Recognition Hall Converter of Cartridge Adapter for Disk Storage

The present invention relates to a recognition hole converting apparatus for a disc housing cartridge adapter, and more particularly, to a disc accommodating disc for converting a recognition hole according to a state of a 12 cm disc directly contained in a cartridge adapter or a disc accommodated in a small cartridge. It relates to a recognition hole converter of the cartridge adapter.

In general, a cartridge is for preventing dust, fingerprints, scratches, etc. on the surface of Table 1 of different sized discs stored therein to record desired information without errors and to protect the recorded information.

Such a 12cm cartridge is composed of a cartridge case in which a synthetic resin or the like is formed in a predetermined size (137.5x124.5 mm) so as to accommodate a disk, a shutter mounted on the front side thereof, and a cover hinged to the cartridge case rear side.

Upper and lower surfaces of the cartridge case are provided with a receiving hole having a diameter of 34 mm and an opening hole communicating therewith. The accommodation hole allows the turntable (? 28 to 30 mm) and the chucking clamper of the recording and reproducing apparatus to enter, and the opening hole serves as a transfer path of the optical pickup apparatus.

The cartridge case is provided with a pair of positioning pin holes and a plurality of recognition holes which are positioned diagonally to check the state of the 12cm disc.

Through holes are formed in the cover at positions corresponding to the recognition holes, respectively. These through holes are for allowing the recognition terminals attached to the deck base to be inserted into the recognition holes.

Here, the recognition terminals are for recognizing whether the disc is exchanged with respect to the cartridge case, whether the disc is to be written or erased, and the recording surface of the disc, i.e., single or double side, and the state (track, sector, etc.) of the stored disc.

In the conventional 12cm disc storage cartridge configured as described above, when the cartridge containing the disc is seated on a seating member such as a tray and then inserted into the recording / playback apparatus, the shutter mounted on the cartridge case is the shutter opening / closing means of the recording / playback apparatus. It is moved by to open the receiving hole and the opening hole.

At this time, as the deck base is raised by a predetermined angle, the turntable and the chucking clamper enter the receiving hole to seat and chuck the disc, and at the same time, the positioning pin is inserted into the positioning pin hole to determine the position of the cartridge case with respect to the recording / playback apparatus. A plurality of recognition terminals are respectively inserted into the recognition holes and through holes formed in the cover so as to recognize the state of the disc.

Thereafter, the optical pickup apparatus records and / or reproduces information on the disc while being transported along the opening hole.

On the other hand, a small cartridge containing a disc of 8 cm in diameter is manufactured to have a size of 95x90 mm, and a small cartridge is formed with a receiving hole of 25 mm in diameter, so that the disk is directly seated on the turntable of the recording / reproducing apparatus.

And, as described above, the front side of the cartridge is equipped with a shutter for closing the receiving hole and the opening hole, the rear surface thereof is formed with a plurality of recognition holes so that the recognition terminals for recognizing the state of the disk is inserted.

When the small cartridge containing the 8 cm disc is inserted into the recording and reproducing apparatus, the shutter is moved in one direction as both sides of the cartridge are inserted into the shutter opening and closing member, thereby simultaneously opening the receiving and opening holes. The turntable enters inside.

Then, as described above, the disc recognizes the state of the disc accommodated in the small cartridge by inserting a plurality of recognition terminals into the recognition holes and the through holes, respectively.

In other words, the recognition terminal is inserted into the recognition hole of the small cartridge in which the 12 cm disc or 8 cm disc housed directly in the cartridge adapter is inserted, thereby recognizing the disc ejected state for the disc or cartridge that was originally shipped, and the recording surface of the disc Recognize one or both sides, and recognize the state of the disc when it is replaced in the cartridge.

However, in the cartridges for storing 12 cm or 8 cm discs as described above, the cartridges for storing 12 cm and 8 cm discs are manufactured in a size appropriate for the diameter of the disc. When the cartridge is inserted, it is impossible to insert the positioning pin and flow occurs in the front and rear and / or left and right directions, and in particular, there is a problem in that the receiving hole of the small cartridge is smaller than the diameter of the turntable so that the mounting and chucking of the disk cannot be performed.

In addition, the recognition terminals installed in the 12cm dedicated recording and reproducing apparatus are not inserted into the recognition holes of the small cartridges, and thus have a disadvantage of not recognizing the state of the disc.

When the cartridge case or the small cartridge is inserted into each of the recording and reproducing apparatuses, since the disc state is unconditionally recognized, the disc state is recognized even when the disc and the track and sector are already replaced. As a result, the recording time was delayed.

On the other hand, Japanese Patent Laid-Open No. 9-293349 (disc cartridge and cartridge adapter) has been provided to allow a small cartridge to be inserted into a 12 cm dedicated recording and reproducing apparatus.

However, in the above prior art, although the small cartridge can be accommodated and used in the recording / reproducing apparatus, the state of the disc accommodated in the small cartridge cannot be recognized.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and an object of the present invention is to accommodate a small cartridge containing a single 12 cm disc or 8 cm disc in a single cartridge adapter, and to determine the state of the discs contained inside the cartridge adapter. By changing the recognition hole accordingly, different size discs can be applied to the 12cm dedicated recording and reproducing apparatus, and the compatibility of the cartridge is improved, thereby reducing the economic cost. The present invention provides a recognition hole converting apparatus for a disc housing cartridge adapter capable of recognizing and shortening a recording time of a disc.
