Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention comprises a bar code scanner for reading a bar code attached to a product, and a sales registration terminal for performing a sales registration process for the product based on the bar code data from the bar code scanner. Sales registration device.

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

A two-stage bar code in which two columns of such half segment bar codes are combined is composed of a total of four half segment data as shown in FIG. In the two-stage bar code, multi-stage bar code flags d1 and d2 are arranged in front of the guard bars a1 and a2 at the tip of the left half segment.

Then, when the two-stage bar code is read by a bar code scanner, four half segment data obtained are combined to obtain the two-stage bar code data. In this case, the multi-stage bar code flag d1,
The left half segment or the right half segment is judged from d2, and the combination in which the modulus 10 of the left half segment and the right half segment are matched is searched by the sum check to make the bar code data of each stage. The checksum calculation of the half segment is, for example, (X6 + X4 + X2) + in the case of the half segment of FIG.
{(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, the modulus 10 is matched.

[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 exchanged in the combination of the read half segment data, for example. When the modulus 10 of the bar code of each stage is the same, it is impossible to judge the correct combination.
Despite reading the barcode, it was judged as an indeterminate barcode and the data was discarded without being sent to the sales registration terminal.

Therefore, in the sales registration terminal, the operator has to input the data corresponding to the bar code by using the keyboard, and there is a problem that the work efficiency of the registration work decreases during this period.

Therefore, according to the present invention, even if an indefinite bar code is generated, it can be transmitted to the sales registration terminal without discarding it. In the sales registration terminal, the indefinite bar code is corrected by a simple operation to modify the bar code data. An object of the present invention is to provide a merchandise sales registration device that can perform registration processing based on

[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 product sales registration process based on the bar code data from the bar code scanner. In the product sales registration device, when a multi-stage barcode consisting of a combination of left and right half-segment data in multiple rows is read, the barcode scanner has at least two rows of the same type. And a determining means for determining whether or not the checksums of the half segments on the same side are the same, and this determining means determines that the barcodes of at least two columns are the same type and the checksums of the same half segments are the same. The notification means for performing the notification operation and the determination means have the same bar code in at least two rows. When the checksums of the same half segment are the same and the checksums of the same half segment are the same, a sending means for sending the barcode data to the sales registration terminal with a message indicating that the combination of the left and right half segment data of the barcode cannot be confirmed The sales registration terminal is
It is provided with a display that displays a message and bar code data indicating that the combination received from the bar code scanner cannot be confirmed, and correction means that corrects the combination of the left and right half segment data of the bar code data. is there.

[0009]

In the present invention having such a structure, when the bar code scanner judges that the bar codes of at least two rows are the same type and the checksums of the half segments on the same side are the same, the notification is given. The bar code 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. Then, while confirming the display contents, the correction means corrects the combination of the left and right half segment data. As a result, correct bar code data is obtained, and the sale registration process of the product is performed based on this bar code 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 which constitutes a main body of a control unit, and an RO which stores program data for the CPU 3 to control each unit.
An M (read only memory) 4, a RAM (random access memory) 5 provided with various memories for data processing, an external interface 6 connected to the barcode scanner 1, a host computer as a host device The external interface 7 connected, the keyboard controller 9 that controls the keyboard 8 to capture key signals, the display controller 11 that controls the display 10 to display data, and the printer 12 to print data on receipts and journals. An I / O port 16 to which a printer controller 13 for opening the drawer 14 and a drawer opening device 15 for opening the drawer 14 are connected are provided.

The CPU 3, the ROM 4, the RAM 5, the external interfaces 6 and 7, the controllers 9 and 11,
13 and the I / O port 16 are electrically connected by a bus line 17.

The bar code scanner 1 is internally provided with a microprocessor, a memory section, an LED (light emitting diode) as a notification means, a buzzer, etc., and the microprocessor performs the control shown in FIG.

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

First, it is checked whether the data type of the first-stage bar code and the data type of the second-stage bar code are the same. If the two data types are the same, then it is checked whether the types are UPC-E.
If it is not the UPC-E system, then it is checked whether or not 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 the same.
(Determination means)

At this time, 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 the same, which means that the modulus 10 of the left half segment of the first stage is the same. If there is a half segment, the modulus 10 of the other right half segment and the left half segment of the second stage also match, and it is determined as an indefinite label.

