Disk cartridge

Abstract

A recess is formed in a tray of a disc case. A peripheral wall portion of the recess is formed having disc supporting portions that support a disc in a manner such that the recording surface of the disc is floating. Spring elements are arranged along slots that are formed in the peripheral wall portion. Each spring element is formed having a protuberance and a guide surface. As the disc is inserted into the recess, the spring elements bend with their respective guide surfaces touched by an outer peripheral portion of the disc. The outer peripheral portion of the disc moves into the space inside the protuberances of the spring elements. When the disc is in the recess, the protuberances prevent the disc from slipping out of the recess.

Description

technical field [0001] The invention relates to a disc case for storing media discs, such as compact discs, so-called CD discs, digital versatile discs and the like. Background technique [0002] In conventionally used disc cases for storing media discs such as optical discs, upper and lower plastic shells are usually rotatably connected to each other by hinge pivots. A circular boss (center boss) is formed at the center of the lower case of this conventional disc cartridge. The disc is placed in such a way that when the center hole of the disc is placed on this center boss, the recording surface of the disc is floating [0003] Disk cases used to store compact discs of music, literature, etc. require a specific elegant design to distinguish the contents of these discs from other discs. If the center boss is formed on the chassis like the conventional disk case, it inevitably restricts the design of the case. [0004] Perhaps, a flat chassis without a central boss could b...

Problems solved by technology

As such, existing autoloaders cannot be used with cartridges that require disks to be inserted from the side of the tray
