ABSTRACT:
An elastic lifter arranged on an inner surface of a casing of a disc cartridge to exert a pressing force on a disc is formed integrally with the casing and into a plate-like shape in such a manner that a proximal end thereof is connected to the casing and a distal end thereof is rendered free. Such construction permits the pressing force to be kept constant for a long period of time and effectively prevents damage to the disc, to thereby substantially improve durability and reliability of the disc cartridge while significantly decreasing the number of parts, facilitating assembling of the disc cartridge, and attains a decrease in manufacturing cost. The lifter may be formed at a proximal end thereof with a decreased thickness, to thereby facilitate bending of the lifter.
