[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a reading device and a processing terminal device, and more particularly to a device having a judging function for judging the accuracy of a code and a memory function having information for correcting an erroneously read result. -Data processing system.

[0002]

2. Description of the Related Art A conventional data processing system is disclosed in Japanese Patent Laid-Open No.
As in Japanese Patent Laid-Open No. 155594, it is detected whether or not the signal amplitude amount of an analog signal including a binarized code signal is a specific threshold value or more, and it is shown that the signal amplitude amount is a threshold value or less. When the same bar code was read a plurality of times during the reading, the reading was successful and the reliability and operability were improved.

The bar code is JIS X 0501.
However, as described in "POS General Inspection" (edited by Nihon Keizai Shimbun), pp. 168-173, the bar code
There are many problems with the quality of the input data itself such as code,
For example, if the print quality of the bar code is poor, or if the bar code is printed on the matching part or the wrinkled part of the packaging, the bar code cannot be read by the scanner, and it is read multiple times until the scanner reads it. (Rescan) method was used.

[0004]

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention
Since an attempt was made to improve the reliability and operability of reading the bar code only by the scanner, there was no transmission to the next device, and the processing load of the operator (checker) was high. Also, due to the bar code rescan, shoppers had to wait longer in the checkout lane, and there was concern that they might be charged a double amount of money from double reading. .

The present invention has been made in view of the above, and an object thereof is to suppress the rescan of the bar code to reduce the processing load of the operator and improve the productivity. The purpose of the present invention is to provide a data processing system capable of improving service such as relief of shopper's anxiety.

Another object of the present invention is to obtain a bar code having a bad print quality, such as a bar code which does not meet the bar code standard, and which is erroneously read.
An object of the present invention is to provide a data processing system capable of improving the bar code itself by communicating the code with the manufacturer.

Still another object of the present invention is to improve the checkout process to reduce the waiting time in the checkout lane and eliminate the anxiety of the shopper for the double amount bill coming from double reading. It is an object of the present invention to provide a data processing system capable of achieving the above.

[0008]

In order to achieve the above object, in the present invention, the data processing system is used to determine whether or not the bar code added to the product conforms to the standard. And the bar code that read the judgment result.
A scanner composed of a code generation unit for generating data together with the code data of the code, an input unit for receiving the data sent from the scanner, and a code unit corresponding to the code data. PLU (price l) with information such as product name and price
unknown data file consisting of an erroneous read code read by a scanner by mistake and an original code section corresponding to this erroneous read code and originally indicated by the barcode. The original code of the original code section corresponding to the misreading code section in the unknown data file and the storage section for storing and output the code data in the unknown data file. When there is no misreading code, the code code
The POS terminal device comprises a control unit for registering the data as an erroneous reading code in the erroneous reading code unit and for registering the information obtained by manual input as the original code in the original code unit.

[0009]

In the structure of the data processing system of the present invention described above, when the scanner reads a bar code or the like, the accuracy is judged by the judging section and the judgment result is the code code.
The data is generated together with the data by the data generation unit.

Then, the POS terminal device receives the data sent from the scanner through the input unit, and stores the information when the result indicating that the information of the data is not in the PLU file and is read incorrectly is added. Retrieving unknown data files in the department, responding to misreading codes, outputting the original code that the bar code should actually represent, and searching the PLU file to output the product name, price, etc. .

[0011]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the data processing system according to the present invention will be described in detail below from the scanner side and the POS terminal side with reference to the drawings.

FIG. 1 is a block diagram of an embodiment of a scanner according to the present invention.

In FIG. 1, 1 is a product, 2 is a bar code on the product, 3 is an article detector, 4 is a reading surface, 5 is a reading window, 6 is a scanning system, 7 is a laser, 8 is a photoelectric converter,
Reference numeral 9 is a bar code determination circuit, 91 is a determination unit, and 92 is a data generation unit.

FIG. 2 shows an example of the bar code 2 shown in FIG.
Represents the output data from the scanner according to the present invention. In FIG. 3, 10 is a code identifier part, 11 is a read result part, and 12 is a code data part.

An embodiment of the present invention on the scanner side will be described in detail below with reference to FIGS. 1 to 4 and 8.

When the article 1 passes over the reading surface 4, the article detector 3 senses the article 1 and the laser beam from the laser 7 starts scanning by the scanning system 6. When the commodity 1 passes through the reading window 5, the laser beam is incident on the barcode 2 attached to the commodity 1, and the light corresponding to the black and white level is reflected to the photoelectric converter 8. The photoelectric converter 8 converts the reflected light into an electric signal by photoelectric conversion and further converts it into a pulse signal. The bar code determination circuit 9 determines the width and interval of the bar from the width and frequency of this pulse signal,
The corresponding number is determined by the combination.

