M4b (second additional information) is displayed in association with the property name. In the example of FIG. 13, a cross is circled in association with the property names of "consumer_id", "discounts", "memberships", "payment_methods", "products", "sale_type", and "subtotal". The mark M4b is displayed. The item for which the acquisition of the item value has not been completed is an item in which the null value is described in association with the item in the generated analysis data when the analysis data is generated by the corresponding parser PS function. As described above, when the analysis data is generated, the null value is described in association with the item for the item for which the data type conversion has failed. Such items also correspond to "items for which item values could not be obtained".
The user selects one item among the items displayed on the item selection screen G41 by hovering the cursor over one item and performing a predetermined operation (for example, double-clicking on the mouse). be able to. For items selected by the user, the property name is enclosed in a rectangular frame to clearly indicate that the user has selected. The user can move the cursor on the fourth user interface UI4 and other user interfaces by using a mouse, keyboard, and other input devices.

By referring to the item selection screen G41, the user can easily and intuitively recognize the required items, and can easily and intuitively recognize the items for which the item values could not be acquired.

When displaying the item selection screen G41, the control server control unit 40 refers to the analysis data management database 422 and acquires the print text data received from the printing device 12 of the serial number J11 selected by the user in the second user interface UI2. .. At that time, the control server control unit 40 acquires the print text data to be displayed on the third user interface UI 3 when the display button B2a of the second user interface UI 2 is operated.
Hereinafter, the printing device 12 having the serial number J11 selected by the user in the second user interface UI 2 is referred to as a "selective printing device". Further, the acquired print text data is referred to as "text data to be processed".

Next, the control server control unit 40 refers to the parser management database 421 and acquires the parser set PSS of the selective printing apparatus. Next, the control server control unit 40 analyzes the text data to be processed by the function of the acquired parser set PSS, and determines that the item value can be acquired or the item value cannot be acquired for each of the receipt items. Note that the item value of one item can be acquired means that in the analysis data generated based on the analysis of the text data to be processed, the item value of a value other than the null value is described in association with the item of 1. Means that. Further, the fact that the item value of one item cannot be acquired means that the null value is described in association with the item 1 in the analysis data generated based on the analysis of the text data to be processed.
Next, the control server control unit 40 displays the item selection screen G41 in which the mark M4b is displayed at an appropriate position in the first area A41 based on the determination result.

<Third area A43>
Next, the third region A43 will be described.
The text display screen G43 is displayed in the third area A43 of the fourth user interface UI4. The text display screen G43 is a screen on which the text described in the text data to be processed is displayed.
As described above, the text data to be processed (printed text data) is text data in which the information printed as characters on the receipt is described in a state in which the order in printing and the line feed in printing are reflected. Therefore, information is arranged in the text displayed on the text display screen G43 according to the layout of the receipt. By referring to the text display screen G43, the user can easily and intuitively grasp the content of the information described in the text data to be processed and the layout of the corresponding receipt.

Further, on the text display screen G43, the text based on the text data to be processed is displayed in a state in which "word" (described later) can be selected as a keyword (described later).
Hereinafter, "words" will be described in detail. In the following description, the character code representing a line feed is expressed as a "line feed character".

Here, in the present embodiment, there are "separator characters", "special characters", and "ordinary characters" as character types.
The delimiter character is a white space character and a line feed character. The delimiter is used to determine the delimiter between words, as will be described later.
The special character is a predetermined symbol among the symbols. Special characters are symbols that may be used for information with special meanings such as area division information. In the present embodiment, the special character includes the character "-", the character "~", the character "=", and the character ":".
Ordinary characters are characters excluding delimiters and special characters.

