By the way, "registration" means a mode in which sales data of each product registered for sale is registered in a sales registration memory, and a receipt sheet and a journal sheet are printed and a receipt is issued. "Registration" is a mode of operation in which the sales total data of each product stored in the sales registration memory is printed out as a sales inspection report on receipt paper. "Settlement" is the sales total data in the sales registration memory as a sales settlement report. After printing out on receipt paper, the mode of business that clears the total sales data in the sales registration memory, "Setting" is the mode of business that presets the data necessary for executing various tasks in the sales registration memory, etc. “Maintenance” is a mode of various maintenance work performed by a service person.

The keyboard controller 7 is provided with various function keys such as a numeric key for registering a product for sale, a PLU (price look up) key, a subtotal key, a deposit / cash total key, and a clear key. The dedicated keyboard 14 for the POS terminal is connected. The display controller 8 is connected to a display 15 for displaying the sales amount, total amount, etc. of each of the registered products for sale.

In the printer controller 9, a receipt printer as a receipt printing means for printing data on receipt paper, and for printing data on journal paper,
A journal printer is connected as a journal printing unit that winds and saves printed journal paper inside the apparatus. Here, in the "registration" mode, the receipt paper is printed with sales data and the like of each product registered for sale, discharged from the receipt issuing port to the outside of the terminal, and issued as a receipt. Further, in the "inspection" mode or the "settlement" mode, the total sales data stored in the sales registration memory is printed, discharged from the receipt issuing port to the outside of the terminal, and issued as a sales inspection report or a sales settlement report.

Therefore, the print data of the journal paper indicates the operation history of the POS terminal.

In the POS terminal of this embodiment, basically, in the "registration" mode, when the PLU code of the sale item is input by the numeric key and the PLU key, the host interface uses this PLU code. When the price of the sold product is inquired to the host device connected to 5, and the price response is received, the sales amount is acquired from this price and the sales amount, and the sales data of the sales amount and the sales amount is stored in the sales registration memory. Perform the registration process. In addition, the registered product data including the sales data is edited into display data and displayed on the display unit 15, and the registered product data is edited into print data and output to the receipt printer 16 and the journal printer 17 to print receipts. Make the journal print.

Further, various errors such as system error, memory parity error, communication error, etc., various input / output devices such as the receipt printer 16 malfunction, cancel processing, discount processing, registration minus processing, etc. In response to the execution of special processing such as maintenance processing and version upgrade processing, the corresponding journal print data is edited and output to the journal printer 17 for journal printing.

By the way, the POS terminal according to the present embodiment, as shown in FIG. 2, shows the journal print data relating to the state of the apparatus, such as the above-mentioned error information, failure information of various input / output devices, execution information of special processing, etc. R is the print message file 20 in which the importance is set for each print code and print message data corresponding to the print data.
It is stored in OM2 or RAM3. Here, the importance is the degree of usefulness from the viewpoint of the reliability of the device, maintenance, etc., and is expressed in five levels from importance “0” to importance “4” in the present embodiment, The higher the value, the higher the importance.

For example, since a system error and a memory parity error are serious errors that make the basic operation of the POS terminal impossible, the severity is set to "4". A communication error or a printer error seriously interferes with a part of the basic operation, so the importance is set to "3". Similarly, since the system installation information and version upgrade information are important information as the operation history of the device, the degree of importance is set to "3". on the other hand,
The degree of importance is set to "2" because the replacement information of a device such as a printer is history information required when the corresponding device fails. Further, the information regarding the special processing such as the cancellation processing, the discount processing, and the registration minus processing is the history information which is mild from the viewpoint of maintenance and the like, and therefore the importance is set to "1". Since the other journal print data is unnecessary from the viewpoint of maintenance and the like, the importance is set to “0”.

Further, the POS terminal of this embodiment is
As shown in FIG. 3, a reference importance degree memory 30 for setting and storing the reference importance degree X is formed in the RAM 3, and means for changing the reference importance degree X of the reference importance degree memory 30 is provided. This means is composed of the CPU 1 which executes the reference importance degree setting process shown in the flowchart of FIG.

