The product sales data consisting of is acquired, and this product sales data is stored in the RAM3.
In addition to performing registration processing in the storage unit formed in the, the receipt print data including the product identification code, the product name, the sales amount, and the like journal print data are created, and the receipt print data is printed out on the receipt paper by the receipt printer 13. In addition, the journal print data is printed out on the journal paper by the journal printer 14, and the product registration operation is executed.

In addition, the "registration" mode is preset to the total amount of all tax-excluded products out of all registered products when the subtotal key is keyed in after executing the registration business for all the products sold as one sales transaction. The tax amount is calculated by multiplying the tax rate, the total amount of all registered products is added to this tax amount to calculate the total amount including tax, and the total amount including tax is displayed on the display unit 11 and the identification data indicating the subtotal amount is displayed. From the first line receipt print data consisting of "subtotal" and the total amount of all registered products and similar journal print data, identification data "external tax" indicating the amount of external tax and the total amount and tax amount of products subject to external tax The receipt print data of the second line and the same journal print data are created, and the receipt print data of the first line and the second line are sequentially printed out on the receipt paper by the receipt printer 13.

Create data and create receipt data for the 5th and 6th lines. In the business mode for executing the registration closing work in which the receipt printer 13 sequentially prints out the receipt paper, and the journal print data of the fifth and sixth lines is sequentially printed out on the journal paper by the journal printer 14. is there.

The "inspection" mode is a mode of the work for displaying or printing out the data registered and stored in the storage unit by the product registration work as an inspection report,
Similar to the “check” mode, the “accounting” mode is a mode of operation in which the contents of the storage section are printed out as an adjustment report and then the storage section is cleared. The “setting” mode is necessary for executing various operations. This is a business mode in which data is preset in the RAM 3.

When the CPU 1 issues a request to print one-line print data on a journal sheet due to the execution of the merchandise registration work, the subtotal work, or the registration closing work, the CPU 1 executes the journal printing process shown in the flowchart of FIG. The program is configured to control the journal printing of the one-line print data.

That is, the CPU 1 initializes the two-dimensional code print data buffer 31 and the file print data buffer 32 provided in the RAM 3 as ST (step) 1 and the print character number counter N in the initialization processing such as power-on. Is being initialized, and in this state, ST2
It waits for a request to print one line of print data on the journal paper. And when there is a print request,
In step ST3, one-line print data on the journal paper corresponding to the current job is created, and in step ST4, the one-line print data is output to the journal printer 14 to control the printing of one line on the journal paper.

Next, at ST5, the number of print characters forming the current one-line print data is added to the print character number counter N. The number of characters to be printed includes CR command and LF command. Thereafter, in ST6, it is determined whether or not the print character number counter N exceeds the upper limit NMAX (for example, 2000 characters) corresponding to the capacity of the two-dimensional code print data buffer 31. (Data amount determination means) If it does not exceed, proceed to ST11 to perform the above 2
When the one-line print data of this time is stored in the dimension code print data buffer 31, the process returns to ST2.

On the other hand, when the print character number counter N exceeds the upper limit value NMAX in ST6, the two-dimensional data obtained by collecting all the journal print data accumulated and stored in the two-dimensional code print data buffer 31 in ST7. Edit the code print data. (Two-dimensional code print data creating means) Then, in step ST8, the print data of the two-dimensional data code is output to the journal printer 14 to control the two-dimensional data code print on the journal paper. (Two-dimensional code journal print control means) Then, in ST9, the print line number counter N is reset to "0", and in ST10, the print line number counter 2
If the dimension code print data buffer 31 is cleared, the process proceeds to ST11. If the current one-line print data is stored in the two-dimensional code print data buffer 31, S
Return to T2.

Further, the CPU 1 is programmed so as to execute the file creation work shown in the flowchart of FIG. It should be noted that this file creation work is, for example, a work that can be selected by inputting a predetermined key in the "check" mode. That is, when starting the file creation work, the CPU 1 first clears the file print data buffer 32 in ST21. Next, ST2
When the two-dimensional data code reader 16 waits for the two-dimensional data code to be read as 2, and the two-dimensional data code in which the journal print data is collected is input through the two-dimensional data code reader interface 17,
At ST23, the two-dimensional data code is analyzed and converted into print data for a plurality of lines. (Conversion means) Then, the print data is sequentially written in the file print data buffer 32.

Next, in ST24, the free space A of the file print data buffer 32 is checked, and in ST25, whether the free space A is less than the upper limit value NMAX corresponding to the capacity of the two-dimensional code print data buffer 31 or not. To judge. Then, if there is a free space A equal to or more than the upper limit NMAX, the process proceeds to ST28, and if it is confirmed that there is no key input for instructing the end of work, the process returns to ST22 and waits for the reading of the next two-dimensional data code. .

On the other hand, when the free space A is less than the upper limit value NMAX in ST25, even if the two-dimensional data code in which the journal print data is collected is read, the print data converted from this two-dimensional data code is stored in the file. Since it may not be possible to write to the print data buffer 32 for printing,
As 26, the contents of the file print data buffer 32 are written as a print data history file in the floppy disk mounted in the FDD 18. (File creating means) Then, if the file print data buffer 32 is cleared, the process proceeds to ST28, and if it is confirmed that there is no key input for instructing the end of work, the process returns to ST22.
Wait for the next two-dimensional data code to be read.

