Abstract:
A disc cartridge assembling apparatus in which a protuberance formed on the inner surface of one of cartridge halves of a thermoplastic resin making up a main cartridge body unit is passed through a through-hole formed in the other cartridge half in register with said protuberance and in which a distal end of said protuberance is thermally deformed to interconnect said cartridge halves, comprising:a holding mechanism for holding said cartridge halves so that, with the cartridge half formed with said protuberance being placed below the other cartridge half, said other cartridge half being mounted on said cartridge half formed with said protuberance by passing said protuberance through said through-hole and for holding said upper and lower cartridge halves together;a caulking head having a recess on a surface thereof abutted against said protuberance, said caulking head enclosing a heating mechanism, said caulking head being adapted to compress against the distal end of said protuberance of said cartridge half exposed through said through-hole of said other cartridge half;a movement mechanism for thrusting said caulking head, heated to a temperature capable of thermally deforming said thermoplastic resin, against the distal end of said protuberance to deform said protuberance and for moving said caulking head away from said protuberance; anda cooling mechanism for cooling said caulking head.
