Control unit 10 includes：Number image cut-out portion 10a, cut out from the banknote image being input into by identification part 2 including number The parts of images in the region of code；Character picture cut-out portion 10b, cuts out everybody word to form number from the number image for cutting out Symbol image；Character recognition part 10c, the character recognition based on pattern match is carried out using character picture and is processed；And number is determined Determine portion 10d, the result of character recognition based on character recognition part 10c treatment determines number everybody character.Additionally, control unit 10 also include：Processing attribute determination section 10e, recognition result based on the bank note obtained by identification part 2 and by number determination section The character identification result of the number that 10d is obtained, determines the processing attribute of bank note；And transmission control unit 10f, based on by treatment category Property the processing attribute that determines of determination section 10e, control the transfer destination of bank note.
Number information 20a, character recognition template 20b and processing attribute set information are saved in storage part 20 20c.In number information 20a, including represent the positional information in printing position of the number 101 in banknote image 100, expression number The character attibute information of everybody character attibute of code, the set information of character identification result for determining number etc..Additionally, In character recognition with template 20b, including the template data used for carrying out everybody character recognition of number.According to shape Prepare template data into the character attibute of number.Additionally, in processing attribute set information 20c, saving and entering to bank note Grade when line character is recognized and the set information needed for for determining processing attribute etc..
Fig. 4 is the example for representing the banknote image, number image and character picture that are obtained by bank note treatment device 1 Figure.Such as Fig. 4（a）It is shown, the banknote image 100 including number 101 is obtained by identification part 2.Number image cut-out portion 10a is based on knowing The cash category identification result in other portion 2, the coordinate of number 101 is determined with reference to the number information 20a preserved in storage part 20. Then, such as Fig. 4（b）It is shown, the parts of images for including number 101 is cut out as number image 102.Then, such as Fig. 4（c） Shown, character picture cut-out portion 10b separates everybody character picture 103 from number image 102.Then, character recognition part 10c profits The character recognition template 20b preserved in storage part 20, carries out the character of character included in each character picture 103 Identifying processing.On these treatment, for example, it is documented in No. 4377589 publications of Japanese Patent Publication No. of present applicant, institute To omit detailed description.
External memory 30 is that USB storage etc. can be to the storage device of the handling of bank note treatment device 1.External storage is filled Put 30 numbers determined by number determination section 10d for the result of the character recognition treatment of character recognition part 10c will to be received Character identification result, preserves as number data 30a.On the details of data that is preserved as number data 30a rear Face describes, but by capacity for the storage device of 2G bytes can preserve about 17,000,000 numbers of bank note.In addition, as outer Portion's storage device 30, it is also possible to filled using the storage that be connected to control unit 10 and can be communicated between control unit 10 Put.
[character recognition processing method]
Hereinafter, the result of the treatment of the character recognition based on character recognition part 10c is illustrated to determine as number data 30a The treatment of everybody character of the number of preservation.The treatment is the treatment carried out by number determination section 10d.First, illustrate and make The setting content relevant with the reading process of number set with display operating portion 3.
Fig. 5（a）It is the example of the setting screen of reading process about number." number record " in setting screen In, whether the reading and preservation for carrying out number can be set.Additionally, in " ambiguous position shows ", in character identification result, The position of number is formed as that in the case of ambiguous position, can select to be to show all ambiguous positions with error character, is also used in The candidate characters obtained in character recognition treatment show all ambiguous positions, according further to condition selection error character or One of them in candidate characters shows all ambiguous positions.In " error character rate ", being set as with error character or In the case that one of them in candidate characters is to show ambiguous position, raising can be set or reduction is shown with error character Ambiguous position.Additionally, in " error character is specified ", the species of the character used as error character can be specified.Here, wait Word selection is accorded with, character being processed by character recognition and obtained, there is a possibility that the character for turning into process object.This Outward, ambiguous position refers to, although is processed by character recognition and obtains candidate characters, but there is no the character of process object just It is the position of the sufficient reliability of candidate characters.In addition, in " error character specify ", except shown in Fig. 5 " _（Underscore）” Outside, additionally it is possible to specify "" etc. other characters.
Set and whether ambiguous position is shown using error character thereby, it is possible to be shown as ambiguous position.It is being set as using In the case that error character is to show ambiguous position, preassigned error character is all used in ambiguous position in character identification result To show.Additionally, in the case where being set as showing ambiguous position with character identification result, the ambiguous position in character identification result All shown with candidate characters.
Then, the situation for being set as showing ambiguous position using one of them in error character or candidate characters is illustrated Under treatment.Fig. 6 is to illustrate be set as showing ambiguous position using one of them in error character or candidate characters In the case of, the figure of the determining method of character identification result.Everybody character recognition treatment of number is by character recognition part 10c Carry out.Specifically, character recognition treatment is carried out with the pattern match of template 20b by using character recognition.The longitudinal axis of Fig. 6 Represent the matching degree of the uniformity between the character picture and template obtained from bank note.The setting of the matching degree is set to Adapted threshold value.If the matching degree between the character for being processed by character recognition and being obtained and template has exceeded matching threshold value, Number determination section 10d determines character identification result, and the character of acquisition is set to determine character.That is, right side table of the matching degree in Fig. 6 When in the scope of the region X for showing, character identification result is determined.
For example, as shown in fig. 6, the 1st is English alphabet A by character recognition, and when the matching degree is in the X of region, then The character identification result of the 1st is confirmed as English alphabet A.That is, the character identification result of the 1st turns into determination character A.Separately Outward, in actual character recognition treatment, it is considered to and the difference of the matching rate of other templates etc. and processed, but in this implementation In example, the detailed description on character recognition treatment, the content needed for only recording the explanation of the present embodiment are omitted.
Error character judgement threshold value is set to less than the setting of matching threshold value.In the knot of character recognition treatment Really, matching degree is less than matching threshold value, so in the case of not can determine that character identification result, the position turns into ambiguous position.Also, In the case where matching degree is the value higher than error character judgement threshold value, by number determination section 10d by character identification result The candidate characters of the acquisition in character identification result are determined into show ambiguous position.On the other hand, it is less than mistake in matching degree In the case of character judgement threshold value, character identification result is determined into error character to show ambiguous position.That is, in matching degree When on the right side of Fig. 6 in the scope of shown region Y, ambiguous position is shown with character identification result, and when in the Z of region, with mistake Character is missed to show ambiguous position.
