Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a loading device used when loading a card-type compact disc (CD) into a slot-in type recording / reproducing apparatus.

[0002]

2. Description of the Related Art CD-ROMs have become widespread as recording media from which information relating to computers, music, games and the like can be read out. It is necessary to distribute the centrifugal force uniformly, and the conventional CD-ROM
The shape was a circular shape having a standard size of 120 mm in diameter and a single size of 80 mm in diameter.

On the other hand, a card-type CD-ROM having a card size fixed to ordinary life has recently appeared on the market, and is expected to be widely used as business cards, sales software, electronic merchandise catalogs and the like. You.

[0004]

On the other hand, there are known a CD-ROM player of a tray type and a slot-in type, all of which are standard size and single size circular CD-ROM players. Therefore, even if a card-type CD-ROM is directly loaded into the CD-ROM player, the CD-ROM player cannot be rotated smoothly to read data stably.

On the other hand, a card type CD-ROM has a single-size CD-ROM formed on a tray of a tray-type CD-ROM player on its data storage surface.
To form an arc-shaped guide step that fits into the guide groove for
This follows the guide groove for a single size CD-ROM, thereby suppressing centrifugal force, allowing the CD to rotate smoothly, and to allow stable reading of data.

However, one slot-in type CD
-A method of rotating a card-type CD-ROM smoothly for a ROM player and reading data stably has not yet been found.

SUMMARY OF THE INVENTION It is an object of the present invention to smoothly rotate a card-type CD in a slot-in type CD-ROM player or the like and to perform stable data reading.

[0008]

SUMMARY OF THE INVENTION In view of the above circumstances, the present invention has an outer shape which is loaded into a drive section of a slot-in type recording / reproducing apparatus, and engages four corners of a card-type compact disc inside. The present invention proposes a card-type compact disc loading tool in a slot-in type recording / reproducing apparatus having a cylindrical guide step formed.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS In a loading device according to the present invention, a recording portion is inserted into a peripheral portion of a center hole, and a card-type CD is inserted into a cylindrical guide step at four corners of the card. After being loaded into the drive unit through the mouth, recording on the recording unit or reproduction of data from the recording unit is performed by a conventionally known method.

For example, when the loading device containing the card type CD as described above is loaded into the drive unit from the insertion opening of the CD recording or reproducing apparatus, the table rises, the rotating shaft fits into the center hole, and the card type CD is inserted. By rotating the CD, recording on the recording unit or reproduction of data from the recording unit is performed.

In this case, in the present invention, since the four corners of the card type CD are engaged with the cylindrical guide step, the card type CD rotates smoothly along the cylindrical guide step, and thus a stable recording section Recording or reproduction of the data in the recording unit.

In a card type CD having an arcuate guide step formed therein, a cylindrical guide step which engages the arcuate guide step may be formed in the loading device.

[0013] In this case, since the arc-shaped guide step of the card type CD is fitted into the cylindrical guide step formed inside the loading device, the card type CD smoothly moves along the cylindrical guide step. It is possible to rotate, and thus perform stable recording on the recording unit or reproduction of data from the recording unit.

In this case, if a cylindrical guide step which engages the four corners of the card type CD with the outer periphery of the cylindrical guide step is formed, the card type CD becomes a double cylindrical guide step. Can be rotated along, so that smoother rotation is guaranteed.

[0015]

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a block diagram showing an embodiment of the present invention; FIG. 2 is a block diagram showing an embodiment of the present invention; FIG. The loading device 1 has a cylindrical shape whose outer periphery 1a is loaded into a drive section of a CD-ROM player.

A card type CD-ROM is provided in the loading device 1.
A cylindrical guide step 3 is formed which engages the four corners 2a, 2b, 2c, 2d, and a reading window 4 is formed in the guide step.

On the other hand, a recording section 5 is formed on one surface of the card type CD-ROM 2, and a center hole 6 is formed in the center of the recording section 5.

The card type CD-ROM 2 is stored in the loading device 1 with the recording section 5 facing the reading window 4 and the four corners 2a, 2b, 2c, 2d engaged with the cylindrical guide step 3.

The loading device 1 containing the card type CD-ROM 2 is loaded into the drive unit 8 in the CD-ROM player from the insertion slot 7.

When the loading device 1 is loaded into the drive unit 8,
As is well known, for example, the table is raised, the rotating shaft 9 is fitted into the center hole 6, and the card type CD-ROM 2 is rotated, so that the data in the recording unit 5 is reproduced.

In this case, the four corners of the card type CD-ROM 2
Since 2a, 2b, 2c, and 2d are engaged with the cylindrical guide step 3, the card type CD-ROM 2 rotates smoothly along the cylindrical guide step 3, and therefore, stable recording on the recording unit In addition, data in the recording unit can be reproduced.

FIG. 3 and FIG. 4 show an arc-shaped guide step inside thereof.
This shows another embodiment of the present invention in the case of using a card type CD-ROM 2 formed with a cylindrical guide 10. In this embodiment, a cylindrical guide for engaging an arcuate guide step 10 inside the loading tool 1 is shown. A step 11 is formed.

In this case, since the arc-shaped guide step 10 of the card type CD-ROM 2 is fitted into the cylindrical guide step 11 formed inside the loading device 1, the card type CD-RO is provided.
M2 rotates smoothly along the cylindrical guide step 11, so that stable recording to the recording unit or reproduction of data from the recording unit can be performed.

FIGS. 5 and 6 show an arc-shaped guide step inside thereof.
This shows still another embodiment of the present invention in the case of using a card type CD-ROM 2 in which a card type CD-Rom 10 is formed. In this embodiment, a card type CD-R
A cylindrical guide step 3 for engaging the four corners 2a, 2b, 2c, 2d of the OM 2 is formed.

In this case, since the card type CD-ROM 2 can be rotated along the double cylindrical guide steps 11, 3, smoother rotation is guaranteed.

[0026]

In summary, according to the present invention, even in a slot-in type CD recording / reproducing apparatus, a card type CD is smoothly rotated to perform stable recording on a CD or reproduction of data recorded on the CD. Can be made.
