Abstract
A lens holder, which supports a light receiving lens, is screwed into a barrel portion of a body holder by respectively engaging hooks, which are provided in a screwing piece, with engaging-grooves formed in an end surface of the lens holder and then rotating the screwing piece. The screwing position of the lens holder is controlled so that the rotational direction position of a set of the engaging grooves is coincided with a reference position of an adjusting piece. Subsequently, the adjusting piece is engaged with the lens holder at the reference position. Then, a focus adjustment is performed by rotating the lens holder in a positive rotation direction.
Claims3
A method of manufacturing a camera module comprising a body holder including a barrel portion, and a lens holder supporting a light receiving lens and including an engaging-groove formed in its end surface, the method comprising steps of:
- screwing the lens holder into the barrel portion of the body holder by engaging a hook provided in a screwing piece with the engaging-groove of the lens holder;
- and
- performing a focus adjustment by engaging a hook of an adjusting piece with the engaging-groove of the lens holder at a reference position, and rotating the lens holder in a positive rotation direction by using the adjusting piece to adjust a position of the light receiving lens to a focus position,
- wherein when the lens holder is screwed into the barrel portion by using the screwing piece, a screwing position of the lens holder is controlled so that a position of the engaging groove of the lens holder coincides with the reference position of the adjusting piece.
