JP 2010-201229 A

  By the way, in the pachinko gaming machine, a game ball with a thread in which one end side of a thread is fixed to the game ball is fired and rolled into the game area, and the game ball with a thread is moved to the game area with the other end of the thread. For example, the player may perform an illegal act such as illegally acquiring a prize ball.

  For this reason, in recent years, it has been required to take measures to prevent the above-described fraud.

  Therefore, in view of such a demand, an object of the present invention is to provide a pachinko gaming machine that uses a ball return prevention device effectively to prevent an illegal act using a game ball with a thread. .

In solving the above-mentioned problems, the pachinko gaming machine according to the present invention, according to claim 1,
Game board (10),
An outer rail (22) standing on the board surface (11) of the game board, and at least a part of the outer rail provided on the board surface of the game board at a predetermined distance from the outer rail inside the outer rail An inner rail (21) that forms a ball guide passage for guiding the game ball between the upper rail, an apparatus main body (110) provided on the board surface of the game board at or near the upper end of the inner rail, and a tilting member And a ball return prevention device (100) having (120).

In the ball return prevention device, the tilting member is
An axially rotating member (120c) that is rotatably supported by the apparatus body so as to be perpendicular to the board surface of the game board;
An upper tilting portion (120a) extending from the shaft-like rotating member in the direction of guiding the game ball by the ball guide passage;
A lower tilting part (120b) extending in a direction opposite to the guide direction with respect to the shaft-like rotating member,
When the tilting member is at the first tilting position tilted to the outer rail side with respect to the upper end portion of the inner rail at the upper tilting portion, the lower tilting portion is positioned outside the upper end portion of the inner rail. The lower tilting portion is positioned at the second tilting position that is positioned on the opposite side of the rail and is tilted to the opposite side of the outer rail from the upper end of the inner rail at the upper tilting portion. The end of the inner rail protrudes more toward the outer rail than the upper end of the inner rail at the end opposite to the guide direction.

  According to this, when the tilting member is in the first tilt position, the upper tilting portion is closer to the outer rail than the upper tip of the inner rail (specifically, the surface of the upper tip in the outer rail). In addition, the lower tilting portion is located on the opposite side of the outer rail from the upper tip portion of the inner rail (specifically, the surface of the upper tip portion on the outer rail side). For this reason, the upper tilting portion is tilted from the shaft-like rotating member into the ball guide passage, and the lower tilting portion is positioned away from the ball guide passage to the opposite side of the outer rail.

  In such a state, when a game ball is launched into the ball guide passage as a preceding game ball, the preceding game ball passes through the ball guide passage and collides with the upper tilting portion to push the upper tilting portion upward. In this manner, the tilting member is tilted toward the second tilting position, and is guided from the ball guide passage into the game area formed on the board surface of the game board inside the outer rail and the inner rail.

  Thus, after the preceding game ball is guided into the game area, the tilting member tilts to the first tilting position under the weight of the lower tilting portion. For this reason, an upper side tilting part tilts to the outer rail side rather than the upper side front-end | tip part of an inner rail, and a lower side tilting part tilts to the opposite side to an outer rail rather than the upper side front-end | tip part of an inner rail.

  In such a first tilting position of the tilting member, when a player launches a game ball with a thread into the ball guide passage as a subsequent game ball following the preceding game ball for the purpose of cheating, the thread The attached game ball is guided along the ball guide path with the thread attached thereto, and is guided into the game area while pushing up the upper tilting portion. At this time, the tilt member is tilted to the second tilt position.

  When the game ball with thread is guided into the game area as described above, the thread of the game ball with thread is pulled out along the surface on the outer rail side of the inner rail and the surface on the outer rail side of the upper tilting portion. It moves downward along the board surface of the game board within the game area from the tip of the tilting part.

  As a result, the yarn forcibly holds the tilting member at the second tilting position against the weight of the lower tilting portion at the second tilting position of the tilting member.

  Therefore, following the game ball with a thread, when the game ball is sequentially guided into the ball guide passage and moves toward the tilting member side at least along the outer rail side surface of the inner rail, Each of the game balls collides with the end of the lower tilting portion protruding from the inner rail to the outer rail side as described above, and cannot enter the game area. .

