<p>A technology provided by the present invention, as an aspect, is provided to reduce the reduction of the mounting space of an electronic component on a first substrate. A rack mounting device (20) includes a mounting case (22), a main part (40), and a sub part (60). A guide rail (80) which is supported to be able to rotate in the mounting case (22) is arranged in the other side of the mounting case (22). An entrance part (96) which a main side connector (46) enters is formed in the guide rail (80). By the guide rail (80), the sub part (60) is supported to slide and a sub side connector (72) is guided to the main side connector (46). A pair of tilted parts (98) is formed in the edge of both sides of the entrance part (96) in a rotation direction of the guide rail (80). A pair of stopper parts (99A, 99B) which limits the rotation range of the guide rail (80) is arranged in both sides of the rotation direction of the guide rail (80).</p> |
