| 摘要 |
An aspect of the invention provides an imaging device for measurement processing, which comprises: an imaging unit that forms an image; a lens positioned to guide incident light to the imaging unit; and an adjustment mechanism that adjusts the distance between the lens and the imaging unit by moving the lens along the optical axis of the lens, the optical axis extending in a first direction, the adjustment mechanism comprising: a first threaded member having a longitudinal axis extending in a second direction that is different from the first direction, wherein the first threaded member is rotatable around longitudinal axis thereof without moving in the second direction; and a conversion mechanism that converts a rotation of the first threaded member around longitudinal axis thereof into a movement of the lens along the optical axis of the lens.