  According to the above, even if an illegal act using the game ball with thread is possible because the game ball with thread is guided into the game area, the ball guide is successively followed by the game ball with thread. Of the game balls guided in the aisle, the game ball along the outer rail surface of the inner rail enters the game area due to a collision with the end of the lower tilting portion opposite to the guide direction. The entry is blocked.

  In this way, even if the gaming ball with a thread allows a fraudulent act by the gaming ball with a thread and the game ball wins a prize (for example, wins a start chucker), each subsequent gaming ball thereafter By blocking the game according to, each succeeding game ball cannot be won by the player by an illegal act using the game ball with a thread. As a result, it is impossible to illegally acquire a prize ball by winning each game ball following the game ball with a thread. This means that cheating using a game ball with a thread is minimized.

  According to a second aspect of the pachinko gaming machine of the present invention, in the pachinko gaming machine according to the first aspect, when the tilting member is at the second tilting position, the guide direction of the lower tilting portion. The length of the lower tilting portion is set such that the distance between the end portion in the opposite direction to the corresponding portion of the outer rail is narrower than the outer diameter of the game ball. To do.

  Thereby, not only when the game ball launched as a subsequent game ball in the ball guide passage moves along the surface of the inner rail along the outer rail side, but also when the ball moves along the inner rail side surface of the outer rail Since the interval between the end of the lower tilting portion of the tilting member in the second tilting position in the direction opposite to the guide direction and the corresponding portion of the outer rail with respect to this is narrower than the outer diameter of the game ball, Similarly to the above, the game ball collides with the end of the lower tilting portion in the direction opposite to the guide direction, and cannot enter the game area. As a result, the function and effect described in claim 1 can be further improved.

  With the tilting member of the ball return prevention device positioned at the upper tilting portion on the outer rail side with respect to the upper end of the inner rail, the game ball with thread pushes up the upper tilting portion through the ball guide passage Even if guided into the game area, the thread is pulled by the game ball with the thread moving downward in the game area, and the tilting member protrudes to the outer rail side from the inner rail at the lower tilting portion. Therefore, among the game balls that are subsequently launched into the ball guide passage, at least the game ball that moves along the surface on the outer rail side of the inner rail is the end of the lower tilting portion in the direction opposite to the guide direction. It is possible to prevent entry into the game area by colliding with the part. For this reason, winning for the acquisition of the game ball by the subsequent game ball using the game ball with thread illegally can be prevented.

  In addition, the code | symbol in the bracket | parenthesis of each said means shows a corresponding relationship with the specific means as described in embodiment mentioned later.

As shown in FIG. 2, the guide rail 20 is composed of an inner rail 21 and an outer rail 22, and the inner rail 21 and the outer rail 22 are positioned so as to be located on the inner peripheral side of the outer rail 22. The game board 10 is disposed on the board surface 11 along the outer periphery thereof.

  Here, as shown in FIG. 2, the outer rail 22 protrudes in the longitudinal direction on the board surface 11 of the game board 10 along the outer peripheral portion thereof from the upper right side to the lower left side of the board surface 11 and on the upper left side. The outer rail 22 is extended so as to stand forward from the board surface 11 in the width direction.

  In addition, the inner rail 21 has a predetermined rail interval (interval wider than the outer diameter of the game ball) with respect to the outer rail 22 along the board surface 11 of the game board 10 on the inner side along the outer rail 22 in the longitudinal direction. As shown in the figure, it is arranged in an arc shape that protrudes obliquely downward to the left from the upper left part of the board surface 11 to the central part of the lower edge of the board surface 11, and the inner rail 21 extends in the width direction. Thus, the game board 10 extends forward from the board surface 11.

  Thus, according to the guide rail 20 configured as described above, the outer rail 22 and the inner rail 22 form a game area 11a on the board surface 11 of the game board 10 inside as shown in FIG. . Further, as shown in FIG. 2, the inner rail 21 and the outer rail 22 are arranged so as to be spaced apart from each other as described above, so that a ball guide is provided on the board surface 11 of the game board 10 therebetween. A passage 11b is formed. Accordingly, the ball guide passage 11b has a width corresponding to the predetermined rail interval.

