Abstract
A focus and optical axis adjustment mechanism for a semiconductor laser and a collimator lens is disclosed. A first holding member for holding a semiconductor laser is attached to an intermediate member so that it is movable on a plane vertical to the optical axis of the semiconductor laser. The intermediate member is attached to a second holding member which holds a collimator lens so that it can be bent with a portion near one end thereof as the bending line.
