The present invention relates to a record plate automatic insertion and ejection device of a turntable, and in particular, a drive motor and a cover and ejector connected by a gear connecting device separately installed in the turntable are interlocked with each other to place a record plate on a rotating plate. Or it relates to a record plate automatic insertion / extraction device of a turntable which can be taken out.

In general, the structure of a conventional turntable is to open the cover of the turntable, and to manually set the record plate on the rotating plate, to set the center hole of the record plate on the rotating shaft and to set it, and to change or remove the record plate manually. Therefore, it is cumbersome, such as opening the cover of the turntable and placing or removing the record plate on the rotating plate, and when the record plate center hole is not correctly inserted in the rotating shaft, it causes problems such as the board and the needle needle. Has been with me.

Therefore, the present invention is invented to solve the above problems as the cover is automatically opened while the record plate is separated from the rotating plate and inserted into the ejector to the outside, when combined, the record plate is placed on the ejector while the cover is set on the rotating plate It is an object of the present invention to provide a record plate automatic insertion / extraction device of a turntable that is to be closed.

In order to achieve the above object, the present invention establishes a drive shaft driven by a drive motor in the lower part of the turntable of the turntable, and corresponds to the cover and ejector drive pinions formed on both ends of the drive shaft so as to correspond to the vertical and horizontal racks and the cover driving rack. Are formed respectively, and the record plate is mounted or detached on the rotating plate via the supporting end of the ejector in accordance with the up, down and forward and backward movements of the ejector.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a plan view of a turntable according to the present invention, in which the upper body 1 has the same line with the ejector movement passage groove 4a and the cover 5 of the record plate 3 varying about the rotational axis 2. The cover drive rack movement grooves 4b of the driving shafts 6 are respectively formed, and as shown in FIGS. 2, 3, and 4, the driving shaft 6 is interposed across the rotation shaft 2 below the rotating plate 2a. Pinions 7a and 7b having different diameters are installed at the positions of the movement grooves 4a and 4b at both ends, while the transmission gear 8 installed to drive the drive shaft 6 is a built-in drive motor. The cover drive rack 5a is provided to be engaged with the drive gear 9a of 9) and the cover drive pinion 7a is formed to be perpendicular to both ends of the center of the cover 5. In addition, the ejector 10 having an upper end of the supporting end 10a protruding to the outside of the movable groove 4a and partially contacting the record plate 3 is a vertical rack 11a attached to the vertical end 10b. And the L-shape in which the horizontal rack 11b is formed on the horizontal end 11c of the lower end of the rack 11a, the racks 11a and 11b protruding from the respective ends 10b and 10c. It is carried out by the 12 and the spring 13.

On the other hand, a pair of guide members 14 are fixedly installed on the lower surface 1b of the main body to prevent left and right fluidity of the ejector 10 and to guide horizontal movement, thereby forming guide grooves 14a. It is equipped with a guide pin (14b) for controlling the horizontal movement distance of the ejector 10, between the guide groove (14a) and the guide pin (14b) on the guide groove (14a) when moving up and down the horizontal end (10c) An inclined surface 14c is formed to facilitate mounting.

According to the present invention having the above-described device, the transmission gear 8 drives the drive shaft 6 by the drive gear 9a of the drive motor 9 controlled by known switches (Eject, Loading S / W). Accordingly, the pinions 7a and 7b on the drive shaft 6 actuate the cover driving rack 5a and the vertical rack 11a of the ejector 10, so that the cover 5 is opened and the ejector 10 Is moved upward so that the support 10a lifts the record plate 3.

Therefore, since the vertical rack 11a is moved to the uppermost level when the rotating shaft 2 and the record plate 3 are completely separated, the ejector driving pinion 7b is smoothly leveled by the elastic force of the spring 13. The horizontal rack 11b is driven while being moved toward 11b so that the horizontal end 10c of the ejector 10 moves horizontally in the front direction through the guide groove 14a and is positioned at an appropriate distance. It is stopped by the guide pin 14b.

Therefore, after replacing or removing the conveyed record plate 3, the ejector 10 is moved in the rear direction while the rotation direction of the motor 9 is changed by a known switch selection, and the cover driving rack ( When the cover 5 starts to close by the operation of 5a) and the ejector driving pinion 7b slides with the vertical rack 11a, the ejector 10 starts to move downward again to record on the rotating plate 2a. As the plate 3 is placed, the cover 5 is completely closed.

In the present invention as described above, by simply pressing and selecting the function operation switch button formed on the front of the turntable is automatically inserted into the record plate to the outside, when the user only replaces or removes the record plate, the record plate is automatically placed on the rotating plate The cover is closed to reduce the manual operation required by the user, which improves the convenience of the product and prevents damage to the record plate or parts caused by incorrect settings.
