (dent) 24f is formed on the other side wall portion 24c. The protrusion 24e is formed in the lower region of the one side wall 24b, and its height dimension is set somewhat smaller than that of one game ball. Further, the length of the protrusion 24e is set to be slightly larger than two game balls, and the upper end of the protrusion 24e and both ends in the length direction are tapered. The notch 24f is formed in the lower region of the other side wall 24c, and its height dimension is set somewhat smaller than one gaming ball, and its length dimension is somewhat smaller than three gaming balls. It is set smaller. That is, in the specific region S located below the introduction portion 28a of the restriction wall portion 28, the upper region of the guide passage 26 extends linearly in parallel with the bottom surface portion 24a, but the bottom region of the guide passage 26 has a bottom surface. Since the protrusion 24e protruding toward the center of the portion 24a and the notch 24f facing the protrusion 24e are formed, the upper region and the lower region of the guide passage 26 are relatively displaced in the width direction.

  In the bowl-shaped member 24 configured as described above, the lower game ball passing through the specific region S abuts against the protrusion 24e with respect to the game ball overlapping the upper and lower two stages at the introduction part 28a of the restriction wall part 28. Therefore, only the lower game ball can meander in the specific area S. Therefore, the centers of the game balls that overlap in the vertical direction are shifted in the width direction of the guide passage 26, and accordingly, the heights of the two upper and lower game balls are intentionally lowered in the specific region S. The game balls that have passed through the specific region S are gradually leveled by the regulation wall portion 28 and guided to the discharge port 24d. After that, it is discharged from the discharge port 24d to the connecting passage 25 and guided to the prize ball payout device 19. When a game ball launched into the game area 9 of the game board 7 during the game enters a general winning opening or a large winning opening of an attacker device, a sprocket (not shown) of the winning ball payout device 19 is driven to rotate. A predetermined number of game balls are paid out as prize balls to the upper tray 13 on the front side of the main body frame 2.

  As described above, in the pachinko machine P according to the present embodiment, the hook-like member 24 that guides the game balls discharged from the storage tank 23 to the discharge port 24d in a line is arranged from the storage tank 23 to the discharge port. A bottom surface portion 24a that slopes downward toward 24d, a pair of side wall portions 24b, 24c that stand up from both ends in the width direction of the bottom surface portion 24a to define a guide path 26 for a game ball, and above the bottom surface portion 24a. And a restriction wall portion 28 that extends and gradually narrows the height dimension of the guide passage 26 from the upstream side toward the downstream side, and the specific region S located below the introduction portion 28 a of the restriction wall portion 28. Thus, the protrusion 24e is formed in the lower region of the one side wall 24b, and the notch 24f facing the protrusion 24e is formed in the lower region of the other side wall 24c. 2 steps up and down Against gaming balls overlapping, it is possible to meander the lower game balls that pass through a particular area S by the projections 24e and the notch 24f. As a result, the centers of the gaming balls that overlap vertically deviate in the width direction of the guide passage 26, and accordingly, the height of the upper and lower two gaming balls is intentionally lowered in the specific region S. Can be smoothly guided to the discharge port 24d without causing the ball engagement at the introduction portion 28a of the regulating wall portion 28.

  In addition, as a configuration in which the upper region and the lower region of the guide passage 26 are relatively displaced in the width direction in the specific region S, a projection 24e is formed on one side wall portion 24b of the flange-shaped member 24, and the projection 24e Opposite notches (dents) 24f are formed in the other side wall 24c, and these protrusions 24e and notches 24f can be easily formed by the mold shape for molding the synthetic resin bowl-like member 24. A ball biting countermeasure can be realized with a simple configuration.

  In the above embodiment, the protrusion 24e and the notch 24f are formed in the lower region of the side walls 24b and 24c facing each other in the specific region S, but the protrusion 24e and the upper region of the side walls 24b and 24c are formed. It is also possible to form a notch 24f. In this case, since the upper game balls that overlap in the upper and lower two stages meander in the specific region S, the centers of the upper and lower two game balls pass between the guide passages 26. Can be shifted in the width direction.
