The game ball is passed outside the gaming machine 1 through a passage sensor 66 in which the inlet side of the through hole is connected to the path 71 and a path 72 (hereinafter referred to as outlet side path 72) in which the outlet side of the through hole is connected. It falls to a predetermined position (not shown) for discharging. As a result, the game ball that has won the first start opening 25 a passes through the detection region X and is detected by the passage sensor 66. Hereinafter, a path constituted by the inlet side path 71, the passage sensor 66, and the outlet side path 72 is referred to as a detection path 73. In addition, each of the inlet side path 71 and the outlet side path 72 has a cylindrical shape. In FIG. 5, game balls passing through the detection path 73 are represented by dotted circles.

  FIG. 6 is a diagram for explaining in detail the wire rod fraud performed in the conventional structure described with reference to FIG. As described with reference to FIG. 3, an unauthorized person holds a game ball 65 to which one end of the wire 64 is attached (hereinafter, also referred to as an illegal game ball 65) while holding the other end of the wire 64 by hand. The game area 20 is struck and awarded to the first start opening 25a. The game ball 65 that has won the first start opening 25 a passes through the detection region X in the detection path 73 and exits from the exit of the detection path 73 once. A game ball 65 at a position E shown in FIG. 6 indicates the game ball 65 at the time of exiting from the exit of the detection path 73. Thereafter, the unauthorized person pulls up the game ball 65 located downstream of the position E or the position E upstream of the detection region X by pulling the other end of the wire 64 held in the hand. Then, the unauthorized person returns the pulled wire 64 to drop the game ball 65 at a position D downstream of the detection region X or further downstream. An unauthorized person passes the detection area X many times through the game ball 65 by repeating this unauthorized operation. As a result, the special symbol lottery is illegally executed, and the prize balls are illegally paid out, and the illegal person obtains illegal profits.

  FIG. 7 is a view for explaining an example of a characteristic structure of the first embodiment for preventing a wire rod fraud around the first start opening 25a, and is a longitudinal sectional view of this characteristic structure. The characteristic structure of this embodiment shown in FIG. 7 corresponds to the conventional structure shown in FIG. However, the characteristic structure of the present embodiment shown in FIG. 7 differs from the conventional structure shown in FIG. 5 in that a check valve 75 is provided in the outlet side path 72.

  FIG. 8 is a diagram for explaining an example of the shape of the check valve 75. FIG. 8A is a view showing the check valve 75 viewed from the same direction as FIG. FIG. 8 (2) is a view of the check valve 75 viewed from the M direction in FIG. 8 (1). FIG. 8 (3) is a view of the check valve 75 viewed from the N direction in FIG. 8 (1). As shown in FIG. 8, the check valve 75 includes a valve main body 76, a rotation shaft 77, and a weight portion 78. The rotation shaft 77 is a shaft for rotating (rotating) the check valve 75 and is rotatably supported by the outlet side path 72. The valve body 76 has a plate shape that can close the outlet-side path 72 and is fixed to the rotating shaft 77. The weight portion 78 has a relatively heavy weight member such as lead, for example, and is fixed to the rotating shaft 77. The weight portion 78 is pulled downward by gravity (that is, by its own weight), and the posture of the check valve 75 is the posture in which the valve body 76 shown in FIG. ). Further, the weight portion 78 is pulled downward by gravity to change the posture of the check valve 75, and the posture in which the valve body 76, which will be described later with reference to FIG. From the posture) to return to the closed posture.

