DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic cash register (ECR) having a bar code reader,
The present invention relates to a merchandise sales data processing device such as an S (point of sales) terminal.

[0002]

2. Description of the Related Art Conventionally, there has been known a merchandise sales data processing apparatus having a bar code reader for optically reading a bar code attached to a merchandise and performing a merchandise registration process based on the bar code data. In such a product sales data processing apparatus, a barcode attached to a product is optically read by a barcode reader such as a touch scanner, and if the read barcode data is product data, R
The registration process is performed by updating the sales quantity, sales amount, etc. of the product file for each product code formed in the AM (memory).

[0003] In supermarkets and the like, the selling price of a product is frequently discounted after a certain time. This is especially true for fresh foods, but with conventional equipment, in such cases, the operator can either address this by keying in the amount of the discount, or know exactly when to discount. In such a case, the selling price stored in the product file is changed to the discount amount by software at that time.

[0004]

However, such a conventional merchandise sales data processing apparatus has the following problems to be solved.

[0005] First, when the operator inputs the discount amount by key, the operator must perform the processing.
This not only puts an extra burden on the operator because of the time required for processing, but also causes erroneous input.

When the selling price is changed to the discount amount by software at a certain time, no extra burden is given to the operator, but when the product to be discounted is changed, the data must be re-entered each time. However, the processing for this is complicated and troublesome, and the discount amount may be changed for each product even with the same product code, and such a case cannot be dealt with.

[0007]

According to the present invention, there is provided a merchandise sales data processing apparatus comprising: a bar code reader for optically reading bar-coded data; and a bar code data of the bar code read by the bar code reader. Means for discriminating that the barcode data is product data; and when the barcode data of the barcode read by the first means is discriminated to be the product data, a product registration process based on the read product data. , A second unit for determining that the barcode data of the barcode read by the barcode reader is discount or discount data, and a barcode read by the second unit. If it is determined that the barcode data is discount or discount data, the It includes a discount discount processing means for executing the discount process or discount process, against the product data read by the bar code.

[0008]

According to the present invention, when bar code data including discount or discount data is read, bar code product data read immediately before or immediately after the bar code data is subjected to discount processing or discount processing. it can.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 2 is a perspective view showing an ECR according to an embodiment of the present invention. The ECR comprises a main body 1 and a drawer 2 connected to the main body 1 for storing change and the like. The main unit 1 has a numeric keypad, department key, subtotal key,
A keyboard 3 including a deposit / current key and a clear key, a cashier display 4 on the far right side, a printer 5 for issuing a receipt, and a customer display 6 are provided on the left side.

The main body 1 is provided with a touch scanner 7 (bar code reader) electrically connected to the main body 1. The touch scanner 7 optically reads a bar code, and reads the bar code data read each time.
Is stored in an input data storage area described later.

Next, FIG. 1 is a block diagram showing hardware of the ECR according to the present embodiment, and a central processing unit (CPU).
A read-only memory (ROM) 12 storing various operation programs and a random-access read / write memory (RAM) 13 for storing various data are electrically connected to a bus line 14. . Also, CPU
Reference numeral 11 denotes the touch scanner 7 via an I / O port 15, and the drawer 2 via the I / O port 16.
Further, a printer drive circuit 17 for driving the printer 5 for issuing a receipt is connected. Furthermore, CPU
The cashier display 4 and the customer display 6 are connected to the display 11 via a display controller 18, and the keyboard 3 is connected via a keyboard controller 19.

In the RAM 13, an input data storage area 20 (storage means) for storing barcode data sent from the touch scanner 7, and a normal registration flag area 2 for storing a value as a normal registration flag described later.
1, a discount registration flag area 22 for storing a value as a discount registration flag for a discount or discount (hereinafter, representatively referred to as a discount) registration process, and setting as a time flag value whether a timer has passed a predetermined time or not. And a discount barcode data storage area 24 for storing discount barcode data (discount data) read from an input data storage area 20 to be described later.

Next, the program control of the normal operation in the registration mode of this embodiment will be described with reference to the flowchart of FIG.

First, in step (hereinafter abbreviated as SP) 1, it is checked whether data exists in the input data storage area 20 or not. This data is bar code data from the touch scanner 7 or data manually input from the keyboard 3 in accordance with a product registration operation. Then, if data exists in the input data storage area 20, the registration processing shown in FIG. 4 is performed, and then it is determined in SP2 whether a closing operation such as pressing a subtotal key has been performed. When the next product data is present in the input data storage area 20, the registration process of the next product is performed. When the closing operation is performed, the total amount and the like are displayed on the display units 4 and 6 and the printer 5 is used. The receipt is issued and the registration process for one customer is completed.

Next, a registration process in the case where data exists in the input data storage area 20 in this embodiment will be described with reference to FIG.

First, looking at the upper two digits of the data stored in SP11 and SP12, the input data storage area 20
It is determined whether the data stored in is the normal product data or the bar code data for discount (determination means). S
If the upper two digits are “21” in P11, it is normal product data, so the sales quantity of the product file specified by the product code included in this product data in the RAM 13,
A normal registration process for updating the sales amount and the like is performed.

Next, in SP13, it is determined whether the discount registration flag in the discount registration flag area 22 is "1". When the discount registration flag is "1", it indicates that the bar code data for discount has been input immediately before, and when the discount registration flag is "0", the bar code data for discount is still input. Is not shown.

