Description

[0001]
[Industrial applications]
The present invention relates to a barcode reader for decoding a captured image using a scanner such as a barcode reader. Regarding the optical sensor for image capture, a point sensor captures a point image, a line sensor captures a line segment image, and a band sensor captures a band image obtained by capturing in the scanning direction with a predetermined width. A sensor that captures a surface image of a certain size is called a surface sensor. From actual market products, a pen scanner is used as a point sensor, a one-dimensional CCD sensor is used as a line sensor, a one-dimensional CCD right-angle sensor that scans in a direction perpendicular to a line of a one-dimensional CCD sensor is used as a band sensor, and a two-dimensional is used as a surface sensor. CCD sensors are currently the mainstream.
[0002]
[Prior art]
As a conventional technique, data to be read is represented by a vertical bar horizontal bar code (a standardized bar code is almost any type), printed, and the vertical bar horizontal bar code is formed. Has been captured with a one-touch barcode reader, and the captured image has been decoded and converted to decoded value data. This method was convenient and convenient because data can be read with one touch. Bar codes have been standardized, and this standardization has caused a further general spread, and has been commonly used for a long time, has been convenient, and has been used in many fields.
[0003]
However, the barcode needs to be printed accurately. For this reason, a handwritten barcode could not be considered. Handwritten barcodes have individual differences in accuracy and are not practical.
[0004]
At present, the process flow of reading an accurately printed barcode with a barcode reader has become established and is now used without any inconvenience. Rather than the conventional fixed use system like this, anyone can write barcodes by hand and read it in their own way, build a self-style barcode system using self-style barcodes, If a new PD system is constructed to replace the POS system using the self-flow barcode system, a temporary and flexible utilization system can be realized. Expected to be easier to use and more convenient, so it can be used throughout office work and reduce the labor required for work It is.
[0005]
From the default sticky use that utilizes standardized barcodes to a flexible human / machine interface that allows you to easily attach some patterns, not necessarily bars, and read them as corresponding information. If this path is opened, data entry work will be easier at a stroke. On the spot, hand-written, self-made, simple, self-made barcodes are created, and instantaneous data entry using this is realized, so that the so-called “oneself, oneself, oneself” barcode system is realized. The advent marks the beginning of a new era for the OA system. You need a car, but you also need a bicycle.
[0006]
[Problems to be solved by the invention]
The standardized barcode has the advantage that the number of distinctions, which is the number that can handle data, is large (high reading accuracy). However, the data input using the barcode is actually the number of data to be handled. The calculation of the number of distinctions (step 1), the creation of a barcode (step 2), and the construction of a barcode system for registering the decode value corresponding to each barcode (step 3) must be performed first. Since application development of an application system such as POS based on a bar code system is required (step 4), only highly standardized ones are currently being used in the public, instead of this. The concept of handwriting had no room for entry into the barcode world due to the environment where redundancy was not allowed, but it escaped from the idea of the ruler and reduced redundancy. Are those that attempt to introduce a fuzzy ideology in the world of the bar code.
[0007]
Even if you are not an information processing person, just by setting a few parameters, the bar code can be flowed in your own way and the reading method is ambiguous, just as if you were a general office worker. With a few settings on the fly, and save these settings, automatically read the settings according to the data, handle the pattern of a little sign, and decode the desired code. Is to automate steps 1 to 4 almost completely. Certainly, it is unavoidable that the rule-like ruler limit is inevitable when targeting an unspecified number of users, but when targeting private limited users and handling extremely few types of data, It was rather unnecessary to restrict the scoop ruler, and focused on the possibility of a method of realizing data entry in a "quite appropriate manner". For example, knives are an effective tool for cutting radishes, but razors are useless (in cutting).
[0008]
For example, it is difficult to count the location and the number of 0.1 mm-sized objects within 1 cm unless a ladle ruler is used. However, when there are at most several 1 mm-sized objects within 1 cm (from the middle point) It is possible to count the location and the number of places (before or after, somewhere at the beginning, middle, or end of the three sections) without using a scissor ruler. In addition, it is my own job to count, and based on the idea that if I write with some care (beginning, middle, ending) to avoid reading errors, myself will be easier. , A PD system has been devised.
[0009]
In general, standard barcodes are standardized, and they are bar-column horizontal barcodes (representation of barcodes usually affixed to products), which are scanned by a pen scanner in the horizontal direction. With this, or with a normal barcode reader, one reading unit is read by one touch (optically, the image is scanned by scanning (scanning) in the horizontal direction). It is intended to fundamentally reconsider this standard barcode and its application system such as POS.
[0010]
More specifically, an instantaneous barcode is created privately (for oneself), a correspondence between the instantaneous barcode and data is created, and thereafter, the instantaneous barcode is used to express data in a handwritten manner. A pattern code (PD) method of inputting with a bar code is adopted. If the user understands the PD method, follows the handwriting rules, and writes and uses the instant barcode, there is no misreading. It is intended to realize the convenience of data input by flexibly creating “oneself, oneself, for oneself” barcodes as needed, and the background to this, steps 1 to 4 Is almost automated, the user can input and read data using the barcode simply by setting a small parameter value and registering the data to be handled.
[0011]
Furthermore, if this PD system is spread to the group, it becomes a formalized local standard within the group, and a PD information processing system that adopts the PD system without any inconvenience can be constructed.
[0012]
For example, if one teacher personally uses a simple handwritten barcode to input attendance / grading data smoothly, and other teachers use it as well, the teachers can use it and spread it out. A local PD utilization group utilizing standard barcodes will be completed.