Here, when the result obtained from the pulse signal is encoded in a state where the print quality of the bar code 2 itself is poor and the print is blurred, the standard of the bar code 2 is determined. Therefore, it is not always converted into accurate code data. Considering such a situation, the determination unit 9
Reference numeral 1 determines whether or not the width and interval of the bar code 2 conform to an accurate standard, and the data generation unit 92 receives the determination result, and the data generation unit 92 reads the code code read from the bar code 2. Along with the data, the values indicating correctness and inaccuracy obtained by the determination unit 91 are added to generate and output the data.

FIG. 3 shows the data output from the scanner shown in FIG.
An example of data is shown below. This data has a code identifier portion 10 and a read result portion 11 each having 1 byte, and a code data portion 12
Consists of up to 13 digits. The code identifier section 10 is
For example, EAN-13, EAN-8, UPC-A, JAN
The read result section 11 indicates that the code is -13, etc., and the read result section 11 gives a value of 0 when the code is exactly in conformity with the standard. ,
When the code is out of the standard, a value of 1 is shown. The code data section 12 shows the actual data (numerical value here),
13 digits for EAN-13, 8 digits for EAN-8, UPC-A
Indicates 12-digit code data, and JAN-13 indicates 13-digit code data.

As will be described later, by generating such data, particularly by adding the read result section 11, in the processing of the next device which receives the data,
It can be processed mechanically without human intervention. This is because if a code that does not conform to the standard is simply read as an error as in the conventional case, the trouble of manually inputting a 13-digit product code will occur. is there.

FIG. 4 is a diagram showing one specific example of the bar code 2 itself, an electric signal obtained by converting the bar code 2 and a pulse signal, and a pulse signal showing three types of data.

For example, under an accurate standard, a is a numerical value "
4 "and b represents the numerical value" 5 ". Here, when the pulse signal of c is obtained as a result of reading the bar code 2 printed on the product 1, the result of FIG. The judging section 91 and the data generating section 92 judge the bar code 2 and generate the data shown in FIG. 3, and at that time, one method of the judgment in the judging section 91 is as shown in FIG. It is assumed that the determination is made based on the ratio of ACs among ABs, and this is shown in Table 1 in correspondence with the read result section 11 and the code data section 12 of FIG. Since the ratio occupied by AC is 35%, the reading result 11 of FIG.
Is a value "1" that indicates an incorrect reading, code data unit 1
2 creates data with the value "4".

[0022]

[Table 1]

Further, as another example shown in FIG. 3, as a detailed content of the state of being out of the standard as shown in FIG.
Is a code that exactly conforms to the standard, the value 1 is classified so that the black bar is too thick, the value 2 is too far to the right, and the value 3 is lightly printed. This is a result of reading the portion corresponding to each byte of the code data portion 12
In the examples shown in FIGS. 1A and 1B, it is possible to determine the condition of reading each digit of the code data unit 12 by the numerical value of the read result unit 11.

The above example is an example of the reading device for reading the bar code printed on the paper, but it is not the data output on the paper but the data recording medium such as a card, that is, a magnetic card or an optical card. The same can be said for a device that reads the data.

A specific embodiment of the present invention on the POS side will be described in detail below with reference to FIGS. 5 to 11.

FIG. 5 is a block diagram of a POS terminal device according to the present invention. In FIG. 5, 13 is an input unit, 14 is a display unit, 15 is a control unit, 16 is a warning unit, 17 is a storage unit,
Reference numeral 18 indicates a PLU file, and 19 indicates an unknown data file. The PLU file 18 is an area in which a plurality of data including a product code, a product name, a price, etc. is registered, and the unknown data file 19 is erroneously read as a product code attached to an input product. This is an area for registering time data.

FIG. 6 is an example showing the details of the unknown data file 19 of FIG. In FIG. 6, 20 is a misread code section, 21 is a frequency section, and 22 is an original code section. Here, the misread code section 20 and the original code section 22 are distinguished as follows. The product code attached to product 1 is 49
Although it was 12345678904, the print quality was poor, and it was assumed that the scanner read 4912345078904 (however, there is no check digit in this description). At this time, the misread code section 20 is 4912345.
It is 078904, and originally the code section 22 is 4912345678904 actually attached to the product.

FIG. 7 is a flow chart of the processing in the control section 15 of FIG. 5, which is shown together with the operation of the operator (checker).

The operation will be described below with reference to the flowchart of FIG.

