Description

  The present invention relates to a gaming machine board case for storing an electronic circuit board for gaming machines.

  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 to provide a gaming machine board case that covers a part in a closed position of the case lid so that a finger cannot be touched by both the case lid and the case body, and the case lid is opened from the closed position. It is intended to damage the parts when it is illegally moved.

  The board case for a gaming machine according to claim 1 is a case main body having a storage chamber for storing an electronic circuit board for a gaming machine, and a closed position that is provided in the case main body and closes the storage chamber of the case main body. And a case lid that is moved between opening positions that open the storage chamber of the case main body, and a finger is touched at a closed position of the case lid provided on one of the case main body and the case lid. A part that is covered with both the case body and the case lid so that it cannot be touched, and is opened so that a finger can be touched at the opening position of the case lid, and the case body and the case lid Provided on the other side of the body, when the case lid is moved from the closed position to the unsealed position, and moves relative to the component along a fixed relative movement path, A breakage tool for damaging the component is provided, and when the case lid is moved from the closed position to the opening position, the breaker comes into contact with the component when the breaker is in contact with the case. It is characterized in that it is disposed in the relative movement path of the breaker so as to be broken by the operating force of the lid.

  The board case for a gaming machine according to claim 2 is a case main body having a storage chamber for storing an electronic circuit board for a gaming machine, and a closed position provided in the case main body for closing the storage chamber of the case main body. And a case lid that is moved between opening positions that open the storage chamber of the case main body, and a finger is touched at a closed position of the case lid provided on one of the case main body and the case lid. A part that is covered with both the case body and the case lid so that it cannot be touched, and is opened so that a finger can be touched at the opening position of the case lid, and the case body and the case lid When the case lid provided on the other of the bodies is operated to move from the closed position to the opened position and when moved from the opened position to the closed position, respectively. It moves relative to the part in a fixed relative movement path, and includes a breakage tool for damaging the part, and the part is moved from the closed position toward the unsealed position. It is arranged in the relative movement path of the breakage tool so that the breakage tool comes into contact with each other when operated and when moved from the opening position toward the closing position. One of the tools is configured such that when the case lid is moved from the closed position toward the opening position, the broken tool comes into contact with the parts so that the parts are damaged by the operating force of the case lid. When the case lid is moved from the opened position to the closed position in the first state determined in advance, the case is prevented so that the component is not damaged even if the damaged tool contacts the component. Characterized in place is to retreat to a different second state from a first state in the operation force of the scan lid the first state.

  The gaming machine board case according to claim 3, wherein one of the component and the breakage tool is removed from the second state when one of the component and the breakage tool is retracted from the first state to the second state. It is characterized in that it is provided with a biasing means for biasing toward the first state.

  According to the gaming machine substrate case according to each of claims 1, 2, and 3, since the external contact with the component is impossible at the closed position of the case lid, the component is mischievous. It is possible to prevent unintentional damage due to accidents during transportation. When the case lid is illegally moved from the closed position to the unsealed position, the breakage tool comes into contact with the component, forcibly damaging the component.

  According to the gaming machine substrate case according to each of claims 2 and 3, when the case lid is moved from the opening position toward the closing position, the breakage tool is moved from the first state to the second state. Therefore, it is possible to prevent the damaged tool from damaging the part.

A board case for a gaming machine according to an embodiment of the present invention will be described with reference to FIGS.
As shown in FIGS. 1 to 3, the board case of the present embodiment has a case body 10 (planar rectangular shape) for accommodating an electronic circuit board (for example, a main control board or a payout control board) for a gaming machine. And a case lid 20 (also referred to as a “cover”) having a rectangular shape 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 movable 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. 4, rail grooves 16 extending in the longitudinal direction of each peripheral wall 13 (that is, the sliding direction of the case lid 20) are formed on the outer surface of each peripheral wall 13 along both long sides of the case body 10. Is formed. As shown in FIGS. 3 to 5, the longitudinal direction of the peripheral wall portion 13 is provided on the upper surface 13 a of one of the long side peripheral wall portions 13 of the case body 10 (the peripheral wall portion 13 shown on the left side in FIG. 3). A cutter moving groove 17 extending in the direction is formed. The cutter moving groove 17 serving as a breaker moving groove is positioned substantially at the center in the width direction of the peripheral wall portion 13 and has a groove width and a groove depth that can receive a cutter 43 serving as a broken tool described later with a margin. It is formed so as to open upward while having. Further, a tag receiving recess 18 having a flat rectangular shape is formed on the upper surface 13 a of the peripheral wall portion 13 having the cutter moving groove 17 in the middle of the cutter moving groove 17. The tag receiving recess 18 is opened or exposed on the upper surface side of the peripheral wall portion 13 and communicates with the cutter moving groove 17 located on the lower side thereof. The tag housing recess 18 is a recess for housing and holding a wireless communication tag 30 described later, and has a planar shape corresponding to the planar shape of the wireless communication tag 30 and a depth slightly larger than the thickness of the wireless communication tag 30. And have.

