ABSTRACT:
Described herein is a film extraction unit for use in a loading device for photographic processing apparatus. The unit comprises an unloading station (12) into which a film cassette (100) is positioned with the film leader extending therefrom to lie between rollers (26, 28). Roller (26) is a pinch roller which engages with drive roller (28) to transport the film out of its cassette. Drive roller (28) is driven by a motor via a clutch arrangement so that once all the film (102) has been extracted from the cassette (100), the clutch will slip allowing the motor to continue to rotate whilst the drive roller (28) becomes stationary, thereby preventing damage to the film (102).
