Patent ID: 7428121

Claim:
A method of locking a tape cassette housing of tape cassette, comprising: pressing an upper surface of the tape cassette housing descendly towards a deck chassis; pivoting a second link member along a second guide protrusion in a direction in which a lower end of a first link member ascends; slidably connecting a first guide protrusion of the deck chassis to a first guide rail of a lower end of a first link member, wherein the first and the second link members interactively move, allowing the tape cassette housing to closely contact the deck chassis, whereupon a guide surface of a locking lever slides along an edge formed at a side of a locking protrusion until the edge comes into close contact with a locking recess of the locking lever; pivoting the locking lever about a first hinge such that a resilient member attached to the locking lever is expanded; and locking the tape cassette housing when the resilient member recovers as the tape cassette housing substantially contacts the deck chassis inserting the locking protrusion into the locking recess.
