Abstract:
A specimen-conveying conveyor comprises:a holding roller mechanism including a plurality of roller units having a plurality of holding rollers, which are arranged in a horizontal direction so as to form a valley region in which a test tube is laid down and held, along a conveyance path wherein the roller units are coupled to each other along the conveyance paths and an outside diameter of each of the holding rollers is set so as to alternately increase and decrease gradually along an axis of each of the rollers; a rotation driving mechanism which simultaneously rotates the holding rollers of the roller unit of the holding roller mechanism in a first direction and thus rotates the test tube laid down and held in the valley region in a second direction opposite to the first direction; and a slide driving mechanism which slides the test tube laid down and held in the valley region in a direction along an axis of each of the holding rollers.
