摘要： A retracting mechanism of a zoom lens barrel includes first, second and third lens groups, wherein the first and third lens groups are integrally moved along an optical axis during variation of a focal length, and wherein at least one of the first and third lens groups is moved relative to the other to reduce a distance therebetween when the zoom lens barrel is fully retracted. The retracting mechanism includes first, second and third lens group moving rings; a cam mechanism for independently moving the first and second lens group moving rings; a second lens group support frame; an intermediate member fixed to the second lens group support frame; and a biasing device for biasing the third lens group moving ring away from the first lens group moving ring. The biasing device functions between the intermediate member and the third lens group moving ring.

摘要： A lens barrel includes first and second lens groups guided in an optical axis direction without rotating about the optical axis, first and second support frames which support the first and second lens groups and include first and second cam followers, respectively; and a cam ring which is rotatable about the optical axis and includes a cam groove. The cam groove is formed as a continuous groove and includes first and second groove portions via which the first and second cam followers are guided to move the first and second lens groups, respectively. One of the first cam follower and the second cam follower enters one of the first groove portion and the second groove portion after passing through the other of the first groove portion and the second groove portion in a preparation stage of the lens barrel.

摘要： A lens barrel includes a movable lens frame and a cam ring for moving the movable lens frame in a direction of an optical axis via a movement of the cam ring which is rotatable about the optical axis and movable in the direction thereof. The lens barrel includes a stationary ring provided around, and coaxial with, the cam ring; a rotatable ring provided around, and coaxial with, the stationary barrel, the rotatable ring being driven to rotate about the optical axis. A cam follower extends radially outwards from the cam ring, and a cam through-slot and a rotation transfer groove which are formed on the stationary ring and the rotatable ring, respectively, so that the cam follower is engaged in the cam through-slot and corresponding rotation transfer groove. The cam through-slot includes a linear and an inclined slot portion.

摘要： Lens barrel has a lens supporting frame to which a frontmost lens group is fixed, a first moving frame to which the lens supporting frame is engaged, a second moving frame to which a rear lens group which is positioned behind the frontmost lens group is supported, and a support frame movement mechanism for moving the first and second moving frame between ready-to-photograph positions and accommodation positions behind the ready-to-photograph positions in an optical axis direction. The support frame movement mechanism makes the first moving frame and the second moving frame rotate about the optical axis relative to each other with the lens supporting frame and the second moving frame being in contact with each other when the first moving frame and the second moving frame are positioned in the vicinity of accommodation positions. One of the lens supporting frames includes a low-frictional portion provided on a contacting surface thereof.

摘要： A disk cartridge loading system for a disk drive. The loading system includes a disk cartridge holder, a drawing mechanism, a draw-in sensor, a loading sensor, and a controller. The drawing mechanism engages a partially inserted disk cartridge to fully draw the disk cartridge into the disk drive, so that the disk cartridge is accommodated in a disk cartridge holder. A holder moving mechanism moves the disk cartridge holder to a loading position, so that at least one of a data reading operation and a data writing operation can be performed. A draw-in sensor is provided to detect the partial insertion of the disk cartridge, while a loading sensor detects when the disk cartridge is located at the loading position. A control unit controls the drawing mechanism and the holder moving mechanism, based on a first signal produced by the draw-in sensor and a second signal produced by the loading sensor.