  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 5). The four peripheral walls of the case lid 20 also define the electronic circuit board storage chamber 14.

  As shown in FIG. 5, the lower end edge (or the outer end edge of the lower surface) of the outer peripheral surface of each peripheral wall 21 along the two long sides of the case cover 20 has a longitudinal direction (that is, a case cover) of each peripheral wall 21. A guide rail 22 having an L-shaped cross section extending in the sliding direction of the body 20 is provided. When the case lid 20 is attached to the case main body 10, the guide rail 22 of the case lid 20 engages with the rail groove 16 of the case main body 10, so that the upper surface 13 a of the long-side peripheral wall portion 13 of the case main body 10 is engaged. On the other hand, the case lid 20 maintains the state where the lower surface 21a of the long side peripheral wall 21 of the case lid 20 is always in sliding contact (that is, the case main body 10 and the case lid 20 cannot be separated in the vertical direction). Is attached to the case body 10 so as to be slidable in the horizontal direction. In this embodiment, the upper surface 13a of the long-side peripheral wall portion of the case body 10 or the lower surface 21a of the long-side peripheral wall portion 21 of the case lid 20 is the “boundary surface between the case bodies 10 and 20 when the lid is mounted”. Equivalent to.

  As shown in FIGS. 5 and 6, 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 cutter moving groove 17 opens to the lower surface 21 a side. Thus, the displacement mechanism accommodating recess 23 is formed. The displacement mechanism housing recess 23 is provided with a spring 41 (coil spring 41 is shown in FIG. 5) and a support plate 42 as urging means. Specifically, the upper end portion of the spring 41 is fixed to the ceiling wall 23 a of the displacement mechanism accommodating recess 23, and the support plate 42 is connected to the lower end portion of the spring 41. Further, a cutter 43 as a breakage tool is attached to the lower surface of the support plate 42. In this embodiment, the coil spring 41 is used as the urging means, but this urging means may be replaced with another spring such as a leaf spring or other elastic member.

  As a result of the support plate 42 and the cutter 43 being elastically supported by the spring 41 in the displacement mechanism accommodating recess 23, at least the cutter 43 is in the vertical direction (that is, the vertical direction intersecting substantially perpendicular to the horizontal sliding direction of the case lid 20). It is possible to move to. In the natural support state of the cutter 43 by the spring 41, the cutter 43 protrudes from the lower surface 21 a of the peripheral wall portion 21 toward the case body 10, and the tip end (lower end) of the cutter 43 enters the cutter moving groove 17. I have entered. Therefore, the cutter 43 can move horizontally along the cutter moving groove 17 along with the horizontal slide of the case lid 20.

  As shown in FIG. 6 (A), the cutter 43 of this embodiment is formed in a triangular shape in side view, the base (upper side) of the triangle is connected to the support plate 42, and the other two sides are ridges, respectively. 44 and blade portion 45. In this embodiment, the peak portion 44 of the cutter 43 is positioned on the front side in the forward direction of the cutter 43 when the case lid 20 is slid forward in the closing direction, and the blade of the cutter 43 is on the opposite side (the rear side in the forward direction). The cutter 43 is attached to the support plate 42 in such an orientation that the portion 45 is positioned. The peak portion 44 corresponding to the front portion of the cutter 43 is formed with an inclination angle (hereinafter referred to as “an inclination angle of relief in the closing direction slide”) such that the upper end portion thereof is located on the front side in the forward direction. For this reason, the peak portion 44 of the cutter 43 is not limited to the passive role of not functioning as a cutting blade, and retracts the cutter 43 in the vertical direction when contacting the wireless communication tag 30 held by the case body 10. It plays an active role of functioning as a guide part for this purpose (details will be described later). On the other hand, the blade portion 45 corresponding to the rear portion of the cutter 43 has an inclination angle (hereinafter referred to as “opening”) such that the lower end portion thereof is located on the front side in the backward direction of the cutter 43 when the case lid 20 is slid back in the opening direction. The angle of inclination of the directional slide ”). Note that the inclination angle of the peak portion 44 is a gentle inclination angle that is closer to the horizontal, whereas the inclination angle of the blade portion 45 is a steep inclination angle that is closer to the vertical. Further, by forming the most distal end (lowermost end) of the ridge 44 of the cutter 43 in an R shape, the sharpness of the cutter tip is eliminated.

