DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
The present invention relates to a document handling apparatus, more particularly, to an apparatus for recording on paper patterns printed on documents or the like.
BACKGROUND OF THE INVENTION
Bill validators are used in various fields including automatic vending machines, ticket venders, automatic money deposition machines and so forth. The fundamental techniques for validation of bills or bank notes are mainly divided into optical and magnetic validation methods. In the optical validation method, photosensors are utilized to measure an amount of light reflected on a surface of a bill or permeated through a bill so that dimensions and printed conditions of the bill are represented by electric signals from the photosensors in order to decide authenticity of the bill. Also, in the magnetic validation method, magnetic sensors are employed to measure magnetic characteristics of the bill for judgment of the authenticity. There are some cases of adopting a stricter combined method of the optical and magnetic validation as occasion demand.
For example, Japanese Patent Disclosure No. 60-77287 shows a bill handling apparatus which includes a bill conveyor device and a magnetic head for bill validation; and U.S. Pat. No. 4,628,194 teaches a bill validator with optical and magnetic sensors.
under current heavy international traffic, there are many cases that require bills to be exchanged between local and foreign money. If exchanged money includes counterfeit bills, unexpected troubles would occur with owners of the money in good faith. Accordingly, at the time of finding out such fake notes, it is convenient to identify or confirm a banking facility or exchanger agency who exchanged the bills before. However, it in fact is quite difficult at present to record all symbols or numbers printed on exchanged bills and to reserve these records at the banking facilities or exchanger agencies.
Accordingly, an object of the present invention is to provide an apparatus for automatically recording on printing paper symbols printed on documents, removing the above mentioned defects in prior arts.
DISCLOSURE OF THE INVENTION
The apparatus for recording symbols of documents according to the present invention, includes conveyer means for transporting a document along a passageway; image sensor means provided adjacent to the passageway for converting symbols printed on the document into electric signals; printer means for printing operated according to output signals of the image sensor means and validator sensor; and read controller means for activating the image sensor means when the symbols printed on the document pass through the image sensor means. In an embodiment of the present invention, the document is a bill. The read controller means includes a pattern recognition device for reading the symbols printed on the document by pattern-recognition of the output signals of the image sensor means.
The conveyer means includes a rate regulator so as to reduce conveyed speed of the document when the symbols printed on the document pass through the image sensor means, and to increase the conveyed speed of the document after the symbols printed on the document pass through the image sensor means. The read controller means detects inserted condition of the conveyed document and forwards stored information in the form of inverted arrangement of the output signals to the printer means when the document is conveyed in a reverse direction.
Validator means is provided adjacent to the passageway for producing output signals to validate authenticity of the document. The read controller means has a memory device for storing the output signals from the image sensor means and for forwarding stored information to the printer means. The read controller means erases the information stored in the memory device when the validator means does not detect the authenticity of the document.
The read controller means includes symbol detector means for detecting the read condition of the symbols read by the image sensor means. T