A word is (1) a character string consisting of consecutive ordinary characters without being separated by a delimiter character (may be one character. Hereinafter, one character is also appropriately expressed as a "character string"), or. (2) A character string consisting of consecutive special characters without being separated by a delimiter character.
FIG. 14A is a table showing the words included in the print text data T1 of FIG. 6A with “lines” clearly indicated.
FIG. 14B is a table showing the words included in the print text data T2 of FIG. 6B with “lines” clearly indicated.
For example, in the case of the printed text data T2 of FIG. 6B, the character string "CheckNO." Corresponding to the receipt identification explicit information J41 and the character string "C0001" corresponding to the receipt identification information J42 are separated by delimiters, respectively. It is a character string consisting of continuous ordinary characters. Therefore, these character strings correspond to "words".
Further, for example, in the case of the print text data T2 of FIG. 6B, the character string “sub”, the character string “−”, and the character string “total” constituting the subtotal explicit information J71 correspond to words, respectively. That is, the character string "sub" is a character string composed of continuous ordinary characters without being separated by a delimiter character. Further, the character string "-" is a character string composed of consecutive special characters without being separated by a delimiter character. Further, the character string "total" is a character string composed of continuous ordinary characters without being separated by a delimiter character. Therefore, the subtotal explicit information J71 is information in which three words are continuously composed.
Further, the area division information is a character string composed of consecutive special characters without being separated by a delimiter character. Therefore, the area division information corresponds to a "word".

When displaying the text display screen G43, the control server control unit 40 decomposes the information included in the text data to be processed into words. Next, the control server control unit 40 sets the text described in the text data to be processed in a state in which each of the decomposed words and each of the blank characters can be independently selected when selecting a keyword (described later). , Displayed on the text display screen G43. The details will be described below.
Here, as will become clear later, in this embodiment, a blank character can be selected as a part of the keyword. Based on this, in the following, whitespace characters are assumed to be included in the word.

15A and 15B are diagrams showing an example of the text display screen G43 together with the cursor CS that can be moved by the user.
When the cursor CS overlaps the area of a word or a blank character on the text display screen G43, the control server control unit 40 sets the background color of the background of the area of the word or the blank character to a predetermined color (yellow in the present embodiment). ) (Apply the prescribed decoration).
FIG. 15A shows how the cursor CS overlaps the area of the word “SUB”. As shown in FIG. 15A, when the cursor CS overlaps the area of the word "SUB", the background color of the area changes to yellow.
FIG. 15B shows how the cursor CS overlaps the whitespace area between the word “SUB” and the word “TOTAL”. As shown in FIG. 15B, when the cursor CS overlaps the blank character area, the background color of the area changes to yellow.
The decoration applied to the word on which the cursor CS overlaps (the word that is a candidate for selection) is not limited to the decoration that changes the background color. The character string corresponding to the word may be bolded, emphasized, or underlined.

Here, the word on which the cursor overlaps or the blank character is a word or a word in a state where it is a candidate to be selected as a keyword when selecting a keyword (or a part of the keyword as described later) described later. It is a white space character. The user can hover over the desired word or whitespace character and confirm that the background color of the desired word or whitespace character is yellow so that the word or whitespace character can be selected as a keyword. By performing a predetermined operation (for example, double-clicking on the mouse) to instruct selection after confirming that, a desired word or a blank character can be surely selected as a keyword.

<Second area A42>
Next, the second region A42 will be described.
In the following description, the receipt item selected by the user on the item selection screen G41 of the first area A41 is referred to as a "selected receipt item".
In the second area A42 of the fourth user interface UI4, a screen for inputting information for generating a parser PS corresponding to the selected receipt item or selecting the information is displayed.
The user can generate a parser PS corresponding to the selected receipt item by selecting or inputting information on the screen displayed in the second area A42.
Hereinafter, the 15th parser PS15 (the selected receipt item is the total amount information item), the 5th parser PS5 (the selected receipt item is the cancellation presence / absence information item), and the 9th parser PS9 (the selected receipt item is the product information item). ) As an example, the screen displayed in the second area A42 and the processing of the control server 15 will be described.

<15th Parser PS15>
When generating the 15th parser PS15, the user selects the total amount information item (property "total") on the item selection screen G41.
FIG. 16 is a diagram showing a fourth user interface UI 4 when a total amount information item is selected on the item selection screen G41.
As shown in FIG. 16, when the total amount information item is selected on the item selection screen G41, the acquisition item value display screen G421 is displayed in the second area A42. The acquisition item value display screen G421 shows the analysis result (total amount information in the analysis data) when the text data to be processed is analyzed by the 15th parser PS15 associated with the serial number J11 of the selective printing device in the parser management database 421. The value described in association with the item.) Is displayed. In the example of FIG. 16, the null value is displayed on the item selection screen G41, which clearly indicates that the 15th parser PS15 cannot acquire the total amount information J92 at this time.
When displaying the acquired item value display screen G421, the control server control unit 40 refers to the parser management database 421, corresponds to the selective printing device, and acquires the parser PS corresponding to the selected receipt item. The control server control unit 40 analyzes the text data to be processed by the acquired parser PS, and displays the acquired item value display screen G421 based on the analysis result.

