Description

  The present invention relates to a board case for a gaming machine that houses a control board installed in a gaming machine such as a slot machine or a pachinko machine.

  In recent years, in gaming machines such as pachinko machines and slot machines, an electronic circuit such as a ROM or a connector is provided in a board case that can be opened and closed by an upper case (first case member) and a lower case (second case member). A control board on which components are mounted is stored, and this board case is attached to a predetermined part of the gaming machine housing directly or via a mounting plate fixed to the lower case, and a gaming operation is performed by an electronic component such as a ROM on the control board side. An electronic control method for controlling is adopted.

  In this type of gaming machine, the electronic parts such as ROM mounted on the control board cannot be illegally exchanged, and at the same time, the inspection can be easily performed by opening the board case at the time of inspection or repair by the supervisory agency. It is necessary to do so.

  Therefore, as a substrate case by a so-called sealing method (sealing means), a first locking portion for locking the first case member and a second locking portion for locking the second case member are provided. Some include a connecting member that connects the case member and the second case member (see, for example, Patent Document 1). In this type of substrate case, the connecting member is held by the first mounting portion formed on the first case member.

JP 2009-82582 A

  In recent years, techniques for illegally replacing a control board in a board case have become more sophisticated. Even in the case of the substrate case by the sealing (sealing) method as described above, for example, a very sharp member is inserted between the first locking portion of the connecting member and the first mounting portion of the first case member. In some cases, an illegal act is performed by removing the connecting member without damaging it.

  Although it is difficult to completely prevent such fraud, it is also important to ensure that at least fraud has been performed. For this purpose, it is desirable that when a fraudulent act is performed, the connecting member is easily damaged greatly, and the damage is conspicuous.

  This invention is made | formed in view of said situation, and makes it a subject to make it easy to break the connection member used for sealing of a substrate case, when an improper act is performed. .

  The present invention is for solving the above-described problem, and includes a first case member that covers a front surface side of a control board provided in a gaming machine, a second case member that covers a back surface side of the control board, and a first case. A board case for a gaming machine having a connecting member for connecting and sealing the first case member and the second case member in a state where the member and the second case member accommodate the control board, wherein the connecting member is A first locking member that locks the first case member; a second locking member that is joined to the first locking member and locks the second case member; and the first case member A synthetic resin configured such that the first locking member is exposed from the first case member in a state where the second locking member is connected, and the first locking member has a lower impact strength than the second locking member. It is formed by a material.

  In such a configuration, in the state where the connecting member connects the first case member and the second case member, in order to release the connection without destroying the first case member and the second case member, regardless of fraud / fair. Any one of a method of destroying the connecting member and a method of releasing the connection without destroying the connecting member can be considered. When the deconsolidation is fair, the former method is used, but in this case, the trace remains. On the other hand, when taking the latter method, that is, when trying to release the connection illegally, it is necessary to apply some force (hereinafter referred to as a release force) to the connection member to release the connection.

  When the release force is applied to the connecting member, it is the first locking member of the connecting member that is exposed to the outside, and thus the release force and the resistance force against this are applied to the first locking member. It will be. Here, since the first locking member is formed of a material having a lower impact strength than the second locking member, that is, a fragile material, for example, in the gap between the first locking member and the first case member. When the tip of the inserted micro screwdriver is hooked on the edge of the first locking member and the connection is to be released by the lever principle, the release force acts locally on the edge of the first locking member. As a result, the first locking member is easily chipped or cracked, and as a result, traces remain. In addition, even if the release force is carefully released so that the release force does not act locally on a part of the first locking member, the drag is applied to the engaging portion of the first locking member with the first case member. Since it acts locally, this also causes chipping and cracking, resulting in traces.

  Therefore, it is very difficult to release the connection by the connecting member without leaving a trace on the first locking member of the connecting member. If an illegal act is performed, the first locking of the connecting member is not performed. Chips and cracks are easily generated in the member, and the traces remain. As a result, fraudulent acts can be prevented in advance, and discovery is facilitated when fraudulent acts are performed.

  In addition, in the gaming machine substrate case according to the present invention, the first locking member is formed of an AS resin material and the second locking member is formed of an ABS resin material. A structure in which and are joined by welding can be employed.

