(Anti-fraud mechanism for gaming machines)
(Exemplary structure of fraud prevention mechanism and its installation position)
In the exemplary embodiment, the gaming machine 1 has the windmill 100 on the gaming board 2 as described above. In this embodiment, this windmill 100 is mounted as a structure provided with a fraud prevention mechanism. In general, the windmill is associated with a prize or a lottery (for example, the first start opening 21, the second start opening 22, the big winning opening 23, the normal winning opening 24, etc.) in relation to the function of distributing game balls. It is often provided upstream (in the flow of game balls flowing down). And fishing line goto is often performed using the windmill in such a position. The windmill 100 which concerns on one Embodiment of this invention has the function to perform the operation | movement which contributes to fraud prevention, when it fixes to such a position.

(Overall structure of windmill and layout on game board)
The structure of the windmill 100 will be described. The windmill 100 is attached to the game board 2 via a support shaft (shaft portion 102). And this windmill 100 can rotate centering | focusing on the said spindle with the blade member 1101 provided on the main surface.

  The structure of the wind turbine 100 will be described with reference to FIGS. 2 and 3. FIG. 2 is a schematic diagram illustrating a structure of a windmill 100 as an example of a structure (an accessory) including a fraud prevention mechanism. The upper side ((A)) of FIG. 2 shows an aspect in which a part of the structure of the windmill 100 is omitted. Moreover, the lower side ((B)) of FIG. 2 has shown in the aspect showing a part of below-mentioned blade member omitted by this upper side (B). The windmill 100 includes a blade member 101, a shaft portion 102, and a decorative plate 103. The blade member 101a, the blade member 101b, and the blade member 101c are partial structures of the blade member 101, and details thereof will be described later. The decorative plate 103 is a plate-like member having a substantially circular main surface. The decorative plate 103 includes a blade member 101 and a shaft portion 102 on one of its main surfaces, and an optional decoration is provided on the surface opposite to the surface on which these members are provided, if necessary. It has been subjected.

  In the present embodiment, the outer shape of the main surface of the decorative plate 103 is circular, but is not limited to this example, and may be another shape (for example, a polygon). Further, the shaft portion 102 provided on the main surface of the decorative plate 103 is positioned substantially at the center of the main surface of the decorative plate 103. The shaft portion 102 is a member extending in a direction perpendicular to the main surface of the decorative plate 103. In addition, the positional relationship of the shaft portion 102 with respect to the decorative plate 103 is not limited to the mode shown in the example, and other modes may be used as long as the decorative plate 103 can be rotated in a desired mode.

  In FIG. 2, the major axis direction of the shaft portion 102 is the z axis. The direction on the main surface side where the blade member 101 and the like are installed along the long axis is the positive direction of the z axis. In the gaming machine 1, the game board 2 is installed on the positive side of the z axis so as to be positioned in parallel with the main surface of the decorative board 103. In FIG. 2, the nail 104 is shown at the tip of the shaft portion 100 on the side opposite to the decorative plate 103, but when the nail is stuck in the main surface of the game board 2, the windmill 100 is The game board 2 is installed in such a manner that it can rotate around the shaft 102. That is, the shaft portion 102 functions as a support shaft of the wind turbine 100.

  In this example, the blade portion 101, the shaft portion 102, the decorative plate 103, and the (fixing) nail 104 exist as separate members, and are fixed to each other. However, as in this example, each member may not exist separately. That is, this windmill 100 may be provided as a structure integrally formed so as to have a function performed by each of the members constituting the windmill. Moreover, these members may be integrally formed partially.

(Structure of the blade member)
FIG. 2 shows a state where the blade member 101 is fixed to the decorative plate 103, but in FIG. 2A, a part of the blade member 101 is omitted. More specifically, FIG. 2A shows only one partial structure (blade member 101 a) that is a constituent unit of the blade member 101. Actually, two structures similar to the blade member 101a shown in FIG. 2A (that is, the blade member 101b or the blade member 101c in FIG. 2B) are left and right around the shaft portion 102. Are respectively installed at positions (region M12 or M23 in FIG. 2A) rotated about 120 degrees from the blade member 101a. These partial structures divide a region (space) on one surface of the decorative plate 103 into three regions (regions A1, A2, and A3 in FIG. 2). In this specification, the blade member 101a, the blade member 101b, and the blade member 101c are collectively referred to as the blade member 101. In addition, although the number of the partial structures of the blade member 101 is three in this example, in another embodiment, other numbers (for example, four etc.) may be sufficient.

  The wing member 101 has a shape capable of engaging with a thread-like object (for example, fishing line) illegally introduced into the game area 20. Specifically, the blade member 101 has a shape that can guide such a filamentous material into a space between the blade member 101 and the game board 2 and can be engaged with the filamentous material.

