Abstract

PURPOSE:To improve the precision of stop location of the pipet by providing a elastic body to the turning pulley mounting end of the belt which is tightened between the fixed pulley and turning pulley. CONSTITUTION:The turning pulley 4 is rotatably mounted on the end of arm 2, the fixed pulley 5, the diameter of which is the same as that of the pulley 4, is attached to the main shaft 1 so that it does not turn with the rotation of main shaft. The coilwise spring 9 connected to the tip of string 6 is fixed to the turning pulley 4 to tense the string 6. When the arm 2 is turned in the S-direction, a part of string winded around the fixed pulley 5 is decreased, the decreased portion is winded around the turning pulley 4. Since the turning pulley 4 is exactly turned by a pulling force of the spring 9, the pipet 3 is always located at the lowest end of the turning pulley, that is, P1, P2 and P3, and is vertical downwards.
