<p>PURPOSE:To make cassette ejection quantity at the time of large cassette ejection almost same as that of a medium or small cassette and to execute stable operation when the cassette is ejected by providing a cassette ejection quantity adjusting mechanism to adjust the cassette ejection quantity from a cassette insertion port. CONSTITUTION:In the process of cassette unloading, when an outer cassette holder 3 raises a vertical stroke from a cassette loading position by a driving motor and moved to a position where the vertical stroke is moved to a horizontal stroke, this position is detected by an outer mid position detection sensor 58. Only when it is detected by a cassette class detection sensor 56 that the cassette is large, the move of the outer cassette holder 3 is stopped by the cassette ejection quantity control mechanism and only an inner cassette holder 4 is allowed to move from a cassette mount side position Y to a cassette insertion port position X. Thus, when the large cassette is ejected, the ejection quantity from the cassette insertion port can be made almost same as that of the medium or small cassette and the stable operation can be executed when the cassette is ejected.</p> |
