Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for determining the authenticity of cash vouchers such as hand stamps and bills.

Recently, with the introduction of the non-impact printer tX, it has become possible to output names, addresses, etc. in kanji at high speed, which was previously impossible. However, when using a non-impact printer to print cash notes, etc., the printing with toner, etc., is not firmly fixed to the paper, so There is a drawback that important cash vouchers are easily tampered with. For this reason, conventionally,
Printing on cash vouchers with non-impact printers has been avoided.

This invention provides an apparatus for determining the authenticity of cash vouchers, which prints the amount, etc. on the cash vouchers using a non-inbound i-printer and reliably determines the authenticity when redeeming the cash vouchers even if the printing on the cash vouchers is forged. It is aimed at this.

This invention will be explained below.

In printing on cash vouchers in this invention, the data output by the non-impact printer is expressed in two ways: one is expressed in decimal numbers that can be recognized normally, and the other is expressed in decimal numbers that can be recognized normally. It is now displayed in a coded symbol that cannot be easily recognized by the second party or the recipient of the certificate. This encoded symbol is quickly and accurately read by the authenticity discrimination device of this invention, which is prepared at the checking place at the time of cash exchange, etc., and the check digit is calculated, and the arithmetic digit of lOa is calculated. It is now displayed as . Here, checking of cash vouchers is often performed at the time of exchanging for cash, and there is no need to store the check results in the authenticity determination device. Therefore, the authenticity determination device of the present invention does not have a memory for storing the check result, and after writing the check digit J1, the liquid crystal display
Lfl;D) is displayed and automatically disappears when the next data is input. As a result, a light, quick, and compact device for distinguishing between authenticity and falsity is realized.

The present invention will be explained in detail below with reference to the drawings.

Figure 1 shows an example of printed cash vouchers 3 that are the subject of this invention.The cash vouchers 3 distributed to recipients are printed with the name "Tokyo Tabe" and the recipient's name using a non-impact printer or the like. Barcode including code etc. 2. Benefit amount r I ,
270,000 yen J is printed on it. Here, especially for data that is thought to be misused by tampering with the printed content, a check digit I is added to the data and printed as a barcode 2. For example, if it is expected that the payment amount I of cash vouchers 3 will be tampered with, the check digit for the amount r 1,270,000 yen is calculated by 7-check OR and added after the least significant digit. In other words, “1,270,900÷7 = 18
1428...4'', so add the digits and convert it into a barcode as the amount "'1,270.0004" and display it as barcode 2. Barcode 2 can be printed with a thin impact printer, etc. For example, NW-7 is good for printing.In addition to 7-check OR, 7-check DSR,
9 check OR, 9 check DSR, 97 check, modulus 11. There are modulus lO, etc., and an arbitrary check digit can be selected by changing the output program in a non-impact printer or the like and the calculation program in the authenticity discriminating device described later. If such a check digit is included in the displayed amount of the benefit amount l, and this check digit is encoded into a barcode 2 and printed, a third party who picks up the cash vouchers 3 will have a copy.
I don't understand the contents of code 2 and the check digits. Therefore, even if a third party falsifies the payout (=J amount 1, etc.) of cash vouchers 3, it is not possible to recalculate the recheck digit obtained by adding 11 iE to barcode 2. The authenticity of the cash vouchers 3 can be determined by reading the barcode 2 printed on the card and comparing it with the benefit amount 1, or by checking the check digit.

Next, the Perco 1 printed on the cash vouchers 3 as described above.
An example of an authenticity discriminating device for reading ``2'' with a simple operation and determining μ° (forgeries) of cash notes 3 will be explained.

