  An object of the present invention is to obtain a gaming machine that can prevent an illegal act of acquiring a game ball using a game ball with a thread.

  According to a first aspect of the present invention, there is provided a gaming machine that rotates between a detection means for detecting a game ball flowing through a ball passage, and a blocking position for blocking the ball passage and an opening position for opening the ball passage downstream of the detection means. It is provided so as to be movable, and when it contacts with the game ball that has passed through the detection means, it rotates to the open position and flows to the downstream side, and after the game ball has passed, it rotates to the blocking position. A backflow restricting member that blocks the ball passage and restricts the movement of the game ball that has passed through the detecting means to the detecting means.

  According to the above configuration, when an illegal act is performed using a game ball with a thread, the game ball with a thread passing through the detecting means or passing through the thread is blocked at the blocking position. Contact with. Then, when the backflow restricting member rotates to the open position to open the ball passage, the game ball with the thread flows downstream from the backflow restricting member. Subsequently, the backflow restricting member rotates to the blocking position and blocks the ball passage again. Thereby, since the movement of the game ball that has passed through the detection means to the detection means is restricted, it is possible to prevent the game ball with a thread from passing through the detection means a plurality of times, and to prevent cheating.

  In the gaming machine according to claim 2 of the present invention, the backflow restricting member is a plate member that blocks the ball passage, a support means that rotatably supports the plate member, and the plate member is rotated to the blocking position. And a balance section for applying a rotational force.

  According to the above configuration, when the game ball comes into contact with the plate material supported by the support means and in the blocking position, the push-down force due to the weight of the game ball is greater in the plate material than the rotational force applied by the balance unit. The plate material is rotated to the open position, the ball passage is opened, and the game ball flows downstream. On the other hand, after the game ball passes through the plate material, only the turning force by the balance portion is applied to the plate material, so that the plate material rotates to return to the blocking position and blocks the ball passage. In this way, the spherical passage can be automatically opened and closed by the backflow restricting member.

  In the gaming machine according to claim 3 of the present invention, the backflow restricting member is provided with a biasing means for biasing the plate material to the blocking position.

  According to the above configuration, after the game ball passes through the plate material, the plate material is urged by the urging means and rotates to the blocking position. Thereby, compared with the structure which does not provide the urging | biasing means, a board | plate material can be returned to the interruption | blocking position in a short time.

  A gaming machine according to claim 4 of the present invention notifies an unauthorized state when an opening time detecting means for detecting an opening time of the backflow regulating member and an opening time detected by the opening time detecting means exceeds a set time. And an informing means.

  According to the above configuration, when a member different from the game ball with a thread is used and the backflow restricting member is rotated and held in the open position, the open time detecting means is in the open state. Is detected (opening time). Then, when the opening time detected by the opening time detection means exceeds the set time, the notification means determines that the gaming machine is in an unauthorized state and notifies that the gaming machine is in an unauthorized state by flashing light or a warning sound. To do. Thus, even if a member different from the game ball with a thread is used and the backflow restricting member is held in the open position, the illegal state can be suppressed.

  The gaming machine according to claim 5 of the present invention is provided with a movement restricting member that restricts the backflow restricting member from moving toward the detecting means from the blocking position.

  According to the above configuration, the movement restricting member restricts the backflow restricting member from moving to the detecting means side from the blocking position, so that the backflow restricting member can be prevented from contacting the detecting means.

  Since the present invention has the above configuration, it is possible to prevent an illegal act of acquiring a game ball using a game ball with a thread attached thereto.

(Game board configuration)
As shown in FIG. 2, the game board 22 has a resin sheet-like cell attached to a plywood board serving as a substrate, and the surface of the cell is a board surface. An outer rail 72 and an inner rail 74 are attached. In the circular area surrounded by the outer rail 72 and the inner rail 74, the game ball PB launched from the launching device (not shown) can be moved by its own weight fall, and this area plays a game. It is designated as a game area F.

  Nails (not shown) and windmills 76 are scattered and driven into the game area F of the game board 22. In addition, a center accessory 80 is arranged at substantially the center in the game area F. The center accessory 80 includes an LCD display unit 82 that displays images of various effects and the like.

  In the LCD display unit 82, for example, the symbol variation pattern effect is such that when the three symbol sequences fluctuate independently and finally the three symbol sequences stop at the same symbol, the winning of the special symbol lottery is notified. Is executed. Of the three columns, two columns stop at the same symbol first (temporary stop) and the remaining one column is changing, or among the three columns, the left and right two columns stop at the same symbol first. (Temporary stop) and the case where the remaining central row is changing is called “reach”.

  A stage 80 </ b> S is formed on the lower side of the center accessory 80. A game ball PB received by bouncing back with a nail or the like, or a game ball PB received guided by a warp path (not shown) is sent to the stage 80S.

The ball guide panel is attached so that a plurality of ball passages correspond to the winning holes (special symbol starting winning holes 86A, 86B, side winning holes 102A, 102B, 102C) concentrated at the lower part of the center bonus 80. It has been.

