Abstract

PURPOSE:To reduce working load of an operator in dealing with plural number of the same commodity, by setting total number of commodities by an input key, operating a multiplication key and performing scanner operation once. CONSTITUTION:Registered data are stored by an input key 11 in the registered area of a memory 13. A registered multiplication flag by the input key 11 before inputting of a scanner 12 is provided in the memory 13. When inputting to the scanner, if the state of the flag is off, ordinary processing is performed. That is, scanner inputted commodity is dealt with as it is. If the flag is on, the product of scanner inputted unit price of the commodity and the contents of storage of the registered area are dealt with as sales data.

Description

DETAILED DESCRIPTION OF THE INVENTION (a1) Related Field of the Invention The present invention relates to an electronic cash register with a scanner, in which a product code can be entered using a scanner.

fbl Disadvantages of the conventional technology In the conventional electronic cash register with a scanner,
It is necessary to use a scanner to trace the barcode printed on the tag of each product.

However, if multiple items of the same item are brought in in one transaction,
This reduces efficiency as the same barcode is scanned multiple times. Particularly when processing many identical products at once, the scanner operation takes a long time, and the receipt becomes unnecessarily long.

(C1 Purpose of the Invention The purpose of the present invention is to provide an electronic cash register with a scanner that allows easy operation and quick transaction processing when multiple items of the same type are brought in at once.

(Configuration and effects of d1 invention This invention can be summarized as follows.

A numeral area is allocated to the memory work area in the same way as conventional registers. This number area stores the number data set with the input keys. Further, a number setting/multiplication flag is provided in the memory to store the number set by the input key before manual input of the scanner and whether or not the fJl arithmetic key is operated. When using the scanner manually, check the status of this flag, and if it is off, the transaction will be processed as normal, that is, the product manually processed by the scanner will be processed as is. If the flag is on, the transaction is processed using the multiplication value of the unit price of the product entered manually by the scanner and the content stored in the number area as sales data. Therefore, if you enter the number of identical products you wish to trade at once in the number area, the transaction process will be completed by operating the number and multiplication keys once and operating the scanner once. .

In this way, when processing multiple transactions for the same product at one time, the present invention allows the operator to set the total number of products using the input key, operate the fJl calculation key, and then operate the scanner once. Work load is reduced and transaction processing is completed in a short time. Furthermore, since there is no need to output a receipt for each product, there is an advantage that the receipt becomes shorter and transaction details are easier to see.

Description of tel Embodiment FIG. 1 is a key arrangement diagram of an electronic cash register with a scanner according to an embodiment of the present invention, and FIG. 2 is an overall block diagram of the same register.

In FIG. 1, 1 is a numeric key, 2 is a department key, and 3 is an operation mode switching lock. Number key 1 is clear key 1
It includes the function keys a, JJ+arithmetic key 1b. The mode switching lock 3 is for file change mode FP, registration mode REG, inspection mode X, settlement mode Z and power OFF.
Switch F.

As shown in FIG. 2, this register includes the CPU 10, the keyboard 11. Scanner 12. It is composed of a memory 13, a printer 141, and a display section 15. The memory 13 is RO
The RAM includes a data file consisting of a PLU (Price Lookup) file and a departmental file, and a work area. Note that the operation mode switching lock 3 during normal transactions is set to the registration mode REG.

Figure 3 shows the structure of the data file. The figure Ta) is P
The structure of the LU file in the same figure (bl indicates the structure of the departmental file.

The PLU file consists of N blocks of transaction data with product numbers 1 to N. Each block consists of five items of data: product code, product name, unit price, number counter representing the number of units sold for that product, and department to which it belongs. configured. Departmental files as well.
It consists of N blocks of transaction data with department numbers 1 to N, and each block consists of a department name, unit price, a counter that represents the number of units sold in that department, and a totalizer that represents the sales amount in that department. .

FIG. 4 is a configuration diagram of a work area allocated to the RAM.

The work areas include a number area WORKI that stores the number data entered using the number key 1, a multiplication value area WORK2 that stores the multiplication value of the number data entered by the scanner and the unit price of the product manually entered by the scanner, and a number area WORK2 that stores the product unit price manually entered by the scanner. It has a number setting flag FKN that turns on when the scanner is operated, and a number setting/multiplication flag FCMLT that turns on when the number setting and multiplication keys are operated before the scanner is manually operated.

