Cartridge for accomodating optical discs of different sizes

A cartridge to accommodate first and second optical discs of different sizes, comprising:

• a main case comprising
• a main shutter,
• an upper plate, and
• a lower plate coupled to the upper plate to accommodate the first optical disc, the lower plate forming a first longitudinal opening by cooperating with the upper plate;
• a cover pivotably mounted on said main case;
• an auxiliary case comprising an auxiliary shutter,
• wherein said auxiliary case accommodates the second optical disc having a smaller diameter than that of the first optical disc, and
• wherein said main case accommodates said auxiliary case;
• means for opening the auxiliary shutter and the main shutter;
• means provided in said main case for accommodating said auxiliary case in said main case;
• and
• means provided in said main case to support said auxiliary case.

A cartridge, loadable in an optical disc recording/reproducing device, to accommodate first and second optical discs having first and second diameters, respectively, the first diameter being greater than the second diameter, the cartridge comprising:

• an auxiliary case comprising an auxiliary shutter to accommodate the second optical disc having the second diameter;
• and
• a main case comprising a receiving opening,
• wherein said main case accommodates
• the first optical disc having the first diameter if the first optical disc is to be read from or recorded on by the optical disc recording/reproducing device, and
• said auxiliary case if the second optical disc is to be read from or recorded on by the optical disc recording/reproducing device.

A cartridge to accommodate first and second optical discs of different diameters, comprising:

• an auxiliary case to accommodate the second optical disc having a second diameter, comprising
• a first opening extending along a radius of the accommodated second optical disc, and
• an auxiliary shutter slidably movable to cover and expose said first opening;
• and
• a main case to accommodate the first optical disc having a first diameter greater than the second diameter and said auxiliary case, said main case comprising
• a second opening extending along a radius of the accommodated second optical disc and the radius of the first optical disc, and
• a main shutter connected to said auxiliary shutter to expose and cover said second opening, and moving said auxiliary shutter to correspondingly expose and cover said first opening if said auxiliary case is accommodated in said main case.
