Abstract: A record player includes a turntable, a drive motor, a non-contact transmission mechanism, a tone arm, and a housing. The non-contact transmission mechanism includes a drive-side rotor and a magnetic member. The drive-side rotor is rotated by a driving force of the drive motor. The drive-side rotor is formed of a permanent magnet. The magnetic member is constituted of a soft magnetic body. The turntable is rotated according to the rotation of the drive-side rotor by an attraction force acting on the magnetic member from the permanent magnet.

Abstract: A support leg for an equipment case is made of a support leg main body and a stand base. The main body defines a concave (recessed) portion in the bottom thereof. A spire head portion that defines a spike is disposed in the concave portion so the spike does not extend beyond the bottom of the main body. Optionally, cushioning material is attached to the bottom of the main body to protect a surface on which the support leg breasts, while the support leg is used without the stand base. Optionally, the stand base is loosely attached to the support leg, such as by one or more screws.

Abstract: To provide support leg devices for an equipment case which are structured so as to improve workability and also so as not to scratch a rack at the time of setting up an audio equipment or the like on the rack, and are further capable of taking measures for safety of fingers at the time of installation work; moreover, which are structured so as to be fastened to the equipment case with a high rigid structure permitting to eliminate vibration and resonance effectively; and which are further improved in design quality; and furthermore, which permit one-point supporting by spike bodies onto stand bases only by setting up the audio equipment or the like, and thereby facilitate the setting work into an installation space with poor dead space.

Abstract: A recording medium loading device includes a holder into which a cartridge containing a disk-like recording medium is inserted from a predetermined side, a cartridge retraction mechanism that retracts the cartridge when the cartridge is inserted to an insertion detection position inside the holder, and a prevent mechanism, the prevent mechanism being moved in a direction of insertion of the cartridge by the cartridge retraction mechanism when the cartridge is inserted from the predetermined side.

Abstract: A pulley adapted to be press-fit on a driving shaft has projections having vertex portions with flat surfaces formed on an inner peripheral surface which is defined by a center hole of the pulley. The flat surfaces of the projections make pressing contact with an outer peripheral surface of the driving shaft at a band-shaped contact area (or surface) extending spirally or concentrically along a longitudinal direction of the pulley.

Abstract: In a data transfer apparatus such as a Winchester disk drive wherein a transducer or transducers fly over a magnetic disk surface or surfaces during data transfer therewith, a retractor mechanism is provided which coacts with a transducer positioning mechanism for causing the transducer to land on a head landing track disposed radially and inwardly from a series of concentric data storage tracks on the disk, as when the apparatus is electrically turned off. The retractor mechanism includes a spring or like energy storage element in which energy is stored when, with the apparatus powered on, the transducer is first transported by the positioning mechanism from the head landing track to the outermost home track on the disk for initialization.
