摘要: A record (12) comprising a convex protrusion (12a) at its center, one or more protrusions (12b) extending perpendicularly from the plane of the record at its circumferential edge, and a recording area between the center and the circumferential edge. The protrusions engage similar indentations (3b, 3e) formed in a turntable to facilitate centering and holding the record for playing and to prevent rotational slippage.

摘要: A recording media selecting mechanism has a recording media selecting knob which is sufficiently large so that the recording media selecting operation can be easily performed. A starting member or, alternatively, a driving source is utilized to actuate automatically a lifting operation of recording media sheets which are contained in a recording media package so that the recording media sheets are not required to be lifted using a manual lever.
