Description

How to Simultaneously Process and Display Multiple Transactions in a Cash Register

The present invention relates to a method of simultaneously processing and displaying multiple transactions of a cash register. More particularly, the present invention relates to a single cash register, which processes one or more transactions at the same time and displays and displays the results of the processing. A method of simultaneously processing and displaying multiple transactions of a cash register.

In general, a cash register refers to a device used to facilitate information management by processing and informing a user of various data associated with the sale of a product. It ranges from point of sales (POS) systems that can be managed. Hereinafter, in the present specification, the term ECR (Electronic Cash Register), which means an electronic cash register controlled by a microcomputer, is used as a broad concept including a low-end cash register to a POS terminal.

1 is a system block diagram of a general cash register. As shown in the figure, a general ECR system kisses the key input unit 20 and the key input unit 20 generating various key codes for mode designation and money registration, and changes the mode of the ECR according to the received key code. The central processing unit 10 for designating and performing various functions in the designated mode, the ROM 30 storing a program for operating the system, and the RAM 40 storing various data generated during a program or a transaction set by the user. ), A display unit 50 for displaying various information related to a transaction under the control of the central processing unit 10, and a printer 60 and a system for issuing documents for customer receipts and various processing results under the control of the central processing unit 10. It supplies power to the whole, and is provided with a power supply unit 70 for preserving data stored in the RAM 40 by supplying power by the backup battery in case of power failure. Eojinda.

A conventional cash register as described above can process and display only one transaction at a time. That is, since two or more transactions cannot be processed at the same time, conventionally, when there are several customers, the transaction processing of the next customer can be started after the transaction processing of one customer is completed in order. For example, if a guest wants to purchase another item while processing a registration transaction, the client waits for the customer to pick up the item and then closes the guest's registration transaction with the imported item before starting the next customer's transaction. Or cancel the transaction so far and process the transaction of the next guest. Due to this, there is an economic problem that the customers have to wait with a heavy load and the store side should have several cash registers to eliminate such inconvenience.

In order to solve this problem, there is a function that can process a number of transactions like the table management function, but this table management function can also process transactions of other tables after intermediate processing after each table processing. It is limited to simple functions for managing a table such as a restaurant, so there is a problem that it is not suitable for convenient use in various types of businesses.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and simultaneously handles multiple transactions of a cash register, which makes it possible to expedite transaction processing by simultaneously processing one or more transactions with one cash register and displaying and displaying the results of the processing. And a display method.

Simultaneous processing and display of multiple transactions of the cash register of the present invention to achieve the above-mentioned object is to receive a number of transactions to be processed simultaneously in the program mode of the transaction buffer to temporarily store the transaction details of each transaction in accordance with the input number Setting a starting point; Switching to a display of a corresponding transaction screen and moving the address of the transaction buffer to a transaction buffer address of the corresponding transaction when a command to perform another transaction is received while performing a transaction of the screen displayed in the registration mode; Displaying registration data on the transaction screen and storing the registration data in the corresponding transaction buffer; If a registration end command is received, printing the entire transaction details of the transaction screen and updating the settlement area with the transaction details; And initializing the transaction screen and the transaction buffer. Further, when the transaction screen is divided by the number of transactions received in the transaction number setting step, the screen is initialized, and a command to perform a transaction other than the transaction being performed in the registration mode is received, the cursor is moved to the corresponding transaction screen and the transaction screen is displayed. It is characterized by that it can inform that it is running.

Hereinafter, with reference to the accompanying drawings will be described in detail with respect to the multiple transaction simultaneous processing and display method of the cash register according to a preferred embodiment of the present invention.

2 is an exemplary diagram showing a key configuration of a key input unit to which the multiple transaction display method of the cash register of the present invention is applied. As shown in the figure, the key configuration of the key input unit 20 to which the method of the present invention is applied is a mode switch 21 used to designate a desired operation mode among various operation modes of the ECR, and various functions provided in the ECR. A function key group 23 used to execute a desired function among the items, an item key group 25 used to designate a desired item, and a numeric key group 27 used to input a price or a corresponding numeric code of various items. Is done. In the above-described function key group 23, the 'transaction number setting' key 23a used when setting the number of transactions in the method of the present invention, and the 'transaction' key used when switching to the registration mode of the transaction to be processed 23b and the 'settlement' key 23c necessary for settlement may be included.

In the above-described configuration, the general operation modes of the ECR include a program mode, which is a mode used to change the program contents of various files and tables used in the ECR, a registration mode that registers and processes various transaction information generated at the point of sale. There are a settlement mode, a check mode and a stop mode that can be used to settle the transaction information stored in the), and if the settlement mode is executed, the transaction details stored from the previous settlement point are deleted from the corresponding area of the RAM 40. .

