Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to output processing in a sales data processing device such as an electronic register.

[Prior art] In sales data processing devices such as electronic registers, printing,
Sales details data that has been output once for display etc. may be output again later.

In this case, the conventional methods are to save the output content in the form of image data, and to create this image data, for example, the commercial crystal Nα by PLU, the number of sales,
There was a method to format and save basic data (code data) such as unit price, multiplication, return, etc.

[Problems to be Solved by the Invention] However, since various data processing is usually performed in code format, the method of saving in the form of image data makes it difficult to correct and re-output the saved image data, for example. When specifying the data to be corrected by code,
There is a problem in that it is difficult to specify the image data corresponding to the specified code.

Furthermore, in the method of formatting and saving basic data, there is a problem in that it is difficult to select a process for creating image data.

The problem of this invention is to - output sales data as an image,
Alternatively, it is possible to easily re-output the corrected data as an image.

[Means to solve the problem] The means of this invention are as follows.

The first storage means a (see the functional block diagram in FIG. 1; the same applies hereinafter) stores data in code format (including function codes) related to the registration process when the registration process is performed.
Remember.

The second storage means includes output control information for image output regarding the data in the first storage means a, and link information indicating which record in the first storage means a this output control information corresponds to. to remember.

When a predetermined instruction is given, the output control means C reads a corresponding record in the first storage means a based on the link information in the second storage means, and outputs the contents of the record as output control information. Output an image based on.

[Effect] The operation of the means of this invention is as follows.

Now, sales data and function information for each transaction in code format are inputted by key operations, registration processing is performed based on these input data, and the processing results are displayed and printed in character patterns (images). Assume that it has been output.

At this time, the first storage means a stores data such as function codes and input data in code format related to the registration process, and unit prices obtained by price look-up.

The second storage means also stores output control information for outputting images related to the data in the first storage means a, such as output information used for display output using the character pattern and print output. A jump destination address for jumping to the control program and link information indicating which record in the first storage means a this output control information corresponds to, for example, record Nα of the corresponding record, are stored. .

For example, when a predetermined instruction such as re-outputting the receipt is given, the output control means C sequentially reads out the record data in the second storage means, and records N on the record.
reading a record corresponding to α from the first storage means a;
Then, the function code in the code format, input data, price lookup unit price, etc. on the record read from the first storage means a are stored at the jump destination address on the record read from the second storage means a. The image is output according to the indicated program (output control information).

In this way, the data to be re-outputted stored in the code format is re-outputted as an image based on the output control information stored in association with the data.

Therefore, it is easy to re-output the sales data that has been output as an image, or the corrected data therefor.

[Example] An example will be described below with reference to FIGS. 2 to 8.

Note that the drawer 10 is opened by operating the cash/deposit key 2e.

RAM4 has a PL that stores cumulative sales data for each product.
In addition to cumulative files such as U file F1, there is also a data file F2 that stores data to be re-output (code format data including function codes), and to re-output the data in this data file F2 in the same image. An output control file F3 that stores control information of , and a work area WE are formed. In addition, the output III fl
The II file F3 includes a receipt/journal output control file F3a that stores output control information for receipts/journals, a slip print output control file F3b that stores output control information for slip printing, and a slip print output control file F3b that stores output control information for display. There is a display output control file F3c.

3(a) and 3(b) are data files F2 for outputting the receipt print contents shown in FIG. 3(c), respectively.
, which shows an example of the contents of the output control file F3.

That is, Fig. 3 (C) shows the contents printed on the receipt as sales detail data, and for products for which only one item was sold, the product name of the product by PLU is displayed as shown in the first line. video tape'.

Correspondingly, the sales amount of the product ￥1,000 is printed.In addition, for products that have been sold in multiple units, the number of sales 2°° shown on the second line and the multiplication sign ``*' °
, and the unit price code "" @pa and the unit price ゛°500゛° are printed, and on the third line, the product name of the above-mentioned multiple units sold "°floppy disk paper" and the total sales amount by product (second line (result of multiplying the number of items by the unit price) "¥1,000" is printed.Furthermore, for returned products, the characters ``Return゛°'' shown on the 5th line and the characters ``Return゛°'' shown on the 6th line are printed. Number of returned items “3”, multiplication sign “＊’°, and unit price sign”
@”, the unit price “1,500”, and the product name of the returned item “Compact Disc” shown on the 7th line are printed, and 8
The total return amount for each product shown in the 6th line (the result of multiplying the number of items and the unit price in the 6th line) is "¥4,500" printed.

The contents of the data file F2 shown in FIG. 3(a) indicate basic data for outputting the contents of FIG. 3(C) above. The data items of each record of this data file F2 are PLUNα, function information, quantity, amount, and unit price.

The above function information is 1 as shown in FIG.
The 1st bit is multiplication "X", the 2nd bit is return "RF"
Each bit of the 8-bit code corresponds one-to-one to eight types of function information, and the bit content "1'' indicates that the corresponding function information is set. Therefore, for example 1
When expressing different types of function information in 8 bits, for example, when recording 8 types of function information for one PLU product, 8 x 8 = 64 bits are required. When the function information is made to correspond one-to-one, all eight types of function information can be recorded using only 8 bits.

The contents of the output control file F3 shown in FIG. 3(b) are as follows:
It shows output control data for outputting the contents of FIG. 3(C) above. The data items of each record of this output control file F3 are an output function and a link Nα.

The link Nα indicates which record of the data file F2 shown in FIG. 3(a) corresponds to the data to be output, and is specifically indicated by the record Nα of the above records. In addition, the output function indicates control information when outputting the data of the record indicated by the record Nα,
Specifically, it is indicated by a jump address to the part of the program that controls the output.