For example, as shown in fig. 6, due to the matching degree of the 7th in the Y of region, the matching degree of the 10th in the Z of region, institute All it is ambiguous position with the 7th and the 10th.Because the 7th is numeral 5 by character recognition, and the matching degree is in the Y of region, so The 7th is shown as numeral 5 in character identification result.In contrast, due to the 10th by character recognition for numeral 8, but should Matching degree is in the Z of region, so showing the 10th with error character in character identification result.
Fig. 5（a）Setting screen in the setting of height of error character rate be that the error character shown in setting Fig. 6 is sentenced Surely the setting of the height of threshold value is used.If in Fig. 5（a）Setting in error character rate is set to height, then error character judge use The value of threshold value is set high, shows that the possibility of ambiguous position is improved with error character.If additionally, error character rate is set Must be low, then the value of error character judgement threshold value is set low, using in character identification result obtain candidate characters come Show that the possibility of ambiguous position is improved.
Additionally, the setting of error character rate is, in addition to the height of error character judgement threshold value, also set for sentencing Fixed 2 distances of candidate characters（The difference of matching degree）Range estimation threshold value（The threshold value of the difference of matching degree）The setting of L1.Tool Say body, as shown in fig. 6, due to the candidate characters as the 1st of the 2nd English alphabet B matching degree in the Y of region, As the candidate characters of the 1st of the 3rd numeral 1 matching degree in the Y of region, so the 2nd and the 3rd is all ambiguous Position.In the result that the character recognition of the 2nd is processed, the English alphabet B as the candidate characters of the 1st and the time as the 2nd The numeral the distance between 8 of word selection symbol（The difference of matching degree）L2 be the range estimation threshold value L1 that is set with error character rate with In the case of upper, in character identification result, the ambiguous position of the 2nd is shown as English alphabet B.In contrast, at the 3rd The result of character recognition treatment, the English alphabet I of the candidate characters as the numeral 1 of the candidate characters of the 1st and as the 2nd The distance between（The difference of matching degree）In the case that L3 is less than range estimation with threshold value L1, the 3rd is shown with error character Ambiguous position.That is, even if the matching degree of number determination section 10d candidate characters of the 1st of acquisition in character recognition treatment is in area In the case of in the Y of domain, in the candidate characters of the 1st and the distance of the candidate characters of the 2nd（The difference of matching degree）Less than setting in advance In the case that fixed range estimation is with threshold value L1, ambiguous position is still also shown with error character.If by the setting of error character rate It is high, then the value of L1 be set to it is larger, shown with error character ambiguous position possibility improve.If additionally, by erroneous words Symbol rate be set to it is low, then the value of L1 be set to it is smaller, shown using character identification result ambiguous position possibility improve.
Thus, by the way that the display of ambiguous position can be set in about the setting for relaxing judgement in using only erroneous words Symbol, or use candidate characters to leave the information of character identification result such that it is able to carry out the fortune with the user of device With corresponding setting.Additionally, by addition to showing the whole of ambiguous position by error character or candidate characters, moreover it is possible to Enough is the probability that probability, the i.e. character identification result of candidate characters is correct result according to ambiguous position, select error character or Person's candidate characters show, so can also only using the possibility of correct character identification result ambiguous position high as candidate word Symbol.In addition, for judging to sentence using which the error character judgement threshold value and distance in error character or candidate characters Surely threshold value is used（The threshold value of the difference of matching degree）, can be changed according to the setting of display operating portion 3.
In the case where ambiguous position is shown with error character, can recognize that this is ambiguous position according to display content Situation.But, in the case that the candidate characters obtained in used in character identification result are to show ambiguous position, due to this conduct Numeral or English alphabet show, so the situation of the result for being to determine character identification result or ambiguous position can not be recognized. For the such situation of correspondence, in bank note treatment device 1, in addition to everybody character identification result of number, also preserve For represent everybody whether be ambiguous position ambiguous position information, so as to learn be ambiguous position situation.
Fig. 7 ~ Figure 10 is the figure of the example of the character identification result and ambiguous position information for representing number.The epimere of figure is number Character identification result, hypomere is ambiguous position information.Numeral in everybody upside of number represents position number.Ambiguous position information Formed by everybody the corresponding numeral with number, the 0 of numeral is distributed in the case where character identification result is not ambiguous position（Zero）, The 1 of numeral is distributed in the case where character identification result is ambiguous position.Wherein, the content of ambiguous position information is not limited to this, As long as ambiguous position and other positions can be distinguished, then can also be to the numeral of each bit allocation more than two, it is also possible to distribute Character beyond the numeral such as English alphabet.
Fig. 7 represents the result of the character recognition treatment of character recognition part 10c, character knowledge is determined in whole positions of number The example of the character identification result in the case of other result.Thus, in the case of not including ambiguous position in character identification result, Whole positions of ambiguous position information turn into 0（Zero）.
Fig. 8 represents that the 2nd, the 3rd, the 7th and the 10th is known by the character shown in Fig. 6 that character recognition is ambiguous position The example of other result.In the setting that ambiguous position shows, be set as with error character " _（Underscore）" show the complete of ambiguous position Example in the case of portion is Fig. 8（a）, it is set as being used in the candidate characters of acquisition in character identification result to show ambiguous position Example in the case of whole is Fig. 8（b）.
Such as Fig. 8（a）It is shown, in the case where being set as being shown with error character the whole of ambiguous position, with erroneous words Symbol is come in showing the position of character identification result, ambiguous position information is shown as 1.Such as Fig. 8（b）It is shown, it is being set as using candidate word Symbol come in the case of the whole for showing ambiguous position, according only to the character identification result of number, it is impossible to judge whether to include ambiguous position And which position is ambiguous position in the case where including.But, by using ambiguous position information, it is capable of identify that ambiguous position information is 1 position is ambiguous position.Additionally, now, in addition to being the situation of ambiguous position, additionally it is possible to which acquisition is obtained as character identification result The numeral or the information of English alphabet of the candidate characters for obtaining.
