DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a product comprising a barcode scanner for reading a barcode attached to a product, and a sales registration terminal for performing sales registration processing of the product based on the barcode data from the barcode scanner. Related to sales registration device.

[0002]

2. Description of the Related Art For example, as shown in FIG. 4, a UPC system bar code has a configuration in which a left half segment and a right half segment are arranged between a left and right guard bar a and b with a center bar c interposed therebetween. When reading this barcode with a barcode scanner, data is read in half-segment units, and the data is combined later. X indicates an individual segment (for example, a combination of two white and black bars).

[0003] A two-stage barcode in which barcodes in half-segment units are combined in two rows is composed of a total of four half-segment data as shown in FIG. In a two-stage bar code, multi-stage bar code flags d1, d2 are arranged before guard bars a1, a2 at the end of the left half segment.

When the two-stage barcode is read by a barcode scanner, two-stage barcode data is obtained by combining four half-segment data obtained. In this case, the multi-stage bar code flag d1,
The left half segment or the right half segment is determined based on d2, and a combination in which the modulus 10 of the left half segment and the modulus of the right half segment match each other is searched by the sum check to obtain bar code data of each row. The checksum calculation of the half segment is, for example, (X6 + X4 + X2) +
{(X5 + X3 + X1) × 3} is performed, and the first digit of the result is used as the checksum value. Then, the sum value of the left half segment and the sum value of the right half segment are added, and when the first digit of the result becomes 0, a combination in which the modulus 10 matches is obtained.

[0005]

However, in the two-stage bar code shown in FIG. 5, even if the right half segment of the first stage and the right half segment of the second stage are interchanged in the combination of the read half-segment data, for example. If the modulus 10 of each bar code is the same, the correct combination cannot be determined.
Although the barcode was read, the barcode was determined to be an indeterminate barcode, and the data was discarded without being transmitted to the sales registration terminal.

For this reason, the operator has to enter data corresponding to the barcode with the keyboard at the sales registration terminal, which is troublesome, and the work efficiency of the registration work is reduced during this time.

[0007] Therefore, the present invention is capable of transmitting an undefined barcode to a sales registration terminal without discarding it even if the barcode data is generated. An object of the present invention is to provide a merchandise sales registration device capable of performing a registration process based on a product.

[0008]

According to the present invention, there is provided a bar code scanner for reading a bar code attached to a product, and a sales registration terminal for performing a sales registration process of the product based on bar code data from the bar code scanner. In the merchandise sales registration device, a bar code scanner is configured to display a bar code composed of a combination of left and right half segment data in front of a guard bar at the tip of the left half segment.
A multi-stage barcode flag to distinguish the barcode of each stage
When I read the two-stage bar code arranged in up and down are given, this
Determining whether the two-stage barcodes are of the same type and the checksum of the half-segment on the same side is the same, and the determining unit determines whether the two-stage barcodes are of the same type and the same half-segment Notification means for performing a notification operation when it is determined that the checksums are the same,
When the judging means judges that the two-stage barcodes are of the same type and the checksum of the same half-segment is the same, a message indicating that the combination of the left and right half-segment data of the barcode cannot be determined is attached to the bar. Transmission means for transmitting the code data to the sales registration terminal is provided. The sales registration terminal includes a message indicating that the combination received from the barcode scanner cannot be determined and a display for displaying the barcode data, and a specific key operation.
Depending on the operation, the combination of the left and right half-segment data of the two-stage barcode
Correction means for correcting the data.

[0009]

According to the present invention having such a configuration, when the bar code scanner determines by the determination means that at least two rows of bar codes are of the same type and the checksum of the half segment on the same side is the same, the notification is made. The barcode data is transmitted to the sales registration terminal with a message indicating that the operation is performed and the combination of the left and right half segment data cannot be determined.
Then, the sales registration terminal displays the received data on the display. The correction means corrects the combination of the left and right half segment data while checking the display contents. As a result, the barcode data becomes correct, and the sales registration process of the product is performed based on the barcode data.

[0010]

Embodiments of the present invention will be described below with reference to the drawings. In FIG. 1, 1 is a barcode scanner, and 2 is a sales registration terminal.

The sales registration terminal 2 includes a CPU (Central Processing Unit) 3 constituting a control unit main body, and an RO storing program data for the CPU 3 to control each unit.
M (read only memory) 4, RAM (random access memory) 5 provided with various memories for data processing, external interface 6 connected to the bar code scanner 1, host computer as a host device A connected external interface 7, a keyboard controller 9 for controlling a keyboard 8 to capture key signals, a display controller 11 for controlling a display 10 to display data, and a printer 12 for printing data on receipts and journals. An I / O port 16 to which a drawer opening device 15 for opening the printer controller 13 and the drawer 14 for opening the drawer 14 are connected.

