Description

  The present invention relates to a structure of a board case body for housing a board inside a gaming machine such as a slot machine or a pachinko machine.

  Inside a gaming machine such as a slot machine or pachinko machine, there are a main board for controlling gaming operations, a sub board for controlling the design of the gaming operation display unit according to signals received from the main board, and a lamp Is stored. Since the sub-board may be replaced during maintenance or version upgrade of the gaming machine, it is housed inside the gaming machine so that it can be detached from the main board. For example, a connector is provided on the main board and the sub board, and the main board and the sub board are electrically connected by a wire harness having a connector paired with the connector at both ends. At the time of maintenance or version upgrade of the gaming machine, it is possible to disconnect the sub-board from the main board by removing the connector of the wire harness and the connector on the board.

  By the way, as a situation peculiar to the gaming machine industry, it is necessary to take measures against an act of illegally manipulating the main board or the sub board to illegally operate the gaming machine. For example, the main board and the sub board are individually accommodated in the board case so that they cannot easily contact the board inside from the outside of the board case. The main board or sub board inside the board case is electrically connected by a wire harness via a connector provided on the board case, for example.

Here, in Patent Document 1, a connector is installed on the sub board, a rectangular connector passage hole corresponding to the connector is formed in the board case, and the end of the connector is exposed to the outside of the board case. A substrate case and a substrate are disclosed. The main board and the sub board are connected by electrically connecting the connectors exposed outside the board case with a wire harness. Moreover, in patent document 2, without providing a connector on the control board as a sub board | substrate, the one end part of a wire harness is directly fixed on a control board, and the other end part which has a connector through the hole of a case A substrate case and a substrate drawn out are disclosed. The connector at the end of the wire harness is connected to a connector provided outside the general substrate box that houses the main substrate therein.

  A circuit for illegally altering the signal at the connection between the connector on the board and the connector at the end of the wire harness when the end of the connector connected to the main board or sub board is exposed outside the board case There is a risk that a substrate or the like may be inserted. On the other hand, when the wire harness is fixed to the substrate through the hole of the substrate case, the wire harness must be removed from the substrate when separating the substrate from the substrate case, which is very complicated. Moreover, even if it does not remove a wire harness from a board | substrate, the edge part on the opposite side to the board | substrate fixed side of a wire harness can be passed through the hole of a board case, and a board | substrate and a board case can also be isolate | separated. However, since the hole in the board case must be larger than the size of the connector attached to the wire harness, there is a possibility that the hole may come into contact with the board in the board case.

  The present invention has been made in view of the above-described background, particularly the circumstances of the gaming machine industry, and can easily connect and separate the substrates from each other and can easily separate only the substrate from the substrate case. And it aims at providing a board case with high security.

BEST MODE FOR CARRYING OUT THE INVENTION

  The structure of the substrate case 10 and its accessories according to one embodiment of the present invention will be described.

  As shown in FIG. 1, the substrate case 10 is a box made up of a pair of upper case half 21 and lower case half 31. The upper case half 21 covers and covers the lower case half 31 to form a set of substrate cases 10. The substrate 41 is accommodated so as to be sandwiched between the lower case half 21 and the upper case half 31. The wire harness 51 electrically connected to the substrate 41 is pulled out from between the upper case half 21 and the lower case half 31 to the outside of the substrate case 10. Thus, since the upper case half 21 or the lower case half 31 is not provided with a through-hole and the wire harness is not guided to the outside of the substrate case 10, only the upper case half 21 and the lower case half 31 are separated. Thus, the substrate case 10 and the wire harness 51 can be easily separated. Details of this will be described later. A connector 52 is fixed to an end portion of the wire harness 51 drawn out to the outside of the substrate case 10. The connector 52 can be freely fitted to a connector implanted in a main board (not shown), and can electrically connect the main board and the board 41 in a detachable manner.