  In the present embodiment, the ball guide passage 11b receives a game ball that is launched between the inner rail 21 and the outer rail 22 from a ball launching device (not shown) by a turning operation of the handle H (see FIG. 1). It plays a role of guiding into the game area 11a. In addition, the said ball | bowl launching device is arrange | positioned in the lower right part of the said frame of the gaming machine main body B. In addition, the handle H is provided as a component part of the ball launcher from the front side at the lower right portion of the front door FD.

Each game nail of the game nail group is driven into the game board 10 in a distributed manner from the board surface 11 side from the left side to the lower side of the center decoration 30 inside the guide rail 20.

  Further, a ball passage 11 c is formed in a part of the game area 11 a between the upper right side portion of the center decoration 30 and the outer rail 22. Thus, when the game ball launched at the maximum firing speed by the ball launching device is guided by the ball guide path 11b, moves along the upper inner peripheral surface of the outer rail 22, and is guided to the ball path 11c. The game ball falls to the lower right of the center decoration 30 after passing through the ball passage 11c.

  In addition, the gaming machine main body B includes an image display 50, and the image display 50 faces the front from the opening provided in the center of the gaming board 10 at the liquid crystal panel 51. Arranged on the back surface of the game board 10, various images are displayed under the control of a display control circuit (not shown).

  Further, the gaming machine main body B includes a start chucker 60a that is a first starter device, an electric tulip 60b that is a second starter device, a through gate 70, a plurality of normal winning ports 80, and an attacker 90 that is a big winning port device. The start chucker 60a, the electric tulip 60b, the through gate 70, the plurality of normal winning holes 80 and the attacker 90 are distributed in the game area 11a on the board surface 11 of the game board 10 as shown in FIG. Are assembled.

  Here, the start chucker 60a is assembled to the board surface 11 of the game board 10 immediately below the center of the center decoration 30, and the start chucker 60a is a big hit lottery based on the winning of a game ball to the start chucker 60a. Create an opportunity to win a lottery.

  The electric tulip 60b is assembled from the board surface 11 side of the game board 10 directly below the start chucker 60a, and the electric tulip 60b is used to open a game ball when the two blade members (not shown) are opened. In the same way as the start chucker 60a, a chance to win a big hit is formed based on the winning of the game ball.

  As shown in FIG. 2, the through gate 70 is assembled to the game board 10 from the board surface 11 side obliquely below and to the right of the lower right corner of the central opening of the game board 10.

  Thus, when the game ball rolls downward along the board surface 11 of the game board 10 through the ball passage 11c and passes through the through gate 70, the passage of the game ball with respect to the through gate 70 is detected, and the electric tulip 60b is moved. A lottery opportunity to open or not is formed.

  The plurality of normal winning ports 80 are assembled to the lower left portion of the board surface 11 of the game board 10 so as to be positioned on the inner peripheral side of the inner rail 21. Thus, when a game ball that rolls downward along the board surface 11 of the game board 10 wins each normal winning slot 80, the winning of the game ball for each normal winning slot 80 is detected, and the lottery as described above is performed. An opportunity to pay out a predetermined number of game balls is formed without giving an opportunity.

  The attacker 90 is assembled to the game board 10 from the board surface 11 side between the start chucker 60 a and the electric tulip 60 b and the through gate 70. As a result of the above jackpot lottery, the attacker 90 repeats the opening and closing operation when it is a jackpot, and turns into a large number of game balls that roll sequentially downward along the board surface 11 of the game board 10 from the ball path 11c. Give them a chance to win.

  Further, as shown in FIG. 2, the gaming machine main body B includes a ball return prevention device 100, and this ball return prevention device 100 is located in the vicinity of the upper end portion 21 a of the inner rail 21 of the game board 10. It is assembled to the board surface 11. As shown in any of FIGS. 2, 3, and 5, the upper tip portion 21 a of the inner rail 21 is a tip portion located on the upper left corner side of the board surface 11 of the game board 10 in the inner rail 21. Say.