The CPU 3, the ROM 4, the RAM 5, the external interfaces 6, 7, the controllers 9, 11,
The bus 13 and the I / O port 16 are electrically connected to each other.

The bar code scanner 1 is provided with a microprocessor, a memory unit, an LED (light emitting diode), a buzzer, and the like as notification means therein, and the control shown in FIG. 2 is performed by the microprocessor.

That is, when a two-stage barcode as shown in FIG. 5 is read, the barcode data of each stage is set in the memory unit. Then, it is determined whether or not the read barcode data is uncertain, that is, whether or not the barcode data is an uncertain label.

First, it is checked whether the data type of the first-stage bar code is the same as the data type of the second-stage bar code. If the data types are the same, it is checked whether the type is UPC-E.
Then, if it is not a UPC-E system, it is checked whether the checksum value of the left half segment of the first stage is the same as the checksum value of the left half segment of the second stage.
(Judgment means)

At this point, the fact that the checksum value of the left half segment of the first stage is equal to the checksum value of the left half segment of the second stage means that the modulus 10 of the left half segment of the first stage matches the right half segment. If there is a half-segment, the modulus 10 of the other right half-segment also matches the modulus of the second half-left half-segment, and is determined as an uncertain label.

When an uncertain label is determined, an LED is turned on and a buzzer sounds to notify the operator. In addition, data X indicating that the label is an uncertain label is transmitted to the sales registration terminal 2, and subsequently read two-stage barcode data is also transmitted to the sales registration terminal 2.

If the data type of the first-stage barcode is different from the data type of the second-stage barcode, it cannot be an uncertain label, so the read two-stage barcode data is immediately sent to the sales registration terminal 2. Send to Also UP
Since the CE system does not have the concept of a half-segment and cannot be an uncertain label, when it is determined that the system is the UPC-E system, the read two-stage barcode data is immediately transmitted to the sales registration terminal 2. I do. Further, even when the checksum value of the left half segment of the first stage and the checksum value of the left half segment of the second stage are different, the label cannot be an uncertain label. Send to 2.

When the sales registration terminal 2 receives the data from the barcode scanner 1, it displays the data on the display 10. Then, the control shown in FIG. 3 is started. First, it is determined whether or not data X is included in the data, and whether or not the data is an uncertain label. When it is determined that the label is an uncertain label, an uncertain correction key is initialized. This allows, for example, a key normally used for registration work or the like on the keyboard 8 to be exclusively used as a temporary uncertain correction key.

When the indeterminate correction key is turned on, the right half segment of the first row and the right half segment of the second row are exchanged. Further, when the next data is received from the barcode scanner 1 or when there is an operation of a key other than the uncertain correction key, for example, a registration closing key, the exclusive use of the uncertain correction key is released.

In this embodiment having such a configuration, when the barcode scanner 1 reads a two-stage barcode from a label, it checks whether or not the two-stage barcode is uncertain. When the data type of the bar code in the first row is different from the data type of the bar code in the second row, or when the UPC-
When the E-system is determined or when the checksum value of the left half segment of the first stage is different from the checksum value of the left half segment of the second stage, the read two-stage barcode data is immediately transmitted to the sales registration terminal 2. Send. Then, the sales registration terminal 2 performs registration processing of the merchandise sales data based on the received barcode data.

Also, the data type of the first-stage bar code of the read second-stage bar code and the data type of the second-stage bar code are not UPC-E, and the left half segment of the first stage is checked. When the sum value and the checksum value of the left half segment of the second stage are the same, it is determined that the label is an indefinite label, and the operator is notified by an LED and a buzzer. The data X indicating that the label is an uncertain label and the read two-stage barcode data are transmitted to the sales registration terminal 2. The data X received at the sales registration terminal 2
And the two-stage barcode data are displayed on the display 10.
Also, an indeterminate correction key is set.

Here, the operator determines whether or not the bar code data has been replaced on the screen of the display 18. If so, the indeterminate correction key is turned on to exchange the right half segment of the first row and the right half segment of the second row to correct the barcode data of the second row to correct data. Thus, the registration processing of the merchandise sales data is performed based on the correct barcode data.

When the next bar code reading operation by the bar code scanner 1 is started, the exclusive use of the uncertain correction key is released. In addition, even if a registration closing key operation or the like is performed on the keyboard 8, the exclusive use of the indeterminate correction key is released.

As described above, even if the uncertain label is determined, the barcode scanner 1 can be used without discarding the data.
Is transmitted to the sales registration terminal 2 and the sales registration terminal 2 uses the display 10 to determine whether or not the operator has replaced the half segments. If the replacement has been performed, the operator only operates the indeterminate correction key to replace the half segments. Can be corrected to normal bar code data, so that no operation is troublesome. That is, registration processing of merchandise sales data based on correct barcode data can be performed by a simple operation. Therefore, the work efficiency of the registration work does not decrease.
