摘要:
A disc reproducing apparatus comprises a disc holder for receiving a plurality of discs; a disc reproducing section including a turntable for mounting a disc, an optical pickup for reproducing information recorded on the disc, a pickup moving mechanism for moving the optical pickup in the radial direction of the disc; a reproducing section pivoting means for pivoting the reproducing section between a reproducing position and a non-reproducing position; and a disc transporting means for transporting a disc inserted from the outside to the disc holder. In particular, the disc reproducing section includes a position detecting means for detecting a position of the optical pickup in the reproducing apparatus. Further, when the disc reproducing section is in its non-reproducing position, the position detecting means is adapted to detect the position of a disc which has been transported from the outside into the apparatus.

A plurality of trays, each for holding a disc, are arranged in a disc arranging direction in a disc storage. A movable base is provided to be rotated about a shaft and a disc player having a turntable, a disc clamper and a pickup, is mounted on the movable base. A driving device is provided for rotating the movable base between a retracted position and a disc reproducing position. A lock device is provided on the chassis for engaging with the movable base at the disc reproducing position to minimize external vibrations to the movable base during disc reproduction.

A polymer composition for electrical part material comprising, (I) a polymer blend which comprises (A) at least one polymer selected from specific types of polyether imides and polyesters, and (B) at least one polymer selected from specific types of polyphenylene ethers, polyolefins, and polycarbonates, and (II) a copolymer of maleic anhydride and vinyl type compound or (II') an epoxy-modified styrene-type copolymer. The composition has excellent compatibility, heat resistance, mechanical characteristics, platability, moldability, and electric characteristics. It is an ideal material for use as an electrical part material due to its low dielectric constant and low dielectric dissipation factor at high frequency.

摘要:
An urging structure for an output shaft of a drive motor of the invention is configured by a pressing plate 31 which abuts against an end face 24a of an output shaft 24, and an urging spring 36 which urges the pressing plate in the axial direction of the output shaft 24. In the pressing plate 31, a fixing portion 32 in one end is fixed onto a chassis 21 in the vicinity of the output shaft 24, and an abutting portion 34 is disposed on the tip end of a flexible arm portion 33. A spring holding portion 35 with which an end portion of the urging spring 36 that is fixed to a spring boss 37 is to be engaged is disposed on the rear face of the abutting portion 34.
摘要:
An output of an optical sensor in the initial state, that is, when a disc is absent, is set as a reference value. A threshold for detecting the disc is calculated by adding a predetermined variation to the reference value. When the output of the optical sensor exceeds the threshold, it is determined that the disc is present.

A medium detecting device determines whether a medium is set in a device. The medium detecting device includes an optical sensor irradiates a light towards a position where the medium is possibly set, collects a reflected light, and outputs a signal based on the reflected light. A temperature sensor measures temperature around the optical sensor. A threshold selecting unit selects a threshold from among a plurality of thresholds based on the parameter. A determining unit determines whether the medium is set based on comparison of the signal and the threshold selected.