(Main part configuration)
Next, the configuration of the backflow restricting plate 100 and the ball passage member 108 as an example of a backflow restricting member that restricts the backflow of the game ball PB will be described.

  FIG. 3A shows a side winning opening 102A as an example of a plurality of winning openings. A ball passage member 108 is provided behind the side winning opening 102A to guide the game balls PB won in the side winning opening 102A to a collecting unit (not shown). The ball passage member 108 constitutes a part of the above-described ball guide panel (not shown), and includes a ball passage 108A extending from the side winning opening 102A in the lower right direction and a ball passage 108A. And a ball passage 108B extending downward from the lower end of the lens. A ball detection sensor 110 as an example of a detection unit that detects the game ball PB is provided in the middle of the ball passage 108B.

  As shown in FIG. 4, the ball detection sensor 110 is a proximity sensor that detects the presence or absence of a metal game ball PB by a change in impedance of a detection coil of a high-frequency oscillation circuit, and is a thin plate-like rectangular parallelepiped shape that is circular. A passage hole 112A is formed. The passage hole 112A is a detection region for detecting the game ball PB, and a detection unit 112B having a detection coil is provided in this detection region (periphery of the passage hole 112A).

  In addition, the sphere detection sensor 110 is provided with a signal generation unit 112C including a high-frequency oscillation circuit that receives the signal from the detection unit 112B and generates an output signal. Here, when driving power is supplied to the ball detection sensor 110, an H signal (3.3V or 5.0V) is detected as a detection signal in a state where the game ball PB does not pass through the passage hole 112A (normal state). Output. Conversely, when the game ball PB passes through the passage hole 112A, an L signal (no signal) is generated.

  Thus, when the H signal is detected when the game ball PB is not detected and the L signal is detected, the H signal is maintained even if, for example, a part of the external radio wave reaches the detection area of the ball detection sensor 110. Will be. That is, external radio waves have the ability to convert the output of the L signal (no signal state) into an H signal, but not the ability to convert the H signal into an L signal. And the signal generation part 112C of the ball | bowl detection sensor 110 is connected to the control part 90 which is an example of an open time detection means while controlling the operation | movement of each part of the pachinko machine 10 (refer FIG. 1).

  When the game ball PB completely passes through the ball detection sensor 110, that is, when the H signal changes from the H signal to the L signal, the control unit 90 pays out a prize ball from the ball payout means (not shown). It is the composition which makes it. Further, the control unit 90 is connected to the speaker 50 and the triple indicator lamp 64 (see FIG. 1), and selects the sound effect or warning sound output from the speaker 50 and the lighting state of the triple indicator lamp 64. Changes (flashing, constant lighting, etc.) are made. In addition, operation | movement of the speaker 50 and the triple indicator lamp 64 by the control part 90 is demonstrated in 3rd Embodiment.

  On the other hand, as shown in FIG. 3A, a backflow restricting plate 100 as an example of a backflow restricting member is provided below the ball detection sensor 110 in the ball passage 108B.

  The backflow restricting plate 100 extends in the direction of the arrow -X from a columnar rotating shaft 100C as an example of a support means arranged with the illustrated depth direction (arrow Y direction) as an axial direction, and a side surface of the rotating shaft 100C. A plate-like contact portion 100A as an example of a plate material and a plate-like balance portion 100B extending in the arrow + X direction from the side surface of the rotary shaft 100C opposite to the contact portion 100A. .

  The contact portion 100A is arranged on the side of the ball passage 108B so that the game ball PB comes into contact therewith. The upper surface 100D of the contact portion 100A is arranged so that the in-plane direction is orthogonal to the flow-down direction of the game ball PB in the initial state where the backflow restricting plate 100 is not rotated, and the ball passage 108B is blocked at this position. (The passage of the game ball PB is blocked). In the following description, the position of the backflow restricting plate 100 in the initial state where the backflow restricting plate 100 is not rotated is defined as a blocking position, and the backflow restricting plate 100 in a state where the game ball PB passes through the backflow restricting plate 100. Is the open position. Further, an up-down direction orthogonal to the arrow X direction and the Y direction is defined as an arrow Z direction.

  The axial direction of the rotating shaft 100C coincides with the arrow Y direction, and the longitudinal direction (arrow X direction) of the contact portion 100A and the balance portion 100B is orthogonal to the arrow Y direction. In the arrow X direction, the length L1 from the axis center O of the rotation shaft 100C to the end portion (left end portion in the drawing) of the contact portion 100A is the end portion of the balance portion 100B (shown in the drawing) from the axis center O of the rotation shaft 100C. To the right end portion) is longer than the length L2.

