摘要： An optical pickup has a laser mounting surface formed around an opening portion of a laser hole while a notch groove ranging from the laser mounting surface to an operating hole is formed in a laser hole side wall portion. A fitting piece removably fitted into the notch groove is provided integrally with a metal holder which is provided for supporting a photodiode and which is locked in the laser mounting surface. The operating hole is defined between a forward end of the fitting piece and an inner end of the notch groove. A laser diode is fitted into a lock hole of the holder coaxial with the laser hole while a radiator plate is attached to the outer surface of the holder. Thus, the laser diode is held between the holder and the radiator plate.

摘要： A digital broadcasting receiver capable of receiving HD (High Definition) broadcasting, SD (Standard Definition) broadcasting and the like. In the digital broadcasting receiver, a digital broadcasting signal subjected to demodulation is separated/divided in a transport unit before being supplied to decoders. Data on a packet ID included in the digital broadcasting signal is outputted from the transport unit. An MPU determines HD broadcasting or SD broadcasting according to the data on the packet ID and when the MPU determines the SD broadcasting, it instructs the transport unit to have a set subchannel displayed and also instructs an OSD control unit to make an OSD of the subchannel.

摘要： A finite optical system that a laser beam from a light source is allowed to be directly incident on an objective lens without passing a collimate lens is employed. The reference position of the objective lens is set so that converged light from the objective lens forms a focal point on a recording layer remoter from the light source of two recording layers in an optical disk. The objective lens moves in a direction of the light source side from the reference position to perform a focusing operation and read information recorded on the recording layer nearer to the light source.

摘要： An optical pickup is provided with a substrate on which a plurality of through holes are formed, wires whose base end sides are inserted through the through hole of the substrate, a lens holder supported on the front end sides of the wires, and a retaining member provided between the substrate and lens holder. The retaining member has laterally opened concave portions for filling a cushioning material and notch portions to communicate with these concave portions. The wires are disposed so as to be stored in the concave portions and are, at a lens holder-side surface of the substrate, soldered to the substrate.
