PROBLEM TO BE SOLVED: To provide a board case of a game machine capable of effectively preventing execution of a fraud onto a control board on which electronic components such as a ROM are mounted, by preventing a seal from being peeled off without leaving a trace and making it hard to open the board case.SOLUTION: The board case comprises a base body 3, a lid body 5, and a protective cover 7. The protective cover 7 protects a seal 45 and sealing parts (a one-way screw 27, a caulking pin 28, a ring 17, and cylindrical members 14 and 34) by covering them. Further, the protective cover is fitted to the base body 3 and the lid body 5 in such a manner as to seal the board case by the one-way screw 73, a screw 74, and a locking piece 79, so as to regulate slide movement between the base body 3 and the lid body 5. |
