Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a paper sheet processing device that processes paper sheets while identifying abnormally mixed sheets.

Conventionally, there is a method for identifying paper sheets that are in abnormal positions (front and back, upside down), and paper sheets of different types as so-called abnormal paper sheets, such as those used in vending machines. There is a method of temporarily stopping fully inserted banknotes midway through the process, detecting and identifying the banknotes at that stop position, and then accepting the banknotes.Also, there is a method of placing banknotes on the conveyance path, as is done with a banknote identification and counting machine. There is a method of detecting and determining based on the detected detection unit.

However, with these methods, it is not possible to increase the processing speed when the paper is temporarily stopped, and when the paper is detected by reflected light or transmitted light from the surface of the paper while it is being conveyed, the paper is scanned at high speed. Therefore, in order to improve the discrimination accuracy, it is necessary to increase the density of the scanning lines, which makes the device expensive.

In a device intended by the present invention, for example, a paper sheet counting and processing device that places a bundle of separated paper sheets in a supply section and sends seven sheets at a time from this supply section to a stacking section for counting, the number of paper sheets is Since a large number of bundles must be processed, it is desirable not only to shorten the time required to detect and discriminate abnormal sheets, but also to improve the discrimination accuracy by an inexpensive method.

This invention has been made in consideration of the above point Kg, and detects and discriminates abnormal paper sheets in a stationary state before the start of supply from the supply section or in a stationary state after being carried into the stacking section. It is an object of the present invention to provide a paper sheet processing device that does not impose restrictions on the processing speed of leaves and improves the discrimination accuracy.

Hereinafter, one embodiment of the present invention will be explained based on the drawings. Figure 0 shows, for example, a paper-sheet counting device as a sheet processing device, and only the abnormal sheet discrimination circuit portion is shown, and the counting circuit The parts are not shown, and the symbol / indicates a bundle of nine sheets placed in either the supply section or the stacking section, but here we will explain the one in which the abnormality determination is performed on the stacking section side. The light source part 3 is sequentially carried in and stacked and placed facing the surface of the filter paper, and the light receiving part 3 receives the reflected light from the six paper leaf surfaces that illuminates one or more moss parts on the paper leaf surface. The 0 discriminator 5 transmits signals indicating the amount of light received, the wavelength, and their distribution, and after the signals are amplified and shaped by the AD converter da, they are sent to the discriminator j. By comparing the signal from the paper sheet condition storage unit 6 and the signal from the AD converter Hiroshi, the type of paper sheet, front and back sides,
Determine the top and bottom (top and bottom). The control section 7 receives the discrimination signal from the discriminating section j, and when the abnormal paper sheet is carried into the stacking section, the control section 7 stops the conveyance of the paper sheet from the supply section to the stacking section by using the transport button 1811 section 7a. The alarm control section 7bK issues an alarm.

As described above, the different types of paper sheets and the posture of the paper sheets carried into the stacking section are determined. If the paper is distributed in such a way that it is possible to determine whether the paper is abnormal at the position where it is about to be sent out, the paper can be inspected at the stacking section or the supply section, thereby detecting and determining abnormal paper sheets. The processing time can be shortened and the discrimination accuracy can be improved, so that the paper sheet counting processing speed can be increased.
