Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an electronic cash register incorporated in a PoS system, and in particular to a transaction data file that stores transaction data for each product sold to one customer. The present invention relates to an electronic cash register provided with an electronic cash register.

[Prior Art] Some POS systems adopted for sales registration operations in department stores, supermarkets, etc. send transaction data generated at each electronic cash register to a file control unit via a transmission path, and the file control unit Record each transaction data received from the electronic cash register in a recording device such as a -H floppy disk recording device in the order of input,
Later, if necessary, for example, you can aggregate by department code,
In the case of sales by credit card, etc., there is a system in which totals are calculated by card type. [Problems to be solved by the invention] However, in the electronic cash register incorporated in the POS system configured as described above, the following There was a problem like this. That is, in an electronic cash register, when transaction data such as the department code, number of items sold, and sales amount of a sales item is entered from the keyboard, it is immediately sent to the file control section via the transmission path. In a system in which transaction data for one product is sent to the file control unit each time the data for one sales product is input, for example, one customer purchases multiple products and makes payment using an electronic cash register. If the cashier wants to cancel the purchase of all products during the process, the cashier needs to cancel and register each registered product one by one by key operation.

Therefore, the cancellation operation becomes complicated.

In addition, with the spread of credit cards, electronic cash registers have been developed that can carry out product sales registration operations even with credit cards.

In such an electronic cash register, all transaction data for products sold by credit card must be sent to the file control unit because the payment will be billed to the card issuing company later. However, in the case of selling for a premium, only the transaction data required for data processing by the file control unit need be transmitted. For example, there is no need to send transaction data of products that have not been statisticized or aggregated by the file control unit.

However, since it is conceivable that a customer may submit a credit card just before the cashier presses the closing key, it is necessary to send all transaction data to the file control section, regardless of whether it is used by the file control section or not. Therefore, each electronic cash register and file control unit performs a very wasteful task of transmitting and receiving unused transaction data.

The present invention has been made based on the above circumstances, and its purpose is to provide a transaction data file that stores transaction data for each product sold to one customer, and to synchronize it with input of closing commands. By sending the stored contents of this transaction data file to the file control section,
Only the necessary data can be sent to the file control unit, and P
An object of the present invention is to provide an electronic cash register that can improve the processing efficiency of the entire OS system.

Another object of the invention is to provide an electronic cash register in which, in addition to the above-mentioned object, it is possible to easily cancel all orders before inputting a closing command.

[Means for Solving the Problems] The electronic cash register of the present invention has a transaction data file that stores each transaction data for each product sold to one customer, and each transaction data stored in this transaction data file. and a status memory for storing information on whether or not to send the information to the file control unit, and in response to input of a closing command indicating the end of sales registration work for one customer, the information in each status memory indicates transmission. In addition to selecting transaction data and sending it to the file control unit, it also processes all transaction data at once in response to a closing command input when card information indicating credit sales is input during sales registration for one customer. The data is then sent to the file control section.

In addition to the above-mentioned invention, another invention is such that when a batch cancellation command is input during sales registration work for one customer, the stored contents of the transaction data file are canceled all at once.

[Operation] With the electronic cash register configured in this manner, input transaction data is temporarily stored in the transaction data file during sales registration work for a product sold to one customer. Then, when a closing command is input, only transaction data whose information in the status memory in the transaction data file indicates transmission is selected and sent to the file control section. Further, when card information is input during sales registration work, all transaction data in the transaction data file is sent to the file control section in synchronization with the input of the closing command.

In addition to the above-mentioned effects, another feature of the present invention is that when a batch cancellation command is input during sales registration work for one customer, the stored contents of the transaction data memory are canceled all at once.

[Example] An embodiment of the present invention will be described below with reference to the drawings.

floppy disk control section 43. It also controls the DMA control section 44 and the like for directly transmitting data between the transmission control circuit 41 and the floppy disk control section 43.