  7A and 7B show a wireless communication tag 30 as a wireless communication device accommodated and held in the tag accommodating 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 body 31 is formed as a thin plate made of synthetic resin having a planar rectangular shape (for example, a 1 cm × 1 cm square shape). An ultra-small RFID chip 32 with a built-in communication processing circuit is embedded inside the tag main body 31, and a thin wire communication antenna electrically connected to the RFID chip 32 is placed on the upper surface of the tag main body 31. 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. More specifically, when the communication antenna 33 catches a radio wave (access data signal) transmitted from an external RFID inspection machine and is transmitted to the RFID chip 32, the RFID chip 32 self-generates based on the received wave. In addition, 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, data communication between the wireless communication tag 30 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).

Next, the usage method and advantages of the substrate case of this embodiment will be described.
At the start of use of the substrate case, as shown in FIG. 3, an electronic circuit board (indicated by a two-dot chain line) is stored in the storage chamber 14 of the case body 10, and the wireless communication tag 30 is stored in the tag storage recess 18 of the case body 10. To accommodate. For the tag housing recess 18, the wireless communication tag 30 is placed so that the linear portion of the communication antenna 33 meanderingly disposed on the wireless communication tag 30 is orthogonal to the cutter movement path (or the cutter movement groove 17). It is preferable to arrange. Thereafter, the case lid 20 waiting in the opening position is horizontally slid toward the closing position.

  As the case lid 20 slides horizontally in the closing direction, the cutter 43 moves horizontally in the cutter moving groove 17 along the cutter moving path. The front end portion (lower end portion) of the cutter 43 has entered deeply into the cutter moving groove 17, whereas the wireless communication tag 30 in the tag receiving recess 18 is located near the upper portion of the cutter moving groove 17. For this reason, it is inevitable that the cutter 43 contacts (interferes) with the wireless communication tag 30 during the movement of the cutter 43 (see FIGS. 5 and 6A). However, in the present embodiment, the front portion of the cutter 43 in the moving direction when sliding in the closing direction has a peak 44, and the peak 44 is given a gentle inclination, and the cutter 43 itself moves in the vertical direction. It is possible. Therefore, as the cutter 43 advances after the peak portion 44 of the cutter 43 contacts the wireless communication tag 30, the cutter 43 is retracted upward by the guide action of the inclined peak portion 44. Then, as shown in FIG. 6B, most of the cutter 43 is immersed in the displacement mechanism accommodating recess 23 of the case lid 20 against the biasing force of the spring 41, and the cutter 43 holds the wireless communication tag 30. Get over without cutting. At that time, the tip of the cutter 43 rubs the upper surface of the wireless communication tag 30, but the tip of the cutter 43 is formed in an R shape as described above. The communication antenna 33 is not disconnected.

  When the cutter 43 gets over the wireless communication tag 30, the urging force of the spring 41 causes the cutter 43 to return to the original position where the tip end portion enters deeply into the cutter moving groove 17. When the case lid 20 is slid to the end in the closing direction, the cutter 43 reaches the end of the cutter moving groove 17 and the case lid 20 is positioned at the closing position. Therefore, the case main body 10 and the case lid 20 are locked by the lock mechanism 15 so that the sealing of the substrate case is almost completed. An intact (that is, the original figure) wireless communication tag 30 is housed in the properly sealed board case, so that the normal radio wave (response data signal) is responded to the radio wave (access data signal) from the RFID inspection machine. Data signal) can be transmitted. 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. Then, as shown in FIG. 6C, the blade portion 45 of the cutter 43 that slides backward in the opening direction in the cutter moving groove 17 collides with the wireless communication tag 30, and along with the sliding of the case lid 20 in the opening direction. The cutter 43 cuts the wireless communication tag 30. In the case of FIG. 6C, unlike the cases of FIGS. 6A and 6B, the blade edge 45 of the cutter is given the “angle of inclination in the sliding in the opening direction” as described above. Therefore, the cutter 43 does not retreat upward into the displacement mechanism accommodating recess 23. Therefore, the wireless communication tag 30 is reliably cut by the cutter 43 that maintains the protruding state into the cutter moving groove 17. At least the communication antenna 33 of the wireless communication tag 30 is disconnected at a plurality of locations.

