摘要： A light intensity control device includes a fixed opening 261, an aperture stop part 26 for controlling a light flux of incident light, a light intensity aperture part 24 for changing the size of an opening by moving a plurality of aperture blades to limit a light intensity of transmitted light and a ND filter 25 having a transparent area 253 and a light blocking area 254, which is arranged to be movable between a first light blocking state where the transparent area 253 faces the fixed opening 261 of the aperture stop part 26 and a second light blocking state where the light blocking area 254 faces the fixed opening. The moving of the ND filter 25 is carried out when the opening area of the light intensity aperture part 24 is a maximum.

摘要： A lens driving device includes a focus lens frame, first and second shafts, a rack member, a lead screw and a spring member. One or more lenses are attached to the focus lens frame. The first and second guide shafts are arranged parallel to an optical axis of one or more lenses, inserted into first and second holes of the focus lens frame and guide the focus lens frame. The rack member is supported by the focus lens frame in the vicinity of the first hole. The lead screw meshes with rack teeth formed on the rack member to move the focus lens frame along the optical axis. The spring member presses the rack teeth toward the lead screw to generate reaction force acting from the lead screw toward the rack teeth. A direction in which the reaction force acts crosses a face connecting the first and second guide shafts.