3 is a flowchart illustrating a method of simultaneously processing and displaying multiple transactions of the cash register according to the present invention. In the present embodiment, description will be given by dividing the screen by the number of transactions as an example. As shown in this figure, first in step S10, it is determined whether the operation mode of the ECR is switched to the program mode which is a mode in which the user can set the desired number of transactions (or the number of transaction screens). As a result of the determination in step S10, if the operation mode of the ECR is a program mode, the process proceeds to step S12 and input of the 'transaction number setting' key 23a for setting the number of transactions (or number of transaction screens) desired by the user. Determine if there is. If there is no input of the 'transaction number setting' key 23a as a result of the determination in step S12, the flow proceeds to step S13 to perform a function of a corresponding program mode, and input of the 'transaction number setting' key 23a. If yes, the flow advances to step S14 to determine whether the transaction buffer is in use. If it is determined in step S14 that the transaction buffer is in use, the process proceeds to step S15 for error processing. If the transaction buffer is not in use, the process proceeds to step S16 to receive the number of transactions. At this time, a method of inputting the number of transactions is a method of inputting a numeric key corresponding to the desired number of transactions after the input of the 'transaction number setting' key 23a. Subsequently, in step S18, the transaction buffer is divided by the number of transactions input in step S16 to set the maximum quota of one transaction and the start address of each transaction buffer. For example, if the transaction buffer is from 1,000 to 2,000 and the transaction number 4 is input, the quota of one transaction is 250 bytes, and the starting address of each transaction buffer is 1,000, 1,250, 1,500, and 1,750. In the next step S20, the transaction screen is initialized by dividing the transaction screen by the number of transactions received in the step S16.

After setting the number of transactions in the program mode as described above, in step S30, while the customer's transaction is processed by switching the operation mode of the ECR to the registration mode, in step S32, input of a transaction number for processing another transaction is performed. Determine if there is. At this time, a method of inputting a transaction number includes a method of inputting a 'trade' key 23b and a numeric key corresponding to a transaction number desired for a transaction. For example, if a situation in which transaction 4 needs to be registered during the registration process of transaction 2 occurs, the 'key' key 23b and the numeric key 4 are simultaneously pressed or the number key 4 after the input of the 'trade' key 23b. Switch to Transaction 4 by pressing. If there is no input of the transaction number as a result of the determination in step S32, the registration processing of the transaction (transaction 2) being performed is continued. In step S36, the caption transaction 4 is flashed to indicate that transaction 4 is being performed. In the initial screen when the registration mode is switched, the cursor is in transaction 1 and the subtitle transaction 1 is flashed. In a next step S38, the address of the transaction buffer is moved from transaction 2-3 to transaction 4-3.

After moving the execution operation to transaction 4 to perform a transaction as described above, in step S40, it is determined whether there is an input of a registration function key such as an item key, a discount key, and a premium key. If there is an input of a registration function key, for example, an item 9 key, in step S40, the flow proceeds to step S42 to display information corresponding to item 9, and in the next step S44, it corresponds to item 9. Information stored in the corresponding transaction buffer (Transaction 4-3). In step S46, the address of the transaction buffer is increased by one (transaction 4-4).

In step S50, it is determined whether there is an input of a registration end key such as a subtotal key, a sum key, or a cash key to end the transaction 4 currently in operation. As a result of the determination in step S50, if there is no input of the registration end key, the process proceeds to step S51 to perform a corresponding function. If there is an input of the registration end key, the process proceeds to step S52 and the entire transaction 4 is performed. The transaction details are printed, and in step S54, the settlement area is updated with the transaction details printed in step S52. In the next step S56, the screen of transaction 4 is initialized, and in step S58, all the data in the transaction 4 buffer which has completed the transaction are deleted.

In step S60, it is determined whether the operation mode of the ECR is switched to the settlement mode, which is a mode for settlement of transaction details of the transaction buffer. If it is determined in step S60 that the operation mode is not the settlement mode, the operation proceeds to step S61 to perform a function of the corresponding mode. If the operation mode is the settlement mode, the operation proceeds to step S62 to determine the transaction buffer. It is determined whether there is an input of the 'setting' key 23c to settle the data. If there is no input of the 'setting' key 23c as a result of the determination in step S62, the flow proceeds to step S63 to perform a function of the corresponding settlement mode, and if there is an input of the 'setting' key 23c Proceeding to step S64, it is determined whether the transaction buffer is in use. If it is determined in step S64 that the transaction buffer is not in use, the process proceeds to step S70 to perform settlement processing. If the transaction buffer is in use, proceeds to step S66 to delete data in the transaction buffer. Judge. In the case of deleting the determination result data of step S66, the process proceeds to step S68 to delete the data, and then proceeds to step S70 to perform the settlement process, and if the data is not deleted, step S70 immediately. Proceeds to perform the settlement process.
