Description

  The present invention relates to a gaming machine.

  Conventionally, a circuit board provided in a gaming machine such as a pachinko gaming machine is accommodated in a transparent board case to prevent fraud. In addition, the substrate case may employ a sealing structure that cannot be opened unless it is destroyed, such as a caulking structure, so that it is possible to easily determine whether fraud has been performed. A seal that leaves a trace that has been peeled off across the boundary of the case body may be applied.

Further, a seal including an IC chip and an antenna has been proposed in order to easily detect fraud (see, for example, Patent Document 1). The seal described in Patent Document 1 includes an antenna having brittleness that is partially broken by the stress accompanying the peeling force. If an illegal act is performed, the antenna is destroyed, so that communication with an external reader becomes impossible, and it is possible to detect the illegal act without visual inspection.
JP 2006-305037 A

  However, the conventional technology has a problem that fraudulent detection can be avoided by carefully removing the seal. For example, Patent Document 1 proposes a seal having a structure in which the antenna is easily broken when the seal is peeled off, but the seal can be directly touched and can be communicated with the reader in some way. The possibility of being taken remains.

  The present invention has been made to solve the above problems, and an object of the present invention is to provide a gaming machine that can more reliably detect fraud with respect to a circuit board.

  In order to achieve the above object, a gaming machine according to the present invention is a gaming machine in which a board for controlling the gaming machine is accommodated in a board case, and the board case is attached to a gaming machine main body. A base body opposed to the gaming machine main body, and a cover body that opens and closes an accommodation space of the substrate case by being displaced with respect to the base body, and the gaming machine main body of the outer surface of the base body Between the first surface that is a portion facing the first surface and the second surface that is the portion facing the first surface of the outer surface of the gaming machine body, and one surface is fixed to the first surface, and the other An RF tag having a surface fixed to the second surface is provided, and the gaming machine main body has a regulating wall that is positioned in a displacement direction of the cover body and regulates displacement of the cover body with respect to the base body.

  Thus, the regulation wall is provided in the gaming machine main body facing the base body of the board case, and the RF tag is fixed between the base body and the gaming machine main body. Therefore, in order for a person who intends to cheat on the board accommodated in the board case to open the board case, the board case must be moved from the gaming machine body so as to avoid the restriction by the restriction wall. One surface of the RF tag is fixed to a first surface that is a portion facing the gaming machine main body of the outer surface of the base body, and the other surface of the RF tag is a gaming machine facing the first surface of the outer surface of the gaming machine main body. Since it is fixed to the second surface, which is a part of the main body, when the board case is moved from the gaming machine main body, tension or shear force is applied to the RF tag. This tension or shearing force separates the antenna from the IC chip, divides the antenna itself, or distorts the shape of the antenna. For this reason, communication between the RF tag and the reader becomes impossible. Therefore, since an abnormality occurs in communication with the reader, the reader user can easily know fraud based on the reception of the reader.

  Embodiments according to the present invention will be described below with reference to the drawings.

  FIG. 1 is a perspective view showing a pachinko gaming machine 100 of the present embodiment from the front direction.

  As shown in the figure, the pachinko gaming machine 100 includes an outer frame 11, a front frame 12, and a glass door 13, and a back of the glass door 13 includes a game board 14 on which a game ball 5 falls. Yes.

  The outer frame 11 is a frame that serves as a basis for holding each component of the pachinko gaming machine 100, and is a rectangular frame. A curtain plate 31 is provided integrally with the outer frame 11 so as to cover the lower front surface of the outer frame 11. The outer frame 11 is a member that is directly fixed to the installed Tajima such as a pachinko hall, and the pachinko gaming machine 100 is installed on the Tajima by fixing only the Tajima and the outer frame 11. .

  The curtain 31 is provided to secure a space where the front frame 12 can be opened in a state where a box (so-called dollar box) for transporting the game ball 5 is arranged below the lower plate 17 for storing the game ball 5. A member such as a speaker (not shown) for production may be attached to the curtain 31.

  The front frame 12 as a gaming machine main body is a member to which the game board 14 and the like, various control boards, and the like are attached directly or indirectly through attachment members. The front frame 12 is attached to the left side of the front end surface of the outer frame 11 and the hinge 1 and has a door shape that allows the front frame 12 to rotate with respect to the outer frame 11. That is, when the front frame 12 of the pachinko gaming machine 100 installed on Taijima is rotated like a door, the pachinko gaming machine 100 can be opened to expose the back.

  In addition, an upper plate 16 and a lower plate 17 for storing the game balls 5 that can be operated by the player are provided in the lower front portion of the front frame 12, and the player rotates the right side of the lower plate 17 by rotating the player. A handle 18 for selecting whether or not the game ball 5 can be ejected and for changing the ejection speed of the game ball 5 is provided.

