IPC: G06T7/00
Filed: 1998-05-29
Abstract: PROBLEM TO BE SOLVED: To provide an illegal copy prevention device where a copying machine cannot conduct normal copying processing in the state that the illegal copy prevention device is removed from the copying machine so as to prevent in advance an illegal copying act. SOLUTION: Image information read by an image read section 10 is fed to an image control section 11, where image conversion required for printing is conducted and an image output section 12 prints out an image based on converted image information in a copying machine, on which an illegal copy prevention device is mounted. The illegal copy prevention device is placed in series between the image read section 10 and the image control section 11 and a part of image information is fed to the image control section 11 through the illegal copy prevention device via a path of signal lines S3, S4. Thus, when the illegal copy prevention device 14 is removed from the copying machine, since regular image information to be fed via the signal lines S3, S4 is not fed to the image control section 11, the copying machine cannot conduct normal copying processing so as to prevent illegal copying.

The reflection direction differs depending on the face A or B where the rays are first enter. Therefore, the reflected rays are divided into symmetric two directions about the incident direction of rays as the center line, and the rays are reflected in the directions deviated by ±2δ deg. angle, wherein δ deg. is the difference from 90 deg. of the included angle between the face A and face B of the mirrors, and the split angle between two rays becomes 4δ deg..
