PURPOSE:To provide a small and simple rotation device of a sample vessel wherein a rotation force from a driving source is accurately transmitted to the sample vessel even when the driving source having small torque is used. CONSTITUTION:A rotation device P1 of a sample vessel comprises an intermittent movement type belt conveyer 20, a needle member 3, a first driving means 4 that reciprocally move the needle member 3 along an axis line of the sample vessel 1 and a second driving means 5 that rotates the needle member 3 around the axis line. The needle member 3 consists of two parallel needle 8, 8 made of stainless steel and a disk-shaped mounting base 9 on which the needles 8, 8 are perpendicularly and eccentrically mounted. |