  Further, the rotating shaft 100C is supported by an arrow + R direction (clockwise direction shown) or an arrow −R direction (counterclockwise shown) by a bracket 103 as an example of a support means provided inside the pachinko machine 10 (see FIG. 1). It is supported so that it can rotate in the rotation direction. The arrow + R and -R directions are the moving directions in the XZ plane, the arrow + R direction is the direction in which the backflow restricting plate 100 approaches the ball detection sensor 110, and the arrow -R direction is the backflow restricting plate 100. Is in a direction away from the sphere detection sensor 110.

  On the other hand, a weight member 101 is attached to the lower surface of the balance portion 100B, and a turning force (force toward the blocking position) is applied to the backflow regulating plate 100. In this embodiment, the weight member 101 is attached as a separate member in order to enable adjustment of the weight of the balance portion 100B. However, the balance portion 100B and the weight member 101 may be integrated. When integrated, the thickness of the balance portion 100B may be thicker than the thickness of the contact portion 100A. For this reason, the weight member 101 shall be contained in the balance part 100B.

  Here, with the axis center O as a boundary, the weight of the contact portion 100A including the rotation shaft 100C is Wt1, the weight of the balance portion 100B including the rotation shaft 100C is Wt2, and the weight of the weight member 101 is Wt3, and the game ball PB Each weight is set so as to meet an inequality of Wt1 ≦ (Wt2 + Wt3) <(Wt1 + Wt4) (hereinafter referred to as inequality A).

  The setting of the weights Wt1, Wt2, Wt3, Wt4 using the inequality A is an example of setting the weight of each member, and the moment including the length L1 of the contact part 100A and the length L2 of the balance part 100B is also described. Set in consideration. By setting the weight of each member in this manner, the backflow restricting plate 100 rotates in the arrow −R direction or the arrow + R direction without using a rotation driving means such as a motor due to contact or non-contact with the game ball PB. It is possible to move.

  Here, in the state where the backflow restricting plate 100 is disposed at the blocking position (initial position), the distance between the lower surface 112D of the ball detection sensor 110 and the upper surface 100D of the backflow restricting plate 100 is Δd1, and the diameter of the game ball PB is In this embodiment, Δd1 is set as d so that 0 <Δd1 <d. This prevents the game ball PB with the thread 106 from moving up and down the ball detection sensor 110 in the state where the backflow restricting plate 100 is held at the installation position.

  A stopper member 116 as an example of a movement restricting member that restricts the upward movement of the contact portion 100A is provided above the end portion (left end portion in the drawing) of the contact portion 100A of the backflow restricting plate 100. The stopper member 116 is a plate material. The lower surface of the stopper member 116 is in contact with the upper surface 100D of the contact portion 100A, so that the backflow regulating plate 100 is held at the blocking position (initial position).

  As shown in FIG. 3 (B), vertical holes 109A and 109B of such a size that the contact portion 100A of the backflow restricting plate 100 can be inserted and moved are formed in the pair of side walls 108C and 108D of the ball passage member 108. Has been. The width W1 and W2 are set so that W1 <W2 <d, where W1 is the width of the contact portion 100A in the arrow Y direction and W2 is the width of the vertical holes 109A and 109B. The holes 109A and 109B are inserted. Since the width W2 of the vertical holes 109A and 109B is smaller than the diameter d of the game ball PB, the game ball PB does not flow out of the vertical hole 109A or the vertical hole 109B. Further, the width W3 of the ball passage 108B in the width direction of the contact portion 100A is narrower than twice (2d) the diameter of the game ball PB, and the game is played downstream from the gap between the contact portion 100A and the ball passage 108B. It is set so that the sphere PB does not fall.

  Next, the operation of the first embodiment will be described.

  As shown in FIG. 5 (A), when an illegal act in which the game ball PB with the thread 106 flows down from the side winning opening 102A through the ball path 108A through the ball path 108B, the game ball PB passes the ball detection sensor 110. The lower part of the inside game ball PB comes into contact with the contact portion 100A of the backflow restricting plate 100 blocking the ball passage 108B. At this time, since the weight of the game ball PB acts on the contact portion 100A, the contact portion 100A (including the game ball PB) becomes heavier than the balance portion 100B, that is, a pressing force acts on the contact portion 100A. The reverse flow restricting plate 100 is rotated to the open position (arrow -R direction) to open the ball passage 108B. 5A and 5B, the bracket 103 is not shown.

  Then, the game ball PB with the thread 106 passes through the backflow restriction plate 100 when the backflow restriction plate 100 opens the ball passage 108B (flows downstream from the backflow restriction plate 100). Since the game ball PB with the thread 106 flows down in the ball passage 108B by its own weight, the backflow restricting plate 100 does not stop during the rotation to the open position, and the game ball PB with the thread 106 It will be located downstream of the reverse flow regulating plate 100 in the passage 108B.

  Subsequently, as shown in FIG. 5B, the backflow restricting plate 100 is such that the weight of the game ball PB with the thread 106 does not act, and the total weight of the balance portion 100B and the weight member 101 is the contact portion 100A. If it is heavier than the weight, it automatically rotates in the direction of the arrow + R toward the blocking position. And the backflow control board 100 is hold | maintained at the interruption | blocking position because the edge part of the contact part 100A contacts the stopper member 116, and interrupts | blocks the ball path 108B again. As described above, the stopper member 116 restricts the backflow restricting plate 100 from moving to the sphere detection sensor 110 side from the blocking position, and thus prevents the backflow restricting plate 100 from contacting the sphere detecting sensor 110. it can.

