Description

  The present invention relates to a gaming machine such as a pachinko machine or a slot machine, and more specifically, a board case composed of first and second case bodies that can be fitted together with a board sandwiched therebetween, and the board case sealed in a closed state. The present invention relates to a gaming machine having a sealing means that can be stopped.

  In gaming machines such as pachinko machines, various control boards and the like are mounted on the back side of the main body and the like while being stored in a board case. A general substrate case is configured to have a substantially box shape by combining a first case body and a second case body so as to be openable and closable.

  Some board cases of gaming machines are provided with sealing means for preventing fraud with respect to the control board. This sealing means seals the first case body and the second case body in a closed state so that the current state cannot be restored. Once the control board is stored and stored, the damaged portion is damaged. Unless the trace of opening is left, the substrate case cannot be opened and the internal control board cannot be taken out.

  As this type of substrate case and its sealing means, for example, those described in Patent Documents 1 and 2 are common. In any of the gaming machines described in each of these patent documents, the sealing member held by the holding member on the second case body side remains in the state held by the holding member on the second case body side. The board case is sealed by being coupled to the body-side coupled portion, that is, by coupling the holding member on the second case body side and the coupled portion on the first case body side by the sealing member. .

  However, these conventional substrate cases and their sealing means are configured to couple the sealing member to the coupled portion on the first case body side while the sealing member is held by the holding member on the second case body side. Therefore, it is impossible or extremely difficult to integrally mold the sealing member and the holding member on the second case body side. Therefore, for example, the sealing member is a member different from the second case body. There was a need to do. As a result, the conventional gaming machine has problems such as an increase in the number of parts and an increase in cost due to a complicated assembly process.

  Therefore, the applicant of the present invention relates to an invention relating to a gaming machine (hereinafter referred to as a prior application invention) capable of minimizing the number of parts by allowing a sealing member constituting a sealing means to be formed integrally with a substrate case. ) Has already been filed (Japanese Patent Application No. 2007-188444).

In the prior invention, the first case body and the second case body can be slid relative to each other between a locked state in which the coupling state is locked and an unlocked state in which the first case body is locked, and an opening failure is caused on the second case body side. When the part and the sealing member are integrally provided and sealed, the sealing member is separated from the second case body and is detachably coupled to the first case body side so that the sealing member becomes the second case. The sliding movement of the body side unsealable part to the unlocked state is restricted and the unsealing is prevented, and when opening normally, by removing the unsealable part from the second case body, The sliding movement to the unlocked state side is allowed.

The contact portion 124 is separated from the sealing member 92 in a state where the sealing member 92 is connected to the second case body 42 side by the holding portion 115 (FIG. 20), and the sealing member 92 is in the second case. When separated from the body 42 and joined to the first case body 41 side (FIG. 21), the outer surface side of the front wall 116c of the sealing member 92 comes into contact with or is close to.

  As shown in FIG. 17 and the like, the first damaged portion 121 includes an outer peripheral frame 69 on the left and right sides in the sliding direction at the outer end portion of the support plate 123 and the edge of the sealing opening 101 or in the vicinity thereof, for example, on the high wall 67 side. Are connected to each other, and can be easily damaged from the outside of the main board case 24 by a nipper or the like.

  Further, as shown in FIG. 14, FIG. 15 and the like, the second damaged portion 122 includes an inner end portion of the support plate 123, an edge portion of the low wall opening portion 101c or the vicinity thereof, for example, a low wall 66 and a partition wall 57. Are provided so as to be connected across the inside of the low wall opening 101c in the sliding direction. For example, the outer edge thereof is substantially flush with the low wall 66, and the inner edge thereof is the surface 94a of the fitting support portion 94. It is formed in a wide shape in the inner and outer direction that is in contact with or close to, and can be damaged from the outside of the main substrate case 24 by a nipper or the like.

  The second damaged portion 122 is disposed in an inwardly recessed portion 125 constituted by the low wall 66, the upright wall 68 standing on both sides of the low wall 66, and the side wall 61a of the bulging portion 61. Moreover, since it is formed in a wide shape in the inner and outer directions, the damage operation is slightly more difficult than the first damaged part 121.

