Abstract: A television lens apparatus in which circuit boards can be easily mounted or dismounted and can be easily wired is provided. A lens barrel is contained in a housing. A housing opening is formed in the lens barrel to be opened and closed with a rotatable lid. A board holding device is fixed on a rear portion of the lens barrel. In the board holding device, four connectors are mounted on a wiring board and arranged in an axial direction of the lens barrel. Four circuit boards are inserted in the connectors through the housing opening in a direction perpendicular to the lens barrel.

Abstract: The invention provides a floating lens device capable of moving a plurality of lens groups by a different amount, wherein the lens device can be miniaturized in a direction of the optical axis. A lens device according to the invention includes: a fixed lens barrel; lens frames respectively holding a plurality of focus lens groups having a movement pattern different from each other; cam pins arranged respectively in the lens frames; a cam cylinder rotatably supported and at the same time having cam grooves engaged respectively with the cam pins. The lens frame is disposed in the inner side of the lens frame and combined with the lens frame in a nested manner, and the cam pins are disposed at a position different from each other in a circumferential direction and at the same time at substantially the same position in a direction of the optical axis.
