摘要： An optical pickup has a support pedestal integrally formed at a rear end portion of a mounting surface of a base. A pair of left and right leg portions extend forwardly from both side edge portions of a rear end portion of a resilient plate. A fixing hole is penetratingly provided in each of the leg portions on a phantom line passing through a central axis of a photodiode and extending in a horizontal transverse direction. Each fixing screw is screwed into a threaded hole in the mounting surface through each fixing hole, so as to press the rear end portion of the resilient plate against the support pedestal.

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： An optical pickup has a pair of left and right leg portions formed integrally at both side edge portions of a rear end portion of a resilient plate. The leg portions extend forwardly along a horizontal longitudinal direction. A pair of fixing holes are penetratingly provided in the respective leg portions on a transverse phantom line passing through a central portion of the resilient plate and extending in a horizontal transverse direction and at positions spaced apart an equal interval from a longitudinal phantom line passing through the central portion of the resilient plate and extending in the horizontal longitudinal direction. A pair of fixing screws are screwed into a pair of threaded holes in a mounting surface of a base through the fixing holes, thereby fixing the leg portions to the mounting surface.

摘要： In a pickup 5 laterally moving by being guided at its one side by a main shaft 4, an inclined piece 5a tilted frontwardly and obliquely downwardly in an opening portion 1a inside a chassis 1 is opposite to the shaft 4. A screw 6 for adjusting the tilt angle of the pickup 5 is obliquely upwardly or downwardly screwed into the inclined piece 5a, and its lower part is placed inside the pickup 5. A flange-like holding portion 6A which is integral with the lower part of this screw 6 is fitted to the opposite opening edge 1b, and the bottom surface edge 6b partially abuts against the chassis 1 top surface and the edge 6b laterally moves by sliding along the top surface when the pickup 5 laterally moves. The edge 6b slides along the top surface near the edge 1b when the pickup 5 laterally moves.

摘要： A disc rotating apparatus includes a turntable for placing thereon a disc such as CD, DVD. The disc is clamped by the turntable and the disc holding frame. The holding frame is formed, at its main body, with an annular groove. The annular groove is circumferentially partitioned by a plurality of partition walls to thereby provide a plurality of accommodating portions. Each of the accommodating portions accommodates therein one or two or more steel balls. Due to rotation of the turntable or disc, each steel ball is displaced within the accommodating portion, thereby correcting for an unbalanced state wherein a center of gravity of the disc is deviated from an axis of a rotary shaft of turntable.

摘要： An optical pickup includes a semiconductor laser, a beam splitter, a collimating lens, an objective lens, an aperture and a front monitor. The beam splitter splits a light beam emitted by the semiconductor laser into transmitted light and reflected light. The front monitor detects luminous energy of the transmitted light. The front monitor is disposed near an optical axis of the transmitted light so that the following is satisfied: 1≦(S×L)/(s×f)≦6.8. S is an area of an entrance pupil of the objective lens, f is an optical distance from an emission portion of the semiconductor laser to the collimating lens, s is an effective receiving area of the front monitor, and L is an optical distance from the emission portion of the semiconductor laser to the front monitor.
