Description

  The present invention relates to a board case for a gaming machine that can detect unauthorized opening by using a wireless communication device.

  A gaming machine such as a pachinko machine includes various control boards on which a CPU, a ROM, and the like are mounted. Generally, the control board is accommodated in a board case composed of a case main body and a case lid, and a seal seal is attached to the case main body and the case lid so as to straddle them. Such a seal seal is for leaving a trace of the seal being peeled off when the case lid is opened, and the ROM on the control board is illegal by leaving such a visually distinguishable trace. It plays the role of suggesting the possibility of replacement with ROM (so-called back ROM). However, recently, a technique for unlawful acts has been developed, such as a method of opening the substrate case with almost no trace of peeling of the seal seal. For this reason, a seal seal using a small chip-like wireless communication device capable of wirelessly communicating security data has been proposed.

  For example, Patent Document 1 discloses an RFID (Radio Frequency Identification) seal that is a kind of a seal seal using a small chip-shaped wireless communication device. The RFID seal includes a seal film (61) having an adhesive surface on one surface, and a wireless communication device including an IC chip (63) and an antenna (64), and at least the antenna of the wireless communication device is attached to the adhesive surface of the seal film. It is comprised in the state made to stick to. Then, in the state where the RFID seal is attached to the outer surface of the substrate case, if the wireless data communication can be normally performed between the RFID seal and the RFID inspection machine, the substrate case is not opened. judge. On the other hand, when wireless data communication cannot be normally performed between the RFID seal and the RFID inspection machine, the antenna attached to the seal film when the substrate case is opened (that is, the RFID seal is peeled off). It is determined that there is a high possibility that the substrate case has been damaged, and that there is a high possibility that the substrate case has been opened illegally. In this way, by using a small chip-like wireless communication device, it is possible to detect unauthorized opening of the substrate case more quickly and more reliably than in the past, which relied on the visual confirmation of the peeling trace of the seal seal.

JP 2000-334154 A

  However, as long as the RFID seal is attached to the outer surface side of the substrate case as in the conventional example, the IC chip can be easily contacted from the outside of the substrate case. For this reason, there is a possibility that the IC chip may be tampered with and damaged, or the IC chip may be damaged due to an unexpected event when the substrate case is transported. In addition, since there is a technique for cleverly removing the seal sticker in a state where it can be reattached using a medicine or the like, the RFID sticker is peeled off without damaging the antenna of the wireless communication apparatus according to such a technique. There is a possibility that the case can be opened illegally.

  In order to avoid such an inconvenience, there is no solution to affix the RFID seal to the inner surface side of the substrate case (that is, the inside of the case), but the RFID seal is attached to the case body on the inner surface side of the substrate case. Affixing at the boundary with the case lid itself is an extremely difficult task, and is not feasible at the manufacturing site.

  An object of the present invention is a board case for a gaming machine using a wireless communication device capable of performing wireless data communication with an external inspection device, and the wireless communication device or its device unless the substrate case is opened. An object of the present invention is to provide a gaming machine substrate case that is difficult to contact from the outside with respect to a wireless communication unit as a main part.

  The invention according to claim 1 is a case main body for storing an electronic circuit board for a gaming machine, and a case lid attached to the case main body so as to be capable of reciprocating between a closed position and an open position. A wireless communication device having an antenna surface provided with a communication antenna and capable of performing wireless data communication with an external inspection device, one of the case body and the case lid The body is provided with a holding portion for holding the wireless communication device inside the case body, and the other case body of the case body and the case lid body has the case lid body in the closed position. A facing portion that faces the wireless communication device held by the holding portion of the one case body when provided is disposed, and when the case lid is disposed at the closed position, the wireless communication device is configured to have its antenna. Front It is fixed to the holding part of the one case body in a state of facing the facing part of the other case body, and the communication antenna is placed between the antenna surface of the wireless communication device and the facing part. It is a board case for gaming machines characterized in that an adhesive for adhering is provided on the side of the part.

  In this gaming machine substrate case, a holding portion for holding the wireless communication device is provided inside one case body of the case main body and the case lid, and the wireless communication device is provided with the holding portion of the one case body. It is fixed to. Therefore, in a sealed state where the case lid is attached to the case body, the case lid is disposed at the closed position, and the substrate case is closed, the wireless communication device is confined inside the substrate case. That is, unless the substrate case is opened, it is impossible to physically contact the wireless communication device from the outside. Therefore, as long as the sealed state of the substrate case is maintained, it is possible to prevent the wireless communication device from being unintentionally damaged due to mischief or an accident during transportation.

