Abstract

PURPOSE:To increase a processing speed and to issue a receipt, etc., easy to see by transmitting the sales data for one transaction portion read until the registration completion of one transaction portion in a lump without transmitting the sales data to the title sales data processor whenever the sales data are read. CONSTITUTION:In an electronic cash register (ECR) equipped with a hand scanner, registration is executed in accordance with commodities. Here, the sales data are not transmitted to a sales data processor 2 whenever the sales data are read by a reader 1, but the sales data for one transaction portion read until the registration completion of one transaction portion are transmitted in a lump. Thus, the registering processing, etc., can be promptly executed, and since the contents of the data can be corrected before the transmission of the sales data, when the correction contents are not printed on the receipt, etc., the receipt, etc., easy to see can be issued.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a data processing device for electronic cash registers and the like that is equipped with a reading device for optically reading sales data.

[Prior art] In recent years, this type of electronic cash register (ECR)
The barcode (product code) from the product label, etc.
A device equipped with a hand scanner that optically reads the information has been developed and put into practical use.

That is, in an ECR equipped with a hand scanner, each time a product code is read using the hand scanner, the product code is transferred to the ECR side via a cable, and thereby the ECR
On the CR side, each product is registered based on the product code, that is, the total sales for each corresponding product in the product file is updated, and the sales data is printed on a receipt or the like.

[Problems to be Solved by the Invention] However, transferring the product code to the ECR and registering each product each time the product code is read using a hand scanner slows down the processing speed and increases customer waiting time. In addition to the longer time, when a correction operation is performed, the state of the correction operation is printed directly on the receipt, which has the disadvantage that the printed content on the receipt becomes complicated and difficult to read.

An object of the present invention is to significantly improve the processing speed of product-based registration, etc., and to issue easy-to-read receipts.

[Means to solve the problem] The means of this invention are as follows.

The reading device l (see the functional block diagram in Figure 1, the same applies hereinafter) is a barcode reader, etc. that optically reads sales data (product code, etc.) from a product label, etc., and transmits optical signals, radio waves, etc. The transmission and reception of data to and from a sales data processing device 2 such as an ECR as a medium is executed repeatedly.

This reading device 1 includes a data holding means 1-1 and a specifying means 1.
-2, a transmitting means 1-3 is provided. Here, the data holding means 1-1 is a random access memory or the like that stores and holds the read sales data. Also, specifying means 1-
2 is a cash key or the like that specifies the end of registration of one transaction. Further, when the specifying means 1-2 specifies the end of registration for five transactions, the transmitting means 1-3 transmits the sales data for one transaction stored in the data holding means 1-1 to the sales data processing device. Send to 2.

The sales-L data processing device 2 receives sales data transmitted by optical signals or the like from the transmitting means 1-3, and starts executing predetermined processing, such as product-specific registration processing, based on this sales data.

[Made by ITJ] The operation of the means of this invention is as follows.

Now, let us take as an example a barcode reader (hand scanner) as the reading device f and an ECR as the sales data processing device 2, and assume that product-specific registration is performed in this ECR equipped with a hand scanner.

In this case, the barcode (
When the product code) is scanned by the reading device 1, the reading bag 91 optically reads the product code, and also transfers the read product code to the data holding means 1-1 for storage and storage.

In this way, each time a product label, etc. is scanned using the reading device 1, the product code read is stored in the data holding means 1.
-1 is stored and held sequentially.

When the registration work for -transactions (for example, -customer) is completed and the specification means 1-2 specifies the end of registration for one transaction, the transmission means 1-3 stores the information in the data storage means 1-1. The product code for one transaction is read out, converted into an optical signal, etc., and transmitted to the sales data processing device 2.

As a result, the sales data processing device 2 updates the sales total for each corresponding product in the product file based on the transmitted product code, starts a printing operation, and issues a receipt or the like.

Therefore, the sales data is not sent to the sales data processing device 2 every time the sales data is read by the reading device 1, but the sales data for the five transactions that have been read up to that point are sent all at once when the registration of the transactions is completed. This makes it possible to speed up the registration process, as well as to correct the sales data before sending it.If the corrections are not printed on receipts, etc., it is possible to issue easy-to-read receipts, etc. becomes possible.

-20 is configured to store the character, unit price, number of sold items, and sales amount in correspondence with the product code, as well as the number of items in stock, in the same way as the FLU file provided in a normal ECR.

Next, the operation of this embodiment will be explained.

