Optics Drivers, Interchangeable Lenses, and Cameras

Abstract

In order to ensure high operability with respect to the steering ring without causing functional degradation. comprising an interlocking member configured to be operated by a rotational force of a steering ring that is rotated and manipulated to operate the optical element by transmitting the rotational force of the steering ring to the optical element, and at least on the interlocking member is provided a switching mechanism that is It is configured to change the operating direction of the optical element relative to the rotational direction of the operating ring. With this configuration, since changing the operating direction of the optical element with respect to the rotational direction of the manipulation ring is performed by the conversion mechanism, and the optical element is operated by the rotational force of the manipulation ring transmitted by the interlock member, the optical element is operated so as to follow the direction of manipulation With the manipulation performed by the ring, operation delay of the optical element rarely occurs, and high operability with respect to the manipulation ring can be ensured without causing a decrease in function.

Description

technical field [0001] The present technology relates to the technical field concerning an optical element driving device that operates an optical element by a rotational force of a steering ring that is rotationally manipulated, and an interchangeable lens and an imaging device including the optical element driving device. Background technique [0002] In a structure used in photographing performed by various imaging devices such as video cameras and still cameras, interchangeable lenses, and the like, an optical system including various optical elements such as lenses and lens groups is disposed therein. [0003] In this structure, the optical element is moved in the optical axis direction (axial direction) by the optical element driving device, and zooming, focusing, and the like are performed, for example. In addition, there is also a structure in which a blade member such as an optical element such as a diaphragm is operated by an optical element driving device, and the...

Problems solved by technology

[0008] When the function to be performed varies depending on the direction of rotation of such a steering ring, when in use, there is a fear of malfunctions such as wrong manipulation with regard to the direction of rotation performed on the steering ring and missed shooting opportunities, and there is a possibility that good operability cannot be ensured sexual possibility
