PURPOSE:To prevent double loading, by interlocking the material to stop the disc carrying with the vertically driving means of the turntable. CONSTITUTION:By insertion of record disc 50, actuator 33 is operated, and insertion detecting switch S2 is turned on. In response to the turn-on output of switch S2, phono motor M1 16 starts rotating, and down plunger P1 35 is excited, and stage 32 falls, and rise part 32a, actuator 33, switch S2, and so on which break the carrying path of the record disc are evacuated from the carrying path. The fall completion of stage 32 is detected by fall detecting switch S3, and the carrying motor is operated to carry in the record disc. At the positioning completion of the record disc, detecting switch S4 is turned on, and excitation of down plunger P1 35 is released. As a result, stage 32 and turntable 17 are energized by springs 34 and 18 to rise. |