  As described above, the coupled portion 91, the sealing member 92, and the opening obstruction portion 93 constituting the sealing means 43 are all integrally formed with the first case body 41 or the second case body 42 of the main board case 24. There is no separate part. That is, since the main board case 24 has only two components, the first case body 41 and the second case body 42, the number of parts is larger than that of the conventional board case in which the sealing member 92 is a separate part, for example. In addition, the number of assembly steps can be reduced, and the cost can be reduced.

  When the second case body 42 to which the main control board 23 is attached is attached to the first case body 41 and sealed, first, the pair of engaging protrusions 58 on the second case body 42 side are first connected to the first case body 41. After being inserted into the engaged hole 87 along the guide grooves 78 and 79 on the 41 side from the inside, the engaging claw 70 on the second case body 42 side is fitted into the notch 81 on the first case body 41 side. To fit into the unlocked state (FIG. 18 → FIG. 19). At this time, the engaging portion 47a on the main control board 23 side and the engaged portion 89a on the first case body 41 side are separated from each other in the sliding direction and are in a disengaged state. Further, the right peripheral wall 54 on the second case body 42 side and the right fitting wall 75 on the first case body 41 side are separated from each other, and the sealing member 92 on the second case body 42 side is separated from the first case body 41. It will be in the state which contact | abutted or adjoined to the inner surface side of the side wall 72 of the side.

  Then, the second case body 42 and the first case body 41 are relatively slid in a direction in which the right peripheral wall 54 and the right fitting wall 75 approach each other (FIG. 19 → FIG. 20). Thereby, the engaging claw 70 on the second case body 42 side is engaged with the engaging portion 82 on the first case body 41 side, and the first case body 41 and the second case body 42 are locked in a coupled state. At the same time, the engaging portion 47a on the main control board 23 side and the engaged portion 89a on the first case body 41 side approach each other and engage in a direction substantially perpendicular to the plate surface of the main control board 23. Further, the sealing member 92 on the second case body 42 side is separated from the side wall 72 on the first case body 41 side, and is in a state of being aligned with the coupled portion 91 on the first case body 41 side in the inner and outer directions.

  Further, even when the main lock means 86 is in the locked state in this way, the auxiliary lock means 88 is maintained in a state where the engagement protrusion 58 is engaged with the engaged hole 87.

  Subsequently, the main substrate case 24 is sealed using one of a plurality (four sets) of sealing means 43. That is, first, a cutting tool such as a nipper is used to cut all the holding portions 115 connected to the sealing member 92 used for sealing, and the sealing member 92 is separated from the second case body 42, and a driver or the like. The tip of the tool is applied to the recess 114a of the operated portion 114 of the sealing member 92 and pressed toward the inside, that is, the first case body 41 side.

  As a result, the sealing member 92 is fitted into the insertion slit 95 while the coupling portion 113 on the distal end side spreads the elastic engagement portion 97 to both sides. At this time, the sealing member 92 is guided straight in the pressing direction by sliding along the guide plates 98, 98, the restricting portion 99, and the contact portion 124 provided around the sealing member 92. When the flange portion 112 of the sealing member 92 contacts the surface 94a of the fitting support portion 94, the coupling portion 113 penetrates the insertion slit 95 and engages with the back side of the elastic engagement portion 97, and the sealing portion The stop member 92 is in a state in which it is detachably coupled to the first case body 41 side in a state of being completely independent from the second case body 42 (FIG. 21).

  At this time, the contact portion 124 of the unsealing obstruction portion 93 corresponding to the sealing member 92 is in contact with or close to the surface on the sliding direction lock side of the sealing member 92, that is, the outer surface side of the front wall 116c. Become. Therefore, in this state, even if the second case body 42 and the first case body 41 are relatively slid in the opening direction, that is, the direction in which the right peripheral wall 54 and the right fitting wall 75 are separated from each other, Since the sealing member 92 coupled to the 1 case body 41 side interferes with the opening obstruction part 93 on the second case body 42 side, the main board case 24 cannot be opened as it is.

