Abstract
A lens barrel includes an optical lens unit, a manual operation member for manually moving the optical lens unit in an optical axis direction, a motor member for driving the optical lens unit in the optical axis direction, a motor operation member for actuating the motor member, the motor operation member being arranged to output a signal relating to an operation of the motor operation member, and the motor member being arranged to be driven according to the signal, a transmission mechanism capable of driving the optical lens unit in the optical axis direction by concurrently transmitting an operation force of the manual operation member and a driving force of the motor member to the optical lens unit, and a setting member for setting the motor member into an inoperative state.
Claims14
A lens barrel comprising:
- an optical lens unit;
- a manual operation member for manually moving said optical lens unit in an optical axis direction;
- a motor member for driving said optical lens unit in the optical axis direction;
- a motor operation member for actuating said motor member, said motor operation member being arranged to output a signal relating to an operation of said motor operation member, and said motor member being arranged to be driven according to the signal;
- a transmission mechanism capable of driving said optical lens unit in the optical axis direction by concurrently transmitting an operation force of said manual operation member and a driving force of said motor member to said optical lens unit;
- and
- a setting member for setting said motor member into an inoperative state.
