Abstract
A sampling needle () is inserted into a sample container () by a needle-driving mechanism () to collect a sample liquid from the sample container. A depth information acquirer () acquires insertion depth information, i.e., a piece of information concerning an insertion depth of the sampling needle into the sample container. A needle-rinsing length setter () sets a needle-rinsing length which is an insertion length of the sampling needle into a rinse storage tank () having an open top, based on the insertion depth information. A controller () controls the needle-driving mechanism so that a portion of the sampling needle extending from the tip of the sampling needle over the needle-rinsing length is inserted into the rinse storage tank. The needle-rinsing length setter is configured to set a shorter needle-rinsing length for a smaller insertion depth of the sampling needle into the sample container, to shorten the needle-cleaning time.