Fig. 9 is showing the figure of the character identification result shown in Fig. 6.Wherein, Fig. 9 be in the setting that ambiguous position shows, It is set as one of them according to condition selection error character or the candidate characters obtained in character identification result To show the example in the case of ambiguous position.In addition, it is assumed that the 2nd and the 1st of the 3rd and the candidate of the 2nd shown in Fig. 6 The distance of character（The difference of matching degree）L2 and L3 and as whether shown with error character ambiguous position determinating reference away from From decision threshold（The threshold value of the difference of matching degree）L1 has L3<L1<The relation of L2.Now, the character identification result of the 2nd turns into English alphabet B, the character identification result of the 3rd turns into error character.Further, since the 7th in the Y of region, so character is known Other result turns into numeral 5, because the 10th in the Z of region, so character identification result turns into error character.
As a result, as shown in figure 9, despite the ambiguous position of identical, but in the 2nd and the 7th, using candidate characters It is shown as English alphabet B and numeral 5.In contrast, the 3rd and the 10th is shown with error character.Now, the 2nd and the 7th The character identification result of position will not also be shown with error character but be shown with candidate characters, so only seeing character recognition knot Really, it is impossible to which it is ambiguous position to identify whether.But, according to ambiguous position information, it is capable of identify that the position for being shown as 1 is ambiguous position.
In addition, changing the ambiguous position in character identification result based on the matching degree of template when being processed with character recognition Display method, be not limited to as shown in Figure 9, selection error character or candidate characters the mode that shows.For example, It is equally possible that be based on matching degree come the judgement for carrying out ambiguous position while do not use error character and show character recognition The mode of result.
Specifically, as shown in Figure 10, do not use error character and use candidate characters and replace error character, display with Fig. 9 identical character identification results.Also, distinguish ambiguous position information and shown, although so as to recognizing all be identical Ambiguous position, but result of determination about matching degree in the 2nd and the 7th, the 3rd and the 10th is different.In Fig. 10, exist Equally it is being ambiguous position but as candidate word to ambiguous position information distribution numeral 2 in as the 3rd of ambiguous position and the 10th In the 3rd and the 10th high the 2nd of the likelihood ratio of symbol and the 7th, distribution numeral 1, so as to make a distinction.That is, in Fig. 9 Example in the ambiguous position of shown with error character the 3rd and the 10th, character recognition knot is also shown with candidate characters While fruit, the numeral to the distribution of ambiguous position information is changed to be made a distinction with other ambiguous positions.
Thus, even in the case of the ambiguous position of identical, also as shown in fig. 6, in character identification result The matching degree of the candidate characters of value, the 1st and the 2nd with degree away from（The difference of matching degree）From, separably show character know Other result, so as in the ambiguous position of identical, it is also possible to candidate characters are left as information as correct character recognition knot The different situation of the probability of fruit.
Specifically, as shown in fig. 6, the 7th high for the probability that the likelihood ratio the 10th of numeral 5 is numeral 8.Due in figure In 10,2 as ambiguous position information 1 to the 7th bit allocation, to the 10th bit allocation, it is possible to the such situation of identification.Together Sample ground, can recognize that the likelihood ratio the 3rd that the 2nd is English alphabet B is the probability of numeral 1 feelings high based on ambiguous position information Condition.That is, except can interpolate that ambiguous position information be 0 in addition to position for outside ambiguous position, additionally it is possible to judge that in ambiguous position information be 1 In the case of compared with ambiguous position information is 2 situation, the correct possibility of shown character identification result is high.
In bank note treatment device 1, the number for so determining is stored in external memory 30 as number data 30a In.In external memory 30, the file using date-time as folder name is automatically generated.Also, in file It is interior, the Number Reorganization result of bank note is saved by each trading post point filename.
Figure 11 is the figure for illustrating file and file in external memory 30.Thus, distinguished according to date-time File, and when bill handling has been carried out, file is generated with the filename based on date-time.For example, at 1 day 2 months 15 The number of the treatment that point starts for 00 second 30 minutes is preserved with the filename of " 0201153000 ".Additionally, for example in the feelings of income treatment Under condition, as only with the filename of date-time, and in the case where envelope band is being carried out, be addition of as the beginning in filename The filename of English alphabet W, so as to be based on each filename to judge the content of bill handling.If thus generating file, Then preserve a number data for whole bank note for the treatment of.Each file is for example generated with csv forms.
Figure 12 is the figure of the example for representing the data preserved in each file.Thus, hereof, each bank note is remembered The number of the order for representing processed is recorded（No.）, processed moment, the denomination of bank note（Cash species）, represent bank note The word of the certificate kind of complete damage, the transfer destination information deposited in bank note treatment device, the number determined by number determination section 10d Accord with recognition result and ambiguous position information, whether there is ambiguous position information.Here, it is to represent whether number includes to whether there is ambiguous position information The information of ambiguous position.In the case of not including ambiguous position in the character identification result of number, 0 is shown as（Zero）, and at least In the case of including an ambiguous position, 1 is shown as.
Figure 13 be represent display operating portion 3 on show the information preserved as number data 30a in the case of The figure of the example of picture.On picture, it is shown that the information for being recorded in each file as shown in Figure 12.Additionally, drawing On face, on whetheing there is ambiguous position information, shown with character whether include ambiguous position, so as to be readily appreciated that display number Whether code includes ambiguous position.Additionally, ambiguous position information is based on, to enclose the ambiguous position of offline status display, so that basis exists The number shown in picture is just understood that the position of ambiguous position.
In addition, the display methods of number is not limited to this, as long as ambiguous position and other positions can separably be shown, Then can also be with the ambiguous position of the status display surrounded with bracket, it is also possible to change color and show ambiguous position and other positions.
Additionally, the store method on number data 30a, as long as can leave for determining bill handling and in the bank note The information of the bank note processed in treatment, then folder name, filename and file format etc. are not particularly limited.Additionally, each In the information preserved in individual file, as long as the character identification result and ambiguous position information of number can be left, then in addition wrap The information for including is not particularly limited.