  As shown in FIGS. 3 and 4, the ball return prevention device 100 includes a device main body 110 and a tilting member 120.

  The apparatus main body 110 is made of a synthetic resin, and the apparatus main body 110 includes a longitudinal mounting substrate portion 111 and a tilt regulating plate portion 112 as shown in FIGS. 3 and 4.

  As shown in FIG. 3, the mounting substrate portion 111 has a plurality of screws 113 (one screw in FIG. 4) from the board surface 11 side along the game board 10 in the vicinity of the upper end portion 21 a of the inner rail 21. 113 is shown).

  Here, the lower portion in the longitudinal direction of the mounting board portion 111 is fastened by a screw 113 along the board surface 11 of the game board 10 so as to engage with the upper end portion 21a of the inner rail 21 from the right side. The upper part in the longitudinal direction of the mounting board 111 is fastened by screws 113 along the board surface 11 of the game board 10 so as to extend in the extending direction from the lower part in the longitudinal direction to the upper side of the inner rail 21. This is because the mounting board portion 111 is formed at the edge of the inner rail 21 at the upper end portion 21a of the inner rail 21 and along the direction extending obliquely upward to the right in FIG. It means that it is fastened to the board surface 11.

  The tilt regulating plate 112 is for regulating the tilting member 120 in the clockwise direction or the counterclockwise direction shown in FIG. 3 within a predetermined tilt angle range as will be described later. 112 extends from the intermediate portion in the longitudinal direction of the mounting substrate portion 111 toward the front of the game board 10. The predetermined tilt angle range refers to an angle range between a left tilt end and a right tilt end of an upper tilt portion 120a of the tilt member 120 described later.

  As shown in FIG. 3 or FIG. 4, the tilt restricting plate portion 112 has a belt-like curved wall portion 112a and a restricting wall portion 112b. The curved wall portion 112a has an outer wall as shown in FIG. A curved shape that is concave toward the rail 22 side extends forward from the game board 10 from the longitudinal intermediate portion of the mounting substrate portion 111. Thereby, the said curved wall part 112a has faced the outer rail 22 from the right side in the upper end part 112c.

  Here, the curved wall 112a plays a role of regulating the tilt angle of the tilt member 120 in the clockwise direction shown in FIG. In the present embodiment, hereinafter, the upper end portion 112c of the curved wall portion 112a is also referred to as an upper regulating portion 112c.

  The restriction wall 112b extends from the lower intermediate portion in the longitudinal direction of the curved wall 112a toward the outer rail 22, and the restriction wall 112b is formed by extending the outer rail 22 at its extended end. It faces from the right side. Therefore, the regulation wall portion 112b plays a role of regulating the tilt angle of the tilt member 120 in the counterclockwise direction shown in FIG.

  As shown in FIG. 3 or FIG. 4, the tilting member 120 is assembled to the mounting base 111 via its cylindrical rotation shaft 120c (described later). The tilting member 120 is as described below. With the cylindrical rotation shaft 120c as an axis, it is integral with the rotation shaft 120c and can be tilted clockwise or counterclockwise as shown in FIG.

  As shown in FIG. 3 or FIG. 4, the tilting member 120 includes upper and lower side tilting portions 120a and 120b made of a synthetic resin, a cylindrical rotating shaft 120c, and a support pin 120d.

  Both the upper and lower inclined portions 120a and 120b are integrally formed with the cylindrical rotation shaft 120c so as to face the outer rail 22 on each surface on the outer rail 22 side. Here, the upper tilting portion 120a has a rectangular plate shape, and the upper tilting portion 120a integrally extends upward from the cylindrical rotation shaft 120c perpendicular to the axis. On the other hand, the lower tilting portion 120b serves as a weight, and the lower tilting portion 120b integrally extends downward from the cylindrical rotating shaft 120c perpendicular to the axis. Note that the lower tilting portion 120b itself may serve as a weight, or may have a configuration in which a weight is separately incorporated or externally attached.

