<p>PURPOSE:To securely open a shutter of a cassette even in the presence of some variations in a moving stroke of the shutter by interposing a limiter means between a cassette mounting plate and a loading drive part. CONSTITUTION:The shutter of the cassette is moved until its opening position by moving the cassette mounting plate 57 back and forth against a frame member 39 for restricting a cassette mounting space in its square. Then, a pressing receiver part 90 provided on the cassette mounting plate 57 is pressed by a pressing part 143 provided to the loading drive part, while the limiter means 92 is interposed between the loading drive part and the cassette mounting plate 57. By this method, even when there are variations in the moving stroke of the shutter of the cassette, the cassette mounting plate 57 is finally moved for making assurance via the limiter means 92, and the shutter is moved securely until its opening position, and then such as unreasonable force as to damage the cassette or the subject cassette loader must never be given.</p> |