Additionally, in the present embodiment, illustrating the word of the identification of the species of bank note, the acquirement of banknote image and number The mode for all being carried out by bank note treatment device 1 of identifying processing is accorded with, but the present embodiment is not limited to this.Specifically, Can construct number by the terminal of bank note treatment device 1 and the computer installation for being connected to bank note treatment device 1 etc. to read system System, about the mode that the function of number reading process is performed with least a portion of action in terminal.For example, in bill handling The identification of the species of the acquirement and bank note of banknote image, reason at others are only carried out in device 1, or by identification part 2 It is connected to the mode that the terminal of bank note treatment device 1 is carried out.I.e., or above-mentioned display operating portion 3, control unit 10, deposit The mode that the function of storage portion 20 and external memory 30 and action are realized in the terminal of bank note treatment device 1 is connected to. In addition, between bank note treatment device 1 and terminal, in addition to the mode of wired connection, or wireless connection mode. In addition it is also possible to be the external storage dress of the USB storage that both can be utilized using bank note treatment device 1 and terminal etc. Put and enter the mode of the exchange of row information.
As described above, according to the present embodiment, processed by character recognition and identify the number of paper result be containing In the case of paste position, can select to be shown with error character, also be used in the candidate characters obtained in character identification result To show.Even additionally, ambiguous position, it is also possible to shown using character identification result such that it is able to left as information Character identification result.
Further, since generate obtained for being denoted as character identification result everybody whether be ambiguous position ambiguous position Information, and the both sides of ambiguous position information and character identification result are preserved, even so that the acquisition in character identification result In the case that candidate characters are to show ambiguous position, it is also possible to recognize whether everybody is ambiguous position.
[embodiment 2]
Then, the paper processing device that present invention will be described in detail with reference to the accompanying.In the present embodiment, as paper it One bank note is process object, illustrates that the bank note treatment device acted as paper processing device is carried out for recognizing each paper The intrinsic information of coin is that the character recognition of number processes the example of the situation of the bank note.In addition, in the present embodiment, using Institute sharp used figure is illustrated in embodiment 1.Fig. 1 of embodiment 1 ~ content illustrated in fig. 4 also can in the present embodiment It is enough to share, but due to as described above, therefore the description thereof will be omitted.Hereinafter, in being with the difference of the present embodiment and embodiment 1 The heart, the explanation needed for carrying out understanding the present embodiment.
By the way that with the structure shown in Fig. 1 ~ Fig. 3, bank note treatment device 1 can shoot bank note and obtain banknote image, profit Character recognition is carried out to the number printed on bank note with the banknote image.When carrying out character recognition and processing, can be from logical Often judge to select character recognition grade in the character recognition grades different with relax judgement two kinds.
Generally judge it is the character recognition treatment for carrying out in the past, specifically, carried out at number everybody character recognition Reason, the method for the bit allocation error character to not can determine that character identification result.That is, in generally judging, to there is multiple to turn into The candidate characters of the candidate of character identification result are without can determine that the ambiguous position of character identification result and cannot get candidate characters The both sides' assignment error character that can not recognize position without can determine that character identification result.
In contrast, it is to carry out character recognition treatment to being assigned with the position of error character in the past to relax judgement so that leave About the method for the information of character identification result.In the case where judgement is relaxed, character is not can determine that from multiple candidate characters The character identification result of the ambiguous position of recognition result turns into the candidate characters of the 1st.Even in addition, relaxing the situation of judgement Under, to cannot get candidate characters can not recognize position also or with generally judge when it is identical ground assignment error character.
Due to the usual character recognition treatment for judging method present applicant No. 4377589 public affairs of Japanese Patent Described in report, so detailed description is omitted, below, the method that the character recognition treatment in judging is relaxed in detailed description.
【Relax the character recognition processing method of judgement】
Hereinafter, character recognition treatment when illustrating to relax judgement.This treatment is utilized and obtained by character recognition part 10c As a result, the treatment for being carried out by number determination section 10d.First, illustrate using showing the setting for relaxing judgement that operating portion 3 is carried out.
Fig. 5 is the example of the setting screen for relaxing judgement.In " ambiguous position shows " in setting screen, can set by Ambiguous position all shown with candidate characters, and one of them in error character or candidate characters is selected according further to condition To show.In " error character rate ", it is being set as showing ambiguous with one of them in error character or candidate characters In the case of position, raising can be set or reduction shows the possibility of ambiguous position with error character.Additionally, in " erroneous words Symbol is specified " in, the species of the character used as error character can be specified.In addition, candidate characters refer to, known by character Character that other places are managed and obtained, that there is the character for turning into process object.Additionally, ambiguous position refers to, although pass through Character recognition is processed and obtains multiple candidate characters, but there is no the character of process object is exactly the sufficient of candidate characters Reliability, so as to the position of character identification result can not be determined.
Thus, in bank note treatment device 1, can set and whether be shown as ambiguous position and shown using error character Ambiguous position.In the case where being set as only showing ambiguous position with candidate characters, the ambiguous position profit of whole in character identification result The candidate characters that are used as character identification result and obtain show.In contrast, being set as the profit in the display of ambiguous position In the case of with error character, ambiguous position is shown with preassigned error character or candidate characters.In addition, if use Error character shows the determining method etc. of ambiguous position as reference picture 6 in embodiment 1 and Fig. 7 explanations, therefore omits it Explanation.
Fig. 8 represents that the 2nd, the 3rd, the 7th and the 10th is known by the character shown in Fig. 6 that character recognition is ambiguous position The example of other result.Carried out it is usual judge in the case of example be Fig. 8（a）, it is set as being used in word in judgement is relaxed The candidate characters obtained in symbol recognition result are Fig. 8 come the example in the case of the whole for showing ambiguous position（b）.
