Abstract

PURPOSE:To protect the hard total against the release of a battery support by storing the transaction data stored to a volatile memory means in parallel to a nonvolatile memory means. CONSTITUTION:The transaction data are totalized every time a register button 6a is pushed for registration of a single product. When a transaction end button 6b is pushed at this time point, the cumulative value of data totalization is printed out to a sheet. Furthermore the cumulative value is added to the cumulative value of hitherto transactions and stored to a C-MOS memory 10. Then all stored data are sent and stored to a bubble memory 17. If a battery support is released and the hard total in the memory 10 disappears, the hard total is read out of the memory 17 with operation of a back-up button 14a after a fault, etc. are recovered. Then this hard total is transferred to the memory 10 and stored to a memory area there.

DETAILED DESCRIPTION OF THE INVENTION (a) Technical Field of the Invention The present invention relates to point of sale management (Point of 5a).
The present invention relates to an electronic register in a system (hereinafter referred to as PO8), and particularly to a transaction data processing device that can protect transaction data stored in a storage unit.

(b) Technical Background Recently, with the spread of computer network systems, POS systems have come to be widely adopted in department stores, supermarkets, and the like. Electronic cash registers are used as terminals in this system.

As shown in FIG. 1, a POS system usually includes a plurality of electronic registers 1a to 1n connected to a control device (hereinafter referred to as T/C) 2.
and is further connected online to the computer center 3 via a line.

The electronic registers 1a to 1n are operated by an operator such as a store clerk, and sequentially display prices of products presented by customers on a display. Finally, the total amount is displayed by pressing a button, and a receipt is issued for each sales transaction by the printer, and a journal is recorded at the same time. This transaction-specific data is stored in the storage sections of the electronic registers la to 1n together with classification data, cumulative data, and the like.

Further, sales information by product is sent one by one to the computer center 3, where comprehensive information management of product management such as sales aggregation, inventory management, and purchase management is performed.

The storage units of the electronic registers 1a to 1n that store transaction data usually use volatile memory, and if the power is turned off due to a failure etc., the stored contents will be lost, so this must be protected. A method is desired.

(C) Prior Art and Problems FIG. 2 is a perspective view illustrating an electronic register to which the present invention is applied, and FIG. 3 is a control block diagram showing the conventional method.

FIG. 2 shows an electronic register 1a as an example of the electronic registers 1a to 1n, including a display 4, a printer section 5.
It is composed of a keyboard 6, a cash drawer 7, and a control section 8. That is, the printer section 5 and the control section 8 are arranged on the left and right sides of the upper surface of the cash drawer 7, the keyboard 4 is arranged in front, and the display 4 is arranged in contact with the back of the keyboard 6.

A receipt issuing port 5a and a slip insertion port 5b are provided at the center of the top surface of the printer section 5.

A slip is inserted into the slip insertion slot 5b when printing and issuing a slip in the case of a non-cash transaction 2, for example, a credit card transaction.

Further, in FIG. 3, the main control section 8a has a function of controlling each section, and also calculating transaction data input from the keyboard 6 and sending it to the data storage control section 9.

The data storage control unit 9 has a function of controlling storage and reading of data into and from a C-MO3 (complementary metal oxide semiconductor) memory 10, which is suitable for handling required rapid data processing.

The C-MOS memory 10 is a storage means for storing data calculated by the main control unit 8a, and is a volatile memory supported by a battery.

The key control unit 11 has a function of recognizing transaction data input from the keyboard 6 and sending it to the main control unit 8a.

The display control section 12 has a function of displaying transaction data and the like sent from the main control section 8a on the display 4.

The printer control section 13 causes the printer section 5 to print out transaction data and the like sent from the main control section 8a.

With such a configuration and function, data is transferred to the main control unit 8 by the operator inputting the keyboard 6.
The product number, product name, unit price, and operation instructions for the operator are displayed one by one on the display 4 according to commands from the main control unit 8a, and finally, the necessary calculation processing is performed by operating the input end button 6a. The total amount and change will be displayed.

As the input of transaction data progresses, the printer unit 5 prints a receipt and journal (not shown),
Finally, when the total amount etc. are printed, a receipt is issued from the receipt issuing port 5a.

Next, the cashier 17 opens and comes forward, allowing cash to be disbursed and disbursed.

When the transaction is completed, the transaction end button 6b is pressed, and the data for each transaction is calculated along with the total value, classification total, sales total, etc., and is sent to the C-MOS memory 10 and stored as a hard total. The contents of this hard total consist of various transactions such as cash transactions and credit transactions, totals by transaction type, and total sales amount, and are printed out, for example, at the time of settlement at the end of the day.

Further, data for each transaction is sent to the T/C 2, aggregated, and further sent to the computer center 3.

If the operator makes an operational error during this time, a warning message or the like is displayed on the display 4 so that the error in processing can be corrected.

Transaction data can also be entered by using a barcode reading device to read the barcode written on the packaging of the product, etc., instead of having the operator operate the keyboard 6, but the electronic register 1a can be used for either method. can.

However, according to this method, the C-MOS memory 10
Because of its fast access speed, it is suitable for the rapid data processing required, but as mentioned above, it is a volatile memory whose memory is maintained by battery support, so it is susceptible to software runaway.

■Inadvertent removal of the printed board unit by maintenance personnel in the event of a hardware failure.

If battery support is canceled due to such reasons, the memory contents will be destroyed, and the hard totals containing data for each important transaction in each of the electronic registers 1a to 1n will disappear.

When the hard total is deleted, it is necessary to go back to the journal and re-enter the transaction data at the time of failure recovery, which takes time and effort. Therefore, there is a drawback that maintenance personnel and the like must always pay attention to the presence or absence of battery support.

