摘要： A zoom lens barrel includes a cam ring which is driven to rotate; a first lens frame which is positioned around the cam ring, supports a frontmost lens group of a zoom lens system, and includes a first cam follower; a light-shield exterior ring positioned around the first lens frame, and includes a second cam follower; and first and second outer cam grooves formed on an outer peripheral surface of the cam ring so that the first and second cam followers are engaged in the first and second outer cam grooves, respectively. The second cam follower is engaged in the second outer cam groove through a linear guide slot formed on the first lens frame. Zooming ranges of the first and second outer cam grooves are shaped so as to move the first lens frame and the light-shield exterior ring in the same moving path.

摘要： In an optical system comprising a light source section consisting of a semiconductor laser and a collimator lens, an objective lens for focusing a light beam on an optical disk, a beam splitter for separating part of the light beam reflected from the optical disk, a condenser lens, and a photosensor for detecting the separated light beam to produce a focusing and a tracking error signal, a plane parallel plate is provided between the light source section and the beam splitter. By rotating the plane parallel plate with an adjusting mechanism, the light beam undergoes a parallel shift, so that the intensity distribution of light being incident on the objective lens is varied and a tracking offset due to a deviation of the optical axis of the output light from the light source section can be compensated for. The plane parallel plate may be disposed between the beam splitter and the condenser lens.

摘要： A reflected light beam from a magneto-optic disk is reflected by a first and second reflective element toward a signal detecting system. The first reflective element reflects the reflected light from the magneto-optic disk and gives a phase difference into the light beam. The second reflective element reflects the reflected light by the first reflective element toward the signal detecting system, and gives a phase difference which has the same amount as the phase difference caused by the first reflective element, but with the inverse sign thereof.