That is, the CPU 1 uses the mode switch 1
When the input of the code instructing the execution of the reference importance degree setting process is detected from the keyboard 14 in the state where the “setting” mode is selected by 2, the reference importance degree setting process is selected in ST (step) 1 of FIG. Confirmed that
As ST2 and ST3, the system waits for the reference importance level X within the predetermined range (0 to 4) to be input by the numeral keys. When the input of the reference importance level X is detected, ST4
Then, the reference importance X is written in the reference importance memory. Further, at ST5, a print code requesting journal print data of reference importance setting processing information is generated. After that, if the start of the journal print processing is instructed in ST6, the reference importance setting processing ends.

Further, the POS terminal of this embodiment is
As shown in FIG. 4, an important data holding file 40 that stores and stores the journal print data together with the date and time of occurrence in the order of occurrence is formed in the EEPROM 10.
When the journal print data relating to the state of the apparatus is generated, its importance is determined, and when the journal print data is a specific reference importance or higher, the journal print data is written and held in the important data holding file 40. There is. This means is composed of the CPU 1 that executes the journal printing process shown in the flowchart of FIG.

That is, the CPU 1 detects in ST11 that a start command for journal print processing has been generated by executing processing in various business modes such as "registration", "inspection", "payment", "setting", and "maintenance". Then, in ST12, it is determined whether or not there is a print code requesting journal print data. If there is a print code, it is a print request for journal print data relating to the state of the apparatus. Therefore, the print message file 20 is searched with this print code in ST13, and print message data corresponding to the print code and important Read degrees and. Next, ST
When the journal print data is created based on the print message data as 14, the journal print data is output to the journal printer 17 via the printer controller 9 and printed on the journal paper as ST15.

Thereafter, at ST16, the importance of the journal print data is compared with the reference importance X stored in the reference importance memory 30. Then, when the importance of the journal print data is smaller than the reference importance X, the journal print data is not the data to be stored and is of low importance, so the journal print processing is ended.

On the other hand, when the degree of importance of the journal print data is equal to or higher than the reference degree of importance X in ST16, the journal print data is the data to be stored which is highly important, and therefore is read from the clock circuit 4 in ST17. The date and time data is the date and time of occurrence. After that, if the journal print data is written and held in the important data holding file 40 in the order of occurrence together with the date and time of occurrence data in ST18, the journal print processing is ended. If there is no print code in ST12, it is a journal print command for sales data of registered products, so if the journal print data is output to the journal printer 17 via the printer controller 9 and printed on the journal paper. If this is the case, the journal printing process ends.

Further, the POS terminal of this embodiment is
There is provided means for causing the receipt printer 16 to print the journal print data stored and held in the important data holding file 40 of the EEPROM 10 on the receipt paper in response to the print command from the command means. This means is a CPU that executes the important data output process shown in the flowchart of FIG.
It is composed of 1.

That is, the CPU 1 uses the mode switch 1
When the input of the code for instructing the execution of the important data output process is detected from the keyboard 14 in the state where the "maintenance" mode is selected by 2 (instructing means), ST21 of FIG.
In step ST22, it is confirmed that the important data output process has been selected, and in step ST22, the data for designating the output period (start date to end date) is waited for by key input by the numeric key. Then, the input number of the output period (for example, 1
If "199950101.199950930" is detected from January 1, 995 to September 30, 1995), all the journal data stored and stored in the important data storage file 40 is read as ST23, and ST
Reference is made to the occurrence date / time data corresponding to each journal print data as 24, and all the journal print data within the output period is extracted.

After that, if all the journal print data in the output period extracted in ST25 are re-edited into the receipt print data, this receipt print data is output to the receipt printer 16 via the printer controller 9 in ST26. , Print on receipt paper.

After that, if the input of the deposit / cash total key for instructing the end of the work is detected in ST27, this process is ended. If it is confirmed in ST22 that the next output period is designated before the end of work is instructed in ST27, the processes in ST23 to ST26 are repeated. When the period designation is "0" in ST22, all the journal print data in the important data holding file 40 is read and printed out on the receipt paper.