  According to such a configuration, generally, the AS resin has a lower impact strength than the ABS resin, and the AS resin and the ABS resin can be joined by welding without performing special interfacial processing or the like. , It has a feature that high bonding strength can be obtained after bonding. Therefore, although it is a connecting member formed by joining two members made of different resin materials with different impact strengths, it can be compared with a conventional connecting member made of a single material by selecting AS resin and ABS resin. The risk of separation of the two members on the joining surface and the cost increase associated with joining can be minimized.

  Further, in the gaming machine substrate case according to the present invention, the first locking member has a cylindrical shape in which one end is closed and the other end is opened, while the second locking member has one end. The first locking member has a rod-like shape joined to the inner bottom surface of the first locking member, and a first engaging portion that engages with the first case member protrudes from the outer peripheral surface of the first locking member. It is desirable that a second engagement portion that engages with the second case member is formed at the other end portion of the second case member.

  According to this configuration, the connecting member can reliably connect the first case member and the second case member by the first locking member and the second locking member.

  In the gaming machine board case according to the present invention, the first case member has a cylindrical mounting portion into which the first locking member of the connecting member is inserted, and the connecting member is connected to the first case member and the first case member. A recess that engages with the first engagement portion in a state where the two case members are connected is formed on the inner peripheral surface of the attachment portion, and the second locking member of the connection member is inserted through the bottom surface of the attachment portion. A first insertion hole is formed, the second case member is formed with a second insertion hole communicating with the first insertion hole, and the second engagement portion is engaged with an edge of the second insertion hole. It is desirable to combine.

  According to such a configuration, in the connecting member, the first engaging portion of the first locking member is engaged with the recess provided in the mounting portion of the first case member, and the second engaging portion of the second locking member is By engaging with the edge of the second insertion hole of the second case member, the first case member and the second case member can be reliably connected.

  In addition, the gaming machine substrate case according to the present invention is a first locking member of the connecting member exposed from the first case member in a state where the connecting member connects the first case member and the second case member. And when the shaft portion of the second locking member inside thereof is cut along a plane substantially perpendicular to the shaft portion, the first engaging portion of the first locking member and the While the engagement of the first case member with the concave portion is maintained, a part of the second locking member passes through the first insertion hole of the first case member and the second insertion hole of the second case member to form the second case. It is possible to adopt a configuration that falls into the member and is maintained in the second case member.

  According to such a configuration, a part of the first locking member of the connecting member exposed from the first case member and the shaft portion of the second locking member inside thereof are along a surface substantially perpendicular to the shaft portion. When cut, that is, when the case is opened, a part of the connecting member remains in each of the first case member and the second case member even after the case is opened. Thereby, the trace that it was opened fairly can be left.

  According to the present invention, when an illegal act is performed, the connecting member used for sealing the substrate case can be easily damaged.

The diameter of the first insertion hole 48 is smaller than the outer diameter of the first locking member 36. In addition, a first recess (not shown) in which the first engagement claw 41 of the connecting member 33 fits and a second recess 52 in which the second engagement claw 42 fits are formed on the inner peripheral surface of the first mounting portion 47. Has been.

  The receiving member 34 is formed in a rectangular parallelepiped shape having a hollow inside. The receiving member 34 is fixed to the mounting plate 26. As shown in FIGS. 8 to 10, the receiving member 34 is formed with a plurality of first storage portions 54 in which the second locking members 37 of the coupling member 33 are stored. The first storage portion 54 is provided corresponding to the first case member 25a.

  The first storage portion 54 is second when a plurality of partition wall portions 55 forming a storage space for the second locking member 37 inside the receiving member 34 and the connecting member 33 seals the substrate case 25. A first latching portion 56 that latches the latching claw 37b of the latching member 37 and a second latching member 37 that prevents the second latching member 37 from being detached from the first storage portion 54 when the sealing is released. It has 1 retaining part 57. The partition wall portion 55 forms a storage space (first storage portion 54) for the second locking member 37 together with the side wall of the receiving member 34.

