<p>The device is arranged in the form of a complete assembly group on two plates (1, 2) screwed together by means of spacer bolts (18). Guide slots (1a, 1b, 2a, 2b) of similar arrangement and design serve for positively guiding a reciprocable carriage (9, 10). The carriage (9, 10) comprises a guide member (9) with guide rollers (12, 13, 33, 34) which are supported on ball bearings, bars (3, 4) being hinged to said guide member which at their other ends are hinged to drivers (5, 6). The drivers (5) are secured to toothed belts (7, 8) guided and driven by gear wheels (16, 30) mounted on the plates. A carrier (10) mounted on the guide member (9) so as to be shiftable, liftable and tiltable supports a pivotally mounted suction plate (11, 22). The guide slots are arranged in a position inclined towards the cassette (27) to be unloaded while the toothed belts (7, 8) are arranged in an angular position opening in this direction. The guide slots (1b, 2b) facing the cassette (27) have in their lower end areas downwardly bent guide sections (1d, 2i) which in connection with the angular arrangement of the toothed belt (7, 8) cause the suction members (22) to be slowed down when being lowered onto the film (30) to be unloaded.</p> |
