<p>PURPOSE:To set automatically a cassette in a miserasion preventing state for a switch when the cassette is taken out of a VTR by providing a miserasion preventing member which opens and closes an aperture at the outer circumference of the cassette in response to the shift of the switch material within a space. CONSTITUTION:A release bar 8 contains a hook part 9 at its tip and is energized downward by a spring 14 connected to the tip. Then a roll 11 touches the side wall of a cassette and is supported by a support member 12 which is fitted with a play into a slit 10. when a video cassette with which the recording is through is taken out of a VTR, a set button 13 is pushed before an ejecting operation. Thus the upper end of the bar 8 is pushed, and a hook part 9 of the bar 8 is hooked to a projected part 6 of a switch member 5. The button 13 is maintained in a state where the bar 8 is pushed, and then the cassette moves toward an arrow B of the figure 5 by an ejecting operation. As a result, the member 5 is slided toward the lower part of a space 4. Thus the cassette is set without having miserasion.</p> |
