<p>PROBLEM TO BE SOLVED: To accurately position a gap of photointerrupter and a light-shielding plate to be detected in a lens driver. SOLUTION: When a photointerrupter 60 is fixed to the base 10 of the lens driver, a coupling part 13c as a positioning part is formed in one body on a projection base 13, the coupling part 13c is fitted into the gap (slit) 63 of the photointerrupter 60 and the gap 63 is directly positioned. By this manner, a plate to be detected 36 of a lens holding member 30 guided in the light axis direction L against the base 10 moves inside the gap 63 without touching and shield light. Thus, a home position of the lens holding member 30 can be detected.</p> |
