  And the 2nd sealing means 57 provided in the edge part on the opposite side to the hinge means 56 is the sealing part 57a by the side of the 2nd case body 55, and the removal prevention part 57b by the side of the 1st case body 54. The first case body 54 and the second case body 55 are connected by detachably engaging a sealing pin (not shown) accommodated in the sealing portion 57a to the separation preventing portion 57b. It can be sealed inseparably.

  On the back wall 62 side of the second case body 55, a connector recess 63 that is recessed into the main control board 13 side, and a bulging portion 64 that is formed in an outward bulging shape are provided. The connector recesses 63 are disposed, for example, on the left and right ends of the back wall 62 corresponding to the connectors 41 disposed in the vicinity of the outer edge of the main control board 13, and the bottom surfaces 63 a abut against the surface of the main control board 13. A plurality of connector holes 65 for exposing the connector 41 on the main control board 13 side are formed so as to correspond to, for example, each connector 41.

  The bulging portion 64 includes a bulging portion back surface 66 that faces the surface of the main control board 13, and a bulging portion side wall 67 that surrounds the outer periphery of the bulging portion back surface 66. The bulging portion side wall 67 is common to, for example, a part of the peripheral wall 61 of the second case body 55 and a part of the side wall of the connector recess 63.

  As shown in FIGS. 3 to 8, the bulging portion rear surface 66 has a ROM recess (recessed on the ROM 42 a side at a position corresponding to the ROM 42 a among various electronic components 42 provided on the main control board 13. An extraction preventing portion 71 is formed. For example, the bottom wall 72 of the ROM recess 71 is formed in a rectangular shape having substantially the same size as the ROM 42a.

  The ROM 42a is detachably attached to the socket 43 fixed to the main control board 13, and the ROM recess 71 has a gap between the bottom wall 72 and the ROM 42a so that the ROM 42a cannot be removed. It is formed to a certain depth.

  Furthermore, a plurality of, for example, four ribs 74 a to 74 d are provided on the bulging portion back surface 66 so as to connect the peripheral wall 73 of the ROM recess 71 and the bulging portion side wall 67 along the inner surface side. ing. These ribs 74a to 74d are two surfaces 73a and 73b that are closer to the bulging portion side wall 67 among the four surfaces constituting the peripheral wall 73, and the bulging portion side walls facing the two surfaces 73a and 73b. One or a plurality of, for example, two, are arranged between 67a and 67b.

  Each of the ribs 74a to 74d has a flat plate shape and intersects the peripheral wall 73 and the bulging portion side wall 67 substantially perpendicularly, and ribs 74a and 74b and the peripheral wall disposed between the peripheral wall 73a and the bulging portion side wall 67a. The ribs 74c and 74d arranged between 73b and the bulging portion side wall 67b are arranged in parallel to each other.

  Each of the ribs 74a to 74d is formed so that, for example, its standing height is substantially the same as the depth of the ROM recess 71. The heights of the ribs 74a to 74d need not be the same as the depth of the ROM recess 71, but are as close as possible to the surface of the main control board 13 as long as they do not interfere with the electronic components 42 on the main control board 13 side. It is desirable to extend to.

  As described above, the ROM concave portion 71 that is adjacent to the ROM 42a with a gap in which the ROM 42a cannot be removed is disposed on the bulging portion back surface 66, which is the opposed surface of the ROM 42a, in the main control board case 14, and the bulging portion. Since the ribs 74a to 74d that connect the bulging portion side wall 67 that surrounds the back surface 66 and the ROM concave portion 71 are integrally provided, for example, the bulging portion rear surface 66 is cut out in a range including the ROM concave portion 71. Even in this case, the ribs 74a to 74d are obstructed and cannot be cut out at least in a short time. For example, even if a portion where the ROM recess 71 and the ribs 74a to 74d are not formed is cut out, the ROM 42a cannot be extracted because the ROM recess 71 is close to the ROM 42a.

  As described above, the slot machine according to the present embodiment makes it difficult to execute the goto action of hollowing out a part of the main control board case 14 and exchanging the ROM 42a, thereby effectively preventing the occurrence of the goto action.

  9 to 11 illustrate the second embodiment of the present invention, and show an example in which the ROM recess 71 is provided in a narrower range than the outer shape of the ROM 42a.

  As shown in FIGS. 9 to 11, in this embodiment, as in the first embodiment, a ROM recess (extraction preventing portion) 71 is provided so as to correspond to the ROM 42 a, and the peripheral wall 73 of the ROM recess 71 and A plurality of ribs 74a to 74d are provided so as to connect to the bulging portion side wall 67, but the bottom wall 72 of the ROM recess 71 is formed smaller than the outer shape of the ROM 42a.

  Since the bottom wall 72 of the ROM recess 71 is close to the ROM 42a, it is considered difficult to cut out the bottom wall 72 without damaging the main control board 13 side. However, the bottom wall 72 of the ROM recess 71 is temporarily cut out. Even if it is possible, in the case of the present embodiment, the size of the opening formed thereby is smaller than that of the ROM 42a, and it is difficult to replace the ROM through the opening. The occurrence of fraud can be prevented more effectively than in the case of the embodiment.

  12 to 14 exemplify the third embodiment of the present invention, in which the ROM recess 71 in the first and second embodiments is omitted and a part of the ribs 74a to 74d is used as an extraction preventing portion. Show.

