PROBLEM TO BE SOLVED: To eliminate the possibility of replacing electronic components mounted on a circuit board without unsealing a board case in the board case for housing the circuit board in a game machine. SOLUTION: The board case 1 is provided with a case fixing mechanism 40 for fixing a base member 10 and a cover member 20 in contact with it and a board fixing screw 60 which fixes the circuit board 30 on the base member 10 keeping the mounted surface of the circuit board 30 unparallel with non-parallel contact parts 15a and 25a of the base member 10 and the cover member 20. Therefore, even if the third party attempts to replace the electronic components 34 by inserting a tool such as a barlike member through a clearance of the non-parallel contact parts 15a and 25a, this makes it harder to catch them. Thus, the replacement of the electronic components 34 mounted on the circuit board 30 can be made highly difficult without unsealing the board case 1. COPYRIGHT: (C)2008,JPO&INPIT
