Abstract

PURPOSE:To make it possible to control automatically a lead-in position and the rotational frequency of a turntable by selecting two positions, differing in hooking part, corresponding to the size of a record disk. CONSTITUTION:Detecting member 13 projecting from turntable 11 is fitted one end of hook member 14. At both the ends of hook member 14, two projecting hooking parts 15 and 16 differing in distance from the center of turntable 11 are formed and hooking part 15 is normally projecting downward from turntable 11 by the displacing force of spring 17. Now, a LP record disk, when placed on table 11, pushes detecting member 13 and hooking member 14 turns clockwise to let 2nd hooking part 16 project downward from table 11. An EP disk, on the other hand, makes detecting member 13 stay as it is. Thus, hooking parts 15 and 16 projecting downward selectively according to the size of a record disk puts the rotational-frequency change-over switch of table 11 into motion or control a lead-in position.