  In the present embodiment, the lower tilting portion 120b forms a predetermined obtuse angle with respect to the center plane in the thickness direction of the upper tilting portion 120a with respect to the axis of the cylindrical rotation shaft 120c. Thus, it extends integrally from the cylindrical rotation shaft 120c. The lower tilting portion 120b contains a metal member.

  As shown in FIG. 3 or 4, the support pin 120 d is for supporting the tilting member 120 on the longitudinal mounting substrate 111 of the apparatus main body 110 so as to be tiltable. The support pin 120 d is a head 121. The shaft-like neck lower part is coaxially extended from.

  The support pin 120d is fitted to the cylindrical rotation shaft 120c of the tilting member 120 so as to be relatively rotatable from the front of the game board 10 at the lower portion of the shaft neck, and the shaft neck of the support pin 120d. The lower part is fitted to the longitudinal intermediate portion of the longitudinal mounting substrate part 111 at the tip part.

  Thereby, the support pin 120d supports the cylindrical rotation shaft 120c in a freely rotatable manner between the head 121 and the mounting substrate 111. In other words, the tilting member 120 is supported by the support pin 120d around the axis of the support pin 120d so as to tilt clockwise or counterclockwise as shown in FIG. Further, by supporting the tilting member 120 in this way, the lower tilting portion 120b is positioned above the upper tip portion 12a of the inner rail 21 at the lower end portion thereof.

  In the ball return prevention device 100 configured as described above, when the tilting member 120 is at the tilting position (indicated counterclockwise tilting position in the figure) shown by the solid line in FIG. The restriction wall 112b of the portion 112 is engaged from the left side and is at the right tilt end position. At this time, as shown in FIG. 3, the upper tilting portion 120a is dissociated to the left from the upper regulating portion 112c of the curved wall portion 112a and is maintained at the left tilting end (see the solid line in the drawing).

  Here, in this embodiment, when the tilting member 120 is at the current tilting end (left tilting end), the upper tilting part 120a is connected to the upper tip 21a of the inner rail 21 (specifically, the outer rail of the upper tip 21a). The surface is maintained at a position tilted to the outer rail 22 side from the line extending upward from the surface 22 side).

  As a result, the tilting member 120 is collided with the game ball guided from the ball guide passage 11b toward the game area 11a through the upper tilting portion 120a, and tilts in the clockwise direction shown in FIG. In addition, it plays a role of preventing the return of the game ball guided from the ball guide passage 11b into the game area 11a to the ball guide passage 11b.

  For this reason, in this embodiment, when the tilting member 120 is at the current tilting end, the distance between the tip end portion of the upper tilting portion 120a and the corresponding portion of the outer rail 22 with respect to this is along the width direction of the ball guide passage 11b. However, the length of the upper tilting portion 120a is selected to be a predetermined length on the assumption of the predetermined obtuse angle so as to be narrower than the outer diameter of the game ball.

  When the tilt member 120 tilts clockwise from its left tilt end (see the solid line in FIG. 3) and reaches the tilt end (right tilt end) indicated by the two-dot chain line in FIG. The tilting portion 120a is engaged with the upper regulating portion 112c of the curved wall portion 112a from the left side and is maintained at the right tilting end. At this time, the lower tilting portion 120b is disengaged leftward from the regulating wall portion 112b of the tilting regulating plate portion 112 and is maintained at the left tilting end (see the two-dot chain line shown in FIG. 3).

  Here, in this embodiment, when the tilting member 120 reaches the right tilting end, the upper tilting portion 120a moves the upper tip portion 21a of the inner rail 21 (specifically, the surface on the outer rail 22 side of the upper tip portion 21a). ) To the game area 11a side (the side opposite to the outer rail 22) from the extended line from the upper side to the upward line. Thereby, the tilting member 120 prevents the game ball along the inner rail 21 from being guided into the game area 11a in the ball guide passage 11b. For this reason, in this embodiment, when the tilting member 120 is at the right tilting end, it follows the width direction of the ball guide passage 11b at a distance between the lower end of the lower tilting portion 120b and the corresponding portion of the outer rail 22 with respect thereto. The length of the lower tilting portion 120a is selected to be a predetermined length on the premise of the predetermined obtuse angle so that the interval is narrower than the outer diameter of the game ball.

