<p>PURPOSE:To make it possible to speedily find forgery or falsification of data, by reading business form data printed in an invisible state by a special device, and processing the data thus read. CONSTITUTION:A visible-printing part 41 is provided at an upper part of the face side of a business form paper 20. An invisible-printing area 42 provided below the visible-printing part 41 is coated with a transparent heat-sensitive agent capable of reflecting IR rays when being heated, and business form data is thermally printed in the area 42 so that it is invisible to human eyes. Further, an MiCR printing area 43 for printing business form data in a magnetic ink is provided below the area 42. Business forms 40 thus obtained are stocked in a document hopper 2, and are fed out into a feeding passage 4 by one sheet at a time by a feeding-out machine 3 provided on the operator's side of the hopper 2. The validity of the business form is judged by an invisible area reading head 6, comprising an IR lamp and an image sensor, and an MiCR print reading head 5 which are provided at intermediate parts in the feeding passage. The business form is then fed to either of normal and abnormal document stockers 8, 9 by a flapper 7 according to the validity thereof.</p> |
