Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic cash register (hereinafter referred to as an ECR), and more particularly to an ECR in which a plurality of operators can alternately register single-price information of a product purchased by a customer.

2. Description of the Prior Art A conventional ECR is provided with a memory for storing the total amount of individual items of products registered by an operator for each operator. The sales information for each operator stored in this memory is read and managed at regular intervals. On the other hand, when a customer offers to return the purchased product, a correction operation can be performed so that the single item price information of the product can be subtracted from the accumulated amount in the memory. Therefore, in the conventional ECR, when transacting with a customer, all the single item price information of the products purchased by that customer is registered, the total amount is displayed, and after receiving money from that customer, all transactions with that customer There is a drawback that a fraudulent operation can be easily performed by performing a correction operation to cancel the transaction, setting the transaction amount to 0, and allowing the operator to accept the amount received from the customer. Such injustice was particularly prominent overseas.

OBJECT OF THE INVENTION Therefore, a main object of the present invention is to provide an ECR capable of realizing fraud prevention of an operator.

Structure and Effect of the Invention To summarize the present invention, each time information relating to a product is input from the input means, single-item price information relating to the product is cumulatively stored, and when a correction command is issued, the corresponding product The unit price information is subtracted from the cumulative amount, the number of times the content of the storage means becomes 0 is counted every time there is a total calculation command, and the count value is output. Therefore, when a fraudulent act is carried out and the amount of money received from the customer is taken into account, the number of times that the content of the storage means becomes 0 increases, so that the fraudulent transaction can be easily found.

Hereinafter, the present invention will be described more specifically with reference to the embodiments shown in the drawings.

Description of Embodiments FIG. 1 is a schematic block diagram of an embodiment of the present invention.

Reference numeral 251 is a key that is operated to instruct total calculation and perform cash transactions.

3 and 4 are views for explaining each storage area of the storage means 4 shown in FIG. In FIGS. 3 and 4, the storage means 4 mainly includes an area 41 for storing variable data and an area 42 for storing preset data.
Including and Area 41 is further provided with areas 411 to 415. Area 411 stores data such as standard aggregator and function aggregator. Area 412 cumulatively stores the number of transactions and the total amount for all customers. Area 412 stores the number of transactions (hereinafter referred to as ZBAL sales) in which the transaction amount for one customer is 0. Area 413 stores the number of transactions and the total amount for each operator. area
414 cumulatively stores the total amount and the number of transactions for each department. Area 415 stores a flag (FEC) indicating that correction key 253 has been operated.

Area 42 includes areas 421 to 42n for storing the number of transactions, total transaction and number of ZBAL sales for each operator as shown in FIG.

5 to 9 are diagrams showing a key operation procedure, in particular, FIG. 5 shows an operation example when presetting an operator code, and FIG. 6 shows that the operation of the operator in charge has been completed. 7 is an operation example for setting the normal commodity registration and the transaction total amount to be displayed on the display means, and FIG. 8 is a single item amount information registered by then. Is an operation example for correcting the total transaction amount to 0, and FIG. 9 is an operation example for instructing the creation of a report. FIG. 10 is a diagram showing an example of an operator management report, and FIG. 11 is a flow chart for explaining a concrete operation of an embodiment of the present invention.

Next, a specific operation of the embodiment of the present invention will be described with reference to FIGS. First, the mode selector switch 21 is switched to set the registration mode. And
In accordance with the key operation procedure shown in FIG. 5, enter the operator code 1010 from the numeric keypad 23 and then the operator key 25.
Operate 5. Then, the area 42n of the storage means 4 is specified, and the number of transactions and the total transaction amount after that are specified in this area 42n.
will be stored in n. In addition, when the operator registered by then is replaced, as shown in FIG.
When 255 is operated, the area 42n specified up to that point is released, and the next operator inputs his own operator code, whereby the area of the corresponding storage means is specified.

When a customer purchases a purchased product, one of the department keys 22 corresponding to the purchased product is operated, as shown in FIG. Then, the CPU 1 determines that there is a key input, determines that it is not the correction key, and then determines that the department key has been operated. Thereafter, it is determined whether or not the flag FEC indicating that the correction key has been operated is set, and if not set, from the area 414,
Unit price amount information corresponding to the operated department key is read and accumulated in area 412. Then, the unit price amount information is added to the totalizer of the area corresponding to the department key and the counter is incremented by +1. Further, the unit price amount information of the product is displayed on the display unit 5, and the unit price amount information is also printed on the receipt by the printing unit 6. By repeating this operation, all the information about the products purchased by the customer is registered. After that, when the subtotal key 252 is operated, the total amount of the customer stored in the area 412 is displayed on the display means 5.

Here, it is assumed that the operator performs the key operation shown in FIG. 8 in order to make an illegal act. That is, when the correction key 253 is operated, the CPU 1 determines that the correction key 253 has been operated and sets a flag in the area 415. After that, when any one of the department keys 22 is operated, it is determined that the flag FEC is not 0, the unit price amount information is subtracted from the totalizer of the department, and the content of the corresponding counter is decreased by -1. Then, the unit price amount information is subtracted from the total amount of the area 412, and the fact that the correction is made is displayed on the display means 5, and
The printing means 6 prints the fact that the correction is made. Then, the flag FEC of the area 415 is cleared. Repeat this operation to correct all unit price information of a product purchased by a customer to 0, and then operate the current / total key 251.
1 determines whether or not the frequency counter in the area 412 is 0. Since the operator is performing a correction operation here, 0
It has become. If the counter in area 412 is 0, the ZBAL sales counter in area 412 is incremented by 1, and the ZBAL sales counter in area 42n of the corresponding operator in area 42 is also +.
Do 1 Then, the transaction counter in the area 412 is incremented by 1, and the transaction counter in the area 42n is also incremented by 1. Further, the contents of the totalizer of area 412 are added to the totalizer of area 42n, and the transaction ending process is performed thereafter. Therefore, as shown in FIG. 4, the operator totalizer in the area 42 stores the number of times the operator has made an illegal act.

When the contents shown in FIG. 4 are printed by the printing means 6 to create a report, the mode changeover switch 21 is switched to set the report creation mode, and the report key 254
To operate. Then, as shown in FIG. 10, the entire contents of area 42 are printed. At this time, the CPU 1 calculates the ZBAL occurrence rate based on the number of transactions of each operator and the number of ZBAL sales, and also prints the result on the report. Therefore, as is clear from Fig. 10, the ZBAL occurrence rate of the entire store is about 2.3% of the total number of transactions, while the ZBAL occurrence rate of the operator corresponding to the operator code 1010 is about 1%.
It is extremely high at 5.8%. In this way, it can be determined that there is a high possibility of fraudulent activity when the remarkable occurrence rate is concentrated on a specific operator.