  When the main substrate case 24 is opened for inspection or the like, the first and second damaged parts 121 and 122 of the sealing means 43 in a sealed state are cut using a cutting tool such as a nipper, As shown in FIG. 22A, the unsealable portion 93 is separated from the second case body 42 and removed. As a result, the standing wall opening 101b and the low wall opening 101c are opened, and there is nothing that restricts the movement of the sealing member 92 coupled to the first case body 41 side (FIG. 22B). The first case body 41 and the second case body 42 can be relatively slid to the unlocked state. In this unlocked state, the engaged state between the engaging claw 70 on the second case body 42 side and the engaging portion 82 on the first case body 41 side is released, and the engaging portion 47a on the main control board 23 side Since the engaged state with the engaged portion 89a on the first case body 41 side is also released (the state shown in FIG. 19), the first case body 41 and the second case body 42 are separated and the main board case 24 is separated. Can be released.

  Further, without properly releasing the sealing by the sealing means 43, for example, the engagement between the engaging claw 70 and the engaging portion 82 is forcibly performed by deforming the first case body 41 and the second case body 42 or the like. And the main board case 24 is opened, the engaging portion 47a on the main control board 23 side and the engaged portion 89a on the first case body 41 side are engaged with each other. Since the second case body 42 and the main control board 23 are separated from the one case body 41, the engaging portion 47a is caught by the engaged portion 89a and is damaged at the low strength portion 49 as shown in FIG. Therefore, for example, even if the first case body 41 and the second case body 42 are connected to each other after that, the engaging portion 47a remains broken. It can be determined whether there has been an unauthorized opening.

  As shown in FIGS. 3 to 6, the main board case mounting portion 31 is disposed along the mounting opening 131 provided on the back side of the ball collecting case 22 and the upper and lower edges of the mounting opening 131. The mounting rail 132, the first support means 133 that supports one end side of the main board case 24, the second support means 134 that supports the other end side of the main board case 24, and the first from the outside of the main board case 24 And a sealing cover 135 that covers at least a part of the second damaged portions 121 and 122.

  The mounting opening 131 is formed in a substantially rectangular shape corresponding to the main board case 24, and mounting rails 132 are extended inwardly along the upper and lower edges.

  The first support means 133 supports one end side, for example, the left end side, of the main board case 24, and is constituted by a recessed portion with which the protruding portion 84 on the main substrate case 24 side can be engaged. Is provided on the left end side of the mounting opening 131.

  The second support means 134 releasably supports the other end side of the main board case 24, for example, the right end side, and is a release that does not engage with the engagement position that engages the protruding portion 85 on the main board case 24 side. The fastening knob is switchable to a position, and is provided on the right end side of the mounting opening 131 corresponding to the protruding portion 85.

  When the main board case 24 is mounted on the main board case mounting portion 31, the front side of the main board case 24 (the outer surface side of the first case body 41) is placed along the mounting rail 132, and is first protruded on the left end side. The protrusion 84 may be locked by fitting the portion 84 to the first support means 133 and then switching the second support means 134 from the release position to the engagement position.

  The sealing cover 135 is integrally provided on the rear side of the main substrate case mounting portion 31 so as to cover the end portion of the main substrate case 24 mounted on the main substrate case mounting portion 31 on the sealing region 24b side. A cover plate portion 141 disposed substantially parallel to the main substrate case mounting portion 31 along the sealing-side upper wall 51b of the substrate case 24, upper and lower peripheral walls 52 and 53 on the main substrate case 24 side, and a side wall 72 on the left end side. A connecting plate portion 142 for connecting the edge portion of the cover plate portion 141 and the main substrate case mounting portion 31 is formed in a box shape in which the detachable side of the main substrate case 24, that is, the right side is opened.

  The cover plate portion 141 is formed in a rectangular plate shape having a size that covers substantially the entire sealing means 43 including the first and second damaged portions 121 and 122. In addition, it is desirable that at least the cover plate part 141 is transparent in the sealing cover 135 so that the sealing / opening state by the sealing means 43 can be visually recognized from the outside.

  Thus, since the first and second damaged parts 121 and 122 are covered with the sealing cover 135 when the main board case 24 is mounted on the main board case mounting part 31, the main board case 24 is opened as it is. I can't. In order to break the first and second breakage parts 121 and 122 and open the main board case 24, it is necessary to first release the second support means 134 and remove the main board case 24 from the main board case mounting part 31. For this reason, it takes much time, and it is possible to effectively prevent a go-to action due to replacement of ROM or the like.

