摘要： A zoom lens includes an outer barrel driven to rotate about an optical axis of the zoom lens which includes at least one first guide groove formed on an inner periphery of the zoom lens and extending in a direction of the optical axis, and an inner barrel positioned inside the outer barrel so that the outer barrel is rotatable relative to the inner barrel about the optical axis. The inner barrel includes at least one second guide groove formed on an inner periphery and extending in the direction of the optical axis. The at least one first guide groove is defined by at least one inward projection which projects inwardly from the inner periphery of the outer barrel. The at least one second guide groove is defined by an outward projection which projects outwardly from an outer periphery of the inner barrel. The at least one inward projection and the outward projection are positioned in an annular space formed between the outer barrel and the inner barrel such that a distance between the optical axis and a surface of the at least one inward projection closest to the optical axis is less than a distance between the optical axis and a surface of the outward projection farthest from the optical axis in a radial direction perpendicular to the optical axis.

摘要： An exposure controlling device includes, an aperture diaphragm that is driven by a motorized driving mechanism to open and close, an encoder for detecting an actuation of the motorized driving mechanism comprising a photocoupler and a rotating disk mounted in connection with the photocoupler. The rotating disk rotates corresponding to the actuation of the motorized driving mechanism by less than one full turn, and the rotating disk has a first angular range where the output signal from the photocoupler does not vary even when the rotating disk rotates and a second angular range where the output signal from the photocoupler varies in cycles in accordance with the rotation of the rotating disk. A controlling unit is provided to control the motorized driving mechanism to drive the aperture diaphragm in accordance with signals received from the photocoupler. The photocoupler faces to the first angular range when the aperture diaphragm is set at an p redetermined initial position.

摘要： A light intercepting apparatus of a lens barrel has a pair of lens frames which support a pair of lens groups, with the lens groups being movable with respect to one another in an optical axis direction. The apparatus further includes a light intercepting portion which isolates an optical path between the lens groups from external light. The light intercepting portion includes a pair of annular light intercepting members which are supported by the pair of lens frames in a manner such that the pair of annular light intercepting members are movable with respect to each other in the optical axis direction. The pair of annular light intercepting members include a pair of engaging portions which define a latch portion of the light intercepting apparatus and which prevent motion of the annular light intercepting members beyond a maximum extended position of the pair of annular light intercepting members.
