Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a price lookup function of a plurality of electronic cash registers.

[Conventional technology]

One terminal controller to which a child cash register is connected has one PLU7 aisle for price lookup, which is accessed by multiple electronic cash registers.

[Problem that the invention seeks to solve]

If the terminal controller does not have storage for large PLU files that can be accessed quickly, the PLO7 file may be located on an external storage device, such as a floppy disk, which will slow down the price lookup process. This sometimes caused problems with cash register operations. Furthermore, in order to avoid this problem and to provide each register with a PLU file, a large-capacity, high-speed accessible storage device was required for each register.

Accordingly, an object of the present invention is to provide an inexpensive electronic cash register control system that enables high-speed processing.

[Means for solving problems]

According to the present invention, an electronic cash register has a medium-sized P
It is characterized by having a high-speed accessible storage device for LO files, distributing PLU file data among multiple electronic cash registers, and performing price lookup processing by communicating between each electronic cash register. A Seiko cash register control method is obtained.

In other words, the 'electronic character register control system of the present invention includes a means for storing a plurality of PLU records having at least information unique to a product, that is, a product code, a product name, and a unit price, and an arbitrary PLU record from this storage means. means for reading and writing.

A means for storing one PLU record, a means for inputting a product code, a means for storing the own cash register number unique to this electronic cash register, and classifying product codes by the number of digits and size. means for storing, for each product code group, a table in which electronic cash register numbers in which PLU records with product codes belonging to the product code group are stored are stored; A means of detecting the electronic cash register number in which the record is stored and other
A means for communicating with the child cash register, a means for creating commands to be sent to other electronic cash registers, a means for interpreting commands received from other electronic cash registers, and display and printing of product names, unit prices, etc. an electronic cash register having a means for inputting the deposit amount, the number of products, etc., and a means for performing processing such as totaling sales and calculating change for the PLU record stored according to the input data and product code. A price lookup function is achieved by connecting a plurality of electronic character registers, storing all different numbers in the cash register number storage means of each electronic cash register, and storing different PLU records in the PLU record storage means.

〔Example〕

Next, an embodiment of the present invention will be described with reference to the drawings.

Figures 1 and 2 show an electronic cash register (PO).
s) hardware configuration.

A central processing unit (CPU) 1 includes a communication interface 2, a keyboard 3, a barcode scanner 4 for inputting product codes, a printer 5, a display device 6, a ROM 7 that stores all the programs to be controlled by the CPU 1, and a RAM 8, a battery. A non-volatile memory 9 with backup and a cash register number setting dial 10 are connected. This POS is connected to controller 1 as shown in Figure 3.
Multiple connections are made to 1.

The controller 11 can access the FDl 2i and has the function of delivering data to each PO8.

All PLU records in FDl2 are divided in advance into the number of POS units and have a one-to-one correspondence with each PO8.
When loading a PLU record on a POS, the controller 11 passes the corresponding one to each PO8. As a result, different PI and U records are stored in the nonvolatile memory 9 of diameter PO8. In addition, the FDI 2 stores a correspondence table of product codes and electronic cash register numbers as shown in FIGS. 4 and 5, and the same table is loaded onto the non-volatile memory 9 of each PO 8. .

FIG. 6 to FIG. 1θ describe the flow of the CPU control program included in the OM7. The sales registration means m in FIG.
corresponds to steps [F] to [phase]. The sending command generating means i corresponds to steps 1 to 2, and the receiving command interpreting means j corresponds to steps 2 to Φ.

Referring to Figure 6, when the program starts, it first accepts instructions such as keyboard input.
Decide whether to load the Lσ record into the non-random memory 9, and if loading is specified, load it (■
, ■). Next, input from the keyboard 3 is accepted, and if there is an input, the number of pieces and total change are processed for that person's key data (■～■, ■～■), and when there is no input, Perform PLU processing 7.

Referring to FIG. 7, a request for inputting a product code is sent to the barcode scanner 4 (■). If there is an input, the PLU record will be processed one after another, and if there is a PLU record with the input product code, 1 display device 6
The product name and price are displayed on the printer 5, and the product name and price are printed on the printer 5 (0° [F]). If the PLU record does not exist, error processing (2) is performed for it and a product code input request is issued again. ■If the product code is not input, check whether communication data has been sent from another electronic cash register [stock], and if there is a received command, perform the received command interpretation process Ω, and then input the product code again. Find out if

Referring to FIG. 8, steps [F] ~ @ and ■, ■
This is a procedure for detecting a cash register number indicating in which electronic cash register the input product code is stored from the tables of FIGS. 4 and 5 stored in the nonvolatile memory 9.

It is expressed logically without using addresses.

First compare the product code length, then compare the minimum product code and maximum product code, extract the address where the corresponding cash register number is stored, and select the electronic cash register where the target PLU record is stored. Get a number. This number is compared with the number set on the dial 10, and if they are equal to 1, the target PLU record is present in its own cash register, and a read request is issued. If they are not equal, a read command is sent to the other electronic cash register (@, no) and the read data is waited for (■ to ■).

The process shown in FIG. 9 is to issue a PLO record read request to other electronic cash registers (@, ■) and return data in response to a read request received from another electronic cash register (Φ~). be.

Referring to FIG. 10, which shows the processing of data received from other electronic cash registers, this processing is to check whether the data is a reply to a read request issued from the own cash register, and if so, and if a PLU record has been found. For example, data is placed in the RAM 8 and a PLU record is stored (corresponding to C). If it is not reply data, it is a read request from the other child cache register, so read the PLU record from memory 9, and if it is found, send a record sending command (o, ■), if not found, send a message to that effect. Do (■, ■).

〔Effect of the invention〕

As explained above, the present invention has the effect of speeding up price lookup processing and reducing cost.