[0013]
Further, by adopting the PD method, it is possible to eliminate the conventional idea of reading one row per bar code and one bar code, and realize one bar reading and one bar code reading.
[0014]
The own bar means that a bar code need not be a bar code in which a plurality of vertical bars are arranged in a horizontal direction. The point is that the code only needs to be read by scanning using a pen scanner, bar code reader, flat scanner, etc., so if it is possible to realize identification accuracy that suits its own application, handwriting / printing It is not limited to a bar, and it may be a horizontal row of columns or a vertical row of diagonal bars. Further, since it is sufficient that a scanned image can be read, it does not necessarily have to be a bar, but may be a pattern or a dot.
[0015]
The point is that the pattern may be read by scanning. In that sense, it is more accurate to use a self-pattern arrangement instead of a self-stick arrangement. However, since it is a specification of my own style, there is a premise that "scanning to write and read correctly is exactly oneself.""Only ourselves, our own group, and the closed area", "Because it is a specification of our own style, it is ourselves that it is ourselves that we understand the specification well, follow it, write it correctly, and read it correctly. (Aside from those who want to carry their own hardships).
[0016]
As described above, the barcode of the self-owned bar is exactly the barcode of the self-style, and is a barcode created and used by the user in consideration of his / her own convenience. Each of the above steps 1 to 4 must be created by the user, from the specifications described above to the application system. However, general office workers cannot be forced to do programming work. The problem is to provide a PD system automation function that automates from PD design to application system construction.
[0017]
If you use the PD system automation function to select the necessary items or set the PD setting information, which is the setting, as if you are always doing office work, a PD system is automatically created, and based on the PD system, Register the data corresponding to each PD. Next, there is a need to prepare a PD decoding function for decoding the expression or the input PD based on the PD setting information and passing the decoding result as a decoding value to the application.
[0018]
The PD decoding function is to perform image processing on an image captured by scanning, but in this case, it is extremely simple. As described above, it is easy to grasp the location and the number of the black dot groups which are handwritten / printed in the space of 5 mm to 10 mm (hereinafter, cell section). In addition, it is easy to determine whether an effective black point sequence exists before or after the intermediate point or in each of the three sections of the cell section. However, actually, even in the case of handwriting / printing, black spots due to dust may occur, so some correction processing is required.
[0019]
As this correction processing,
{Circle around (1)} The condition of the effective point is determined only when the existence of the black point is considered to form a continuous group to some extent. (If the isolated point is excluded from the category of the effective point, it becomes extremely isolated. Is interpreted as being ignored)
{Circle around (2)} PD should be entered in the cell (where the PD is entered in the actual frame created by the ruled line). A bar, which is a component of the PD, is written in the element frame in which the cell is further virtually divided into a plurality. The vicinity of the cell or the element frame is a predetermined width, and even if a part of the bar is present, it is erased and left blank.
{Circle around (3)} Assume that the effective points obtained when scanning the determined cell area are those of the PD.
And so on.
That is, the PD is written in the cell, and each bar is written in the element box. That is, when the number of element boxes existing in the cell is 2, bars are written in the front element box and the rear element box, respectively. Since the element frame lines virtually existing in the cell are invisible, if the number of element frames is 2, it is roughly from the middle to the front or back, or if the number of element frames is 3, the cell is roughly 3 element frames. Each bar must be strictly adhered to the basic rule of writing each bar so that it can be determined whether or not it exists in which category, that is, the element frame, such as around the center, around the back, etc. . Until now, it has not been clarified, but if you describe patterns and bars here, barcodes are mentioned as an example of patterns, and the barcode is a bar, so the barcode is a group of bars Therefore, the entire barcode is called a barcode when it is recognized as an object to be coded, and the barcode itself is composed of bars and is a collection of bars, In some cases, a bar code may be abbreviated to a bar.
[0020]
Next, the batch reading of the multi-PD is a method of scanning in the vertical direction when the own bar is in the horizontal column. For example, if the number of data is 50, 50 in the vertical direction. A method of reading columns of 50 horizontal bars PD of data at once without reading PDs at once. Here, when vertically reading a column of 50 horizontal bars PD of data, the manual scanning operation is performed in the vertical direction at once, but a large number of PDs are processed in each PD unit, that is, in processing. In this case, since the decoding operation is performed 50 times, the collective reading operation is called one scan or one scan. In one reading of 50 PDs, 50 readings in 50 cells arranged in a line are performed. That is, the PD group is read by one scan.
[0021]
In addition, the present invention breaks away from the conventional reading style in which a barcode reader is held by hand and is applied to a barcode, and a mouse which is almost equipped in a computer is provided with a function of reading a barcode. After that, you do not need to hold the barcode reader by hand, and according to the barcode reading method provided by the mouse, if you use a commercially available barcode reader that uses a line sensor such as CCD, hold the mouse on the barcode surface. If a pen scanner adopts a point sensor such as a photoreflector instead of one touch, a mouse is placed on the barcode surface, and reading is performed by one scan by dragging the mouse. To scan the barcode surface, place a mark on the mouse at a predetermined location, for example, on the left, right, or top, and use it to determine the location of the barcode, or clear the mouse at a predetermined location or all. Just fine.
