摘要： A waterproof operation mechanism of an interchangeable lens barrel having an operation member which is rotatably set around a periphery of the interchangeable lens barrel. A button engages with the operation member such that the button penetrates the operation member and protrudes outward from the operation member. The button functions to fix the operation member at a predetermined rotation position and to release the operation member from the predetermined rotation position. The interchangeable lens barrel includes a knurled part around its periphery, the knurled part being made of an elastic material and having a protruding portion integrally formed therewith to cover the button. Further, the operation member includes a fitting groove on a periphery of the operation member to prevent the knurled part from being displaced in a direction of an optical axis of the lens barrel.

摘要： A lens barrel which can be easily switched between a manual focusing mode and an auto-focusing mode employs a motor as a drive power source for driving a switching apparatus for switching between an auto-focusing apparatus and a manual focusing apparatus. When a photographer supplies an external electrical signal, a switching operation from the auto-focusing apparatus to the manual focusing apparatus and vice versa can be performed in accordance with the forward/reverse rotational direction of the motor.

摘要： An auto-focusing device adapted for use with a camera. The device includes an auto-focusing optical system having a lens barrel anchoring section, a support member and a drive unit for causing the auto-focusing optical system to be moved into a desired position. The drive unit causes the auto-focusing optical system to be moved along a plane containing the optical axis of the auto-focusing optical system. The support member supports the auto-focusing device in the camera. The device also includes an energizing member which eliminates extraneous movement of the auto-focusing optical system. The energizing member has particular energizing characteristics and is positioned between the lens barrel anchoring section and the support member. Additionally, the auto-focusing device includes a drive direction detection unit which detects a drive direction of the auto-focusing optical system and a drive control unit which controls the drive unit by modifying drive control parameters which are set based on the drive direction detected by the drive direction detection unit and the particular energizing characteristics of the energizing member.

摘要： A focusing control apparatus comprises a focusing information detector for detecting focusing control information regarding a focusing lens and an auxiliary lens set position detector for detecting a set position of an auxiliary lens such as a soft focus lens. A stored correction coefficient for the set position of the auxiliary lens is utilized, together with the focusing control information, in determining a drive distance of the focusing lens to achieve proper focusing. In one modification, if the auxiliary lens is manipulated and the set position thereof is changed after an in-focus state is attained in a single mode, the above process is repeated. In another modification, if the auxiliary lens is manipulated after the in-focus state is attained in the single mode, the mode is switched to a continuous mode.

摘要： A helicoid threaded tube formed by molding a synthetic resin in a split mold, comprises: a hollow cylindrical member of synthetic resin; primary threads integrally formed with the cylindrical member and helically extending on the inner or outer surface thereof and having a cross section which is substantially trapezoidal at all portions thereof except split line segments thereof where the matching surfaces of the split mold intersect with the cylindrical member; and relief thread portions centered at the split line segments and continuously extending from the primary threads with the width gradually narrowing, the relief thread portions having a height substantially equal to that of the primary threads. In such threaded tube, at those portions of its threads (relief portions) within which molding burrs will tend to occur during molding, the threads have a gradually narrowing width and a constant height. This configuration of the threads ensures that engaged male and female helicoid threaded tubes formed in accordance with the invention can achieve a smooth relative sliding movement while substantially maintaining mechanical strength. A lens barrel may incorporate such threaded tubes.
