Film image projecting apparatus for handling a roll film containing a plurality of rows of frames

A film image projecting apparatus for handling a duplex roll film containing two rows of frames, said apparatus comprising:

• a projecting optical system for projecting images contained in said roll film;
• a first frame advance means for transporting said roll film frame by frame longitudinally thereof;
• a second frame advance means for moving said roll film by one row transversely thereof;
• and
• control means for actuating said second frame advance means each time said first frame advance means transports said roll film by one frame.

A film image projecting apparatus for handling a duplex-type roll film containing two rows of frames, said apparatus comprising:

• a screen for displaying images;
• copying means for copying projected images on recording medium;
• film transport means for longitudinally transporting said roll film containing two rows of frames;
• a projecting optical system for projecting images contained in said roll film selectively onto said screen and a photoreceptor of said copying medium;
• film moving means for transversely moving said roll film so as to selectively coincide the center line of either of said two rows with an optical axis of said projecting optical system;
• and
• control means for Controlling said copying means, film transport means and film moving means so that the frame images in one row and in another row are alternately copied.

A film image projecting apparatus for retrieving information by searching blip marks arranged laterally of frames in a roll film, said apparatus comprising:

• film transport means for longitudinally transporting said roll film including said blip marks arranged laterally of said frames;
• film moving means for transversely moving said roll film;
• judging means for judging whether said roll film contains a plurality of rows of frames;
• a projecting optical system for projecting images contained in said roll film;
• and
• control means operable when said roll film is judged by said judging means to contain a plurality of rows of frames, for enlarging an illuminated area on said roll film.
