摘要： An apparatus for preventing a leakage of light in a zoom lens barrel includes a pair of cylindrical members which are relatively rotatable and relatively movable in an optical axis direction; a drive mechanism which reciprocally moves one of the cylindrical members in the optical axis direction relative to the other cylindrical member of the pair of cylindrical members when the other cylindrical member is rotated; and helical light interception projections that are provided on opposed peripheral surfaces of the pair of cylindrical members so as not to screw-engage with each other. The helical light interception projections are adapted to prevent light from entering a space between the pair of cylindrical members while permitting the pair of cylindrical members to relatively rotate and relatively move in the optical axis direction.

摘要： An encoder for detecting a forward/reverse movement of a rotatable object includes a rotating shaft that is supported on a base and rotates in accordance with the movement of the subject, two rotating disks fixed to the rotating shaft, and two photocouplers mounted on the base which are associated with the disks. Each of said rotating disks is formed with a predetermined light modulating pattern to vary the intensity of light along a circumferential direction. Each of the photocouplers emits a light toward the rotating disk and detects the light modulated by the pattern on the rotating disk. The angular relationship between the rotating disks is selected such that the output signals from the photocouplers due to the rotation of the rotating shaft have a predetermined phase difference.