When the uncertain label is judged, the LED is turned on and the buzzer is sounded to notify the operator. Further, the data X notifying that the label is an indefinite label is transmitted to the sales registration terminal 2, and the subsequently read two-stage bar code data is also transmitted to the sales registration terminal 2.

If the data type of the first-stage bar code is different from the data type of the second-stage bar code, it cannot be an indeterminate label. Therefore, the read second-stage bar code data is immediately transferred to the sales registration terminal 2 Send to. UP
Since the CE system does not have the concept of a half segment and cannot be an indefinite label, when it is determined to be the UPC-E system, the read two-stage bar code data is immediately transmitted to the sales registration terminal 2. To do. Furthermore, even if the checksum value of the left half segment of the first step and the checksum value of the left half segment of the second step are different, it cannot become an indeterminate label, so the read two-step bar code data is immediately sent to the sales registration terminal. Send to 2.

When the sales registration terminal 2 receives the data from the bar code scanner 1, the sales registration terminal 2 displays the data on the display 10. Then, the control shown in FIG. 3 is started. First, it is judged whether or not the data X is included in the data, and then it is judged whether or not it is an indefinite label. When it is determined that the label is the indeterminate label, the indeterminate correction key is initialized. For this purpose, a key normally used for registration work on the keyboard 8 is exclusively used as a temporary uncertain correction key.

When the indetermination correction key is turned on, the first-stage right half segment and the second-stage right half segment are switched. Further, when the next data is received from the bar code scanner 1 or the operation of a key other than the indetermination correction key, for example, a closing key for registration or the like, the exclusiveness of the indetermination correction key is released.

In this embodiment having such a configuration, when the bar code scanner 1 reads a two-stage bar code from a label, it is checked whether or not the two-stage bar code is indefinite. If the data type of the first bar code and the data type of the second bar code are different, UPC-
When it is judged to be the E system or when the checksum value of the left half segment of the first step and the checksum value of the left half segment of the second step are different, the read two-step bar code data is immediately sent to the sales registration terminal 2. Send. Then, the sales registration terminal 2 performs registration processing of the product sales data based on the received bar code data.

Also, the data type of the first-stage bar code of the read second-stage bar code is the same as the data type of the second-stage bar code, and it is not the UPC-E system, 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 row are the same, it is determined that the label is an indefinite label, and the LED and buzzer inform the operator. Further, the data X indicating the indefinite label and the read two-stage bar code data are transmitted to the sales registration terminal 2. The data X received at the sales registration terminal 2
And the two-stage bar code data are displayed on the display unit 10.
Also, set the indeterminate correction key.

Here, the operator determines whether the bar code data has been exchanged on the screen of the display unit 18. If they have been replaced, the uncertain correction key is turned on to replace the right half segment of the first row with the right half segment of the second row and correct the barcode data of the second row to correct data. In this way, the registration process of the product 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, monopolization of the indeterminate correction key is released. Further, even if the closing key operation for registration is performed on the keyboard 8, the monopolization of the indetermination correction key is released.

As described above, the barcode scanner 1 does not discard the data even if the indeterminate label is judged.
From the sales registration terminal 2, and the sales registration terminal 2 determines whether the operator has replaced the half segment with the display 10 and, if so, replaces the half segment simply by operating the uncertain correction key. Since it can be corrected to normal bar code data, there is no need for troublesome work. That is, it is possible to register the product sales data based on the correct barcode data with a simple operation. Therefore, the work efficiency of the registration work does not decrease.

Although the above embodiment has described the case of the two-stage bar code as the other-stage bar code, the present invention is not limited to this, and the bar code having three or more stages may be used.

[0027]

As described above in detail, according to the present invention, even if an indeterminate bar code is generated, it can be transmitted to the sales registration terminal without discarding it, and the indefinite bar code can be easily transmitted to the sales registration terminal. It is possible to provide a merchandise sales registration device that can be modified by various operations to perform registration processing based on barcode data.