  Even after the fraudster has illegally opened the board case, the case lid 20 is closed again, and even if it is attempted to perform a disguise so that no trace of illegal opening remains at first glance, the inside of the re-sealed board case The wireless communication tag 30 remains broken. 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 wireless communication tag 30 housed in the substrate case is cut and broken by the cutter 43, and as a result, normal wireless communication with the RFID inspection machine is performed. By disabling data communication, it is possible to quickly and reliably find the fact of unauthorized opening without visually checking the status 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.

[Modification] A modification of the embodiment of the invention will be described below.
As shown in FIG. 8, a protective sheet 34 may be provided at one end of the tag main body 31 of the wireless communication tag 30. The protective sheet 34 is made of a film-like material having excellent scratch resistance, and has a shape and size that can cover the entire upper surface (antenna surface) of the tag body 31. When the cutter 43 slides horizontally in the closing direction, the end portion of the protective sheet 34 is fixed to the end portion side of the tag main body 31 with which the peak portion 44 of the cutter 43 first comes into contact. According to FIG. 8, even when the cutter 43 gets over the upper surface of the wireless communication tag 30 as the cutter 43 slides in the closing direction, the protective sheet 34 is interposed between the tag upper surface and the cutter 43. Since the upper surface of the tag is protected by this, damage to the communication antenna 33 is reliably prevented. On the other hand, the protection sheet 34 is lifted in the opening direction as indicated by the two-dot chain line in FIG. 43 does not hinder the disconnection of the wireless communication tag 30 by 43.

  As shown in FIGS. 9A and 9B, a plate-like sled 46 as a guide portion may be provided on the peak portion 44 of the cutter 43 fixed to the lower surface of the support plate 42. In this case, when the cutter 43 slides horizontally in the closing direction, the sled 46 gets over while rubbing the upper surface of the wireless communication tag 30. By providing the sled 46 at the front side portion of the cutter 43 in the forward direction, the contact area with the upper surface of the tag is increased as compared with the case of the peak portion 44, and the communication antenna 33 can be more reliably prevented from being damaged.

  Instead of the cutter 43, a cutting tool 47 using a piano wire 48 as shown in FIG. The piano wire cutting tool 47 in FIG. 10 includes a frame 49 having a substantially U-shaped side view and a piano wire 48 attached to the frame 49. The frame 49 is connected to the upper arm 51 fixed to the lower surface of the support plate 42, the lower arm 52 positioned below the upper arm 51, and the front ends of the upper and lower arms 51 and 52 positioned on the front side of the frame 49. Part 53. A piano wire 48 is stretched between the upper arm portion 51 and the lower arm portion 52 in a substantially vertical direction. Further, the connecting portion 53 constituting the front side portion of the frame 49 is formed with an inclination angle of the angle of sliding in the opening direction slide, like the peak portion 44 of the cutter 43, and functions as a guide portion. The piano wire cutting tool 47 of FIG. 10 is functionally equivalent to the cutter 43, and even when the cutting tool 47 is used instead of the cutter 43, the same operation and effect as in the above embodiment are achieved.

  In the above embodiment, the cutter 43 protrudes from the displacement mechanism accommodating recess 23 of the case lid 20, but a recess opening / closing lid (shown in the drawing) that can open and close the recess 23 as necessary near the entrance / exit of the displacement mechanism accommodating recess 23. (Omitted) may be attached. By providing the recess opening / closing lid, when the case lid 20 is not attached to the case main body 10, it is possible to close the recess opening / closing lid and enclose the cutter 43 in the recess 23. On the other hand, when the substrate case is assembled or used, the cutter 43 can function as described in the above embodiment by opening the recess opening / closing lid.

  In the above embodiment, the wireless communication tag 30 is fixedly held on the case body 10 side, and the cutter 43 is spring supported on the case lid 20 side so as to be vertically movable. However, the object of spring support may be replaced. For example, as shown in FIG. 11, the wireless communication tag 30 may be supported by a spring 41 so as to be vertically movable on the case body 10 side, and the cutter 43 may be fixedly held on the case lid 20 side. Even when the configuration as shown in FIG. 11 is adopted, the same operations and effects as the above embodiment can be obtained. That is, by sliding the case lid 20 in the closing direction, the substrate case can be sealed without damaging the wireless communication tag 30, and when the case lid 20 is tampered with, the case lid 20 is slid in the opening direction. The wireless communication tag 30 can be disconnected by 43.