  Further, the communication antenna provided on the antenna surface of the wireless communication device is placed between the antenna surface of the wireless communication device fixed to the holding portion of one case body and the facing portion of the other case body. An adhesive for adhering to the side is interposed. Therefore, the case lid is moved from the closed position toward the opening position in order to illegally open the substrate case in the sealed state, and there is relative movement between the wireless communication device on one case body side and the opposing portion on the other case body side. When this occurs, the communication antenna adhered to the facing portion side by the adhesive is peeled off from the wireless communication device and broken (for example, broken). A wireless communication device with a damaged communication antenna cannot normally perform wireless data communication with an external inspection device. Therefore, the external inspection device detects that the wireless data communication is abnormal and the board case is illegally opened. Discovered facts (or the possibility of tampering).

  According to a second aspect of the present invention, there is provided a case main body for storing an electronic circuit board for a gaming machine, and a case lid attached to the case main body so as to be capable of reciprocating between a closed position and an opening position. A wireless communication device having an antenna surface provided with a communication antenna and capable of performing wireless data communication with an external inspection device, one of the case body and the case lid The body is provided with a holding portion for holding the wireless communication device inside the case body, and the other case body of the case body and the case lid body has the case lid body in the closed position. A facing portion that faces the wireless communication device held by the holding portion of the one case body when provided is disposed, and when the case lid is disposed at the closed position, the wireless communication device is configured to have its antenna. Front The communication antenna is fixed to the facing portion of the other case body while facing the holding portion of one case body, and the communication antenna is held between the antenna surface of the wireless communication device and the holding portion. It is a board case for gaming machines characterized in that an adhesive for adhering is provided on the side of the part.

  In this gaming machine substrate case, a holding portion is provided inside one case body of the case main body and the case lid body, and the other case body of the case main body and the case lid body includes the holding portion. The wireless communication device held by the mobile phone is provided with a facing portion facing the wireless communication device, and the wireless communication device is fixed to the facing portion of the other case body. Therefore, in a sealed state where the case lid is attached to the case body, the case lid is disposed at the closed position, and the substrate case is closed, the wireless communication device is confined inside the substrate case. That is, unless the substrate case is opened, it is impossible to physically contact the wireless communication device from the outside. Therefore, as long as the sealed state of the substrate case is maintained, it is possible to prevent the wireless communication device from being unintentionally damaged due to mischief or an accident during transportation.

  In addition, a communication antenna provided on the antenna surface of the wireless communication device is provided between the antenna surface of the wireless communication device fixed to the opposite portion of the other case body and the holding portion of the one case body. An adhesive for adhering to the side is interposed. Therefore, the case lid is moved from the closed position toward the unsealed position in order to tamper open the sealed substrate case, and there is relative movement between the wireless communication device on the other case body side and the holding part on the one case body side. When this occurs, the communication antenna adhered to the holding portion side by the adhesive is peeled off from the wireless communication device and broken (for example, broken). A wireless communication device with a damaged communication antenna cannot normally perform wireless data communication with an external inspection device. Therefore, the external inspection device detects that the wireless data communication is abnormal and the board case is illegally opened. Discovered facts (or the possibility of tampering).

  According to a third aspect of the present invention, there is provided a case main body for storing an electronic circuit board for a gaming machine, and a case lid attached to the case main body so as to be capable of reciprocating between a closed position and an open position. A wireless communication unit having an antenna surface provided with a communication antenna and capable of performing wireless data communication with an external inspection apparatus, and a support unit integrated with the wireless communication unit A wireless communication device, and one of the case lid and the case body has a support hole through which a support portion of the wireless communication device can be inserted, and closes the case lid. When arranged in a position, the wireless communication portion of the wireless communication unit faces the other case body of the case lid body and the case body so that the antenna surface of the wireless communication device faces the wireless support hole of the one case body. The communication device support is fitted An adhesive for adhering the communication antenna to the other case body is interposed between the antenna surface of the wireless communication unit of the wireless communication device and the other case body. This is a board case for a gaming machine.

  In this gaming machine substrate case, one case body of the case lid body and the case main body is formed with a support hole for a support portion of the wireless communication device, and the other of the case lid body and the case main body. With the case body facing the antenna surface of the wireless communication unit of the wireless communication device, the support portion of the wireless communication device is fitted and supported in the support hole of the one case body. That is, in a sealed state in which the case lid is attached to the case body, the case lid is disposed at the closed position, and the substrate case is closed, the wireless communication unit of the wireless communication device includes the case body and the case lid. It is confined inside the substrate case at or near the boundary region. That is, unless the substrate case is opened, it is impossible to physically contact the wireless communication unit of the wireless communication device from the outside. Therefore, as long as the sealed state of the substrate case is maintained, it is possible to prevent a situation where the wireless communication unit of the wireless communication device is unintentionally damaged due to mischief or an accident during transportation.

