PURPOSE:To equalize the load on casset cover by providing bag-shaped pits on the edge of attaching leg of the casset cover and placing wire spring to both sides, and by supporting the center of the wire spring by the U-shape rib of the front cabinet. CONSTITUTION:On the both sides of a cassette cover 1, attaching legs 2 are provided which have a pit groove 2-b as a rotary fulcrum part, and both end edge of a wire spring 4 are attached to a bag-shaped hole 2-a. An axis 5a of a front cabinet 6 is hooked into the pit groove 2-b, and the cassette cover 1 attached to the front cabinet, and the center of the wire spring 4 is supported by the U-shape rib 3 provided on the front cabinet 6. When the casset cover 1 is opened, the wire spring has a slight sag but when the cover is closed, the sag of the wire spring becomes large. Therefore uniform load is charged on the casset cover, and the phenomenum of uneven loads of right and left will not happen any more.
