摘要： Remote control apparatus for lifting the tone arm of a phonograph from a record being played and immediately repositioning the tone arm to recommence the playing of the same record is disclosed. The disclosed apparatus includes a tone arm repositioning ramp which is tiltable about a horizontal pivot affixed to the deck of the phonograph from a rest position to a fully raised position. The disclosed apparatus also includes a power drive for tilting the tone arm repositioning ramp into its fully raised position and then returning the tone arm repositioning ramp to its rest position under the control of a manually operable switch located remotely from the phonograph. The tone arm repositioning ramp is so located with respect to the tone arm that whenever a record is being played on the phonograph and the ramp is driven from its rest position to its fully raised position the ramp lifts the tone arm from the record. After being thus lifted from the record, the tone arm slides down the ramp until it bears against a stop affixed to the ramp. The position of the stop is such that when the ramp returns to its rest position from its fully raised position the tone arm is deposited on the record with its stylus in the exposed record groove just before or at the beginning of the musically modulated position of the record groove. The disclosed apparatus also includes an arresting device which halts the tone arm repositioning ramp in its fully raised position, and thus maintains the tone arm withdrawn from the record, so long as the manually operated switch is depressed.
