  • Patent number: 10099866
    Abstract: A transport apparatus transports sample holder racks. The apparatus employs a first transport unit that moves the rack in a path between two ends of the transport apparatus, a rack sender unit that extends in a first direction that intersects the path, a second transport unit dimensioned parallel to the first transport unit and with the rack sender unit interposed therebetween, which locates the sample container held in the rack at a sample loading position of a measurement device, and a first movable member capable of moving in the first direction between the first and the second transport units. The apparatus has movable portions that alternately stop the rack movement, and push the rack such that optimal movement is achieved whereby the rack moves beyond the rack sender unit to the second transport unit as the first movable member moves in the first direction.
