发明名称 Lens moving mechanism and liquid crystal projector
摘要 The object of the present invention is to further improve a lens barrel moving mechanism of a liquid crystal projector and to provide a lens moving mechanism which has simple structure and is capable of achieving the smooth and high precision movement of a lens barrel, and a liquid crystal projector employing the lens moving mechanism. The present invention provides a lens moving mechanism for moving a lens retaining member 20, which retains a lens barrel 15 provided therein with a projection lens for projecting light with image information, in the directions of Z axis and X axis. The lens moving mechanism comprises first and second guiding mechanisms 23, 23, 24, 24 including a track member, a movable member, and a plurality of rolling members arranged between a rolling member running surface of the track member and a rolling member running surface of the movable member, whereby the lens barrel 15 is guided by the first and the second guiding mechanisms 23, 23, 24, 24 in the directions of Z axis and X axis.
