By sliding on a guide groove (not shown), the sliding guide portion 505 and the sliding of the sliding member 500 are guided.

  Next, with reference to FIG. 21 and FIG. 22, an assembly process (particularly, mounting of the cover member 400) of the main control board case 55 that constitutes the main control board unit according to the second embodiment will be described. FIG. 21 is a schematic cross-sectional view of the main control board unit, showing the state where the sliding member 500 is in the first position. More specifically, it is viewed from the Z direction shown in FIGS. 15 to 17. It is a figure which shows the cross section in a case. 22 is a schematic cross-sectional view of the main control board unit, showing the state in which the sliding member 500 is in the second position, and showing the cross-sectional view when seen from the same direction as FIG. 21. is there. 21 and 22, a portion surrounded by a vertical line shows a cross section of the upper case member 261a, a portion surrounded by a horizontal line shows a cross section of the lower case member 261b, and a portion surrounded by a slanted line is a cover. The cross section of the member 400 is shown, and the blackened portion shows the cross section of the sliding member 500. In addition, the arrow in FIG. 22 indicates that the sliding member 500 has moved from the first position to the second position.

  In the main control board unit according to the second embodiment, first, with the main control board 71 and the sliding member 500 accommodated, the upper case member 261a and the lower case member 261b are fitted to each other, and the third sealing portion 265 is formed. An inter-case fixing screw 267 is screwed to fix the upper case member 261a and the lower case member 261b together, and then a sealing seal 266 is provided on the back surface of the cover surface of the cover member 400 so as to cover at least the third sealing portion 265. Stick on the side.

  Next, the cover member 400 to which the seal seal 266 is attached is attached to the case body 261. At this time, although the restriction portions 402 (402a, 402b) are locked to the upper case member 261a and the upward movement of the cover member 400 is temporarily restricted, the elasticity of the cover member 400 causes the cover member 400 to move to the case. It is still in a detachable state with respect to the main body 261.

  Next, the sliding screw 404 is screwed into the screw screw insertion portion 501 on the screw insertion hole 311 side through the screw insertion hole 311 to fix the screw, and the sliding screw 405 is screwed through the screw insertion hole 312. It is screwed into the screw screw insertion portion 501 on the insertion hole 312 side and screwed. As a result, the sliding member 500 moves from the first position to the second position, and the lower case member 261b and the sliding member 500 are fixed.

  Here, on the sliding surface inside the upper case member 261a located above, the upper case side recess is formed in the Z direction (that is, the lateral direction when viewed from the X direction or the Y direction) shown in FIGS. 601 (601a, 601b) are provided, and when the sliding member 500 moves to the second position, the inclined surface portion of the locking portion 503a enters the upper case side recess 601 and the corner of the upper case side recess 601 engages. The locking part 503a is locked in the upper case side recessed part 601 (601a, 601b) by entering the inner corner formed by the vertical surface of the stop 503a and the rib.

  In addition, on the sliding surface inside the lower case member 261b located below, the lower case side recess 602 extends in the Z direction shown in FIGS. 15 to 17 (that is, the lateral direction when viewed from the X direction or the Y direction). (602a, 602b) are provided, and when the sliding member 500 moves to the second position, the sloped portion of the locking portion 503c enters the lower case side recess 602 and the corner of the lower case side recess 602 locks. The locking portion 503c is locked in the lower case side concave portion 602 (602a, 602b) by entering into the inner corner formed by the vertical surface of the portion 503c and the rib.

  Although not shown in FIGS. 21 and 22, the sliding surface on the inner side of the lower case member 261b located laterally has a direction perpendicular to the Z direction shown in FIGS. , The lower case side concave portion is provided over the X direction or the vertical direction when viewed from the Y direction (hereinafter, for convenience, the lower case side concave portion provided on the sliding surface on the left side when viewed from the X direction is referred to as the lower case. Side recesses 603, and the lower case side recesses provided on the sliding surface on the right side when viewed in the X direction are referred to as lower case side recesses 604.) When the sliding member 500 moves to the second position, the locking portion 503b moves. The slanted surface portion enters the lower case side recessed portion 603, and the corner of the lower case side recessed portion 603 enters the inner angle formed by the vertical surface of the locking portion 503b and the ribs, so that the locking portion 503b extends. Locked in. Further, the slanted surface portion of the locking portion 503d enters the lower case side recessed portion 604, and the corner of the lower case side recessed portion 604 enters the inner angle formed by the vertical surface of the locking portion 503d and the ribs. 503d is locked in the lower case side recess 604.

  That is, when the sliding member 500 moves to the second position, each of the locking portions 503a, 503b, 503c, 503d causes the upper case side recess 601, the lower case side recess 602, the lower case side recess 603, and the lower case side recess. The sliding member 500 is locked by 604 and cannot be moved from the second position.

  The upper case member 261a may be located on the side of the sliding member 500, and in this case, the lower case side recessed portion 603 and the lower case side recessed portion are formed on the sliding surface inside the upper case member 261a. 604 (in other words, the upper case side recess 603 and the upper case side recess 604) may be provided.

