摘要： An objective lens corresponding to a BD beam light, and an objective lens corresponding to a DVD/CD beam light are arranged parallel to an optical disc. One rising mirror is arranged in a tilted manner on a side opposite to the optical disc of the objective lenses. A first film for reflecting the BD beam light emitted from a laser diode and making the beam light enter the objective lens and transmitting the DVD/CD beam light emitted from a laser diode is arranged on one of the parallel surfaces of a transparent substrate of the rising mirror. A second film for reflecting the DVD/CD beam light transmitted through the first film and the transparent substrate and making the beam light enter the objective lens is arranged on the other surface. An incident optical axis to each objective lens of the BD beam light and the DVD/CD beam light is branched with the rising mirror.

摘要： The present invention provides an optical pickup device in which a liquid crystal device is easily attached, mass productivity is high, a movable actuator is light, excellent response can be obtained and, moreover, the liquid crystal device can be easily controlled. In an optical pickup device in which laser beams emitted from light sources pass through a collimator lens and an objective lens and are condensed to a surface of an optical disc, a liquid crystal device for correcting spherical aberration of an outgoing light from the objective lens is provided in front of the collimator lens when viewed from the light sources. The liquid crystal device has a single electrode formed in a wide range in each of a pair of substrates facing each other while sandwiching liquid crystal. A predetermined voltage is applied to the electrode to uniformly change the refractive index of the whole electrode region in the liquid crystal device and make air conversion length between the light sources and the collimator lens variable, thereby changing the degree of parallelization of outgoing light from the collimator lens and correcting spherical aberration.

摘要： An optical pickup includes a radiating plate made to abut against a rear surface of a laser diode by positioning an engaging hole provided penetratingly in a central portion of the radiating plate concentrically with the laser diode. Slits are formed in the radiating plate to form a pair of tongues in the manner of point symmetry about an axis of the engaging hole. Screw insertion portions formed in the respective tongues are communicates with the slits. As screws are passed through the screw inserting portions and are screwed in, the radiating plate is secured to the base. When the screws are screwed in, the axis is positioned on a phantom line connecting points of application of force generated at proximal end portions of the tongues. Distances from the axis to the respective points of application of force are set to be substantially identical.

摘要： A soft adhesive agent whose force occurring at the time of curing is small is applied between a rib and a PD, and after the curing of the soft adhesive agent, a hard adhesive agent whose force occurring at the time of curing is large is applied between the rib and a plate. Thus since a sensor portion is fixed to a main-body base with two kinds of adhesive agents including the soft adhesive agent and the hard adhesive agent, it is possible to suppress the positional offset of the sensor portion at the time of its attachment, and it is possible to sufficiently ensure reliability with respect to the temperature change as well.
