<p>In a phonograph record player, a control mechanism having an automatic lead-in mode of operation for effecting lead-in movement of a tone arm from an elevated rest position outside the perimeter of a turntable to a selected set-down position on a record supported by the turntable so as to commence a play operation, and an automatic return mode of operation for effecting a return movement of the tone arm to its rest position upon the termination of the play operation, is further provided with a repeat selector which, when activated, establishes an automatic repeat mode of operation in which an automatic lead-in mode of operation is initiated upon the completion of each automatic return mode of operation, and with a lamp or other indicator energized when said repeat selector is activated to indicate that the automatic repeat mode of operation has been established. The control mechanism is also provided with a manual operation selector which is preferably actuated in response to the movement to a respective position of a record size selector otherwise functioning to determine the set-down position of the tone arm in the automatic lead-in mode of operation, and which, when actuated, inhibits or prevents the establishment of the automatic lead-in, return and repeat modes of operation so as to permit the manual lead-in and return movements of the tone arm.</p> |
