Optical element driving device, interchangeable lens, and image-capturing device

Abstract

The present invention secures high operability with respect to an operation ring without incurring a decrease in functionality. The present invention comprises an interlinking member that is moved bythe rotational force of an operation ring, which is rotationally operated, and causes an optical element to move by transmitting the rotational force of the operation ring to the optical element. A switching mechanism that switches a movement direction of the optical element with respect to the rotation direction of the operation ring is provided to at least the interlinking member. Due to this configuration, the movement direction of the optical element with respect to the rotational direction of the operation ring is switched by the switching mechanism and the optical element is moved by therotational force of the operation ring transmitted by the interlinking member. Therefore, the optical element moves so as to follow the operation of the operation ring, movement retardation of the optical element is unlikely to occur, and a high operability with respect to the operation ring can be secured without incurring a decrease in functionality.

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
