Pivotably mounted on a pivotable handle (1) is a lever (2) to which a spring (3) is applied clockwise. An arm (2b) of the lever (2) is situated on a pivoted arm (4, 4a) which engages by means of a one-way coupling in a hub (12b, 12c) of a film disc (12). In the event of a feed blockage, another arm (2a) is supported on a fixed stop (7k) or runs after the last exposure against a fixed stop (7l) and prevents triggering. When operated, the handle (1) cocks a drive element (6) with an impact arm (6c) which is held on a release lever (10). Engaging directly on the handle (1) is a spring-loaded, pivotable follower member (11) whose follower (11a) is assigned to notches (12a) of the film disc (12). Upon operation of the handle (1) in the direction "A" of the arrow, the pivoted arm (4) rotates the film disc (12), and the release lever (10) releases the impact arm (6c). The latter strikes with an impact hammer (6d) on a piezoelectric generator (8), and a shutter blade (9) is thrown up by a drive hammer (6e) of the impact arm (6c). The returning handle (1) resets the device to its initial position. <IMAGE>
