PURPOSE:To safely insert a recording disc to a reproducer, by providing the 1st rotating body in response to the insertion of the recording disc and the 2nd rotating body driven, as required, with a drive means consisting of a motor and the like. CONSTITUTION:The 1st rotating body 49 in response to the insertion of a recording disc is made of pipes and constituted as a coaxial construction with the 2nd rotating body 45 made of rods, and when a cartridge containing the recording disc is inserted from an insertion inlet 7a of a chassis 7, the 1st rotating body 49 and arms 50 and 51 are turned clockwise, a pantagraph mechanism 34 is operated downward and the cartridge is taken out. When a mobile body 9 is moved to the right direction with a start instruction signal of reproducing operation, the 2nd rotating body 45 starts rotation clockwise. Since the clockwise torque of the 2nd rotating body 45 is larger than the counterclockwise torque of the 1st rotating body 49 in this case, the arm 51 is pressed down, the recording disc drops and is moved to the reproducing position. |
