It is possible. In addition, since the spacer member 200 is made of a transparent material, even if an unauthorized part (such as an unauthorized board) is disposed inside the spacer member 200, it can be easily detected. Further, in the accommodating part 210, the wall part in which the opening part 212 is formed (that is, the game board side wall part 218) is constituted by a transparent member, and the accommodating part is interposed through the wall part in which the opening part 212 is formed. The inside of 210 is visible. As shown in FIGS. 22 and 24, the shape on the game board side of the spacer member 200 is formed so as to correspond to the unevenness of the base member 70 and the unevenness of various parts (that is, a plurality of shapes corresponding to these). Ribs and the like are formed), and it is considered that no extra space is generated between the spacer member 200 and the base member 70 or parts in the vicinity of the base member 70.

  As shown in FIGS. 19 to 24, in the housing portion 212, an opening portion 212 is formed in the game board side wall portion 218, and the reserve screw 240 can be taken out from the opening portion 212.

  The opening 212 is arranged at an end position close to one side of the pair of side wall parts 213 and 214 in the accommodating part 210 (that is, an end position close to the side wall part 214 side). As shown in FIGS. 21, 22, and 23, the opening 212 is formed in a form in which the wall surface of the bottom wall 216 continues into the opening region of the opening 212. As shown in FIG. 24, when viewed from the game board side, the holding position of the reserve screw 240 is a position that is out of the opening area of the opening 212. That is, when viewed from the game board side, the reserve screw 240 cannot be viewed through the opening 212. Therefore, even if any tool is inserted from the opening 212, it is difficult to reach the reserve screw 240, and it is difficult to remove the reserve screw from the opening side.

  As described above, according to the configuration of the present embodiment, the first connecting part 111a and the second connecting part 121a can be removed by breakage. The inside can be opened, and the opened trace remains. Further, when closing again, the spare screw 240 can be easily accessed, and can be easily closed as long as the spare screw 240 is fixed to the spare connecting portion. That is, it is possible to realize a substrate case unit that is easy to perform regular maintenance and has excellent crime prevention.

  Further, the case member 120 is configured to be openable and closable with respect to the base member 70, and the temporary holding portion 130 is formed on the opposing wall surface 115 that faces the base member 70 when the case member 120 is closed. The temporary holder 130 and the reserve screw 240 do not get in the way at the time (that is, when the case member 120 is closed), and the case member 120 is opened and closed when performing the closing operation using the reserve screw 240. Thus, the temporary holding unit 130 can be easily accessed.

  Further, since the temporary holding portion 130 of the case member 120 is arranged at a predetermined distance from the outer surface of the base member, there is a space for arranging the screw portion of the auxiliary screw 240 between the temporary holding portion 130 and the outer surface of the base member. It is formed. Since the preliminary screw 240 is temporarily held in a state where the screw portion 244 is extended to the spacer member 200 side, the preliminary screw 240 can be temporarily held without enlarging the temporary holding portion 130.

  The temporary holding unit 130 includes a hole formed in the wall surface of the holding member 110 and a plurality of elastic pieces 150 formed in a cantilever shape toward the center of the hole in the wall surface of the holding member 110. The spare screws 240 are temporarily held by engaging the plurality of elastic pieces 150 and the spare screws 240. Therefore, the structure which hold | maintains the reserve screw 240 with a part of wall surface of the holding member 110 is implement | achieved suitably, and simplification of an apparatus structure and cost reduction are achieved effectively.

  The preliminary screw 240 is constituted by a breaking screw, and the temporary holding part 130 is constituted by a plurality of elastic pieces 150 whose tip is interposed between the tool engaging part 241 and the fastening part and is opposed to the breaking part 246. Has been. Therefore, this is a preferred example in which the temporary holding can be released with an appropriate force while the preliminary screw 240 is stably temporarily held.

  In the temporary holding portion 130, a first guide wall 153 capable of supporting the outer peripheral surface 241a of the tool engaging portion 241 and a second guide wall 155 capable of supporting the outer peripheral surface 243a of the head portion 243 of the fastening portion 242 are provided. ing. Therefore, the swinging of the auxiliary screw 240 can be reduced or prevented, and problems caused by the swinging (such as detachment of the preliminary screw 240) can be effectively prevented.

