A fitting rib 146 that can be fitted to the inside of the surrounding rib 108 on the fixed base portion 106 side, and a protruding portion on the same side as the fitting rib 146 from the sealing cover plate 145 corresponding to both sides of the sealing member 92 in the arrangement direction. It is comprised with the partition rib 147 made.

  The sealing cover plate 145 is provided with a plurality of operation holes 148 corresponding to the pressed portions 114 of the respective sealing members 92, the crimping pins 107 on the second fixed base portion 106 side, and fitting ribs 146. A plurality of recesses 149 that are recessed on the same side are provided, and insertion holes 150 for the caulking pins 107 are respectively formed in the recesses 149.

  Further, on the outer edge side of the second fixing portion 132, a breakage notch 151 extending from the fitting rib 146 to the sealing cover plate 145 is provided at a position corresponding to the first breakage portion 121, for example.

  The connecting portion 133 is, for example, a flat plate having sufficient flexibility, and integrally connects the cover plate 141 on the first fixing portion 131 side and the sealing cover plate 145 on the second fixing portion 132 side. The first case body 41 and the second case body 42 are formed so as not to obstruct the opening and closing.

  The first fixing portion 131 and the second fixing portion 132 of the connecting member 44 are fixed to the first fixing base portion 103 and the second fixing base portion 106 by heat caulking, respectively, in the following procedure. That is, first, the first and second fixing portions 131 and 132 are fitted inside the surrounding ribs 105 and 108 while the fitting ribs 142 and 146 are inserted into the respective insertion holes 144 and 150 while the caulking pins 104 and 107 are inserted. Are attached to the first and second fixed base portions 103 and 106 (FIG. 13 (a) → (b)), and then the crimping pins 104 and 107 are crushed while being heated by a predetermined heat caulking tool 152. (FIG. 13 (b) → (c)), the first and second fixing portions 131 and 132 are fixed to the first fixing base portion 103 and the second fixing base portion 106, respectively.

  As a result, the first case body 41 and the second case body 42 are connected inseparably, and the sealing member 92 on the second case body 42 side is pressed as shown in FIGS. The substantially entire portion excluding the portion 114 is covered from the outside by the second fixing portion 132 on the connecting member 44 side.

  Moreover, the coupling | bonding and sealing of the 1st case body 41 and the 2nd case body 42 which were connected by this connection member 44 are performed in the following procedures. That is, first, the main control board 23 is mounted inside the second case body 42, and the pair of engaging protrusions 58 on the second case body 42 side is extended along the guide grooves 78 and 79 on the first case body 41 side. After being inserted into the engaged hole 87 from the inside, the engaging claw 70 on the second case body 42 side is fitted into the notch portion 81 on the first case body 41 side to fit in the unlocked state (FIG. 17 → FIG. 18).

  At this time, 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, for example, its side wall 116a. , 116b is in a state of being fitted into the notch 102 of the side wall 72 on the first case body 41 side.

  Then, the second case body 42 and the first case body 41 are slid relative to each other in the direction in which the right peripheral wall 54 and the right fitting wall 75 are brought closer to each other, and the engaging claw 70 on the second case body 42 side is obtained. Is engaged with the locking 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 (FIG. 18 → FIG. 19). Thereby, 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, the tip of a tool such as a screwdriver is applied to the concave portion 114a of the pressed portion 114 of the sealing member 92 from the outside of the second fixed portion 132 through the operation hole 148, and pressed toward the inside, that is, the first case body 41 side. To do. As a result, the holding portion 115 is damaged and the sealing member 92 is separated from the second case body 42, and the coupling portion 113 on the distal end side of the sealing member 92 pushes the elastic engagement portion 97 to both sides. It fits in the insertion slit 95. 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. 20).

  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 first case body 41 side restricts the relative movement in the opening direction of the second case body 42 via the contact portion 124, the main substrate case 24 is opened as it is. I can't.

  Further, in the state where the main substrate case 24 is sealed by the sealing means 43 in this way, the sealing member 92 used for the sealing is separated from the second case body 42. The high-wall opening 101a in which 92 is disposed is in a state of being greatly opened, but as shown in FIG. 14 and the like, the high-wall opening 101a is substantially covered by the second fixing part 132, so It is difficult to perform an illegal act such as forcibly releasing the coupling of the sealing member 92 to the coupled portion 91 through the high wall opening 101a.

  For example, even if the main board case 24 is opened with no trace left on the second case body 42 and the sealing member 92 by damaging a part on the first case body 41 side, for example, Since the case body 41 and the second case body 42 are connected by the connecting member 44, the damaged first case body 41 cannot be separated from the second case body 42 unless the connecting member 44 is cut. Therefore, it is impossible to replace the damaged first case body 41 with a duplicate product and restore the main board case 24 to the same state as before opening without leaving a trace, and such an illegal act is effective. Can be prevented.

