Description

  The present invention relates to a ball guiding and dropping device for a gaming machine configured to guide a ball laterally on a vertical wall and drop the ball at a predetermined position. In this specification, the vertical wall means a wall body provided substantially perpendicular to the installation surface of the gaming machine, and the lateral direction means a direction substantially horizontal to the installation surface. The concept is wider than the horizontal direction.

  In describing the prior art, drawings of embodiments of the present invention will be used. As shown in FIG. 1 to FIG. 3, a pachinko machine P having a ball path called a warp route for guiding a game ball B to a start winning opening 8 in a center accessory device A is known. That is, the decorative member 15 constituting the center accessory device A protrudes from the board surface of the game board 1 to the near side, and the respective warp inlets 16 for allowing the game balls B to enter are opened on both sides thereof. . A game ball B that has entered the center accessory device A from any one of the warp inlets 16 passes through the warp passage 17 and constitutes a pair of second shelves constituting the shelf device T disposed in the center accessory device A. It enters any one of the shelf parts 22 and rolls its upper surface at a predetermined speed. When the traveling speed of the game ball B at this time is close to a predetermined value, the game ball B is a portion of the top portion 24 provided between the pair of first shelf portions 22 and is provided on the back side thereof. The ball falls from the ball drop opening 24a and enters the start winning opening 8 with a high probability.

  In the conventional pachinko machine P, a magnet plate (not shown) is mounted horizontally on the shelf device T, and the game ball B is guided to the ball drop opening 24a of the top 24 by the magnetic force of the magnet plate. There is a sphere guidance device of construction. In this apparatus, the game ball B is rolled while being attracted to the bottom surface of the magnet plate in a suspended state, and the magnetic force is extinguished and dropped immediately above the ball drop port 24a. However, in this apparatus, since the game ball B is sucked in a suspended state, the game ball B may not fall. For this reason, the interest of a player is reduced instead.

  In view of the above-described problems, an object of the present invention is to increase the interest of a player.

The invention of means 1 for solving the above problems is as follows:
A shelf device is provided in the game area of the game board,
The shelf apparatus is
A rear wall parallel to the game area of the game board and located behind the game area;
A ball introduction part capable of rolling a ball introduced from the game area of the game board in the thickness direction of the game board to the back end on the back wall side;
A sphere drop opening provided in front of the back wall portion in a lateral direction away from the sphere introduction portion;
Protruding in the shape of a shelf on the front surface of the back wall portion to enable rolling of the sphere from the sphere introduction portion to the sphere drop opening, and a downward inclined region with the back end of the sphere introduction portion as a start end portion In a gaming machine having a shelf board part provided with an obstacle region that makes it difficult to reach the ball dropping port in the middle of the path to the ball dropping port,
The shelf apparatus includes a ball guiding and dropping device capable of rolling a sphere from the sphere introduction part to the sphere dropping port separately from the shelf board part,
The ball guided drop device is:
In order to form a sphere passage from the back end of the sphere introduction part to the sphere drop port through the obstacle area of the shelf board part, the front side of the back wall part is looser than the start end part of the shelf board part. A ball support guide formed with a downward slope;
A magnet body formed on the back side of the back wall portion corresponding to the ball support guide body,
The sphere support guide body is in a side view step shape that is in contact with substantially one point of the lower half of the sphere in a state where the sphere is in contact with the back wall and cannot hold the sphere in a vertical plane alone.
The magnet body is in and alone can attract the ball to the rear wall portion is arranged horizontally with respect to the ball support guide member of the set Rutotomoni down inclined force that can not hold the ball in a vertical plane As the sphere descends along the sphere support guide body, the position shifts and the magnetic force acting on the sphere decreases ,
On the other hand, the sphere support guide body and the magnet body can be held by the magnetic force of the magnet body that attracts the sphere to the back wall portion without being over the step of the sphere support guide body. In this way, the sphere rolls along the downward slope of the sphere support guide so that it can reach the sphere drop opening over the obstacle area of the shelf, and finally the sphere support guide It is characterized by being able to come off the ball and enter the ball drop opening.