  In the present embodiment configured as described above, in the state where the ball launching device is not firing a game ball, in the ball return prevention device 100, the tilting member 120 has its own weight as the weight of the lower tilting portion 120b. Based on this, as shown by the solid line in FIG. 3, the left tilt end is maintained.

  At this time, the lower tilting portion 120b is engaged with the regulation wall portion 112b of the tilt regulating plate portion 112 from the tip portion and maintained at the right tilting end, and the upper tilting portion 120a is maintained at the left tilting end. (See FIG. 3). In such a state, the lower tilting portion 120b does not protrude from the extension line of the upper end portion 21a of the inner rail 21 to the outer rail 22 side as shown by a solid line in FIG. For this reason, the space | interval between the lower side inclination part 120b and the corresponding | compatible site | part of the outer rail 22 with respect to this is the width | variety of the spherical guide path 11b, ie, the said predetermined rail space | interval.

  On the other hand, as shown by a solid line in FIG. 3, the upper tilting portion 120 a is located on the outer rail 22 beyond the extension line of the upper tip portion 21 a of the inner rail 21 (specifically, the surface of the upper tip portion 21 a on the outer rail 22 side). Protrudes to the side. For this reason, the space | interval between the front-end | tip part of the upper side inclination part 120a and the corresponding | compatible site | part of the outer rail 22 with respect to this is narrower than the outer diameter of a game ball as mentioned above.

  In such a state, a game ball (hereinafter also referred to as a predecessor game ball) is fed from the ball tray DS to the ball launcher side through a ball feeder (not shown) and is moved into the ball guide path 11b by the ball launcher. When it is launched, the preceding game ball is guided toward the game area 11a by the ball guide passage 11b.

  In such a guiding process, as described above, the distance between the tip of the upper tilting portion 120a and the corresponding portion of the outer rail 22 is narrower than the outer diameter of the game ball as described above. The preceding game ball collides with the upper tilting portion 120a of the tilting member 120 from below. At this time, as described above, the lower tilting portion 120b protrudes from the extension line of the upper tip portion 21a of the inner rail 21 (specifically, the surface of the upper tip portion 21a on the outer rail 22 side) to the outer rail 22 side. Therefore, the preceding game ball is not buffered by the lower tilting portion 120b prior to the collision with the upper tilting portion 120a.

  Thus, when the tilting member 120 receives the force due to the collision of the preceding game ball at the upper tilting portion 120a and tilts in the clockwise direction shown in FIG. 3 about the support pin 120d, the tilting member 120 is It reaches the right tilting end and engages with the upper regulating portion 112c of the curved wall portion 112a at the upper tilting portion 120a. Accordingly, the lower tilting portion 120b reaches the tilting end (left tilting end) indicated by a two-dot chain line in FIG. 3, but the preceding game ball has already collided with the upper tilting portion 120a as described above. Therefore, there is no particular problem.

  Accordingly, as the tilting member 120 is rotated in the clockwise direction as described above, the distance between the tip end portion of the upper tilting portion 120a and the corresponding portion of the outer rail 22 with respect thereto is wider than the outer diameter of the game ball. Thus, the preceding game ball is guided into the game area 11a through the space between the tip of the upper tilting portion 120a and the corresponding portion of the outer rail 22 corresponding thereto.

  Thereafter, the tilting member 120 tilts counterclockwise as shown in FIG. 3 under its own weight as the weight of the lower tilting portion 120b. Therefore, the upper tilting part 120b reaches its left tilting end, and the lower tilting part 120b reaches its right tilting end, and engages with the regulation wall part 112b of the tilt regulation plate part 112 from its tip part. .

  In such a stage, when a subsequent game ball (hereinafter also referred to as a subsequent game ball) is fired toward the ball guide path 11b by the ball launching device, the subsequent game ball is shown in FIG. It will be guided by the ball guide path 11b toward the tilting member 120 at the tilting position of the chain line.

  Here, as described above, when the tilting member 120 is maintained at the right tilting end, the distance between the lower end of the lower tilting portion 120b and the corresponding portion of the outer rail 22 relative to the lower tilting portion 120b is larger than the outer diameter of the game ball. It is narrower.