Such as Fig. 8（a）It is shown, in the case where generally judging, in the position for showing character identification result with error character, Ambiguous position information is shown as 1.Such as Fig. 8（b）It is shown, it is set as showing the complete of ambiguous position with candidate characters in judgement is relaxed In the case of portion, according only to the character identification result of number, it is impossible to judge whether to include ambiguous position and in the case where including Which position is ambiguous position.But, by using ambiguous position information, it is capable of identify that the position that ambiguous position information is 1 is ambiguous position.This Outward, now, in addition to being the situation of ambiguous position, additionally it is possible to obtain the number of the candidate characters obtained as character identification result The information of word or English alphabet.
Fig. 9 is showing the figure of the character identification result shown in Fig. 6.Wherein, Fig. 9 is shown in the ambiguous position for relaxing judgement Setting in, be set as according to condition selection error character or the candidate characters obtained in character identification result One of them shows the example in the case of ambiguous position.In addition, it is assumed that the 2nd and the 1st and the 2nd of the 3rd shown in Fig. 6 The distance of the candidate characters of name（The difference of matching degree）L2 and L3 and as whether showing the judgement of ambiguous position with error character The range estimation threshold value L1 of benchmark（The threshold value of the difference of matching degree）With L3<L1<The relation of L2.Now, the character recognition of the 2nd Result turns into English alphabet B, and the character identification result of the 3rd turns into error character.Further, since the 7th in the Y of region, institute Numeral 5 is turned into character identification result, because the 10th in the Z of region, so character identification result turns into error character.
As a result, as shown in figure 9, despite the ambiguous position of identical, but in the 2nd and the 7th, using candidate characters It is shown as English alphabet B and numeral 5.In contrast, the 3rd and the 10th is shown with error character.Now, the 2nd and the 7th The character identification result of position will not also be shown with error character but be shown with candidate characters, so only seeing character recognition knot Really, it is impossible to which it is ambiguous position to identify whether.But, according to ambiguous position information, it is capable of identify that the position for being shown as 1 is ambiguous position.
In addition, carrying out the judgement of the ambiguous position based on matching degree, and error character is not utilized and character identification result is shown Method, the store method of character identification result etc. as 10 ~ Figure 13 of reference picture explanations in embodiment 1, therefore omit it Explanation.
【Bill handling method based on character recognition result】
Then, illustrate after the character recognition treatment for having carried out usual judgement or having relaxed judgement, based on what is obtained Character identification result and the bill handling that carries out.Identification knot based on cash species, the true and false, the complete damage obtained by identification part 2 etc. Fruit and the character identification result of the number obtained by character recognition part 10c and number determination section 10d, carry out the place of each bank note Reason.In addition, it is following, for the purpose of simplifying the description, it is assumed that in Fig. 5（b）It is set to ambiguous position in the shown setting for relaxing judgement All as the candidate characters of character identification result.
First, the summary of bill handling is illustrated.Figure 14 is at bank note of the explanation based on recognition result and character identification result The schematic diagram of the summary of reason.Such as Figure 14（a）It is shown, in bank note treatment device 1, can be from generally judging and relax the two of judgement The character recognition grade of number is selected in kind.
Such as Figure 14（a）It is shown, in generally judging, in the case of character identification result being defined as into a character, It is not ambiguous position or in the case of position can not being recognized, the character identification result of this is set to determine character.In contrast, Ambiguous position can not recognize position, and character identification result is set into error character.On the other hand, it is and usual in relaxing and judging The difference of judgement is the candidate for being set to the character identification result of ambiguous position to be obtained as the candidate of character identification result Character.
In bank note treatment device 1, such as Figure 14（a）Shown, can set error character allows digit（N）.Error character It is the threshold value about bill handling to allow digit.Checking numbers, everybody has carried out the result of character recognition, in character identification result Comprising error character digit（n）Digit is allowed in error character（N）With error character digit in the case of below（n）Beyond mistake Character allows digit by mistake（N）In the case of, the processing method change of bank note.In addition, error character digit（n）In usual judgement In the case of turn into ambiguous position and the total of the digit of position can not be recognized, relax judge in the case of turn into the position that can not recognize position Number.
Specifically, such as Figure 14（b）It is shown, by generally judging to have carried out character to the number 101 of banknote image 100 The result of identification, ambiguous position and can not recognize 2 positions of position for error character " _（Underscore）" in the case of, error character position Number turns into n=2.In contrast, in judgement is relaxed, ambiguous position turns into candidate characters rather than error character, can not only recognize Position turns into error character, so error character digit turns into n=1.
According to error character digit（n）Digit is allowed with error character（N）Comparative result, carry out at different bank note Reason.For example, such as Figure 14（c）Shown in epimere, bank note is being obtained for " cash species A by identification part 2（True certificate）And complete certificate " knowledge Other result and error character digit is obtained by character recognition part 10c and number determination section 10d（n）For error character allows position Number（N）In the case of following character identification result（n≤N）, the bank note as cash species A complete certificate, base as in the past It is processed in the setting content in bank note treatment device 1.Specifically, it is set to deposit cash kind for example, being sent to The storage part of the complete certificate of class A.In addition, obtaining error character digit（n）For error character allows digit（N）Following result In the case of, that is, in the case of obtaining the character identification result more than precision of regulation, the character of the number for being obtained is known Other result whether the judgement consistent with the number of preassigned regulation.Specifically, for example, carry out with pre-prepd black In list register number comparison, it is consistent with the number of the counterfeit money included in blacklist etc. in the case of, by the bank note pass It is sent to rejection portion and rejects.
In contrast, such as Figure 14（c）Shown in hypomere, even if obtaining " cash species A by identification part 2（True certificate）And it is complete The identical recognition result of certificate ", but error character digit（n）Digit is allowed beyond error character（N）In the case of（n>N）, it is right The bank note assigns the attributes different from recognition result as processing attribute.Also, carried out at bank note based on the processing attribute Reason.Specifically, such as Figure 14（c）Shown in hypomere, although it has been certificate, the place of the bank note to be identified as cash species A by identification part 2 Reason attribute turns into " cash species A is to damage certificate " or " cash species A is to reject certificate ".Also, the bank note of complete certificate is used as damage certificate Or reject certificate and be processed.In addition, can to set be set to the processing attribute of bank note as outer treatment setting is allowed that certificate is damaged Also it is set to reject certificate.