  Further, the shapes of the locking portions 503a, 503b, 503c, 503d are not limited to those described above, and can be slid with respect to the upper case side recess 601, the lower case side recess 602, the lower case side recess 603, and the lower case side recess 604. Any shape can be adopted as long as the moving member 500 is locked so as to be immovable from the second position.

  Further, instead of the upper case side concave portion 601, the lower case side concave portion 602, the lower case side concave portion 603, and the lower case side concave portion 604, the upper case side convex portion is provided on the sliding surface inside the upper case member 261a, A lower case side convex portion may be provided on each of the sliding surfaces inside the 261b. In this case, the shapes of the locking portions 503a, 503b, 503c, 503d are set so that the sliding member 500 is immovable from the second position with respect to the upper case side convex portion and the lower case side convex portion. The shape should be stopped.

  21 and 22, the screw insertion holes 311 and 312 are provided on the left side and the right side of the lower case member 261b, respectively, but the invention is not limited thereto. For example, the screw insertion holes 311 and 312 may be provided below the lower case member 261b in FIGS. 21 and 22. In this case, the arrangement of the screw screw insertion portion 501 may be changed according to the positions of the screw insertion holes 311 and 312, and the configuration of the sliding member 500 may be changed appropriately. In this case, the upper side in FIG. 21 and FIG. 22 (that is, the cover member 400 side) is the first position of the sliding member 500, and the lower side in FIG. 21 and FIG. 22 (that is, the screw insertion holes 311 and 312 are The side (provided) may be configured to be the second position of the sliding member 500.

  When the sliding member 500 moves to the second position, the protruding piece 504 is inserted into the insertion portion 403, and the cover member 400 and the sliding member 500 are engaged with each other. Here, since the sliding member 500 is locked by the locking portion 503 so as to be immovable from the second position, even if the sliding screw 404 or 405 is loosened, the sliding member 500 slides with the cover member 400. The engagement with the moving member 500 will not be released.

  At this time, the surface of the cover member 400 on which the restricting portions 402 (402a, 402b) and the insertion portions 403 (403a, 403b) are provided is outside (that is, the surface of the sliding member 500 on which the protruding piece 504 is provided). , Is biased in the Y direction on the side on which the regulation portion 402a and the insertion portion 403a are provided, and in the X direction on the side on which the regulation portion 402b and the insertion portion 403b are provided. Therefore, the restricting portion 402 (402a, 402b) is completely locked to the upper case member 261a, and the upward movement of the cover member 400 is restricted.

  Therefore, when the case main body 261 is to be opened thereafter, a part of the sealing seal 266 is broken from the through hole 401 to remove the inter-case fixing screw 267, and the upper case member 261a together with the cover member 400 together with the lower case member 261b. Since it is necessary to separate the case body 261 from the above, the trace of the case body 261 will surely remain due to the breakage of the seal 266.

  As described above, according to the substrate case according to the second embodiment, the cover member 400 can be fixed to the case body 261 only by screwing the sliding screws 404 and 405, and thus the sealing seal 266 is covered. Even when the cover member 400 is provided, the assembly can be easily performed.

  Further, according to the substrate case of the second embodiment, when the sliding screws 404 and 405 are screwed, the sliding member 500 moves from the first position to the second position and then cannot move from the second position. Becomes As a result, it becomes extremely difficult to remove the cover member 400, which makes it more difficult to access the sealing seal 266.

  Further, according to the board case of the second embodiment, when the sliding member 500 moves to the second position, the protruding piece 504 is inserted into the insertion portion 403 accordingly, and the cover member 400 and the sliding member 500 are separated from each other. Are engaged. Therefore, the removal (movement) of the cover member 400 can be restricted with a simple configuration.

  Further, according to the board case of the second embodiment, the removal (movement) of the cover member 400 is also restricted by the restriction part 402 when at least the sliding member 500 is in the second position. Therefore, the removal (movement) of the cover member 400 can be more firmly regulated.

  Further, according to the substrate case of the second embodiment, when the sliding member 500 moves to the second position, it becomes extremely difficult to access the third sealing portion 265 without going through the through hole 401. Therefore, the trace of the sealing seal 266 is surely left due to the breakage of the sealing seal 266, so that even if the third sealing portion 265 is accessed, it can be easily found.

  The gaming machine according to the present embodiment and the board cases according to the first embodiment and the second embodiment of the present embodiment provided in the gaming machine have been described above, but these embodiments are presented as examples. However, it is not intended to limit the scope of the invention. These embodiments can be implemented in various other forms, and various omissions, combinations, replacements, and changes can be made without departing from the spirit of the invention.

  For example, in the present embodiment, the pachi-slot machine 1 is described as an example of the gaming machine, but the gaming machine is not limited to this, and a pachinko machine may be adopted as the gaming machine. In a pachinko machine, a game board is attached to a frame, and a front door made of a transparent material is attached to the front side of the pachinko machine so as to be openable and closable.