FIG. 3 read by the scanner of FIG.
Is sent to the input unit 13 (S1), and the control unit 15 uses the PL in the storage unit 17 based on the input data.
Search U file 18 (S2), PLU file 1
It is checked whether or not it exists in S8 (S3). If it exists, the process proceeds to S4, and if it does not exist, the process proceeds to S5.

In S4, the product name, price, and other data obtained by searching the PLU file 18 are displayed on the display unit 14 and printed from the print unit (S4), and the process is terminated.

In S5, it is determined whether or not the determination result can be accurately determined based on the value of the read result portion 11 among the fetched data of FIG. 3 (S5). When it shows an incorrect determination value, the process proceeds to S8.

Here, a few words will be described regarding the order of the processes of S3 and S5. PLU only when the result can be accurately determined
There may be an idea that the file 18 should be searched, but the bar code 2 of the product 1 usually has poor print quality and is out of the standard bar code. There are many things that are present, and if such things are processed so as to ask the operator to make a decision, the operator's confirmation work becomes troublesome. Some data can be uniquely interpreted even if they are out of the standard. If such data is found by searching the PLU file 18, if it exists, it is processed as if it was correctly read and converted. Once done, the operator confirmation work is greatly reduced. In consideration of these points, the PLU file 18 is searched in this embodiment.

In S6, the warning section 16 issues a warning that the input data is not registered in the PLU file 18 (S6). Then, the operator inputs the input data to the PLU file 18 by the warning. Because I know that it is not registered, the number attached to the bar code or
By manually inputting the price, the price is printed from the display unit 14 and the print unit (S7), and the process is terminated.

At this time, the data manually input by the operator may be automatically registered in the PLU file 18.

At S8, as described above, the data which does not exist in the PLU file 17 and which is input by the determination at S5 is input.
Since the data comes in when it is not correct (so-called non-standard code), the control unit 15 searches the unknown data file 19 from this data (S8), and the unknown data file 1
9 is checked (S9), and if present, the process proceeds to S10, and if not present, the process proceeds to S12.

In S10, it is the case that the file exists in the unknown data file 19, and the count section 21 corresponding to the misread code section 20 in the unknown data file 19 is counted up (S10). The PLU file 18 is searched by the original code section 22 corresponding to the section 20 (S11), the process proceeds to S4, and the data such as the product name and the price obtained by searching the PLU file 18 is displayed on the display section 1.
Printing is performed from the display / printing unit from step 4 (S4), and the process ends.

In S12, it is the case that the input data does not exist in the unknown data file 19, and the data is
Data in the unknown data file 19. As the registration processing, the code of the bar code 2 read by the scanner is input to the misreading code section 20, and the count section 21 is set to 1 since it occurred for the first time. 22 is initialized and registered (S12). Then, the code read by the scanner is displayed on the display unit 14, and the warning unit 16 issues a warning that the determination cannot be made correctly (S13).
By drawing the attention of the operator, the operator manually inputs the numerical value attached to the bar code 2 (S14), and the manually input numerical data is used as the original code part of the unknown data file 19. 22. The original code part 22 is searched for the PLU file 18 (S15).
Perform the following processing.

In S12, if there is data that could not be accurately determined once, it is acquired as unknown data in the unknown data file 19. However, even if the data is acquired when the number of times is equal to or more than the specified number of times. Good.

In the above embodiment, as the unknown data file 19 as shown in FIG. 6, the misread code section 20 and the number of times section 2 are used.
1 and the code section 22 originally, but other examples are possible. For example, as shown in FIG. 9, only the misread code section 20 and the original code section 22 are included in the unknown data file 19 and the number of times section 2
It does not need to have 1 and may not count the number of times. At this time, in the process of FIG. 7, the number of processes in S10 and S12 is not performed.

Further, as shown in FIG. 10, the unknown data file 19
As an example, only the misread code section 20 may be used, and the misread code may be sequentially registered. FIG. 11 shows an example in which the unknown data file 19 has the read result section 11 indicating the detailed contents of each digit as an area as described in FIG. In the case of FIGS. 10 and 11, S10 in the processing of FIG.
The processing from S15 to S15 is automatically registered only in the misread code section 20 or the misread code section 20 and the read result section 11 in the unknown data file 19, and the warning section 16 for the original code. It may be changed to a process of inputting each time by the operator according to a notification method such as a warning from the display or a display from the display unit 14. Then, the process can be completed by searching the PLU file 18 with the manually input data.
The contents registered in the unknown data file 19 will be confirmed later.

In the above embodiments, the bar code was taken as an example for explanation, but the present invention is not limited to other recording media (optical card).
Needless to say, the present invention can also be applied to magnetic cards, magnetic cards, etc.).
