ABSTRACT:
An improved photographic cassette in which the plate and screen adjacent the front cover on the tube side of the cassette is unsecured to the front cover; that is, free floating, thereby achieving more uniform sheet-to-plate contact throughout the entire area of the sheet. The cassette also has a pressure plate and means forming a part of the pressure relieving means for engaging and holding the floating plate against the front cover upon actuation of the cassette pressure relieving means. The floating plate engaging and holding means facilitates separation of the pressure and floating plates and unblocking of the cassette entry slot by the floating plate to allow a sheet to freely enter the slot.