  Further, between the radio communication unit antenna surface of the radio communication device supported by one case body and the other case body, a communication antenna provided on the radio communication unit antenna surface is arranged on the side of the other case body. An adhesive for adhering to the substrate is interposed. Therefore, when the case lid is moved from the closed position toward the opening position in order to illegally open the substrate case in the sealed state, a relative movement occurs between the wireless communication device on one case body side and the other case body. Along with this, the communication antenna adhered to the other case body by the adhesive is peeled off from the wireless communication unit and broken (for example, disconnected). Since the wireless communication unit with a damaged communication antenna cannot normally perform wireless data communication with an external inspection device, the external inspection device detects that the wireless data communication is abnormal and the substrate case is illegally opened. Discovered facts (or the possibility of tampering).

  Hereinafter, some embodiments of the present invention will be described with reference to the drawings.

[First Embodiment]
1 to 5 show a gaming machine board case of the first embodiment. As shown in FIG. 1 to FIG. 3, the board case of the first embodiment is a case body 10 having a rectangular shape for housing an electronic circuit board (for example, a main control board or a payout control board) for gaming machines. (Also referred to as “base”) and a planar rectangular case lid 20 (also referred to as “cover”) that is slidably mounted on the case main body 10. The case body 10 and the case lid 20 are made of a synthetic resin such as polycarbonate.

  The case body 10 is formed in a planar rectangular box shape having a predetermined height or thickness. That is, the case body 10 includes a bottom wall portion 11 having a rectangular plane shape and four peripheral wall portions 12 and 13 formed in a bank shape along four sides (a pair of short sides and a pair of long sides) of the bottom wall portion 11. And have. A storage chamber 14 for an electronic circuit board is defined in an inner region surrounded by the four peripheral wall portions 12 and 13. Since the storage chamber 14 remains open upward in the case body 10 alone, the case lid 20 is used in combination as a member for closing the storage chamber 14 and sealing the storage chamber 14. The case lid 20 is slidable between a closed position (the position shown in FIGS. 1 and 2) for closing the storage chamber 14 and an opening position (for example, the position shown in FIG. 3) for opening the storage chamber 14. It has become. A known locking mechanism 15 for locking the case lid 20 disposed at the closed position to the case body 10 is provided on one of the peripheral wall portions 12 along both short sides of the case body 10. . Examples of the lock mechanism 15 include a lock mechanism 15 having a one-way pin or the like.

  As shown in FIG. 4A, on the outer surface of each peripheral wall 13 along both long sides of the case body 10, a rail extending in the longitudinal direction of each peripheral wall 13 (that is, the sliding direction of the case lid 20). Each groove 16 is formed. As shown in FIGS. 3 and 4, a flat rectangular rectangular tag housing recess is formed on the upper surface 13 a of one of the long side peripheral walls 13 of the case body 10 (the peripheral wall 13 shown on the left side in FIG. 3). 18 is formed so as to open or be exposed upward. The tag housing recess 18 is a holding unit for housing and holding the wireless communication tag 30 described later, and substantially corresponds to the planar shape corresponding to the planar shape of the wireless communication tag 30 and the thickness of the wireless communication tag 30. With depth.

  As shown in FIGS. 1 and 2, the case lid 20 is formed in a planar rectangular shape that is substantially similar to the case main body 10, and has four peripheral walls corresponding to the four peripheral wall portions 12, 13 of the case main body 10. Part (the peripheral wall 21 on the long side of the case lid is shown in FIGS. 3 and 4). The four peripheral walls of the case lid 20 also define the electronic circuit board storage chamber 14.

  As shown in FIGS. 4B and 4C, each peripheral wall 21 is provided at the lower end edge (or the outer end edge of the lower surface) of the outer peripheral surface of each peripheral wall 21 along both long sides of the case lid 20. Guide rails 22 each having an L-shaped cross section extending in the longitudinal direction (that is, the sliding direction of the case lid 20) are provided. When the case lid 20 is mounted on the case main body 10, the guide rails 22 of the case lid 20 engage with the rail grooves 16 of the case main body 10, whereby the upper surface of the long-side peripheral wall portion 13 of the case main body 10. While maintaining the state where the lower surface 21a of the long side peripheral wall portion 21 of the case lid 20 is in sliding contact with 13a (that is, the case main body 10 and the case lid 20 cannot be separated in the vertical direction), the case lid 20 is attached to the case body 10 so as to be slidable in the horizontal direction. The upper surface 13a of the long-side peripheral wall portion 13 of the case body 10 and the lower surface 21a of the long-side peripheral wall portion 21 of the case lid 20 are “the boundary surface or boundary region between the case bodies 10 and 20 when the lid is mounted”. It corresponds to.

