Abstract

PURPOSE:To shorten the time required for exchange of optical disk media by taking out an optical disk medium loaded presently when another next optical disk medium is loaded through a slot. CONSTITUTION:When an optical medium 5l is exchanged, the medium lift arms 23 and 24 are actuated toward arrow heads A and B respectively. Then the medium 5l is pushed up toward an arrow head C and stopped at the position of a medium discharging port 22. Then the cartridge of the medium 5l and a cartridge storing an optical medium 5m are moved toward an arrow head D and sent out through a medium exchange part 3. Then both cartridge are put into a medium reading/writing part 2 and the media 5l is stored into the cartridge and 5m is loaded into the part 2. Thus the time required for exchange of both media 5l and 5m can be shortened.

Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field The present invention relates to an optical disc device, and more particularly to an optical disc device used as a storage device for a computer or the like.

BACKGROUND OF THE INVENTION Conventionally, optical disk media have been automatically exchanged in optical disk devices, particularly in collective type optical disk devices.

The conventional optical disc device will be explained using FIG. 2. The figure is a schematic diagram showing the configuration of a conventional optical disc. In the figure, the conventional optical disk device is configured to include a control section 1, a medium read/write section 2, a medium exchange section 3, and a medium storage cell 4.

The medium storage cell 4 stores a plurality of cartridges each storing an optical disk medium 5.

The medium exchange section 3 has an arm for inserting and removing cartridges into and from the medium storage cell 4 and the medium reading/writing section 2.

The medium reading/writing section 2 has a head for reading and writing data therein.

The control section 1 controls each section of the apparatus.

An automatic exchange system for optical disc media in a conventional optical disc device having such a configuration will be described.

First, the medium exchange section 3 takes out the cartridge of the optical disk medium currently loaded in the medium read/write section 2 and the car 1 to the cartridge storing the optical disk medium to be loaded next from the medium storage cell 4. It moves in the direction of arrow H and stops at the position shown in the figure.

Thereafter, a cartridge (not shown) is inserted into the medium read/write section 2, and the currently loaded optical disk medium is taken out and stored in the car 1 heritage. After inserting the cartridge of the optical disk medium to be loaded next into the medium read/write section 2, the medium exchange section 3 loads the optical disk medium, moves in the direction of arrow J, and moves to the cartridge in which the previously taken out optical disk medium is stored. 1 to the cartridge were returned to the medium storage cell 4.

However, in this case, the replacement method is such that the optical disc medium loaded in the medium read/write section 2 is removed and then the next optical disc medium is loaded, so there is a drawback that it takes time to replace the optical disc medium.

OBJECTS OF THE INVENTION An object of the present invention is to provide an optical tisf device that can shorten the time required to replace optical disk media.

Composition of the Invention The optical disk device of the present invention has a medium insertion port for inserting two optical disk media and a medium ejection port for taking out the optical disk medium, and a medium reading/writing means for reading and writing predetermined information from and to the optical disk medium; It is characterized by comprising a medium exchange means for taking out the optical disk medium from the medium ejection port when the optical disk medium is inserted into the medium insertion port.

Example Hereinafter, the present invention will be explained in detail using the drawings.

FIG. 1 is a schematic diagram of a medium reading/writing section 2 and a medium exchange section 3 of an embodiment of an optical disk device according to the present invention. In the figure, a medium reading/writing section 2 of an optical disk device according to an embodiment of the present invention includes a medium insertion port 21 for inserting an optical disk medium, a medium ejection port 22 for ejecting an optical disk medium, and a medium ejection port 22 for lifting the medium. It is configured to include medium lifting arms 23 and 24. In addition, 511! is an optical disc medium.

The medium reading/writing section 2 having such a configuration has a medium insertion slot 2.
The optical disk medium is taken out from the carriage of car 1 (not shown) inserted from car 1, and after reading and writing data, it is lifted by medium lifting arms 23 and 24, stored in car 1 - carriage (not shown), and taken out from the medium ejection port. 22. The insertion and removal operations will be explained using FIGS. 3 and 4.

FIG. 3 is a schematic diagram showing the loading position of the optical disk medium during read/write operations of the medium read/write section 2. As shown in FIG.

Moreover, FIG. 4 is a schematic diagram showing the operation of inserting and ejecting an optical disk medium.

First, a data read/write operation is performed on the optical disk medium 5ρ at the position shown in FIG.

When replacing the optical disk medium 5ρ according to instructions from the control unit 1, the medium lifting arm 2 is moved by a spring (not shown) or the like.
3 and 24 operate in the direction of arrows A and B. Then,
The optical disk medium 5ρ is pushed up in the direction of arrow C and stops at the position of the medium ejection port 22 (the position shown in FIG. 1).

At this time, the medium exchange section 3 takes out the cartridge of the optical disk medium 5ρ and the carmy ridge in which the optical disk medium 5m to be inserted next is stored from the medium storage cell 4.

Then, as shown in FIG. 4, under the control of the control section 1, the cartridge containing the optical disk medium 5ρ and the cartridge storing the optical disk medium 5m are moved in the direction of the arrow and sent out from the medium exchange section 3, and are sent out from the medium reading/writing section. 2 is inserted. Then, the optical disk medium 5ρ is stored in the cartridge, and the optical disk medium 5m is loaded into the medium reading/writing section 2.

In this case, media lifting arms 23 and 24 are pushed down in the direction of arrows E and F. As a result, the medium lifting arms 23 and 24 stop at the positions shown in FIG. 3, and data is read and written to the optical disk medium 5m.

On the other hand, the cars 1 to ridge storing the optical disk medium 5ρ and the cartridge for the optical disk medium 5m move in the direction of arrow G and are stored in the medium exchange section 3, and then stored in the original medium storage cell 4. It will be done.

In other words, the present invention is controlled so that when the next optical disc medium to be loaded is inserted from the insertion slot, the currently loaded optical disc medium is taken out from the slot.

DETAILED DESCRIPTION OF THE INVENTION As described above, the present invention reduces the time required to replace optical disk media by removing the currently loaded optical disk medium when inserting the next optical disk medium to be loaded from the insertion slot. It has the effect of being able to