  In the present embodiment, the case member 120 cannot be removed unless the connection between the first connecting portion 111a and the second connecting portion 121b is released by breaking. The first sealing portion 129a provided on the case 120a side and the second sealing portion 129b provided on the second case 120b side are sealed by the sealing member 128, and the case member 120 is destroyed. The inside of the case member 120 cannot be accessed unless a predetermined part (part near the sealing member 128) is broken. Therefore, it has a double crime prevention function and it is extremely difficult to access the control board.

  In this embodiment, the temporary holding unit 130 includes a first temporary holding unit 131, a second temporary holding unit 132, and a third temporary holding unit 133. The second temporary holding part 132 is arranged side by side, and the elastic piece 150 of the first temporary holding part 131 and the second temporary holding part 132 in the direction perpendicular to the arrangement direction (that is, the vertical direction). It arrange | positions so that the elastic piece 150 may overlap. Therefore, the space in the arrangement direction can be effectively reduced. Similarly, the second temporary holding unit 132 and the third temporary holding unit 133 are arranged side by side (more specifically, the first temporary holding unit 131, the second temporary holding unit 132, the third temporary holding unit 132, The temporary holding portions 133 are arranged side by side), and the elastic piece 150 of the second temporary holding portion 131 and the elastic piece 150 of the third temporary holding portion 132 in a direction orthogonal to the arrangement direction (that is, the vertical direction). And are arranged so as to overlap.

  Furthermore, since the accommodating portion 210 is disposed adjacent to the temporary holding portion 130, when the auxiliary screw 240 is taken out, an operation from the case member 120 side (for example, an extruding operation for extruding the auxiliary screw 240, a temporary operation, The holding by the temporary holding unit 130 can be released by a deforming operation or the like for deforming the holding unit 130, and can be temporarily stored in the storage unit 210. Accordingly, it is difficult to perform an unauthorized operation, and a regular take-out operation can be easily performed.

  In addition, since the spacer member 200 is arranged between the holding member 110 and the game board 7, it is possible to prevent an unauthorized part (for example, an unauthorized board) from being installed therebetween. Further, since the spacer member 200 is also used as the accommodating portion 210, the structure is excellent in terms of cost.

  In addition, since the spacer member 200 is made of a transparent material and the preliminary screw 240 held by the temporary holding unit 130 via the spacer member 200 is visible, the user holds the temporary holding unit 130 on the temporary holding unit 130. The number of spare screws 240 thus made can be easily confirmed.

  Furthermore, since the box-shaped accommodating part 210 is comprised, the extruded preliminary | backup screw 240 can be received stably. In addition, since the opening 212 is formed, the spare screw 240 once received by the accommodating portion 210 can be easily taken out.

  Furthermore, since the inside of the accommodating part 210 can be visually recognized through the wall part in which the opening part 212 was formed, it is easy to confirm the reserve screw 240 pushed out from the temporary holding part 130 and accommodated in the accommodating part 210. It has become. Therefore, the take-out operation can be easily performed, and the workability can be improved.

  Moreover, since the opening part 212 is distribute | arranged by the one side wall part, it can take out from the accommodating part 210 easily by approaching the reserve screw 240 to the one side wall part.

  In addition, since the bottom wall portion 216 constitutes a part of the opening 212, the bottom wall portion 216 continues to reach the opening edge of the opening 212. Therefore, it becomes easy to take out the spare screw received in the accommodating portion 210. In other words, the opening 212 is formed in such a manner that the wall surface of the bottom wall 216 continues in the opening region of the opening 212, so that the bottom of the opening 212 does not have a stepped shape. ing. Therefore, it becomes easier to take out the spare screw received in the accommodating portion.

  In the present embodiment, the spacer member 200 is engaged on the surface of the holding member 110 on the case member 120 side, and the engagement cannot be released by a manual operation from the outside of the substrate case unit 100. In other words, the spacer member 200 cannot be removed unless the case member 120 or the holding member 110 is removed. Since the traces remain when the case member 120 and the holding member 110 are removed, the traces are surely left when the spacer member 200 is taken away.