  However, as shown in FIGS. 4B and 4C, the lower surface side of the long side peripheral wall portion 21 of the case lid 20 corresponding to the long side peripheral wall portion 13 of the case body 10 having the tag receiving recess 18. Is formed with a second lower surface (retracted lower surface 21b) that is retracted to a position several millimeters higher than the lower surface 21a. For this reason, when the case lid 20 is attached to the case body 10, the upper surface 13a of the long side peripheral wall 13 of the case main body 10 having the tag receiving recess 18 and the long side peripheral wall of the case lid 20 facing it. A gap S is secured between the receding lower surface 21 b of the part 21. The formation range of the gap S (see FIG. 1) covers a range from the end of the long side peripheral wall 13 to the lock mechanism 15 side to the position of the tag receiving recess 18 (that is, the position of the wireless communication tag 30).

  As shown in FIGS. 2 to 4, a support hole 23 is provided in the long side peripheral wall 21 of the case lid 20 corresponding to the long side peripheral wall 13 of the case body 10 having the tag receiving recess 18. It is formed so as to penetrate the portion 21 in the vertical direction. The support hole 23 is positioned so as to be directly above the tag receiving recess 18 of the case body 10 and to face the recess 18 when the case lid 20 is disposed at the closed position. Further, the support hole 23 has a planar rectangular shape substantially similar to the planar shape of the tag receiving recess 18, and the planar rectangular shape of the support hole 23 is slightly larger than the planar rectangular shape of the tag receiving recess 18. Therefore, the support hole 23 can pass through the wireless communication tag 30 to be accommodated in the tag accommodating recess 18. The support hole 23 is a hole for supporting a tag fixing member 24 described later on the inside thereof.

  As shown in FIGS. 2 and 4C, the tag fixing member 24 is fitted and supported in the support hole 23 of the case lid 20. The tag fixing member 24 is formed as a substantially rectangular parallelepiped block corresponding to the hole shape of the support hole 23, and completely fills the support hole 23 when fitted into the support hole 23. Further, since the tag fixing member 24 is fitted or pressed into the support hole 23 in a very tight manner and is practically integrated into the case lid 20, it is extremely difficult to pull out the tag fixing member 24 once it is inserted into the support hole 23. . In the first embodiment, the tag fixing member 24 fitted and supported in the support hole 23 of the case lid 20 is “the holding portion (tag housing of the case main body 10 when the case lid 20 is placed in the closed position”). It corresponds to “a facing portion facing the wireless communication tag 30 held in the recess 18)”.

  5A and 5B show a wireless communication tag 30 as a wireless communication device housed and held in the tag housing recess 18 of the case body 10. The wireless communication tag 30 includes a tag main body 31, an RFID chip 32 supported by the tag main body 31, and a communication antenna 33. The tag main body 31 is formed as a thin plate made of synthetic resin having a planar rectangular shape (for example, a rectangular shape of 2 cm × 1 cm). An ultra-small RFID chip 32 with a built-in communication processing circuit is embedded inside the tag body 31, and a thin line-like shape electrically connected to the RFID chip 32 is formed on one surface of the tag body 31. The communication antenna 33 is arranged in a meandering state.

  The RFID chip 32 with the communication antenna 33 can perform data communication with an external RFID inspection machine (not shown) using radio waves of a predetermined frequency. Specifically, when the communication antenna 33 catches a radio wave (access data signal) transmitted by an external RFID inspection machine and is transmitted to the RFID chip 32, the RFID chip 32 generates power based on the received wave. At the same time, it is determined whether or not the access data signal is genuine. If it is a legitimate access data signal from the RFID inspection machine, a predetermined radio wave (response data signal) is transmitted based on the security data held in advance by the chip 32. When the RFID inspection machine receives the radio wave transmitted by the wireless communication tag 30, the data communication between the RFID chip 32 and the RFID inspection machine is completed. The RFID inspection machine analyzes whether or not the data communication with the wireless communication tag 30 has been normally performed by analyzing whether or not the response data signal transmitted from the wireless communication tag 30 is based on legitimate security data. Determine whether. As long as data communication between the RFID inspection machine and the wireless communication tag 30 is normally performed, it is determined that there is no abnormality in the wireless communication tag 30 (and thus the substrate case).