  Subsequently, when the fraudster pulls the thread 106 upward, the game ball PB with the thread 106 tends to move upward in the ball passage 108B. However, since the backflow restricting plate 100 blocks the ball passage 108B, the game ball PB with the thread 106 comes into contact with the lower surface of the backflow restricting plate 100 (contact portion 100A) and the movement is restricted, and the ball detection sensor 110 Will not pass through. In this way, the movement of the back-flowing game ball PB from the position downstream from the blocking position toward the upstream is restricted to the ball detection sensor 110, so that the game ball PB with the thread 106 moves the ball detection sensor 110. Passing multiple times is prevented, and cheating can be prevented.

  Next, a gaming machine according to the second embodiment of the present invention will be described. Note that the same reference numerals as those in the first embodiment are given to the members that are basically the same as those in the first embodiment described above, and the description thereof is omitted. Moreover, in each figure, description of the arrows X, Y, and Z is abbreviate | omitted.

  6A and 6B show a pachinko machine 130 as an example of the gaming machine of the second embodiment. The pachinko machine 130 has a triple indicator lamp 64 and a speaker 50 (see FIG. 1), like the pachinko machine 10 of the first embodiment. The pachinko machine 130 has a ball passage member 108 through which the game ball PB flows, and a backflow restricting plate 132 as an example of a backflow restricting member and a plate material is provided below the ball detection sensor 110 in the ball passage 108B. Is provided.

  The backflow restricting plate 132 includes a cylindrical shaft main body 132C disposed with the illustrated depth direction (arrow Y direction) as an axial direction, and a rotating shaft as an example of a support unit that protrudes further outward from both end faces of the shaft main body 132C. 132E, a plate-like contact portion 132A as an example of a plate member extending from the side surface of the shaft main body 132C in the arrow -X direction, and a side surface opposite to the contact portion 132A in the shaft main body 132C from the side surface extending in the arrow + X direction. And a plate-like balance portion 132B provided.

  The contact portion 132A is arranged on the side of the ball passage 108B so that the game ball PB comes into contact therewith. The upper surface 132D of the contact portion 132A is arranged so that the in-plane direction is orthogonal to the flow-down direction of the game ball PB in the initial state where the backflow restricting plate 132 is not rotating, and the ball passage 108B is blocked at this position. (The passage of the game ball PB is blocked). In the following description, the position of the backflow restricting plate 132 in the initial state where the backflow restricting plate 132 is not rotated is defined as a blocking position, and the backflow restricting plate 132 in a state where the game ball PB passes through the backflow restricting plate 132. Is the open position.

  The longitudinal direction of the contact portion 132A and the balance portion 132B is orthogonal to the axial direction of the rotation shaft 132E. The length L1 from the axial center O of the rotating shaft 132E to the end portion (left end portion in the drawing) of the contact portion 132A is from the axial center O of the rotating shaft 132E to the end portion (right end portion in the drawing) of the balance portion 132B. Is longer than the length L2.

  On the other hand, a support member 134 as an example of a support means is erected on the outside of the ball passage member 108 and in the vicinity of the ball detection sensor 110. The support member 134 includes a flat plate-like main body portion 134A disposed in parallel with the side wall 108D of the ball passage member 108, and two upper portions extending upward from both end portions in the depth direction on the upper surface of the main body portion 134A. And a support portion 134B.

  Each of the two support portions 134B is formed with a through hole 134C penetrating in the depth direction. The inner diameter of the through hole 134C is slightly larger than the outer diameter of the rotating shaft 132E, and the rotating shaft 132E of the backflow restricting plate 132 is inserted into the through hole 134C. Thus, the backflow restricting plate 132 is provided so as to be rotatable in the arrow + R direction (clockwise direction in the drawing) or in the arrow -R direction (counterclockwise direction in the drawing). Note that a bearing may be fitted into the through-hole 134C to support the rotating shaft 132E in a rotatable manner.

  A weight member 138 is attached to the lower surface of the balance portion 132B so as to apply turning force (force toward the blocking position) to the backflow restricting plate 132. In the present embodiment, the weight member 138 is attached as a separate member in order to adjust the weight of the balance portion 132B. However, the balance portion 132B and the weight member 138 may be integrated. When integrated, the thickness of the balance portion 132B may be thicker than the thickness of the contact portion 132A. For this reason, the weight member 138 shall be contained in the balance part 132B.

