Abstract
A disc cartridge that requires no metal guide member and therefore can be easily assembled. With conventional disc cartridges, the metal guide member made of a stainless sheet or the like must be inserted in the case, requiring a number of parts and assembly processes. In addition, the expensive metal guide member makes the final product extremely costly. Especially, an assembly process for assembly the guide member into the case by putting the guide member through the guide slider and the pair of sliders is difficult to automate, thereby reducing productivity. Further, there is a problem that the compression coil spring locked between the sliders is easily detached during assembly process.
