Description

The present invention relates to a data processing device such as an electronic cash register or POS (point of sale information management) terminal for registering product sales data.

[Prior Art] For example, in a POS terminal device that accumulates and manages daily product sales and weekly product sales by accumulating input product sales data in various cumulative memories, It has a built-in single item table in which single item data such as item name and unit price is set according to the single item code of the product, and a message table in which various message data is set. Settings or changes of these setting data are transmitted. This is done in real time by DLL (down line loading) processing from a host computer (store controller) connected inline via a line.

However, if you change the setting data while the store is open, it may affect the aggregated data in various cumulative memories and the sales management function may become insufficient.
Actually, DLL processing of these data is performed before opening or after closing. For this reason, the operator of the host computer, which operates DLLs of the setting data for POS terminals that are open late in the morning, such as convenience stores, which open late in the morning or when the store opens early in the morning. I had to work within the designated time, which was a heavy burden.

[Problems to be Solved by the Invention] As described above, in the conventional data processing device such as the POS terminal, when the setting data is sent by the DLL process of the host controller, the setting data is stored in the memory in real time. Since the data processing result may be reflected and the data processing result may be affected, there is a limit to the time for setting or changing the data.

Therefore, according to the present invention, the setting data that is transmitted and input from the outside is reflected in the memory in real time, so that the setting data that affects other data in the memory is reflected in the memory at a predetermined timing that does not have any subsequent influence. An object of the present invention is to provide a data processing device that can be configured to eliminate the time limit of data setting work.

[Means for Solving the Problems] The present invention provides a data processing device including a memory for storing setting data from the outside, executing a program based on input data, and performing data processing using the setting data in the memory. , A setting data storage buffer, means for fetching setting data from the outside, and setting data fetched by this means should be set in the memory in real time or set in the memory at any timing other than real time. Setting data determining means for determining whether or not the data should be set, and the data determined to be set in real time by this determining means is set in the memory at appropriate times, and the data determined to be set by arbitrary tamming is set. Once stored in the data storage buffer, read from the buffer at the appropriate timing and stored in the memory. And a data setting control means for setting.

Further, the clock circuit for clocking the current time and the current time clocked by the clock circuit when the data is read from the setting data storage buffer at any timing by the data setting control means and set in the memory are read. And a data output unit that outputs the setting management data that is stored and held by this holding unit. Good.

[Operation] In the case of a data processing device having such means, when setting data is sent from the outside, the setting data should be set in the memory in real time or should be set in the memory at any timing other than real time. It is determined whether the data. Then, the data determined to be set in real time is set in the memory at appropriate times. On the other hand, the data determined as the data to be set by the arbitrary tamming is temporarily stored in the setting data storage buffer. Then, at the corresponding timing, it is read from the same buffer and set in the memory. Therefore, since the timing for reflecting the setting data in the memory is automatically selected, it is not necessary for the sending side of the setting data to consider the timing for reflecting the setting data in the memory.

The provision of the clock circuit, the setting management data holding means and the data output means makes it possible to obtain management data such as when the setting data set in the memory is reflected in the memory at any timing other than real time.

In the RAM 23, as shown in FIG. 3, a setting data memory 41 for storing various setting data from the host computer 12 such as individual product data such as individual product code, product name and unit price of each product and message data, a daily data. A daily total memory 42 that cumulatively stores sales data such as sales points and sales amounts by item and department, and a week in which sales data such as sales points and sales amount for one week are categorized by item and department etc. Total memory 42, work memory used for data processing such as calculation
44, first to third data buffers 45, 46, 47 for temporarily storing the setting data by the DLL processing from the host computer 12 in text units, the setting including the information for identifying the setting data and the time data of the data setting time In addition to a setting management data buffer 48 for temporarily storing management data, a reception buffer 49, a transmission buffer 50, etc. are formed.

One text of the setting data sent from the host computer 12 by the DLL processing is, as shown in FIG. 4, a header 51 indicating the setting data, a classification code 52 indicating the type of the setting data, and the setting data 53. It is formed from and.

When the power is turned on, the CPU 21 executes the main routine according to the OS (operating system) program in the ROM 22. When key data is input from the keyboard 28 in the state where the "registration" mode is selected by the mode switch, the registration work processing corresponding to the key data is performed by the task processing. Further, the program is set to execute the subroutine shown in FIGS.