  Further, one end of a torsion spring 136 as an example of an urging means for urging the reverse flow restricting plate 132 in a direction to block the ball passage 108B is attached near the center of the lower surface of the contact portion 132A of the reverse flow restricting plate 132. . The other end of the torsion spring 136 is attached to the side surface (side surface facing the side wall 108D) of the main body 134A of the support member 134. As a result, when the backflow restricting plate 132 rotates in the direction of the arrow −R from the blocking position, the urging force (rotation force) for rotating the backflow restricting plate 132 in the direction of the arrow + R is applied by the torsion spring 136. ing.

  Here, with the axis center O as a boundary, the weight of the contact portion 132A including the rotation shaft 132E is Wt5, the weight of the balance portion 132B including the rotation shaft 132E is Wt6, and the weight member 138 is Wt7, and the game ball PB Each weight is set so as to meet an inequality of Wt5 ≦ (Wt6 + Wt7) <(Wt4 + Wt5) (hereinafter referred to as inequality B).

  The setting of the weights Wt4, Wt5, Wt6, Wt7 using the inequality B is an example of the setting of the weight of each member. The moment including the length L1 of the contact portion 132A and the length L2 of the balance portion 132B, And the biasing force by the torsion spring 136 is also set. By setting the weight of each member in this way, the backflow restricting plate 132 can be rotated in the arrow + R direction or the arrow -R direction without using a rotation driving means such as a motor.

  Here, in the state where the backflow restricting plate 132 is disposed at the blocking position (initial position), the distance between the lower surface 112D of the ball detection sensor 110 and the upper surface 132D of the backflow restricting plate 132 is Δd1, and the diameter of the game ball PB is In this embodiment, Δd1 is set as d so that 0 <Δd1 <d. This prevents the game ball PB with the thread 106 from moving up and down the ball detection sensor 110 in the state where the backflow restricting plate 132 is held at the blocking position.

  Further, a stopper member 116 is provided above the end portion (left end portion in the drawing) of the contact portion 132A of the backflow restricting plate 132. The stopper member 116 is configured to hold the backflow restricting plate 132 in the blocking position (initial position) by having the lower surface in contact with the upper surface 132D of the contact portion 132A.

  As shown in FIG. 6B, the width W1 and W2 are set so that W1 <W2 <d, where W1 is the width of the contact portion 132A and W2 is the width of the vertical holes 109A and 109B. 132A is inserted through the vertical holes 109A and 109B. Since the width W2 of the vertical holes 109A and 109B is smaller than the diameter d of the game ball PB, the game ball PB does not flow out of the vertical hole 109A or the vertical hole 109B.

  Next, the operation of the second embodiment will be described.

  As shown in FIG. 7A, when an illegal act in which the game ball PB with the thread 106 flows down from the side winning opening 102A through the ball passage 108A and through the ball passage 108B is passed, it passes through the ball detection sensor 110. The lower part of the inside game ball PB comes into contact with the contact part 132A of the backflow restricting plate 132 blocking the ball passage 108B. At this time, since the weight of the game ball PB acts on the contact portion 132A, the contact portion 132A (including the game ball PB) is heavier than the balance portion 132B, and the contact portion 132A is subjected to the urging force of the torsion spring 136. In opposition, the backflow restricting plate 132 rotates to the open position (arrow -R direction) to open the ball passage 108B.

  The game ball PB with the thread 106 passes through the backflow restriction plate 132 by the backflow restriction plate 132 opening the ball passage 108B (flows downstream from the backflow restriction plate 132). Since the game ball PB with the thread 106 flows down in the ball passage 108B by its own weight, the backflow restricting plate 132 does not stop during the rotation to the open position, and the game ball PB with the thread 106 It will be located downstream of the backflow restricting plate 132 in the passage 108B.

  Subsequently, as shown in FIG. 7B, the weight of the game ball PB with the thread 106 does not act on the backflow restricting plate 132, and the total weight of the balance portion 132B and the weight member 138 is the weight of the contact portion 132A. Since it is heavier than that and the urging force of the torsion spring 136 is applied, it automatically rotates in the arrow + R direction. And the backflow control board 132 is hold | maintained in the interruption | blocking position because the edge part of the contact part 132A contacts the stopper member 116, and interrupts | blocks the ball path 108B again. In this manner, the stopper member 116 restricts the backflow restricting plate 132 from moving to the sphere detection sensor 110 side from the set position, so that the backflow restricting plate 132 is prevented from contacting the sphere detecting sensor 110. it can.

  Subsequently, when the fraudster pulls the thread 106 upward, the game ball PB with the thread 106 tends to move upward in the ball passage 108B. However, since the backflow restricting plate 132 blocks the ball passage 108B, the game ball PB with the thread 106 comes into contact with the lower surface of the backflow restricting plate 132 (contact portion 132A) and the movement is restricted, and the ball detection sensor 110 Will not pass through. In this way, the movement of the back-flowing game ball PB from the position downstream from the blocking position toward the upstream is restricted to the ball detection sensor 110, so that the game ball PB with the thread 106 moves the ball detection sensor 110. Passing multiple times is prevented, and cheating can be prevented.

