Abstract
A tape cassette dust door latch, a dust door latch spring assembly and a related method for assembling the dust door latch into the tape cassette. The dust door latch has a lock plate with a boss projecting perpendicularly therefrom and a coil spring with first and second ends, the first end of the spring surrounding the boss and the second end of the spring being a free end. The cassette has an upper half case and a lower half case, the upper half case having an abutment member located in the vicinity of the lock plate, and the lower half case having a means for rotatably receiving the dust door latch. In the method of assembling, first, the dust door latch is inserted into the receiving means in the lower half case, and then the upper half case is assembled onto the lower half case such that the abutment member receives the free end of the coil spring, directs it downwardly, and holds the coil spring in a biased position. This dust door latch, dust door latch spring assembly and the method for assembling the dust door latch into the tape cassette provide more efficient production and automated assembly of tape cassettes.