[0022]
Also, with the light-emitting and receiving optical mouse that has been on the market at present, it is possible to compare the time-dependent changes of the fine surface that cannot be visually distinguished with the optical sensor opening but can be distinguished with a microscope, and the mouse movement direction etc. Mouse information is determined by the mouse information determination function. Separately, a slit for a bar code reader function, for example, a slit of a CCD line sensor or a pen scanner port is provided near the optical sensor port, and the mouse function and the bar code reader function are switched by a mouse / scanner switching unit. You may make it selectable.
[0023]
Further, the captured image captured by the optical sensor port of the optical mouse is used for the mouse information indexing function and the bar code reader function of the pen scanner port and the like. The switching may be performed by the scanner switching unit. Specifically, it is sufficient to switch between using the captured image obtained from the optical sensor port for mouse information indexing and for barcode decoding.
[0024]
Importantly, the captured image of the microscopic region obtained from the optical sensor opening of the optical mouse is stored in pairs with the position information obtained by processing the mouse information by the mouse information indexing function, The micro-areas are linked by the positional information, and the scanned image is finished, and the scanned image is assumed to be scanned by a pen scanner.
[0025]
The following is a brief description, but there is a magnification difference of at least several tens between visual accuracy and microscope accuracy in terms of improvement in processing speed. It may be several 0.1 mm for visual recognition, and several 0.001 mm for movement detection on a clean office desk surface using a microscope. For this reason, from the viewpoint of improving the processing speed, the number of data to be processed is reduced by thinning out the images taken from all the optical sensor ports at a specific sampling time interval, and the magnification conversion from the software or hardware side is performed. Adjustments can be considered. Thus, the microscopic vast surface is reduced and returned by the magnification conversion, and the visual micro surface such as a normal PD is observed, and the connection of the micro surface obtained by thinning out by appropriate sampling is performed. To form an image of a scan line captured by a conventional pen scanner.
[0026]
Note that the reading is not limited to the actual reading in which the PD on the actual paper that is the actual paper is read, and the virtual reading in which the PD on the virtual paper that is read by an image scanner or the like and is a captured image already existing in the computer is read. Conceivable.
[0027]
A real-time tracing operation in which an object to be read having a PD is once captured by an image scanner or the like, and then the captured image captured by a computer is traced on a PD scanning line by a pen scanner or the like on a real paper. The same operation as described above is performed by a virtual slewing operation of performing a soft scan on a predetermined scan line on the captured image. The operation after the virtual sledding operation may be the same as the operation after the real sledding operation.
[0028]
[Means for Solving the Problems]
In order to solve the above-described problem, the gist of the present invention is to make it possible to easily create a PD, which is a handwritten pattern code that can be easily described on paper, and to register a decode value of the PD easily. A plurality of registered PD setting information is managed by an identification ID such as a page number, and automatic setting information can be called in accordance with the identification ID to be read. The PD setting information is decoded and decoded. By preparing a PD system such as a POS system by passing a decoded value to information processing, a system is prepared. Specifically, in a cell of a form sheet with ruled lines, PDs automatically created based on PD setting information and data registered corresponding to each PD are referred to, and handwriting / Only by writing the PD in the printing, the image of the PD is captured by scanning with a pen scanner or the like, and the decoding is performed in reverse according to the PD setting information. If there is an identification ID that is the identification information for distinguishing the setting information on the form sheet, specifically, if there is a page ID, the corresponding setting information is searched for in the setting information management using this, and based on the setting information, Decrypt.
[0029]
It is assumed that all PDs are written in cells surrounded by a ruled line having an appropriate thickness that can be read by a pen scanner. This is because, when scanning with the pen scanner, there is always a ruled line portion before and after, and a configuration in which the start / end of PD reading is recognized based on the ruled line portion can reduce the reading error rate.
[0030]
In simple cases, this ruled line may not be necessary. For example, when only reading a PD at a fixed location, that is, when reading a PD with fixed PD setting information, a reading synchronization PD is provided at the beginning or end of scanning, and a series of This is because it is possible to easily decode a series of a plurality of PDs from the position of the bar which is a component of the plurality of PDs. The read synchronization PD is usually printed on paper from the beginning.
[0031]
Regarding the PD setting information, a sheet on which the PD is written is set as a page, and the page is scanned by tracing the page with a pen scanner. When the page requires a plurality of scans, a scan for identifying each scan is required. A data scanning number as identification information is also added. The scanning direction may be a vertical direction from top to bottom or a horizontal direction from left to right. The scanning direction may be oblique. In short, it is sufficient that the image of a series of image lines of PDs is captured in one scan by quickly tracing with a pen scanner. A plurality of cells exist in one scan, and each cell contains one PD. If necessary, cells for scanning start / end symbols for scanning start / end may be provided, and a cell number is associated with each cell from the beginning to the end between scanning start and end symbols. Each cell has a limit on the number of data that can be registered. This limit indicates how much data can be expressed in each cell, and is the same as the frame setting number indicating the number of cells.
[0032]
Regarding the reading synchronization PD, the reading synchronization PD provided at the beginning and / or end of scanning has data scan numbers of a plurality of scanning locations. By doing so, it is possible to scan a desired portion and scan only the desired portion without scanning the whole, but a separate cell for the scan number may be separately provided. Specifically, a scan start / end symbol is written in the cell of the read synchronization PD of data (usually, it is printed on the page from the beginning to improve the accuracy of the read synchronization). Further, it is more convenient that the scanning start / end symbols also serve as scanning numbers. When performing multiple scans on one page, consecutive scan numbers are assigned from top to bottom and from right to left. Can be identified by number.