  The glass door 13 is a member attached to the front surface of the front frame 12 via the hinge 2. The glass door 13 has a circular hole-shaped window 3, and a glass plate is attached so as to cover the window 3 from the back.

  The game board 14 is a member made of wood or resin for forming a game area in which the game ball 5 falls, and a start for triggering a nail or a jackpot for judging the game ball 5 to fall in a complicated manner. In addition to the mouth 15 and the big prize opening 19 that is opened to receive the game ball 5 during the jackpot game, the display device 21 on which decorative symbols are displayed is attached. In addition, a display device 21 for displaying a game-related symbol is attached to the center of the game board 14.

  Here, the start port 15 attached to the game board 14 is a variable type start port provided with wings that can be opened and closed on the left and right. Opening and closing of the wings is controlled by a driving source and a driving mechanism provided on the back surface of the game board 14. In the state where the wings are opened, the game ball 5 can win the start opening 15 with higher probability than in the state where the wings are closed.

  FIG. 2 is a perspective view showing the pachinko gaming machine 100 from the back side.

  As shown in the figure, the pachinko gaming machine 100 includes a display sub-board 105 that performs display control using a decorative lamp and a liquid crystal display, an audio board 106 that controls output of various sounds, and a pachinko gaming machine at the time of winning a prize. Various substrates including a main board 107 that controls the main operations of the pachinko gaming machine including the operation, a payout board 108 that controls the payout operation of the game balls, and a power supply board 109 that supplies power to each board are transparent. It is mounted in a state of being housed in a simple board case. For example, a board case (hereinafter referred to as “main board case”) 110 that houses the main board 107 is attached to the front frame side attachment surface (115a) of the front frame 12 as a gaming machine body.

  FIG. 3 is a diagram showing a configuration of a main board case 110 that houses a main board and a mode in which the main board case 110 is attached to a front frame 12 as a gaming machine main body.

  The main board case 110 includes a cover body 110a and a base body 110b as shown in FIG.

  The cover body 110a is assembled integrally with the base body 110b by fitting both ends of the cover body 110a into the grooves 116 of the base body 110b and sliding the cover body 110a. The cover body 110a is assembled so as to close the accommodation space in which the main board 107 (not shown) is accommodated.

  Further, the cover body 110a is displaced with respect to the base body 110b by sliding movement. When the cover body 110a is displaced with respect to the base body 110b, the accommodation space of the main board case 110 is opened and closed.

  Due to the structure of the main board case 110, in order to perform an illegal act on the main board 107, a space for sliding the cover body 110a is required in order to make the main board case 110 open.

  The main board case 110 is attached to the front frame 12 as a gaming machine main body by screws 113.

  In the base body 110b of the main board case 110, the bottom surface 110c of the base body 110b as the first surface of the outer surface of the base body 110b faces the front frame 12 as the gaming machine main body. Further, in the front frame 12 as the gaming machine main body, the front frame side mounting surface 115a as the second surface of the outer surface of the front frame 12 faces the bottom surface 110c as the first surface.

  Note that the gaming machine main body to which the main board case 110 is attached is not limited to the front frame 12, but may be a gaming board 14, a main set to which various components of the gaming machine are attached, a ball cage that forms a flow path for gaming balls, or the like. . Moreover, the 2nd surface which is the bottom face 110c of the base body 110b as a 1st surface should just be a part in which the main board case 110 can be attached among the outer surfaces of the member which comprises a game machine main body.

  The obstacle 111 is a wall fixed to the front frame 12. The obstacle 111 has a certain height. FIG. 3 shows the obstacle 111 with a part cut away.

  The obstacle 111 is in a direction in which the cover body 110a is slid when the accommodation space of the main board case 110 is released, and the main board case 110 is attached to the front frame 12 with respect to the base body 110b of the cover body 110a. It functions as a regulating wall that regulates displacement. Therefore, the obstacle 111 has a height that can restrict the displacement of the cover body 110 a attached to the front frame 12.

  When the main board case 110 is attached to the front frame 12, one surface in the sliding direction of the cover body 110a assembled to the base body 110b comes into contact with the obstacle 111. By being attached in this way, the main board case 110 cannot be released unless it is removed from the front frame 12.

  The obstacle 111 is preferably provided integrally with the front frame 12 as a gaming machine main body. By being provided integrally with the front frame 12, it becomes difficult to attach and detach the obstacle 111, so that the opening of the main board case 110 can be effectively prevented.

  The obstacle 111 may be various components of the gaming machine such as other board cases.

