摘要： A spindle adapter apparatus having two stop plates separated by a distance equal to the thickness of one record, each of said stop plates being movable back and forth between an extended position in which it can support one or more records and a retracted position in which records can be slid over it without interference. The location of the stop plates is controlled by an operative shaft which is axially movable among three axial positions and rotatably movable between two rotary positions. If the operative shaft is moved in an appropriate sequence by external means, the stop plates are caused to move in a manner permitting the following events in sequential order: (1) a stack of records is first supported entirely by the lower stop plate, the upper stop plate being in its retracted position, (2) the upper stop plate is then moved from its retracted to its extended position, assuming the support of all but the bottom record, (3) the lower stop plate is moved to its retracted position, permitting the bottom record to fall onto a turntable, and (4) the lower stop plate is moved to its extended position while the upper stop plate is moved to its retracted position, permitting the remaining records to drop from the position in which they had been supported by the upper stop plate to a position in which they are supported by the lower stop plate.