  After the game ball PB with the thread 106 passes through the backflow restricting plate 132, the backflow restricting plate 132 is urged by the torsion spring 136 and rotates to the original position where the ball passage 108B is blocked. Compared to the configuration in which no is provided, the backflow restricting plate 132 can be returned to the original position in a short time.

  Next, a gaming machine according to a third embodiment of the present invention will be described. Note that the same reference numerals as those in the first and second embodiments are given to the same members as those in the first and second embodiments described above, and the description thereof is omitted. Moreover, in each figure, description of the arrows X, Y, and Z is abbreviate | omitted.

  8A and 8B show a pachinko machine 140 as an example of the gaming machine of the third embodiment. The pachinko machine 140 has the triple indicator lamp 64 and the speaker 50 (see FIG. 1), similarly to the pachinko machine 10 of the first embodiment. The pachinko machine 140 has a ball passage member 152 through which the game ball PB flows.

  The ball passage member 152 constitutes a part of the above-described ball guide panel (not shown), and includes a ball passage 152A extending from the side winning opening 102A in the lower right direction and a ball passage 152A. And a ball passage 152B extending downward from the lower end of the ball. A ball detection sensor 110 that detects the game ball PB is provided in the middle of the ball passage 152B. Further, a backflow restricting plate 142 as an example of a backflow restricting member and a plate material is provided below the ball detection sensor 110 in the ball passage 152B.

  As shown in FIG. 8B, longitudinal holes 154A and 154B having a size that allows the contact portion 142A of the backflow restricting plate 142 to be inserted and moved are formed in the pair of side walls 152C and 152D of the ball passage member 152. Has been. The widths W1 and W2 are set such that W1 <W2 <d, where W1 is the width of the contact portion 142A in the arrow Y direction and W2 is the width of the vertical holes 154A and 154B. The holes 154A and 154B are inserted.

  Since the width W2 of the vertical holes 154A and 154B is smaller than the diameter d of the game ball PB, the game ball PB does not flow out from the vertical hole 154A or the vertical hole 154B. Further, the width of the ball passage 152B in the width direction of the contact portion 142A is W3 from the ball passage 152A side to the vicinity of the lower side of the backflow restricting plate 142 as in the first and second embodiments (see FIG. 3B). This is narrower than twice the diameter (2d) of the game ball PB, and is set so that the game ball PB does not fall downstream from the gap between the contact portion 142A and the ball passage 152B.

  Here, at a position further downstream from the backflow restricting plate 142, the width of the ball passage 152B in the width direction of the contact portion 142A is widened to W4 (> W3) as shown, and the diameter of the game ball PB is increased. It is wider than twice (2d). This is because when the backflow restricting plate 142 moves downward, the ball passage 152B cannot be completely opened, and thus the ball passage is widened so that the game ball PB is not blocked below the ball passage 152B.

  On the other hand, the backflow restricting plate 142 is a columnar rotating shaft 142C as an example of a supporting means arranged with the illustrated depth direction as an axial direction, and a plate material extending in the arrow -X direction from the side surface of the rotating shaft 142C. The plate-shaped contact part 142A as an example and the plate-shaped balance part 142B extended in the arrow + X direction from the side surface on the opposite side to the contact part 142A in the rotating shaft 142C are comprised.

  The contact portion 142A is arranged on the side of the ball passage 152B so that the game ball PB comes into contact therewith. The upper surface 142D of the contact portion 142A is arranged so that the in-plane direction is orthogonal to the flow-down direction of the game ball PB in the initial state where the backflow restricting plate 142 is not rotating, and the ball passage 152B is blocked at this position. (The passage of the game ball PB is blocked). In the following description, the position of the backflow restricting plate 142 in the initial state where the backflow restricting plate 142 is not rotated is defined as a blocking position, and the backflow restricting plate 142 in a state where the game ball PB passes through the backflow restricting plate 142. Is the open position.

  As shown in FIG. 8A, the longitudinal direction of the contact portion 142A and the balance portion 142B is orthogonal to the axial direction of the rotating shaft 142C. The length L3 from the axial center O of the rotating shaft 142C to the end portion (left end portion in the drawing) of the contact portion 142A is from the axial center O of the rotating shaft 142C to the end portion (right end portion in the drawing) of the balance portion 142B. Is longer than the length L4.

  On the other hand, a support member 144 as an example of a support unit is erected in the vicinity of the ball detection sensor 110 outside the ball passage member 152. The support member 144 includes a flat plate-like main body portion 144A disposed in parallel with the side wall 152D of the spherical passage member 152, and two extending from the both end portions in the depth direction on the upper surface of the main body portion 144A. And a support portion 144B.

  Each of the two support portions 144B is formed with a through hole 144C penetrating in the depth direction. The inner diameter of the through hole 144C is slightly larger than the outer diameter of the rotating shaft 142C, and the rotating shaft 142C of the backflow restricting plate 142 is inserted into the through hole 144C. Thereby, the backflow restricting plate 142 is provided so as to be rotatable in an arrow + R direction (clockwise direction in the drawing) or an arrow −R direction (counterclockwise direction in the drawing). Note that a bearing may be fitted into the through-hole 144C so that the rotating shaft 142C is rotatably supported.