Here, illustrate to allow outer treatment setting.It is for determining that character identification result is outer to allow to allow outer treatment to set State bank note processing method setting.Bank note is judged to be the condition for allowing outer process object bank note, except mistake Character digit（n）Digit is allowed beyond error character（N）Outside, such as the predetermined bits of also preassigned number are unable to character Matching degree in situation, the character identification result of identification is the 1st time in situation, character identification result below the threshold value of regulation The matching degree of choosing and the 2nd candidate is situation below the threshold value of regulation etc..
Figure 15 is to represent to be set in bank note treatment device 1 to allow the condition of outer process object bank note for determining whether And allow the setting screen example of the outer content for processing setting, allow the figure of the outer setting example for processing setting.In Figure 15（a）Example In son, it is set as carrying out the character recognition of usual judgement and error character digit（n）Allow digit N=2's beyond error character In the case of, it is judged to be outside allowing.
In Figure 15（a）Setting screen in, in the selection project of left-right situs, can select with circle represent it is wireless by Button come select setting.Additionally, in drawing offline selection project in setting screen, expression can be input into arbitrary numerical value or The options purpose situation from multiple projects of list display.For example, as the transfer destination setting for allowing outer treatment setting And " rejection portion " is shown on right side, if but select this, the guide look meeting list display of selectable transfer destination can Arbitrary transfer destination is selected therefrom.
In Figure 15（a）Setting screen in, as outer treatment setting is allowed, be set as in error character digit（n）Exceed Error character allows digit（N）In the case of, using the processing attribute of the bank note as certificate is rejected, it is set for passing based on device Send.For example, in the case of being set as that will reject bank note is sent to rejection portion in the device setting of bank note treatment device 1, mistake Character digit（n）Digit is allowed beyond error character（N）Bank note, even the recognition result in identification part 2 is true certificate and complete In the case of certificate, also serve as rejecting certificate and being sent to rejection portion.That is, will not locate as certificate is rejected in conventional bill handling The bank note of reason is processed as certificate is rejected.
In the case where processing attribute is set as rejecting certificate, the knowledge of cash species is obtained even as true certificate and complete certificate In the case of other result, the amount of money of the bank note will not also reflect the income amount of money.In contrast, being set as damaging certificate in processing attribute In the case of, the amount of money of the bank note is reflected to the income amount of money.Thus, in the case where bank note is determined to be outside permission, use Family can be according to whether wanting for the amount of money reflection of bank note to select processing attribute to the income amount of money.Additionally, on transmission purpose Ground setting, wanting bank note according to the processing attribute of selection in the case of transmitting, can selection device setting and set It is fixed, and in the case where the bank note for wanting to be judged to outside permission is sent to the transfer destination different from setting, can select The transfer destination and set.
Additionally, in bank note treatment device 1, such as Figure 15（a）It is shown, allow outer process object bank note determining whether When, additionally it is possible to specify certain bits.In Figure 15（a）Example in, certain bits specify as "None" without specify certain bits, if but " having " is selected in the setting, then shows the setting screen for specifying certain bits.
Figure 16 is the figure of the example of the setting screen for representing specified certain bits.In figure 16, such as that is shown in upper left quarter Sample, is displayed in the number of the cash species A issued in national X.In setting screen, additionally it is possible to which change draws offline on picture National title and cash kind sector of breakdown, be displayed on the bank note of other issuing countries or cash species print number.
In the case of no specified certain bits in the number of 10, the error character included in whole positions of 10 Number turns into error character digit（n）.For example, allowing digit in error character（N）In the case of being set to N=2, in 10 Which is unrelated, it is allowed to most 2 include error character.
In contrast, as shown in figure 16, if specifying determine object position as certain bits, to mistake in specified position Character digit（n）Counted.In the case of figure 16, the 2nd, the 3rd, 5 of the 8th ~ the 10th is designated as sentencing Determine object position.Therefore, error character digit is counted in this is 5.
Specifically, for example only as determine object position the 3rd character identification result for error character feelings Under condition, error character digit turns into n=1.In contrast, the character identification result of the 4th outside only as determine object is In the case of error character, identically, despite the presence of 1 bit-errors character, but error character digit turns into n=to the situation with the 3rd 0.Thus, for example, can only using important position as determine object position, no matter whether other positions are error character, according only to institute The determine object position specified judges whether bank note is to allow outer process object bank note.
Additionally, as shown in figure 16, additionally it is possible to which being specified as certain bits must recognize position.Position must be recognized is known with character Other result turns into the position for determining character as necessary condition.Must recognize that the character identification result of position is the situation of error character Under, no matter error character digit（n）How, all it is judged to be to allow outer process object bank note.
In the example of Figure 16, the 1st is set to that position must be recognized.Therefore, the character identification result at the 1st is mistake By mistake in the case of character, regardless of other character identification result, the bank note is all judged to it is to allow outer process object Bank note.
In addition, in fig. 14, illustrating and common error character permission digit being set in generally judging and relaxing to judge （N）Example, but in bank note treatment device 1, it is also possible to generally judging and setting different mistakes respectively in relaxing judgement Character allows digit（N）.As a result, for example can be such as Figure 15（b）As shown in set.Thus, set using operating portion 3 is shown Fixed setting content is stored in storage part 20 as a part of sheet properties set information 20c.
Figure 15（a）It is the whole setting screen examples for concentrating the concentration for being set to set to process object bank note, but Can also operating and setting picture bottom detailed setting button and press the bank note such as each issuing country or each cash species each Species is set respectively.
Figure 17 is the figure of the example for representing detailed setting screen.In setting in detail, guide look display bank note treatment device 1 is made It is various bank note of process object, grade or error character can be identified to each bank note allows digit（N）Deng setting. In fig. 17, guide look is displayed in the bank note of cash species A, the cash species B of distribution in national X etc., but can also be by operation Button below national X and select emission of banknotes state, so as to be set in detail to each bank note issued in other countries.
