Definitions
- the present invention relates to a paper sheet processing apparatus, and more particularly to a paper sheet processing apparatus that discriminates forged tickets.
- the paper sheet processing device is provided with a discrimination unit, which judges the authenticity of paper sheets (banknotes, tickets, etc.) inserted from the system input port.
- the identification unit divides the paper sheet to be inspected into small areas, measures the pattern shape and pattern of each small area with an optical sensor, a magnetic sensor, a thickness sensor, etc., and converts the measured value into a gradation signal, etc. Convert and store.
- the gradation signal is subjected to predetermined image processing to create image data of the entire paper sheet, and the image data is input by comparing and collating with dictionary data created in advance from genuine bills. It is configured to judge the authenticity of the printed sheets.
- the transport direction of the inserted paper sheets is either vertical (longitudinal direction of paper sheets) or horizontal direction (transverse direction of paper sheets) depending on the model.
- the transport direction can be set freely.
- the vertical The dictionary for determining the authenticity of inserted paper sheets and the dictionary for determining the authenticity of horizontally inserted paper sheets are completely different and have different authentication algorithms. It was necessary to develop and maintain the discriminating unit for horizontal loading and maintenance separately, and development costs and maintenance costs were high.
- Threads are made by weaving or weaving special fibers, plastics, or metal-like strips inside or on the surface of the sheet. This thread is a feature that is extremely common in overseas banknotes, and has recently been adopted in Japan as a way to prevent counterfeiting in book coupons and Shinkansen coupons. As described above, threads are classified into fiber threads, metal threads, and plastic threads according to their materials. In general, a thread is a thin strip-shaped straight line, and is incorporated into a part of the paper sheet as a straight line parallel to the transverse direction or the longitudinal direction.
- the optical sensor provided in the discriminating section is generally a line sensor, and is provided perpendicularly to the paper sheet transport direction. For this reason, the reading resolution of the sheet in the main scanning direction is fixed, but the reading resolution of the sheet in the sub-scanning direction is variable by controlling the conveying speed of the sheet. Also, as described above, since the thread is a fine line, the bill must be conveyed so that the optical sensor can scan the thread in the vertical direction, that is, the optical sensor can read the thread in the sub-scanning direction. Is desirable New

- the transport speed control means reduces the transport speed of the re-transported banknote from that at the first transport.
- the paper thread is usually swathed or woven into the paper. For this reason, if the thread position is parallel to the paper sheet transport direction, the thread may not be detected depending on the resolution of the sensor means in the main running direction.
- the paper sheet processing apparatus when the inserted paper sheet is discriminated from the counterfeit note, when the thread position of the paper sheet is parallel to the transport direction.
- the thread position is controlled so as to be re-transported in a direction perpendicular to the transport direction. Also, control is performed so that the transport speed is slowed down and the transport is performed again.
- the sensor means can acquire the image of the thread, and the discriminating means can more accurately discriminate the authenticity of the paper sheet discriminated from the previous counterfeit note by the presence or absence of the thread.
- the paper sheet processing apparatus is based on a paper sheet processing apparatus that discriminates inserted paper sheets. And discriminating means, determining means, The control means is provided.
- the discrimination means discriminates the authenticity of the inserted paper sheets.
- the determining means determines whether a counterfeit ticket has been inserted in one or more transactions based on the result of the discrimination by the discriminating means.
- the control means suspends the apparatus when the determination means determines that a counterfeit ticket has been inserted.
- the apparatus when a forged ticket is inserted in one or a plurality of transactions, the apparatus is stopped, so that a person in charge of the person who inserts the forged ticket can You can take some action.

Then, the determination result is stored in the storage unit 19. The dictionary comparing unit 17 also determines the presence or absence of a thread of the input paper sheet based on the dictionary data stored in the dictionary data unit 18.
- the dictionary data section 18 is used to determine the authenticity of various genuine bills created in advance by collecting image data of both vertical conveyance (vertical conveyance) and horizontal conveyance (horizontal conveyance) of various genuine bills. C These various genuine bills which store image data as dictionary data include genuine bills having threads.

If the thread is in a position parallel to the bill transport direction (as shown in Fig. 3 (a)), the inserted bill is returned to the slot once, and the bill is inserted in the bill direction (vertical and horizontal directions). A message prompting the user to change is displayed on the display (step S14). At this time, the customer may be notified by voice along with the message.
- the image processing unit 16 is inserted based on the reinserted image (an image obtained by normalizing the image read by the optical sensor unit 13 of the reinserted banknote). It is determined whether there is a thread of the bill (step S1). On the other hand, if the position of the thread is not parallel to the bill transport direction in step S13 (as shown in Fig. 3 (b)), the image processing unit 16 normalizes the bill (Fig. 2 (c)), the presence or absence of a thread of the bill is determined (step S16).
- the authenticity of the bill is first determined based on the normalized image of the bill. If the ticket is suspected to be a goose ticket, it is further determined whether or not the bill has been inserted in such a direction that the thread can be detected by the optical sensor unit 13, so that the thread cannot be detected by the optical sensor unit 13. If the banknote has been inserted in the direction, return the banknote to the slot, and prompt the customer to change the insertion direction and reinsert the banknote. As a result, for banknotes suspected to be goose tickets, the thread is reliably detected by the optical sensor unit 13 to determine the presence or absence of the thread. The authenticity of the inserted bill can be reliably determined.
