Locking and ejecting device of the multi-disc player of the present invention for achieving the above object is a magazine for receiving the tray with the disc is ejected by the tray takeout lever, and a first shaft fixed to the bottom surface of the loading plate for mounting the magazine Locking lever which is pivotally coupled to the center, eject lever which is pivotally coupled around the second axis fixed to the bottom surface of the loading plate on which the magazine is mounted, and the disk is withdrawn from the tray housed in the magazine. It consists of a loading gear for rotating the disk by a disk loading motor installed on the side wall of the main base for supporting the device, a vertical transfer lever and an eject lever for moving the disk up and down.

EXAMPLE

Hereinafter, a locking and ejecting apparatus of a multi-disc player of the present invention will be described in detail with reference to the drawings. For the same parts as the conventional description, the same reference numerals are used to avoid descriptive complications.

3 shows a locking and ejecting apparatus for a multi-disc player according to one embodiment of the present invention, where a is a sectional view, b is a sectional view at locking, and c is a sectional view at ejection.

As shown in FIG. 3, a plurality of trays are accommodated in the magazine 100, which is used to withdraw the disk D by the tray withdrawal lever 10c, and on the bottom of the magazine 100, two trays are provided. Locking grooves 10a and ejecting grooves 10b to be used for ejecting are formed, respectively. On the bottom of the first loading plate 50 to which the magazine 100 is mounted, a locking lever 20 which rotates about an axis 10a is provided, and two cylinders formed on the locking lever 20 are provided. The roller 20b protrudes through the studying 50a.

In addition, the eject lever 30 is rotatably coupled around the shaft 30a, and the roller 30b is formed on the upper surface of the first loading plate 50 through the through part 50b formed in the eject lever 30. It is formed to protrude, the locking lever 20 and the eject lever 30 is coupled to the spring 40 to exert a mutual tensile force.

On the other hand, on the side wall of the main base 200 is a disk loading motor 70 and the loading gear 80 is installed on the second loading plate 90, between the main base 200 and the second loading plate 90 Since the spring 16 is coalesced to apply a tensile force to the second loading plate 90, the spring 16 moves only to the right by the loading cam part 80a.

The main base 200 is provided with a recognition switch 11 which is operated by the magazine 100, and a loading switch 10 is attached to an end of the second loading plate 90 opposite to the second loading plate. The lower portion of the 90 is coupled to the vertical gear 12, the vertical feed lever 14 and the horizontal lever 15 inserted into the lead screw (13).

The operation of the locking and ejecting device of the multi-disc player of the present invention having such a configuration will be described. Referring to FIG. 3, when the magazine 100 is inserted when one end of the locking lever 20 and one end of the eject lever 30 are in contact with each other to maintain the original state, the magazine 100 is ejected. The groove 10b pushes the roller 30b to rotate the eject lever 30 in one direction. In this case, the locking lever 20 is released from the contact state of the eject lever 30, and the locking lever 20 rotates counterclockwise so that the rollers 20b are formed in the locking grooves 10a of the magazine 100, respectively. It is inserted locked to maintain the locked state. This state is 3b.

Subsequently, during ejection, when the horizontal lever 15 moves in one direction, one end of the locking lever 20 is pulled clockwise and the locking lever 20 is rotated about the shaft 20a to rotate the magazine 100. When each of the rollers 20b escapes from the locking groove 10a of the < RTI ID = 0.0 >), the ejector lever 30 is pushed by the roller 30b by the elastic force of the tensioned spring 40 pushes the ejector groove 10b. ) Rotates clockwise, the magazine 100 is ejected.

At this time, ejection and locking are performed in a state in which the first loading plate 50 is always closed (FIG. 3C).

5 is a flowchart sequentially showing the operation process by the apparatus of the present invention.

The operation of the locking and ejecting device of the multi-disc player of the present invention having the above configuration will be described in detail with reference to the flowchart.

When the magazine 100 is inserted into the first loading plate 50 shown in FIG. 2 as shown in step S1 of FIG. 5, the magazine recognition switch 11 is operated as an operation of detecting that the magazine 100 is normally mounted. (Step S2), and if it is activated, operating the first loading plate transfer motor to open the magazine 100 in the open direction (step S3), and then the loading plate check switch is operated. When the check switch is operated in step S4 and the step S4, the motor stops the loading plate horizontal transfer motor and vertically operates the vertical transfer motor for driving the vertical transfer power transmission gear 12. Transferring the conveying lever 14 to the upward direction (step S5), and as a result of determining whether or not the desired position of the selector of the disc D is desired (step S6), and stopping the operation of the vertical conveying motor, Disc Operating the ding motor 70 (step S7), determining whether the loading switch 10 has been operated (step S8), and if the loading switch 10 has been operated in the step S8, the disc loading motor 70 ), The vertical feed motor 14 is lowered by operating the vertical feed motor in the reverse direction (step S9), the step of determining whether it is the initial position (step S10), and the vertical feed if the initial position Stopping the operation of the motor to stop the vertical transfer lever 14 from descending, and operating the motor for the horizontal transfer to move the first loading plate 50 in the cloth direction (→), and to complete the cloth. A step of determining whether the recognition switch is activated (step S12), and if it is completed, stops the operation of the horizontal feed motor and operates the spindle motor and the pickup spindle motor to perform the regeneration mode (step S13).

When the ejector is input while the play mode is performed as described above, the vertical transfer lever 14 and the horizontal lever 15 are raised to the eject position, and then the disc loading motor 70 is operated to operate the second plate 90. By rotating the movable loading gear 80, the horizontal lever 15 is operated by turning the locking lever 20 in the clockwise direction and ejected back to the initial state.

4A and 4B are plan views of an apparatus according to another embodiment of the present invention. In the magazine 100 of the apparatus shown in FIG. 4, two lever entry escape grooves 10d, two locking grooves 10a, and an ejection groove 10b are formed, and the two lever entry escape grooves ( The magazine selector lever portion 15b and the eject lever ejection lever portion 15a of the horizontal lever 15 are inserted into the ejector lever portion 15a, and the eject lever 30 and the spring 40 are inserted into the ejector lever portion 15a. The free end of the locking lever 2 is coupled.

As described above, according to the locking and ejecting apparatus of the multi-disc player of the present invention, since ejecting and locking are realized at the same time, the product configuration can be simplified, and the effect of miniaturization is reduced.
