Abstract

PURPOSE: A loading device of a disk player is provided to fix a cartridge holder to an upper part of a bracket, and to load/unload a disk to a turn table. Therefore, it is possible to reduce a moving distance/time for loading/unloading of the cartridge holder. Also, the disk player can be miniaturized. CONSTITUTION: A disk cartridge(11) is loaded to a cartridge holder(12). The cartridge holder is fixed to the both upper sides of a bracket(10). A disk is installed in a turn table(15). The turn table(15), a spindle motor(14) and an optical pick-up are installed in a main base. The main base is movably installed in the both lower sides of the bracket(10) in order to be moved up/down by an elevator. The main base is ascended by the elevator to install the disk in the turn table at a state that the disk cartridge(11) is inserted into the cartridge holder(12).

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a disc player loading apparatus, and more particularly to a disc player in which a holder for accommodating a disc cartridge is fixedly installed, and a disc is loaded (settled) and unloaded on a turntable while the main base having a turntable or the like is elevated. It relates to a loading device of.

In the conventional disc player loading apparatus, as shown in FIGS. 1 and 2, the cartridge holder 2 in which the disc cartridge 1 is accommodated is directly lowered in a state in which the disc holder 1 is horizontally moved upwardly of the spindle motor 3. The disk 1a, which is lowered into the room and accommodated in the disk cartridge 1, is loaded (mounted) on the turntable 4 of the spindle motor 3.

However, in the conventional disc player loading apparatus as described above, the disc 1a is loaded (mounted) and unloaded onto the turntable 4 of the spindle motor 3 while the cartridge holder 2 is moved horizontally and vertically. Since the cartridge holder has a large amount of movement of the cartridge holder, a lot of time is required for loading and unloading, and since the space required for the movement of the cartridge holder must be secured inside the player, there is a problem in that the player is difficult to be molded.

The present invention has been made in view of the above-described problems, and provides a loading device for a disc player that can shorten the moving distance and the moving time for loading and unloading a cartridge holder, and can miniaturize the player. There is this.

In order to achieve the above object, the present invention, the cartridge holder for receiving the disc cartridge is fixedly installed on both sides of the bracket; A main base provided with a turntable, a spindle motor, an optical pickup, etc., on which disks are seated, is installed to move up and down by lifting means; The main base is lifted by the elevating means in a state where the disc cartridge is completely inserted into the cartridge holder, so that the disc is seated on the turntable.

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

As shown in FIGS. 3 to 5, the disc player loading device according to the present invention includes a cartridge holder in which the disc cartridge 11 is accommodated on both sides of the bracket 10 having a cross-sectional shape of the letter “C” ( 12 is fixedly installed, the lower side of both sides of the bracket 10, the turntable (15) on which the disk (11a) accommodated in the disc cartridge 11 is seated (loaded) and the spindle motor for rotating the turntable (15) ( 14) and the main base 13 provided with the optical pickup 16 and the like are installed to move up and down by the elevating means 20.

The lifting means 20 is installed between the lower side of both sides of the bracket 10 and the main base 13, the rack 22 is formed on one side and a pair of inclined long holes 23 on each side with a predetermined distance, respectively The loader 21 is formed, a pair of vertical long holes 24 formed at predetermined distances on both sides of the lower side of the bracket 10, respectively, and are installed at predetermined distances on both sides of the main base 13, respectively. A pair of guide pins 25 slidably coupled in a state of penetrating the 23 and the vertical long hole 24, a gear 26 engaged with the rack 22, and the gear 26 to rotate It is comprised with the motor 27.

The loading device of the disc player according to the present invention configured as described above operates as follows.

First, the disc cartridge 11 is forcibly inserted into the cartridge holder 12 so that the disc 11a housed in the disc cartridge 11 is installed in the main base 13 as shown in FIGS. 3 and 4. It is located above the turntable 15. At this time, the disc cartridge is locked in the locked state by the locker 17.

When the disk 11a of the disk cartridge 11 is located directly above the turntable 15, the main base 13 is lifted by the elevating means 20, and the disk is turned on the turntable 15 installed in the main base 13. The disk 11a housed in the cartridge 11 is seated (loaded).

Herein, the operation of the lifting means 20 will be described in more detail. That is, as the motor 27 as the elevating means 20 is driven to rotate the gear 26, the loader 21 having the rack 22 engaged with the gear 26 is moved in the direction of the arrow “A”. Done. Accordingly, the main base 13 slidably coupled in a state of penetrating through a pair of inclined long holes 23 formed on both sides of the loader 21 and a pair of vertical long holes 24 formed on both sides of the bracket 10, respectively. As the main base 13 rises along the vertical long hole 24 formed in the bracket 10 by the guide pin 25 of the main base 13, the turntable 15 installed on the main base 13 is raised. The disk 11a housed in the disk cartridge 11 is seated as shown in Figs. 5 and 6, thereby completing the loading operation.

At the time of unloading, the motor 27 is driven in the reverse direction to move the loader 21 in the direction opposite to the arrow “A” direction. Accordingly, as the loader 21 moves in the opposite direction to the arrow, the inclined hole 23 of the loader 21 pushes the guide pin 25 of the main base 13 so that the main base 13 is perpendicular to the bracket 10. While descending along the long hole 24, the turntable 15 is separated from the disk 11a and returned to the position before loading, and at the same time the locking state of the disk cartridge 11 is released by a conventional ejection means (not shown). The disc cartridge 11 is taken out from the cartridge holder 12 by a predetermined length.

According to the loading device of the disc player of the present invention as described above, the cartridge holder is fixed to the upper portion of the bracket, the main base is to be loaded or unloaded to the turntable while the main base is raised or lowered by the lifting means, As the cartridge holder is moved horizontally and vertically, the moving distance and the moving time for loading and unloading of the cartridge holder can be shortened as compared with the method of loading or unloading the disk onto the turntable, and the cartridge holder is fixedly installed. Since the space required for horizontal movement of the conventional cartridge holder does not need to be secured inside the player, the player can be miniaturized.