Next, the transaction processing procedure when the scanner is operated manually will be explained with reference to the flowchart shown in FIG.

When the power is turned on, the process proceeds to step nl (hereinafter step ni will simply be referred to as ni), and the registration mode is checked. After confirming that it is the registration mode, proceed to n2-n3 to clear the work area and initialize. Next, at n4 and n5, wait for scanner power or key power. If there is input from the scanner 12, proceed from n4 to 06; if there is input from the keyboard 11, proceed to n5
Proceed to n13.

In the case of a normal manual scanner, proceed to n4-”n6,
First, check the cent status of flag FKH. As will be described later, if the number is set before the scanner, the flag FKN is 1 at this stage, and the result is n.
4-" Proceeds to n25 and error processing is executed. If the number and multiplication keys have been operated before the scanner manual operation, and if the scanner manual operation is the first operation, proceed to n4.
-+ Proceed to n6-n7. At n7, the transaction data of the manually entered product code is read out from the PLU file. Then print the product name on the receipt (n8)
.

Next, the set state of the flag FCMLT is checked at n9. As described later, if the number and multiplication keys are operated before the scanner is manually operated, this flag FCMLT will be set to 1.
Since it is set to , the process proceeds from n9 to n20. Therefore, in the case of a normal manual scanner, from n9 to nlO
Proceed to.

nlO and nll are normal transaction processing procedures in the case of manual scanner operation. First, in nlO, the counter in the transaction data read out in n7 is incremented by l. then nil
Then, add 1 to the counter (department file) of the department to which the product code belongs, and then add the unit price of the product to the totalizer.

Then, at n12, the unit price is printed and the transaction process is completed.

On the other hand, when the number is placed in front of the scanner, steps n13 and below are executed before proceeding from n4 to n6. In n13,
It is determined whether or not the multiplication key 1b is operated. If the input key is a multiplication key, the process proceeds to n17; otherwise, the process proceeds to n14. Further, at n14, it is determined whether the input key is a numeric key, and if it is a numeric key, the process advances to n14=n15. Therefore, if a numeric key is entered first, n5-
Proceed to n13→n14-n15. At n15, the numeric data is stored in the numeric area WORKI.

Next, flag FKN is set to 1 (n16). After the set number data is stored as described above, operating the multiplication key 1b will result in 1. Proceed to n5-'n13-'n17. At n17, the state of the flag FKN is determined. If the flag is FKN-0 here, it means that the multiplication key was operated before entering the number, so another process is performed. Therefore, after setting the number, if the multiplication key 1b is operated, the process advances to n17-n18, and then the flag FcM
Determine the set state of LT. When this step is executed for the first time, the flag F CM L T = 0, so the process goes from n18 to n19 and the flag FCML
Cent at T=1. That is, this flag FCM
By setting LT to 1, the operation of the numeric and multiplication keys is memorized.

After completing the above steps, go back to n3, clear the number area and flag FKN, and wait for scanner manpower.

When there is a man in love with the flag FKN=O and flag FCMLT=1, n4--n8 is executed and the name of the input product is printed on the receipt.

Then, at n9, the flag is determined to be F'CM L T -1, and the process proceeds to n20. In n20, the unit price of the input product (PL
The storage contents of the number of devices area WORKI consisting of the U file are multiplied, and the result is stored in the multiplication area WORK2.
Stored in At this stage, the number area WORK
Since the input value entered before the scanner was manually stored is stored in I, the multiplication value of the input value before the scanner's manual effort and the product unit price is stored in the multiplication area WORK2. Therefore, if the number data is set as the total withdrawal of the same product, the 'sales data of the same product will be set in the multiplication area WORK2 at the stage n20.

Then, add the number of products in the number area WORKI to the number counter in the PL and U files (n21), and the number counter in the departmental file (n22), and add the sales data in the multiplication area WORK2 to the departmental file. Quantity, unit price (n23) and multiplication result (n2
4) is printed to complete the transaction process.

As described above, at the beginning of a transaction, if you first enter the total number of identical products, then operate the multiplication key and then use the scanner manually, you can directly calculate the product unit price read from the PLU file.
Sales data is calculated by multiplying the total number of products entered, so
Transactions can be made quickly and operations are very simple.
