As shown in FIG. 16, this electronic cash register consists of an apparatus main body 1 and a card issuing machine 2 provided adjacent to the main body 1.

On the top surface of the device main body l, a keyboard 3 consisting of a numeric keypad 3a and a mode key 3b, a receipt issuing port 4,
A display 5 is provided.

However, the mode key 3b is made up of a plurality of keys such as an amount key and a department key. Further, the card issuing machine 2 has a card issuing opening 2a formed on its front face, and a large number of cards 6 having magnetic stripes 6a are stored in advance.

Further, this electronic cash register has a hardware configuration as shown in FIG. are connected.

However, the memory 8 includes a ROM that stores a program for performing registration processing, a program for performing card issuing processing, etc., a card department sales amount save area,
RA with sales data area, aggregate data area, etc.
It is formed by M. Further, the printer 9 issues a printed receipt from the receipt issuing port 4.

When registering a product in such an electronic cash register, if a key is pressed on the keyboard 3, the total sales amount of the card department stored in the total data area of the RAM is stored in the card department sales amount save area. let

Then, after the department code of the product is input using the numeric keypad 3a of the keyboard 3, the department key of the mode key 3b is pressed, and furthermore, after the amount of the product is input using the numeric keypad 3a, the amount key of the mode key 3b is pressed. At this time, the above-mentioned department code and amount are sequentially stored in the sales data area of the RAM. However, the department code is preset for the product, such as rlj for the card department and 2j for the vegetable department.

This operation is performed on all registered products, and when the operation is completed, the payment key of the mode key 3b is pressed. At this time, based on the storage contents of the sales data area of the RAM, the amounts of the input products are stored cumulatively in the total area of the RAM for each department, and then the total amount of the input products is calculated. The total amount of the card department stored in the card department sales amount save area (the amount before registration processing) is subtracted from the total amount of the card department stored in the total area of The issuer 2 writes the subtraction result on the magnetic stripe 6a of the card 6 and issues it.

Problems to be Solved by the Invention Generally, in such an electronic cash register, when a card 6 is issued due to a mistake by the cashier, or when a previously issued card is refunded at the request of a customer. , the cashier discards that card 6.

On the other hand, such an electronic cash register stores the total sales amount of the card 6 in the totaling area of the RAM, but does not manage any data regarding the discarded bills.

For this reason, crimes such as fraudulent refunds based on discarding counterfeit cards cannot be prevented.

Means for Solving the Problems In an electronic cash register that performs data processing such as issuance of prepaid cards based on input data from an input means, an issuance number storage means for storing the number of issued prepaid cards and a means for discarding prepaid cards are provided. a discarded bid number storage means for storing the number of bills; and a discarded bid determination means for determining whether or not a prepaid card can be discarded based on the stored contents of the discarded bid number storage means and the stored contents of the issued number storage means. , and a bid discarding means for discarding prepaid cards based on the determination result by the discarding possibility determining means.

The number of issued prepaid cards is stored by the issued number storage means, the number of discarded prepaid cards is stored by the discarded bid number storage means, and the number of discarded bids stored is based on the memory content of the number of discarded bills storage means and the number of issued cards is stored by the number of issued number storage means. The scrapping determination means determines whether or not the prepaid cards can be scrapped, and the scrapping means scrapes the prepaid cards based on the determination result. It can be eliminated.

Embodiment An embodiment of the present invention will be explained based on FIGS. 1 to 15. As shown in FIG. 1, this electronic cash register is provided with a keyboard 12 as an input means, a printer 13, and a display 14 on the upper part of a drawer 11, and a device main body 15 is provided adjacent to the side thereof. It is something that is made possible.

On the other hand, this electronic cash register has a hardware configuration as shown in FIG.
16, a clock circuit 19, a buzzer 20, and a printer interface 13a connected to the printer 13;
A prepaid interface 21a connected to the prepaid card reader/writer 21, a display controller 14a connected to the display 14, and the keyboard 1.
The keyboard controller 12a connected to the keyboard controller 2 is connected to the drawer 11.

However, the ROM 2 stores fixed data such as programs that control the CPU 16 to perform various tasks such as registration, inspection, and payment.

The RAM 18 also stores a product data table (not shown) that stores product data including product department codes, unit prices, etc., as well as a product data table (not shown) that stores product data including product department codes, unit prices, etc. As shown in FIG. 000 yen ticket, 3,000 yen ticket, etc.)
Storage units include an issued number table 18a as an issued number storage means stored in the storage unit, and a discarded bill number table 18b as a discarded bill number storage means for storing the number of discarded prepaid cards by type as shown in FIG. was formed.