Note that in controlling the output of the contents in the data file F2 according to the contents in the output control file F3, the CPUI utilizes the near-end flag F, pointer P, link Nα register R1, and work area WE in RAMB.

Next, the operation of the embodiment will be explained with reference to FIGS. 5 to 8.

Under various modes, when a code corresponding to sales data or a function code is input, the CPU checks the operating procedure and input errors such as over-digits (fifth step).
Figure step S1), input data is saved in a predetermined area of RAM 3 for last-minute correction (step S2), and processing is performed according to the mode, function code, etc., and input data, processing results, etc. are displayed and printed. (Step S3).

Next, data is written to the data file F2 in preparation for re-outputting the contents output in step S3 above (
Step S4), the output control information is written to the output control file F3 (Step S5).

Next, it is determined whether or not the near-end flag F is turned on (step S6). If it is turned on, guidance is displayed to that effect (step S7), and the process ends. On the other hand, when the near-end flag F is turned off, the process ends as is.

Next, based on FIG. 6, step S4 in FIG.
The processing will be explained in detail.

That is, first, a free area is searched on the data file F2 (step 541), and input data including function information, the unit price of the referenced product, etc. are stored in the searched free area on the data file F2 in response to the input of PLUNα. Writing (step 542), at this time, the function information is written with the corresponding 8 bits set (1) and reset (0) as described above, and more than a predetermined value is written in the data file F2. It is determined whether or not there is an empty area (step 543), and if there is no empty area larger than a predetermined number, the near-end flag F is turned on (step 544), and the process ends. on the other hand,
If there are more than a predetermined number of empty areas, the process ends immediately.

Next, based on FIG. 7, step S5 in FIG.
The processing will be explained in detail.

That is, first, a free area is searched on the output control file B3 (step 551), and a jump address to the program that performed the output process in step S3 in FIG. and writes the record Nα of the corresponding record on the data file F2 as a link Nα (step 55
2), and it is determined whether there is a predetermined or more empty area in the output control file F3 (step 553),
If there are no vacant areas larger than the predetermined number, the near-end flag F is turned on (step 554), and the process ends. On the other hand, if there are more than a predetermined number of empty areas, the process ends.

Note that when writing data to the data file F2 and the output control file F3, a series of Nα is added to each registered bone data, and distinction is made in units of registration. Further, when the near-end flag F is turned on and guidance is displayed to that effect, the operator clears arbitrary areas of the data file F2 and output control file F3 to secure an empty area.

Next, the registration details output process will be explained with reference to FIGS. 3, 4, and 8.

When ○ is specified for a series of transactions and the re-output key 2d is operated, the CPU 1 selects the series N in the output control file F3.
Pointer P
(step 581 in FIG. 8), and reads the code indicated by the pointer P (step 58).
2) Next, it is determined whether or not the record corresponds to the specified transaction amount, that is, whether all records for the specified transaction amount have been read out (step 883).
As a result, if everything has been read out, the process ends immediately.

On the other hand, if the record corresponds to the specified transaction, the output function on that record is stored in the work area WE on the RAM 4, and the link Nα is set in the link Nα register R (step 584). The code of the data file F2 corresponding to Nα is read out and stored in the work area WE (step 585).

Then, the data on the record read from the data file F2 is output based on the above output function (step 586).

For example, if the data of the Le chord in Fig. 3 (a>) is
), the output function is “product name” and amount °゛ (actually the program address), so according to the program corresponding to them (at the above address jump), respectively, the data PLUNα “0” of the code number in FIG. 3(a)
The character pattern data corresponding to the PLU product name and product name corresponding to the amount "1000" and the character pattern data corresponding to the amount "1000" are stored in the display RAM 8a and the print RAM 9a and output (see the first line of FIG. 3(C)). ).

In addition, the data of the second record in Figure 3(a) is
), when outputting based on the output function of the second record,
The output function is “number of pieces” and “unit price”, so
According to the programs corresponding to them, respectively, as shown in Fig. 3 (
The character pattern data corresponding to the number "2" of the second record in a) and the character pattern data corresponding to the unit price "500"° are stored in the display RAM 8a and the print RAM 9a.
Store it in and output it. At this time, the function information in the second record in Figure 3(a) is "01", and this "01゛° is only for the first bit to which multiplication is assigned, as shown in Figure 4. is “1” (set state), so as shown in the second line of Figure 3 (C),
A multiplication symbol *pa is added to the number "2" and output.

In addition, the same figure (
There are two records of b), like this,
When there are multiple records in the output control file F3 that link to the same record in the data file F2, when reading the record in the output control file F3 that includes the second and subsequent identical links Nα, link Nα in step S84
The setting process and the link record reading and storing process in step S85 are omitted.

After the output processing as described above, the pointer P is updated by the amount of the code (step 587), and the process returns to step S82, thereby executing the registration details output processing as described above for the specified transaction amount.

In this way, the control information for outputting the data on the data file F2 is stored correspondingly on the output control file F3, and image output processing is performed based on this control information. Therefore, selection of output processing is easy, and image output can be performed easily. Further, the data file F2 can be shared by the receipt/journal output control file F3a, the slip print output control file F3b, and the display output control file F3c, so that memory capacity can be saved. Furthermore, memory capacity can be saved by associating function information with each bit on a one-to-one basis.

[Effects of the Invention] According to the present invention, data in a code format that has been output as an image is stored in association with control information for re-outputting the data in the code format as an image, and based on this control information, Since the image re-output processing is performed □, the corresponding control information for image output can be easily selected, and it is easy to re-output the sales data that has been output as an image or the corrected data for it. be able to.
