Title: 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 by the 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 the rotational 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.
