<P>PROBLEM TO BE SOLVED: To provide a board case of a game machine which can surely find the opening of the case. <P>SOLUTION: The board case 100 has a seal mounting part 105 for sticking a seal 104 with a built-in IC tag 116 at a part in which an upper case 101 and a lower case 102 are piled up. The seal mounting part is configured to generate a difference in sticking strength with the connection area vicinity of a chip 116a and antenna 116b of the IC tag as a boundary when a seal is stuck. A seal cover 110 put on the seal mounting part has an adhesion part facing a part in which the sticking strength of the seal is lowered. When the seal cover is pulled out toward one side in order to open the board case, since at least the connection area vicinity of the seal is easy to be torn, the part attached to the seal cover is torn off, and the IC tag is cut off in the vicinity of the connection area of the chip and the antenna. <P>COPYRIGHT: (C)2012,JPO&INPIT |