  The first hooking portion 56 has a quadrangular shape in plan view, and is formed so as to protrude from the top surface 34 a of the receiving member 34. The first latching portion 56 is provided with a latching wall 61 that latches the latching claw 37 b of the second latching member 37. The retaining wall 61 is formed with a circular second insertion hole 62 through which the second locking member 37 is inserted.

A circular third insertion hole 67 through which the second locking member 37 is inserted is formed in the retaining wall 66. The third insertion hole 67 is formed concentrically with the second insertion hole 62 of the retaining wall 61 in plan view.

  The connecting member 33 of the first sealing means 30 is in a standby state where the first case member 25a and the second case member 25b are not connected to each other (see FIG. 8), and the first case member 25a and the second case member 25b. In a state where the coupled (connected) state is maintained, the substrate case 25 is fixed to the housing 2 side and sealed to a sealed state (see FIG. 9), and the sealed state is released (see FIG. 10). The state can be changed.

  Hereinafter, an operation when the state of the connecting member 33 is changed from the standby state to the sealed state and when the state is changed from the sealed state to the released state will be described.

  As shown in FIG. 8, when the connecting member 33 is in the standby state (standby position), the first engagement claw 41 of the first locking member 36 is fitted in the first recess of the first mounting portion 47. . Thereby, the connecting member 33 is held by the first mounting portion 47. At this time, the locking claw 37 b of the second locking member 37 is located in the first mounting portion 47.

  When the first locking member 36 is pushed from this position, as shown in FIG. 9, the first engaging claw 41 fitted in the first recess is detached from the first recess. When the first locking member 36 is further pushed, the tip of the locking claw 37 b of the second locking member 37 is inserted into the second insertion hole 62 through the first insertion hole 48.

  At this time, the bifurcated locking claw 37b is inserted into the second insertion hole 62 with elastic deformation so that the interval between the two is narrowed. Further, when the first locking member 36 is pushed and the locking claw 37 b exceeds the locking wall 61 of the first locking part 56 of the receiving member 34, the locking claw 37 b is hooked by the first locking part 56. It hits the stop wall 61 and is held by locking the edge of the second insertion hole 62. At this time, the middle part of the locking claw 37b remains elastically deformed (contracted), and the edge part of the first insertion hole 48 and the edge part of the second insertion hole 62 (the wall surface of the first retaining wall 61). Abut. In this state, the second engagement claw 42 of the first locking member 36 is fitted into the second recess 52.

  As described above, the substrate case 25 is fixed to the housing 2 side via the receiving member 34 and the mounting plate 26 while maintaining the state where the first case member 25a and the second case member 25b are connected. Sealed. In this sealed state, a part of the first locking member 36 is exposed from the first case member 25a. More specifically, in the sealed state, the closing portion 36a of the first locking member 36 is exposed from the first mounting portion 47 in a state of being in the first mounting portion 47 of the first case member 25a. It is in a state.

  In this state, for example, if a pointed tool is applied to the first locking member 36 to try to comprehend this sealing, the first locking member 36 itself having a lower impact strength than the second locking member 37 is used. The connecting member 33 is greatly damaged due to breakage or release of the joining by the joining portion 38. Thereby, the trace which shows that the fraudulent act was performed becomes a conspicuous state, and the early detection of a fraudulent act is attained.

  In order to release the sealing, first, as shown in FIG. 10, the first locking member 36 of the connecting member 33 housed in the first mounting portion 47 is broken (cut) at a predetermined position. A nipper or other cutting tool is used for breaking. For example, the breakage is desirably performed at a position corresponding to the recess 36 d formed on the inner surface of the closing portion 36 a of the first locking member 36. This is because the thickness of the blocking portion 36a at this position is reduced due to the formation of the concave portion 36d and is easily broken. In addition, the fracture is performed along a surface substantially perpendicular to the axial direction of the shaft portion (body portion 37a) of the second locking member 37 or a surface substantially perpendicular to the axial direction of the shaft portion. Is desirable.

  When the first locking member 36 is broken at a predetermined position and the broken portion is removed, the blocking of the end portion of the first locking member 36 by the blocking portion 36a is released. At this time, a part of the trunk portion 37a of the second locking member 37 is also excised. As a result, the joint 38 of the connecting member 33 is also removed, and the first locking member 36 and the second locking member 37 are separated. Thereby, the trunk | drum 37a of the 2nd latching member 37 covered with the 1st latching member 36 is exposed.

