WIPO Patent Application WO/2022/097398
Kind Code:
A1
Abstract:
An optical line sensor 1 is provided with an illumination unit 2, a light receiving unit 3, and a pair of holding members 4 which are detachably attached to both ends, in a main scanning direction, of the light receiving unit 3. The illumination unit 2 is provided with engaging portions (protruding portions 25) at both ends, in the main scanning direction, of the illumination unit 2. Each holding member 4 is provided with an engaged portion (hole portion 41). In a state in which the engaging portions and the engaged portions are engaged with one another, the illumination unit 2 is positioned, and is held integrally with the light receiving unit 3, in such a way that the emission optical axis of light emitted from the illumination unit 2 overlaps the received light optical axis in a position substantially coinciding with a reading line of the light receiving unit 3.
