PROBLEM TO BE SOLVED: To provide a lens operation device which is capable of switching a speed control mode and a position control mode by one lens operation device and switching to an operation form matched with each control mode, when switching the modes.SOLUTION: The lens operation device for outputting a command value corresponding to the operation angle of an operation member rotated to operate a lens device includes a return mechanism which is a return mechanism including an elastic member, a cam, and a cam follower and applies an elastic force, so as to rotate the operation member toward the predetermined return position of the rotation range of the operation member, switching means which switches an effective state where the elastic force is applied by the return mechanism and an ineffective state where the elastic force is not applied by the return mechanism, and control means which controls the lens device in the speed control mode, when the return mechanism is in the effective state and controls the lens device in the position control mode, when the return mechanism is in the ineffective state.SELECTED DRAWING: Figure 6 |