  A weight member 146 is attached to the lower surface of the balance portion 142B so as to apply turning force (force toward the blocking position) to the backflow restricting plate 142. In this embodiment, the weight member 146 is attached as a separate member in order to enable adjustment of the weight of the balance portion 142B. However, the balance portion 142B and the weight member 146 may be integrated. When integrated, the thickness of the balance portion 142B may be thicker than the thickness of the contact portion 142A. For this reason, the weight member 146 shall be contained in the balance part 142B.

  Further, one end of a torsion spring 136 as an example of an urging means for urging the reverse flow restricting plate 142 in a direction to block the ball passage 152B is attached near the center of the lower surface of the contact portion 142A of the reverse flow restricting plate 142. . The other end of the torsion spring 136 is attached to the side surface (side surface facing the side wall 152D) of the main body portion 144A of the support member 144. As a result, when the backflow restricting plate 142 is rotated in the direction of the arrow −R from the blocking position, the urging force (rotational power) for rotating the backflow restricting plate 142 in the direction of the arrow + R is applied by the torsion spring 136. ing.

  Here, with the axis center O as the boundary, the weight of the contact portion 142A including the rotation shaft 142C is Wt8, the weight of the balance portion 142B including the rotation shaft 142C is Wt9, and the weight member 146 is Wt10, and the game ball PB Each weight is set so as to meet an inequality of Wt8 ≦ (Wt9 + Wt10) <(Wt4 + Wt8) (hereinafter referred to as inequality C).

  The setting of the weights Wt4, Wt8, Wt9, and Wt10 using the inequality C is an example of the setting of the weight of each member. The moment including the length L3 of the contact portion 142A and the length L4 of the balance portion 142B, And the biasing force by the torsion spring 136 is also set. By setting the weight of each member in this manner, the backflow restricting plate 142 can be rotated in the arrow + R direction or the arrow −R direction without using a rotation driving means such as a motor.

  Further, in the state where the backflow restricting plate 142 is disposed at the blocking position (initial position), the distance between the lower surface 112D of the ball detection sensor 110 and the upper surface 142D of the backflow restricting plate 142 is Δd2, and the diameter of the game ball PB is d. In this embodiment, Δd2 is set so that 0 <Δd2 <d. This prevents the gaming ball PB with the thread 106 from moving back and forth up and down the ball detection sensor 110 while the backflow restricting plate 142 is held at the blocking position.

  Furthermore, a stopper member 116 is provided above the end portion (left end portion in the drawing) of the contact portion 142A of the backflow restricting plate 142. The stopper member 116 is configured to hold the backflow restricting plate 142 in the blocking position (initial position) by having the lower surface in contact with the upper surface 142D of the contact portion 142A.

  On the other hand, a plate-like detected portion 142E is erected at the center of the upper surface 142D in the depth direction at the end of the contact portion 142A. A photosensor 148 is provided on a bracket (not shown) provided close to the ball passage member 152 inside the pachinko machine 140 so as to surround the detected portion 142E in a U shape in plan view. The photo sensor 148 detects whether or not the backflow restricting plate 142 is in the blocking position (initial position) based on whether or not the detected portion 142E blocks light.

  For example, the photosensor 148 outputs an L signal when the light is blocked by the detected portion 142E, and outputs an H signal when the light is not blocked. The photosensor 148 is connected to the control unit 90 (see FIG. 4). In the control unit 90, when the H signal output from the photosensor 148 exceeds a preset set time, it is determined that the state is invalid, and the blinking display by the triple indicator lamp 64 or the warning sound from the speaker 50 is performed. Is set to output. The control unit 90, the detected portion 142E, and the photosensor 148 are an example of an opening time detection unit that detects the opening time of the backflow restriction plate 142.

  Next, the operation of the third embodiment will be described.

  As shown in FIG. 9A, when an illegal act in which the game ball PB with the thread 106 flows down from the side winning opening 102A through the ball passage 152A and through the ball passage 152B is performed, the game ball PB passes the ball detection sensor 110. The lower part of the inside game ball PB comes into contact with the contact part 142A of the backflow restricting plate 142 blocking the ball passage 152B. At this time, since the weight of the game ball PB acts on the contact portion 142A, the contact portion 142A (including the game ball PB) is heavier than the balance portion 142B, and the contact portion 142A is subjected to the urging force of the torsion spring 136. In opposition, the backflow restricting plate 142 rotates to the open position (arrow -R direction) to open the ball passage 152B. Further, an H signal is output from the photosensor 148.

  Then, the game ball PB with the thread 106 passes through the backflow restriction plate 142 when the backflow restriction plate 142 opens the ball passage 152B (flows downstream from the backflow restriction plate 142). Since the game ball PB with the thread 106 flows down in the ball passage 152B by its own weight, the backflow restricting plate 142 does not stop during the rotation to the open position, and the game ball PB with the thread 106 It will be located downstream of the backflow restricting plate 142 in the passage 152B.