  The RF tag 112 includes an IC chip that stores identification information, which is information unique to the RF tag 112, and an antenna that transmits and receives radio waves to and from an external reader. The RF tag 112 has a communication function with the reader by force applied from the outside. It has the vulnerability of being easily destroyed so as to be damaged.

  As shown in FIG. 4, the RF tag 112 is disposed between the bottom surface 110c of the main board case 110 as the first surface and the front frame side mounting surface 115a as the second surface.

  The RF tag 112 is coated with an adhesive on both sides. One surface 112a of the RF tag 112 is fixed to the bottom surface 110c of the base body 110b as the first surface by an adhesive applied thereto. The other surface 112b of the RF tag 112 is fixed to the case-side mounting surface 110c with an adhesive applied thereto.

  As a result, when the main board case 110 is attached to the front frame 12, the RF tag 112 is fixed in a bridging manner between the bottom face 110c of the main board case 110 and the front frame side attachment face 115a.

  As described above, in order to open the accommodation space of the main board case 110, it is necessary to slide the cover body 110a in the arrow direction shown in FIG. In a state where the main board case 110 is attached to the front frame 12, the cover body 110a cannot be removed and the accommodation space for the main board case 110 cannot be opened because there is an obstacle 111.

  In order to release the accommodation space of the main board case 110, it is necessary to remove the screw 113 of the main board case 110 and move the main board case 110 to a position where the cover body 110a can slide without being obstructed by the obstacle 111. There is. When the main board case 110 is removed from the front frame 12 in order to move the main board case 110, the RF tag 112 cannot be communicated with the reader.

  That is, since both surfaces of the RF tag 112 are fixed to the bottom surface 110c and the front frame side mounting surface 115a of the main board case 110, when the main board case 110 is moved, the RF tag 112 is subjected to tension and shearing force. Take it. The RF tag 112 can communicate with a reader because an antenna having a certain shape is connected to the IC chip. However, since the RF tag 112 is subjected to a force, the RF tag 112 has a weakness, and the antenna is thus integrated with the IC. It may be separated from the chip, the antenna may be disconnected, or the shape of the antenna may be distorted. As a result, the RF tag is destroyed and communication with the reader becomes impossible.

  In this way, by providing the obstacle 111 that restricts the release of the accommodation space of the main board case 110, it is almost impossible to perform illegal acts on the main board 107 with the main board case 110 attached to the front frame 12. It becomes possible. Further, by fixing the RF tag 112 to the bottom surface 110c of the base body 110b, the RF tag 112 is inevitably destroyed at the time of release, and an illegal act can be easily detected using a reader.

  FIG. 6 is a diagram showing a reader 210 for detecting fraud.

  The reader 210 includes a reading unit 210a that transmits and receives radio waves and a main body 210b that detects an abnormality of the RF tag 112. The main body 210b has a storage medium (not shown), and in the storage medium, related information that associates the identification information unique to the RF tag 112 and the pachinko gaming machine 100 one-on-one is stored and registered.

  The user turns on the reader 210 and holds the reader 210a of the reader 210 over the pachinko gaming machine 100. Thereby, when the reading unit 210a receives a radio wave as a response from the RF tag 112 of the pachinko gaming machine 100, the main body 210b of the reader 210 collates the identification information included in the radio wave with the related information, Detect fraud. Specifically, when the radio wave as a response is not received, and when the identification information included in the radio wave received as a response is not registered in the storage medium, it is determined that the RF tag 112 is abnormal, and an illegal act Is detected.

  The main body 210b determines that there is no abnormality in the RF tag 112 when the identification information included in the radio wave received as a response is registered in the storage medium, and determines that there is no fraud. “OK” shown in the main body 210b of FIG. 6 is an example of a display indicating that there is no fraud on the display.

  Such a display allows the user to know the detected fraud.

  Here, the RF tag 112 is also destroyed when an authorized dealer or the like removes the main board case 110 from the front frame 12 for maintenance of the main board 107 or the like. If it is an authorized person, a new RF tag 112 is fixed.

  Here, the identification information stored and held in the IC chip of the new RF tag 112 is different from the identification information stored and held in the IC chip of the original RF tag 112. The identification information stored and held in the IC chip of the new RF tag 112 is registered in a device that manages the reader 210 or the pachinko gaming machine 100 as related information for associating it with the pachinko gaming machine.

  Note that at least a part of the RF tag 112 only needs to be fixed to each of the bottom surface 110c of the main board case 110 and the main body side attachment surface 115a of the front frame 12.

  FIG. 7 is a diagram showing a modification of the method for fixing the RF tag.

