Manual override for self-processing camera - has sliding control which disengages servo-motor and drives rollers directly by direct ratchet drive

摘要

The self processing camera has the processing rollers (16) driven by a servo motor via a reduction gearing. A manual override has a sliding control (20) which disengages the servo drive in the first part of its movement and then couples a direct ratchet drive to the roller with the remaining part of the movement. The first part of the manual control enables the user to free the rollers for cleaning, without danger of the servo operating and jamming the cleaning cloth in the rollers. The manual control enables the camera to be used when the servo battery is dead.
