摘要： An intermediate frequency generating circuit has two frequency mixing circuits and two local oscillating circuits for applying local oscillation outputs to the two frequency mixing circuits. In the intermediate frequency generating circuit, the two local oscillating circuits are used as voltage controlled oscillators for two PLL circuits, respectively. In addition, the two PLL circuits excluding the two voltage controlled oscillators are provided in a single integrated circuit.

摘要： A rising mirror (MIR') reflects a laser beam produced by a semiconductor laser (LD') by a reflecting surface thereof to make the laser beam converge on a signal recording surface of an optical disc (Disc) through an objective lens (OL') and reflects a return beam from the signal recording surface to make a photodetector (PD) detect the return beam. A rising angle ( θ ') between the reflecting surface of the rising mirror (MIR') and the pickup's lower surface is smaller than 45 degrees. With this structure, optical parts including the semiconductor laser and the photodetector may be arranged in an optical base (OB) with the optical parts inclined to the optical base so that the optical parts are not jutted out the pickup's lower surface downwards.

摘要： A peripheral apparatus includes lower and upper resin casings made from resin by injection molding and engaged to each other so as to upwardly and downwardly cover an electrical unit. The lower resin casing is provided with a primary dent portion/a primary projecting portion formed at a primary location in the depth direction of the peripheral apparatus. The primary dent portion/the primary projecting portion dents/projects into/from a primary parting-line of the lower resin casing for the injection molding. The upper resin casing is provided with a secondary projecting portion/a secondary dent portion formed at a secondary location corresponding to the primary location. The secondary projecting portion/the secondary dent portion projects/dents from/into a secondary parting-line of the upper resin casing for the injection molding. The lower and the upper resin casings are held by each other so as to match with each other in the depth direction by engaging the primary dent portion/the primary projecting portion and the secondary projecting portion/the secondary dent portion.