  Therefore, even if the subsequent game ball is guided toward the tilting member 120 by the ball guide passage 11b as described above, the subsequent game ball is buffered by the lower end portion of the lower tilting portion 120b and along the ball guide passage 11b. In reverse, the game board 10 is discharged from an out port (not shown).

  By the way, if the above-mentioned subsequent game ball is a game ball stored in the ball tray DS as a game ball with a thread, the game ball with a thread is accompanied by a thread t (refer to FIG. 5). It is sent out from the tray DS to the ball launcher side through a ball feeder (not shown). In addition, the game ball with a thread is configured by fixing the base end portion of the thread t to the outer peripheral surface of the game ball. Further, it is assumed that the thread t is gripped in the tray DS by the player's hand at the tip.

  Thus, when the game ball with a thread sent out as described above is launched toward the ball guide path 11b by the ball launching device, the game ball with a thread is accompanied by a thread t (see FIG. 5). Then, it is guided toward the tilting member 120 by the ball guide passage 11b.

  Here, in the ball return prevention device 100, as described above, the game ball with a thread tilts the tilting member 120 to the right tilting end (see the two-dot chain line shown in FIG. 3) and then plays the game from the ball guide passage 11b. Guided into region 11a.

  Then, the thread-equipped game ball guided into the game area 11a in this way moves downward along the board surface 11 of the game board 10 while colliding with the game nail in the game area 11a while accompanying the thread t. It will be.

  Along with the movement of the game ball with the thread, the thread t is pulled by the game ball with the thread in the tilted state toward the right tilt end of the tilting member 120, and in the game area 11a together with the game ball with the thread. It will be drawn downward. In such a process, the thread t is drawn along the surface on the outer rail 22 side of the inner rail 21 and the surface on the outer rail 22 side of the upper tilting portion 120a of the ball return prevention device 100, and the tip of the upper tilting portion 120a. It moves downward along the board surface 11 of the game board 10 within the game area 11a.

  As a result, the thread t forces the tilting member 120 to the right tilting end at the right tilting end of the tilting member 120 of the ball return prevention device 100 against its own weight as the weight of the lower tilting portion 120b. Will be held.

  For this reason, following the game ball with thread, the game balls are sequentially guided into the ball guide passage 11b by the ball launching device, and as illustrated in FIG. When moving toward the tilting member 120 side along the surface, each game ball is on the outer rail 22 side rather than the inner rail 21 (specifically, the surface on the outer rail 22 side of the inner rail 21) as described above. It collides with the lower end part of the lower tilting part 120b protruding to the point and cannot enter the game area 11a.

  Further, even when each game ball moves toward the tilting member 120 side along the inner rail 21 side surface of the outer rail 22 instead of the surface of the inner rail 21 on the outer rail 22 side, As described above, since the interval between the lower end portion of the lower tilting portion 120b of the tilting member 120 at the right tilting end and the corresponding portion of the outer rail 22 with respect to this is smaller than the outer diameter of the game ball, Similarly to the above, it cannot collide with the lower end portion of the lower tilting portion 120b and enter the game area 11a.

  According to the above, in this embodiment, even if an illegal act using the game ball with thread is possible by guiding the game ball with thread into the game area 11a, All the game balls guided successively into the ball guide passage 11b are all prevented from entering the game area 11a due to a collision with the lower tilting portion 120b of the tilting member 120.

  Along with this, all games in the game area 11a are blocked, including games advantageous to the player such as winning an attacker 90 in the game area 11a using each of these succeeding game balls. .

  In this way, even if the gaming ball with a thread allows a fraudulent act by the gaming ball with a thread and the game ball wins a prize (for example, wins a start chucker), each subsequent gaming ball thereafter By blocking all the games according to, each succeeding game ball cannot be awarded to the attacker 90 or the like by an illegal act using the game ball with a thread by the player. As a result, it is not possible to illegally acquire a prize ball by causing the attacker 90 to win each game ball following the game ball with a thread. This means that cheating using a game ball with a thread is minimized.