In the present embodiment, regardless of the selected receipt item, the control server control unit 40 displays the acquired item value display screen G421 in the second area A42, and selects and prints the parser PS registered in the parser management database 421. The analysis result of the parser PS corresponding to the device and the selected receipt item is displayed. This has the following effects.
That is, the user can easily and intuitively recognize the analysis result of the parser PS corresponding to the selected receipt item by referring to the acquisition item value display screen G421.
Further, the text display screen G43 of the third area A43 and the acquisition item value display screen G421 of the second area A42 are simultaneously displayed on the same user interface. Therefore, the user can refer to the text display screen G43 and the acquired item value display screen G421 while comparing them. Therefore, the user can determine the validity of the analysis result of the parser PS corresponding to the selected receipt item by comparing the text display screen G43 and the acquisition item value display screen G421. For example, regarding the total amount information item (property "total"), the user compares the value displayed on the acquisition item value display screen G421 with the value of the total amount information J92 displayed on the text display screen G43, and responds. It is possible to determine whether or not the parser PS can acquire the correct total amount information J92. Further, as described above, the sales method information J24 may or may not be printed on the receipt depending on the format of the receipt. Then, in the case of the format in which the sales method information J24 is not printed, the null value is correct in the analysis result of the corresponding parser PS. In this way, even if the analysis result of the corresponding parser PS is a null value, it may be correct that it is a null value. In such a case, the user can use the text display screen G43 and the acquired item value. By comparing with the display screen G421, it is possible to determine the validity that the analysis result is a null value.

As shown in FIG. 16, the acquisition item value display screen G421 of the second area A42 corresponds to the selective printing device and starts parser generation instructing the start of processing for generating the parser PS corresponding to the selected receipt item. Button QB is displayed.
When it is detected that the parser generation start button QB has been operated, the control server control unit 40 maintains the state in which the acquisition item value display screen G421 is displayed in the second area A42 and displays the frame selection screen G422. To do.

FIG. 17 is a diagram showing a fourth user interface UI 4 in which the frame selection screen G422 is displayed in the second area A42.
The frame selection screen G422 is a screen for selecting the type of rule for specifying the position in the print text data for the item value corresponding to the selected receipt item.
As described above, information is printed on the receipt according to the layout of the receipt. Therefore, in the print text data, the information corresponding to the item value of one item is described according to the rule corresponding to the one item reflecting the layout of the receipt. Therefore, the position of the item value of one item in the printed text data can be specified based on the rule corresponding to the one item.
Hereinafter, the rule used when specifying the position of the item value in the printed text data is referred to as a "search rule".
Then, there are a plurality of types of search rules depending on the method of specifying the position of the item value. For example, if the item value of one item is located to the right of the same line as the predetermined keyword, the search rule is a type of rule that specifies that the item value is located to the right of the predetermined keyword. is there. On the other hand, if the item value of one item is located to the left of the same line as the predetermined keyword, the search rule is a type of rule that specifies that the item value is located to the left of the predetermined keyword. is there.
In this embodiment, the types of search rules are managed using the concept of "frame". Therefore, on the frame selection screen G422, one or a plurality of frames are selectably displayed according to the type of one or a plurality of search rules corresponding to the selection receipt item.

Here, the layout related to the receipt has a characteristic that the total amount explicit information J91 is printed together with the total amount information J92, and the total amount explicit information J91 and the total amount information J92 have a predetermined positional relationship. Based on this, for the total amount information item (property "total"), the first total amount information frame and the second total amount information frame can be selected as frames.
In the first total amount information frame, the total amount information J92 is located on the same line as the total amount explicit information J91 as a keyword, one to the right of the total amount explicit information J91, or is located at the end of the same line. It is a frame corresponding to the search rule that specifies to do.
"The item value of 1 is located one line to the right of the keyword on the same line as the keyword" means that the item value of 1 is to the right of the keyword via one or more whitespace characters. Means to be located in. In addition, "the item value of 1 is located at the end of the same line as the keyword" means that the item value of 1 is located at the right end of the same line, and the character next to the item value of 1 is a line break. It means that it is a character.