  Instead of the cutting tool such as the cutter 43 and the piano wire cutting tool 47 of FIG. 10 in the above embodiment, a rod-shaped peeling tool 55 as shown in FIG. That is, as shown in FIG. 12B, a rod-shaped peeling tool 55 is fixed to the lower surface of the support plate 42 on the case lid 20 side. When the case lid 20 is slid forward in the closing direction, the rod-like stripping tool 55 functions as a guide portion in which the front portion in the forward direction of the peeling tool 55 has a “slope angle of relief in the closing direction slide”. When the 20 slides backward in the opening direction, it is attached to the support plate 42 in an inclined state so that the front portion of the peeling tool 55 in the backward direction functions as a breakage acting portion having the “tilt angle of inclination in the opening direction slide”. ing. In addition, as shown in FIGS. 12A and 12B, the tag 30 is inserted into the tag receiving recess 18 of the case body 10 so that the antenna surface of the wireless communication tag 30 is the lower surface, An adhesive is applied on the left and right bottom surfaces of the tag receiving recess 18, and an adhesive layer 56 is formed between the left and right bottom surfaces and the antenna surface (lower surface) of the wireless communication tag 30. That is, as shown in FIG. 12A, the left and right portions of the antenna surface of the wireless communication tag 30 are bonded to the left and right bottom surfaces of the tag receiving recess 18, respectively. Note that the wireless communication tag 30 used in the modified example of FIG. 12 is preferably a thin sheet-like tag. When the case lid 20 and the rod-shaped stripping tool 55 are slid in the opening direction by unauthorized opening in the substrate case having such a configuration, the tag-receiving recess 18 is moved by the rod-shaped stripping tool 55 that moves horizontally in the broken tool moving groove 17. The wireless communication tag 30 adhered to the bottom surface of the is peeled off from the recess 18. At that time, it is held by a part of the communication antenna 33 adhered to the left and right bottom surfaces of the tag receiving recess 18 and the central part of the tag main body 31 (parts excluding the left side and right side parts) to be peeled off by the rod-like peeling tool 55. A disconnection due to pulling occurs with a part of the communication antenna 33 that is present, and as a result, the wireless communication tag 30 is damaged and does not perform its original function (or becomes difficult to perform). As described above, when the substrate case is tampered with, the wireless communication tag 30 is damaged. Therefore, the configuration and the configuration shown in FIG. Therefore, the rod-like peeling tool 55 that is not a cutting tool can also be said to be a damaged tool for damaging the wireless communication tag 30.

  In the above embodiment, the case main body 10 is provided with the wireless communication tag 30 and the case lid 20 is provided with the cutter 43 as a breakage tool. However, the relationship between the case main body 10 and the case lid 20 may be reversed. That is, the displacement mechanism accommodating recess 23 on the case body 10 side, the spring 41 as the biasing means, the support plate 42 and the cutter 43 as the breaker are provided, and the cutter moving groove 17 and the tag accommodating recess on the case lid 20 side. 18 and the wireless communication tag 30 may be provided. In that case, when the case lid 20 is slid horizontally, the wireless communication tag 30 slides along with it, but the cutter 43 does not move, but relative movement occurs between the wireless communication tag 30 and the cutter 43. The essence of the invention is not particularly different from the above embodiment.

  In the above-described embodiment, the substrate case of the type in which the case lid 20 is attached to the case body 10 so as to be reciprocally slidable has been described. However, the application target of the present invention is not limited to this type. For example, as shown in FIG. 13, the present invention may be applied to a substrate case of a type in which the case lid 20 is attached to the case body 10 so as to be reciprocally rotatable about a rotation shaft 57. That is, the wireless communication tag 30 is provided inside one case body of the case body 10 and the case lid body 20, and a breakage tool (for example, the cutter 43) is disposed on the one case body side on the other case body. Provide to protrude. Then, the case lid 20 is opened from the closed position by disposing the other one so as to be positioned on one of the relative rotation paths of the damaged tool and the wireless communication tag 30 accompanying the rotation of the case lid 20. You may comprise so that a breaker may damage the radio | wireless communication tag 30 when it rotates toward a position.