  The RF tag 212 shown in the figure has an adhesive 213b applied to a part of one surface and an adhesive 213a applied to a part of the other surface. One surface of the RF tag 212 is fixed to the bottom surface 110c of the base body 110b as the first surface by an adhesive 213b. The other surface of the RF tag 212 is fixed to the front frame side mounting surface 115a as the second surface by an adhesive 213a.

  As described above, the RF tag 212 is disposed between the bottom surface 110c of the base body 110b as the first surface and the front frame side mounting surface 115a as the second surface, and the main board case 110 is fixed from the front frame 12. Each of the outer surface of the main board case 110 and a part of the outer surface of the front frame 12 as a gaming machine main body has such a strength that a tension or a shearing force is applied to itself with a certain strength or more when moved. It only has to be fixed to.

  Note that the vicinity of the entrance of the screw hole 114 of the front frame 12 shown in FIG. 3 is subjected to a taper process in which the diameter decreases from the entrance of the screw in the depth direction. As a result, the screw 113 is guided to the screw hole 114. When the positional relationship between the screw 113 and the screw hole 114 is adjusted in a state where the RF tag 112 is sandwiched between the front frame 12 and the main board case 110, the RF tag 112 is attached to the front frame side mounting surface 115a and the base body 110b. There is a risk of being destroyed because it is rubbed with the bottom surface 110c. By providing a guide for guiding the main board case 110 near the entrance of the screw hole 114 to the mounting position of the gaming machine main body such as the front frame 12, the RF tag 112 is sometimes attached to the main board case 110. It is possible to prevent destruction.

  Such a guide may be realized by fitting a positioning protrusion for positioning provided on the bottom surface of the main board case and a positioning hole provided in the gaming machine main body. As a result, it is possible to prevent the RF tag from being destroyed when the main board case 110 is attached.

  The present invention can be applied to a substrate case that opens and closes in a sliding manner regardless of the type of substrate. This makes it possible to more reliably detect fraudulent acts on each substrate.

  The substrate case may have a shape that opens and closes like a hinged door.

  FIG. 8 is a view showing an example of such a hinged door type substrate case 310.

  The substrate case 310 of this figure is composed of a base body 310b and a cover body 310a.

  The cover body 310a is displaced with respect to the base body 310b by rotating about the shaft 310c. When the cover body 310a is displaced with respect to the base body 310b, the accommodation space of the main board case (not shown) is opened and closed.

  Similarly to the main board case 110 of the embodiment, the hinged door type board case 310 is also attached to the front frame 12 as a gaming machine main body. When the substrate case 310 is attached to the front frame 12, the bottom surface 310 d of the base body 310 b as the first surface faces the front frame 12.

  FIG. 9 is a diagram illustrating an example of the obstacle 311 in the hinged door type substrate case 310.

  As shown in the drawing, the bottom surface 310d of the base body 310b as the first surface faces the front frame side mounting surface 115b of the front frame 12 as the second surface, as in the embodiment.

  The RF tag 112 is disposed between the bottom surface 310d of the base body 310b as the first surface and the front frame side mounting surface 115b of the front frame 12 as the second surface. One surface of the RF tag 112 is fixed to the bottom surface 310d of the base body 310b as the first surface. The other surface of the RF tag 112 is fixed to the bottom surface 310d of the base body 310b.

  The obstacle 311 is a wall fixed to the front frame 12. The obstacle 311 contacts the cover body 310a in a direction in which the cover body 310a is rotated when the accommodation space of the board case 310 is released in a state where the board case 310 is attached to the front frame 12 as the gaming machine body. Has a site. The obstacle 311 regulates the displacement of the cover body 310a with respect to the base body 310b by the portion that comes into contact with the cover body 310a.

  With such an obstacle 311, the accommodation space of the substrate case 310 cannot be opened with the substrate case 310 attached to the front frame 12. In order to perform an illegal act on the substrate accommodated in the substrate case 310, it is necessary to move the bottom surface 310d of the base body 310b from the front frame side attachment surface 115b.

  As described above, each surface of the RF tag 112 is fixed to the bottom surface 310d of the base body 310b and the bottom surface 310d of the base body 310b. When the substrate case 310 is moved to open the accommodation space of the substrate case 310, a force is applied to the RF tag 112. As a result, the RF tag is destroyed and communication with the reader becomes impossible.

  Thus, when an illegal act is performed on the substrate accommodated in the substrate case 310, the RF tag 112 is destroyed and a trace of the illegal act remains. Whether or not the RF tag 112 has been destroyed can be easily determined by the reaction of the reader 210. Therefore, also in such a modification, fraudulent acts can be easily detected as in the embodiment.

  The present invention can be applied to a gaming machine including an openable / closable board case.