Figure 2 shows the external appearance of the authenticity discrimination device, and the overall structure is pen-shaped with a mirror body 5 that can easily scan the surface of the cash notes 3, and the display section and reading processing section. It has no external connection devices such as lead wires. That is, the display section is formed so that 7 segments are displayed on the -L part of the mirror body 5 through a transparent window 15 such as a crow, and the cash vouchers 3 are printed on the lower end of the mirror body 5. A lens 4 for optically reading data is provided, and a switch 10 provided in the middle of the mirror body 5 is held in the hand like a pen to read the data.
This is done by activating the built-in circuit by pressing with your index finger, etc. Moreover, FIG. 3 is a diagram showing the internal structure of the authenticity discrimination device, and FIG. 4 is a side view showing a partial cross section. Behind the lens 4, there is a A light emitting diode (LEI) 6 is disposed, and a fat transistor 7 for receiving light reflected from the scanning surface is disposed. A printed circuit board 14 is stretched in the middle of the mirror body 5, and a C-MO9 type LSI processing unit 8, which will be described later, is mounted on this printed circuit board 14, and an LCD 9 is mounted thereon. It is installed horizontally, exactly 1. Transparent windows 15 are located on both sides of the CD 9. Furthermore, the end a of the printed circuit board 14
++ is a micro battery (for example, a lithium battery) 11
The micro battery 11 is held between a battery holder 13 that also serves as an electrode and a battery box 512, and the battery 11 can be replaced by removing the battery box lid 12. .

FIG. 5 is a block diagram showing the internal configuration of the authenticity discriminating device, in which the LSI processing unit 8 controls the condition [: PU 18 and the performance T1. When writing data, etc.
It consists of a RAM 19 for reading, a BCD-7 segment decoder/driver 20 for displaying the LCD 9 in 7 segments, and an encoder 21 for converting the input J data into a ghost code. Then, the read data from the photoconverter/distaff R3 is amplified and waveform-shaped by the amplification/waveform-shaping circuit 16, then converted into digital data by the AD converter 17, and then manually input to the encoder 21. There is. Also, CPU18. RAAs2 decoder/driver 20 and encoder 21 are connected to data bus 2
2 and address/hess 23 to phase 7j,
Electric power from the micro-tube 11 is supplied to the processing unit 8 and the like via the switch 10.

In the configuration as described above, when the authenticity determination device is not used again, the switch 10 is turned off, power is not supplied to the circuit system, and the LED 8 does not emit light. When reading the 1 < - code 2 printed on the cash voucher 3 to determine its authenticity, first turn on the switch 10, which supplies power from the micro battery 11 to the circuit system, and the LED 6 lights up. The barcode 2 is illuminated by light through the lens 4. The strong and weak reflected light reflected by the barcode 2 passes through the lens 4 and is input to the phototransistor, and the read signal R3 from the phototransistor 7 is amplified and shaped by the amplification-waveform shaping circuit 16 and then sent to the ADf converter. 17
The converted digital +-4 is input to the processing unit 8.

The processing unit 8 temporally measures the pa part and the space part of the barcode 2, calculates the check digital weight or the check weight using the arithmetic method written in advance in the RAM 19, and uses the CPU 1B to calculate the : Determine whether or not the a value is an error. Then, the decoder 2/driver 20 of the F3CD-7 segment displays the IO base number on the LCD 8.

L Ct) 9 is located inside the mirror body 5, and the display is read through the transparent window 15. In this case, if there is a discrepancy between the check digit calculation result by the processing unit 8 and the actual check digit, rEJ indicating an error is displayed in the small digit of the LCD 9. If this error message is displayed, as long as there is no error in the printing of barcode 2 on vouchers 3 and \.

It can be determined that forgery has occurred.

(-6) As a way to increase the effectiveness of preventing counterfeiting of cash vouchers by using an authentication device as described in 6, the width and space of the par 1-'-1' should be minimized as much as possible to print and read it. It is sufficient to reduce the width and use complex modulus 11 as the check digital.
I am using CMOS (use 1) to keep power consumption low, LED and LCD" (9) consume a lot of power, so even after pressing the switch and displaying the operation, the next reading will not be taken even after 30 seconds have elapsed. If this is not done, the power supply is automatically turned off.As a result, if a lithium battery is used as the micro battery, it is not necessary to replace the battery for about a year with an average frequency of use.

In addition, in the above description, the coupons are printed using a non-impact printer, but the same applies even when printing is performed using an impact printer.
