Abstract

The present invention relates to a product information and sales clerk management method, a conventional electronic cash register has managed the information and inventory management or sales government of the goods using EPROM or RAM for the information about the goods or the management of the inventory items. In this case, it is easy to record information due to the characteristics of parts, but it is difficult to erase when wrong information is stored, and when RAM is used, input data is erased when the power supply is turned off.

In order to solve this problem, by adding an EEPROM device in the cash register, after selling the product in a store or a business, reducing the quantity of the product sold in the existing product holding quantity and storing the quantity in the EEPROM; Comparing and comparing the quantity of the commodity of the commodity with the quantity of the existing commodity; and, if the quantity of commodity sold in the comparing and determining process is greater than the existing quantity, outputting the required stock through the display unit, and information on the commodity. If the information is about the store clerk, all information about the store clerk is stored and managed in EEPROM. By managing the product and the clerk, the clerk or manager of the store or store can check the information or stock of the product at any time and respond quickly. Has an effect.

Description

How to manage product information

The present invention relates to a product information and salesman management method, and more particularly to providing software for attaching an EEPROM to an electronic cash register to record and change information about products and clerks sold in stores or stores at any time. It is about.

In general, the cash registers in use are installed in public places and narrow shops that handle cash for sales calculation or tax calculation, such as in department stores or convenience stores.

Such a cash register is provided with various functions for calculating and selling a price after selling a product.

The configuration and operation of such a cash register will be described in more detail with reference to the drawings provided.

1 is a circuit block diagram showing an operation according to the configuration of a cash register generally used in the prior art.

As shown, a central processing unit (hereinafter referred to as a CPU) 100 for controlling the overall operation of the cash register, and a ROM (ROM) 140 for providing various control programs and initial data to the CPU 100. And a memory device (RAM) 150 for storing information such as a unit price for each item for sales activity, information such as a sale amount generated from the sales activity, and various types of information generated from the cash register in the form of characters. Display unit 110 for, a small printer 120 for issuing a receipt for the sales history, and check the time to recognize the sold time and date, or the clock chip 160 for sales point management, and various Comprised of a keyboard 130 having a plurality of keys for inputting commands and data, the command or data input by the operation of the keys configured on the keyboard 130 is controlled by the CPU 100. Stored at 140) It is processed according to the program. In this process, the cash register operates and inputs and outputs data stored in the memory device 150 according to a user's needs. The result processed according to this process is output to the printer 120 or the display unit 110.

Conventional electronic cash registers operating in the above-described configuration have managed product information and inventory management or sales information using EPROM or RAM to manage product information or inventory items.

However, when using EPROM, it is easy to record information due to the characteristics of parts, but it is difficult to correct it when wrong information is stored.

In addition, when the RAM is used, there is a problem in that power must be continuously supplied due to a problem that the input data is erased when the power supply is turned off. Therefore, there is a problem that a lot of power is consumed.

Accordingly, an object of the present invention is to provide a method for managing information on merchandise and clerks by adding an EEPROM unit in a cash register in order to solve the above-described problems.

In order to achieve the above object, the process of reducing the quantity of the product sold from the existing product possession quantity after selling the product and storing the quantity in the EEPROM, the quantity of the product of the sold product and the quantity of the existing product Comparing the process, and if the quantity of goods sold in the process of comparing and comparing the existing quantity, outputting the required inventory through the display device, and if the information is not about the goods but about the salesperson, It is characterized by the process of storing all information in EEPROM.

2 is a circuit block diagram constructed in accordance with the present invention, as shown.

Central processing unit (hereinafter referred to as CPU) 10 for controlling the overall operation required for the operation of the electronic cash register, for inputting various commands and data, and for inputting information about products and clerks that change from time to time; A keyboard 20 composed of a plurality of keys, an EPROM 30 providing a system program and data for operating the CPU 10, and information such as a unit price per item for selling a product during system operation, or after the product is sold. RAM (40) for temporarily storing data on sales amount, EEPROM unit (50) for storing product information and sales information, and information for sales clerk management and inventory management, which frequently change, and the CPU ( The display device unit 60 reads out the data stored in the EEPROM unit 50 under the control of 10) and displays the data according to the user's needs, and also for printing. It consists of a printer (70).

An operation according to such a configuration will be described with reference to the flowchart of FIG. 3.

When the power of the cash register is turned on (S100) for information and management of the goods, the system initializes all the systems of the cash register (S110), and then all information about the goods currently held, that is, the quantity of the goods and The company name and phone number will be registered (S120).

As such, when all the information about the current product and the information about the clerk are registered, the clerk will sell the merchandise (S130).

After the product is sold, the amount of the sold product is reduced by the amount of the sold product from the existing product holding amount and is stored in the EEPROM unit 50 together with the current inventory (S140).

As described above, the sales quantity stored in the EEPROM unit 50 is judged to be compared with the quantity held by the user (S150). Since there is no article, information about a phone number and a company name of the article is output through the display apparatus 60 or the printer 70 under the control of the CPU 10.

The clerk or manager of the shop or store checks the contents output through the display apparatus 60 or the printer 70 in this process to cope quickly.

In addition, if it is not the sale of goods or information about the product or the information about the clerk (S170), if the product information sells and manages the product (S180), if the information about the clerk, the attendance and personal information of the clerk and all Frequently, by inputting the information into the EEPROM unit 50 and storing (S190), it is possible to quickly information about the clerk.

Therefore, the effect of the present invention operating in the above configuration is that the clerk or manager of the store or store using the cash register can check the information on the product through the display unit or printer, and the clerk or manager can The information on can be changed and stored as needed.

In addition, by storing the quantity of goods sold in the EEPROM to compare the current quantity held and the quantity sold, it is possible to check the current stock quantity through a display device or a printer, so that the response can be promptly responded. Has