  As described above, the pachinko machine of this embodiment is provided with the engaging portion 47a on the main control board 23 side and the engaged portion 89a corresponding to the engaging portion 47a on the first case body 41 side. The joint portion 47a is supported on the main control board 23 side via a low-strength portion 49 that is easily damaged. The engaging portion 47a and the engaged portion 89a are locked by the first and second case bodies 41 and 42. The first and second case bodies 41 and 42 are engaged with each other in the fitting / removing direction in the state, and the engagement is released in the unlocked state. If it is opened without a slide movement to the state, that is, by an opening method different from the normal opening method, the engaging portion 47a and the engaged portion 89a are forcedly engaged with each other. As a result, the engaging portion 47 a is broken at the low strength portion 49. Therefore, for example, even if the first case body 41 and the second case body 42 are connected to each other after that, the engaging portion 47a remains broken. It can be determined whether or not the tampering has occurred, and the fact that the fraud has been performed can be surely found.

  The first and second case bodies 41 and 42 can be slid relative to each other in the direction along the plate surface of the main control board 23 between the unlocked state and the locked state, and the main control is performed in the unlocked state. The engaging portion 47a and the engaged portion 89a can be fitted and detached in a direction substantially perpendicular to the plate surface of the substrate 23. The engaging portion 47a and the engaged portion 89a are in the main control substrate 23 when the first and second case bodies 41 and 42 are in the locked state. The engaging portion 47a and the engaged portion 89a can be freely engaged and disengaged along the plate surface of the main control board 23. The engaging portion 47a can be configured in a simple shape such as an L shape.

  Since the engaging portion 47a is integrally formed with the socket 44b for the ROM 44a attached to the main control board 23 through the low strength portion 49, the engaging portion 47a is newly attached to the main control board 23 as a separate part. The cost can be reduced compared to the case of doing so.

  24 and 25 exemplify a second embodiment of the present invention. The unauthorized opening detection unit 47 provided with the engaging portion 47a on the first case body 41 side is shown on the main control board 23 side. An example is shown in which engaged portions 89a corresponding to each are arranged.

  As shown in FIG. 24, the tampering detection unit 47 integrally includes an engaging part 47a arranged in parallel to the main control board 23, and the engaging part 47a and the bottom wall 71 on the first case body 41 side.

The support leg 47b protrudes to the electronic component mounting surface 23a side of the main control board 23 through an opening (or notch-shaped) insertion portion 151 provided in the main control board 23, and the electronic component from the front end side thereof. An engaging portion 47a extends along the mounting surface 23a. The engaging portion 47a and the supporting leg portion 47b are both plate-like, and for example, the engaging portion 47a is formed to be thinner than the supporting leg portion 47b, and the supporting leg portion 47b and the engaging portion 47a The connecting portion constitutes a low strength portion 49 that is easily damaged.

  Further, the edge of the opening 48 provided on the main control board 23 side is an engaged portion 89a, and when the first case body 41 and the second case body 42 are in the locked state (see FIG. 24). The engagement portion 47a and the engaged portion 89a engage with each other in a direction substantially perpendicular to the plate surface of the main control board 23, that is, in the fitting / removing direction of the first case body 41 and the second case body 42. When the first case body 41 and the second case body 42 are in the unlocked state (indicated by a two-dot chain line in FIG. 24), the engagement is released.

  Thus, even when the engaging portion 47a is provided on the first case body 41 side and the engaged portion 89a is provided on the main control board 23 side, the sealing by the sealing means 43 is not released properly, for example, If the main board case 24 is opened by forcibly releasing the engagement between the engaging claw 70 and the locking portion 82 by deforming the first case body 41 and the second case body 42, the first case body 41 and the second case body 42 are As in the case of the embodiment, the engaging portion 47a is caught by the engaged portion 89a and is damaged at the low-strength portion 49 (FIG. 25). Therefore, for example, even if the first case body 41 and the second case body 42 are connected to each other after that, the engaging portion 47a remains broken. It can be determined whether there has been an unauthorized opening.

