Abstract

A bill discriminating apparatus including a detected data memory for temporarily storing data corresponding to at least one line of a bill photoelectrically detected by at least one scan of a photoelectrical detector, a control device for detecting the number of the detected data for each line of the bill to be stored in the detected data memory and detecting a condition of feeding based on the detected data of the first line of the bill to be stored in the detected data memory, a data count memory for storing the number of the detected data corresponding to each line of the bill detected by the control device, a bill feed condition memory for storing information detected by the control device and a detected pattern memory for storing the pattern of the bill based on the detected data stored in the detected data memory. The control device writes the detected data stored in the detected data memory in the detected pattern memory based on the number of the detected data corresponding to each line of the bill stored in the data count memory and the information stored in the bill feed condition memory so that rectangular patterns can be stored in the detected pattern memory.

Claims

1. A bill discriminating apparatus having photoelectrical detecting means for scanning bills being fed along a bill feeding path with light in the direction perpendicular to the bill feeding direction and photoelectrically detecting light transmitted through or reflected by the bills and bill discriminating means for comparing a detected pattern produced based on an amount of light transmitted through or reflected by the bills detected by said photoelectrical detecting means with reference patterns and discriminating denominations, genuineness and/or condition of the bills, said bill discriminating apparatus comprising detected data storing means for temporarily storing data corresponding to at least one line of a bill photoelectrically detected by at least one scan of said photoelectrical detecting means, control means for detecting the number of said detected data for each line of the bill to be stored in said detected data storing means and detecting a condition of feeding of the bill based on the detected data of the first line of the bill to be stored in said detected data storing means, data count storing means for storing the number of the detected data corresponding to each line of the bill detected by said control means, bill feed condition storing means for storing information detected by said control means and detected pattern storing means for storing the pattern of the bill based on the detected data stored in said detected data storing means, said control means being able to write the detected data stored in said detected data on the number of the detected data corresponding to each line of the bill stored in said data count storing means and the information stored in said bill feed condition storing means so that rectangular patterns can be stored in said detected pattern storing means.

2. A bill discriminating apparatus in accordance with claim 1, wherein said control means is able to detect whether or not an oblique trouble occurs and whether a front left edge of said bills or a front right edge of the bills is precedent and inputting the thus detected result into said bill feed condition storing means.

3. A bill discriminating apparatus in accordance with claim 1, wherein said control means detects when oblique travel occurs when the number of detected data greater than zero for the first line of the bill is smaller than a predetermined number.