The second total amount information frame is a search rule other than the search rule related to the first total amount information frame described above, and the total amount information is based on the positional relationship between the total amount explicit information J91 as a keyword and the total amount information J92. This is a frame corresponding to a search rule that specifies the position of J92.

On the frame selection screen G422 of FIG. 17, frame information JH17a explaining the first total amount information frame and frame information JH17b explaining the second total amount information frame are displayed in a list. Radio buttons are displayed in association with each of the frame information JH17a and the information related to the frame information JH17b. The user can select either the first total amount information frame or the second total amount information frame by using the radio button. By referring to the text display screen G43 displayed at the same time as the frame selection screen G422, the user can recognize the first total amount information frame and the second total amount information frame, which are appropriate frames to be applied. Based on this recognition, an appropriate frame can be selected.
As shown in FIG. 17, on the frame selection screen G422, a frame confirmation button XB for confirming the frame selection is displayed. When the control server control unit 40 detects that the frame confirmation button XB has been operated, the control server control unit 40 transitions the frame selection screen G422 to the step correspondence screen G423.

In the following description, the frame selected by the user is referred to as "selected frame".

One or more steps are prepared in advance for each frame. A step is a procedure for designating a search rule by selecting information about the search rule corresponding to the frame or by inputting the information. Then, one or a plurality of step correspondence screens G423 are prepared corresponding to one or a plurality of steps corresponding to the frame. The position of the item value in the printed text data may be identifiable based on a plurality of search rules. In such a case, a plurality of step-compatible screens G423 are prepared for one frame.
As will become clear later, the user needs to search for the item value corresponding to the selected receipt item by performing the work of selecting the frame and inputting the information on the one or more step correspondence screen G423. Alternatively, multiple search rules can be specified.
Hereinafter, the case where the selection frame is the first total amount information frame and the selection frame is the second total amount information frame will be sequentially described.

<1st total amount information frame>
FIG. 18 is a diagram showing a step correspondence screen G423 displayed in the second area A42 instead of the frame selection screen G422 when the first total amount information frame is selected on the frame selection screen G422 of FIG.

The following two pieces of information are displayed on the step correspondence screen G423 of FIG. (1) Rule information indicating a search rule that specifies that the total amount information J92 (item value) is located one to the right of the keyword in the same line as the keyword that first appears (uppermost) in the printed text data. JH18a. (2) Rule information JH18b indicating a search rule that specifies that the total amount information J92 (item value) is located at the end of the same line as the keyword that first appears (uppermost) in the printed text data. Further, a radio button is displayed in association with the two rule information, and one of the rule information can be selected by the radio button. The user specifies a search rule by selecting one of the rule information.
The user recognizes the positional relationship between the total amount information J92 and the keyword (total amount explicit information J91) by referring to the text display screen G43 displayed at the same time as the step correspondence screen G423, and corresponds to the rule information JH18a. Select appropriate information from the search rule and the search rule corresponding to the rule information JH18b.

In the rule information JH18a and the rule information JH18b, the keyword is expressed by the character string "'Text1'". Then, below the region A18b, a region A18a in which the word selected as a keyword is displayed is formed. As will become clear later, a keyword may be composed of a combination of multiple words (including whitespace characters). The character string "'Text1'" is displayed in the area A18a, and it is clearly shown that the word selected as the keyword is displayed in the area.

The user can select one or more words as keywords by the following method using the text display screen G43 of the third area A43.
Hereinafter, in the state where the fourth user interface UI4 shown in FIG. 18 is displayed, the user operates by taking as an example a case where the user selects a combination of the word "TOTAL" and the word ":" as a keyword. , And the processing of the control server control unit 40 will be described. The keyword "TOTAL:" corresponds to the total amount explicit information J91.
In the following description, a combination of a plurality of words is appropriately referred to as a "word group".

On the text display screen G43, the user puts the cursor on a word to be included in the keyword (including a blank character as described above). As mentioned above, the background color of the word on which the cursor is placed becomes yellow, clearly indicating that it is a candidate for selection.
FIG. 19 shows how the word “TOTAL” is a candidate for selection.

