Abstract: PURPOSE: A focus controller of a beam projector is provided to minutely adjust focus of a beam projector by straight line moving a lens assembly in the direction of an optical axis. CONSTITUTION: A focus controller of a beam projector comprises an adjusting member(110), a rotational eccentric member, a focus guide member(120) and a moveable member(130). The adjusting member is installed at a beam projector to rotate in order to adjust focus. The rotational eccentric member is included on the adjusting member. The rotational eccentric member has a central axis eccentric in the pivot axis of the adjusting member. The moveable member is located at a lens assembly and combined with the focus guide member.