  Further, as shown in FIG. 5B, a first adhesive is applied to almost one surface of the tag main body 31 provided with the communication antenna 33 (hereinafter, this surface is referred to as “antenna surface”). Thus, the first adhesive layer 34 is formed. Further, the second adhesive layer 35 is formed by applying a second adhesive to almost the entire surface of the tag body 31 opposite to the antenna surface (hereinafter, this surface is referred to as “an opposite side fixing surface”). Is formed. The second pressure-sensitive adhesive that forms the second pressure-sensitive adhesive layer 35 is a pressure-sensitive adhesive having a stronger adhesive strength than the first pressure-sensitive adhesive that forms the first pressure-sensitive adhesive layer 34. Note that, as indicated by a two-dot chain line in FIG. 5B, when the wireless communication tag 30 is not used (or during single transaction), the outside of the first adhesive layer 34 and the outside of the second adhesive layer 35. Is preferably covered with release paper (or release films) 36 and 37 to prevent adhesion of foreign matters to the adhesive layers 34 and 35 and to prevent a decrease in adhesive force.

  In using the substrate case of the first embodiment, the procedure for sealing the substrate case in which the electronic circuit board (indicated by a two-dot chain line in FIG. 3) is stored in the storage chamber 14 of the case body 10 is described in the following two ways. (First sealing procedure and second sealing procedure).

  In the first sealing procedure, first, wireless communication is performed in the recess 18 while the opposite fixed surface of the radio communication tag 30 is bonded to the bottom surface of the tag receiving recess 18 of the case body 10 via the second adhesive layer 35. The tag 30 is accommodated and fixed. Then, the antenna surface becomes the upper surface of the wireless communication tag 30 and is exposed from the tag housing recess 18, and the linear portion of the communication antenna 33 meanderingly disposed on the antenna surface is orthogonal to the sliding direction of the case lid 20. Thus, the wireless communication tag 30 is arranged. Subsequently, the case lid 20 waiting at the opening position is horizontally slid toward the closing position. At that time, as described above, a gap S is secured between the upper surface 13a of the long-side peripheral wall portion 13 of the case body 10 and the receding lower surface 21b of the long-side peripheral wall portion 21 of the case lid 20. There is no concern that the antenna surface of the wireless communication tag 30 held by the case body 10 will be rubbed by the lower surface of the case lid 20 that slides horizontally. By sliding the case lid 20 to the end in the closing direction and positioning the case lid 20 at the closing position, the wireless communication tag 30 held in the tag receiving recess 18 of the case main body 10 and the support hole 23 of the case lid 20. And the antenna surface of the wireless communication tag 30 is exposed through the support hole 23. Therefore, as shown in FIG. 4C, the tag fixing member 24 is fitted into the support hole 23, and the lower end surface (tip surface) thereof is adhered to the antenna surface of the wireless communication tag 30 through the first adhesive layer 34. Let By locking the case main body 10 and the case lid 20 with the lock mechanism 15, the sealing of the substrate case is almost completed.

  In the second sealing procedure, first, the case lid 20 waiting at the opening position is horizontally slid toward the closing position. By sliding the case lid 20 to the end in the closing direction and positioning the case lid 20 at the closing position, the tag receiving recess 18 of the case main body 10 and the support hole 23 of the case lid 20 coincide with each other. The tag receiving recess 18 is exposed through. Subsequently, the antenna surface of the wireless communication tag 30 is adhered in advance to the lower end surface (tip surface) of the tag fixing member 24 via the first adhesive layer 34, and the tag fixing member 24 in this state is attached to the case lid 20. Is inserted into the support hole 23. And as shown in FIG.4 (C), adhering the opposite side fixed surface of the radio | wireless communication tag 30 adhering to the lower end of the tag fixing member 24 to the bottom face of the tag accommodation recessed part 18 via the 2nd adhesion layer 35, The wireless communication tag 30 is accommodated and fixed in the recess 18. At this time, the wireless communication tag 30 is disposed so that the linear portion of the communication antenna 33 meanderingly disposed on the antenna surface is orthogonal to the sliding direction of the case lid 20. By locking the case main body 10 and the case lid 20 with the lock mechanism 15, the sealing of the substrate case is almost completed.

