Film handling apparatus control system

A control system for apparatus adapted to process and project film maintained on supply and take-up reels contained within a cassette, said control system comprising:

• an operating cycle selector for programming the control system for either an unprocessed-film operating cycle or a processed-film operating cycle;
• a logic unit having plural logic modes for programming the sequence and execution of plural operational modes of said apparatus during an operating cycle;
• reel drive control means having plural drive control modes adapted to be programmed by said operating cycle selector and said logic unit;
• and
• mode change actuator means responsive to cessation of film movement for changing the logic mode of said logic unit in response to a cessation of film movement.

A control system for apparatus adapted to process and project film maintained on supply and take-up reels contained within a cassette, said control system comprising:

• an operating cycle selector for programming the control system for either an unprocessed-film operating cycle or a processed-film operating cycle, said unprocessed-film operating cycle including sequentially the following operational modes,
• a take-up mode in which the apparatus is programmed to advance unprocessed-film onto the take-up reel,
• a develop mode in which the apparatus is programmed to transport the film from the take-up reel to the supply reel for processing in transit to the supply reel,
• a mandatory project mode in which the processed-film is transported from the supply reel to the take-up reel with a projection lamp energized for simultaneously drying and projecting the film, and
• a rewind mode in which the projected film is rewound onto the supply reel following which the apparatus is de-energized and the cassette ejected
• said processed-film operating cycle including sequentially the following operational modes,
• a project mode in which the film is transported from the supply reel to the take-up reel and projected, and
• a rewind mode in which the projected film is rewound onto the supply reel following which the apparatus is de-energized and the cassette ejected;
• a logic unit having plural logic modes for programming the sequence and execution of plural operational modes of said apparatus during an operating cycle;
• reel drive control means having plural drive control modes adapted to be programmed by said operating cycle selector and said logic means;
• and
• mode change actuator means responsive to cessation of film movement for changing the logic mode of said logic unit in response to a cessation of film movement.

A control system for apparatus adapted to process and project film maintained on supply and take-up reels contained within a cassette, the cassette having indicator means for indicating whether the film is processed or unprocessed, said control system comprising:

• an operating cycle selector for programming the control system for either an unprocessed-film operating cycle or a processed-film operating cycle;
• a logic unit having plural logic modes for programming the sequence and execution of plural operational modes of said apparatus during an operating cycle;
• reel drive control means having plural drive control modes adapted to be programmed by said operating cycle selector and said logic unit;
• and
• mode change actuator means responsive to cessation of film movement for changing the logic mode of said logic unit in response to a cessation of film movement,
• a. in said unprocessed-film cycle programmed by said cycle selector,
• i. said logic unit functions to first condition and actuate said apparatus for a take-up mode comprising advancement of exposed film onto the take-up reel,
• ii. upon cessation of said film advancement onto the take-up reel, said mode change actuator means and said logic unit cooperate to condition and actuate said apparatus for a develop mode comprising transport of the film from the take-up reel to the supply reel without exposure to ambient light for in-transit processing of the film,
• iii. upon cessation of said film transport in said develop mode, said mode change actuator means and said logic unit cooperate to condition and actuate said apparatus for a mandatory project mode comprising transport of the film by a projection shuttle in projection direction with a projection lamp energized for simultaneously drying and projecting said film,
• iv. upon cessation of said film transport in said project mode, said mode change actuator means and said logic unit cooperate to condition and actuate said apparatus for a rewind mode to rewind the film onto said supply reel, and
• v. upon cessation of said film rewind into said supply reel, said mode change actuator means and said logic unit cooperate to condition and actuate said apparatus for off mode in which the apparatus is de-energized and the cassette is ejected,
• b. in said processed-film cycle programmed by said cycle selector,
• i. said logic unit is effective to first condition and actuate said apparatus for a project mode comprising transport of the film by a projection shuttle in projection direction with a projection lamp energized for the film,
• ii. upon cessation of said film transport in said processed-film cycle project mode, said mode change actuator means and said logic unit cooperate to condition and actuate said apparatus for a rewind mode to rewind the film onto said supply reel, and
• iii. upon cessation of said film rewind in said processed-film cycle rewind mode, said mode change actuator means and said logic unit cooperate to condition and actuate said apparatus for off mode in which the apparatus is de-energized and the cassette ejected.
