Abstract: A display assembly consists of a display and a mount for positioning the display in a vehicle including front and back seats and a top panel. The mount includes a first shell attached to the ceiling of the vehicle and a second shell connected with the flat panel display. The first and second shells are hinged, thus allowing the second shell to move between a first position where the display is in the first shell and a second position where the screen of the display can be watched by any passenger on a back seat.

Abstract: An optical disk player for reproducing information stored on various types of optical disks, such as video disks and compact disks having diameters different from that of the video disk, for recording audio signals and for recording audio and video signals, wherein a skew sensor detects an inclination of an optical disk relative to an optical pickup, a skew servo mechanism controls the inclination of the optical pickup, relative to the optical disk on the basis of the detected inclination, a disk size detector detects the size of the disks, a disk detector detects signals, recorded in audio and audio/video compact disks indicative of the type of optical disk, and on the basis of the detected outputs from the size detector and the disk detector, the skew servo is effected continuously from the innermost track to outermost track or slightly before the outermost track when the disk is a video disk or audio/video compact disk, but wherein the skew servo is stopped at a predetermined position inwardly of the outer

Abstract: An optical disk having radially discrete main and lead-in track areas in which there are respectively recorded color video information according to one of a plurality of TV systems, such as, NTSC and PAL systems, and code data including data identifying that one TV system, is reproduced by an optical disk player including a head for initially scanning and picking up the code data recorded in the lead-in track area and then scanning and picking up the color video information recorded in the main track area.

Abstract: An apparatus for reproducing signals recorded on a selected one of first and second discs of different diameters, such as, a relatively large diameter video disc and a relatively small diameter compact disc, has a disc-transporting tray mounted for substantially horizontal movement between a first or operative position within a housing and a second or disc-inserting and withdrawing position in which the tray projects substantially forwardly from the housing through an opening at the front of the latter, the tray having first and second disc mounting portions dimensioned for receiving and holding the relatively large and small diameter discs, respectively, and the second or relatively small-diameter disc mounting portion being disposed at a front part of the tray and substantially contained within the confines of the first or large-diameter disc mounting portion for minimizing the required size of the tray, and hence the overall size of the apparatus.

Abstract: An optical disk player is provided with a casing or base which need not be substantially larger than a square inscribed by the circular perimeter of the compact disk which it plays by causing the optical pick-up to radially scan the disk along a path at a predetermined angle to the sides of the square, preferably at about 45.degree. thereto. At the outermost position of the pick-up, its object lens is centered at the outermost track on the disk, and a corner of the casing conveniently accommodates the portion of the pick-up which then necessarily extends outwardly beyond the outermost track.

Abstract: An insertion hole is formed in an objective lens holder which receives at least a distal end of a member arranged inwardly of the holder in substantially the axial direction of a support shaft.The objective lens holder can be made thin in the axial direction of the support shaft without requiring the member to be reduced in size, and an objective lens drive device can be made thin without causing degradation of sensitivity.

Abstract: In an optical disc player or other apparatus in which a light beam is directed against a record medium surface for optically reading video or audio information recorded in a track on such surface; an optical scanning assembly is provided with an objective lens interposed in the path of the light beam with its optical axis coinciding substantially with such path therethrough, a lens holder including a first tubular member having the objective lens mounted therein and a second tubular member supporting the first member for rectilinear sliding movement relative thereto in a first direction parallel to the optical axis, a base member supporting the second tubular member of the lens holder for rectilinear sliding movement relative thereto in a second direction at right angles to the first direction, for example, in a direction across or along the track in which information is recorded, first and second coils mounted on the lens holder and being independently energizable, and permanent magnets for producing magneti

Abstract: A device for supporting and positioning the objective lens in an optical reading apparatus, such as, a video disc player, comprises a first pair of parallel leaf springs attached at one end thereof to a fixed support member for motion parallel to a record medium surface. A movable frame is attached to the other ends of the first springs, and a second pair of leaf springs movable perpendicularly to the record medium surface extend from the frame, the second springs being generally parallel to and between the first pair but with their faces perpendicular to those of the first pair. The objective lens is mounted at the free ends of the second pair of springs, and is movable electromagnetically in orthogonally related directions by means of coils and magnets associated with the objective lens and with the frame.