  An intact (that is, original) wireless communication tag 30 is housed in the board case that has been properly sealed through the first or second sealing procedure, so that the radio wave (access data) from the RFID inspection machine Normal radio wave (response data signal) can be transmitted in response to the signal. As described above, as long as normal data communication can be performed between the RFID inspection machine and the wireless communication tag 30 in the substrate case, it is determined that the substrate case is not tampered with.

  It is assumed that the lock mechanism 15 is unlocked and the substrate case is illegally opened. In that case, the case lid 20 is forcibly slid from the closed position to the opened position by an unauthorized person. However, even in that case, the wireless communication tag 30 is firmly bonded and fixed to the tag housing recess 18 by the second adhesive layer 35 and the wireless communication is performed based on the engagement between the tag housing recess 18 and the wireless communication tag 30. Since the horizontal slide of the tag 30 is originally restricted, the main body 31 of the wireless communication tag 30 is continuously held in the tag receiving recess 18 of the case main body 10. In contrast, the adhesive force of the first adhesive layer 34 interposed between the tag fixing member 24 and the wireless communication tag 30 may be weaker than the adhesive force of the second adhesive layer 35. Although the adhesive relationship with the tag fixing member 24 is eliminated during relative sliding, a part of the communication antenna 33 provided on the antenna surface of the wireless communication tag 30 is still below the tag fixing member 24 that slides with the case lid 20. It adheres to the end face and follows the movement of the tag fixing member 24. For this reason, a tension arises between a part of the communication antenna 33 adhered to the tag fixing member 24 (opposing part of the case lid 20) moving in the opening direction and the tag main body 31 staying on the case main body 10 side. As a result, a part of the communication antenna 33 is peeled off from the tag main body 31, and the communication antenna 33 on the tag main body 31 side is disconnected at one place or a plurality of places.

  Even if the fraudster opens the substrate case, the case lid 20 is closed again, and even if it is attempted to disguise so that no trace of unauthorized opening remains at first glance, the inside of the re-sealed substrate case The communication antenna 33 of the wireless communication tag 30 remains disconnected. Therefore, when inspected by an RFID inspection machine after tampering, the damaged wireless communication tag 30 cannot respond to the radio wave (access data signal) from the RFID inspection machine at all or is normal even if it can respond. (Response data signal) cannot be transmitted. When the RFID inspection machine detects this data communication abnormality, it can be easily found that the board case has been tampered with.

  Thus, according to this embodiment, when the substrate case is tampered with, the communication antenna 33 of the wireless communication tag 30 housed in the substrate case is disconnected, and as a result, the wireless communication tag 30 and the RFID inspection machine Since normal wireless data communication is not possible, the fact of unauthorized opening can be found quickly and reliably without visually checking the state of the seal. Further, according to the substrate case of the present embodiment, in the sealed state where the case lid 20 is disposed at the closed position and the substrate case is closed, the wireless communication tag 30 is confined inside the substrate case. Unless it is opened, the wireless communication tag 30 cannot be physically contacted from the outside. Therefore, as long as the sealed state of the substrate case is maintained, it is possible to prevent the wireless communication tag 30 from being unintentionally damaged due to mischief or an accident during transportation.

  In the substrate case of the first embodiment, after sealing, only the tag fixing member 24 is extracted from the case lid 20 at the closed position, and the injustice acts on the inside of the substrate case from the support hole 23 that becomes the extraction mark. It cannot be said that there is no act. However, since the tag fixing member 24 is tightly fitted (press-fitted) into the support hole 23, it is very difficult to remove the tag fixing member 24 from the support hole 23 itself. Even if the tag fixing member 24 is successfully extracted from the support hole 23, it is avoided that a part of the communication antenna 33 is peeled off from the antenna surface of the wireless communication tag 30 during the extraction process and the communication antenna 33 is disconnected. I can't. Therefore, even when the tag fixing member 24 is forcibly extracted from the support hole 23, the fact of such unauthorized extraction can be found by the RFID inspection machine.

[Modification of First Embodiment]
In the first embodiment, the tag fixing member 24 fitted into the support hole 23 of the case lid 20 is provided as a separate member separated from the case lid 20. Then, in the process of fitting the tag fixing member 24 into the support hole 23, the lower surface of the tag fixing member 24 faces the upper surface of the wireless communication tag 30, and the lower surface of the tag fixing member 24 is interposed via the first adhesive layer 34. When the wireless communication tag 30 adheres to the upper surface (antenna surface), the tag fixing member 24 completely fills the support hole 23 and is integrated with the case lid 20, resulting in a “facing portion”. did. Instead of this, a configuration as shown in FIGS. 6A and 6B may be employed. Specifically, the portion of the case lid 20 that is occupied by the support hole 23 or the tag fixing member 24 in the first embodiment (that is, when the case lid 20 is placed in the closed position, The facing portion facing the wireless communication tag 30 held in the recess 18 may be a plastic portion 25 made of a plastically deformable material. The plastic part 25 is a part integrated with the case main body 20 from the beginning (that is, a part of the case main body 20), and differs from the other parts of the case lid 20 only in the constituent material or the flexibility.

