SOLUTION: An exclusive case 14, wherein an insertion and a drawing-out of burn-in boards B are performed in an aperture 14a provided in the case 14, is made to support by a base 13 having a vertically moving mechanism 15 and a rotating mechanism 17. In the case 14, an engaging mechanism 41 capable of engaging the end parts of the burn-in boards B is movably provided in the depthwise direction of the case 14. An aperture 2 provided in a 6-step rack 1A of a truck 21A coupled with the base 13 is made to abut on the aperture 14a provided in the case 14, and the mechanism 41 is made to engage with the burn-in boards B to move the boards B in the depthwise direction of the case 14 and makes the boards B house in a housing space 34. By rotating the case 14, an aperture 2 provided in a 12-step rack 1B of a truck 21B is made to abut on the aperture 14a provided in the case 14, the mechanism 41 is moved to the side of the aperture 14a to release the engaging of the boards B.</p> |
