Arrangement for opening and closing a closure of an opening in a film cassette

Abstract

An arrangement for opening and closing a closure of an opening in a film cassette includes a rotary member which has a cam surface provided thereon and a connecting link articulated thereto. A cam follower roller is mounted on a mounting plate which is mounted on a support for pivoting about an axis parallel to the direction of displacement of the closure between its open and closed positions, and the connecting link is loosely connected to a carriage which is supported on the mounting plate for displacement along the path of displacement of the closure and carries an entraining member which engages the closure upon pivoting of the mounting plate from its retracted to its extended position toward the respective cassette and entrains the closure of movement with the carriage, during the rotation of the rotary member. The entraining member is mounted on the carriage by means of a lever which cooperates with a micro switch that reverses the rotation of the rotary member when the lever is pivoted as a result of jamming of the closure.