  During the game, a sphere is introduced into the part of the sphere passage that constitutes the sphere guided drop device. When the initial velocity of the sphere is close to a predetermined value and the traveling direction of the sphere at the time of introduction is substantially along the guiding direction of the sphere support guide body, the sphere has a straight traveling force. A plurality of elements including the attracting force to the back side by the magnet body and the supporting force of the ball support guide are balanced, and are guided to a predetermined position and dropped. Since the player can visually recognize the movement of the ball that is guided by the support guide and travels through the ball passage, the interest in the game is enhanced.

  The invention of the means 2 is based on the invention described in the means 1, and the ball support guides are arranged symmetrically on the back wall of the shelf apparatus, and the balance is lost at the center. It is characterized in that a ball dropping part for dropping the ball is provided. In this invention, since the ball dropping part is provided, the sphere guided by the left and right sphere support guides loses balance at the center part in the lateral direction of the rear wall of the shelf apparatus and almost certainly falls. For this reason, a player's expectation is raised.

  The invention of the means 3 is based on the invention described in the means 2, and the ball dropping part is configured by omitting the central part of the ball support guide body arranged symmetrically on the back wall of the shelf board device. It is characterized by that.

  The invention described in the means 4 is based on the invention described in the means 2, and the ball dropping part is configured by omitting the central part of the magnet body arranged laterally on the back wall of the shelf device. It is characterized by that. In this invention, the sphere dropping part is configured by removing the central part of the magnet body so that the magnetic force of the magnet body does not act on the sphere. Therefore, the configuration is simple.

  The invention described in means 5 is based on the invention described in any one of means 1 to 4, wherein the magnet body is arranged horizontally, and the guide end of the ball support guide body is lowered. It is characterized by being slightly inclined. In the present invention, the ball support guide is disposed slightly inclined with respect to the horizontally disposed magnet body. For this reason, as the sphere approaches the guide end of the sphere support guide body, the attractive force received from the magnet body decreases, loses balance during traveling, and easily falls. By doing so, it is possible to drop the ball in the middle of traveling with a simple configuration.

  The invention described in means 6 is characterized in that, on the premise of the invention described in any one of means 1 to 5, the magnet body is configured to approach and separate from the spherical passage. By doing so, the strength of the magnetic force acting on the sphere can be changed. That is, by controlling the approach / separation of the magnet body, the action of rolling the ball or dropping it halfway can be realized with a simple configuration.

  The invention described in the means 7 is based on the invention described in any one of the means 1 to 6, and the sphere support guide body has a protrusion whose protrusion length from the vertical wall is smaller than the radius of the sphere in the cross section thereof. It is characterized by being an article. In this invention, since the protrusion length of the protrusion is short, the protrusion is not conspicuous, and the player can feel as if the ball is running in the air, further enhancing the player's interest. It is done.

  The invention described in means 8 is characterized in that, on the premise of the invention described in any one of means 1 to 6, the sphere support guide body is a groove portion whose width is smaller than the outer diameter of the sphere. In this invention, since it is only necessary to provide the groove portion as the ball support guide body, the configuration is simplified.

  In the gaming machine of the present invention, the player can visually recognize the state in which the ball is guided, and the interest of the game is enhanced.

Then, when a plurality of symbols when stopped are in a specific display mode, the “big hit game” is started. Then, the lid body of the big prize opening 9 falls to the near side, and the big prize opening 9 is opened until a predetermined time (for example, 30 seconds) or a predetermined number (for example, 10) has been won. And even after the special winning opening 9 is closed by the standing of the lid, a ball (winning ball) received through the special winning opening 9 passes through an internal special winning opening (not shown). Again, the lid body falls to the near side, the big winning opening 9 is opened, and the “big hit game” is repeated up to 16 times (round). In FIG. 1, reference numeral 14 denotes an out port for collecting the game balls B that have not won any winning port.

  As shown in FIGS. 1 and 2, a mountain-shaped decorative member 15 is attached to the upper half of the center accessory device A so as to protrude from the game board 1. A warp inlet 16 is formed on the outer surface. Further, a warp passage 17 is formed inside the pair of left and right vertical members 15a constituting the decorative member 15, and a warp outlet 18 is formed on the inner surface of the lower end portion of each vertical member 15a. .

