Abstract
It is known to use the leading edge of a film strip to guide the strip through processing apparatus. However, this leading edge may be damaged as the film is loaded into and unloaded out of a camera. Described herein is a film unloading device in which a curved guillotine blade (240) is used to provide a newly cut leading edge by which a film strip can be guided through processing apparatus. The guillotine blade (240) is reciprocated between a rest and an operative position by a motor which operates in one direction only. The blade (240) is mounted on a rotating drum (250) by means of a crank pin (258), the drum being rotated through 180.degree., in the direction indicated by arrow 252, to move the blade (240) from its rest to its operative position and then through a further 180.degree. to move the blade (240) back to its rest position.
