摘要： An autofocus lens barrel has an optical system shifter for shifting a focusing optical system forward and backward in the direction of the optical axis, a driven pulley rotatively driven around the optical axis for actuating the optical system shifter, and a driving pulley which is driven by receiving a driving force. The driving force is transmitted from the driving pulley to the driven pulley by means of a belt. Preferably, an idler pulley should be proved at a position substantially symmetrical to the driving pulley with respect to the optical axis, and the driving force is transmitted from the driving pulley to the driven pulley and the idler pulley by means of a belt.

摘要： A lens barrel having a cam cylinder formed with a cam groove having two side surfaces and a lens holding frame provided with a cam follower inserted into the cam groove and guided in contact with one of the two side surfaces. The cam follower includes an elastic member in elastic contact with the other side surface of the cam groove to absorb a play between the cam groove and the cam follower. A distance between the two side surfaces of the cam groove becomes smaller in a direction of depth of the cam groove; and there is a clearance between the cam follower and the other side surface.

摘要： The mounting of an interchangeable lens having a predetermined or lesser back focus and an intermediate adapter is limited by camera bodies and the intermediate adapters. A camera system has two kinds of bodies having metal backs of the same dimension and body side mounts of the same shape, a plurality of interchangeable lenses having a common lens side mount engageable with the body side mounts, and a plurality of intermediate adapters between the interchangeable lenses and the camera bodies. The first body has an escape portion in the body side mount over the mounting range of the interchangeable lenses or the intermediate adapters so that the mounting of all the interchangeable lenses and all the intermediate adapters may be possible. The second body has a flange portion in the body side mount so that the mounting of an interchangeable lens having a predetermined or greater back focus and an intermediate adapter mountable only on this interchangeable lens may be possible.

摘要： A mounting device for mounting an optical device (for example, a lens barrel) on a support structure (for example, a tripod). The mounting device has a rotatable ring unit and a mounting seat integrally formed as a single unit, and allows the support structure to be attached to either the ring unit or the mounting seat. The ring unit is attached to the optical device and has a support member mounting device arranged thereon for connecting the ring unit to the support structure. The ring unit is rotatable to align the support member mounting device for connection to the support structure. The mounting seat extends from the ring unit and is integrally formed with the ring unit as a single component. The mounting seat has at least one support member mounting device arranged thereon for connecting the mounting seat to the support structure.
