Zusammenfassung: | PURPOSE:To execute other operation automatically after the reproducing operation of sound record by moving a center shaft supporting a record disc in the axial direction to disconnect power transmission from a driving motor for the record disc to an external output shaft. CONSTITUTION:When a start bar 11 is pushed, a pickup 6 is restored to the reproducing start point (a) of the record disc 3. When the start bar 11 is released, stylus pressure is applied to the pickup 6. If a switch is turned on under said state, the motor 9 is driven, the record disc 3 is rotated and the record is reproduced. At that time, a driving wheel 14 is released from a driven wheel 15, so that power is not transmitted to an external output shaft 12. When the pickup 6 reaches a reproducing end point 3b and falls into a stylus drop recessed part (d), the center shaft 2 is moved upwards by the force of a stylus pressure spring 10. Consequently, the driving wheel 14 is meshed with the driven wheel 15 and the power of the motor 9 is transmitted to the external output shaft 12. Thus, other operation is automatically executed successively to the reproducing of the sound record. |
