Abstract

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.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a recording disk Fli production device that automatically transfers a recording disk onto a turntable.

(Configuration of conventional example and its problems) 1- In the conventional recording disc playback device, for example,
716! A reproducing apparatus, such as the reproducing apparatus described in No. 1168, is generally provided with a transporting means for supporting and transporting a non-recorded portion near the center hole of a recording disk (hereinafter referred to as a record). Therefore, the transfer means needs to be configured in a narrow space under the turntable, avoiding the turntable drive motor, and also requires a dedicated drive motor for the transfer means.

That is, the record is transferred by rotating the cam by a drive motor dedicated to the transfer means and pulling one collar. For this reason, the number of parts increases,
This method requires an increase in assembly man-hours, increases costs, and has the drawbacks of hindering miniaturization of recycling equipment.

(Object of the invention) The first object of the present invention is to solve the conventional drawbacks,
It is an object of the present invention to provide a recording disk reproducing device in which the configuration of a code transfer means is simplified and the number of parts and assembly steps are reduced.

(Description of an Embodiment) An embodiment of the present invention will be explained by referring to FIGS. 1 to 4.

FIG. 1 is a partially sectional perspective view of a recording disk arrangement according to an embodiment of the present invention.

In the figure, a turntable 1 on which a recording disk 1) is mounted is fixed to a turn tape motor 2.

Figure 3 (air and Figure 4 (8) are
A first stage roller 11 is connected to a turntable drive 1j11 motor 2, a conical slope 13, and a rotating ring 3.
In this state, the rotation of the turntable drive motor 2 is transmitted to the rotation ring 3, and becomes the driving force of the transfer mechanism.

3(b) and 4(b) both show that the Pranger device [10 is energized, the lever 7 is pulled, and the roller 12 is moved to the conical slope 13. Even if the state with I/I is released and the turntable drive motor 2 rotates, the rotation is not transmitted to the rotation ring 3. The upper H1 lowering of the elevating ring 5 can be performed by changing the rotational direction of the turntable drive motor 2, respectively.

(Effects of the Invention) 5. According to the present invention, since the rotational force of the turntable 1 drive motor is used for the lifting/lowering operation, there is no need for an instant-acting motor dedicated to the transfer means, which greatly reduces costs and downsizing. effective.