Now, when performing a product-specific registration operation, in this embodiment, the hand scanner 11 is placed on the controller 13 and is performed using the keyboard 11-2 on the hand scanner 11 according to the normal key operation procedure. This can also be done by manually scanning a product label, etc. When the power is turned on, the hand scanner 11 executes the operation according to the flowchart shown in FIG.

First, check whether the product label, etc. is being scanned (Step A1).
) or a key operation on the keyboard 11-2 (step A2), and is in a standby state until scanning or key operation is performed.

In this state, when a key operation is performed, key manual processing (step A3) is executed in accordance with the key operation, and then the type of operated key, that is, whether or not it is a close key FK is determined (step A4). FL to enter code
When the U key (not shown) or the like is operated, normal registration calculations (such as subtotal calculations) are executed (step A5).
), PLU file 1 corresponding to the input product code
The number of sold items in the FLU file 11-21 is updated (step A6), and the process returns to step AI, where the above process is repeated every time the FLU code is entered, and the number of sold items in the FLU file 11-21 is updated. It is being done.

Furthermore, if the PLU code is optically read by scanning a product label, etc., this is detected in step A1 and the process proceeds to step All, in which the FLU file 11-21 is searched based on the read FLU code, The unit price corresponding to the applicable code is read from the FLU file 11-21, normal registration calculations (subtotal calculation, etc.) are executed (step A12), and the number of sold units corresponding to the applicable code in the FLU file 11-21 is updated. (step A13), and then returns to step AI, and as a result of repeating the above operation every time scanning is performed, FL
The number of sales in the U file 11-21 is updated.

- When the closing key FK is operated at the end of transaction registration, this is detected in step A4 and step A7
Proceed to and execute finalization calculations (change calculation, etc.). Then, after creating data to be transmitted to the controller 13 (step A8) and transmitting it from the transmitter 11-18 (step A9), the PLO file 11-21 is
All sales numbers corresponding to each product in the list are cleared, and subtotal data, etc. are also cleared (step Al0).

Figure 8 shows the transmission format of the transmission data in this case, and this transmission data includes the start code, drawer open command, FLU code..., subtotal, etc.
It consists of a transaction code, a receipt print command, and an end code. The FLU code in this case is that the number of sales in FLU file 11-021 is "1".
'', that is, all other product codes except the product code whose sales volume corresponds to rOJ. In other words, every time the registration of a transaction is completed, the number of sold items in the PLU file 11-21 is all cleared, so the fact that the number of sold items is equal to or greater than rlJ indicates that the product was registered in the current transaction. ing.

When the data is transmitted from the hand scanner 11 in this way, the controller 13 executes the operation according to the flowchart in FIG. In this state, when data is transmitted from the /\ door scanner 11, this is detected in step B1 and the process proceeds to step B2, where it is checked whether a drawer open command has been received. If a drawer open command is received here, the process advances to step B3, where a drive signal is given to the drawer main body 12 to open the drawer, and step B1
Return to If a receipt print command is received, this is detected in step B4 and step B5 is executed.
, the FLU file 13-20 is searched based on the received FLU code, and arithmetic processing is performed to update the sales quantity and sales amount in the PLO file 13-20 corresponding to the corresponding code, as well as update the inventory quantity. After performing this, the calculation results are transferred to the PLU file 13-20 and the number of sales, sales amount, and inventory quantity corresponding to the corresponding code are updated (step B6).Then, the process proceeds to step B7, where the printer 14 A drive signal is applied to the printer to print out sales data on receipts and journals, and the process returns to step B1.

Product-specific registration is performed based on the data transmitted from the hand scanner 11 in this manner. In this case, the CPU
13-11 is a transaction-specific file in RAMI 3-17 (
(not shown) is also registered by transaction, and various registration processes (registration process by person in charge, etc.) are performed as necessary.

1. In the above embodiment, when a report print command is received, product-specific registration is executed, but some customers do not need to issue a receipt, so in such a case, After performing separate registration, etc., check whether there is a receipt print command, and if there is no print command, do not issue a receipt.

Further, in the above embodiment, an optical signal or the like is used as a transmission medium between the hand scanner 11 and the controller 13, but it is of course possible to connect the two through a cable and transfer them all at once.

[Effects of the Invention] This invention does not transmit sales data to the sales data processing device every time sales data is read, but transmits the sales data for the five transactions read so far at once when transaction registration is completed. This makes it possible to use free time such as cash transfers and other tasks to register and print items by product, greatly improving processing speed. Since corrections can be made, it is possible to issue receipts that are easy to read by not printing the corrected information on receipts. Furthermore, since a plurality of reading devices can be installed in one sales data processing device, more reading devices can be added during times of congestion.