[0033]
The PD setting information includes a PD definition unit for setting a scanning frame of one scan determined by a page ID, a scanning number, a scanning direction, a cell number, and a frame setting number, and is automatically determined by the PD definition unit. It comprises a data registration unit for the user to register for each PD in each PD list. When a setting value is input to the frame setting number, a PD / data correspondence table of a PD list corresponding to the frame setting number is automatically displayed, and a PD-converted image displayed on the PD / data correspondence table is displayed. The user registers the registration data in the corresponding blank. A method of creating a series of PDs in the PD list is as follows: (1) A method of automatically creating an external character PD using an external character registration unit and automatically displaying the same in a PD / data correspondence table; (2) PD / data Both the place where the PD list of the correspondence table is displayed and the place where the data is registered are blank, and each PD can be freely and freely set there manually (drawing method using the mouse cursor or the direction key) (however, A method of registering / editing a pattern PD that can be easily edited later. (3) Create a large number of PDs in advance, such as creating icons, using image processing such as a paint brush. In addition, a method of automatically displaying in the PD / data correspondence table, (4) a vertical bar or a horizontal bar is prepared by external character registration / manual / drawing, etc. A series of PDs automatically Create, method and the like can be considered to be automatically displayed on the PD / data correspondence table. As an application of the PD, a signature such as a signature of the user is created by the external character registration / manual / drawing to be a signature PD. Personal information can also be captured.
[0034]
Regarding the cell number setting, when the cell number is set to, for example, “1, 50”, it indicates that “from 1 cell to 50 cells” is repeated, and “(1, 3)” In this case, the item of the number of frames is not displayed, and the item of data is displayed. In this case, a plurality of cells are collectively handled as a bit string, and if each bit is set, the corresponding data is decoded from the data string. For example, if the cell number setting is “(1, 4)” and the data string is “text, engineering, sutra, modulus”, if the bit string is “0010”, “sutra” is decoded.
[0035]
With the use of PDs, the use of PDs will be expanded, and if, for example, the conversion of attendance sheets to PDs succeeds, the conversion of grade sheets to PDs will be considered. In the evaluation of the grade table, raw scores such as 75 and 63 are not used, and usually excellent, good, acceptable, unacceptable, or A, B, C, D, Z, etc. are used. In order to distinguish between the attendance book and the grade table, the concept of a page is introduced, and an identification ID is assigned to each page. That is, a page exists for each PD setting information, and does not indicate a page simply indicating the number of sheets of a book. In the PD system, a certain page is specified by scanning a page ID portion from a large number of pages with a pen scanner, and thereafter, a data scanning portion is specified by a data scanning number, and the data is scanned on this scanning line. The PD in each cell which is separated before and after by the ruled line after the start symbol is decoded. The page ID is obtained in the first scan, the data scan number which is the content of the scan start symbol of the cell of the PD for data read synchronization, and each cell, and then the scan end symbol are obtained in the next scan. become.
[0036]
Further simple methods are possible according to the usage of the PD system. If only one page is used, no page ID is required. If only one scan is performed on this page, no scan number is required. If each cell is surrounded by ruled lines, no start / end symbol is required. In addition, when the user writes his / her own PD on a character in which the start symbol is printed with an accurate width from the beginning, the ruled line for the cell is not required. The scanning speed of the pen scanner is determined from the width of the accurate start symbol in one scan, and the subsequent PD may be read on the assumption that the speed hardly changes thereafter.
[0037]
Considering the number of registered data, in the above example, extremely small number such as 2 (existing, no), 5 (A, B, C, D, Z), 4 (excellent, good, acceptable, unacceptable) The utilization of PD system is effective in the range that deals with.
[0038]
To put it another way, you can arrange clay balls by hand, and you know the place where the dumplings are placed to a certain extent. Therefore, the existence pattern of the clay ball can be easily determined. It is even easier to determine the presence or absence of dumplings in the frame having a frame line that determines the cell range. In this case, it is caused by the non-uniform speed in one scan due to camera shake in the scan of the pen scanner. Decoding errors are not a problem.
[0039]
By creating a database of PD setting data consisting of PD setting information with the page ID at the head in the PD system, the current PD setting data can be found from a large number of past PD setting data with only one scan of the page ID To According to each usage pattern of each user, the PD setting data is accumulated by the number thereof, and one scan of the page ID of the user determines which PD setting data corresponds to the usage pattern. If there is more than one candidate, the candidates are listed on the monitor screen, and when the user specifies one of them, the image of the selected page is displayed, which can be visually checked and selected. The tedious input work that is often done in office work is simplified.
[0040]
When a bar code reader is provided with a standard conversion plate provided with a transparent sheath, a bar code is dropped at a plurality of predetermined locations, and a transparent sheath is provided. When the barcode reader is shifted and removed from the barcode reading port, the barcode reader returns to the original barcode reader for reading the conventional barcode in the standard mode. The seesle port may be provided at a plurality of locations as needed.
[0041]
The barcode reader decoder is modified to have both a standard barcode reader function and a PD reader function, and the standard / PD switch is used to select either one. In this case, a standard / PD switch is required. Alternatively, when the read image is out of the standard, a warning is issued, and in that case, the mode may be automatically switched to the PD mode for reading as a PD. In this case, the standard / PD switching switch becomes unnecessary and the standard conversion plate becomes unnecessary, but the decoder part needs to be remodeled.