  Subsequently, as shown in FIG. 9B, the weight of the game ball PB with the thread 106 does not act on the backflow restricting plate 142, and the total weight of the balance portion 142B and the weight member 146 is the weight of the contact portion 142A. Since it is heavier than that and the urging force of the torsion spring 136 is applied, it automatically rotates in the arrow + R direction. And the backflow control board 142 is hold | maintained in the interruption | blocking position because the edge part of the contact part 142A contacts the stopper member 116, and interrupts | blocks the ball path 152B again. In this manner, the stopper member 116 restricts the backflow restricting plate 142 from moving to the sphere detection sensor 110 side from the blocking position, so that the backflow restricting plate 142 is prevented from contacting the sphere detecting sensor 110. it can.

  Subsequently, when the fraudster pulls the thread 106 upward, the game ball PB with the thread 106 tries to move upward in the ball passage 152B. However, since the backflow restricting plate 142 blocks the ball passage 152B, the game ball PB with the thread 106 comes into contact with the lower surface of the backflow restricting plate 142 (contact portion 142A) to restrict movement, and the ball detection sensor 110 Will not pass through. In this way, the movement of the back-flowing game ball PB from the position downstream from the blocking position toward the upstream is restricted to the ball detection sensor 110, so that the game ball PB with the thread 106 moves the ball detection sensor 110. Passing multiple times is prevented, and cheating can be prevented.

  After the game ball PB with the thread 106 passes through the backflow restricting plate 142, the backflow restricting plate 142 is urged by the torsion spring 136 and rotates to the original position where the ball passage 152B is blocked. Compared to a configuration that does not provide the reverse flow restricting plate 142, the reverse flow restricting plate 142 can be returned to the original position in a short time.

  On the other hand, in the pachinko machine 140, for example, when a member different from the game ball PB with the thread 106 is used and the backflow restricting plate 142 is opened, the open state of the ball passage 152B is detected by the photosensor 148 and controlled. The H signal is output to the unit 90 (see FIG. 4). Then, the controller 90 counts the elapsed time since the H signal was input.

  Here, when the backflow restricting plate 142 is held in the open state and the elapsed time after the H signal is input exceeds the set time, the control unit 90 causes the triple indicator lamp 64 to blink or from the speaker 50. A warning is output to notify that the pachinko machine 140 is in an unauthorized state. In this way, even if a member different from the game ball PB with the thread 106 is used and the ball passage 152B is opened, an illegal state can be prevented. Further, in the control unit 90, when the elapsed time from the input of the H signal is within the set time, the triple indicator lamp 64 and the speaker 50 are operated in a normal gaming state (effect lighting operation, sound effect sound). Output operation).

  In FIG. 10A, the backflow restriction plates 100, 132, 142 in the first to third embodiments are disposed close to the lower side of the ball detection sensor 110 when the ball passages 108B, 152B are closed. (See Δd1 in FIG. 3A and Δd2 in FIG. 8A). Further, as shown in FIG. 10 (B), the backflow restricting plates 100, 132, 142 have a width W1 in the direction of arrow Y when viewed in plan, and the diameter W5 (> W1) of the passage hole 112A of the ball detection sensor 110. It is close to the size.

  Here, the difference (hereinafter referred to as ΔW (not shown)) between the diameter W5 of the passage hole 112A of the ball detection sensor 110 and the width W1 in the arrow Y direction of the backflow restricting plates 100, 132, 142 is the game ball PB. Is smaller than the diameter d (see FIG. 3A), and ΔW = (W5−W1) <d. Thus, in this configuration, as shown in FIG. 10B, a gap corresponding to the gap between the end portions of the backflow restricting plates 100, 132, 142 in the arrow Y direction and the hole wall of the passage hole 112A is provided. PB cannot pass from the lower side to the upper side. That is, even if the game ball PB with the thread 106 (see FIG. 3 (A)) below the backflow restricting plates 100, 132, 142 is pulled up, it cannot pass through the passage hole 112A. Can be prevented.

  In addition, this invention is not limited to said embodiment.

  In the pachinko machine 10, the game board 22 is an asymmetric gauge, but it may be a symmetric gauge. Each of the backflow restricting plates 100, 132, 142, if there is a space that can be rotated, is downstream of the ball detection sensor 110 in the ball path of the special symbol start winning holes 86A, 86B and the other side winning holes 102B, 102C. May be provided. Moreover, each backflow control board 100,132,142 is good also as the installation which makes not only the installation which makes the left-right direction a longitudinal direction, but also the front-back direction becomes a longitudinal direction when the pachinko machine 10, 130, 140 is viewed from the front. Further, the number of the back flow restricting plates 100, 132, 142 is not limited to one, and one may be provided on each of the left and right sides with the ball passage interposed therebetween, and may be an open door type.
