Abstract

PROBLEM TO BE SOLVED: To save the labor of inputting through keys and prevent wrong printing by reading bar codes by a bar code scanner and calling information on commodities from the read bar codes. SOLUTION: A bar code scanner 6 automatically reads bar codes of labels and outputs bar code data to a microcomputer 1. The microcomputer 1 analyzes the bar code data and temporarily stores code information into a code memory part 14. The bar code data stored in the code memory part 14 and bar code data stored in a printing data memory part 13 before printing is carried out are compared with each other to check whether the bar code read by the bar code scanner 6 is a bar code to be printed by a printing part 2 or not. When the bar code is correctly printed, a commodity master 12 is read from commodity codes of the bar code data stored in the code memory part 14 and displayed to a touch screen 3.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bar code printing machine.

[0002]

2. Description of the Related Art A bar code printed by a bar code printing machine may lack a bar or become unclear due to various factors. In such a case, the bar code cannot be read later. In view of the above, there has been a bar code printing machine that reads a printed label with a bar code with a bar code scanner and checks the bar code (for example, Japanese Utility Model Publication No. 6-47738).

[0003]

However, in the above-mentioned prior art, when issuing a label, it is necessary for an operator to input information on a product. At this time, if the operator makes an error, an incorrect label is issued. In addition, when issuing, the key input is troublesome and the workability is low.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a bar code printer and a product processing apparatus provided with the bar code printer, in which the trouble of key input is eliminated and there is no risk of erroneous printing.

[0005]

According to a first aspect of the present invention, there is provided a bar code printing machine for reading a bar code with a bar code scanner and checking the bar code. The bar code is read by a code scanner, and information on the product can be called (read) from the read bar code.

When a label or a form on which a barcode is printed is at hand, the operator causes the barcode to be read by a barcode scanner. The CPU searches the memory based on the barcode, reads out information on the product from the memory, and causes the printer to print the barcode.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings. In FIG. 1, the bar code printing machine includes a printing unit 2, a touch screen 3, a stroke key unit 4, a weighing unit 5, and a bar code scanner 6 connected to a microcomputer 1 via an interface (not shown). The microcomputer 1 includes a CPU (calculation means) 10 and a memory 11.

The printing unit 2 includes a CPU 10 of the microcomputer 1.
In accordance with the print information and print command from the printer, predetermined print contents including a barcode are printed on a label or the like and issued. The touch screen 3 constitutes a display for displaying various screens, and can perform input by touching a part of the display screen with a finger. The stroke key unit 4 in FIG. 1 includes a numeric keypad, and is used for inputting numerical values and the like. The CPU 10 calculates the price of the product by multiplying the weight measured by the weighing unit 5 by the unit price of the product, and determines the print information of the product including the barcode.

The memory 11 is provided with a product master 12, a print data storage unit 13, and a code storage unit 14. As shown in FIG. 1B, the product master 12
Stores product information such as a product code, a product name, a section, and a unit price for each product.

The print data storage unit 13 has a configuration shown in FIG.
Print data to be printed on the label L as shown in (a) is temporarily stored. A bar code B is printed on the label L in addition to the product information. The information of the bar code B includes, for example, the price Pr of the product in addition to the product code Cm.

The bar code scanner 6 shown in FIG. 1 automatically reads the bar code B of the label L and outputs the bar code data to the microcomputer 1. The microcomputer 1 decodes the barcode data and temporarily stores code (numerical value) information in the code storage unit 14. For example, FIG.
In the case of the label L, the code “0225896003809” is stored in the code storage unit 14.

