摘要

PURPOSE:To obtain efficiency and to perform maintenance operation such as the replacement of a needle block and the carrying-out operation of a disposal jag by providing an automatic manipulator with a function of moving even to a cylindrical coordinate system simultaneously upward/downward movement. CONSTITUTION:A needle block 2 consists of a liquid reservoir part 3 and a needle part 4 and is arranged at the circumference of the wall surface in an inner box 1. The automatic manipulator 8 is a cylindrical coordinate type and approaches an optional block 2 and a jag sending and receiving opening 7 through the upward/downward movement by a ball screw 9 and the rotation by a gear 10. An air sending device 6 sends the externally received jag to a manipulator hand part 5 from the sending and receiving opening 7 with air and a jag after sampling is sent into the device 6 from the sensing and receiving opening 7. The manipulator 8 stores a disposal jag receiving block 14 which contains the disposal jag in a conveyance container in an article carrying-in/out port 1, and also detaches and carries the closed needle part 4 out of the port 13 and fits a preliminary needle part in a specific block at the time of the replacement of the needle part 4.