  In this state, as shown in FIG. 10, the middle portion of the locking claw 37 b of the second locking member 37 contacts the edge of the first insertion hole 48 and the edge of the second insertion hole 67 by elastic deformation. The state remains. That is, in the connecting member 33, a part of the first locking member 36 and a part of the second locking member 37 are cut away, and the joining of the first locking member 36 and the second locking member 37 is released. However, the second locking member 37 can maintain the position in the sealed state without falling downward.

  When the upper portion of the second locking member 37 is pressed downward from this state, the second locking member 37 moves to the first storage portion 54 side. At this time, the second locking member 37 is inserted into the third insertion hole 67 while being elastically deformed so that the interval between the two locking claws 37b becomes narrow. When the second locking member 37 is further pushed and the locking claw 37 b exceeds the third insertion hole 67, the locking claw 37 b is locked by the retaining wall 66. As a result, the second locking member 37 falls into the second case member 25b, and the second locking member 37 is prevented from coming off.

  As described above, the sealing of the substrate case 25 by the first sealing means 30 is released, and the substrate case 25 can be removed from the housing 2 side. Thus, when the sealing of the first sealing means 30 is released (released state), the first engaging member 36 separated from the second engaging member 37 has the second engaging claw 42 in the second recessed portion. The first mounting portion 47 is held in a state where it is fitted to 52 (prevented from coming off). Further, the second locking member 37 remains in a state where the second locking member 37 is prevented from being detached in the first storage portion 54, and the trace of the seal release remains on the substrate case 25 and the receiving member 34. It is possible to confirm whether or not the sealing has been released after the fact.

  As shown in FIG. 5, the second sealing unit 31 includes a connecting member 33 that connects the first case member 25 a and the second case member 25 b. This connecting member 33 is the same as the first sealing means 30.

  As shown in FIG. 4, the 1st case member 25a is provided with the 2nd attaching part 68 for attaching this connection member 33. As shown in FIG. In this embodiment, two second attachment portions 68, 68 are formed on the first case member 25a. The second attachment portion 68 is formed side by side with the first attachment portion 47 in one row. In this embodiment, the two second attachment portions 68 and 68 are arranged so as to sandwich the four first attachment portions 47 in the width direction of the first case member 25a.

  The second attachment portion 68 is formed in a cylindrical shape like the first attachment portion 47, and a fourth insertion hole 70 through which the second locking member 37 of the connecting member 33 is inserted is formed at the bottom thereof. The fourth insertion hole 70 has a circular edge. The diameter of the fourth insertion hole 70 is equal to the diameter of the first insertion hole 48. A third recess (not shown) and a fourth recess 85 in which the first engagement claw 41 and the second engagement claw 42 of the first locking member 36 are fitted are formed on the inner surface of the second attachment portion 68. .

  As shown in FIGS. 8 to 10, the second case member 25 b is formed with a second storage portion 87 that stores the second locking member 37 of the connecting member 33 of the second sealing means 31. In this embodiment, two second storage portions 87 and 87 are provided in the second case member 25b corresponding to the two second attachment portions 68 and 68, respectively. This 2nd accommodating part 87 latches the 2nd latching member 37 of the connection member 33, when the connection member 33 is sealing in the state which connected the 1st case member 25a and the 2nd case member 25b. The second latching portion 88 has a second retaining portion 89 that prevents the second locking member 37 from coming off from the second storage portion 87 when the sealing is released.

  Similarly to the first hook 56, the second hook 88 hooks the locking claws 37 b of the second locking member 37 when the substrate case 25 is sealed by the second sealing means 31. A second retaining wall 88a is provided. A fifth insertion hole 88b through which the locking claw 37b is inserted is formed in the second hooking wall 88a. The fifth insertion hole 88b has a circular edge. The diameter of the fifth insertion hole 88 b is equal to the diameter of the second insertion hole 62. In the sealed state, the locking claw 37b of the second locking member 36 comes into contact with the second retaining wall 88b in a state where the locking claw 37b is pulled out from the fifth insertion hole 88b to the second storage portion 87 side, and the fifth insertion hole The edge part of 88b is latched.

