Abstract

A piercer washing port is provided at a position on the trajectory of a piercer differing from the sampling position. The piercer washing port is cylindrically shaped and has an opening for inserting the piercer in the upper surface and a washing space for housing the piercer inserted from the opening. Air injection ports for injecting air and washing liquid expelling ports for expelling water serving as a washing liquid are provided on the inside wall surface of the piercer washing port. The air injection ports are provided at four locations equally spaced on the periphery along the inside wall surface of the washing space. The washing liquid expelling ports 44 are provided at four locations equally spaced on the periphery along the inside wall surface of the washing space at different positions than those of the air injection ports.
