PROBLEM TO BE SOLVED: To stably hold a panel board at an erect position, by simplifying a constitution of a means for holding the board at the erect position. SOLUTION: A panel board device comprises a base substrate 11, the panel board 21 pivoted to the substrate and rotatable between a laid-down position A covering an outer surface of the substrate from an outside and an erect it position B separated from the outer surface of the substrate by laying down, and a protrusion 15 for deflecting the panel board provided at the substrate and disposed at the erected position to hold the board at the erect position. In this case, the protrusion 15 presses the center of the side edge to turn into a lower part of the board at the position B from the position of the laid-down position A side to the panel board 21, disposed at the erect position A toward the opposite side to the position A, to deflect the entire board 21 disposed at the position B to hold the board at the erect position. |
