Abstract: In a paper sheet processing apparatus comprising a function for determining the state of a paper sheet, an optical sensor generates template data by optically reading the state of an input paper sheet. A template data unit stores template data of a paper sheet. An image processing unit corrects gradation data of the whole paper sheet based on the gradation data of a predetermined area of the paper sheet obtained by the optical sensor. Based on comparison of the corrected gradation data with the template data, the state of the paper sheet is determined.

Abstract: A paper sheets feature detector 20, through which a banknote 21 is carried and passed is provided with a carrying-in sensor part 22, a transmissive and reflective line light sensor 23, a magnetic sensor 24, a thickness sensor 27, and a carrying-out sensor part 28. When a watermark part of the banknote 21 is measured by the line light sensor 23, a watermark pattern is detected by a light transmissive sensor, and that pattern is not detected by a light reflective sensor, the banknote 21 is determined to be a true banknote. Watermark braille is similarly processed. When the thread is detected by the light transmissive sensor and the thread is not detected by the light reflective sensor, the banknote 21 is determined to be a true banknote.

Abstract: When a thickness sensor detects a corner fold in a front end part of the paper sheet being carried, a light sensor checks whether a break exists or not in the front end part. When there is no break, it means the thickness sensor does not detect a corner fold but a foreign matter such as a tape mending a break. When there is a break, it means the thickness sensor detects a corner fold in the front end part. When there is no corner fold, the light sensor checks the front end part. When there is a break, it means there is a corner break but no corner fold in the front end part. When there is no break, it is a normal state. Regarding the back end part, a corner fold is detected in similarly to the foregoing.

Abstract: The image manipulation unit (17) corrects the tilt and color shade of the paper-piece image data obtained by the optical sensor unit (13). The template comparison unit (18) makes the for-comparison banknote image data of each denomination from the paper-piece image data made by the image manipulation unit (17) and the reference data of each denomination stored in the reference data unit (19). And the process of pattern matching of the for-comparison banknote image data with the template with the corresponding denomination stored in the template unit (20) is performed for all denominations, and the denomination with the closest distance between patterns is discriminated as the denomination of the piece of paper. The result of the discrimination is stored in the memory unit (21).

Abstract: In a paper discriminator having the line sensor and the point sensor, data to be obtained by the point sensor correspond to a common coordinate plane to data to be obtained by the line sensor. Thus, in partial data of the papers to be obtained by the point sensor also, a position for the entire surface of the papers of the part can be specified, and it is possible to compare data by the point sensor with reference data prepared in advance. Thus, discrimination precision of the papers is enhanced.

Abstract: The processing apparatus for discriminating bank notes has an insert sensor for detecting the insertion of a bank note, line sensors for sampling the pattern and so forth of the bank note, and a sensor memory in which sampling data collected by means of the line sensors is stored for each line. The insert sensor is provided only at the entrance side of the apparatus. If a bank note is conveyed on one side of the line sensor, the data sampling is started when the insert sensor detects the passage of the bank note; if a bank note is conveyed on the other side of the line sensor, the data sampling is started before the bank note is moved. The pattern image data is generated from the sampling data read out from the sensor memory and a bank note is discriminated by comparing the pattern image with a reference pattern.