  FIG. 9 is a diagram for explaining a mechanism in which a wire rod fraud is prevented by the check valve 75 described with reference to FIGS. 7 and 8. As shown in FIG. 9A, when the game ball 65 (or the illegal game ball 65) passes through the detection path 73 from the upper side to the lower side (that is, in the forward direction), the check valve 75 When 76 is pushed by the game ball 65, it rotates about the rotation shaft 77 as the central axis, and changes from the closed posture shown in FIG. 7 to the open posture. Thereafter, when the weight portion 78 is pulled by gravity and moves in the lower direction, the check valve 75 rotates about the rotation shaft 77 as a central axis. The closed posture shown in FIG. Here, consider a case where an unauthorized person tries to pull up the illegal game ball 65 once passing through the detection path 73 to the detection region X by pulling the wire 64. In this case, as shown in FIG. 9 (2), the illegal game ball 65 is pulled up in the detection path 73 by the wire 64, but hits the valve body 76 of the check valve 75 in the closed posture and is pulled up further. There is no. As shown in FIGS. 9 (1) and 9 (2), in the closed posture of the check valve 75, the distal end portion of the valve main body 76 comes into contact with the stepped portion provided on the inner wall of the outlet side path 72. There is no further upward movement. For this reason, the illegal gaming ball 65 does not return to the detection area X once passed, and as a result, the unauthorized person cannot obtain an unauthorized profit.

  As described above, in the first embodiment, by providing the check valve 75 on the downstream side of the passage sensor 66, the illegal game ball 65 that has once passed through the detection area X of the passage sensor 66 can be illegal. It is possible to prevent returning to the detection region X by the operation. As a result, wire rod fraud can be effectively prevented.

(Second Embodiment)
Hereinafter, a second embodiment of the present invention will be described. FIG. 10 is a view for explaining an example of a characteristic structure of the second embodiment for preventing a wire rod fraud around the first start opening 25a, and is a longitudinal sectional view of this characteristic structure. The characteristic structure of the second embodiment shown in FIG. 10 corresponds to the characteristic structure of the first embodiment shown in FIG. However, the characteristic structure of the present embodiment shown in FIG. 10 differs from the characteristic structure of the first embodiment shown in FIG. 7 in the position where the check valve is provided in the detection path 73. In the following, content different from the first embodiment will be described.

  As shown in FIG. 10, in the first embodiment shown in FIG. 7, the check valve 75 is provided in the outlet side path 72, whereas in the second embodiment, the check valve 85 is provided in the inlet side path 71. Provided. That is, in the second embodiment, the check valve is provided on the upstream side (upper side) of the passage sensor 66 in the detection path 73.

  FIG. 11 is a view for explaining an example of the shape of the check valve 85. FIG. 11 (1) is a view showing the check valve 85 viewed from the same direction as FIG. FIG. 11 (2) is a view of the check valve 85 viewed from the M direction in FIG. 11 (1). FIG. 11 (3) is a view of the check valve 85 viewed from the N direction of FIG. 11 (1). As shown in FIG. 11, the check valve 85 includes a protrusion 86 (a sandwiched protrusion) formed on the distal end surface of the valve main body 76 of the check valve 75 shown in FIG. This is a shape to which an example of a part is added.

  FIG. 12 is a diagram for explaining a mechanism in which wire rod fraud is prevented by the check valve 85 described with reference to FIG. 11. Similarly to the description using FIG. 9A, when the game ball 65 (or the illegal game ball 65) passes through the detection path 73 from the upper side to the lower side, the check valve 85 has the valve body 76 as the game ball. When it is pushed by 65, it rotates about the rotation shaft 77 as the central axis, and changes from the closed posture to the open posture. Thereafter, when the weight portion 78 is pulled by gravity and moves downward, the check valve 75 rotates about the rotation shaft 77 and returns to the closed posture shown in FIG. .