In addition, in fig. 17, the judgement of relaxing of cash species C is set as only being that can not recognize position, and cash species D is put Width judges that it is that ambiguous position and can not recognize position to be set as.This is used to set as error character digit（n）And the position for counting.Putting During width judges, ambiguous position illustrates rather than error character with candidate characters, and only can not recognize position is shown with error character. In Figure 15（a）In shown concentration setting, because the position for there was only error character is used as error character digit（n）And be counted, institute Can not only recognize that position is counted with judgement is relaxed.In the detailed setting shown in Figure 17, sentence in relaxing for cash species C In fixed, similarly, the position of only error character is counted.In contrast, relaxing judgement in the cash species D shown in Figure 17 In, it is impossible to recognize that position and total digit of ambiguous position are set to error character digit（n）.
Specifically, such as Figure 14（b）It is shown, fallen into a trap in the character identification result for relaxing judgement based on concentration setting and miscounted Miss character digit（n）In the case of, the only position of error character（Position can not be recognized）It is counted and turns into n=1.If in contrast, Shown in the cash species D of detailed setting as shown in figure 17, it is set as relaxing the error character digit of judgement（n）Include containing The digit of position is pasted, even if then such as Figure 14（b）As shown in obtain identical character identification result in the case of, as ambiguous position The 3rd also serve as error character digit（n）It is counted and turns into n=2.So, sentenced due to can change to relax by setting The error character digit of timing（n）Count target, user can select correspond to use setting.In addition, by ambiguous position Character identification result be set to candidate characters in the case of, can not be by ambiguous position and other positions even if look at character identification result Make a distinction, so number of bits is counted with reference to ambiguous position information.
In addition, although do not illustrate in fig. 17, but in bank note treatment device 1, generally judging and relaxing judgement Between, can not will only recognize in generally judging position be set to the judgement of object with by can not recognize position and ambiguous position both be set to it is right Between the judgement of elephant, if in the case of the result of determination difference for allowing outer process object bank note, additionally it is possible to will obtain so The bank note of result be sent to the transfer destination of preassigned regulation.Specifically, for example, will judge in judgement is relaxed Judge without being judged to outside allowing and in generally judging, the bank note being judged as outside permission is sent to external stack portion etc. Regulation transfer destination.Thus, the treatment that user can carry out relaxing in judging generally is being sentenced while reaffirming The bank note outside permission is judged as in fixed, or carries out the treatment in generally judging while confirming regulation transmission to be sent to The bank note number of destination and decide whether to be changed to relax judgement.
Due in the detailed setting shown in Figure 17, error character allow the setting content of digit etc. with such as Figure 15（a）Institute The situation of the concentration setting shown is identical, so omitting detailed description.In addition, can be in Figure 15（a）Setting screen in select Based on Figure 15（a）Which in detailed setting shown in shown concentration setting and Figure 17 is set for treatment.Specifically, if Will be in Figure 15（a）Setting screen bottom in be located at the wireless buttons in left side of setting button in detail and be set to effectively, then not analects How is the setting content of middle setting, all carries out based on the character recognition treatment of setting and bill handling in detail.
Then, by taking the setting content of the detailed setting shown in Figure 17 as an example, illustrate to process and carry out using character recognition Allow the bill handling of outer process object bank note.Figure 18 is the recognition result and the paper shown in Figure 17 of the bank note for representing identification part 2 The figure of the relation between the processing attribute of coin.
Processing attribute is to represent the information for how processing bank note.In the result of the identifying processing of identification part 2, belong to as bank note Property and judge cash species, the true and false and complete damage.Additionally, the result of the character recognition to the bank note, decision error character digit （n）For error character allows digit（N）Following " in allowing " and allow digit beyond error character（N）" allow outer " in Which.Also, there is character identification result and be endowed to deal with objects bank note outside the permission of " allow outer " and tied with based on identification The situation of the different processing attribute of the currency note attribute of fruit.
Specifically, as shown in figure 18, it is " cash species A and true certificate and complete certificate ", character identification result in recognition result In the case of for " in allowing ", processing attribute turns into " cash species A and true certificate and complete certificate " identically with recognition result（In figure （1））.In contrast, recognition result is identical but character identification result for " allowing outer " in the case of, due to shown in Figure 17 Allow to be set as in the case that the bank note of cash species A is set as allowing outer process object bank note, to locate in outer treatment setting Reason attribute is set to " damage certificate ", so the processing attribute of the bank note turns into " cash species A and true certificate and damage certificate "（In figure（2））.
Additionally, for example, being " cash species B and true certificate and complete certificate ", character identification result in recognition result as shown in figure 18 It is " allowing outer ", and in the case where in allowing outer treatment setting being set as that processing attribute is set to " rejection certificate ", the bank note Processing attribute turn into " rejection certificate "（In figure（3））.
Additionally, for example, being " cash species C and true certificate and complete certificate ", character identification result in recognition result as shown in figure 18 It is " allowing outer ", and in the case where in allowing outer treatment setting being set as that processing attribute is set to " damage certificate ", the bank note Processing attribute turns into " cash species C and true certificate and damage certificate "（In figure（4））.
In the case of transfer destination in setting is processed outside the permission shown in Figure 17 turning into " device setting ", based in paper Setting in coin processing unit 1 and carry out the transmission of bank note.For example, being set as being stored on damage certificate the damage certificate storage part of regulation In the case of, although recognition result be " complete certificate " if but processing attribute be " damage certificate ", the bank note be sent to damage certificate storage part （In Figure 18（2））.In contrast, being set as being set to processing attribute " damage certificate " in processing setting outside the permission shown in Figure 17 In the case of transfer destination is set into " rejection portion " simultaneously, processing attribute turns on the basis of " damage certificate ", and the bank note is sent to " rejection portion " is rather than damage certificate storage part（In Figure 18（4））.
Even if in the case where " damage certificate " is set as in allowing outer treatment setting, the recognition result of identification part 2 is " damage certificate " Bank note be also processed as " damage certificate " identically with recognition result.But, set transfer destination during outer treatment is allowed Surely in the case of being set to " rejection portion ", although recognition result and processing attribute are all " damage certificates ", it is also possible to which the bank note is passed " rejection portion " is sent to rather than damage certificate storage part（In Figure 18（5））.