  More specifically, the blade member 101 is provided in a manner as shown in FIG. 3, for example. FIG. 3 is a schematic diagram for illustrating the shape of the windmill 100 shown in FIG. 2 and the positional relationship when the windmill 100 is fixed to the game board 2. Similarly to FIG. 2A, the blade member 101 is described with a part thereof omitted.

  A broken line shown in FIG. 3 is an auxiliary line indicating the position of the main surface of the game board 2. As described above, the main surface of the windmill 100 is fixed so as to be parallel to the main surface of the game board 2. For this reason, the main surface of the game board 2 is substantially perpendicular to the shaft portion 102 of the windmill 100.

  The shape of the blade member 101 a is defined depending on the relative positional relationship between the shaft portion 102 and the game board 2 when the windmill 100 is fixed to the game board 2. The decorative board 103 is fixed to the game board 2 and can rotate around a rotation axis (an axis substantially coincident with the major axis of the shaft portion 102) perpendicular to the main surface of the decorative board 103. The portion of the blade member 101a that is distal from the rotation shaft has a structure in which a distance from the game board 2 is secured as compared to the portion that is proximal. For example, in the configuration of FIG. 3, the blade member 101 a has an inclined surface facing the game board 2 (the arrow E in the figure) such that the distance from the game board 2 increases as the distance from the shaft portion 102 increases. Hereinafter, this surface is referred to as a “guided inclined surface”.

  In the example of FIG. 3, the guide inclined surface is defined as a plane. More specifically, the guide inclined surface is defined as a combination of planes in which the inclination angle (the angle formed between the game board 2 and the guide inclined surface) is changed stepwise. However, the guide inclined surface is not limited to a flat surface as in this example. That is, the guide inclined surface has a tendency that the distance from the game board 2 increases as it is more distal to the rotation axis (shaft portion 102) (the distance tends to be smaller as it is closer). If it is, it may be a curved surface.

  The main surface of the blade member 101a has a plurality of cut portions (one of which is indicated by the symbol C in FIG. 3) opened on the guide inclined surface side. In this example, the cut portion has a wedge shape that becomes narrower as the distance from the inclined guide surface increases.

(Operation of fraud prevention mechanism and its effect)
An example of operation when the windmill 100 having the above-described configuration functions as a fraud prevention mechanism will be described.

  First, a general game ball distribution function performed by the windmill 100 will be described. FIG. 4 is a schematic diagram showing the windmill 100 when the windmill 100 is viewed from the game board 2 side when the windmill 100 is fixed to the game board 2. The coordinate axes (xyz coordinate system) and the regions A1, A2 and A3 in the figure are the same as those in FIGS. In FIG. 4, the positive x-axis direction is the direction of the top of the gaming machine 1 (the direction in which the speakers 50 and the like are arranged), and the negative x-axis direction is the direction in which the game ball falls (vertical direction). .

  In a normal state, when a game ball is launched into the game area 20 by the gaming machine 1, the launched game ball is guided to an upper position of the game area 20. Then, the game ball falls along the game board 2 while changing its moving direction by coming into contact with an accessory such as a game nail or windmill 100 arranged in the game area 20. When the game ball falls in the game area 20 and is in a positional relationship where it interacts with the windmill 100, the game ball enters any of the areas A1 to A3 defined by the blade member 100 of the windmill 100. .

  A dotted line B in FIG. 4 shows an example of the outer shape of the game ball that has entered the area A3. Due to the effect of the weight of the game ball that has entered these areas, the windmill 100 rotates in the direction D1 or D2 with the shaft portion 102 as a rotation axis. As a result of this rotation, the game ball is discharged downstream from any of the areas A1 to A3. Depending on the rotation speed or the like, the game ball is changed in the moving direction in the process of falling in the game area 20.

  When an illegal game ball to which a thread-like object such as a fishing line is attached is launched into the game area 20 and reaches a position where it interacts with the windmill 100, the illegal game ball is divided into areas A1 to A3 in the same manner as a normal game ball. Can enter either. Then, the unauthorized gaming ball rotates the windmill 100 in the direction D1 or D2 by the action of the weight of the unauthorized gaming ball, and the unauthorized gaming ball itself moves downstream (in the negative x-axis direction) of the windmill 100. Move in the direction of flow.

  At this time, the fishing line attached to the unauthorized gaming ball is guided to the space between the guiding inclined surface and the main surface of the game board 2 facing the guiding inclined surface by the action of the guiding inclined surface of the blade member 100. In FIG. 4, an example of the space is shown as a region A4, and a fishing line is guided to the region as illustrated by an arrow FLW1.

