CONTROL BOARD BOX, MOLDING DIE, AND INJECTION MOLDING METHOD

PROBLEM TO BE SOLVED: To expose a connector alone outside without exposing a wire pattern of a control board of a game machine. SOLUTION: A control board 10 is placed into a lower box part 18 to be fixed by a screw 70, a connector 12 is put through connector holes 20a-20h and a connector guide 20 is placed on the control board 10 to put an upper box part 16 to the lower box part 18. Then, a screw passage 30 is aligned with a screw receptacle 42 and a screw passage 32 with a screw receptacle 44. Four sets of the screw passages 30 and the screw receptacles 42 are screwed down by a screw 71 while being tapped, and one set of the screw passage 32 and the screw receptacle 44 per side face 38 (total of two sets) is threadedly engaged by a special screw 73 while being tapped. When the control board box 14 is closed, since the connector 12 alone is exposed outside and the wire pattern is not exposed at all, the fraudulent modification of altering a part of the wiring pattern or exchanging or adding some parts is surely prevented.