The user performs a predetermined operation (for example, double-clicking) while hovering the cursor over the word to confirm the word selection. When the control server control unit 40 detects that a predetermined operation is performed by the user and the word selection is confirmed, the selected word is displayed in the area A18a. The user can confirm the selected word by referring to the area A18a.
FIG. 20 shows a state in which the selection of the word “TOTAL” is confirmed and the word “TOTAL” is displayed in the area A18a.

After the selection of the word "TOTAL" is confirmed, the control server control unit 40 further executes the following processing. That is, the control server control unit 40 selects only the word adjacent to the word and located to the right of the word on the same line as the word whose selection has been confirmed most recently (in this example, the word "TOTAL"). Make it possible and underline the selectable words. In the example of FIG. 18, the control server control unit 40 makes only the word “:” adjacent to the word “TOTAL” selectable, and underlines the word “:”.
FIG. 21 shows a state in which the word “:” is selectable and the word “:” is underlined.
The user can easily and intuitively recognize the selectable word by referring to the underlined word.
The user recognizes that the word ":" can be selected, and then selects the word ":" in the same procedure as the word "TOTAL".
FIG. 22 shows a state in which the word “:” is selected following the word “TOTAL”, and the word “TOTAL” and the word “:” are continuously displayed in the area A18c as keywords.

In this way, the control server control unit 40 displays the text described in the print text data on the text display screen G43 in a state in which words (including blank characters) can be selected. Then, the control server control unit 40 sets a word or a word group selected by the user as a keyword. As a result, it is possible to surely prevent typos that may occur when the user sets a keyword by inputting characters with the keyboard, and to allow the user to select an accurate word or word group as the keyword.

Further, when selecting a keyword, the control server control unit 40 can select only a word adjacent to the one word and located to the right of the one word after the selection of one word is confirmed. To do. This has the following effects. That is, the receipt has a characteristic that the word group that can be used as a keyword consists of a combination of one or a plurality of consecutive words in one line. Based on this, when the control server control unit 40 executes the above-described processing, when the user selects a word group as a keyword, it is possible to sequentially select consecutive words in one line. In particular, the tax explicit information J81 of the printed text data T2 of FIG. 6B is a character string "sales Δtax", and is composed of a combination of the word "sales", a blank character, and the word "tax". When selecting the tax explicit information J81 as a keyword, it is necessary to include a white space character in the keyword, but it is assumed that the user may not recognize that the white space character needs to be included in the keyword. To. In this way, even when a word group including a blank character is selected as a keyword, the control server control unit 40 performs the above-described processing to ensure that the user selects the blank character as a part of the keyword. Can be made to.

The step correspondence screen G423 shown in FIGS. 18 to 22 has a step confirmation button SB and a confirm button CB.
The step confirmation button SB is a button to be operated when confirming the input to the step correspondence screen G423 on which the step confirmation button SB is displayed.

The confirm button CB is displayed on the last step correspondence screen G423 of the one or more step correspondence screens G423 corresponding to the selected frame. The confirm button CB can be selected in the following cases on the final step correspondence screen G423. That is, when the necessary information about the last step correspondence screen G423 is selected and input, the confirm button CB can be selected. When the confirm button CB is operated on the final step correspondence screen G423, the specification of the search rule is completed in all the steps corresponding to the selected frame.
The confirm button CB executes a process of acquiring an item value from the print text data based on the search rule specified on the screen G423 (all steps corresponding to the selected frame) corresponding to all steps corresponding to the selected frame. It is a button instructing the generation of the parser PS.

When the control server control unit 40 detects that the confirm button CB has been operated, the control server control unit 40 executes the following processing.
The flowchart FD of FIG. 23 is a flowchart showing the operation of the control server 15 when it is detected that the confirm button CB has been operated.
As shown in the flowchart FD of FIG. 23, the control server control unit 40 acquires the search rule specified on all the step correspondence screens G423 corresponding to the selected frame (step SD1).
Next, the control server control unit 40 generates a parser PS that executes a process of acquiring the item value of the selected receipt item based on each of the acquired search rules (step SD2). Here, the control server 15 is provided with a parser PS equipped with a function of inputting one or a plurality of search rules, searching for an item value according to the input one or a plurality of search rules, and executing a process of acquiring the value. An engine that generates based on one or more input search rules and outputs the generated parser PS is installed. In step SD2, the control server control unit 40 generates a parser PS by the function of the engine.
For example, it is assumed that the search rule acquired in step SD1 is a search rule corresponding to the rule information JH18a. In this case, in step SD2, the control server control unit 40 is one line to the right of the keyword (in this example, the keyword "TOTAL:") that appears first (uppermost) in the printed text data. Generates a parser PS equipped with a function to acquire the information located in as an item value.