Further, the left and right end portions of the pair of first shelf portions 22 are provided at the ball introduction portion (the portion that drops the game ball B that has entered the warp inlet 16 and introduces it into the ball passage R). ) And a top portion 24 having a slightly convex arc shape is formed at the joint portion of the pair of first shelf portions 22. On the back side of the top portion 24, a ball drop opening 24a for dropping the game ball B is provided. The ball drop opening 24 a communicates with the recess 23 a of the second shelf 23 by a ball communication path 25 provided below the top 24. The configuration of the shelf board device T described above, except for the portion of the sphere derived dropping device S ₁ to be described later, it is substantially the same as the conventional.

  Next, the movement of the game ball B in the shelf board device T will be described. The game ball B introduced from the warp inlet 16 into the shelf device T rolls on the upper surface of any of the first shelf portions 22. When the traveling speed of the game ball B at this time is larger than a predetermined value, the game ball B rolling on the first shelf 22 on one side jumps over the ball drop opening 24a and the first shelf on the other side. It enters the portion 22, where the traveling speed is lowered while reciprocating, and falls from the recess 22 a to the second shelf 23. And it is discharged to the game area 4 of the game board 1 as it is. Similarly, when the traveling speed of the game ball B is smaller than the predetermined value, the gaming ball B gradually lowers the traveling speed while reciprocating on the upper surface of the first shelf 22 on one side, From 22a, it falls to the second shelf part 23 and is released to the game area 4 of the game board 1 as it is. When the traveling speed of the game ball B is close to a predetermined value, the game ball B riding on the top 24 falls from the ball drop opening 24a to the recess 23a of the second shelf 23 and starts with high probability. Enter the winning entrance 8.

Next, a description will be given sphere induced drop apparatus S ₁ of the first embodiment of the present invention. 3 is a front view of the ball guided dropping device S ₁ of the first embodiment, FIG. 4 is also a plan view, FIG. 5 is a side sectional view, FIG. 6 is a perspective view from the front side, and FIG. FIG. This ball guiding and dropping device S ₁ is disposed in the above-described shelf device T, and is a portion of the ball passage R formed on the front side (player side) of the rear wall portion 21 of the frame 19. projecting from the, and projections 26 for partial support game balls B rolling travel, the magnet plate M ₁ a pair (two) which is arranged on the rear side of the ball passage R, the pair of magnets a magnet plate holding plate 27 plate M ₁ is attached, and a close-spacing device K for close-spaced to the rear portion of the rear wall portion 21. The pair of magnet plates M ₁ in the present embodiment are both multipolar magnetized permanent magnet.

As shown in FIG. 3 to FIG. 6, a pair of protrusions 26 project from the rear wall portion 21 of the frame body 19 when viewed from the front in a state of being slightly inclined from both ends to the center. Has been. The cross-sectional shape of each protrusion 26 is substantially triangular, and the protruding length thereof is much shorter than the radius of the game ball B. In other words, in a state where the game ball B is in contact with the back wall 21 of the frame body 19 and is partially supported by each protrusion 26, the position of the center of gravity of the game ball B in a side view is the position of each protrusion 26. Located in front of the tip. Thus, the game balls B rolling travels while in contact with the rear wall portion 21 of the frame 19, if the magnetic force of the magnet plate M ₁ is not applied, is the recreation sphere B, is held as it is It never happens, and it always falls to the near side. In addition, the start ends of the protrusions 26 are continuous with the ball introduction portions 19 a provided at both ends of the frame body 19, and the end portions 26 a are the tops of the pair of first shelf plates 22. 24 is arranged immediately above the ball drop opening 24 a formed in the head 24. Beginning the arranged balls of each protrusion 26 is attracted by the magnetic force of the magnet plate M ₁ comes into contact with the rear wall portion 21 of the frame 19, roll travels while being partially supported by the respective protrusions 26, It is guided to the part of the ball drop opening 24a of the top 24.

