Apparatus for automatically classifying of to a film composite strip composite roll films and regroup of films of the same in the same format existing film composite strips

摘要

PURPOSE:To automate processing operation by cutting a negative film differing in image plane size from preceding and following negative film under electric control by an optical detector which detects the image plane side and connection parts of a negative film. CONSTITUTION:Long-sized negative film 1 is fed into the titled device from lead-in part 2 of this device and automatically separated and sorted by image plane types of negative films, and negative films equal in image plane size are connected again and taken up around rolls 3 and 3'. Optical detector 5 provided to said lead-in part 2 consists of detection part 5' for the image plane size of the negative film and detection part 5'' for the connection of the negative film. While detection part 5'' detects a position of the most inferior light transmission, the image plane size detection part starts detection to detect a position of the most superior light transmission. Then, electric signals are sent to controller 15 to discriminate the type of the image plane size, and the negative film is cut by automatic cutting device 9.
