Note that in other POS systems where the host computer 24 is not provided, the stored contents of the PLU file 23 are printed by a printer included in the master ECR 21.

[Problems to be solved by the invention] As mentioned above, the PLU in the conventional POS system
Among report issuance methods, methods that use a host computer have the problem of high equipment costs, and methods that use a master ECR require a long time to print out all the data. There was a problem.

Therefore, a primary objective of the present invention is to provide a transaction processing device that is inexpensive and capable of issuing PLU reports in a short period of time.

[Means for Solving the Problems] The master device of the transaction processing device according to the present invention includes a report issue instruction means for instructing each of a plurality of satellite devices to issue a report, and the report issue instruction means. A counting means for determining whether or not multiple satellite devices are capable of issuing reports in response to instructions from the controller, and counting the number of satellite devices capable of issuing reports, and a storage area for transaction files based on the count of the counting means. Print area notification means divides and allocates an area to be printed for each satellite device, and notifies information indicating the area, and each of the plurality of satellite devices a report issuing means for issuing a report based on the
The report issuing control means reads the stored contents from the area to be printed in the transaction file based on the notification contents by the print area notification means of the master device, and causes the report issuing means to issue a report.

[Operation] When the master device of the transaction processing device according to the present invention instructs each of the plurality of satellite devices to issue a report, the master device determines whether each satellite device is capable of issuing a report and issues the report. The number of possible devices is counted, and based on the counted value, the transaction file storage area is divided and allocated to each satellite device, and information indicating the allocated area is notified to each satellite device. When each satellite device receives the notification, it reads the stored contents from the transaction file based on the notification contents and issues a report.

[Embodiments of the invention] FIG. 1 is a functional block diagram showing the concept of the invention.

In Figure 1, there is one master ECR in the store's sales floor.

Determine whether or not each satellite ECR2 is in a report issuing state, count the number of reports capable of issuing reports, divide the storage area of the PLO file 31 based on the counted value, and allocate it to each satellite ECR2. It has a function of notifying each satellite ECR 2 of information indicating the storage area. Based on the information notified from the master ECRI, each satellite ECR 2 reads data corresponding to the notification information from the PLU file 31 and writes the PLU report 4.
will be printed and issued. Since each satellite ECR 2 reads data from its individually allocated storage area and prints it all at once, a PLU report can be issued in a short time. Note that, as shown in FIG. 1, if a print range is also allocated to the master ECRI and the PLU report is printed, the print range will be reduced by that amount, and the report issuance time will be shortened.

FIG. 2 is a schematic block diagram showing the electrical configuration of the satellite ECR 2 shown in FIG. 1, and FIG. 3 is a diagram showing the key arrangement of the keyboard shown in FIG. 2.

The electrical configuration of the master ECRI is that of the satellite EcR.
Since the electrical configuration is the same as No. 2, the explanation will be omitted.

FIG. 4 is an illustrative diagram showing the PLU file shown in FIG. 1. In FIG. 4, a large number of PLU records are stored in the PLU file 31.

Each PLU record includes a PLU code, unit price data, total sales amount data, and sales quantity data.

The PLU code and unit price data are preset data, and the total sales amount data and sales quantity data are data that are updated every time the product is sold.

Next, the registration processing operation in the REG mode will be described with reference to FIGS. 1 to 4.

The operator first switches the changeover switch 61 to the REG mode. Next, for each product purchased by the customer, the operator uses a scanner (not shown) to read the barcode attached to the product, or manually enters the PLU code from the numeric keypad 62, and then enters the department code from the department key 63. Manpower. CPU5 is based on the manually generated PLU code.
Search the PLO file 31, read unit price data from the record of the corresponding PLU code, display it on the display 7, add the unit price data to an adder (not shown) for each department, and read the unit price data from the record of the corresponding PLU code. Update the total sales amount data and sales quantity data of the PLU code.

When the input of PLU codes for all products is completed, the operator operates the subtotal key 64. In response to this, the CPU 5 calculates the total sum of the adders and displays it on the display 7.

The customer looks at the display on the display 7, prepares the payment amount, and hands it to the operator. The operator inputs the payment amount using the numeric keypad 62 and operates the current/total key 65. Accordingly,
The CPU 5 calculates the change, displays it on the display 7, and opens the cash drawer 9. The operator takes out change from the cash drawer 9 and hands it to the customer. This completes one transaction. In this way, the PLU file 31 whose stored contents have been updated for each registration process is subjected to aggregation processing, for example, after the day's business ends.