[0042]
In the case of reading with a pen scanner, when using only PD without ruled lines, there is variation in the scanning speed due to individual differences and the read error rate is high, so the synchronization mark is printed alongside the PD. The pen scanner has two sensor functions and is used for the PD and the synchronization mark. By reading the PD and the synchronization mark in parallel, reading independent of the scanning speed is realized. it can.
[0043]
Next, a bar code reader function may be added to the mouse, and a mouse / bar code reader switch may be used to switch between the mouse and the bar code reader. As the barcode reader function, a one-touch reading method using a CCD line sensor and a one-scan reading method on a barcode using a pen scanner can be considered.
[0044]
There is also an optical mouse in which a barcode reader function is added, and a mouse / scanner switch is used to switch between the mouse and the barcode reader. As a barcode reader function, a one-scan read method on a barcode using a pen scanner can be considered.
[0045]
The pen scanner may be omitted, and the read image of the optical sensor opening with the optical mouse may be used for both the mouse moving distance determining function and the barcode reader function.
[0046]
In a soft scan, a portion corresponding to a scan line is cut out with a certain width by software so that a pen scanner or the like traces a PD portion, that is, image information on a line corresponding to a scan line on a read image. And take this as the capture image.
[0047]
In the PD system, a handwriting is read by a pen scanner or the like and taken into the computer, but the PD pattern itself is created as an external character and registered as a font, and the PD is handled in a manner that is mixed with the handling of ordinary characters. It is possible to be. In this case, as a method of creating a PD, (1) a method of manually creating a pattern that resembles the PD by a normal external character registration procedure by the external character registration can be considered. A method of reading the entire pattern with an image scanner and converting it into an external character, and (3) a method of converting an existing character, for example, the character "1", into an image in the form of a bitmap or the like by computer processing to convert the character to an external character can be considered. .
[0048]
[Action]
When the PD definition information of the PD system sets the PD setting information according to the usage pattern, a PD list is automatically created, and the data registering section stores a PD / data correspondence table of each PD and its corresponding decode value. Appears, and data corresponding to each PD in the correspondence table is registered. Next, the PD decoding unit of the PD system scans a plurality of ruled line portions with a pen scanner from top to bottom and from left to right on the page of the single table format paper, and takes in the image data of each cell, Will be decrypted. More specifically, the page ID is decoded from the image data of the first ruled line portion, and the usage pattern database function searches for PD setting information, which is the corresponding PD setting data, using this page ID as a key, and then scans the scanning line. , A scan location on the page is specified, a cell group including a plurality of cells existing on the scan line is determined, and cells corresponding to cell numbers are decoded in order from the top of the cell group.
[0049]
As a simple usage mode of the PD system, there is one ruled line portion in the page regardless of whether it is in the vertical direction or the horizontal direction. The PD setting data corresponding to the previous use status is valid as a default value, and the image data is taken in and decoded in the immediately preceding method by scanning the ruled line portion once with the pen scanner.
[0050]
A mouse is provided with a barcode reader function, and the mouse function and the barcode reader function are switched by the switching means, and used as a mouse or as a barcode reader.
In particular, with an optical mouse, a barcode reader function can be added by software without changing the hardware.
[0051]
In the software scan, the same information as the information captured by scanning with the pen scanner can be obtained by capturing the location corresponding to the scanning line on the virtual paper by software, like tracing the PD location with a pen scanner or the like.
[0052]
【Example】
Hereinafter, the present embodiment of the present invention will be described with reference to the drawings.
1A and 1B are diagrams of the first embodiment in which the PD system of the first current embodiment is used for reading the attendance book 10, respectively. FIG. 1A shows a PD definition section 1 displayed when a PD definition is selected from a menu of the PD system. Each item “Page ID 7” is 7, “Scan number” is 1, and “Scan direction” is vertical. , When the cell number is set to 1, 50 and the “frame setting number” is set to 4, the data registration unit 2 corresponding to these set values is displayed, It indicates that the PD setting information is completed by registering the data which is the decode value corresponding to the PD, and registering it as missing, early, or late. That is, the PD setting information is completed by setting the PD setting information in the PD definition unit 1 and registering the data of the decoded value in the data registration unit 2.
[0053]
The data registration unit 2 automatically displays, according to the scanning direction, a PD list including a horizontal bar PD in the vertical direction, a vertical bar PD in the horizontal direction, and a number of PDs according to the number of frames set. Then, corresponding data is registered under each PD. The reason why the item “cell number” is set to “1, 50” is to set that cells exist from 1 to 50. For example, when “1, 4, 7, 7, 50” is set, cell numbers 1 to 4 and 7 to 50 are designated. As will be described later, when “(1, 4)” is set in the item “cell number”, it is treated as a bit string. That is, there are four bits, and a data string indicating which data is to be a decoded value when the bit is set is registered. In this case, the item “number of frame settings” is not displayed.
[0054]
FIG. 1B shows a case where the present invention is applied to the attendance book 10, which corresponds to a case where there is a page ruled portion 3 at the beginning and the next data ruled portion 4 is one. When there are a plurality of data ruled line portions 4 as in the example, this operation is repeated by that amount, and PD setting information is created by that number. Naturally, since a plurality of data ruled lines 4 exist on the same page, it is necessary to set the same information in the page ID 7 in the PD setting.
[0055]
FIG. 1 (b) shows the attendance table 10 in which attendance has been obtained by filling in the attendance entry column of the data ruled line section 4 with the PD given in the PD / data correspondence table by using a pen scanner. And reading a series of PDs. The decoding result inside the machine is disclosed on the right side for reference.
