<p>PURPOSE:To facilitate discrimination between VHS cassette and second cassette and to realize a compatible machine. CONSTITUTION:A slider 2 is integrated with a holder for holding a cassette 1 and carrying the cassette 1 to a loading position. The cassette 1 is held correctly and horizontally with respect to slider 2 when an erroneous insertion preventing groove 6 in the cassette 1 engages with a protrusion 3 on the slider 2. In other words, the cassette 1 can be loaded only from the direction perpendicular to the protrusion 3 provided on the slider 2.</p> |