  As shown in FIGS. 12 to 14, the main control board case 14 of the present embodiment faces at least the ROM 42 a from the bulging portion side wall 67 on the inner surface side of the bulging portion back surface 66 on the second case body 55 side. A plurality of, for example, four ribs 74a to 74d are disposed up to the position.

  A ROM facing portion 74 ', which is a portion facing the ROM 42a in the ribs 74a to 74d, constitutes an example of an extraction preventing portion, and the ROM facing portion 74' cannot extract the ROM 42a from the ROM 42a. Close to each other with a gap. The ribs 74a and 74b and the ribs 74c and 74d are arranged in directions orthogonal to each other so as to be substantially parallel to the bulging portion side wall 67b and the bulging portion side wall 67a, and are connected to each other at the ROM facing portion 74 '. ing.

  Further, in the ROM facing portion 74 ′, the area surrounded by the ribs 74 a to 74 d is smaller than the outer shape of the ROM 42 a.

  As described above, it is not always necessary to form the extraction preventing part in a recessed shape, and even if a part of the ribs 74a to 74d is used as the extraction preventing part, substantially the same effect as in the first and second embodiments can be expected. .

  15 to 17 illustrate a fourth embodiment of the present invention, and show an example in which ribs are provided corresponding to substantially the entire circumference of the extraction preventing portion 71.

  On the inner surface side of the bulging portion rear surface 66, an intermediate rib 74i is erected on the opposite side to the bulging portion side wall 67a with respect to the ROM recess 71, and an intermediate rib 74j is erected on the opposite side to the bulging portion side wall 67b. The bulging portion side wall 67b, the intermediate rib 74i, the intermediate rib 74j, and the bulging portion side wall 67a are connected to each other and surround the ROM recess 71.

  Further, between the peripheral walls 73a to 73d of the ROM recess 71 and the bulging portion side wall 67a, the bulging portion side wall 67b, the intermediate rib 74i, and the intermediate rib 74j that oppose them, respectively, are connected to each other. One or a plurality of, for example, two connecting ribs 74 a to 74 h are provided on the inner surface side of the bulging portion back surface 66.

  As described above, it is desirable that the ribs connecting the extraction preventing portions 71 and 74 'and the bulging portion side wall 67 are arranged evenly on substantially the entire circumference of the extraction preventing portions 71 and 74' as much as possible. At this time, for example, when the distance between the extraction preventing portions 71 and 74 'and the bulging portion side wall 67 facing the extraction preventing portions 71 and 74' is large, the connecting ribs 74e to 74h arranged in the direction are separated from each other. The intermediate ribs 74i and 74j may be connected to a nearby bulging portion side wall 67. As described above, the ribs 74a to 74j may be provided so as to directly or indirectly connect the extraction preventing portions 71 and 74 ′ and the bulging portion side wall 67.

  FIG. 18 illustrates the fifth embodiment of the present invention, and shows an example in which the first embodiment is modified and a metal plate is mounted along the inner surfaces of the ribs 74a and 74b and the bulging portion back surface 66. ing.

  In FIG. 18, the metal member 81 includes a pair of first flat plate portions 82 and 82 disposed along both surfaces of the ribs 74a and 74b, and the pair of first flat plate portions 82 and 82 on one end side of the ribs 74a and 74b. And a second flat plate portion 84 for connecting the first flat plate portion 82 on the rib 74a side and the first flat plate portion 82 on the rib 74b side along the inner surface side of the bulging portion back surface 66. For example, the ribs 74a and 74b are sandwiched between the pair of first flat plate portions 82 and 82, for example, by press-fitting, so that the main control board case 14 is detachably mounted.

  As described above, by mounting the metal plate along the rib 74a and the inner surface side of the bulging portion back surface 66, it becomes more difficult to cut out the main control board case 14, and there is an advantage that the anti-fraud effect is greatly improved. is there.

  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 ROM concave portion 71 as an example of the extraction preventing portion does not have to have a rectangular bottom wall 72, and may have any shape such as a circle or an ellipse. A ROM recess 71 may be provided. Further, the extraction preventing portion may be provided in a columnar shape or other protrusion shape on the inner surface side of the bulging portion back surface 66.

  The ribs 74a to 74j may be arranged so as to connect between the side wall 67 and the extraction preventing portions 71 and 74 ′ through an arbitrary path other than a straight line such as a meandering shape or a zigzag shape.

  In the fifth embodiment, an example in which a metal plate is mounted on the inner surfaces of the ribs 74a and 74b and the bulging portion back surface 66 is shown. However, if a metal plate is mounted on the bulging portion back surface 66, Since the visibility is lowered, as shown in FIG. 19, the second flat plate portion 84 along the bulging portion back surface 66 may be omitted, and the metal member 81 may be attached only to the ribs 74a and 74b. Good.

  The metal plate may be attached to all the ribs 74a to 74d, etc., or may be attached only to any one or more of them, or the metal plate is not attached to the rib 74a, You may attach a metal plate only to the inner surface side of the bulging part back surface 66. FIG. Further, a metal plate may be mounted along at least one of the bottom wall 72 and the peripheral wall 73 of the ROM recess 71. When a metal plate is mounted on the rib 74a or the like, it may be mounted only on one side. The metal plate may be attached by any method such as sticking or screwing.

  In the embodiment, an example in which the present invention is applied to a slot machine has been described. Needless to say, the present invention can be similarly applied to various gaming machines such as a pachinko machine and an arrange ball machine.
