<p>PURPOSE:To contrive reduction of the number of parts of a standard cassette and reduction of the cost by using an operation member of a small size cassette retaining mechanism of a holder top board and an operation member of a turning mechanism of a guide plate for the small size cassette in common as a cassette retaining member for the standard cassette. CONSTITUTION:The subject loader is provided with the operation member 364 for bringing the standard cassette under its turnable state at the time of its insertion and for retreating it to an upper part position outside a housing space of the standard cassette and the operation member 375 for turning the standard cassette at the time of its insertion to become under a laterally thrown state approximately parallel with the top board 303 to evade a position of hindrance to its inserting operation. Then, by pushing up both operation members 364 and 375 in accordance with the insertion of the standard cassette, both the operation members 364 and 375 are brought into contact with a leaf spring 305 to be given required elastic force, and also its lower end is abutted against the upper surface of the inserted standard cassette, and hence both operation members 364 and 375 act as the cassette retaining member for the standard cassette. By this method, the need of a dedicated standard cassette retaining mechanism is eliminated, so that reduction of the number of parts and reduction of the cost can be contrived.</p> |