  In this sealed state, a part of the first locking member 36 is exposed from the first case member 25a. More specifically, in the sealed state, the closing portion 36a of the first locking member 36 is exposed from the second mounting portion 68 in a state of entering the second mounting portion 68 of the first case member 25a. It is in a state.

  The second retaining portion 89 has a sixth insertion through which the locking claw 37b of the second locking member 37 of the second sealing means 31 is inserted when the sealing by the second sealing means 31 is released. It has a hole 89a. The inner diameter of the sixth insertion hole 89a is slightly smaller than the distance between the ends of the two locking claws 37b of the connecting member 33.

  Similar to the first sealing means 30, the second sealing means 31 can change the state of the connecting member 33 from the standby state to the sealed state and from the sealed state to the released state. That is, the connection member 33 of the second sealing means 31 is held by the second attachment portion 68 when in the standby state. More specifically, the first engagement claw 41 formed on the first locking member 36 is fitted in the third recess of the second attachment portion.

  When the standby state is changed to the sealed state, the first locking member 36 of the connecting member 33 is locked in the second attachment portion 68 of the first case member 25a. More specifically, the second engagement claw 42 of the first locking member is fitted into the fourth recess 85 of the second attachment portion 68.

  Further, in the sealed state, the first case member 25a is in a state where the locking claw 37b of the second locking member 37 is hooked on the second locking wall 88a of the second storage portion 87 of the second case member 25b. And the connection state of the 2nd case member 25b is maintained. In this state, as in the case of the first sealing means 30, when trying to comprehend this sealing, the connecting member 33 is greatly damaged, and a trace indicating that an illegal act has been performed becomes conspicuous.

  Further, when the sealing by the second sealing means 31 is released, as in the case of the sealing release of the first sealing means 30, after a part of the first locking member 36 is excised, The covering of the second locking member 37 by the first locking member 36 is released, and the joint portion 38 is also removed. Thereby, the 1st locking member 36 and the 2nd locking member 37 are isolate | separated. Then, the locking claw 37b of the second locking member 37 is locked by the second retaining portion 89 through the sixth insertion hole 89a. As a result, the second locking member 37 remains on the second case member 25b side in a retaining state, and the first locking member 36 is retained in the second mounting portion 68 of the first case member 25a. Remains. As described above, the connection between the first case member 25a and the second case member 25b is released.

  According to the substrate case 25 in the present embodiment described above, the first locking member 36 has a lower impact strength than the second locking member 36 (for example, the first locking member 36 is made of AS resin, the second When the locking member 37 is formed of ABS resin), when the sealing by the connecting member 33 is illegally released, the connecting member 33 is greatly damaged, and the trace of the damage becomes conspicuous. Is easier to discover.

  In addition, the joint portion 38 is in contact with a part of the end portion (end surface 37 c) of the body portion 37 a of the second locking member 37 and the projection portion 36 c formed on the inner surface of the closing portion 36 a of the first locking member 36. Since the entire surface of the end surface 37c of the body portion 37a is in contact with the inner surface of the first locking member 36, the contact area is made as small as possible, so that the joining force is reduced. Can be set weakly. Even when the first locking member 36 is illegally operated, the joining by the joining portion 38 is easily released easily, and the connecting member 33 is greatly damaged, and the trace of fraud is made conspicuous. Is possible.

  This will be described in more detail. In a state where the connecting member 33 connects the first case member 25a and the second case member 25b, the connection can be made without destroying the first case member 25a and the second case member 25b. In order to cancel the connection, any one of a method of destroying the connecting member 33 and a method of releasing the connection without destroying the connecting member 33 can be considered regardless of fraud. When the deconsolidation is fair, the former method is used, but in this case, the trace remains. On the other hand, when taking the latter method, that is, when trying to release the connection illegally, it is necessary to apply a release force to the connection member 33 to release the connection.