Next, the approach / separation device K will be described. As shown in FIGS. 4 to 7, on the back side of the frame body 19, a pair of magnet plates M <b> ₁ is approached / separated to approach / separate the back surface portion of the back wall portion 21 of the frame body 19. A device K is provided. The approaching / separating device K includes a magnet plate holding plate 27 that is rotatably mounted in a vertical plane by a rotation fulcrum pin 28 disposed below the back side of the shelf device T, and reciprocatingly rotates the magnet plate holding plate 27. It is comprised from the drive motor 29 for making it move. That is, the length of the magnet plate holding plate 27 in the horizontal direction is slightly shorter than the length of the frame body 19, and the leg portions 27 a and 27 b are extended downward at both ends and substantially the center. ing. The rotation fulcrum pin 28 is inserted into the lower ends of the leg portions 27a and 27b, and the magnet plate holding plate 27 rotates in the vertical plane around the axis of the rotation fulcrum pin 28. It is possible to move. Further, of the leg portions 27a and 27b, the two leg portions 27a suspended from both ends of the magnet plate holding plate 27 are bent backward at approximately 90 degrees at the portion where the rotation fulcrum pin 28 is inserted. Each balancer 31 (weight) is attached to the front end portion thereof. Due to these balancers 31, the magnet plate holding plate 27 is constantly exerted in a direction in which the magnet plate holding plate 27 is tilted toward the back side.
Wherein the front portion of the magnetic plate holding plate 27 (the back portion and the opposing portion of the rear wall portion 21 of the frame 19), by two state magnetic plate M ₁ is one row, in the same height position, substantially horizontal Is pasted. Each magnet plate M ₁ is (in the rear wall portion 21, the portion excluding the sphere inlet portion 19a of the frame 19) near the both end portions of the rear wall 21 of the frame body 19 from the pair of first shelf plate part 22 It is arrange | positioned over the vicinity of the top part 24 between. Therefore, the portion just above the top portion 24 of the ball passage R, no magnetic region Q (region of magnetic force beyond the magnetic plate M ₁₎ is provided. In the case of the ball guided drop device S ₁ of the first embodiment, the size of the magnetically insensitive region Q is about two game balls B. When each magnet plate M ₁ comes close to the back surface portion of the back wall portion 21 of the frame body 19, their magnetic force acts on the game ball B beyond the back wall portion 21. The strength of the magnetic force becomes the strongest when the magnet plate holding plate 27 is substantially in close contact with the back surface portion of the back wall portion 21 of the frame body 19, and the strength at that time is arranged in the spherical passage R, The game balls B that roll while being partially supported by the protrusions 26 are not dropped. As a result, ball passage R in arranged game ball B is in a state in which a plurality of elements including a magnetic force of the pair of magnet plates M _1, and a portion supporting force of each protrusion 26 is balanced, the projections 26 If the balance is lost for any reason, it will fall at that position.

As shown in FIGS. 4 to 7, a drive motor 29 is attached to the back side of the magnet plate holding plate 27 with its motor shaft 29 a erected upward. A spiral disc-like cam plate 32 is attached to the upper end portion of the motor shaft 29a, and the length of the cam radius 32a is gradually changed. When the motor shaft 29a of the drive motor 29 is continuously rotated in a predetermined direction and the cam radius 32a is gradually increased, the magnet plate holding plate 27 rotates to the near side about the axis of the rotation fulcrum pin 28. Then, it approaches the back surface portion of the back wall portion 21 of the frame body 19. When the cam radius 32 a of the cam plate 32 in contact with the magnet plate holding plate 27 is maximized, the pair of magnet plates M ₁ are almost in close contact with the back surface portion of the back wall portion 21 of the frame body 19. Further, when the cam radius 32 a of the cam plate 32 is minimized, the magnet plate holding plate 27 is rotated to the back side by each balancer 31, and the pair of magnet plates M ₁ is the rear wall portion 21 of the frame body 19. Separated from the back of the. At this time, the magnetic force of the pair of magnet plates M ₁ is no longer applied to the game ball B. In this way, the pair of magnet plates M ₁ attached to the magnet plate holding plate 27 approaches and separates from the rear wall portion 21 of the frame body 19.

