Abstract
An optical axis adjuster is provided to change the optical axis direction of a transmitter unit having a transmitter element . A restriction member is latched in an external thread which is formed in the outer circumferential surface of the adjuster . The adjuster is held by a rotation/revolution support member and rotatable around its central axis O. The rotation/revolution support member is rotatable around a rotation axis extending perpendicularly to the central axis O. Stepped adjustment of the optical axis is effected by revolving the adjuster around the revolution axis such that the restriction member climbs over a thread ridge. Stepless adjustment of the optical axis is conducted by moving the adjuster in cooperation with its rotation around the central axis O, with the restriction member keeping a latched engagement with a thread groove.
