Encasing mechanism for a cassette enclosing a magnetic record medium

摘要

In an encasing mechanism for a cassette enclosing a magnetic record medium, the mechanism provides a cassette with a recess formed at a first surface of the cassette to identify first and second surfaces and first and second edges of the cassette, a case main body, and a cover coupled rotatably to the case main body to be openable relative to the case main body, in which the cover includes at least one projection formed on an inner surface of the cover. The projection is fitted into the recess so that the cover is closed relative to the case main body in an inserted arrangement of the cassette into the case main body. The encasing mechanism is capable of encasing the magnetic record medium cassette only when the cassette is correctly positioned in the case main body.
