PROBLEM TO BE SOLVED: To easily detect fraudulent replacement of a board case, and to easily detect fraudulent replacement of a board due to breakage of a sealing means. SOLUTION: The board case for storing a main control board includes a body case 15, a cover case 16 for removably covering the body case 15, and sealing means 45a to 45d for sealing the cover case 16 to the body case 15 not to be opened. Information communicating devices 75a to 75d for communicating information with the outside on discriminating whether or not the correspondence relationship between the main control board and the pachinko machine is correct are provided on the cut parts 55a to 55d of the sealing means 45a to 45d. In opening, simultaneously with cutting the cut part 55a of the sealing means 45a provided for sealing, the information communicating device 75a is broken so that the information from the information communicating device 75a is not communicated, whereby it is easily discovered whether the board case 8 is replaced or not, and whether the main control board is fraudulently replaced or not.