  According to the modified example of FIG. 6, the sealing of the substrate case can be completed by a procedure that substantially conforms to the first sealing procedure described in the first embodiment. However, it differs slightly from the first sealing procedure in the following two points. The first difference is that the case lid 20 is slid to the end in the closing direction to position the case lid 20 at the closing position, so that the wireless communication tag 30 held in the tag receiving recess 18 of the case body 10 and the case It is a point which opposes the plastic part 25 of the cover body 20 (refer FIG. 6 (A)). The second difference is that the bottom surface of the plastic part 25 is deformed by pressing the upper part of the plastic part 25 with a finger or the like and plastically deforming the plastic part 25 so as to dent downward after completion of the opposing arrangement in FIG. Is adhered to the antenna surface of the wireless communication tag 30 through the first adhesive layer 34 (see FIG. 6B). After the sealing of the substrate case is completed through the procedures of FIGS. 6A and 6B, the modified example of FIG. 6 also has the same operations and effects as the first embodiment. That is, the plastic part 25 integrated with the case lid 20 from the beginning and the tag fixing member 24 later integrated with the case lid 20 can be said to be functionally equivalent. It can be positioned as “a facing portion facing the wireless communication tag 30 held in the tag receiving recess 18”.

  In the first embodiment and the modified example of FIG. 6, the case main body 10 is provided with a tag receiving recess 18 as a holding portion, and the antenna surface of the wireless communication tag 30 is placed on the facing portion (the tag fixing member 24, The tag 30 is fixed to the recess 18 while the opposite fixing surface of the wireless communication tag 30 is adhered to the bottom surface of the tag receiving recess 18 by the second adhesive layer 35 in a state of facing the plastic portion 25). The first adhesive layer for adhering the communication antenna 33 to the facing portion side between the antenna surface of the wireless communication tag 30 and the facing portion of the case lid 20 (tag fixing member 24, plastic portion 25). 34, the antenna surface and the facing portion were loosely bonded. Instead of this, an alternative configuration corresponding to a case where the upper and lower surfaces of the wireless communication tag 30 are reversed may be adopted. That is, without providing the tag receiving recess 18 in the case body 10, a part of the flat upper surface 13 a of the long side peripheral wall portion 13 of the case body 10 is positioned as a “holding portion” and the case lid 20 is closed. It is assumed that the facing portions (the tag fixing member 24 and the plastic portion 25) of the case lid 20 face the holding portion (a part of the peripheral wall upper surface 13a) of the case main body 10 when arranged in the case. Then, with the antenna surface of the wireless communication tag 30 facing the holding portion (a part of the peripheral wall upper surface 13a) of the case body 10, the opposite fixing surface of the wireless communication tag 30 is covered by the second adhesive layer 35. The lid 20 is bonded and fixed to the facing portion (tag fixing member 24, plastic portion 25). Further, a first adhesive layer 34 for adhering the communication antenna 33 to the holding portion side is provided between the antenna surface of the wireless communication tag 30 and the holding portion of the case body 10 (a part of the upper surface 13a of the peripheral wall portion). By interposing, the antenna surface and the holding portion are loosely bonded.

  Even when such an alternative configuration is employed, the same operational effects as the first embodiment and the modified example of FIG. This is because the adhesive force of the second adhesive layer 35 attached to the opposite fixed surface is stronger than the adhesive force of the first adhesive layer 34 attached to the antenna surface of the wireless communication tag 30. Even when a relative movement occurs between the case main body 10 (and the holding portion) and the case lid 20 (and the facing portion) by opening, the wireless communication tag 30 is located on the facing portion (24, 25) side of the case lid 20. To be held fixed. Then, based on the adhesive force of the first adhesive layer 34, the disconnection of the antenna is ensured between the part of the communication antenna 33 that is to remain in the holding part of the case body 10 and the tag body 31 that follows the opposing part. It is because it occurs.

