Description

Chucking / Unchucking maintenance structure of optical disc player

The present invention relates to a chucking / unchucking holding structure of an optical disc player, and more particularly, a driving force transmitted from a front-rear driving device of a tray for loading an optical disc selected from at least one or more optical discs accommodated in an optical disc player on a turntable. A chucking / unchucking holding structure of an optical disc player capable of maintaining a chucked / unchucked state of a slider cam to be chucked by the present invention.

In general, an optical disc player records a digital signal in a concave-convex shape on a disc, and then projects a light having high condensing power such as a laser beam onto the surface of the disc, and then receives the reflected light to reproduce the recorded signal according to the difference in the amount of light. It is an electronic device.

The disc changer includes a disc changer for taking out and recording / reproducing selected discs from a magazine accommodating a plurality of discs coaxially, and rotating the roulette by a driving apparatus from a roulette for accommodating at least one disc in the same plane. There is a disc changer that records / plays back the selected disc.

As described above, in a disc changer in which a roulette for accommodating at least one optical disc on the same plane is rotatably mounted in a forward and reverse direction with respect to the tray by a drive device thereof, the tray is loaded / unloaded in the front-rear direction. Since the chucking device is mounted on the main deck on which the drive is mounted, the chucking device is mounted on the turntable to chuck the selected optical disk among the at least one optical disc accommodated in the tray, and the drive is driven to drive the tray mounted on the main deck. The manufacturing cost increases due to the increase in the number of parts constituting the chucking device for chucking, and the structure of the optical disc player is complicated because a separate locking member is required to maintain the chucking state of the optical disc on the turntable by driving the chucking device. This may cause breakdowns and malfunctions during operation. It has a problem that occurs frequently.

Accordingly, an object of the present invention is that it is unnecessary to install a separate member for maintaining the chucking / unchucking state of the slider cam which drives the optical disc accommodated in the tray of the optical disc player by the drive of the tray and seats on the turntable for chucking. It is to provide the chucking / unchucking maintenance structure of the optical disc player, which reduces the number of costs and lowers the cost, and the operation of the optical disc player is simplified, thereby preventing failure and malfunction during operation.

The object of the present invention described above is to chuck / remove an optical disc on a turntable by driving it by a tray in which a roulette for accommodating at least one optical disc is rotatably mounted in a reverse direction and a drive device for loading / unloading the tray. A chucking / unchucking holding structure of an optical disc player having a main deck on which an unchucking slider cam is mounted and a sub deck on which the turntable and optical pickup are mounted, the chucking / unchucking state is formed on one side of the slider cam. Indentation and the main deck is formed integrally as an initial state for pressing the slider cam side, and the slider cam is driven in the chucking / unchucking state of the slider cam is selectively seated in the groove to support it Chucking / chucking of an optical disc player, characterized in that it comprises a tension member for holding The holding structure is achieved by providing.

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

1 is a plan view of main parts of an unchucking state of an optical disc player according to the present invention, and FIG. 2 is a plan view of main parts of a chucking operation of an optical disc player according to the present invention, and FIG. Top view.

As shown in the figure, a drive motor 11 capable of forward and reverse rotation is mounted on one side of the top surface of the main deck 10 of the optical disc player in which a tray for accommodating at least one optical disc is loaded, and the drive motor 11 The first gear 14 is formed on the coaxial of the pulley 13 is connected to the belt 12, the coaxial of the second gear 15 is meshed with the first gear 14 A third gear 16 is formed, and a boss 17A is formed on one side of the upper surface of the cam gear 17 engaged with the third gear 16.

Slider cam 18 for chucking the optical disc loaded from the tray on the turntable at a predetermined position on the main deck 10 is slidably movable in the left and right directions, and the boss of the cam gear 17 is located at one side of the slider cam 18. 17A) is coupled to the guide portion 19 is formed to receive the rotational movement of the drive motor 11 in a linear motion, grooves for indicating the chucking / unchucking state of the slider cam 18 on the side of the slider cam (18) 18A and 18B are formed, and as the slider cam 18 is driven to selectively engage the grooves 18A and 18B to pressurize and support the slider cam 18, the chucking / unchucking of the slider cam 18 is performed. The tension member 20 for providing stability to the test operation is integrally formed as an initial state for pressing the side surface of the slider cam 18 to the main deck 10.

Reference numeral 21 is a chuck that tightly presses the optical disk by magnetic force during chucking.

Referring to the operation of the present invention configured as described above, as shown in Figure 1, the driving force of the drive motor 11 mounted on the main deck 10, its rotational force counterclockwise pulley 13 through the belt 12 Direction, the second gear 15, which is engaged with the first gear 14 formed coaxially of the pulley 13 is rotated in the clockwise direction, and the coaxial of the second gear 15 The cam gear 17 engaged with the formed third gear 16 is rotated counterclockwise.

Accordingly, the slider cam 18 is inserted into the groove 19A of the guide portion 19 of the slider cam 18 by the boss 17A formed on one side of the upper surface of the cam gear 17 by the rotation of the cam gear 17. The movement starts to the left on this drawing.

At this time, the protrusion 20A of the tension member 20 formed integrally with the main deck 10 is separated from the groove 18A formed on the side of the slider cam 18.

And, as shown in Figure 2, when the cam gear 17 is to rotate in the same direction a little more, the boss 17A of the cam gear 17 and the guide portion 19 of the slider cam 18 The slider cam 18 is moved to the left side by the coupling of the groove 19A, and the protrusion 20A of the tension member 20 formed integrally with the main deck 10 tensions the side surface of the slider cam 18. Since it is pressed by the elastic force of the member 20, it is possible to impart stability to the chucked operation of the optical disk.

As shown in FIG. 3, the slider cam 18 is completely moved to the left side due to the continuous rotation of the cam gear 17. As a result, a tension member integrally formed on the main deck 10 ( 20A of the protrusion 20 is formed on the side of the slider cam 18 so as to be seated in the groove 18B indicating the chucking state and to support it, thereby maintaining the chucking state. This completes the chucking operation of the optical disc.

As described above, the chucking / unchucking holding structure of the optical disc player according to the present invention maintains the chucking / unchucking state of the slider cam for chucking the optical disc by a driving force for loading a tray containing at least one optical disc. There is no need to install a separate member to reduce the manufacturing cost by reducing the number of parts, and the structure is simplified by the structure of the optical disc player to operate smoothly to prevent the failure and malfunction during operation to increase the reliability of the product.