As shown in FIG. 8, the pair of magnet plates M <b> ₁ in the present embodiment is composed of multipolar magnetized magnets (permanent magnets). That is, as shown in (b) of FIG. 8, each magnet plate M _1, the rear portion and the opposing surface of the rear wall 21 of the frame 19, N poles and S poles are formed alternately ing. By doing so, the surface of each magnet plate M _1, as shown in (b) of FIG. 8, the magnetic field lines 30 respectively generated between each N-pole and the S pole. Therefore, the entire length of each magnet plate M _1, it is possible to generate a constant magnetic force, the movement of the game balls B disposed in ball passage R can be stabilized. If the magnet plates M ₁ is, if made of ordinary two-pole magnetized magnet, the magnetic force of the both end portions of each magnet plate M ₁ is particularly strong, difficult to generate a constant force over the entire length And the movement of the game ball B becomes unstable.

Next is a description of the operation of the ball-induced drop apparatus S ₁ according to the present invention. In order to simplify the explanation, it is assumed that the pair of magnet plates M ₁ are in close contact with the back surface portion of the back wall portion 21 of the frame body 19. The strength of the magnetic force acting on the game ball B is such that the game ball B that rolls while being partially supported by each protrusion 26 is not dropped. As shown in FIG. 1 and FIG. 2, the game ball B that is discharged to the game area 4 of the pachinko machine P through the ball launching passage 5 and enters the warp inlet 16 passes through the warp passage 17 and enters the warp outlet 18. To the sphere introducing portion 19a of the frame body 19 from above. Since the ball introduction portion 19a is attached to be inclined downward toward the back side, the game ball B moves toward the back wall portion 21 of the frame body 19 while rolling.

Of the game balls B that have fallen from the warp outlet 18 to the ball introduction part 19a of the frame body 19, most of the game balls B have dropped to any one of the first shelf parts 22 constituting the shelf apparatus T as they are. Rotate and run on the upper surface of each first shelf portion 22. Depending on the traveling speed at that time, it enters the ball drop opening 24a of the top 24 or falls from the concave portion 22a of any of the first shelf portions 22 to the second shelf portion 23. However, some of the game balls B that have fallen on the ball introduction portion 19a travel toward the back wall portion 21 of the frame body 19 as they are. Then, contact with the rear wall portion 21 is sucked by a pair of magnetic force of the magnet plate M _1, is partially supported by the respective protrusions 26, it attempts to rolling travel along its longitudinal direction.

That is, disposed in the ball passage R game ball B, as shown in (b) of FIG. 9, a plurality of elements including a magnetic force of the pair of magnet plates M _1, and a portion supporting force of each ridge 26 Are guided along the longitudinal direction of each protrusion 26 in a balanced state. Here, a pair of magnet plates M _1, compared Disposed substantially horizontally, each protrusion 26 is mounted in an inclined state downward. For this reason, the strength of the magnetic force acting on the game ball B that rolls gradually decreases as the game ball B approaches the end portion 26 a of each protrusion 26. Moreover, among then if the pair of magnet plates M ₁ on the rear wall 21 of the frame 19, in the portion immediately above the ball drop opening 24a, provided with a large non-magnetic region Q than the outer diameter of the game ball B Yes. For this reason, when the game ball B reaches the end portion 26a of each protrusion 26, the magnetic force disappears, and the game ball B loses balance and falls to the ball drop opening 24a as it is. Then, it passes through the ball passage 25 and falls into the recess 23a of the second shelf 23, and enters the start winning opening 8 with a high probability.

As described above, in the ball guided dropping device S ₁ according to the present invention, a part of the game ball B that has entered the warp inlet 16 is attracted by the magnetic force of the pair of magnet plates M ₁ , and the protrusions 26 are left as they are. The game ball B can be caused to roll while being supported by the ball drop port 24a provided in the top 24 of the pair of first shelf boards 22. At this time, the game ball B which rolls traveling, the traveling speed of the recreation sphere B (inertial force), and a suction force to the rear side by the pair of magnet plates M _1, part supporting force by the pair of projections 26 Are working in a balanced state. The game ball B passes through the ball communication path 25 and enters the start winning opening 8 with a high probability. However, the warp enters gaming balls B to the inlet 16 is disposed in a suction state in the sphere passage R by a pair of magnet plates M _1, whether derived directly up ball drop opening 24a, a sphere from the warp entrance 16 It is determined by the travel speed, travel direction, etc. of the game ball B immediately after falling on the introduction part 19a, and not all of the game balls B that have entered the warp inlet 16 are guided to the ball drop opening 24a. . For this reason, the player can have a sense of expectation that the game ball B may enter the start winning opening 8. Further, since the player can visually recognize the state in which the game ball B is partially supported by each protrusion 26 and rolls, the interest in the game is enhanced.

