摘要： A lens barrel which can be easily switched between a manual focusing mode and an auto-focusing mode employs a motor as a drive power source for driving a switching apparatus for switching between an auto-focusing apparatus and a manual focusing apparatus. When a photographer supplies an external electrical signal, a switching operation from the auto-focusing apparatus to the manual focusing apparatus and vice versa can be performed in accordance with the forward/reverse rotational direction of the motor.

The zoom lens assembly further comprises a lens holder axially movable relative to the stationary cylindrical member and holding a certain lens unit selected from the lens units and a cam member mounted axially movable along the optical axis and rotatable about the optical axis relative to the stationary cylindrical member. The cam member is disposed between the operation member and the lens holder and has a cam connection so formed that when the cam member is rotated about the optical axis, the lens holder is moved in the direction along the optical axis and when the cam member is axially moved, the lens holder is moved together with the cam member in the direction along the optical axis. The zoom lens assembly further comprises interlocking elements for rotating the cam member about the optical axis during the time of the operation member being moved in the direction along the optical axis and for moving the cam member in the direction along the optical axis during the time of the operation member being rotated about the optical axis.

摘要： There is disclosed a zoom lens barrel of inner focusing type, simplified in structure by the use of a surface wave motor. There are provided two biasing members of different biasing forces, in such a manner that the stator member of the surface wave motor can rotate with respect to the fixed tube member and the movable member of the surface wave motor rotates integrally with the stator member in the zooming operation. Such structure allows to dispense with a mechanical clutch for selecting the focusing or zooming operation.

摘要： A lens barrel is provided with a detecting device for detecting whether a clutch device for effecting the AF mode/MF mode changeover of a focus adjusting mechanism is changed over completely to either mode. When the detecting device detects that the changeover is not complete, as due to the supply of electric power from the camera body being cut off, the clutch device is automatically brought to the change-over position of a selected mode in response to the next supply of electric power.
