PURPOSE:To perform smoothly a transfer of sample between the conveying belts by a method wherein the conveying belts are provided in such a way that both end parts of the conveying belts interlock the opening and closing of the valve to intercept the air-vacuum space or the space between vacuums and are inserted in the hole of the valve or are detached from the hole. CONSTITUTION:When samples 61 are placed in order on a belt 36 by the intermittent descent of a cassette 60, a cylinder 23 is actuated, a valve 21 is made to descend and a hole 24 is opened. At the same time, a lever 51 is made to rotate, a member 52 is made to shift to the side of a chamber 10 against a spring 54 and a belt 30 including a pulley 34d is made to stop in a state that the end part thereof is being inserted in the hole 24. A sample 61 is transferred in a state that both end parts of the belt 30 and a belt 40 are mutually approaching and after the transfer is completed, the hole 24 is shut by a valve 21. Herewith, the end part of the belt 30 is returned outside the hole 24 and the member 32 is made to stop by a stopper 35. |
