Description

Optical Disc Changer for Car Optical Disc Player

The present invention relates to an optical disc changer usable in an optical disc player for a vehicle, and more particularly, to an optical disc changer that can be selectively used in an optical disc player mounted on a vehicle.

In general, an optical disc player such as a laser disc player (LDP) or a compact disc player (CDP) mounted on a vehicle may load a recording / reproducing disc from the outside onto a turntable by a loading mechanism to clamp the clamping unit. unit, and then reproduces the information recorded on the disc by an optical pick-up unit moving in the radial direction while rotating the disc.

Fig. 1 schematically shows the side of such a vehicle optical disc player. The disc insertion hole 14 into which the optical disc 12 is inserted is formed in the upper portion of the front surface of the optical disc player main body 10, and the control panel in which the control panel 20 is inserted is mounted on the front of the disc insertion hole 12. The member 16 is stuck. In the control panel mounting member 16 and the control panel 20, holes 18 and 22 corresponding to the disc insertion holes 12 are formed, respectively. The control panel 20 is detachable from the control panel mounting member 16 for the purpose of preventing theft.

However, such a conventional optical disc player for a vehicle is mounted around the instrument panel inside the vehicle, and since one optical disc is usually used, it is inconvenient to replace these discs when a driver wants to reproduce another optical disc. In order to solve this problem, a separate optical disc changer that can use a plurality of optical discs is mounted on a vehicle.

However, such an optical disk changer is generally installed in the trunk part in consideration of space constraints inside the vehicle, thereby reducing the storage space of the trunk, and also has a problem in that the installation is cumbersome and the installation cost occurs. In addition, there is a problem that the efficiency is lowered because they are used separately from each other regardless of the optical disk player.

The present invention has been made in view of the above-described conventional problems, and an object thereof is to provide an optical disk changer which can be easily used by being selectively mounted in a vehicle optical disk player.

In order to achieve the above object, the optical disk changer according to the present invention has a shape that can be inserted into and detached from the control panel mounting member fixed to the front surface of the optical disk player body, and has an insertion portion having a hole corresponding to the disk insertion hole of the optical disk player body. A formed casing, a magazine installed inside the casing to supply the disk to the optical disc player body through the opening of the casing, a magazine shandong means for moving the magazine up and down along the guide rails installed before and after the casing, and the disk; And disk loading / unloading means for loading and unloading the transferred disk into the optical disk player main body.

According to one preferred feature of the present invention, the casing can be inserted into and detached from the optical disc player body, and the magazine containing the plurality of optical discs in the casing is moved up and down by magazine up and down conveying means, and the optical disc desired to be used is stored. When the magazine is moved to the desired position, the desired optical disc is transferred to the disc transfer means, and then the disc loading / unloading means are driven to smoothly load and unload the disc to the vehicle optical disc player.

As described above, the present invention can be selectively used in a vehicle optical disc player and is easy to mount, and thus has an effect particularly suitable for efficient use of the optical disc player and the optical disc changer.

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

2 to 4, the disc changer according to the present invention is composed of a casing 30 having an inserting portion 32 formed on the front surface, and the inserting portion 32 is fixed to the front surface of the optical disc player main body 10. The control panel mounting member 20 is detachable and has a hole 34 corresponding to the disc insertion hole 12 of the optical disc player main body 10.

Inside the casing 30, the magazine 40 which is moved up and down along the guide rail 50 installed before and after is installed.

The magazine 40 has a rack 42 attached to its side, a first gear 62 engaged with the rack 42, a vertical drive motor 64, and a shaft 66 of the vertical drive motor 64. It is moved up and down by a magazine moving means 60 composed of a pinion gear 68 formed in the second gear 69 and a second gear 69 engaged between the pinion gear 68 and the first gear 62.

When the magazine 40 is moved to the position where the desired disk is accommodated by the shandong means 60, the disc tray lever 73 and the cam gear 75 rotatably mounted at the center of the lever 73 are opened. The disk conveying means 70 provided operates the drive motor 76 to convey the disk 12 to the optical disk player 10. That is, the pinion gear 78 is formed in the shaft 77 of the drive motor 76, the gear 79 is engaged between the pinion gear 78 and the cam gear 75, the disk tray lever 73 At one end thereof, as shown in FIG. 3, a locking portion 71 that is caught by the locking projection 46 of the disk transfer lever 44 of the magazine 40 positioned at the disc insertion position is formed, and is perpendicular to the center. The guide groove 72 is formed to be long and movable left and right, and the cam gear 75 is rotatably fixed to the center of the disc tray lever 73, and the rotation regulating pin 74 protruding from the rear surface thereof has a disc tray. It moves along the upper and lower guide grooves 72 of the lever 73. At this time, the conveying length of the disk 12 conveyed by the disk conveying means 70 is conveyed by the length of the upper and lower guide grooves 72.

The conveyed disk 12 has a loading / unloading motor 81, a pinion gear 83 formed on the shaft 82 of the loading / unloading motor 81, and one end formed to fit the pinion gear 83. Rolling bracket having a biting gear 84, a central shaft fixing gear 85 meshing with the gear 84, and a rolling gear 86 formed at the other end to mesh with the shaft fixing gear 85 therein. Loaded and unloaded into the optical disc player main body 10 by a disc loading / unloading means 80 consisting of 88.

The operation of the disc changer according to the present invention configured as described above will be described with reference to FIGS. 2 and 4.

In FIG. 2, when the disc stored in the upper fourth tray of the magazine 40 is to be reproduced, the vertical drive motor 64 is driven to adjust the position of the magazine 40. Subsequently, when the drive motor 76 is driven, the cam gear 75 rotates counterclockwise as shown by an arrow, and the rotation control pin 74 moves the upper and lower guide grooves of the disc tray lever 73. 72, the disc tray lever 73 moves to the position as shown in FIG. At the same time, since the engaging projection 46 of the disc transfer lever 44 of the magazine 40 is caught by the engaging portion 71 formed at one end of the disc tray lever 73, the desired disc 12 is an optical disc player. It moves toward 10 by the length of the upper and lower guide grooves 72 of the disc tray lever 73. Then, the disc loading / unloading motor 80 is operated to rotate the gears 84, 85, 86 in the rolling bracket 88 to load the disc 12 into the optical disc player 10.

On the other hand, unloading of the disc 12 from the optical disc player 10 proceeds in the reverse order of the above-described loading.

As described above, according to the present invention, since the optical disc changer can be easily and selectively used in a vehicle optical disc player, there is an effect particularly suitable for the efficient use of the optical disc player and the optical disc changer.
