A currency note identification system comprises a line sensor generating a scanning signal corresponding to the printed pattern on a currency note, an adder for summing picture element signals in the scanning signal from the line sensor for each scanning line, and a detecting circuit for detecting the leading and trailing edges of a printed section of the currency note from the sum signal output of the adder. Printed pattern data for printed patterns at predetermined positions with respect to th...

Method and apparatus for validating banknotes. In some countries, genuine banknotes are provided with a security thread embedded in the banknote, but partially exposes at regularly spaced regions along its length by windows. The windows have a width greater that the security strip itself. The increased transmissivity of the banknote in the infrared region is utilized to detect the presence of such windows to validate the banknote. If the required variation in transmissivity is not detected, the ...

In one preferred embodiment, a method of reading indicia disposed on a substrate moving relative to a reader, the indicia being parallel to and at a known fixed distance from a linear portion of the substrate, and the indicia normally moving relative to the reader along a fixed plane which passes through the reader, the method including; optically sensing the position of the linear portion relative to the reader; and in response to optically sensing the position of the linear portion, adjusting ...

Disclosed is a system for processing documents in a two pass arrangement. During the first pass, an image is stored along with a digital image signature relating to a portion of said image. On the second pass the image signature is compared with stored image signatures seeking a unique match. If that unique match is found, the associated record stored is used for controlling the function of the document processing system, for example, printing an amount field or sorting the document into a selec...

A paper discriminating apparatus has a data correction unit for generating image data associated with non-sensed areas, which are not detected by any of the sensor devices constituting a line sensor, and is capable of contributing to reduction of the sensor devices without producing any additional dictionary data.

In an image forming system, a digital copying machine, which is requested to determine image data, stores determination history data including a result of determination in its memory when the result indicates that the image data are prohibited to be copied, and transfers the determination history data to a digital copying machine of a requesting end, and also transfers the determination history data automatically or as requested to other digital copying machine, a central image formation control...

A bill validator of master-slave type is provided for easy downloading. A master discriminating circuit (40) is switched from a validating mode to a master mode by operation of the master mode switch (48) to forward the download information to a slave discriminating circuit (40) according to the download program. The slave discriminating circuit (40) is switched from a validating mode to a slave mode by operation of the slave mode switch (49) so that the download information from the master disc...

A method for automatically locating and recognizing amount data on a document by scanning the document to first locate a particular symbol, such as a dollar sign "$", and then using the located "$" to determine the document area containing the amount data to be recognized. Elements of the "$" symbol and amount characters are extracted from a gray-level image using binary seed and mask images derived using different gray-level thresholds. Operation is such that black pixels found in the higher th...

A currency counting and discrimination device comprises an input receptacle for receiving a stack of currency bills to be discriminated, a discriminating unit for discriminating the denomination of the currency bills, and one or more output receptacles for receiving the currency bills after being discriminated by the discriminating unit. The device further comprises a transport mechanism for transporting the currency bills, one at a time, from the input receptacle past a sensor of the discrimina...
