The present invention relates to a POS terminal device that prints on a receipt and transmits the input code to the device.

[Conventional technology]

In order to streamline store operations by centrally managing information at the point of sale of products, computer-based store management systems called POS systems have recently become widespread.

In this case, the system configuration includes multiple terminal devices set for each sales floor or store, a central control device that connects each terminal device, and a central control device that controls each terminal device, and a central control device that controls each terminal device, and a central control device that controls each terminal device. It has a computer for processing and a product file in which product information is stored and is connected to a central control unit.

However, the terminal device of the above-mentioned POS system is generally equipped with a barcode reading section, a receipt printing section, and a data transmitting/receiving section.The product code read by the scanner in the reading section is sent to the central control device, The controller refers to the product file and prints the returned product name and price information on a receipt to conduct transactions with the customer.

[Problem that the invention seeks to solve]

As mentioned above, in the conventional system in which a large number of terminal devices are connected to one central control unit, barcodes attached to products can be read at extremely high speed; Since it is necessary to communicate data with the equipment, if a large number of terminal devices are installed, the data transmission time for each terminal device is limited, reducing the processing efficiency of the entire system and hindering the speeding up of checker work. It had been.

In order to solve the above-mentioned conventional problems, the present invention provides the POS terminal device itself with an input code processing function, and prioritizes the receipt issuing task while temporarily suspending the sending of data to the central control device. The aim is to provide a new POS terminal device that can handle multiple tasks.

[Means for solving problems]

In the figure, there is a barcode reading unit connected to a central control unit that reads barcodes added to products and inputs an input code corresponding to the read barcode, and a barcode reading unit that is connected to a central control unit and that inputs an input code corresponding to the read barcode, and a barcode reading unit that is connected to a central control unit and that inputs an input code corresponding to the read barcode, and a barcode reading unit that is connected to a central control unit and that inputs an input code corresponding to the read barcode. It includes a printing section for printing, and a transmitting/receiving section for transmitting at least the input code input from the bar code reading section, and transmitting the input code input from the bar code reading section to the central control unit via the transmitting/receiving section. POS to send
In the terminal device, there is a product information reference memory section that generates receipt print data including price information corresponding to the input code read by the barcode reader, and an input code input from the barcode reader and sent to the central control device. It is attached with a buffer memory section that temporarily stores the information.

[Effect]

In the present invention, with the above-described configuration, the input code input from the barcode reading section 11 is written into the buffer memory section 15, and the receipt print data corresponding to the input code is read from the product information reference memory section 14 and printed. Part 12
The central controller 20 transmits the input code by supplying the input code to the product information reference memory unit 14 and reading it from the product information reference memory unit 14 in parallel with writing the input code to the buffer memory unit 15 so as to print it on the receipt. It is possible to find and send a message when the central control unit is free, and to quickly issue a receipt to give to a customer.

〔Example〕

The present invention will be explained below with reference to the figures.

That is, the figure is a block diagram schematically showing the configuration of an example of a POS system including POS terminal devices to which the present invention is applied, in which a plurality of terminal devices 10 are connected to a computer 30 via a central control device 20. It's taking shape. Each terminal device 10 has a conventional barcode reading section 11, a receipt printing section 12, and a data transmitting/receiving section 13, as well as a reference memory section 14 and a buffer memory section 15. The reference memory unit 14 is a memory that stores the product name and price information corresponding to the input code of each product read by the scanner of the barcode reading unit 11. After referring to the input code, the reference memory unit 14 stores the corresponding product information on the receipt. It is supplied to the printing section 12.

Specifically, the checker operator causes the scanner of the barcode reading section 11 to read the barcode attached to the product. The input code read by the barcode reading section 11 is supplied to a reference memory section 14 and a buffer memory section 15.
When the input code is supplied to the reference memory section 14, the reference memory section 14 searches the information stored in the reference memory section 14 for product name and price information corresponding to the supplied input code. The searched and extracted product name and price information are supplied to the receipt printing unit 12 as receipt printing data. The receipt printing unit 12 to which the receipt printing data has been supplied prints the product name and price information on the receipt based on the receipt printing data.

Further, the input code supplied to the buffer memory unit 15 is stored until the storage capacity reaches a predetermined amount or the central control unit 20 becomes empty.

Note that the contents of this reference memory section 14 are as follows:
It is loaded from the product file 21 of the central control device 20 and can be modified and updated at any time. Further, the reference memory section 14 does not necessarily need a capacity sufficient to store information on all products; in some cases, it may store only product information that is frequently searched or referenced, and the rest is stored in the central control unit. It is also possible to share the product file 21 on the side.

Reference memory 1 that stores product information as described above
By adding 4, each terminal device itself has an input code processing function, and it becomes possible to issue a receipt clearly indicating the product name without making an inquiry to the central control device 20. On the other hand, for sending the input codes to the central control unit 20 for sales aggregation, etc., the input codes are stored in the buffer memory section 15 so as to be transferred all at once using a separate free time. The storage capacity of the buffer memory section 15 in this case can be appropriately selected depending on the number of products handled per unit time, the time interval at which data can be sent, and the like.

〔effect〕

As described above, according to the present invention, input codes are referenced by the POS terminal device itself, which reduces the load on the central control device, and allows the POS terminal device to perform check operations independently. In parallel with this check operation, the input code is sent to the central control device, so the data obtained in the check operation can be printed on the receipt, and the receipt can be issued quickly, allowing the customer to There will be no need to repeat.

Therefore, the flexibility of the POS system as a whole is improved, processing efficiency can be improved, and service to customers is also improved.
