Abstract

The lens switch apparatus of present invention comprises lens mounts, lenses, a carrier, rotating axes, at least one belt, gears, motion mechanisms and the power sources. The lens mounts include the first lens mount and the second lens mount. Several lenses are positioned on the lens mounts. The carrier, on which the above lens and the lens mounts are positioned, serves as the plate to move the lens. The motion mechanism, which further includes the first motion mechanism and the second motion mechanism. The first motion mechanism move the carrier toward the first direction to focus lens properly. Besides, the second motion mechanism move the first motion mechanism toward the second direction to align lens to the optical axis. The rotating axis, which comprises the first rotating axis and the second rotating axis. Through the first rotating axis, the first lens mount is coupled to the carrier. Similarly, through the second rotating axis, the second lens mount is coupled to the carrier. The third power source, through the belt and the first gear, is coupled to the first rotating axis. Similarly, through the belt and the second gear, the third power is coupled to the second rotating axis. In this manner, the first lens mount and the second lens mount are rotated by the third power source.