Also, not all of the game balls B that roll in the ball path R are rolling as they are, and may fall on the way for some reason. For example, the traveling speed of the game balls B immediately after falling to the ball inlet portion 19a is sucked, if it was intended predetermined size, ball passage R to arranged the game balls B are a pair of magnet plates M ₁ Can be done. However, when the traveling direction deviates from the predetermined traveling direction, the game ball B is removed from the ball path R. Then, the suction force of the pair of magnet plates M ₁ is reduced. That is, the three elements described above (the running speed of the game ball B, the attraction force of the magnet plate M _1, part supporting force of the projections 26) is lost balanced by, the recreation ball B is in the middle of the ball passage R Fall.

Next, the spheres induced drop apparatus S _1, operation will be described in the case of actuating the approach-separation device K. In this case, the motor shaft 29a of the drive motor 29 constituting the approach / separation device K is continuously rotated, and the magnet plate holding plate 27 is reciprocally rotated in the vertical plane around the axis of the rotation fulcrum pin 28. . Then, the pair of magnet plates M ₁ attached to the magnet plate holding plate 27 repeats the operation of approaching and separating from the back wall portion 21 of the frame body 19. As a result, for example, even if the game ball B is rolling while being partially supported by the protrusion 26, when the magnet plate holding plate 27 is separated, as shown in FIG. The magnetic force of M ₁ does not act on the game ball B, and the game ball B falls in the middle of the ridge 26. In this way, the game ball B arranged in the ball passage R is not necessarily caused to roll to the ball drop opening 24a, thereby further enhancing the interest of the player. This approach / separation device K may be always operated, or may be operated only when the special symbol display device 7 displays a specific symbol.

Magnet plate M ₁ constituting the spherical induced drop apparatus S ₁ as described above, the two things is when affixed in a straight line with a non-magnetic region Q of predetermined length. However, the magnet plate M ₂ and one, but may be in the form of cut out junction of each protrusion 33. Next, the spheres induced fall device S ₂ of this embodiment (second embodiment) will be described. As shown in FIG. 10, in the magnet plate holding plate 27, the magnet plate M < _b > ₂ is horizontally attached to the surface facing the back wall portion 21 of the frame body 19 over substantially the entire length. Then, the the rear wall portion 21, a pair of projections 33 in much the same way as a pair of projections 26 which constitutes the sphere inductive drop apparatus S ₁ of the first embodiment is inclined downwardly toward the central portion Projected in the form. A large cutout 34 having a width wider than the outer diameter of the game ball B is formed at a portion corresponding to the joint between the pair of protrusions 33.

The sucked by the magnetic force of the magnet plate M _2, either induced in the protrusion 33 gaming ball B which rolls running, reaches the end portion 33a of the projections 33, the magnet plate M in the recreation sphere B _Although the magnetic force of ₂ is acting, the force that partially supports the game ball B disappears, so the game ball B falls due to its own weight. At this time, since the game ball B rolls along the longitudinal direction of each protrusion 33, a horizontal velocity component acts on the ball drop opening 24 a provided on the top 24 as it is. Enter the start winning opening 8 through the ball communication path 25. Also in the case of the ball guided drop device S ₂ of this embodiment, the magnetic plate holding plate 27 is attached to the frame body 19 by operating the approach / separation device K as in the ball guided drop device S _{1 of} the first embodiment. The player's interest can be enhanced by approaching / separating the back surface portion of the back wall portion 21.