When a key input for instructing the end of work is detected in ST28, the contents of the file print data buffer 32 are written as a print data history file in the floppy disk mounted in the FDD 18 in ST29 (file creation). Means), and ends this file creation work. The history files of the print data written in the floppy disk in ST26 and ST29 are made to have different file names so that the previously registered files are not erased by mistake.

As described above, in the POS terminal of this embodiment, the history of merchandise sales transactions processed by the POS terminal is sequentially recorded on the journal paper. The journal print data is sequentially stored in the two-dimensional code print data buffer 31 and stored. When the number N of characters of the stored print data becomes close to the preset upper limit NMAX,
A two-dimensional data code, which is a collection of all the journal print data accumulated and stored in the dimension code print data buffer 31, is printed on the journal paper.

FIG. 4 shows the journal paper 4 in this embodiment.
In one printing example of 0, C1 and C2 represent two-dimensional data codes. L1 is the product identification code "14400
1,151601 ", product name, sales amount, and journal print data, L2 is journal print data that includes identification data" subtotal "indicating the subtotal amount and the total amount of all registered products, and L3 is the tax-excluded amount. Is the journal print data consisting of the identification data "excluding tax" and the total amount and tax amount of the products subject to tax exemption, and L4 is the journal print data consisting of the identification data "total" indicating the total amount and the total amount including tax. , L5 is journal print data including identification data “deposit” indicating the deposit amount and the deposit amount, L6 is journal print data including identification data “change” indicating the change amount and the change amount, and L7 is Journal print data consisting of transaction number, number of purchase points and purchase time, L8 is journal print data consisting of date and machine number, and L9 Is a journal printing data consisting of a cashier code and the cashier name.

That is, the two-dimensional data code C2 is 2
Journal print data L6 next to the dimension data code C1
Journal change data L7 (No.1234 2 point purchase 17: 1 from 2 change data code C2)
It is a two-dimensional data code that collects all journal print data up to 1TM).

Therefore, for example, when the maintenance base side investigates the cause of the abnormality of the POS terminal that has malfunctioned, the maintenance staff member has a journal paper 40 on which the operation history and the operation history from the user side to the occurrence of the failure are printed. The two-dimensional data codes C1 and C printed on the journal paper 40 by using a means such as facsimile communication or mail.
2 is read by a two-dimensional data code reader and is input to a personal computer or the like to input two-dimensional data codes C1 and C2.
It is possible to investigate the cause of the abnormality by converting the print data into print data, processing the print data into data that reproduces the operation up to the occurrence of the abnormality using a personal computer, and outputting the data.

Therefore, as compared with the conventional method in which the printed contents of the journal paper are visually confirmed and the operation up to the occurrence of the abnormality is reproduced, all that is required is to read the two-dimensional data code printed on the journal paper. It is possible to improve the efficiency of the work required to confirm the print contents of the journal paper.

Further, the POS terminal of this embodiment includes a two-dimensional data code reader 16 for reading a two-dimensional data code,
The FDD 18 for reading / writing data from / to a floppy disk which is an external storage medium is provided. Then, in the file creation work, the two-dimensional data codes C1 and C2 printed on the journal paper 40 are read by the two-dimensional data code reader 16 to convert the two-dimensional data codes C1 and C2 into print data, and this printing is performed. A print data history file in which data is stored in the order of generation is created and registered in the floppy disk.

Therefore, for example, when the cause of abnormality of the malfunctioning POS terminal is investigated on the maintenance site side, the user side is printed on the journal paper 40 on which the operation history and operation history up to the occurrence of the failure are printed. After the two-dimensional data code is read by the two-dimensional data code reader 16 in the order of generation to create a print data history file and register it in the floppy disk, the floppy disk is sent to the maintenance base. On the other hand, on the maintenance site side, the maintenance staff inputs the print data history file registered on the floppy disk to the personal computer, processes the print data into data that reproduces the operation up to the occurrence of the error, and outputs it. The cause can be investigated. Therefore, it is possible to further improve the efficiency of the work required for investigating the cause of the abnormality on the maintenance site side.

In the above embodiment, the two-dimensional data code is used as the two-dimensional code which is a collection of all the journal print data accumulated and stored by the print data storage means.
For example, a two-dimensional barcode formed by arranging a large number of barcodes each having a reduced bar length in a plurality of stages may be used as the two-dimensional code of the present invention.

In the above embodiment, the number of print characters is counted as a criterion for judging whether or not the amount of journal print data accumulated and stored by the print data storage means has reached a predetermined amount. However, the present invention is not limited to this. Instead, for example, when the number of print lines is counted and a predetermined line is reached, print data for a two-dimensional code, which is a collection of all the journal print data accumulated and stored by the print data storage means, is created and the journal is printed. May be.

Although a floppy disk is shown as the external storage medium for writing the print data history file in the above embodiment, the invention is not limited to this, and a magnetic tape, a memory card, a hard disk, etc. may be used.
Besides, the present invention can be variously modified within a range not departing from the gist of the present invention, such as applying the present invention to a product sales registration data processing device having a single electronic cash register or a journal printer but not a receipt printer. Of course.

[0040]

As described in detail above, according to the present invention, a two-dimensional code in which a large amount of print data on a journal sheet is collected can be printed on the journal sheet.
It is possible to provide the product sales registration data processing device that can confirm the print contents of the journal paper only by reading the dimension code, and can improve the efficiency of the work required to confirm the print contents of the journal paper.

Further, it is possible to provide a merchandise sales registration data processing device capable of easily creating a history file of print data on journal paper.
