Abstract: An adapter is attached to each sample storage unit in a rack. Each adapter includes a pair of arms, and these arms include a pair of lower-end structural bodies. An opening force being imparted to a pair of the lower-end structural bodies in the horizontal direction when a sample container is mounted on the pair of lower-end structural bodies causes the bodies to retreat towards the outside in the horizontal direction. In the subsequent opened state, the sample container is passed from the rack to a lifting mechanism. In the closed state, pressure being applied to the sample container in the vertical direction causes a stopper segment, which is contained in each attachment, to be lowered. In this lowered state, the opening motion of the pair of arms is restricted.

Abstract: Each adapter disposed on a rack includes a pair of arms that configure an opening/closing mechanism. During rack conveyance, a guiding block is slotted between a pair of legs contained in the rack. The opening/closing mechanism being abutted against the guiding block causes the opening/closing mechanism to perform an opening/closing operation. When the state of the opening/closing mechanism is changed from closed to open, a pre-measurement sample container is passed from a sample storage unit to a lifting mechanism. Subsequent to the post-measurement sample container being returned to the sample storage unit, the state of the opening/closing mechanism is changed from open to closed.