FIG. 5 is a subroutine that is executed when the data from the host computer 12 is stored in the receive buffer 49. When the received data is the setting data by the DLL processing, this received data is divided into the first by one text unit. The data is stored in the data buffer 45. When all the setting data have been stored in the first data buffer 45, the process returns to the main routine.

On the other hand, when the received data is the setting management data request command, the setting management data for one text is read from the setting management data buffer 48 and set in the transmission buffer 50. Then, all the data in the setting management data buffer 48 is advanced by one text. Next, the contents of the transmission buffer 50 are transmitted to the host computer 12 (data output means). The above processing is performed for all the data in the setting management data buffer 48, and when the data in the buffer 48 is exhausted, the process returns to the main routine.

FIG. 6 is a subroutine that is executed at regular time intervals by timer monitoring. When the flow chart starts, it is determined whether or not setting data is stored in the first data buffer 45. If not stored, the procedure returns to the main routine.

When the setting data is stored in the first data buffer 45, the setting data for one text is read and all the data in the first data buffer 45 is moved up by one text. Next, the classification code of the read setting data is recognized. Then, it is determined whether or not the setting data determined by this classification code is of a type that can be set in the setting data memory 41 in real time (setting data determining means).
That is, when the setting data is reflected in the memory 41 in real time, if it does not affect the accumulated data in the daily total memory 42 or the weekly total memory 43, it is determined that the data can be set in real time, and the setting data memory 41 This setting data is stored in the corresponding area of. However, when a higher-level task such as a registered business process is operating, it waits for the completion of the process before storing. (First data setting control means).

On the other hand, when the read setting data is reflected in the memory 41 in real time, if it affects only the accumulated data of the daily total memory 42, this setting data is stored in the memory 41 after the adjustment of the daily total memory 42. Since the setting is made, this setting data is transferred to the second data buffer 46 (setting data holding means).

If the cumulative total data of the weekly total memory 43 is affected, the setting data is set in the memory 41 after the adjustment of the total memory 43.
32 Transfer to the data buffer 47 (setting data holding means).

After that, the setting data for the next one text is read from the first data buffer 45 and the same process is repeated. When the data in the buffer 45 is exhausted, the process returns to the main routine.

FIG. 7 is a main routine executed when the daily checkout execution key is operated with the "settlement" mode selected by the mode switch 26. That is, when the flow chart starts, the data in the daily memory 42 is sequentially read and set in the transmission buffer 50, and the contents of the transmission buffer 50 are transmitted to the host computer 12. And the daily total memory 42
When the transmission of all the data in the above is completed, the daily total memory 42 is cleared and the daily total settlement processing is completed.

Next, it is determined whether or not the setting data is stored in the second data buffer 46, and if it is not stored, the process returns to the main routine. When the setting data is stored, the setting data for one text is read from the buffer 46 and all the data in the buffer 46 is moved up by one text. Then, the read setting data is stored in the corresponding area of the setting data memory 41 (second data setting control means). Also,
The current time measured by the clock circuit 24 is read, the setting management data consisting of this time data and the classification code of the data set in the memory 41 is edited and stored in the setting management data buffer 48 (setting management data Holding means).

Then, the setting data for the next one text is read from the second data buffer 46 and the same process is repeated. When the data in the buffer 46 is exhausted, the process returns to the main routine.

FIG. 8 is a main routine that is executed when the weekly total payment execution key is operated with the "settlement" mode selected by the mode switch 26. That is, when the flow chart starts, the data in the weekly memory 43 is sequentially read and set in the transmission buffer 50, and the contents of the transmission buffer 50 are transmitted to the host computer 12. And weekly memory 43
When the transmission of all the data in is completed, the weekly total memory 43 is cleared and the weekly total settlement processing is completed.

Next, it is determined whether or not the setting data is stored in the third data buffer 47, and if it is not stored, the process returns to the main routine. When the setting data is stored, the setting data for one text is read from the buffer 47 and all the data in the buffer 47 is moved up by one text. Then, the read setting data is stored in the corresponding area of the setting data memory 41 (second data setting control means). Also,
The current time measured by the clock circuit 24 is read, the setting management data consisting of this time data and the classification code of the data set in the memory 41 is edited and stored in the setting management data buffer 48 (setting management data Holding means).

Then, the setting data for the next one text is read from the third data buffer 47 and the same process is repeated. If the data in the buffer 47 is exhausted, the process returns to the main routine.

