Abstract
An arrangement for opening and closing a film sheet cassette having a bottom element and a top element movable relative to the bottom element between open and closed positions, includes a sliding element guided on the bottom element and movable relative to the top element in a first direction from a first position in which it engages the top element and thereby the latter is retained in the closed position to a second position in which said sliding element disengages from the top element and thereby the latter can move to the open position, a spring urging the sliding element into the first engaged position and an arresting device cooperating with the sliding element and operative for preventing unintentional movement of the sliding element from the first engaged position to the second disengaged position by itself or under the action of impacts, and thereby preventing opening of the cassette.
