<p>PURPOSE:To securely load each cassette into a prescribed loading position by providing a misinsertion preventing member to be engaged with a misinsertion preventing groove in a position corresponding to a standard cassette and a small size cassette at their height respectively. CONSTITUTION:There is a holder 300 in a cassette inserting standby position at the time of loading the cassette, and when the standard or small size cassette inserted from a cassette inserting hole 150 is loaded into this holder 300, it is detected by a cassette detecting switch that the cassette is loaded, so that a driving motor 401 is driven, and left and right main gears 408 and 411 are rotated and then operating arms 413 and 414 are also rotated. Consequently, guide pins 301a and 301b are guided along grooves 111 and 121, and the holder 300 is moved from the cassette inserting standby position to a 1st prescribed loading position at the time of loading the standard cassette, and to a 2nd prescribed loading position situated slightly higher than the 1st prescribed loading position at the time of loading the small size cassette. By this method, each cassette is securely loaded into its prescribed loading position.</p> |
