PROBLEM TO BE SOLVED: To provide a board-supporting apparatus which is easy to support and insert/remove the board, having a small number of components and a simple structure, while the area of a component mounting space or a pattern of the board is enlarged. SOLUTION: The board-supporting apparatus includes supporting rods 11a and 11b, provided between upper edges or lower edges on the rear side of a both side frame 6. The supporting rods 11a and 11b are made up of a slant base 12, a horizontal part 13 formed on one side of the base 12 and located above or below each board 8, and a vertical part 14 formed on the other side of the base and located at the rear side of each board 8. The board-supporting apparatus includes a supporting part 15, located at both edges and supported pivotally at the both side frame 6, a fixing part 17 located at both edges of the supporting rods 11a and 11b and fixed freely removably at the both side frames 6, a plurality of slits 19 formed at the base 12 for inserting an angular part of each board 8 on the rear side thereof when the board 8 is mounted, and plurality of guide grooves 20 formed at the horizontal part 13 for guiding each board 8 during rotation of the supporitng rods 11a and 11b, when the board 8 is mounted or removed.