Thus, in bank note treatment device 1, by allow outer treatment setting, can according to based on recognition result The different processing attribute of currency note attribute and process bank note, or be sent to transmission mesh corresponding with currency note attribute or processing attribute The different transfer destination in ground.Thereby, it is possible to neatly tackle the utilization of user.
In the case where transfer destination to be set as rejection portion in allowing outer treatment setting, it is mixed in rejection portion The original rejection bank note of the bank note that can not be recognized by identification part 2 etc. and it is sent to rejection portion based on outer treatment setting is allowed Bank note.In bank note treatment device 1, due to this situation of user report, so being displayed in rejection portion in operating portion 3 is shown In the information of bank note that is mixed.
Figure 19 is the figure of the example for representing the picture shown in operating portion 3 is shown.In picture, such as Figure 19（a）It is shown, Show for represent rejection portion include the result that the character recognition based on number processes and as allowing outer process object paper The information of the bank note that coin is rejected.Additionally, whole bank note numbers in being displayed in rejection portion, the number of original rejection bank note, By the character recognition of number it is bad and as the number of the bank note for allowing outer process object bank note to be rejected.Additionally, showing in the lump Show the information of the ratio for representing each number.
If additionally, operation is in Figure 19（a）Picture bottom detailed ACK button, then show operating portion 3 in, as figure （b）It is shown, it is displayed in the banknote image of the bank note accumulated in rejection portion.In the picture, display bank note is distinguished by reason is rejected Image, can press the button while confirming all to reject the banknote image of bank note.User can show according in picture Banknote image in the cash species that obtains or number etc. information, select the bank note in rejection portion, carry out necessary treatment.
Then, the flow of the treatment in bank note treatment device 1 is illustrated.Figure 20 is to represent the bank note as shown in Fig. 1 ~ Fig. 3 The flow chart of the summary of the bill handling that processing unit 1 is carried out.First, if being inserted notes here in bank note treatment device 1, by passing Send control unit 10f to be sent to identification part 2, carry out the acquirement of banknote image and the knowledge of identification cash species, the true and false and complete damage Manage in other places（Step S1）.If bank note is identified, according to the number information 20a for being preserved in storage part 20 in advance, clearly in paper The position of the number on coin.
Then, character recognition treatment is carried out as 4 ~ Figure 10 of reference picture explanations（Step S2）.Specifically, by number figure As cut-out portion 10a cuts out number image from banknote image, further, cut from number image by character picture cut-out portion 10b Go out number everybody character picture.Then, the character recognition mould for being preserved in storage part 20 using the character picture and in advance Plate 20b, carries out the character recognition based on character recognition part 10c and processes.Determine to make character identification result by number determination section 10d To determine which in character, candidate characters, error character.
Then, recognition result is based on by processing attribute determination section 10e and judges whether bank note is true certificate（Step S3）.So Afterwards, in the case where bank note is true certificate（Step S3：It is）, it is determined that whether including into the character identification result of number It is error character digit（n）Count target position（Step S4）.Based on being preserved as processing attribute set information 20c in advance Set information in storage part 20, i.e., the concentration setting shown in Figure 15 or the detailed setting shown in Figure 17, carry out this and sentence It is fixed.Specifically, the cash species C in the detailed setting shown in concentration setting as shown in figure 15 or Figure 17 sets like that In the case of, the digit of miscount character.Additionally, being set as in error character digit the cash species D such as Figure 17（n） In the case of including ambiguous position and the both sides of position can not being recognized, judge whether to include in character identification result error character or At least one of ambiguous position of person.
Include turning into error character digit in character identification result（n）Count target position in the case of（Step S4： It is）, by processing attribute determination section 10e as error character digit（n）And be calculated as the number of the position of count target, and with mistake Character allows digit by mistake（N）It is compared（Step S5）.In addition, in the setting of Figure 15 or Figure 17, as certain bits such as Specify as shown in Figure 16 determine object position in the case of, only using determine object position as object mistake in computation character digit （N）.
In the case where error character digit allows digit beyond error character（Step S5：It is）, the bank note is judged as It is to allow outer process object bank note, is processed based on outer treatment setting is allowed（Step S6）.
In the case where the condition of step S3 ~ S5 is unsatisfactory for（Step S3 ~ S5：It is no）, judged by processing attribute determination section 10e Must recognize whether position is to determine character（Step S7）.Specifically, in the setting of Figure 15 or Figure 17, as certain bits Specify as shown in Figure 16 in the case of must recognizing position, whether the character identification result for judging that position must be recognized is determination Whether character, i.e., it is not ambiguous position or position can not be recognized.Then, it is not to determine character in the character identification result that must recognize position In the case of（Step S7：It is no）, it is judged to be to allow outer process object bank note, carry out based at the bank note for allowing outer treatment setting Reason（Step S6）.
Based on the treatment for allowing outer treatment setting（Step S6）In, processing attribute determination section 10e be based on such as Figure 15 or The processing attribute and transfer destination for setting and determining bank note are processed outside permission shown in Figure 17.Then, transmission control unit 10f exists In the case of " device setting " being have selected as allowing the transfer destination of outer treatment setting to set, the treatment category based on bank note Property and bank note is sent to corresponding transfer destination, in the situation of the transfer destination of the regulation for specifying " rejection portion " etc. Under, bank note is sent to the transfer destination specified.
On the other hand, not set as certain bits in the setting of Figure 15 or Figure 17 must recognize the situation of position Under, or set must recognize position as determine character in the case of（Step S7：It is）, the bank note be based on device set and located Reason.The recognition result of identification part 2 is namely be based on, bill handling as in the past is carried out.
In addition, if the step S3 ~ S5 shown in Figure 20 carries out same treatment, processing sequence is not limited to this.Additionally, Treatment on step S7, for example, can also be processed in character recognition（Step S2）And then carry out that the judgement of position must be recognized afterwards Treatment（Step S7）, and it is judged to be in the case of allowing outer process object bank note, to omit at the judgement of step S3 ~ S5 herein The mode of reason.
Industrial applicability
As described above, the present invention is the number that paper is recognized according to character recognition grade corresponding with the utilization of user, And while leaving information that character identification result is obtained as needed, in the case of user is desired, known according to character Other result and carry out different bill handlings and useful technology.
