Abstract: A casing which accommodates an electric circuit for generating sounds of different tones or voice sounds has a recess 11 defined in its upper panel and a loudspeaker 12 disposed therein and mounted on the upper panel for reproducing and radiating sounds or voice sounds. A plurality of tone plates can selectively be placed, one at a time, in the recess. Each of the tone plates has dots and a bar code indicative of a sound or voice sound of its own. When one of the tone plates is inserted in the recess, the dots or bar code is detected by a sensor in the recess, and the electric circuit enables the loudspeaker to reproduce and radiate a tone or voice which is indicated by the inserted tone plate.

Abstract: An input device is provided with an operating member to be freely moved within a predetermined area by an external input force, such as a force exerted through an operator's finger or hand, for inputting given information by operating the operating member.

Abstract: A record player with a turntable mounted for rotation in a substantially fixed horizontal plane on a chassis and a tone arm for reproducing signals recorded on the surface of a record disc which faces upwardly when the disc is rotatably supported on the turntable, is provided with a record turn-over mechanism comprised of a support structure, for example, in the form of lever assemblies, mounted on the chassis for swinging between raised and lowered positions about an axis which extends parallel to a diameter of the turntable and is disposed to one side of the latter, a pair of spaced apart gripping devices directed inwardly towards each other from end portions, respectively, of the support structure and being axially movable between gripping positions at which the gripping devices are engageable with diametrically opposed locations on the periphery of a record disc and released positions, the gripping devices also being turnable relative to the support structure about a common axis parallel with the axis of

Abstract: A gramophone record player comprises a movable body to be placed on a stationary gramophone or phonograph record, a drive in the movable body to drive the movable body on the record, a sound pick-up arranged to be energized by the sound groove of the record and mechanically connected to the movable body, and a gramophone record sound groove following guidance member coupled to the movable body in such a manner that the pick-up traces along the sound groove of the record.

Abstract: In a record player in which the friction of the pickup stylus in respect to a rotated record disc results in a so-called inside force acting to turn the tone arm in the inward direction with the magnitude of such inside force varying in accordance with the stylus position in the spiral record groove; an inside force cancelling device includes a cam follower, for example, in the form of a roller, spaced radially from the turning axis of the tone arm and coupled with the latter to move in an arcuate path with the tone arm, and a cam member having a cam surface extending along such arcuate path and being inclined in respect to the direction of movement of the cam follower so that the urging of the cam member against the cam follower, for example, by the force of gravity acting on a weight mechanically coupled to the cam member, causes the inclined cam surface to exert a force on the cam follower in the direction for opposing the turning of the tone arm by the inside force.

Abstract: A cartridge shell for supporting a phonograph cartridge on the end of a tone arm is provided which is formed of a sheet of carbonaceous fibers bonded together by a synthetic resin into an L-shaped member having a horizontal leg portion and a vertical leg portion. A metal plate also of L-shape covers the upper surface of said horizontal leg of said carbonaceous fiber sheet and also covers the outer surface of said vertical leg of said carbonaceous fiber sheet. The metal plate intimately engages said fiber sheet and is firmly attached thereto. The cartridge shell is made light in weight with high internal loss and is also quite rigid. This is obtained by the use of the carbonaceous fibers bonded together by a synthetic resin and secured to a metal cover plate by a suitable adhesive or by a heat-press.
