LENS BARREL

摘要

A lens barrel includes a lens drive ring which moves a movable lens group along an optical axis, a first inputter including an actuator and generating a first rotational input, a second inputter which generates a second rotational input, a power transmission clutch including a first input member, a second input member and an output member, wherein the first input member is rotatable and is associated with the first inputter, the second input member is rotatable and is associated with the second inputter, and the output member is rotatable and is associated with the lens drive ring; and a load controller. When the second rotational input, which is generated by the second inputter, is applied to the second input member to thereby cause the first input member to rotate, the load controller exerts a rotational load on the actuator.

1. A lens barrel comprising:
a lens drive ring which moves, by rotating, a movable lens group along an optical axis; a first inputter which includes an actuator and generates a first rotational input; a second inputter which generates a second rotational input; a power transmission clutch which includes a first input member, a second input member and an output member, wherein said first input member is rotatable and is associated with said first inputter, wherein said second input member is rotatable and is associated with said second inputter, and wherein said output member is rotatable and is associated with said lens drive ring; and a load controller, wherein, when said second rotational input, which is generated by said second inputter, is applied to said second input member to thereby cause said first input member to rotate, said load controller exerts a rotational load on said actuator.
