PROBLEM TO BE SOLVED: To provide a board case unit which enables prevention and early detection of a fraudulent act to a control board.SOLUTION: A board case unit comprises a seal 170 stuck to a bottom side engaging part 150 and a seal cutter 180 attached to the bottom side engaging part 150 in a fixed state. By engaging an engaging arm 181 of the seal cutter 180 and an engaging arm 161 of a top side engaging part 160, the slide movement of a top case in an opening direction is restricted. By cutting the top case and a portion of the seal cutter 180 and dividing the seal cutter 180 into a fixed portion fixed to the bottom side engaging part 150 and a fracture portion having the engaging arm 181, the top case can slide in the opening direction. When the top case slides in the opening direction, the fracture portion of the seal cutter 180 also slides together and breaks the seal 170. |
