ABSTRACT:
An image data processing apparatus for managing a plurality of document images comprising a scanner for reading in document images as electric image data, a volatile memory for temporarily registering the image data, a non-volatile memory device, such as an optical disk, for storing the image data, a character recognition device for recognizing a character put in a predetermined area of the image data scanned by the scanner, and then creating coded data corresponding to the character. It is determined whether or not the actual current page number of a current document, which is recognized by the character recognition device, is sequential with the previous page number of a document image read in immediately before the current document image. The storage of each document image in the non-volatile memory device is controlled by a determination result.