  Here, consider a case where an unauthorized person tries to pull up the illegal game ball 65 once passing through the detection path 73 to the detection region X by pulling the wire 64. In this case, as shown in FIG. 12 (1), the wire 64 is sandwiched between the valve body 76 and the inner wall of the inlet side passage 71. This will be described in detail below. FIG. 12B is an enlarged view of the periphery of the protrusion 86 indicated by the ellipse (broken line portion) in FIG. As shown in FIG. 12 (2), the wire rod 64 is sandwiched between the protrusion 86 on the distal end surface of the valve body 76 and the inner wall of the inlet-side passage 71 by being pulled by an unauthorized person (that is, bitten). ) Thus, in principle, the wire rod 64 is fixed, and an unauthorized person cannot lift the wire rod 64 any further. As shown in FIG. 12 (2), in the closed posture of the check valve 85, the tip portion of the valve body 76 comes into contact with the step provided on the inner wall of the inlet side passage 71, so that it is further upward. Never move. From the above, as shown in FIG. 12 (1), the illegal gaming ball 65 is not lifted any more in principle, so it does not return to the detection area X that has passed once. Can't get a good profit.

  FIG. 13 shows a case where the illegal gaming ball 65 is pulled up to just below the check valve 85 as an exception as a result of the unauthorized person pulling the wire 64 strongly in the state shown in FIG. Show. However, in this case, as shown in FIG. 12 (2), the wire 64 is sandwiched between the inner wall of the inlet-side passage 71 and the protrusion 86 of the valve body 76, so that even if an unauthorized person loosens the wire 64. With the weight of the illegal game ball 65, the illegal game ball 65 does not move downward. For this reason, even if an unauthorized person pulls or loosens the wire 64, the unauthorized gaming ball 65 does not move from the position shown in FIG. 13, and as a result, the unauthorized person cannot obtain an unauthorized profit.

  As described above, in the second embodiment, by providing the check valve 85 on the upstream side of the passage sensor 66, the illegal gaming ball 65 that has once passed through the detection region X of the passage sensor 66 can be illegal. In principle, it is possible to prevent returning to the detection region X by an action. In addition, even if the illegal game ball 65 returns to the detection area X as an exception because the unauthorized person has pulled the wire 64 strongly, the illegal game ball 65 may move again downstream (downward). There is no. As a result, according to the second embodiment, the wire fraud can be effectively prevented.

(Third embodiment)
Hereinafter, a third embodiment of the present invention will be described. FIG. 14 is a view for explaining an example of the characteristic structure of the third embodiment for preventing the wire rod fraud around the first start opening 25a, and is a longitudinal sectional view of this characteristic structure. The characteristic structure of the third embodiment shown in FIG. 14 corresponds to the characteristic structure of the first embodiment shown in FIG. However, the characteristic structure of the present embodiment shown in FIG. 14 differs from the characteristic structure of the first embodiment shown in FIG. 7 in the structure of the check valve. In the following, content different from the first embodiment will be described.

  As shown in FIG. 14A, the third embodiment includes a check valve 95 instead of the check valve 75 of the first embodiment shown in FIG. The check valve 95 includes a first valve body 96, a second valve body 97, a first spring 98, and a second spring 99. The first spring 98 and the second spring 99 are coil springs. FIG. 15 is a view for explaining an example of the shape of the second valve body 97. The shape of the first valve body 96 is the same as the shape of the second valve body 97. FIG. 15 (1) is a diagram showing the second valve body 97 viewed from the same direction as FIG. 14 (1). FIG. 15 (2) is a view of the second valve body 97 viewed from the M direction in FIG. 15 (1). FIG. 15 (3) is a view of the second valve body 97 viewed from the N direction in FIG. 15 (1). As shown in FIG. 15, the second valve body 97 has a rectangular parallelepiped shape (or cube) cut in a plane so as to cut out two vertices thereof, and the bottom face and the top face have the same shape by this cut. This is a shape in which a triangular prism is cut out. Hereinafter, a plane formed by this cutting is referred to as a pushing surface. The second valve body 97 has a belt-like contact surface (an example of a clamping portion), and this contact surface contacts the contact surface of the first valve body 96 (see FIG. 14 (1)). As shown in FIG. 14 (1), the outlet path 72 accommodates the first accommodating portion 91 that accommodates the first valve body 96 and the first spring 98, and the second valve body 97 and the second spring 99. A second housing portion 92 is formed. Then, as shown in FIG. 14 (1), the first valve body 96 is pushed into the outlet side path 72 by the repulsive force of the first spring 98, and the second valve body 97 is discharged by the repulsive force of the second spring 99. Pushed into the side path 72, the contact portion of the first valve body 96 and the contact portion of the second valve body 97 abut. Hereinafter, such a posture of the check valve 95 that closes the detection path 73 is referred to as a closed posture.

