Abstract:
A biaxial driving mechanism, which consists of a horizontal rotating mechanism for rotating a driven part around a rotating axis A and a vertical rotating mechanism for rotating said driven part around a rotating axis B being vertical for said rotating axis A, wherein:said horizontal rotating mechanism, comprising: a ring gear, which is a ring shaped gear and is positioned in a state that its center axis is the same as that of said rotating axis A, holds said driven part; and a motor for rotationally driving said ring gear around said rotating axis A, said vertical rotating mechanism, comprising: an end cam gear, which is a ring shaped gear and is positioned in a state that its center axis is the same as that of said rotating axis A, whose height position of the upper face changes along its circumference direction; a motor for rotationally driving said end cam gear around said rotating axis A; a link mechanism, whose one end is fitted to said driven part in a state that said one end can rotate and the other end contacts said upper face of said end cam gear, transfers a rotation of said end cam gear to said driven part as a vertical rotation around said rotating axis B via its own parallel movement; and a pushing mechanism for pushing said link mechanism to said end cam gear so that said other end of said link mechanism contacts the upper face of said end cam gear.
