    摘要： A camera having an interchangeable finder with rails or rail grooves that is detachably mounted on a camera body by being moved back and forth. The camera body has rail grooves (or rails) engaging the interchangeable finder. A viscoelastic member and a resin member or a metal member are secured in combination to the interchangeable finder of the drawing type or the camera body. When the interchangeable finder of drawing type is mounted on the body, the resin member or the metal member abuts against the camera body or the interchangeable finder of drawing type to thereby establish an environmental seal.

    摘要： An optical pickup device includes a first laser element that emits first laser light, a second laser element that emits second laser light of which the wavelength is longer than that of the first laser light, an optical path composition element that composes the first laser light and the second laser light to one optical path, a wavelength selective element that acts on the composed first or second laser light; and an objective lens that condenses the first laser light and the second laser light on an optical disk. The magnitude of the power of the wavelength selective element as a lens with respect to the second laser light is larger than the magnitude of the power of the wavelength selective element as a lens with respect to the first laser light. Accordingly, it may be possible to reduce the optical pickup device and the optical disk apparatus in size.

    摘要： The invention provides a tracking control device, a tracking control method, and an optical disc apparatus that enable to stably perform the tracking control, and reduce an influence of stray light from the other layer on the tracking control. A sub push-pull signal correcting section corrects a sub push-pull signal to be generated from returning light of a sub beam in such a manner that a track crossing component of a main push-pull signal to be generated from returning light of a main beam, and a track crossing component of the sub push-pull signal to be generated from the returning light of the sub beam are canceled. A low pass filter reduces a high frequency component of the sub push-pull signal corrected by the sub push-pull signal correcting section. A subtractor subtracts a sub push-pull signal passing the low pass filter from the main push-pull signal to thereby generate a tracking error signal.

    摘要： An optical head includes a plurality of light receiving areas, which receive a first type of reflected rays where zero-order and first-order components of the light diffracted by a track are superposed one upon the other to generate a light quantity signal representing the quantity of light of the first type of reflected rays, and a non-light-receiving area, which is provided between the light receiving areas so as not to receive a second type of reflected ray consisting essentially of the zero-order components. As measured in a first direction in which the light receiving areas are arranged, a gap between the light receiving areas is longer than the width of the non-light-receiving area. The optical head further includes a tracking error signal generating section for generating a tracking error signal based on the light quantity signal.