In the gaming machine substrate case of the first aspect, the wireless communication device is provided inside one of the case body and the case lid. For this reason, 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 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, one of the wireless communication device and the damaged tool is disposed on the other relative movement path of the wireless communication device and the damaged tool accompanying the movement of the case lid. For this reason, 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, the radio provided in one of the case body and the case lid The communication device is forcibly broken by a breakage tool provided on the other case body. Since the wireless communication device damaged in this way cannot normally perform wireless data communication with the external inspection device, the external inspection device detects the abnormality of the wireless data communication and the board case is illegal. The fact that it was opened (or the possibility that there was a tampering) can be discovered.
[Invention 2]
Between a case main body for storing an electronic circuit board for gaming machines, a case lid attached to the case main body so as to be slidable back and forth between a closed position and an open position, and an external inspection device A wireless communication device capable of performing wireless data communication, and a breaker for damaging the wireless communication device, and one case body of the case body and the case lid body has a case body The wireless communication device is provided in the vicinity of the boundary surface between the two case bodies when the lid body is mounted, and the other case body of the case body and the case lid body is connected to the one case from the boundary surface. The breaker is provided so as to protrude toward the body, and one of the wireless communication device and the breaker is moved relative to the other of the wireless communication device and the breaker as the case lid slides. On the route The breaker or the wireless communication device is supported by a corresponding case body in a state of being movable in a direction intersecting the sliding direction of the case lid, and the breaker opens the case lid. When the sliding tool is slid from the position toward the closed position, the damaged tool or the wireless communication device that is movable in the crossing direction based on the contact with the wireless communication device is retracted in the crossing direction so that the wireless communication device is damaged by the damaged tool. A board for a gaming machine comprising: a guide portion for avoiding; and a damaging action portion for damaging the wireless communication device when the case lid is slid from the closed position toward the unsealed position. Case.

In the gaming machine substrate case according to the second aspect of the present invention, the wireless communication device is provided inside one case body of the case body and the case lid body and in the vicinity of the boundary surface between the two case bodies when the lid body is mounted. For this reason, 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 device is confined within 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, when the case lid is slid from the opened position toward the closed position to seal the substrate case, mutual contact (that is, mechanical interference) between the damaged tool and the wireless communication device is unavoidable. Even in such a case, the damaged tool can be moved by retracting the damaged tool or the wireless communication device in a direction intersecting the sliding direction of the case lid based on the contact with the wireless communication device. Since the guide part for avoiding damage to the wireless communication device due to the above is formed, the case lid can be safely placed at the closed position without damaging the wireless communication device, and the sealing of the substrate case can be completed. On the other hand, one of the wireless communication device and the damaged tool is disposed so as to be positioned on the other relative movement path of the wireless communication device and the damaged tool accompanying the movement of the case lid. For this reason, when the case lid is slid from the closed position toward the opening position in order to tamper open the sealed substrate case, the radio provided in one of the case body and the case lid The communication device is forcibly broken by the damaging portion of the damaging tool provided on the other case body. Since the wireless communication device damaged in this way cannot normally perform wireless data communication with the external inspection device, the external inspection device detects the abnormality of the wireless data communication and the board case is illegal. The fact that it has been opened (or the possibility of having been tampered with) can be discovered.
[Invention 3]
There is provided an urging means for urging the breakable tool or the wireless communication device movable in the intersecting direction toward a position where the breakage tool and the wireless communication device can contact when the case lid slides. A board case for a gaming machine according to the second aspect of the invention.

According to the third aspect of the present invention, the breakage tool or the wireless communication device that can move in the direction intersecting the sliding direction of the case lid is in contact with the breakage tool and the wireless communication device when the case lid is slid by the biasing means. It is biased toward a possible position. For this reason, even if the damaged tool or the wireless communication device is retracted in the crossing direction based on the contact between the damaged tool and the wireless communication device while the case lid is slid from the opening position toward the closed position, the case lid is damaged thereafter. When the contact between the tool and the wireless communication device is resolved, the urging means moves the damaged tool or the wireless communication device once retracted into the original position (when the case lid slides, the damaged tool and the wireless communication device contact each other). Forcibly return to a possible position). Therefore, when the case lid is slid from the closed position to the opened position in order to tamper open the substrate case after sealing, the damaging portion of the damaging tool surely acts on the wireless communication device, and wireless communication by the damaging tool is performed. The device can be reliably damaged.
