PROBLEM TO BE SOLVED: To provide a board case unit capable of reliably preventing a fraudulent act to a control board.SOLUTION: A board case unit comprises: a seal sticking part X provided in a bottom case 120; a cutter reception part 128 provided in the seal sticking part X in a concave shape; a seal 150 stuck to the seal sticking part X; a guide projection 136 provided in a top case 130; and a seal cutter member 160 which comprises a breaking projection 161 m and a first elastic piece 164, and is attached to the inside of the cutter reception part 128 so as to be movable in a direction orthogonal to an opening/closing movement direction. When the top case 130 is moved relatively in an opening direction, the guide projection 136 comes into contact with the first elastic piece 164 and presses and moves the seal cutter member 160 in a direction orthogonal to the opening/closing movement direction. Thereby, the breaking projection 161 m projects from the cutter reception part 128, comes into contact with the seal 150, and breaks the seal.SELECTED DRAWING: Figure 7 |
