  • the module With formation of the module as described above, if modules corresponding to the kinds of the blood collection tube are prepared, even when the tube kind of the blood collection tube is to be changed, it is only necessary to replace the module, and thus extremely easy and prompt handling operation is possible.
  • the blood collection tube storage box can be send back for repair on a module basis, and the repair can be easily performed even at remote locations.
  • the lower end surfaces of the cap of the blood collection tube are respectively supported by the two blood collection tube support rails. Therefore, it is possible to store a large number of blood collection tubes between the two support rails only by inserting the blood collection tubes therebetween. Further, the blood collection tube is transferred through bringing the transferring belt into contact with a side surface of the blood collection tube main body. With the above-mentioned storing method and conveying method for the blood collection tube, the transferring belt and the cap of the blood collection tube are not brought into contact with each other, and hence there is no fear that the blood collection tube slips down due to distortion of the transferring belt.
  • Isolation of the blood collection tube is performed through alternately causing the first stopper and the second stopper to operate, the first stopper being capable of moving close to and away from the front surface of the cap of the leading blood collection tube, the second stopper having a fork-like shape and being capable of moving close to and away from the gap from above, the gap being formed between the caps of the leading and second blood collection tubes.