  Further, as shown in FIGS. 1 and 2, the upper case half 21 is formed of four substantially continuous upper plates (upper surface walls) 21 a that are substantially rectangular and drooping continuously from the peripheral edge of the upper plate 21 a. It is an integral molded body composed of substantially rectangular side plates (side walls) 21b1, 21b2, 21b3 (not shown), 21b4. In the following description, the longitudinal direction of the side plate 21b1 is the X axis from left to right when viewed from the plane of the paper, the longitudinal direction of the side plate 21b2 is Y axis from the left to the right when viewed from the plane, and the height direction of the side plate 21b1 is the plane of the plane. Each coordinate axis that defines the Z axis from the bottom to the top is defined.

  In the vicinity of the central portion of the bottom end portion of the side plate 21b1, that is, in the vicinity of the central portion of the end portion in the −Z direction, the upper case half body side harness passage portion (first shape) that is a substantially rectangular cut portion with the opening portion directed in the −Z direction. 1 cut-out portion) 22 is formed. At a position spaced in the + Y direction from the upper case half body harness passing portion 22, there is a substantially rectangular parallelepiped pushing plate 23 that hangs down from the upper plate 21 a toward the −Z direction so as to be parallel to and opposite to the side plate 21 b 1. Is formed. A harness locking groove 23 a is formed in the vicinity of the center of the protruding end of the push-in plate (first partition) 23. In addition, two interference prevention portions 24 are provided at positions spaced apart in the + Y direction at the −Z direction end portions of the side plates 21b2 and 21b4 facing each other (refer to FIG. 1 in particular). The interference prevention unit 24 is a substantially rectangular notch with the opening directed in the −Z direction. A screw hole 25 for fixing the upper case half 21 to the lower case half 31 is formed in the vicinity of the interference prevention unit 24.

  The lower case half 31 includes a substantially rectangular lower plate 31a and four continuous substantially rectangular side plates (side walls) formed by standing upright from the end of the lower plate (lower wall) 31a at a right angle in the Z direction. ) 31b1, 31b2, 31b3 (not shown) and 31b4. At the end in the + Z direction of the side plate 31b1, a lower case half body side harness passage part (second cutout part) 32, which is a substantially rectangular notch with the opening directed in the + Z direction, is formed.

  At a position spaced in the + Y direction from the lower case half body side harness passage portion 32, there is a partition wall 33a1 that rises vertically from the lower plate 31a toward the + Z direction in parallel to and opposite to the side plate 31b1. The height of the partition wall 33a1, that is, the length extending from the lower plate 31a in the + Z direction is the length from the lower plate 31a to the lower case half harness passing portion 32, that is, the lower plate 31a of the lower case half harness passing portion 32. It is preferable that it is longer than the height of the lower case half body side harness passage part 32 which is the length up to the part closest to. Further, partition walls 33a2 and 33a3 facing each other are formed to rise parallel to the side plates 31b2 and 31b4 from the lower plate 31a in the + Z direction, and continuously connect the partition walls 33a1 and the side plates 31b1. . Here, the space surrounded by the partition walls (second partition walls) 33 a 1, 33 a 2, 33 a 3 and the side plate 31 b 1 is referred to as a harness storage space 33. In the partition wall 33a2 and the partition wall 33a3, slide grooves 34a and 34b that open toward the harness storage space 33 side, extend in parallel with the Z axis, and face each other are formed.

  From the side plates 31b2 and 31b4, two fixing projections 35 extending in the + X direction and the −X direction are formed at positions spaced apart in the Y direction from the side plates 31b1 and 31b3, respectively (particularly FIG. 1). See). A through-hole for screwing the substrate case 10 to a gaming machine main body (not shown) is formed at the center of the fixing protrusion 35. A screw hole 36 that is a through hole for fixing the upper case half 21 to the lower case half 31 is formed in the vicinity of the + Z direction of the fixing protrusion 35. The lower plate 31a is provided with a substrate mounting projection 37 for fixing the substrate 41 apart from the lower plate 31a.