In the POS terminal 11 of the present embodiment configured as described above, when the setting data is transmitted from the host computer 12, the setting data is temporarily stored in the first data buffer 45.
To be stored. Then, the first data buffer 45 is checked at regular time intervals by timer monitoring, and if the setting data is stored, the data is sequentially read in units of one text. Then, it is determined from the read data classification code whether or not the setting data can be set in the setting data memory 41 in real time.

Here, if the accumulated data in the daily total memory 42 or the weekly total memory 43 is not affected when the data is reflected in the setting data memory 41, such as the name of single item data or message data, the data can be set in real time. A judgment is made and it is confirmed that a higher-level task such as registration work processing is not operating, and the setting data is stored in the corresponding area of the setting data memory 41.

On the other hand, by reflecting it in the setting data memory 41 such as the unit price of single item data, the daily total memory 42
In the case of data that affects only the accumulated data of, in order to set it in the setting data memory 41 after the daily total settlement process is completed,
This setting data is temporarily stored in the second data buffer 46. Further, in the case of data that affects the cumulative data of the weekly total memory 42 by reflecting it in the setting data memory 41, after the completion of the weekly total settlement processing, the setting data memory 41
This setting data should be set to the third data buffer 47
Temporarily store in.

However, when the day-to-day operation is completed and the daily total settlement process performed after the store is closed, the setting data stored in the second data buffer 46 is automatically read and stored in the corresponding area of the setting data memory 41. Is set. Then, at this time, the setting management data consisting of the classification code of the setting data and the setting time data is stored in the buffer 48.
The setting management data stored in 48 is stored in the host computer 12
Is collected in the host computer 12 in response to a request command from the.

When the weekly checkout process performed every week is completed, the setting data stored in the third data buffer 47 is automatically read and set in the corresponding area of the setting data memory 41. Also in this case, the setting management data including the classification code of the setting data and the setting time data is stored in the buffer 48, and the setting management data stored in the buffer 48 responds to a request command from the host computer 12 To be collected.

Thus, according to this embodiment, the host computer 12
Even if the setting data is sent from the POS terminal 11 to the POS terminal 11 by DLL processing, the setting data is set in the setting data memory 41 in real time as long as the setting data does not affect the cumulative memory. It is temporarily stored in 47. Then, the setting data is read out from the buffers 46 and 47 in consideration of the timing having no influence, and is automatically set in the setting data memory 41. Therefore, when transmitting the setting data from the host computer by the DLL processing, it is not necessary to consider the influence of the setting data on the memory, so that even when the store is opened, the data setting or changing operation can be performed. Therefore, the operator of the host computer 12 does not need to set or change the data before or after the store is opened and the burden is reduced.

In other words, in the past, the DLL processing of the setting data had to be performed before opening the store and after closing the store.
According to the present embodiment, since the same processing can be performed even during the opening of the store, it is possible to set and change the setting data that does not affect the accumulated data in real time even during the opening of the store, thus improving the practicality.

Further, for data set late in the memory 41, setting management data consisting of a classification code for identifying the type of the data and the data setting time is created and accumulated in the buffer 48, and the setting data from the host computer 12 is sent. Since the data is collected in the host computer 12 in a timely manner in response to the request command, the operator of the host computer 12 can confirm that the data setting is surely executed by looking at the collection result of the setting management data.

Although the POS terminal incorporated in the POS system has been illustrated in the above embodiment, a data processing device having a memory for storing setting data and setting data to the memory from the outside is general. Applicable to Further, even a data processing device having no communication means with a host controller can be applied as long as data setting is performed from an external memory such as a floppy disk. In this case, the output of the setting management data may be a display output if the device has a display device, and a printout if the device has a printer.

Further, if the data processing device has a floppy disk driver, it is possible to use a floppy disk as a memory for temporarily storing the setting data and the setting management data. In addition, it goes without saying that various modifications can be made without departing from the scope of the present invention.

[Effects of the Invention] As described in detail above, according to the present invention, setting data that is transmitted and input from the outside and reflected in the memory in real time affects other data on the memory. It is possible to provide a data processing device that can be reflected in the memory at a predetermined timing that does not have an influence thereafter and can eliminate the time limit of the data setting operation.

According to the second aspect, it is possible to provide a POS system capable of confirming that the data to be processed at an arbitrary timing other than the real time is surely set in the memory at that timing.
