| Zusammenfassung: | An optical line sensor 1 includes an illumination unit 2, a light receiving unit 3, and a pair of holding members 4 separably attached to the light receiving unit 3 at both ends in a main scanning direction. The illumination unit 2 includes fitting portions (protrusions 25) at both ends in the main scanning direction. Each of the holding members 4 includes a fitted portion (hole 41). In a state where the fitting portion and the fitted portion are fitted, the illumination unit 2 is positioned so that the irradiation optical axis of light emitted from the illumination unit 2 overlaps the light receiving optical axis at a position substantially coinciding with a reading line of the light receiving unit 3 and is integrally held with the light receiving unit 3. |
