Abstract
An optical axis adjustment jig includes a main unit portion that is configured to be disposed between a pair of head units, and is fashioned in a flat plate shape. The main unit portion includes a reference portion for adjusting a distance between the head units, and an inclination of an optical axis of each of the head units, and a screen portion for aligning the optical axes of the head units. The reference portion and the screen portion are disposed arrayed in a direction orthogonal to a thickness direction of the main unit portion.
Claims3
An optical axis adjustment jig used to adjust an optical axis of each of a pair of measurement head units disposed at positions sandwiching a sheet body conveyed by a conveying roller, in a thickness direction of the sheet body, the measurement head units being configured to measure a thickness of the sheet body, the optical axis adjustment jig comprising:
- a main unit portion that is configured to be disposed between the measurement head units, and has a flat plate shape, the main unit portion comprising:
- a mirror for adjusting a distance between the measurement head units, and an inclination of the optical axis of each of the measurement head units;
- and
- an opening for aligning the optical axes of the measurement head units,
- wherein the mirror and the opening are disposed in a direction in which the optical axis adjustment jig is configured to slide that is orthogonal to a thickness direction of the main unit portion and spaced apart from each other.
