PURPOSE:To simplify the constitution of a record carrying means and to reduce the number of parts and the number of manhour required for assembling by transmitting the power of a driving means to the carrying means and operating the record carrying means. CONSTITUTION:The roller 11 of an interlocking means is abutted on a conical surface provided to a turntable driving motor 2 and another conical surface provided to a rotary ring 3. The rotation of the turntable driving motor 2 is transmitted to the rotary ring 3 and it is used as a motive force for a record carrying mechanism. In non-abutting case, the rotation of the motor 2 is not transmitted to the rotary ring 3 even when the motor 2 rotates. Moreover, an elevating ring 5 can be moved in the ascending and descending directions when the rotating direction of the motor 2 is changed. Since the rotating force of the motor 2 is used for making the ascending and descending operations of the elevating ring 5, no driving motor which is exclusively to be used for the carrying means is required. Therefore, the record carrying means can be simplified and, as a result, the number of parts and man-hour required for assembling the record carrying means can be reduced. |