[0056]
In this attendance book 10, there is a case where there is a page ruled line section 3 at the beginning and there is only one next data ruled line section 4. If there are a plurality of data ruled line portions 4, FIG. 1A is repeated by that amount, and PD information is created by that number. However, since the information is PD information on the same page, the same value is entered in the item “page ID” in the PD setting table.
[0057]
FIG. 2 relates to a scanning mistake, but such a mistake may occur, but since the user himself writes and manually scans with a pen scanner, it is assumed that the PD system is operated at his / her own risk. Therefore, it suffices to keep scanning only while avoiding such a situation. Otherwise, you only lose.
[0058]
FIGS. 3A and 3B are examples in which the PD system of the second embodiment is used for reading an attendance card. Since the setting value in the item “scanning direction” is “horizontal”, the PD is a vertical bar, and the first current embodiment uses the cell number designation method. The setting method in the "address" is "1,50". In this embodiment, the setting method in the item "cell address" is "(1,4)" in the example of the bit string number designation method. is there.
[0059]
In the PD setting table, in the bit string number designation method, an item “data” appears instead of the item “frame setting number”, and a decode value when the corresponding bit is set in order from the top is registered here.
[0060]
In PD decoding, a series of corresponding PD setting information sequences are obtained from the PD setting information database using the page ID 7 obtained by scanning the page ruled line section 3 as a key. In this case, since there are three data ruled lines 4, the PD setting information sequence is composed of three pieces of PD setting information corresponding to each of the three scans. Here, the head of each ruled line portion is provided with a cell for a scan number (here, binary numbers 01, 10, 11 represent 1, 2, and 3 respectively). It can be specified whether the ruled line portion has been scanned. Thus, any ruled line portion can be scanned. Since the cell for the scan number is an entry of the PD system operator, it is usually already printed or previously written in the PD. In the item of the scan number, "2, 3" is described in a simplified notation when the PD setting information is the same, and may be described in three lines for each scan number. Also, when a series of PD setting information is entered, a line is automatically added and appears to prompt the user to input new PD setting information, or PD setting information can be added / deleted. This may allow registration of a necessary number of pieces of PD setting information. In the PD setting information list on which a plurality of pieces of PD setting information are displayed, the selected PD setting information is changed from the surroundings by changing the background color to indicate that the selected mode is the selection mode. . Then, every time the PD setting information is selected, a PD / data correspondence table corresponding to the PD setting information is displayed.
[0061]
In the scan b-line 15, since the PD is written in the third bit, the items "data" through "PD" in the PD setting table are decoded. In the scan c line 16, "2" is similarly decoded because the PD is written in the second bit, and in the next scan d line 17, the PD is written in the seventh bit. As a result, “7” is decoded, and “27” is passed to the application side. As a result, the attendance card 20 is for the student with the attendance number “27” of “Faculty of Economics”.
[0062]
FIG. 4 shows a process in which a captured image obtained by scanning a ruled line portion with a scanner reaches a read bit string 26. The read bit string 26 includes a solid frame and an effective point group (1) of a PD bar. ) And blank areas (columns consisting of only zeros). Effective point groups include those with real frame lines and those with PD bars. The PD is determined by the number of PD bars and their positions during the position synchronization, and the corresponding data in the data registration unit in the PD setting is decoded.
[0063]
FIG. 5 shows an embodiment in which the PD reading means can be read by simply attaching an adapter component without modifying the decoding part of the existing standard barcode reader 30.
[0064]
Most of the existing barcode readers 30 have a built-in decoding function, and cannot read nonstandard barcodes even if the computer has a built-in decoding function. For this reason, in order to read non-standard barcodes such as PD, it is necessary to modify and modify the decoding part, but it is not easy to modify the decoding part. No product offers a means to read non-standard barcodes.
[0065]
Here, a standard conversion method has been devised as a non-standard bar code reading means, in which a non-standard bar code is read as a standard bar code. In this standard conversion method, one part of the standard barcode is deleted at a plurality of places as necessary, and a standard conversion plate 33 is provided in which the part is made transparent. That is, the sheath port 34 is provided at a desired location so that a plurality of locations of the standard barcode can be seen through the drop. The number and location of the see-through ports 34 are one at the center in this embodiment, depending on the application. When the number of frames is set to 2, one is provided, and if the number of frames is set to 4, two slits are provided so that each PD can be seen through. The standard conversion plate 33 is guarded left and right by the standard plate guide 32 and is slidable up and down. When reading a standard bar code, the bar code reading port 31 is shifted downward to release the bar code reading port 31, and when reading a non-standard bar code, the standard conversion plate 33 is slid up to close the bar code reading port 31. In this way, the barcode reader 30 answers one of two answers depending on whether the sheath port 34 is black or not. This answer is used to determine 1-bit information such as “true, false”, “a, b”.
[0066]
In the actual reading method, the PD is read by applying the portion of each sheath port 34 to each PD. Even if the handwritten PD is slightly displaced or has a variation in size, since the sheath port is transparent and elongated slit-shaped, it is read as a standard barcode from the barcode reader 30 side. Conversely, an image of a standard barcode is determined from the read data, and the PD is decoded based on whether or not a barcode bar is standing at the position where the PD exists.