In particular, the parser PS performs the following processing when searching for an item value based on the positional relationship between the keyword and the item value in the printed text data. That is, first, the parser PS identifies the position of the keyword in the printed text data by the character string search. As will be described later, when a plurality of character strings corresponding to the keywords are described in the print text data, the keywords to be used for searching the item values are specified according to the processing rules. Next, the parser PS specifies the position of the item value (searches for the item value) based on the keyword whose position is specified and the positional relationship between the keyword and the item value.
In this way, the parser PS uses the character string search to specify the position of the keyword in the printed text data. Therefore, the keyword is required to be exactly the same as the character string described in the printed text data. In the present embodiment, as described above, the user can specify a keyword that is exactly the same as the character string described in the print text data by a simple operation.

Next, the control server control unit 40 displays the analysis result confirmation screen G424 in the second area A42 (step SD3).
Next, the control server control unit 40 analyzes the text data to be processed by the function of the newly generated parser PS, and displays the analysis result on the analysis result confirmation screen G424 of the second area A42 (step SD4).

FIG. 24 shows the fourth user interface UI 4 in a state where the analysis result confirmation screen G424 is displayed in the second area A42.
The user can confirm the validity of the analysis result of the newly generated parser PS by confirming the content of the analysis result confirmation screen G424. That is, the user refers to the text display screen G43 of the third area A43, recognizes the correct item value to be acquired by the parser PS, and validates the analysis result of the parser PS newly generated based on the recognition. You can check it. The user determines that the analysis result of the parser PS is valid when the correct item value is displayed on the analysis result confirmation screen G424, and when the value other than the correct item value is displayed, the parser PS Determine that the analysis result is not valid.
As shown in FIG. 24, the analysis result confirmation screen G424 includes an overwriting button UB instructing the application of the newly generated parser PS and a cancel button CC for canceling the application of the newly generated parser PS. Has. The user confirms the contents of the analysis result confirmation screen G424, determines whether the analysis result of the newly generated parser PS is valid, operates the overwrite button UB if it is valid, and cancels the button if it is not valid. Operate CC.

As shown in the flowchart FD of FIG. 23, after displaying the analysis result of the newly generated parser PS on the analysis result confirmation screen G424, the control server control unit 40 monitors whether or not the cancel button CC has been operated. At the same time (step SD5), it is monitored whether or not the overwrite button UB is operated (step SD6).
When it is detected that the overwrite button UB has been operated (step SD6: YES), the control server control unit 40 executes the following processing (step SD7). That is, in step SD7, the control server control unit 40 refers to the parser management database 421, and newly generates a parser PS corresponding to the selection receipt item associated with the serial number J11 of the selection printing device in the database. It is overwritten and updated by the parser PS.
As a result of the process of step SD7, when the control server control unit 40 receives the print text data from the selective printing device, the process of acquiring the item value for the selected receipt item is based on the function of the newly generated parser PS. And execute.
Next, the control server control unit 40 closes the analysis result confirmation screen G424 (step SD8).

On the other hand, when it is detected that the cancel button CC has been operated (step SD5: YES), the control server control unit 40 shifts the processing procedure to step SD8 without updating the parser management database 421, and the analysis result. Close the confirmation screen G424.

When a record is registered in the parser management database 421 for the printing device 12, each of the parser PSs associated with the serial number J11 of the printing device 12 is the default parser PS prepared in advance. Will be done.

<Second total amount information frame>
FIG. 25 is a diagram showing a step-corresponding screen G423 that transitions from the frame selection screen G422 after the second total amount information frame is selected on the frame selection screen G422 of FIG. The second total amount information frame has a plurality of steps.
On the step correspondence screen G423 of FIG. 25, it is possible to input a keyword used when searching the item value (total amount information J92 in this example) of the selected receipt item (total amount information item in this example). It is possible. The user uses the text display screen G43 to select a keyword word or word group by the method described above. As a result, the user specifies a search rule that the keyword is a predetermined word or word group.