  26 to 28 exemplify the third embodiment of the present invention. An unauthorized opening detection unit 47 having an engagement portion 47a is provided integrally with the main control board 23, and the first case body 41 is engaged with the engagement. The example provided with the to-be-engaged means 89 provided with the to-be-engaged part 89a corresponding to the part 47a is shown.

  As shown in FIGS. 26 and 27, the main control board 23 has an opening (or notch-shaped) insertion portion 151, which is illegal from the edge of the insertion portion 151 toward the insertion portion 151. The engaging part 47a of the opening detection part 47 is integrally formed in a protruding shape. The connecting portion between the engaging portion 47a and the edge of the insertion portion 151 is a low-strength portion 49 whose width is narrower than that of the engaging portion 47a.

  Further, a part of the wiring 152 constituting the game control circuit mounted on the main control board 23 is drawn on the engaging portion 47 a through the low strength portion 49. The wiring 152 is connected to, for example, an error processing unit on the game control circuit. When the wiring 152 is disconnected, predetermined error processing, for example, output of an error warning sound is performed by the error processing unit. Yes.

  In addition, the engaged means 89 corresponding to the unauthorized opening detection unit 47 protrudes toward the electronic component mounting surface 23a via the insertion part 151 on the main control board 23 side, so that the bottom wall 71 of the first case body 41 is exposed. For example, a substantially rectangular plate-like engaged portion 89a disposed along the electronic component mounting surface 23a of the main control board 23, and the three sides and bottom wall of the engaged portion 89a. 71 and a pair of side wall portions 89c are provided.

  Then, the unauthorized opening detection unit 47 on the main control board 23 side and the engaged means 89 on the first case body 41 side shift the first case body 41 and the second case body 42 from the unlocked state to the locked state. Accordingly, the engaging portion 47a and the engaged portion 89a are arranged to face each other along the sliding direction so that the first case body 41 and the second case body 42 are in a locked state. Sometimes (shown by a solid line in FIG. 27), the engaging portion 47a and the engaged portion 89a are in a direction substantially perpendicular to the plate surface of the main control board 23, that is, the first case body 41 and the second case body 42 are fitted. The first case body 41 and the second case body 42 are engaged with each other in the disengagement direction, and the engagement is released when the first case body 41 and the second case body 42 are in an unlocked state (indicated by a two-dot chain line in FIG. 27). Yes.

  Without properly releasing the sealing by the sealing means 43, the engagement between the engaging claw 70 and the locking portion 82 is forcibly released by, for example, deforming the first case body 41 and the second case body 42, etc. When the main board case 24 is opened, the engaging portion 47a is caught by the engaged portion 89a and is damaged at the low strength portion 49 (FIG. 28), and the wiring 152 disposed on the engaging portion 47a. Is cut at this low strength portion 49. Therefore, for example, even if the first case body 41 and the second case body 42 are connected to each other after that, predetermined error processing such as output of an error warning sound is executed by the error processing unit, so that unauthorized opening is not performed. You can be sure of what happened.

  As mentioned above, although embodiment of this invention was explained in full detail, this invention is not limited to these embodiment, A various change is possible in the range which does not deviate from the meaning of this invention. For example, when the engaging portion 47a is provided integrally with the mounting component on the substrate 23 as in the first embodiment, the mounting component may be, for example, a connector other than the socket 44b for the ROM 44a. Further, the engaging portion 47a may be mounted on the substrate 23 as a dedicated component different from the electronic component.

  When a part of the substrate 23 is used as the engaging portion 47a as in the third embodiment, the damaged engaging portion 47a even if the wiring 152 is not cut when the engaging portion 47a is damaged. From this state, it can be determined whether there has been unauthorized opening in the past.

  Further, as in the third embodiment, error processing executed on condition that the wiring 152 is cut due to damage of the low-strength portion 49 includes warning sound output, warning display by a liquid crystal screen or a lamp, etc. Anything can be used. Further, the wiring 152 may be cut due to the damage of the low-strength portion 49, so that the gaming machine may not operate normally due to, for example, the power supply to the main portion being cut off.