[0067]
PD is a type of non-standard barcode. In the PD reading mode, a specific number of sheath holes are traversed from the barcode reading port 31 so as to trace a column of PDs of a horizontal bar from top to bottom with a pen scanner. By taking in an image from the provided barcode reading port 31, that is, by scanning once, it can be determined that scanning has been performed a plurality of times from a plurality of sheathing ports.
[0068]
FIG. 6 shows an example in which a standard / PD switching switch is provided in order to decode both the standard barcode and the PD by modifying the software decoder without using the standard conversion board 33. As for the standard, since the standard barcode and the PD can be easily distinguished from the captured image, an automatic standard / PD switching function for automatically reading the standard barcode and the PD and automatically switching to a reading mode according to the standard barcode and the PD is provided. This eliminates the need for a standard / PD switch.
[0069]
FIG. 7 shows an example in which a barcode reading port 31 is provided at the bottom of the mouse 50. A mouse / reading switch 53 is provided for switching the function of the mouse 50 and barcode reading. Since the mouse 50 is supported on the four supporting portions 52 and used on a desk, the barcode reading port 31 is provided at the bottom of the mouse 50 so that a barcode or a PD can be easily read on the desk. There is a merit that the movement synchronization at the time of reading an image (since it is difficult to keep the scanning speed of the pen scanner constant, a means for knowing how much movement has been required) can be realized without a separate provision. This is because the movement synchronization may be based on a method using the rotation of a mouse ball. Although described with reference to FIG. 8, movement detection image information of the optical sensor port 61 of the optical mouse 60 may be used. Movement synchronization is also used when reading an image with a hand scanner, and utilizes the rotation of rotating parts on both sides when tracing an image with the hand scanner. Standard barcodes, PDs, etc. can be distinguished from the image, so the standard barcode, then PD, if not, the image is automatically interpreted as other, and the processing for the captured image is followed. Just do it. Furthermore, since the PD system can determine either the decoded value of the standard barcode or the decoded value of the PD based on the captured image, a standard / PD switching switch for distinguishing the standard barcode and the PD is necessarily provided. No need.
[0070]
FIG. 8 shows an embodiment in which a pen scanner port 56 is provided at the bottom of the mouse 50 instead of the barcode reading port 31.
[0071]
FIG. 9 shows the present embodiment in which a pen scanner port 56 is provided in addition to the optical sensor port 61 of the optical mouse 60. The output signal is switched by a mouse / scanner switch 62.
[0072]
In FIG. 10, the sensor port 61 and the pen scanner port 56 are separately provided in FIG. 9, but the captured image (mouse image) from the optical sensor port 61 for the optical mouse 60 is so small that it cannot be visually observed. Level, and the captured image (pen scanner image) from the pen scanner port 56 is a visual level. Therefore, mouse / scanner mode switching is performed by the mouse / scanner switching switch 62, and the mouse image is changed to the pen scanner image. In the mouse mode, a mouse operation signal is output, and in the scanner mode, the pen-scanned image whose magnification has been converted is output. The magnification conversion is preferably provided on the PD system side, not on the mouse itself.
[0073]
The magnification conversion method is based on the original function of the optical mouse, while obtaining mouse movement information from a captured image at the microscope level, and simultaneously transferring the mouse movement information to the computer body once in accordance with the movement. A small image is paired with the small image at an appropriate sampling interval, and the computer is connected to the small image to form a thick line, and a reduction operation to reduce the line to a visual level.
[0074]
If the mouse image, which is a captured image at the microscope level of the optical mouse, is not practical for obtaining the pen scanner image with the magnification conversion function, the capturing area of the mouse image is slightly increased from the beginning. The pen scanner image may be improved so that it can be put to practical use by employing an optical mouse having the above-described optical system.
[0075]
For virtual reading, which is reading of PDs on virtual paper existing in a computer, PD recognition by image recognition processing is conceivable. However, since it is not necessary to read all PDs, that is, PD recognition by ambiguous reading is possible. In order to speed up the recognition process, it is preferable to take in only the necessary part by the virtual tracing work that cuts the image in the scanning direction, and then read the PD by the same processing as the actual scan. Good.
[0076]
Regarding the PD reading device, a plurality of slidable holders are provided on a rod that passes the reading portion of a conventional flatbed image scanner having a paper feeding function at right angles to the paper feeding direction, and a pen scanner is attached here. Thus, a PD reader capable of continuously reading PD paper can be easily realized. As described below, the PD recognition processing time for the captured image by the pen scanner is as follows: image capture of the entire paper by the flatbed type image scanner, then cut out to the necessary part where PD exists, position adjustment, pattern matching Considering the need for various time-consuming processes, for example, the PD reading device contributes to speeding up data input because it requires much less time.
[0077]
It should be noted that the PD system originally supports data types, that is, a small number of data types, and only supports short character strings such as {｛, ×, 1, 2, 3, 4}. The registration data registered in correspondence with each PD may be a character string of an arbitrary length, without being devised as described above.
[0078]
Next, as another application example, the use of the PD system in the process of writing by a word processor will be described. First, the PD system is activated, and the work ID of each work is set in the PD definition section 1 of the PD setting table. Input in the ID item, leave the scan number, scan direction, and cell number blank, enter 100 as the frame set number, and once terminate the PD system. Then, if you feel that it is a frequently used character string in the process of writing on the screen of the word processor, select the frequently used character string and click the "PD registration" icon registered in the tool menu of the word processor. Then, the program of the PD system starts, and the screens of the PD definition unit 1 and the data registration unit 2 appear. However, since the work is fixed, the PD registration unit 1 is not touched, and the data registration unit 2 does not. By clicking and selecting a desired registered PD in the PD list, the frequently appearing character string selected on the word processor is registered as a PD. In other words, on the word processor, the same operation as selecting the frequently-appearing character string and copying / pasting it to the clipboard / data portion is performed so that the “PD registration” operation is performed.