The step correspondence screen G423 of FIG. 25 includes a step correspondence screen G423 that can be transitioned next. Based on this, the confirmation button CB is not displayed on the step correspondence screen G423 of FIG. 25, and the transition button NB instructing the transition to the next step correspondence screen G423 is displayed.
When it is detected that the transition button NB has been operated, the control server control unit 40 transitions to the next step correspondence screen G423.

FIG. 26 is a diagram showing a step correspondence screen G423 displayed in place of the step correspondence screen G423 of FIG. 25 when the transition button NB of the step correspondence screen G423 of FIG. 25 is operated.
On the step correspondence screen G423 of FIG. 26, seven rule information JH26a to rule information JH26g are displayed in a list that can be selected according to the positional relationship between the keyword and the item value to be searched. The user refers to the text display screen G43 and selects the rule information corresponding to the appropriate search rule from the rule information JH26a to the rule information JH26g.

Of the rule information JH26a to the rule information JH26g, the rule information JH26c will be described below.
Rule information JH26c is rule information indicating a search rule that specifies that the item value corresponding to the selected receipt item is the Nth word from the left (N is a positive integer) in the same line as the keyword. .. The Nth word in the "line" of 1 means the following. That is, the Nth word in the "line" of 1 is the word located in the Nth position from the left when the words described in the "line" of 1 are counted in order from the left excluding whitespace characters. Means. For example, in the fourth line of the printed text data T2 of FIG. 6B, words are described in the order of the word "Beer", the word "1", and the word "10.00" except for whitespace characters. In this case, the word "Beer" is the first word, the word "1" is the second word, and the word "10.00" is the third word. The word "10.00" is also the last word in the fourth line of the printed text data T2.

FIG. 27 is a diagram showing a step correspondence screen G423 when a search rule corresponding to the rule information JH26c is selected by a radio button on the step correspondence screen G423 of FIG. 26.
As shown in FIG. 27, when the rule information JH26c is selected, the number display area BA is formed at the lower part of the step correspondence screen G423. The number display area BA is an area that allows the user to select the Nth value and displays the Nth value selected by the user when the search rule selected by the user requires the information of the Nth. .. In FIG. 27, the value of the number selectively displayed in the number display area BA may be a value corresponding to the number of words existing in one line.
In this way, when the search rule requires the information of the Nth, the control server control unit 40 causes the user to select the Nth and forms a number display area BA for displaying the selected Nth value. ..

As shown in FIG. 27, the number display area BA has an input field N27a. The Nth value can be input to the input field N27a by selecting the Nth value from the pull-down menu. The user inputs the Nth value in the input field N27a by selecting an appropriate value from the pull-down menu corresponding to the input field N27a.
As shown in FIG. 27, in the present embodiment, the user can select "last" and "second from last" as the Nth value in addition to the first to fifth values. This is based on the fact that a predetermined item value may be described as "last" or "second from last" in a predetermined "line".

As described above, in the present embodiment, the user can easily describe the predetermined item value in the printed text data according to the rule that the predetermined item value is located at the Nth position in the predetermined "line". You can work and specify search rules that correspond to such rules.

Regarding the step correspondence screen G423 shown in FIG. 27, the user selects one search rule from the search rules corresponding to the seven rule information JH26a to the rule information JH26g, and uses the number display area BA as necessary to be the Nth. After selecting the value of, operate the transition button NB to confirm the specification of the search rule. When it is detected that the transition button NB has been operated, the control server control unit 40 transitions to the next step correspondence screen G423.

FIG. 28 shows the case where the transition button NB is operated after the search rule corresponding to the rule information JH26c is selected and "last" is selected as the Nth value on the step correspondence screen G423 of FIG. 27. It is a figure which shows the step correspondence screen G423 which is displayed instead of the step correspondence screen G423 of 27.
The step correspondence screen G423 of FIG. 28 shows that when a plurality of keywords set by the user are described in the print text data, the keyword used for searching the item value appears at the Nth position in the print text data. This is the screen for specifying search rules.
Here, in the printed text data, a plurality of character strings used as keywords may be described. For example, when the character string "TOTAL" is used as a keyword, the subtotal explicit information J71 and the total amount explicit information J91 both include the character string "TOTAL", and as a result, the characters are included in the printed text data. A plurality of columns "TOTAL" may be described. Even in such a case, since the character string that can be used as a keyword is described according to the rule corresponding to the layout of the receipt, the desired keyword can be specified by specifying that the keyword appears Nth. It is possible.

