ABSTRACT:
An adapter for a miniature type tape cassette has an external form and size smaller than those of a standard type tape cassette. The miniature type tape cassette is primarily designed for a recording and/or reproducing apparatus of a type different from a standard type recording and/or reproducing apparatus which is originally designed for the standard type tape cassette. The miniature type tape cassette has an erroneous erasure preventing tab which operates together with a detection mechanism of the recording and/or reproducing apparatus of the different type. While the standard type recording and/or reproducing apparatus has a detection mechanism which is primarily designed to operate together with an erroneous erasure preventing tab of the standard type tape cassette. The adapter comprises an adapter case having an external form and size substantially equal to those of the standard type tape cassette, an accommodating part for accommodating the miniature type tape cassette, and an erroneous erasure preventing mechanism provided within the adapter case. The erroneous erasure preventing mechanism has a tab part which moves at a position capable of operating together with the detection mechanism of the standard type recording and/or reproducing apparatus in response to the existence and non-existence of the erroneous erasure preventing tab of the miniature type tape cassette accommodated within the accommodating part.