  When a release force is applied to the connecting member 33, the first locking member 36 of the connecting member 33 is exposed to the outside. Therefore, the release force and the resistance against this are applied to the first locking member 36. Will act. Here, since the first locking member 36 is formed of a material having a lower impact strength than the second locking member 37, that is, a fragile material, for example, the first locking member 36 and the first case member 25a. When the tip of the micro driver inserted into the gap between the first and second locking members 36 is hooked on the edge of the first locking member 36 to release the connection by the lever principle, the release force is applied to the edge of the first locking member 36. As a result, the first locking member 36 is easily chipped and cracked, and as a result, traces remain. Further, even if careful release is attempted so that the release force does not act locally on a part of the first locking member 36, the first locking member 36 may be engaged with the first case member 36. Since the above-mentioned drag acts locally, this also causes chipping and cracking, resulting in traces remaining.

  Therefore, it is very difficult to release the connection by the connecting member 33 without leaving a trace on the first locking member 36 of the connecting member 33. If an illegal act is performed, The first locking member 36 is easily chipped or cracked, and the trace remains. As a result, fraudulent acts can be prevented in advance, and discovery is facilitated when fraudulent acts are performed.

  The connecting member 33 includes the first locking member 36 formed of AS resin material and the second locking member 37 formed of ABS resin material, and the first locking member 36 and the second locking member 37 are welded together. It is joined by.

  Thereby, it becomes possible to join AS resin and ABS resin by welding, without performing special interface processing. Further, the connecting member 33 has a feature that a high bonding strength can be obtained after the first locking member 36 and the second locking member 36 are bonded. Accordingly, although the connecting member 33 is formed by joining two members formed of different resin materials having different impact strengths, it can be compared with the conventional connecting member 33 formed of a single material by selecting the AS resin and the ABS resin. In comparison, it is possible to minimize the risk of separation of the two members on the joining surface and the cost increase related to joining.

  Furthermore, since the trunk | drum 37a of the 2nd latching member 37 is comprised by the cylinder shape or rod shape, and is hollow, it can be cut | disconnected easily in the case of cancellation | release of sealing.

  The first locking member 36 of the connecting member 33 has a cylindrical shape with one end closed and the other end opened, while the second locking member 37 has one end of the first locking member. A first engagement portion (second engagement claw 42) that has a rod shape joined to the inner bottom surface and engages with the first case member 25 a is provided on the outer peripheral surface of the first locking member 36. A second engaging portion (locking claw 37b) that engages with the second case member is formed at the other end of the two locking members. Accordingly, the connecting member 33 can reliably connect the first case member 25 a and the second case member 25 b by the first locking member 36 and the second locking member 37.

  In the connecting member 33, the first engaging portion (second engaging claw 42) of the first locking member 36 is engaged with the second recess 52 provided in the first mounting portion 47 of the first case member 25a. When the second engaging portion (the locking claw 37b) of the second locking member 37 is engaged with the edge of the second insertion hole 62 of the second case member 25b, the first case member 25a and the second case The member 25b can be reliably connected.

  Further, when the connecting member 33 is cut to release the sealing, the first engaging portion (second engaging claw 42) of the first locking member 36 and the first case member 25a are also cut after cutting. While the engagement with the second recess 52 is maintained, a part of the second locking member 37 is second through the first insertion hole 48 of the first case member 25a and the second insertion hole 62 of the second case member 25b. It falls into the case member 25b and is maintained in the second case member 25b.

  As a result, a part of the first locking member 36 of the connecting member 33 exposed from the first case member 25a and the shaft portion (body portion 37a) of the second locking member 37 inside thereof are substantially omitted from the shaft portion. When cut along a vertical plane, that is, when the case is opened, a part of the connecting member 33 remains in each of the first case member 25a and the second case member 25b even after the case is opened. Thereby, the trace that it was opened fairly can be left.

  The substrate case according to the present invention is not limited to the above embodiment, and various modifications and changes can be made.

  For example, in the above-described embodiment, the first locking member 36 is made of AS resin and the second locking member 37 is made of ABS resin. The second locking member 37 may be made of other synthetic resin.

  In the above-described embodiment, the example in which the two locking claws 37b are formed on the second locking member 37 has been described. However, the present invention is not limited to this. 37 may be formed. Similarly, three or more first engaging claws 41 and second engaging claws 42 may be formed on the first locking member 36.
