摘要： A lens barrel has an immovable cylindrical member adapted to be detachably attached to a camera body, and a lens holder for holding a group of focusing lenses. The holder is disposed in the member so as to be movable along an optical axis of the focusing lenses for a focusing adjustment. A manual-focusing ring, rotatably mounted on the member, is manually movable along the optical axis between an auto-focusing (AF) position and a manual-focusing (MF) position, and has a plurality of recesses circumferentially arranged and formed on an inner wall surface thereof. A drive mechanism, provided between the member and the holder to convert a rotation into a translation of the holder along the optical axis, has at least a pin which is subjected to the rotation. The pin is engaged in one of the recesses of the ring when the ring is at the MF position, such that a rotation of the ring is transmitted to the drive mechanism. The pin is disengaged from the one of the recesses of the ring when the ring is at the AF position.

摘要： An automatic diaphragm apparatus in a lens in which an aperture diameter is varied in accordance with a set diaphragm value, set by a diaphragm set ring in a first section from the maximum aperture to a predetermined intermediate aperture. The aperture diameter is kept constant regardless of the set diaphragm value of the diaphragm set ring in a second section, from the predetermined intermediate aperture to the minimum aperture. The apparatus includes a diaphragm data transmission member in the form of an arc shape lever having one end which pivots on the diaphragm set ring at an offset position from the optical axis. On the other end, a diaphragm data transmission projection is provided. The apparatus also includes a cam mechanism which is provided between the diaphragm data transmission lever and an immovable portion of the lens. The cam mechanism is for holding the position of the diaphragm data transmission projection in a constant position when the diaphragm set ring is rotated in the first section. The cam mechanism is also for rotating the diaphragm data transmission projection together with the diaphragm set ring when the diaphragm set ring is rotated in the second section.

摘要： A water-resistant structure of a lens barrel includes a sealing member that seals an annular gap between inner and outer annular members, wherein the sealing member is positioned in a vicinity of an open end of the outer annular member and is fixed to one of the inner and outer annular members to be slidable on the other of the inner and outer annular members, and a drain groove formed on the inner annular member and positioned alongside the sealing member at a position closer to the open end of the outer annular member than the sealing member. Furthermore, a frictional resistance of a first sealing member produced between a secondary annular member and a manually-rotatable annular members is greater than a frictional resistance of the second sealing member that urges one of two of the manually-rotatable annular members to follow a rotation of the other thereof when rotated.
