Abstract:
1. A lens apparatus, comprising: a lens barrel; a first guide shaft which is provided parallel to an optical axis in the lens barrel; a second guide shaft which is provided parallel to the optical axis in the lens barrel; a first guide shaft front end fixing part which is provided to the lens barrel and to which a front end of the first guide shaft is fixed; a first guide shaft rear end fixing part which is provided to the lens barrel and to which a rear end of the first guide shaft is fixed; a second guide shaft front end supporting part which is provided to the lens barrel and swingably supports a front end of the second guide shaft; a second guide shaft rear end supporting part which is provided to the lens barrel as one of a horizontal elongate hole and a vertical elongate hole and into which a rear end of the second guide shaft is fitted to be supported movably only in one of a horizontal direction and a vertical direction; a lens frame which holds a lens; a first guide part which is provided to the lens frame and is engaged with the first guide shaft to thereby guide a move of the lens frame; a second guide part which is provided to the lens frame and is engaged with the second guide shaft to thereby guide the move of the lens frame; a swinging member which is provided to the lens barrel swingably with respect to a swinging shaft which is parallel to the optical axis; a first elongate hole which is formed in the swinging member and through which the second guide shaft is inserted; a rotating member which is provided to the lens barrel rotatably with respect to a rotating shaft which is parallel to the optical axis; an eccentric pin which is provided to the rotating member parallel to the optical axis and is provided eccentrically with respect to the rotating shaft; a second elongate hole which is formed in the swinging member and through which the eccentric pin is inserted; and a linear actuator which moves the lens frame, wherein the second guide shaft is swung one of horizontally and vertically by rotating the rotating member, to thereby enable adjusting one of horizontal inclination and vertical inclination of the optical axis of the lens.
