ABSTRACT:
A cassette of the type having opposing interior surfaces relatively movable toward and away from each other to prevent and permit, respectively, movement of a photographic sheet therebetween, and having at one end an opening through which the sheet can pass along an exit path, has at its opposite end a device engageable with a corner of the sheet remote from the opening and movable at an angle with the exit path to urge the sheet obliquely toward and against a side wall of the cassette, so as to induce buckling of the sheet and consequent separation thereof from the interior surfaces, thereby facilitating succeeding movement of the sheet along the exit path and out through the opening. The device is externally accessible for manual actuation, and the extent to which it can be moved without encountering sheet resistance indicates, visually and tactilely, whether or not a sheet is in the cassette.