  In the first embodiment and the modified example of FIG. 6, the case main body 10 is provided with a holding portion (tag receiving recess 18 and the like), and the case lid 20 is provided with a facing portion (tag fixing member 24 and plastic portion 25). A configuration in which the relationship between the case main body 10 and the case lid 20 is reversed may be employed. In other words, a holding portion (such as the tag receiving recess 18) may be provided on the case lid 20 side, and an opposing portion (the tag fixing member 24, the plastic portion 25) may be provided on the case body 10 side. Even in the case of this reverse rotation configuration, when the case lid 20 is horizontally slid, relative movement occurs between the holding portion of one case body of the case body 10 and the case lid body 20 and the opposing portion of the other case body. In that respect, there is no difference from the first embodiment and the modified example of FIG. 6, and therefore the same operational effects can be achieved.

[Second Embodiment]
7 and 8 show a gaming machine board case of the second embodiment. In the first embodiment, the tag fixing member 24 is fitted and fixed in the support hole 23 of the case lid 20, but in the second embodiment, the wireless communication device 40 is directly fitted in the support hole 23 of the case lid 20. Type board case. Note that the case lid 20 constituting the substrate case of the second embodiment is exactly the same as the case lid 20 of the first embodiment. The case body 10 constituting the substrate case of the second embodiment is substantially the same as the case body 10 of the first embodiment, but is different from the case body 10 of the first embodiment only in that it does not have the tag receiving recess 18. Is different.

  As shown in FIGS. 7 and 8, the wireless communication device 40 used in the second embodiment includes a support portion 41 and a wireless communication portion 42, and is a substantially rectangular parallelepiped block body in which both portions 41 and 42 are integrated. It is configured as. The support part 41 of the wireless communication device 40 is formed in a substantially rectangular parallelepiped shape corresponding to the hole shape of the support hole 23 of the case lid 20, and the support part 41 is press-fitted into the support hole 23 of the case lid 20. Thus, the wireless communication device 40 is fixed to the case lid 20.

  The wireless communication unit 42 of the wireless communication device 40 is provided at the lower end of the support unit 41. The wireless communication unit 42 is a part for performing wireless data communication with an external RFID inspection machine, and corresponds to the wireless communication tag 30 in the first embodiment. That is, an ultra-small RFID chip 32 with a built-in communication processing circuit is embedded in the wireless communication unit 42. A thin wire-shaped communication antenna 33 electrically connected to the RFID chip 32 is disposed in a meandering manner on the lower surface of the wireless communication unit 42, and the lower surface of the wireless communication unit 42 serves as an antenna surface. An adhesive layer 43 is formed on the antenna surface by applying an adhesive 43. As shown by a two-dot chain line in FIG. 8, when the wireless communication device 40 is not used (or at the time of single transaction), the outside of the adhesive layer 43 is covered with a release paper (or release film) 44, thereby providing an adhesive. It is preferable to prevent foreign matter from adhering to the layer 43 and to prevent a decrease in adhesive force.

  When using the substrate case of the second embodiment, first, the case lid 20 that has been waiting at the opening position is horizontally slid in the closing direction, and the case lid 20 is positioned at the closing position. Subsequently, as shown in FIG. 7, the wireless communication device 40 is inserted into the support hole 23 of the case lid 20, and the lower surface (wireless) of the wireless communication device 40 is placed on the upper surface 13 a of the long-side peripheral wall portion 13 of the case body 10. The antenna surface of the communication unit 42 is adhered via the adhesive layer 43. Then, the case body 10 and the case lid 20 are locked by the lock mechanism 15 to complete the sealing of the substrate case.

  According to the substrate case of the second embodiment, normal data communication can be performed between the RFID inspection machine and the wireless communication unit 42 in the substrate case as long as the substrate case is not tampered with. On the other hand, when the fraudster unsuccessfully opens the board case and the case lid 20 is forcibly slid from the closed position to the opened position, the communication antenna 33 is disconnected, and the RFID inspection machine and the radio in the board case are disconnected. Normal data communication with the communication unit 42 cannot be performed. More specifically, when the case lid 20 slides in the opening direction, a part of the communication antenna 33 provided on the antenna surface of the wireless communication unit 42 continues to adhere and remain on the peripheral wall upper surface 13a of the case body 10. On the other hand, since the entire wireless communication device 40 including the wireless communication unit 42 moves relative to the case lid 20, a part of the communication antenna 33 is peeled off from the wireless communication unit 42, and the communication antenna of the wireless communication unit 42. 33 will be in the state where it was disconnected at one place or a plurality of places. Therefore, the substrate case of the second embodiment has the same operations and effects as the substrate case of the first embodiment.
