摘要： An actuator which drives a lens frame in an optical axis direction is constructed by piezoelectric elements, driving members, and a pressing spring. The piezoelectric elements are placed at opposite sides with a driven plate therebetween, and the driving members are fixed to the respective piezoelectric elements. The driving members are pressed against the driven plate from both sides by the pressing spring.

摘要： A lens supporting frame is provided and includes a lens holder supporting a lens and a moving frame which is fitted to a cylindrical part of the lens holder to support the same. Ribs are provided at equal intervals in a rotation direction on a rear end face of the lens holder, the ribs having a plurality of inclined surfaces inclined respectively toward the front or rear ends of an optical axis. Abutting parts are provided on a rear end face of the moving frame so as to abut on the ribs. When the lens holder is rotated after mounting it in the moving frame, parts of the lens holder facing the abutting parts are moved in directions along the optical axis as a result of abutment between the inclined surfaces of the ribs and the abutting parts to change the inclination of the lens holder relative to the optical axis.

摘要： The rear projection lens device comprises a fixed lens barrel, a first lens barrel having a front lens group, a second lens barrel having a rear lens group, and a rotation stopper. The first lens barrel is helicoid-coupled with the fixed lens barrel, and moves in an optical axial direction by rotating relative to the fixed lens barrel. The second lens barrel is helicoid-coupled with the first lens barrel and moves in the optical axial direction so as to change an interval between the front lens group and the rear lens group when the first lens barrel rotates. The rotation stopper allows the second lens barrel to move in the optical axial direction, but stops the rotation around the optical axis. A zoom adjustment and aberration correction associated with the zoom adjustment are conducted concurrently only by rotating the first lens barrel.

摘要： An image displayed on a liquid crystal panel is projected on a projection surface by a projection lens. An optical axis of a projection lens is perpendicular to the projection surface. However, alight emitting optical axis of a distance measurement light and an optical axis of a light receiving lens is inclined with respect to the optical axis of a projection lens, not to be perpendicular to the projection surface. A distance measurement unit is formed by unitizing a light emitting element, a light emitting lens, the light receiving lens, and a light receiving element, and the distance measurement unit is held with the projection lens by a common holder. Even if a surface like a whiteboard which has high reflectivity is used as the projection surface, high accuracy of the distance measurement is kept because diffused light from the light emitting lens, which is regularly reflected from the projection surface, is away from an effective photodetecting region of the light receiving element.

摘要： An image displayed on a liquid crystal panel is projected on a projection surface by a projection lens such that the optical axis of the projection lens is perpendicular to the projection surface. An optical axis of a distance measurement light and an optical axis of a light receiving lens are each inclined a specified angle with respect to the optical axis of the projection lens to be not perpendicular to the projection surface so as to reduce noise caused by specularly reflected light that otherwise would be detected by the distance measurement unit when a highly reflective whiteboard is utilized as the projection surface. The distance measurement unit is formed by unitizing a light emitting element, a light emitting lens, the light receiving lens, and a light receiving element, and the distance measurement unit is held with the projection lens by a common holder.