  Next, a mechanism in which the check valve 95 in the closed posture shown in FIG. 14A is in an open posture in which the detection path 73 is opened will be described. As shown in FIG. 14 (2), the game ball 65 (or the illegal game ball 65) falling from the upstream side (upper side) to the downstream side (lower side) is a pushing surface of the first valve body 96 and the second valve body. The pushing surface of 97 (see FIG. 15) is pushed, whereby the first valve body 96 is pushed and moved in the left direction, and the second valve body 97 is pushed and moved in the right direction. As a result, as shown in FIG. 14 (2), the check valve 95 is in the open posture, and the game ball 65 (or the illegal game ball 65) passes through the detection path 73.

  Next, consider a case where an unauthorized person tries to pull up the unauthorized gaming ball 65 once passing through the detection path 73 to the detection region X by pulling the wire 64. In this case, as shown in FIG. 14 (3), the illegal game ball 65 hits the check valve 95 (that is, the first valve body 96 and the second valve body 97) in the closed posture and is not pulled up any further. For this reason, the illegal gaming ball 65 does not return to the detection area X once passed, and as a result, the unauthorized person cannot obtain an unauthorized profit.

  As described above, in the third embodiment, by providing the check valve 95 on the downstream side of the passage sensor 66, the illegal gaming ball 65 that has once passed through the detection area X of the passage sensor 66 can be illegal. It is possible to prevent returning to the detection region X by the operation. As a result, wire rod fraud can be effectively prevented.

(Fourth embodiment)
Hereinafter, a fourth embodiment of the present invention will be described. As shown in FIG. 16, the fourth embodiment has a configuration in which a check valve 95 is provided on the upstream side (upper side) of the passage sensor 66 with respect to the third embodiment described with reference to FIG. 14. .

  In this configuration, let us consider a case where an unauthorized person pulls up the illegal game ball 65 that has once passed through the detection path 73 to the detection region X by pulling the wire 64. In this case, as shown in FIG. 16, the wire 64 is sandwiched between the contact surface of the first valve body 96 and the contact surface of the second valve body 97, so that even if an unauthorized person loosens the wire 64. With the weight of the illegal game ball 65, the illegal game ball 65 does not move downward (does not fall). In order to prevent the unauthorized gaming ball 65 from falling in this manner, for example, the contact surface of the first valve body 96 and the contact surface of the second valve body 97 may be formed with an uneven shape. For this reason, even if an unauthorized person pulls or loosens the wire 64, the unauthorized gaming ball 65 does not move from the position of FIG. 16, and as a result, the unauthorized person cannot obtain an unauthorized profit.

  As described above, in the fourth embodiment, by providing the check valve 95 on the upstream side of the passage sensor 66, the illegal gaming ball that has once passed through the detection region X due to the unauthorized person pulling the wire 64. When 65 returns to the detection region X, it is possible to prevent the illegal gaming ball 65 from moving again downstream (downward). As a result, according to the fourth embodiment, the wire rod fraud can be effectively prevented.

[Modification]
In the second embodiment described above, the protrusion 86 is provided in order to sandwich the wire 64 between the distal end surface of the valve body 76 and the inner wall of the inlet side passage 71 (see FIG. 12). However, the wire rod 64 may be sandwiched between the distal end surface of the valve main body 76 and the inner wall of the inlet side passage 71 without providing the protrusion 86. For example, in the closed posture of the check valve 85, the wire rod may be sandwiched with a configuration in which there is no gap between the distal end surface of the valve body 76 without the protrusion 86 and the inner wall of the inlet-side passage 71.