  In this state, when a fraudster (introduced an illegal game ball) pulls one end of the fishing line, the action of the weight of the illegal game ball and the action of the force generally applied in the upstream direction (x-axis positive direction) Thus, the fishing line is drawn toward the shaft portion 102 side (for example, in the direction of the arrow FLW1) along the guide inclined surface. When the fishing line is applied to the cut portion, the fishing line is drawn into the depth of the cut portion of the blade member 100 (for example, the fishing line is drawn in the direction illustrated by the arrow FLW2).

  The cut portion becomes narrower (thinner) as it goes deeper from the guide inclined surface side, and a curved line is applied as necessary, so that the fishing line that has entered is fixed inside the cut portion. As a result, the fraudster cannot push and pull one end of fishing and operate the illegal gaming ball fished on the other end, and also captures the illegal gaming ball itself via the fishing line. It becomes possible. Then, by capturing the filaments used in such a fraudulent act, the fraudulent act can be suppressed and the fraudulent act can be easily found.

  In this example, of the sides of the blade member 101a, the length d (see FIG. 4) of the side distal to the shaft portion 102 and substantially parallel to the major axis of the shaft portion 102 is the size of the region A4. This is an amount that affects the definition of. For example, the length d is determined so as to secure a size that can easily guide the fishing line to the region A4 while avoiding the length in which the game ball is caught in the region A4 and is likely to be in a so-called sphere state. Good. In one example, the length d may be, for example, half or less than the diameter of the game ball.

(Modifications and other matters)
(Variation of blade member shape)
FIG. 5 is a schematic diagram showing a windmill 100 including a blade member 101a ′ having another shape that can be used as the blade member 101 described above. In this example, a part E ′ of the guiding inclined surface of the blade member 101 is defined as a curved surface. When a thread (for example, a fishing line) used for fraudulent acts contacts the guiding inclined surface E ′, the fishing line becomes deeper with a certain curvature (so that the fishing line is more easily guided to the cutting portion C ′ ( An inclination defined by a curved surface for guiding in the direction close to the decorative plate 103 is provided.

  The shape of the curved surface is not limited to the example shown in FIG. 5 as long as it is easy to guide the filamentous material behind the cut portion. In addition, the innermost part of the cut portion may have a space for stably positioning the filamentous material after the width is once narrowed. For example, it is the front-end | tip part P of the notch | incision part of an aspect as shown in FIG. FIG. 6 is a schematic diagram showing a cut portion C ″ as an example of the cut portion. In this schematic diagram, a circular space P is provided at the tip of the cut portion C ″ (the end opposite to the guide inclined surface) for capturing the filamentous material at that position. The filamentous material entering the space P makes it difficult to return the filamentous material in the direction opposite to the arrow in FIG. As a result, the situation in which the capture of the filamentous material is released can be further reduced.

  FIG. 7 shows a mode in which the decorative plate 103 of the windmill 100 has a cut portion (hereinafter, collectively referred to as a cut portion C ′ ″ in the present modified example) similar to the blade member 100. It is the schematic diagram which illustrates plate 103 'generically). When the blade member 101 has the cut portion C ′ ″ as illustrated in FIGS. 7A to 7C, the decorative plate 103 ′ of the windmill 100 has a function of capturing the filamentous material by the blade member 101. Can have. The decorative plate 103 ′ having such a configuration can be used together with the blade member 101 in order to capture the filamentous material, or can be used together with another blade portion that does not have a cut portion to constitute the windmill 100. .

  7A to 7C are schematic views showing the main surface of the circular decorative plate 103 ′ parallel to the paper surface. In the example of FIG. 7A, the cut portions C ′ ″ are provided so as to have a wedge shape toward the center from the edge of the decorative plate 103 ′ at substantially constant intervals along the circumference of the decorative plate 102. Yes. In the example of FIG. 7B, the cut portion C ″ ″ is provided to be a streamline-shaped groove from the edge of the decorative plate 103 ′ toward the center. In the example of FIG. 7C, the notch C '' 'has a structure similar to that shown in FIG. 6 that makes it difficult to separate the captured filamentous material. That is, the cut portion C '' 'of the decorative plate 103' has a structure in which the space is once narrowed from the circular edge toward the center, but a width wider than the most detail is secured at the tip. With this structure, the filament can be held more stably. In addition, the shape and the number of the cut portions C ′ ″ shown in each drawing are examples, and are not intended to be limited to the modes shown therein.

  Although the present invention has been described in detail above, the above description is merely illustrative of the present invention in all respects and is not intended to limit the scope thereof. It goes without saying that various improvements and modifications can be made without departing from the scope of the present invention. It is understood that the scope of the present invention should be construed only by the claims.
