摘要： A simplified acoustic disk record playback apparatus is disclosed having a battery-powered motor driving a turn table through a belt and pulley system. The turn table is centrally mounted on a rotating shaft. Overlying the turn table is a disk record which may have a plurality of grooves starting on its periphery. The turn table is spring biased towards a tone arm and associated record pickup stylus. The tone arm pivots horizontally, parallel to the plane of the disk record, but is held vertically by an overlying speaker cone, and is spring biased to a beginning playback position. The tone arm carries a center gear locking member on that side proximal to the turn table rotating shaft. A center gear is mounted on the turntable rotating shaft coplanar with the tone arm. Located on the turn table center, or rotating, shaft beneath the center gear is a two piece can assembly which lengthens when twisted. As the tone arm reaches the end of the disk record playback, the center gear locking member locks the center gear to stop the rotation of half the cam assembly, subjecting the cam to twisting and lengthening, thereby countering the spring bias of the turn table and allowing the tone arm to return to a playback position.

摘要： A sound reproducing device is disclosed in which an index tracking portion formed on a record disc consists of a notch on the continuous flange of rotational periphery of a record disc unit. A center pin of the device is normally urged outside of a casing by a spring which also urges an index setting arm with a push button type index setting rotary knob supported on the tip end of said center pin. An index setting portion consists of a plurality of openings formed in the casing and arranged along the rotational plane of said record disc unit. The index setting arm has a resilient engaging hook on its lower tip end, the engaging hook directed toward the rotational cetner of the record disc unit. The engaging hook engages with the flange of the record disc unit where a specific index setting portion is selected by rotation of the push button type index setting knob. Pushing the index setting knob down makes the engaging hook pass through an index setting openings. The center pin keeps a speaker unit out of engagement with a pickup such that the pickup returns to the starting point of sound reproduction. The engaging hook returns through the index tracking portion when the index tracking portion comes on the engaging hook by rotational movement of the record disc unit, causing the center pin to retract so as to impart stylus pressure to the stylus by returning the speaker unit by a stylus pressure spring.

摘要： An index portion of a record disk unit is formed by cutting out a portion of a flange which is formed continuously along a peripheral edge of the record disk unit. When one of selection rods is pushed against a spring which urges the selection rod in a retreating direction, to rotate a stylus presssure release actuating wheel, an engaging member, formed on the selection rod, is elastically deformed by the edge of the flange and rides over the flange into engagement therewith. When the index portion of the record disk unit comes around to a position coincident with the engaging member, the engaging member is allowed to pass through the cut-out portion of the index portion, to thereby return the selection member to its original position by a spring force to be applied a stylus pressure on a pickup.

摘要： In a pickup arm drive device of a record player capable of automatically selecting a desired music on a record disc on which a plurality of pieces of music are recorded, at least two inter-music sensors are arranged near a stylus on the pick-up arm to detect inter-music spaces on the record disc. The outputs of the sensors are subjected to processing and by using the resultant processed outputs, the driving of the pickup arm is switched from "lead-in" or "return" operation to an inter-music position servo operation. Therefore, the stylus of the pickup arm can be lowered exactly onto the inter-music space on the record disc even if the record has an eccentricity or warp.

摘要： A separation band detecting circuit is used in an automatic program selection record player which has a photodetector which moves together with a tone arm and comprises a light-emitting element for emitting light against the surface of the record and a photosensitive element for receiving the light reflected at the record surface and producing an output in accordance with the light quantity of the received reflected light. The detecting circuit comprises an operational amplifier supplied with the output of the photodetector to its one input terminal, and a time constant circuit connected to the other input terminal of said operational amplifier, for giving a threshold level with respect to the operational amplifier and giving a time constant with respect to the level fluctuation in the threshold value. The time constant circuit varies the threshold level with a time constant, according to an input signal level to the one input terminal of the operational amplifier. The operational amplifier inverts its output when the relationship between amplitudes of the input signal level and the threshold level reverses.

摘要： A pickup arm controlling apparatus for an audio record or a video disk player, comprising an optical detecting device provided at the foremost end portion of a pickup arm for detecting a non-recorded groove portion, arranged so that a reproduction of the disk is performed by causing, due to the detecting device, the pickup arm to make a lead-in motion while the detecting action is being performed, and stopping the lead-in motion of the pickup arm upon detection of a predetermined non-recorded groove portion, and causing a stylus to descend onto the surface of the disk, wherein arrangement is provided so that, after the pickup arm has ceased its motion during the lead-in action, the pickup arm is forced to make a reversed run only for a trifle amount or distance to thereby compensate for an overshooting which could occur during the lead-in motion of the pickup arm. This trifle amount of the reversed run can be varied. Also, during a manual lead-in operation, the overshoot-compensating action is released.

摘要： A one-way clutch is provided between a constant torque spring motor and a turn table. A locking projection in the one-way clutch acts to engage, through a rotatable locking piece, a locking face facing to the opposite direction of rotation of the record disc for reproducing sounds.By virtue of this locking driving force of the constant torque spring motor is transmitted to the turn table, while in the winding operation, applied force can be released by the slant face inclined toward the direction of rotation of the record disc and thereby can be disconnected with the turn table. Due to this simple construction, a one-way clutch applicable to this kind of constant torque spring motor for use in a sound reproducing device can be easily fabricated and assembled. In order to prevent any harmful frictional slippage of the pickup on the face of record disc by reverse turning of an indexing disc, another one-way clutch of similar construction is disposed between the indexing disc and the face plate.

摘要： There is described, among other things, an accessory for a phonograph record disc which has a center hole axially of label portion of the disc. The accessory comprises a sheet which is of circular annular shape and has a diameter not substantially greater than the disc label portion. One side of the sheet carries adhesive for affixing the sheet to the label portion of the record concentric to its center hole. The opposite side of the sheet carries an annular band which is positioned concentric to the center of the sheet. The annular band is defined by a magnetic recording medium. The magnetic recording medium facilitates the placement of information on the record disc which can be read and used by a programmable record player.The invention also describes a phonograph record having a central label portion and a circular hole through its axis. The record includes a band of magnetic recording medium affixed to the label portion concentric to the hole.
