B. Summary of the Invention The present invention provides a cassette storage shelf applied to a cassette autochanger, etc., in which a cassette is inserted into the cassette storage section from the cassette transfer machine side, and the cassette in the cassette storage section is ejected by an ejecting means by an operation from the operator side. When ejecting the cassette to the operator side, the ejecting mechanism is not activated until the eject means is correctly engaged with the end of the cassette on the cassette transfer machine side upon completion of insertion of the cassette from the cassette transfer machine side into the cassette storage section. By prohibiting the means from ejecting the cassette to the operator, it is possible to prevent erroneous eject operations by the operator.

C. Prior Art The applicant of the present invention has filed a prior application for a cassette storage shelf for a cassette autochanger using a video cassette/nod.
