Abstract: An improved photographic cassette is disclosed having a pressure plate adjacent a rear cover wall thereof provided with laterally extending tabs on opposite side edges thereof. The cassette further has a floating plate adjacent a front cover wall which is unsecured to the front cover wall at least at all portions thereof except the center portion. The floating plate has ears laterally extending from the side edges thereof in register with and spaced from the tabs. The cassette has push-bar mechanisms adapted when the push-bar mechanisms are moved to an extended position to enter the space between the ears and tabs and to engage the tabs and move the pressure plate toward the rear cover wall, and to override the ears for latching the floating plate to the front cover wall whereby the pressure and floating plates are spaced apart for allowing a sheet to freely move into or exit the cassette.
