PROBLEM TO BE SOLVED: To realize a structure in which a plurality of boards can be housed in an enclosure, and each board can be easily pulled out/inserted without increasing the size of the enclosure.SOLUTION: A board housing structure comprises: an enclosure 2 having a first surface VS1 and a second surface VS2; a first board 11 housed into the enclosure 2; a second board 12 housed into the enclosure 2; a plate-shaped first structure 13 approximately vertically connected to an end of the first board 11; and a plate-shaped second structure 14 approximately vertically connected to an end of the second board 12. The first surface VS1 has a first opening OP1 through which the first board 11 is pulled out/inserted along a first direction, and the second surface VS2 has a second opening OP2 through which the second board is pulled out/inserted along a second direction different from the first direction. In the state where the first board 11 and the second board 12 are housed in the enclosure 2, the first surface VS1 and the first structure 13, and the second surface VS2 and the second structure 14 are approximately parallel with each other, and the first board 11 and the second board 12 are approximately parallel with each other.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2017,JPO&INPIT【課題】筐体内に複数の基板を収納でき、かつ、筐体を大型化することなく夫々の基板を容易に抜き差しできる構造を実現する。【解決手段】基板収納構造は、第1面VS1および第2面VS2を有する筐体2と、筐体2に収納される第1基板11と、筐体2に収納される第2基板12と、第1基板11の端に略垂直に接続される板状の第1構造体13と、第2基板12の端に略垂直に接続される板状の第2構造体14と、を備える。第1面VS1は、第1方向に沿って第1基板11を抜き差しする第1開口部OP1を有し、第2面VS2は、第1方向と異なる第2方向に沿って第2基板を抜き差しする第2開口部OP2を有する。第1基板11および第2基板12を筐体2に収納した状態で、第1面VS1と第1構造体13、および、第2面VS2と第2構造体14とがそれぞれ略平行であり、かつ、第1基板11と第2基板12とが互いに略平行である。【選択図】図1
