摘要

A biaxial driving mechanism, an image inputting apparatus used this biaxial driving mechanism and a light projecting apparatus used this biaxial driving mechanism, in which a mirror positioned in front of a camera or a light projecting instrument is rotated biaxially, and takes an image of a desiring direction or projects an image to a desiring direction without having an electric connection between the mirror and a driving part, are provided. In the biaxial driving mechanism, a horizontal rotating mechanism provides a ring gear, whose center axis is the same as that of an optical axis of a camera, holds a mirror, and a motor for rotating the ring gear around the optical axis of the camera. And also, in the biaxial driving mechanism, a vertical rotating mechanism provides an end cam gear, whose center axis is the same as that of the optical axis of the camera and its thickness changes along its circumference direction, a motor for rotating the end cam gear around the optical axis of the camera, a link mechanism, whose one end is fitted to the mirror in a stage that the one end can rotate, and at the other end a rolling bearing is fitted and the rolling bearing contacts the upper face of the end cam gear, and a spring pushes the link mechanism to the end cam gear.
