Automatic recording method for page number during microfilm proofreading

Abstract

Abstract PURPOSE:To find the misrecording of a page code in each frame of a microfilm, and to evade an error in the page arrangement of a book with complete printing, by comparing the number of pages exposed in a blank of an original image with that in the image. CONSTITUTION:On a microfilm 4, one page of an original to be bound is reduced and copied as one frame, and a page code for frame selection is recorded in each frame; and page codes of respective frames of the running microfilm 4 are read by a code reader 6 arranged at an adequate place. On a photosensitive material 7 whose one end is wound around a reel 8 arranged on the left side of a base 2, one frame of the original reduced and copied on the microfilm 4 is enlarged and projected by a light source 3 to from an image 12. A light generation type display device 13 which displays a numeral corresponding to a readout signal by the reader automatically records a page number 15 in a blank of the image 12 which corresponds to the readout signal of the photosensitive material 7.