If the discount registration flag is "0" at SP13, since the bar code data for discount has not been input, the normal registration flag in the normal registration flag area 21 is set to "1", and then the timer is started. Then, the one-item registration process ends.

If the upper two digits are not "21" in SP11, it is determined in SP12 whether the upper two digits are "28" or "29". If the upper two digits are "28" or "29", the barcode for discount is used. Since data is stored, SP14
It is determined from the value of the time flag stored in the time flag area 23 whether the timer has passed the predetermined time. Specifically, if the value of the time flag is “1”, it is determined that the predetermined time has elapsed. If the value of the time flag is “0” in SP14, that is, if the predetermined time has not elapsed, then the SP
At 15, it is determined whether the normal registration flag in the normal registration flag area 21 is "1". When the normal registration flag is “0”, since the normal product data is not stored in the input data storage area 20 immediately before, the discount barcode data is stored in the discount barcode data storage area 24 and the next barcode data is stored. Then, the discount registration flag is set to "1", the timer is stopped, and the processing ends.

At SP15, the normal registration flag is "1" (immediately before the normal product data is stored in the input data storage area 20).
If the discount registration flag is "1" in SP13 (the barcode data for discount was stored in the input data storage area 20 immediately before) in SP13, the next SP
At 16, it is determined whether the upper two digits are "28" or "29". If the upper two digits are "28", discount processing is performed from the sales amount updated in the above-described normal registration processing at the discount rate stored in the discount barcode data storage area 24, and if "29", the discount rate is used. With the discount amount stored in the cited barcode data storage area 24, a discount process is performed from the sales amount updated in the above-described normal registration process. Then, the values of the normal registration flag, the discount registration flag, and the time flag are set to “0”, the contents stored in the discount barcode data storage area 24 are cleared, the timer is stopped, and the process ends.

If the value of the time flag is "1" at SP14, that is, if the predetermined time has elapsed, even if normal product data is stored in the input data storage area 20 immediately before, it is the product data of the previous product. It is determined that there is
In step 5, the same processing as when the normal registration flag is "0" is performed.

If the upper two digits are neither "28" nor "29" in SP12, other data processing is performed.

In the ECR having such a configuration, when selling goods at a normal price without discount processing or discount processing, a normal bar code is read by the touch scanner 7. Since the upper two digits of the read product data are “21”, normal registration processing is performed. In this state, the discount registration flag is "0", so that the normal registration flag is set to "1", the timer is started, and the process ends. Therefore, the normal registration process for each product is performed by reading a normal barcode for each product.

Next, when performing the discount processing or the discount processing, the touch scanner 7 causes the normal bar code and the bar code quote bar code to be read successively. At this time, either barcode may be read first.

First, a description will be given of a case where a normal bar code is read first, and then a discount bar code is read within a predetermined time. When a normal barcode is read, the same registration processing as in the case of selling the commodity at the normal price is performed. Then, when the bar code for discount is read within a predetermined time, the upper two digits of the bar code data for discount read are "28" or "29" and the normal registration flag is "1". , The upper two digits are “28” or “2
9 or “9”.

Next, let the user read the bargain quote barcode first,
Next, a case where a normal barcode is read will be described. First, when the bar code for discount is read, the bar code data for discount is “28” or “29” and the normal registration flag is “0”. It is stored in the barcode data storage area 24. Then, the discount registration flag is set to “1”, and the process ends. Subsequently, when the normal bar code is read, the upper two digits of the read product data are "21", so that the normal registration process is performed. Then, since the discount registration flag is “1”, a discount process or a discount process is performed depending on whether the upper two digits are “28” or “29”.

Therefore, for example, a label with a normal bar code is attached to the product in advance, and the bar code is read by the touch scanner 7, so that the registration process of the product at the normal price can be performed. Alternatively, for a product to be discounted, a bar code for discount including data of a discount rate or a discount amount is attached near a normal bar code, so that two bar codes can be read in succession easily and reliably. Discount processing or discount processing can be performed without erroneous operation. Further, even if the product to be discounted or discounted changes, it is only necessary to attach a label to the product. Furthermore, even if the discount rate and the discount amount change from day to day, it can be easily dealt with only by attaching the label.

In this case, if the discount rate or the discount amount included in the discount barcode is provided differently for each label,
It is also possible to change the discount rate or discount amount for each product.

In this embodiment, the discount rate or the discount amount is included in a part of the bar code data to be read. However, the present invention is not limited to this. Each time the discount or discount data ("28" or "29") is input, the discount rate or discount stored for the sales amount of the product code is stored in the product file in advance. Alternatively, discount processing or discount processing may be performed.

In this embodiment, the bar code for discount is attached to a product to be discounted or discounted.
For example, a bar code with a discount bar code is prepared near the ECR, and when registering a product to be discounted or discounted, the bar code for the bar code is attached to the bar code attached to the product. You may make it read.

[0032]

As described above, according to the present invention,
Discount processing and discount processing can be performed easily and reliably without erroneous operation.Even if the discount rate or discount amount is changed, the barcode of the changed discount data or discount data is attached to the product, and the product data Simply by reading just before or immediately after reading the barcode, discount processing and discount processing can be easily performed, and discount processing and discount processing can be performed for both source marking barcodes and in-store marking barcodes. .
