Abstract: In a case where a dispensing tip is imaged from below, liquid attached to the tip falls downward and contaminates an imaging mechanism. An automatic analyzer includes: a buffer that has a hole for holding a tip for dispensing, the hole passing through the tip; a probe for dispensing having a tip to which the tip is attached; an imaging unit that images the tip; and a controller that controls the tip such that the tip is mounted on the probe by pressing the probe against the tip that passes through the hole to be held by the buffer, in which the imaging unit is disposed to image the tip from an upper side to a lower side in a gravity direction.
