LENS BARREL

摘要

An interchangeable lens has a lens frame holding a movable lens group, another lens frame holding another movable lens group, one actuator that drives one lens frame, and the other actuator that drives the other lens frame. A first yoke forming a magnetic circuit of the one actuator and a second yoke forming a magnetic circuit of the other actuator are disposed away from each other in an optical axis direction, and a nonmagnetic member is interposed between the first yoke and the second yoke.

主权项

1. A lens barrel in which a first movable member holding a first lens group and a second movable member holding a second lens group are arranged in an optical axis direction and are movably stored, comprising:
a first actuator in which a first magnetic circuit is constituted of a first coil, a first magnet disposed to face the first coil and a first yoke and which moves the first movable member in the optical axis direction by the first magnetic circuit; and a second actuator in which a second magnetic circuit magnetically independent of the first magnetic circuit is constituted of a second coil, a second magnet disposed to face the second coil and a second yoke and which moves the second movable member in the optical axis direction by the second magnetic circuit, wherein the first yoke is disposed away from the second yoke as much as a predetermined distance in the optical axis direction.
