Imaging device

Abstract

Provided is a technique for detecting deviation amounts in two directions between a tip of a nozzle of a pipetting device and a target stop position from one image. An imaging device of the present disclosure is an imaging device installed in a pipetting device including a nozzle that aspirates and dispenses liquid and an arm that holds the nozzle and moves the nozzle by a rotation operation. The imaging device includes: a camera that includes an image sensor and a lens; and a pair of mirrors that includes a first mirror having a first reflective surface and a second mirror having a second reflective surface. The pair of mirrors is arranged such that the first reflective surface and the second reflective surface face each other. The pair of mirrors is arranged one by one between the tip of the nozzle and a bottom surface of the arm, on both sides across a plane that includes a rotation axis of the arm and a central axis of the nozzle. The first mirror is disposed closer to the arm than the second mirror, with the first reflective surface facing toward the tip of the nozzle, and the second reflective surface facing toward the camera.

Dependencies are inferred from the claim text.