  Further, in the above-described second embodiment, as shown in FIG. 11, the protrusion 86 is provided only on the distal end surface of the valve body 76. However, the protrusion 86 may be provided not only on the front end surface of the valve body 76 but also on the entire outer peripheral side surface. This makes it possible to sandwich the wire 64 more reliably.

  Further, the protrusion 86 (see FIG. 12 (2)) is not provided at the distal end portion of the valve body 76 as in the second embodiment described above, but the distal end portion of the valve body 76 as shown in FIG. The wire 64 may be sandwiched by providing a notch. This will be specifically described below. FIG. 18 (1) corresponds to FIG. 12 (2), and is a diagram for explaining a position where the cut is provided. As shown in FIG. 18 (1), a notch is provided at the tip of the valve body 76 indicated by a dotted oval F. FIG. 18 (2) is a view showing notches provided in the tip portion of the valve body 76. As shown in FIGS. 18 (1) and (2), this notch is a notch in which the distal end surface, the upper surface, and the lower surface of the valve body 76 are opened, and gradually increases in the proximal direction of the valve body 76. The shape has a smaller width. As a result, the wire 64 is sandwiched between the cuts, and the same effect as in the second embodiment is obtained. In FIG. 18, a plurality of cuts are provided at the tip of the valve body 76, but the number of cuts may be one or more. Further, this notch may be provided not in the tip end portion of the valve body 76 indicated by the dotted ellipse F in FIG. 18B but in the portion of the inlet side path 71 indicated by the dotted ellipse G (step-shaped portion). Good. Furthermore, this notch may be provided in both portions of the dotted ellipses F and G.

  In the first and second embodiments described above, the check valve 75 (85) is returned from the open posture to the closed posture by the weight portion 78 (see FIGS. 8 and 11), and the closed posture is maintained. . However, the means for returning from the open posture to the closed posture and maintaining the closed posture is not limited to this, and may be, for example, an elastic member such as a spring.

  In the third and fourth embodiments described above, the check valve 95 is returned from the open position to the closed position by the first spring 98 and the second spring 99, and the closed position is maintained. However, the means for returning from the open posture to the closed posture and maintaining the closed posture is not limited to this, and may be, for example, an elastic member such as rubber.

  In the third and fourth embodiments described above, the check valve 95 is configured by the pair of valve bodies (96, 97) and the pair of springs (98, 99). However, for example, as shown in FIG. 17, the check valve 95 may be configured by the second valve body 97 and the second spring 99.

  In the first to fourth embodiments described above, the inner peripheral shapes of the inlet-side passage 71 and the outlet-side passage 72 have been described as being quadrangular, so the shapes of the check valves 75, 85, and 95 are The shape shown in FIGS. 8, 11 and 15 that can close the path has been described. However, the check valves 75, 85, and 95 may have any shape as long as the path can be closed. If the inner peripheral shape of the path is, for example, a circle, the check valves 75, 85, and 95 are appropriately changed according to the shape. Yes. The “blocking” referred to here may be a blockage that can achieve the effects of the first to fourth embodiments described above, and does not mean that the blockage is completely blocked without a gap.

  Moreover, in the above-described first to fourth embodiments, the case where the first start port 25a is provided with a check valve has been described as an example. However, the check valve may be provided in other portions that detect the passage of the game ball, such as the second start port 25b, the normal winning port 29, the big winning port 28, and the gate 27. In other words, the check valve may be provided in a portion where the player can benefit from the passage of the game ball.

  In the first to fourth embodiments described above, as illustrated in FIG. 8 and the like, the passage sensor 66 has been described as an example of a configuration that detects a game ball falling directly below. However, the passage sensor 66 may be configured to detect a game ball that moves from the upstream toward the downstream on the detection path 73. For example, the passage sensor 66 may be configured to detect a game ball that rolls obliquely downward.

