<p>Provided is a sensor holder (10) that is capable of meeting a demand for a tilt adjustment of a sensor substrate (70) and a demand which does not require the tilt adjustment. Bosses (20, 30, 40) are formed on the sensor holder (10). Position control sections (22, 32, 42) are formed on the outer sides of these bosses (20, etc.). The sensor substrate (70), on which through-holes (71, 72, 73) larger than the size of the bosses (20, etc.) are created, is attached to the sensor holder (10). The bosses (20, 30, 40) run through the through-holes (71, 72, 73) in the sensor substrate (70) until prohibited by the position control sections (22, 32, 42), and secured with screws (91, 92, 93). The sensor substrate (70) can be tilted rearward by loosening the screws (91, 92, 93), whereby the tilt adjustment is enabled. When the through-holes (71, etc.) are small, the apical surfaces of the bosses (20) hit against the front surface of the sensor substrate (70), whereby the tilt adjustment is disabled.</p> |