The CPU 10 has an issuing mode in which a bar code is printed by the printing unit 2, and a calling mode (an example of a non-issuing mode) in which product information is called from the bar code B printed on the label L in FIG. In the present embodiment, the issuing mode or the calling mode can be selected by performing a predetermined setting operation (manually). In the issue mode, C in FIG.
The PU 10 reads the bar code of the printed label and the bar code data read by the bar code scanner 6 from the print data storage unit 13 and the code storage unit 14 and checks them, so that a predetermined bar code is printed. Check if there is. The bar code check function and the like in the issuing mode are described in
No. 738, col. 4, line 39 to col. 8, line 8 describes an example in detail. On the other hand, in the calling mode, the CPU 10 stores the bar code data input from the bar code scanner 6 in the code storage unit 14, extracts a product code from the stored bar code data, and further, based on the extracted product code. The information of the product is called from the product master 12 shown in FIG. 1B, and the called product information is displayed on the touch screen 3.

Next, the CPU 10 of the bar code printing machine will be described.
Will be described with reference to the flowchart of FIG. When the present system starts, the barcode scanner 6 reads a barcode in step S1. The read barcode information is stored in the code storage unit 14 by the CPU 10, and the process proceeds to step S2. In step S2, the CPU 1
0 determines the current mode, and if it is set to the issue mode, the process proceeds to step S3, while if it is set to the non-issue mode such as the call mode, the process proceeds to step S10.

In step S3, the code storage unit 14
The barcode data stored (read by the barcode scanner 6) is compared with the barcode data stored in the print data storage unit 13 before printing. It is checked whether the bar code is to be printed by the printing unit 2, that is, whether the bar code is correctly printed. As a result of this check,
If the printing is correct, the process proceeds to step S4 to perform a predetermined normal process. If the printing is not correct, the process proceeds to step S11 to perform a predetermined abnormal process.

In step S10, that is, in the call mode, the CPU 10 reads the bar code data stored in the code storage unit 14, searches the product master 12 from the product code of the bar code data, and stores the information of the product. Read from product master 12, touch screen 3
To be displayed.

Next, the operation in the call mode will be described. First, the operator performs a predetermined operation to display a product calling screen on the touch screen 3 of FIG. 1 and sets the calling mode. Next, when a barcode such as a barcode label to be printed is read by the barcode scanner 6, information on the product is displayed on the screen. Thereafter, when a predetermined key operation is performed, a bar code and information on the product are printed on the label L by the printing unit 2.

As described above, in the present bar code printing machine, it is not necessary to input the product code and the call number by key operation when calling the product. There is no risk of printing codes or product information.

Incidentally, the label L to be printed in the present invention includes a label having product information as shown in FIG. 2B in addition to FIG. 2A. In the present invention,
The barcode B read by the barcode scanner 6 may be a barcode B (FIG. 2C) other than the barcode printed by the barcode printer itself.

In the above embodiment, the CPU 10 determines whether or not the bar code is printed from the printing unit 2 in step S2 in FIG. 3 according to the current mode of the CPU 10. May be determined based on whether or not predetermined information is included in the barcode data. That is, in the embodiment, the CPU 10 is set to the issue mode or the call mode by performing a predetermined setting operation in advance (although the switching between the issue mode and the call mode is manually performed). In the present invention, both modes may be switched by the CPU 10 determining (automatically) whether or not predetermined information is included in the barcode information.

For example, when the bar code is a bar code system such as JAN or ITF (when the bar code information includes predetermined information), or when the number of digits of the bar code is
If the number is 10 digits or 12 digits (when the barcode information includes predetermined information), the process proceeds to step S10, and the product information may be called from the product master 12 based on the barcode data. . Alternatively, the determination in step S2 may be performed based on a numerical value of a specific number of digits of the barcode data. For example, if the numerical value of the 10th digit of the barcode is “1” in step S2, the process proceeds to step S3 to check the barcode, while the numerical value of the 10th digit of the barcode is “2” in step S2. "
Proceeding to step S10, the information of the product may be read from the barcode.

It goes without saying that the present invention also includes a commodity processing apparatus provided with a packaging machine and a label pasting machine in a bar code printing machine. Also, there is no need to provide an electronic balance.

[0022]

As described above, according to the present invention,
Product information can be called up from the barcode read by the barcode scanner of the barcode printing machine.
This eliminates the need for key entry and eliminates the risk of printing incorrect barcodes or product information.