As described above, in the POS terminal of the present embodiment, the importance of various journal print data relating to the state of the apparatus among all the data printed on the journal paper is preset by the print message file 20, When the journal print data relating to the state of the apparatus is generated, its importance is judged, and when the journal print data is a specific reference importance or higher, the journal print data is a non-volatile storage medium EEPRO.
The important data holding file 40 of M10 is written and held.

Therefore, among various kinds of journal print data relating to the state of the apparatus, the journal print data which is more important than the reference importance can be stably stored and held for a long period of time. As a result, it is possible to easily grasp the important error occurrence history and the failure occurrence history by only checking the data stored in the important data holding file 40 when performing the maintenance of the device. The load required for work such as investigating the cause of a failure or abnormal operation can be greatly reduced as compared with the conventional method in which necessary history information is acquired by analyzing print contents of a large amount of journal paper. Note that the ratio of journal print data that is more important than the standard importance is very small compared to all print data,
There is no problem in capacity even if it is stored for a long period of time.

In the POS terminal of this embodiment, the journal print data stored and held in the important data holding file 40 for a long time can be printed out on the receipt paper by the receipt printer 16 in the "maintenance" work. It is like this. Therefore, the important journal print data stored in the important data holding file 40 can be confirmed quickly with a simple operation.

Further, in the POS terminal of this embodiment, the date and time of occurrence data is added when the important journal print data is written in the important data holding file 40. Then, when the important journal print data stored in the important data holding file 40 is printed out on the receipt paper, the output period is designated so that only the important journal print data generated within the designated period is extracted. It prints on receipt paper. Therefore, since the important journal print data within the necessary period can be confirmed by a simple operation, the burden required for work such as investigating the cause of a failure or abnormal operation can be further reduced.

Further, in the POS terminal of the present embodiment, the RAM 13 is provided with the reference importance memory 30, and the journal print data having the reference importance X or higher set in the memory 30 is extracted to store the important data holding file. 40 is written and held. Then, the reference importance level X in the reference importance level memory 30 can be changed to a desired reference importance level X by executing the reference importance level setting process in the "setting" work. Therefore,
The journal print data positioned as important to the user can be selected and saved, and the practicality can be improved.

Although the EEPROM 10 is used as the non-volatile storage medium in the POS terminal of this embodiment, it may be a hard disk or the like. Further, as shown in FIG. 8, a memory card interface 19 capable of writing data to the memory card 18 such as an IC card is connected to the CPU 1 via a bus, and the important data holding file 40 is stored on the memory of the memory card 18. May be formed, and the journal print data in which the importance of the reference importance X or higher is set may be written in the important data holding file 40 on the memory card 18. A floppy disk drive device may be provided and a floppy disk may be used instead of the memory card.

Since the memory card and the floppy disk are portable storage media, they should be detached from the POS terminal when necessary, and the data in the important data holding file 40 should be separately read and analyzed using a data processing device such as a personal computer. This makes it possible to perform work such as investigating the cause of failure or abnormal operation more simply and with high reliability.

In the POS terminal of this embodiment, the case where the data in the important data holding file 40 is printed out is shown, but it may be displayed on the display 15 in the "maintenance" work, for example. Further, the important data holding file 40 on the non-volatile storage medium is stored together with the journal print data together with the degree of importance,
The journal print data of a desired importance may be output by designating the importance at the time of output. In addition, it is needless to say that various modifications such as the rank of the importance of each journal print data can be implemented without departing from the scope of the present invention.

[0042]

As described above in detail, according to the first aspect of the present invention, it is possible to easily confirm the print data of high importance among all the print data printed on the journal paper even after a long period of time. Therefore, it is possible to provide a product sales registration data processing device that can significantly reduce the burden required for work such as investigating the cause of failure or abnormal operation.

According to the second aspect of the present invention, in addition to the above effects, the merchandise sales registration data processing device which can arbitrarily specify the importance of the print data extracted as the important data and can improve the practicality Can be provided.

According to the third aspect of the present invention, it is possible to provide a merchandise sales registration data processing device capable of analyzing highly important print data by using a device such as a personal computer.

Further, according to the invention of claim 4 of the present application,