(d) Object of the Invention The object of the present invention is to solve the above-mentioned drawbacks, and to provide a data processing device capable of protecting the hard total against removal of battery support.

(131 Configuration of the Invention The present invention provides an input means into which transaction data is input, an arithmetic means for aggregating the transaction data inputted by the input means, and a memory for storing the aggregated data aggregated by the arithmetic means in parallel. volatile storage means and nonvolatile storage means,
and instruction means for instructing to transfer the aggregated data from the non-volatile storage means to the volatile storage means, and the transaction data processing device transfers the aggregated data to the volatile storage means transaction based on the instruction of the instruction means. By doing so, the above objective can be achieved.

That is, according to the present invention, a non-volatile storage means is provided, transaction data stored in the volatile storage means is stored in parallel in the non-volatile storage means, and battery support of the volatile storage means is released. The transaction data can be protected when the stored data is lost.

(f) Embodiment of the Invention An embodiment of the invention will be described below with reference to FIGS. 4 and 5. FIG. 4 is a block diagram showing an embodiment according to the present invention, and FIG. 5 is a flowchart of FIG. 4. The same reference numerals refer to the same objects throughout the design.

In FIG. 4, the main control section 8b has the functions of the main control section 8a described in the conventional example, and also transfers transaction data from C-M.
When stored in the OS memory 10, the C-MOS memory 10
A command to store all the data stored in the bubble memory 17 as backup data is sent to the data protection control section 15 and the bubble control section 16, and when the operator operates the backup button 14a, the data is stored in the bubble memory 17. backup data in C-
It has a function of sending a command to transfer to the MOS memory 10 to the data protection control section 15 and bubble control section 16.

The keyboard 14 has the functions of the keyboard 6 described in the conventional example, and also includes a backup button 14a.

The data protection control unit 15 has the functions of the data storage control unit 9 described in the conventional example, and also stores the data speed stored in the C-MOS memory 10 in the bubble memory 17 according to a command from the main control unit 8b. In addition, when the data in the C-MOS memory 10 is destroyed, the data backup amplifier controls the data stored in the bubble memory 17 to be returned to the C-MOS memory 10 again by operating the backup amplifier button 1.4a. have.

The bubble control unit 16 has a function of controlling storage and transmission of data to the bubble memory 17.

The bubble memory 17 is a non-volatile storage means whose stored data is updated for each transaction in order to back up the data stored in the C-MOS memory 10.

Since it has such a configuration and function, the hardware total backup method will be explained with reference to the flowchart in FIG.
Until the transaction data is stored as 0, the main control unit 8b checks whether the input end button 6a is pressed each time transaction data is input.

When the input end rainbow 6a is pressed, that is, each time the so-called registration button 6a for registering a single item is pressed, the transaction data is totaled and the cumulative total is calculated. Next, transaction data is supplied to the printer control section 13 to be printed on a receipt. At this point, it is checked whether or not a transaction end button 6b such as a total button has been pressed. If it has not been pressed, the process returns to the original routine, and if it has been pressed, the process moves to the next step.

By pressing the transaction end button 6b, the calculated total and cumulative value are printed out on the receipt.

Next, these transaction data are further accumulated and stored in the C-MOS memory 10 as a cumulative value of transactions up to that point (data already stored in the C-MOS memory 10). Once stored in the C-MOS memory 10, all stored data is sent to the bubble memory 17 and stored therein. This is repeated for each transaction, and the data in the bubble memory 17 is updated so that the same content as that in the C-MOC memory IO is always stored.

At the end of storage, it is checked whether a settlement button (not shown) has been pressed. If not pressed, return to the original routine.

When the settlement button is pressed at the end of the day, C-MO
All the hard totals stored in the S memory 10 are printed out on receipt paper, and the data stored in the C-MOS memory 10 is cleared.

The data stored in the bubble memory 17 is held as is until updated with the first transaction data the next day. That is, the contents of the C-MOS memory 10 start from a cleared state when the station is opened, and the value of the C-MOS memory IO is transferred as the value of the bubble memory 17, and the contents of the C-MOS memory 10 are cleared.
7, the content of the bubble memory 17 remains the previous day's cumulative transaction value until one transaction is completed after the opening of the market and the transaction end button 6b is pressed.

If the battery support is canceled and the hardware total in the C-MOS memory IJ10 disappears due to software runaway or replacement of the printed board unit due to a hardware failure, the failure is repaired. Thereafter, when the operator operates the bank up button 14a, the main control section 8b operates, reads out the hard total stored in the bubble memory 17, that is, the hard total of all the transactions that have already been completed, and - Transfer to the MOS memory 10 and store in the storage area of the C-MOS memory 10.

In this way, data storage speed during transaction processing is maintained,
Moreover, it is possible to protect the hard total up to the transaction immediately before the occurrence of the failure.

Therefore, there is no need for maintenance personnel or the like to pay special attention to the presence or absence of battery support.

Furthermore, when collecting the respective hard totals from a plurality of electronic registers 1a to 1n and totaling them at the T/C 2, the reliability of the data can be increased by using the hard totals protected by the bubble memory 17. .

If, for example, the electronic register 1n as a representative among the plurality of electronic registers la to 1n has a part of the function of the T/C 2 and has the function of totaling the hard total of the electronic registers 1a to 1n, bubbles may be generated. Of course, the data in the memory 17 can be used.

(g) As described in detail, according to the present invention, even if the data stored in the volatile storage means disappears, it can be restored using the data stored in the nonvolatile storage means. .

■In the event of a hardware failure, maintenance personnel can replace the printed board unit without having to be aware of the presence or absence of battery support.

(2) Even when data from multiple terminal devices is aggregated, the reliability of the data can be increased by using data stored in the non-volatile storage means.

There is an effect.
