Automatic needle remover from the used syringe for the in jection was developed which is movable and capable of high speed operation. A series of operations for the removal of the needle was realized by menas of two air cylinders driven by the compressed air of the pressure of 400 kPa fed from a 3.5 - liter air container. One of these air cylinders is powerful one and its dimensions are 16 mm in inner diameter and 30 mm in stroke. This produces the driving force sufficient to remove the needle from the used syringe. The other is precision one for the position control of the removing plate of phosphor bronze. Net time length necessary for the removal of a needle was less than 260 ms. In the test operation, two hundreds of used syringes were treated successively without any trouble. Pressure loss for the test operation was 800 kPa at the starting pressure of 114 MPa.
