ABSTRACT:
To provide a recording and reproducing apparatus which permits to use tape cassettes different in not only size but also thickness. In order to make the apparatus cope with the tape cassettes different in size and thickness, there is provided a positioning guide mechanism including a pair of positioning guide members so that a small cassette can be guided at both the side faces on a cassette supporting surface of the cassette holder so as to be depressed and projected by a biasing means, and a pair of side plates at its both sides of a cassette holder so that a large cassette can be guided at its both side faces. If a user is not highly skilled in operating such recording and reproducing apparatus which permits to use tape cassettes different in size and thickness, the apparatus will suffer from risk that the cassettes are erroneously inserted or the user carries out malicious operation. In order to avoid a trouble due to such erroneous insertion, malicious operation or the like, the recording and reproducing apparatus further includes a cassette insertion detecting switch mechanism useful for detecting the insertion of the cassette and leading the cassette into the cassette holder and a holder stopper mechanism composed of a holder unlocking member and a lock member.