In each of the first and second embodiments described above, the protrusions 26 and 33 are both inclined and attached, whereas the corresponding magnet plates M ₁ and M ₂ are both Installed horizontally. However, various shapes other than those in the first and second embodiments described above can be considered for the shapes of the protrusions 26 and 33 and the magnetic plates M ₁ and M ₂ and the positional relationship between them. For example, the magnet plates M ₁ and M ₂ may be inclined and arranged so as to be parallel to the ridges 26 and 33. In this case, the game balls B that are guided by being partially supported by the ridges 26 and 33 are affected by the magnetic force of the magnetic plates M ₁ and M ₂ up to the end portions 26 a and 33 a of the ridges 26 and 33. The game ball B is difficult to fall. Also, the magnet plate _M 1, _{M 2} may be either is arranged horizontally also in the ridges 26 and 33. In this case, since the vertical velocity component does not act on the game ball B, the game ball B is likely to stop halfway. Furthermore, the protrusion length from the back wall part 21 of the frame 19 in each protrusion 26, 33 is gradually changed (for example, gradually narrowed or conversely widened), or each protrusion 26, 33. The upper surface of the film may be bent in a convex shape. By doing so, a change is brought about in the motion of the game ball B rolling in the ball path R, and the interest of the player is further enhanced.

Next, a description will be given sphere induced fall device S ₃ of the third embodiment. As shown in FIGS. 11 and 12, the sphere-induced fall device S ₃ of this embodiment, the rear wall 21 of the frame 19, a groove portion 35 slightly narrower than the outer diameter of the game ball B is in the central portion It is provided in a form inclined downward. An approach / separation device K having the same configuration as described above is disposed on the back side of the back wall portion 21 of the frame body 19. And, the magnetic plate holding plate 27, so as to cover the said groove 35, is attached a pair of magnet plates M _3. The game ball B attracted by the magnetic force of the pair of magnet plates M ₃ rolls along the longitudinal direction of the groove 35 while being fitted in the groove 35. In the sphere induced fall device S ₃ of this embodiment, because it requires the rear wall 21 of the frame 19 by providing the groove section 35 with a predetermined width, there is an advantage that the structure is simplified. The shape of the magnet plate M ₃ and the groove 35, the positional relationship, the various ones is assumed, as in the case of the sphere-induced fall device S _1, S ₂ of the first and second embodiments It is.

In each of the above-described embodiments, one game ball B rolls along the ball path R. However, there may be two or more game balls B that roll in the ball path R. For example, when two game balls B are partially supported by one of the ridges 26 and roll in a substantially continuous state, and the subsequent game ball B collides with the preceding game ball B on the way think of. In this case, when the preceding game ball B jumps up or changes its running speed due to the rear-end collision, the balance of the magnetic force acting on each game ball B, the partial support force of each protrusion 26, etc. is lost. each game ball B is dropped or the front side in the middle thereof, the traveling speed by being rear-end collision is reduced, it is sucked by a pair of magnetic force of the magnet plate M _1, or stop it.

In each of the above-described embodiments, a case where the game ball B that has entered the portion of the shelf device T from the warp inlet 16 rolls in the ball path R, is guided to the ball drop opening 24a, and enters the start winning opening 8 is described. did. However, the game ball B may be guided to a part other than the ball drop opening 24a of the shelf board device T (for example, directly guided to the start winning opening 8). As described above, the ball guided dropping devices S _{1 to} S ₃ according to the present invention may be arranged in any part (for example, a part other than the vertical wall) of the gaming machine (pachinko machine P). Of course, the game machine may be other than the pachinko machine P as long as it uses a game ball B or the like (coin or the like).

Each magnetic plate M ₁ in each embodiment described above are those made of permanent magnets. For this reason, there is an advantage that maintenance and inspection are easy. However, it may be made of an electromagnet.

Also, approach and separation device K in the above embodiments, a magnet plate holding plate 27 in which a pair of magnet plates M ₁ is attached is rotated, the pair of magnet plates M _1, the rear wall portion of the frame 19 In this configuration, the strength of the magnetic force acting on the game ball B is changed by approaching / separating 21. However, if slide the pair of magnet plates M ₁ vertically by or is rotated by one end to a fulcrum, it may be changed in intensity of the magnetic force acting on the game ball B.