In such a configuration, input data from the keyboard 12 is sent to the CPU 1 via the keyboard controller 12a.
6. At this time, the CPU t6 has R
Based on the program stored in OM17, RAM
In addition to performing memory processing on the prepaid card reader/writer 18, the prepaid card reader/writer 21 transmits and receives data to and from the prepaid card reader/writer 21 via the prepaid interface 21a, and transmits display contents to the display controller 14a to display them on the display 14.

That is, when issuing a prepaid card and discarding it, the keyboard 12 is used as shown in FIG.
When the prepaid card issuance/disposal task is selected, the display 14 displays the task selection screen (see Figure 7), and then enters the key manual standby state. When the selection is made, it is determined whether the input data from the numeric keypad is 1 or not.

Input data is 1 (card issuing business was selected)
If it is determined that
,000 yen, 3,000 yen, 5,000 yen, 10.00
After displaying the card type (0 yen), the system enters the key manual standby state, and when the selection is made using the numeric keypad and the registration/repeat key on the keyboard 12, a closing registration waiting display is performed (Figure 9 shows the number = 1).

After receiving the payment from the customer, the cashier enters the amount using the ten keys on the keyboard 12, and then performs a closing operation by pressing the customer level key. When this customer key is pressed, card processing is displayed (see Figure 10)
After that, card issuance processing is performed. When this card issuance process is completed, the card issuance completion display (see Fig. 11) is performed, and then the number of issued cards is determined by the corresponding card type (cartridge number, etc.) in the number of issued cards table 18a.
The cumulative total is stored in the number area corresponding to , and the card issuing process is ended.

On the other hand, when the selection is made using the numeric keys and the registration/repeat key of the keyboard 12 after the above-mentioned task selection screen (see FIG. 7) is displayed, it is determined whether the input data using the numeric keys is 1 or not. In the process, if it is determined that the input data is not 1 (card scrapping service has been selected), the display 14 displays the card insertion guidance screen (first
(See Figure 2) is displayed, and then the card enters the standby state.
When a prepaid card is inserted, a waiting display for pressing the customer level key is displayed (see Figure 13), and when the customer level key is pressed, a card processing display is displayed (see Figure 14), and then card disposal processing is performed. . When this card scrapping process is completed, a card scrapping completion display is displayed (see Figure 15).
After performing this, the number of discarded prepaid cards is accumulated and stored in the number area corresponding to the corresponding card type (cartridge N0,) in the number of discarded cards table 18b, and the card discarded bid process is completed.

Here, in the above-mentioned card scrapping process, as shown in FIG. 6, when the customer key is pressed after a prepaid card is inserted, the data of the prepaid card is read by the prepaid card reader/writer 21. is stored in the RAM 18 via the CPU 16 from the prepaid interface 21a. The issued number data corresponding to the card type (cartridge No.) obtained from this memory content is read from the issued number table 18a, and the discarded bill number data corresponding to the same card type is read out from the discarded bill number table 18b.
Read from.

Furthermore, based on these reading results, the discarding possibility determining means determines whether or not the discarding process can be performed.

If it is determined that it is possible to discard bids (the number of issued bids is greater than the number of discarded bids), after performing the discard process using the discarding means, the number of discarded bids is stored as the corresponding number in the number of discarded bids table 18b. The cumulative number of cards is stored in the number area corresponding to the card type (cartridge N00) and the discarding process is completed, and
If it is determined that discarding bids is not possible (the number of issued bills is not greater than the number of discarded bills), error processing is performed.

In this way, prepaid cards are discarded based on the management of the number of cards issued and the number of discarded cards, so there is no need to discard more than the number of issued cards, and this prevents counterfeit cards from being discarded. This makes it possible to prevent crimes such as fraudulent refunds.

Effects of the Invention As described above, the present invention stores the number of prepaid cards issued by the issued number storage means, stores the number of discarded prepaid cards by the discarded number storage means, and stores the stored contents of the discarded number storage means. The scrapping determination means determines whether or not the prepaid card can be scrapped based on the contents stored in the issued number storage means, and based on the determination result, the scrapping means scrapes the reprepaid card. It is possible to eliminate the need to discard more than the number of bids. Therefore, crimes such as fraudulent refunds based on discarding counterfeit cards can be prevented.