In each of the electronic cash registers 3, when a key signal is input from the keyboard 5 as an input device, the CPU 19 is configured to execute a sales registration process according to the flowchart shown in FIG. That is, when a key signal is input to the keyboard input circuit 23, after confirming that the control key 14 is set to the [registration] business mode, the type of the input key signal is checked. And P
If the key signal input at l is that of numeric key 10, the numeric data entered with this numeric key 10 is stored in the RAM.
22 in number buffer R2.

If the key signal input at P2 is from the department key 11, the input department code is stored in the department buffer R3. If the key signal input at P3 is that of the amount key 15, it is determined that transaction data consisting of the department code and sales amount for one sales item has been input, and each value is input to the number buffer R2 and department buffer R3. After confirming that the data is stored, the department code in the department buffer R3 and the numerical data in the number buffer R2 are read out as sales amounts and cumulatively registered for each department code in the sales registration file R1 in the RAM 22. Also, this sales amount is added to the total amount on the totalizer R5. At the same time, the printer 25 prints out the department code and sales amount on the receipt. Furthermore, it is stored in the department area R9 and amount area R11 of the transaction data file R4.

Incidentally, if there is no manual key operation of the X key in advance, the number of sales points is determined to be 1, and 1 is stored in the point area R10. Furthermore, the status memory R8 stores information as to whether or not the transaction data of this sales product is data that should be sent to the file control unit 1.
Set to area [1] of Information on whether to send or not is determined in advance for each department code. When the storage of one transaction data is completed, the number buffer R2 and department buffer R3 are cleared.

If the key signal input at P4 is from the discount key 18, it is determined that the numerical data stored in the numeric buffer R2 is the discount amount, and the discount amount is calculated from the total amount of the totalizer R5. At the same time, the sales amount of the department code registered earlier in the sales registration file R1 is reduced.

At the same time, the discount amount is printed out on the receipt along with the discount message. Further, a bit of 1 is stored in the area [3] indicating a discount in the status memory R8 of the transaction data file R4, and the discount amount is stored as one piece of transaction data in the amount area R11.

If the key signal input at P5 indicates the cancel key 17, it is determined that the transaction data consisting of the sales amount and department code stored in the number buffer R2 and department buffer R3 has been canceled, and the sale is canceled. After the registration file R1 and totalizer R5 are reduced, the department code and sales amount to be canceled are printed out on the receipt, and a broken line indicating the cancellation is superimposed on these characters. Next, the cancellation of status memory R8 of transaction data file R4 is shown [
A bit of 1 is stored in the area of 4]. Then, the department code and sales amount to be canceled are stored as one transaction data in the department area R10° and the amount area R11, respectively.

If the key signal input at P6 is the batch cancellation key 16, all the registrations of the products sold to this customer up to now will be canceled, so sales will be made according to each transaction data stored in the transaction data file R4. In addition to reducing the sales points and sales amount for each department in registered file R1, totalizer R
5 and all stored contents of transaction data file R4 are cleared.

The flag area R6 and card information area R7 are also cleared.

If the key signal input at P7 is from the total key 13, the total amount of the totalizer R5 is printed out on a receipt by the printer 25, and the receipt is cut and ejected from the receipt issuing port 8. Next, if the card input flag in the flag area R6 of the RAM 22 is set to 1, it is determined that the card information has been input by the card reader 9 during sales registration for - customers, and the card information is Area R7 (
7) Read card information including company code, membership number, etc. It also reads out all transaction data stored in transaction data file R4. Then, all the read transaction data is sent together with the card information to the file control section 1 via the transmission path 2. Thereafter, the card input flag in the flag area R6 is reset to 0, and the transaction data file R4, totalizer R5, and card information area R7 are cleared.

If the card entry flag in the flag area R6 is cleared to 0, it is determined that this is a cash sale for this customer, and a 1 is written in the [1] area of the status memory R8 in the transaction data file R4. Only the transaction data in which pits are set are selected and sent one after another to the file control unit 1 via the transmission line 2. After that, transaction data file R4 and totalizer R5 are cleared.