  When the main substrate case 24 is normally 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. Then, as shown in FIG. 21A, the unsealing obstruction part 93 is separated from the second case body 42 and removed. Thereby, the standing wall opening 101b and the low wall opening 101c are opened, and the portion restricted by the sealing member 92 when the second case body 42 is slid in the unlocking direction with respect to the first case body 41 is provided. Since it disappears (FIG. 21B), the main board case 24 can be opened. When the first damaged portion 121 is cut, the tip side of a nipper or the like is inserted into the notch 151 for damage provided on the second fixing portion 132 side corresponding to the first damaged portion 121. The 1 damaged part 121 can be easily cut.

  The main board case mounting portion 31 to which the main board case 24 described above is mounted includes a mounting opening 161 provided on the back side of the ball collecting case 22 and its mounting opening as shown in FIGS. 161, mounting rails 162 arranged along both upper and lower edges, first support means 163 for supporting one end of the main board case 24, and second support means 164 for supporting the other end of the main board case 24. A sealing cover 165 that covers at least a part of the first and second damaged parts 121 and 122 from the outside of the main substrate case 24 is provided.

  The mounting opening 161 is formed in a substantially rectangular shape corresponding to the main board case 24, and mounting rails 162 extend inwardly along the upper and lower edges.

  The first support means 163 supports one end side, for example, the left end side, of the main substrate case 24, and is configured by a recess that can be engaged with the projecting portion 84 on the main substrate case 24 side. Is provided on the left end side of the mounting opening 161.

  The second support means 164 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 engaging position that engages the protruding portion 85 on the main board case 24 side. The fastening knob can be switched to a position, and is provided on the right end side of the mounting opening 161 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 162, and is first protruded on the left end side. The protrusion 84 may be locked by fitting the portion 84 to the first support 163 and then switching the second support 164 from the release position to the engagement position.

  The sealing cover 165 is integrally provided on the rear side of the main substrate case mounting portion 31 so as to cover the end portion on the sealing region 24b side of the main substrate case 24 mounted on the main substrate case mounting portion 31. A cover plate portion 166 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, 53 on the main substrate case 24 side, and a side wall 72 on the left end side. A connecting plate portion 167 for connecting the edge portion of the cover plate portion 166 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 166 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 portion 166 is transparent so that the sealing cover 165 can visually recognize the sealed / unsealed state by the sealing means 43 from the outside.

  Thus, since the first and second damaged parts 121 and 122 are covered with the sealing cover 165 when the main board case 24 is attached to 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 164 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, in the pachinko machine according to the present embodiment, the first and second fixing portions 131 and 132 on both ends are fixed to the first case body 41 and the second case body 42 in a non-detachable manner, respectively. Since the connecting member 44 that connects the first case body 41 and the second case body 42 in an openable / closable state is provided, for example, by damaging a part of the first case body 41 side, the second case body 42 is damaged. Even if the main board case 24 is opened with no trace left on the sealing member 92, the damaged first case body 41 is separated from the second case body 42 unless the connecting member 44 is cut. I can't. Therefore, it is impossible to replace the damaged first case body 41 with a duplicate product and restore the main board case 24 to the same state as before opening without leaving a trace, and such an illegal act is effective. Can be prevented.

  Further, the sealing means 43 is integrally formed on the second case body 42 side via the first and second damaged portions 121 and 122 and is damaged by damaging the first and second damaged portions 121 and 122. Unsealable portion 93 that can be removed from the case body 42, and provided on the second case body 42 side and separated from the second case body 42 side when pushed in a predetermined direction and cannot be detached to the first case body 41 side A sealing member 92 coupled to the first case body 41 when the sealing member 92 is coupled to the first case body 41 side. Since the movement is restricted and the main substrate case 24 is prevented from being opened, the sealing member 92 constituting the sealing means 43 can be formed integrally with the second case body 42, thereby Minimize parts count and cost While there is an advantage that reduction is possible, it is easy to break and open a part on the first case body 41 side without leaving any trace on the second case body 42 and the sealing member 92. Therefore, connecting the first case body 41 and the second case body 42 with the connecting member 44 is more effective in preventing fraud.

  Further, the sealing member 92 is integrally formed on the second case body 42 side via the holding portion 115, and the second fixing portion 132 on the second case body 42 side in the connecting member 44 is the sealing member 92. Since the operation hole 148 corresponding to the pressed part 114 of the sealing member 92 is provided in the second fixing part 132 so as to cover the outer side from the outer side, The opening formed in the portion where the sealing member 92 is disposed is substantially blocked by the second fixing portion 132, and the coupling of the sealing member 92 to the coupled portion 91 is forcibly released from the outside through the opening. Etc. can be prevented.

  In addition, since the second fixing portion 132 on the second case body 42 side is fixed to the second case body 42 by, for example, heat caulking at a plurality of locations including both sides of each sealing member 92, each sealing member 92 is It can be strictly covered individually.

  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, the connecting member 44 may be fixed to the first case body 41 and the second case body 42 by a method that cannot be removed by a method other than damage. Good. Moreover, you may connect the 1st case body 41 and the 2nd case body 42 mutually by the flexible connection means 44 integrally formed in them.

  The substrate case to which the present invention is applicable is not limited to the configuration shown in the embodiment, and is configured by first and second case bodies that can be fitted together with the substrate interposed therebetween. What is necessary is just to be able to seal a case body with a sealing means.