The figure is a flow diagram for explaining the operation check operation of the satellite ECH, and FIG.
FIG. 3 is a flow diagram for explaining the PLU report issuing operation of CR.

Next, the operation of one embodiment of the present invention will be described with reference to FIGS. 1 to 7.

When performing aggregation processing, both master ECR1 and satellite ECR2 are set to, for example, Z mode. As shown in FIG. 5, first, an operator issues a report issue command to the master ECR 1. The manual method for issuing this report is performed, for example, by manually inputting a code representing this command, and then pressing a predetermined function key. Subsequently, it is determined whether each satellite ECR2 is being processed. This determination is made as follows. First, as shown in FIG. 6, an operation check command is sent from the master ECRI to each satellite ECR2. In response to receiving this operation check command, the CPU 5 of each satellite ECR 2 checks whether its own terminal is in process of calculation or input, and if it is not in process, resets the status flag to 0; , if processing is in progress, set the status flag to 1.

Next, the CPU5 of the satellite ECR2 is the master ECR
The message shown in FIG. 6A is sent back to I to report the operation status. This reply message includes a response command indicating that it is a reply message, and the satellite E
It includes the terminal number of the CR and the above-mentioned status flag. In this way, when reply messages from all satellite ECR2s are sent to the master ECRI, it is determined whether or not there is a satellite ECR2 currently being processed based on the status flag. Here, as shown in FIG. 5, if there is a satellite ECR2 being processed, its terminal number is displayed. Furthermore, if there is a satellite ECR2 in which an error has occurred, its terminal number is also displayed. Master ECRI
The operator looks at the display and chooses whether to continue or cancel the operation. If the operator chooses to proceed and all satellite ECs
If R2 is not being processed, then the number of terminals that can output reports is determined.

Subsequently, the storage area of the PLU file 31 is divided by the number of terminals capable of outputting the report, and the number of PLU records to be allocated to each terminal device is determined. Subsequently, the PLU code of the range to be printed is determined for each terminal device. For example, suppose there are 100 PLU records, and satellite ECR2 that can issue reports
Assuming that there are three PLO records, the 1st to 33rd PLO records are assigned to the satellite ECR2 of the 1st [I], and the 34th to 66th PLO records are assigned to the second satellite ECR2. Records are allocated, and the 67th to 100th PLU records are allocated to the third satellite ECR2. Subsequently, a report output command is transmitted to each satellite ECR2. As shown in FIG. 5A, this report output command includes a code indicating that it is a report output command, and a start code and an end code indicating the reading range of the PLU file 31.

As shown in FIG. 7, in response to receiving the report output command from the master ECRI, the CPU 5 of the satellite ECR 2 sets a start PLO code and an end PLU code based on the transmitted code. Next, start PL
Data to be read from the PLU file 31 is searched based on the U code. PL same as starting PLO code
If a U code is found, the data corresponding to that PLU code is read out and printed by the printer 8.

Subsequently, it is determined whether the end PLU code has been reached, and if the end PLU code has not been reached, the data of the next PLU code is read and printed in the same manner as described above. In this way, all data from the start PLU code to the end PLU code is read and printed. When printing of all data is finished, the CPU 5 sends a PLU report end command to the master ECRI. Master EC
In response to receiving the PLU report end command from each satellite ECR2, R1 prints the error details and ends the operation. Here, the error contents include, for example, if the first satellite ECR2 does not respond,
"01?" is displayed, for example, the second satellite E.
If CR2 is down, “02E” is displayed and 3
If ECR2 (the th satellite) is processing, “03!
” is displayed.

In addition, when reading product codes from barcodes, if the barcode is in-store marking for which the store can define its own code system, the code system should be determined for each store in advance, and the PLU report for each store should be prepared. If this is published, sales etc. for each sales floor can be easily managed.

[Effects of the Invention] As described above, according to the present invention, when a master device instructs each of a plurality of satellite devices to issue a report, each satellite device determines whether or not it can issue a report, and issues a report. The number of devices that can be issued is counted, and based on the counted value, the transaction file storage area is divided and allocated to each satellite device, information indicating the allocated area is notified to each satellite device, and each satellite When the device receives the notification, it reads the memory contents corresponding to the notification content from the transaction file and prints out the report all at once. This eliminates the need for a host computer, which reduces costs. Reports can be issued in a short period of time without requiring additional time, and operations after closing can be carried out efficiently.