When a credit card is inserted into the card reader 9, the card input flag in the flag area R6 of the RAM 22 is set to 1 as shown in FIG. Information area R
Store in 7.

The file control unit 1 that has received the transaction data from each electronic cash register 3 temporarily stores the received transaction data in the RAM.
After storing the transaction data in the RAM 34, when the storage capacity of the RAM 34 reaches its limit, the transaction data is moved to an external floppy disk recording device 42.

Then, transaction data is read out from this floppy disk recording device 42 and various data processing is performed as necessary.

In the electronic cash register 3 configured in this way, for example, the department code 11. Suppose that two products are sold for a unit price of 1,200 yen and the transaction data needs to be sent to the file control unit 1, and the cashier presses the numeric key 10 of [2] as shown in FIG. 8(a). x key, [1] department key 11.1200 numeric key 10. When the amount keys 15 are manually operated in sequence, as shown in FIG.
Each of the above data is stored as transaction data.

At the same time, as shown in FIG. 8(b), the department code, number of items sold, unit price, and total amount of two items (2400) are printed out on the receipt 45.

Furthermore, if you want to discount 200 yen, 200 numeric key 1
0. When the discount key 18 is manually operated, Fig. 1(b)
As shown in the figure, 1 is set in the [3] and [1] areas of the status memory R8 of the transaction data file R4, and 200 is stored in the amount area R11. At the same time, as shown in FIG. 8(b), a discount message and a discount amount [2001] are printed together with a (-) sign on the receipt 45.

Further, in order to cancel the 1200 yen product with department code 2 immediately after it has been registered, the cancellation key 17 is operated manually. Then, as shown in FIG. 1(b), transaction data with the same transaction data registered earlier but with area [4] of the status memory R8 set to 1 is stored in the transaction data file R4.

At the same time, a broken line indicating cancellation is printed over the already printed department code and amount on the receipt 45.

Although not shown, a total key 13 indicates the completion of the sales registration process for a product sold to one customer.
When the key is manually operated, only the transaction data whose transmission information to the file control section 1 is set to 1 in the transaction data file R4 are sent to the file control section 1 at once. For example, the transaction data (department code 5, sales amount 300 yen) with bit 0 in the [1] area of status memory R8 stored in the fifth position of the transaction data file in FIG. 1(b) is sent to file control 1. Not done. Also, total key 1
When the card information is read by the card reader 9 during the sales registration operation before the key operation in step 3, all transaction data in the transaction data file R4 is sent to the file control section 1 in synchronization with the key operation of the total key 13. Ru.

Furthermore, if the batch cancellation key 16 is manually operated during sales registration work before the total key 13 is operated, all transaction data stored in the transaction data file R4 is erased at once. Therefore, transaction data that has been canceled all at once is not sent to the file control unit 1.

In this way, when the sales registration work for one customer is completed, the transaction data for each sales product is sent to the file control section 1 all at once. Therefore, when selling credit cards, all transaction data is sent,
When making a cash sale, it is possible to select and send only the necessary transaction data. Since there is no need to send out unnecessary transaction data when selling the real money, it is possible to improve the efficiency of data transmission operations in the electronic cash register 3 and the file control section 1 using the transmission line 2. Therefore, the processing efficiency of the entire POS system can be improved.

In addition, in the electronic cash register 3, the total key 13
Since it is possible to cancel all transaction data in the transaction data file R4 at once using the batch cancellation key 16 before operating the keys, the cancellation operation is simplified compared to conventional electronic cash registers, and the burden on the cashier is reduced. It is possible to reduce the amount of stress and improve the efficiency of the entire sales operation using electronic cash registers.

[Effects of the Invention] As explained above, according to the present invention, a transaction data file is provided that stores transaction data for each product sold to one customer, and this transaction data file is updated in synchronization with input of a closing command. The stored contents are sent to the file control section. Therefore, only necessary data can be sent to the file control section, and the processing efficiency of the entire POS system can be improved.

In addition, you can easily cancel the tightening commands all at once before inputting them.
It is possible to significantly improve the efficiency of sales registration work.
