Patent ID: 8417108

Claim:
A lens apparatus, comprising: an optical member; a driving unit for driving the optical member; a position detector for detecting a position of the optical member; an operation portion to be rotated so as to manually operate the optical member; a projection portion to be rotated interlockingly with an operation of the operation portion; a rotation detector for detecting rotation of the operation portion; a driving controller for controlling the driving unit so as to drive the optical member based on an amount of the operation of the operation portion, the amount being detected by the rotation detector; a first regulator rotatable about the same axis of rotation as an axis of rotation of the projection portion, the first regulator including a first regulation pin provided on a side of a first end of the projection portion in a rotating direction; a second regulator rotatable about the same axis of rotation as the axis of rotation of the projection portion, the second regulator including a second regulation pin provided on a side of a second end of the projection portion in the rotating direction; a first locking unit for locking rotation of the first regulator; a second locking unit for locking rotation of the second regulator; and a lock controller for controlling the locking of each of the first locking unit and the second locking unit based on the position of the optical member from the position detector and a rotating direction of the operation portion from the rotation detector, wherein the projection portion is provided between the first regulation pin and the second regulation pin in the rotating direction of the projection portion; wherein the first regulation pin and the second regulation pin are elastically connected to each other by an elastic force generated by a first elastic member, the elastic force acting in a direction in which a distance between the first regulation pin and the second regulation pin is reduced; and wherein the lock controller locks the rotation of the first regulator by the first locking unit when the optical member reaches the first end while the operation portion is operated in a direction to the first end, and locks the rotation of the second regulator by the second locking unit when the optical member reaches the second end while the operation portion is operated in a direction to the second end.