  In the first to fourth embodiments, the inductive proximity switch described with reference to FIG. 4 is used as an example of the passage sensor 66. However, the passage sensor 66 may be of another detection method as long as it can detect a game ball passing through the detection path 73. For example, the passage sensor 66 may be an optical sensor that detects the passage of a game ball using the fact that light is blocked by the game ball that passes through the detection path 73. Further, for example, the passage sensor 66 may be a mechanical sensor that detects the passage of the game ball by using the movement of the switch member when the switch member hits the game ball passing through the detection path 73. .

  In the above-described embodiment, the size of the detection region X of the passage sensor 66 is not limited to the size shown in FIG.

  Further, the shape, number, installation position, etc. of each component provided in the pachinko gaming machine 1 described above are merely examples, and other shapes, numbers, installation positions, etc. It goes without saying that the present invention can be realized without departing from the scope.

  As mentioned above, although this invention was demonstrated in detail using embodiment, the above-mentioned description is only the illustration of this invention in all the points, and does not intend to limit the range. It goes without saying that various improvements and modifications can be made without departing from the scope of the present invention. In addition, it is to be understood that the terms used in the present specification are used in the meaning normally used in the art unless otherwise specified. Thus, unless defined otherwise, all technical and technical terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. In case of conflict, the present specification, including definitions, will control.

[Example of effects of the above embodiment]
In the embodiment described above, the check valves (75, 85, 95) are arranged in the vicinity of the passage sensor 66 that detects that the game ball 65 has passed through the detection area X in the detection path 73 of the game ball. Accordingly, even if the unauthorized person pulls the wire 64, the unauthorized game ball 65 cannot be lifted upstream from the check valve (75, 85, 95), so the passing sensor 66 detects the unauthorized game ball 65 many times. Wire fraud can be effectively prevented.

  Further, the check valve (75, 85, 95) is pushed by the game ball 65 passing in the forward direction through the detection path 73 and changes its posture from the closed posture to the open posture, and the biasing means (78, 98, 99). ) Changes the posture of the valve body (76, 96, 97) to return it from the open posture to the closed posture. This ensures that the check valves (75, 85, 95) function to reliably pass the game ball in the forward direction and not in the reverse direction.

  Further, the check valves (85, 95) may be arranged on the upstream side of the passage sensor 66 in the detection path 73 (FIGS. 12 and 16). Accordingly, it is possible to effectively prevent a wire rod fraud that causes the passage sensor 66 to detect the illegal game ball 65 many times.

  Furthermore, in the configuration in which the check valve (85, 95) is disposed on the upstream side of the passage sensor 66, the illegal game ball 65 that has passed through the detection path 73 in the forward direction is included in the check valve (85, 95). It is desirable to provide a holding part (protrusion part 86 in FIG. 11, contact surface in FIG. 15) that prevents the unauthorized gaming ball 65 from moving in the forward direction across the wire 64 attached to the board. As a result, it is possible to prevent the illegal gaming ball 65 pulled up by an unauthorized person from moving again downstream, and thus it is possible to more reliably prevent wire fraud.

  Further, the check valves (75, 95) may be disposed on the downstream side of the passage sensor 66 in the detection path 73 (FIGS. 7 and 14). Accordingly, it is possible to effectively prevent a wire rod fraud that causes the passage sensor 66 to detect the illegal game ball 65 many times.

  Further, the check valves (75, 85) are returned from the open posture to the closed posture when the weight portion 78 is lowered by its own weight (FIG. 9 and the like). This makes it possible to configure a check valve that functions reliably with a simple structure.

  Further, the valve body (96, 97) is at least partly protruded from the first position (the posture shown in FIG. 14 (2)) where the whole is stored in the storage portion (91, 92) and the storage portion. The posture may be changed by moving between the second position (the posture shown in FIG. 14 (1)), and the check valve 95 may be returned to the closed posture by a spring (98, 99). This makes it possible to configure a check valve that functions reliably.