The step correspondence screen G423 of FIG. 28 has an input field N28a. The Nth value can be input to the input field N28a by selecting the Nth value from the pull-down menu. The user inputs the Nth value in the input field N28a by selecting an appropriate value from the pull-down menu corresponding to the input field N28a.
As shown in FIG. 28, in the present embodiment, the user can select "last" and "second from last" as the Nth value in addition to the first to fifth values. This is because the position of a predetermined keyword may be appropriately specified by specifying that it appears "last" or "second from last". In FIG. 28, the value of the number selectively displayed in the number display area BA may be a value corresponding to the number of words corresponding to the keywords appearing in the printed text data.
The step-corresponding screen G423 shown in FIG. 28 is the last step-corresponding screen G423 of the step-corresponding screens G423 corresponding to the selection frame (in this example, the second total amount information frame). Regarding the step correspondence screen G423 shown in FIG. 28, the user inputs the Nth value in the input field N28a by using the pull-down menu. After inputting into the input field N28a, the user operates the step confirmation button SB or the confirm button CB. The processing of the control server control unit 40 when any of these buttons is operated is as described above.

As described above, in the present embodiment, the user can easily describe a plurality of character strings specified as keywords in the printed text data according to the rules corresponding to the layout of the receipt. You can work and specify search rules that correspond to such rules.

<5th parser PS5>
A case where the fifth parser PS5 is generated will be described.
When generating the fifth parser PS5, the user selects a cancellation presence / absence information item (property "is_voice") on the item selection screen G41.
The property "is_voice" (cancellation presence / absence information item) is a property of data type: boolean, and is different from the property "total" (total amount information item) in that respect.
As described above, the accounting may be canceled, and in that case, the printed text data based on the receipt issued by the accounting is referred to as information indicating that the cancellation has been made (hereinafter, "cancellation explicit information J28". ) Is described. When the cancellation explicit information J28 is described in the print text data, the item value of the cancellation presence / absence information item becomes a true value, and when the cancellation explicit information J28 is not described, the item value of the cancellation presence / absence information item is It becomes a false value.
Data type that takes either a true value or a false value depending on whether or not predetermined information is described in the print text data: Generation of a parser PS having a function of searching a receipt item corresponding to a Boolean property. At that time, the control server control unit 40 executes the following processing.

FIG. 29 is displayed in the second area A42 when the cancellation presence / absence information item is selected on the item selection screen G41 and the parser generation start button QB is operated on the acquisition item value display screen G421 related to the cancellation presence / absence information item. It is a figure which shows the frame selection screen G422.
Regarding the cancellation presence / absence information item, the number of corresponding frames is one. The user confirms the frame selection by operating the frame confirmation button XB displayed on the frame selection screen G422 related to the cancellation presence / absence information item. When it is detected that the frame confirmation button XB has been operated, the control server control unit 40 transitions the frame selection screen G422 to the step correspondence screen G423.

FIG. 30 is a diagram showing a step correspondence screen G423 transitioning from the frame selection screen G422 of FIG. 29. The frame related to the cancellation presence / absence information item has one step.
On the step correspondence screen G423 of FIG. 30, it is possible to input a keyword to be used when acquiring the item value of the selected receipt item (in this example, the cancellation presence / absence information item). In the case of the cancellation presence / absence information item, the keyword is the cancellation explicit information J28.
The user specifies a search rule that the keyword is a predetermined word or word group by the step correspondence screen G423 of FIG. 30.
When the cancellation explicit information J28 is described in the processing target text data in which the text is displayed on the text display screen G43, the user selects a word or a word group as a keyword by the method described above.
On the other hand, when the cancellation explicit information J28 is not described in the processing target text data in which the text is displayed on the text display screen G43, the user specifies the search rule by the following method. When the accounting is canceled, the user recognizes the cancellation explicit information J28 printed on the receipt by a predetermined means, and inputs a character string representing the cancellation explicit information J28 by using a keyboard or the like.
The keyword input by the user is displayed in a predetermined area of the step correspondence screen G423.

With respect to the step correspondence screen G423 shown in FIG. 30, the user operates the step confirmation button SB or the confirm button CB after inputting a keyword. The processing of the control server control unit 40 when any of these buttons is operated is as described above.
