CAMERA FILM UNIT PROCESSOR WITH PROTECTIVE RATCHET ASSEMBLY

摘要

A film advancing-fluid spreading apparatus including a pair of pressure-applying members having juxtaposed surfaces rotatably mounted for contacting and advancing upper and lower surfaces of an exposed film unit therebetween to distribute a layer of a processing composition upon a photosensitive layer of the film unit. One of the pair of pressure-applying members includes a pinion axially coupled thereto which receives energy from a motor connected to a power train whereby energy is transferred from the motor to the pinion to rotate the pressureapplying member in a predetermined direction. The power train includes an energy transferring system and a ratchet assembly which permits a transfer of energy from the energy transferring system to the pinion when the film advancing-fluid spreading apparatus is operating in a driving mode, and substantially prevents the transfer of energy from the pinion to the energy transferring system when the pressure-applying member having the pinion axially coupled thereto is manually rotated in the predetermined direction.
