Filed: 1987-06-04
Abstract: PURPOSE:To prevent an inadvertent mis-operation by providing a change-over mechanism so that an operating ring in common use for making a zooming operation and focusing operation is prevented from rotating at the time of an automatic focusing operation. CONSTITUTION:The change-over mechanism is constituted of a change-over ring 13, a change-over intermediate ring, a rectilinear ring 20, a leaf spring 25 and a groove 23b. To change over the operation to the automatic focusing operation, a user rotates the change-over ring 13. Then, the change-over intermediate ring 18 rotates as well and the rectilinear ring 20 moves toward the left of the figure. The leaf spring 25 is then pushed in the outside circumferential direction by this movement and a wall part 20c, by which the groove 23b of a focusing intermediate barrel 23 is disengaged from an engaging piece 25a of the leaf spring 25. The operating ring 22 is, therefore, disengaged from the intermediate barrel 23 and the intermediate barrel 23 rotates independently of the operating ring 22 so that the ring 22 does not rotate any longer. The user is thereby prevented from erroneously touching the rotating ring 22 at the time of the automatic focusing operation.