  The substrate 41 is a substantially rectangular plate-like body. In the vicinity of the four corners, screw holes 42 that are through holes for fixing the substrate 41 to the lower case half 31 with screws are formed. On the substrate 41, one or a plurality of connectors 43 are implanted.

  In particular, referring to FIG. 3, the wire harness 51 has, at one end thereof, for example, a connector 52 that can be fitted to a connector that is implanted on a main board (not shown). The other end of the wire harness 51 has a connector 53 that can be fitted to the connector 43 on the substrate 41.

  Next, a method of using the substrate case 10 according to one embodiment of the present invention will be described with reference to FIGS.

  The substrate 41 is placed on the substrate mounting protrusion 37 of the lower case half 31, and the substrate 41 is fixed to the lower case half 31 with screws. The connector 53 of the wire harness 51 is fitted and connected to the connector 43 on the substrate 41. The wire harness 51 is disposed so as to pass over the harness storage space 33, and the connector 52 of the harness 51 is disposed outside the substrate case 10. The upper case half 21 is combined so as to cover the lower case half 31. At this time, the wire harness 51 is positioned in the harness locking groove 23 a of the push-in plate 23 of the upper case half 21. Both ends of the push-in plate 23 are aligned with the slide grooves 34 a and 34 b, and the upper case half 21 is pushed in close proximity to the lower plate 31 a of the lower case half 31 while sliding on the slide grooves 34 a and 34 b. The side edge of the push-in plate 23 is surrounded by the partition walls 33a1, 33a2, and 33a3 when the upper case half 21 and the lower case half 31 are in the coupled state. At this time, since the harness 51 is guided by the harness locking groove 23a of the push-in plate 23, the harness 51 is not shifted to the outside of the push-in plate 23. In addition, since the push-in plate 23 travels inside the harness housing space 33, the harness 51 does not deviate greatly even if the harness 51 deviates from the harness locking groove 23a. When the upper case half 21 approaches the lower case half 31, the harness 51 is finally sandwiched between the upper case half harness passing portion 22 and the lower case half harness passing portion 32 from above and below. It extends from the inside to the outside.

  Each of the four fixing protrusions 35 of the lower case half 31 is located inside the four interference prevention portions 24 of the upper case half 21. At this time, the end portion of the push-in plate 23 is closer to the lower plate 31 a than the substrate 41. In this state, the upper case half 21 and the lower case half 31 are integrally fixed by inserting the screw 61 into the screw holes 25 and 36.

  When the upper case half 21 and the lower case half 31 are completely combined, the upper case half harness passing portion 22 and the lower case half harness passing portion 32 are spaced apart in the vertical (Z-axis) direction. The harness passage opening is formed. Preferably, the vertical width of the harness passage opening is equal to the thickness of the wire harness. In such a case, it is difficult to insert a foreign object such as a tool from the harness passage opening. Even if the foreign matter can be inserted, the push plate 23 and the partition walls 33a1, 33a2, and 33a3 of the harness storage space 33 are present, and the foreign matter cannot reach the substrate. That is, since the obstacle is provided on the line connecting the harness passage opening and the substrate 41, the substrate 41 cannot be easily accessed from the harness passage opening.

  Here, when the wire harness 51 has a certain thickness, there are cases where it cannot be bent inside the harness housing space 33. In such a case, even if there is no push-in plate 23, at least the partition wall 33a1 exists on a straight line that crosses the harness passage opening and the board 41, so that the board 41 cannot be easily accessed from the harness passage opening. is there. As described above, in particular, when the height of the partition wall 33a1 is higher than the height of the lower case half body side harness passage portion 32, the board 41 cannot be easily accessed from the harness passage opening.

  At the time of maintenance or upgrading of the gaming machine, the upper case half 21 can be separated from the lower case half 31 by removing the screw 61. Further, the substrate 41 can be separated from the lower case half 31 together with the wire harness 51 simply by removing the screws for fixing to the lower case half 31.
