Abstract

The present invention provides an image processing apparatus which not only judges the occurrence of multiple feeding with a high accuracy, but also can identify later the location of occurrence of the multiple feeding even if the document reading operation is continued after detecting the occurrence of a multiple feeding. The detection device (the detecting and reading section 53) detects the information storage media attached to the documents which are being fed one sheet at a time by the automatic document feeder 20 and from which the images are being read out. The determining section 56 detects based on the result of this detection the occurrence of multiple feeding in which a plural number of sheets of the document are conveyed in an overlapping state. The information recording section 54 writes the multiple feeding information, indicating that a multiple feeding has occurred, in the information recording medium of the document that was judged to have been fed in an overlapping state.

Dependent claims

An image processing apparatus, comprising:

an image reading section which reads an image on an original document at a reading position and obtains image data corresponding to the image;
an original document conveying section which conveys the original document to the reading position by feeding the original document separately from a bunch of a plurality of the original documents;
a detecting section which detects an information recording medium on the original document being conveyed by the original document conveying section;
and
a determining section which determines existence or nonexistence of multiple feeding, where a plurality of original documents are conveyed in an overlapping state, based on a detection result of the detecting section.
