ABSTRACT:
A disc cartridge capable of readily and simultaneously accomplishing assembling of a shutter and mounting of the shutter on a casing to improve operating efficiency and workability in manufacturing of the disc cartridge. The disc cartridge includes a shutter formed of a slider and upper and lower shutter plates into a U-shape and a shutter assembling and mounting mechanism. The mechanism includes a pair of engagement holes provided on each of shutter plates and a pair of projections provided on a slider corresponding to each shutter plate and engaged with the holes to carry out secure positioning between the slider and the shutter plate. The mechanism also includes a fit-in element provided on each of the shutter plates and a fit-on element arranged on the slider corresponding to each fit-in element. The fit-in element is securely fitted in the fit-on element to accomplish joining between each of the shutter plate and the slider. Fitting between the fit-in element and the fit-on element is carried out substantially simultaneously with engagement between the holes and the projection.