[0079]
Then, in addition to the “PD registration” icon, a “PD reading” icon is provided on the toolbar of the word processor, and by clicking “PD reading”, a PD / data correspondence table appears on the screen. The shortest shortest character string from the beginning required for identifying the registered character string group appears, and by clicking the corresponding PD, the corresponding character string is input at the position of the cursor on the word processor.
[0080]
In particular, in the case of a writing activity, since a human reads a sentence, it is desired that arbitrary data can be freely registered and read manually on a word processor. Therefore, instead of reading a PD with a pen scanner or the like, a "human" ”Reads text, so you can use a vertical bar, horizontal bar, ×, ○, various symbols, and other PDs with free patterns. The“ PD registration ”icon and“ PD read ”icon on the word processor toolbar By clicking, more data can be registered and read. By setting the number of frame settings in the PD setting table to, for example, 100, it becomes possible to register / read up to 100 frequently appearing character strings in writing work.
[0081]
For this purpose, from the beginning, in the initial setting of the PD system, the reading method may be divided into a mechanical mode using a pen scanner and a human mode using a human, and either one may be selected. In the case of human mode, it is not necessary to read with a pen scanner, so that PDs with a variety of patterns can be used. It may be prepared so that it can be displayed by the data registration unit in the PD list by the number of frames set. In this case, due to the space of the screen, the PD / data correspondence table may be displayed in a two-dimensional array, and the above-mentioned many PD fant patterns may appear in a two-dimensional array of PDs.
[0082]
The author clicks on the “read PD” icon to view the multi-dimensional, here two-dimensional, PD / data correspondence table that appears and registers with the shortest character string that appears under each PD. When the character string is roughly grasped, selected and clicked, the registered character string is automatically inputted at the position of the cursor of the word processor.
[0083]
Furthermore, as automation progresses, as the number of registered data increases, searching for the relevant data from them increases the burden on the author. Is automatically narrowed down into a reduced PD / data correspondence table in which only the shortest character string that is close to the current input character string is automatically set internally with respect to the current input character string that is completed as input is made. With the function, as the current input character string becomes a certain number of characters, the reduced PD / data correspondence table is changed from a multi-dimensional table to a two-dimensional and finally a one-dimensional table which is very easy to select. do it. Further, the reduced PD / data correspondence table may not be displayed until the reduced PD / data correspondence table is displayed until the reduced PD / data correspondence table is displayed.
[0084]
Further, in the reduced PD / data correspondence table narrowed down to a small number of dimensions, for example, one dimension, the PD list portion is hidden, and only the corresponding data is arranged and displayed in one dimension. The registered character string corresponding to the word processor may be input by selecting and clicking from the shortest character string list.
[0085]
Further, in the process of the writer inputting a character with a word processor, the current input character string becomes larger, but by selecting this and clicking the “PD registration” icon, the PD / data correspondence can be obtained. The selection operation of selecting a PD from the list of PDs in the table is omitted, and an appropriate vacant PD is automatically associated with the current input character string so that registration is performed. Then, if the function is automatically "PD readout" and the function is automatically "PD readout" and the number of dimensions is reduced to a small number of dimensions, for example, one dimension (determined by initial setting), a reduced PD / data correspondence table is obtained. Alternatively, a corresponding data list in which the PD list portion is hidden may appear.
[0086]
By doing so, the PD is used internally for registration and decoding work, and on the surface, a PD system that does not appear on the surface can be considered. It is also possible to present a presentation in which conventional font characters and PD ideographic characters are mixed. The ideographic pattern is a font in the form of a "house", a font in the form of a "person", a font in the form of a "child", and other various ideographic patterns. Register the column, and in the text of the word processor, the sentence "I talked about" music "with" friend "", and I talked about "~" with "∃" When the mouse cursor is moved to "∃", "friend" appears (this technology has already been spread to the world), and its contents can be confirmed. Also, if "ideographic expression" is deselected from the selected state in the submenu of the "view" menu of the word processor, "I talked about" music "with" friends "will be displayed. May be.
As described above, the PD system can realize a free form in reading and inputting data regardless of mechanical input or manual input by a pen scanner or the like, and realizes easy use.
[0087]
【The invention's effect】
The present invention provides a means for easily preparing and using private barcodes, which are not enough to use standard barcodes or do not allow the use of standard barcodes. It has a remarkable effect on work.
[0088]
Use 1. The school teacher keeps an "attendance book" every day. “Attend” for “attend”, “absence” for “absence”, “early” for “early departure”, and “late” for “late” are added. After school, each teacher enters the attendance data of the fifth day on the day into the computer. With a limited number of terminals, queues can quickly form. The class size is between 40 and 50.
[0089]
Since the data to be entered in the attendance book is four types of elaboration, it is unlikely that a bar code will be used, and there is no inconvenience such as pasting a barcode on the attendance book. And repeat the work of "entering the attendance data of nearly 300 people every day while checking each one." (5-10) seconds * 300 persons / 60 minutes / second = 25 to 50 minutes. When I add the waiting time, I spend one to one and a half hours a day every day, feeling no inconvenience and saying that I do this, wasting my precious time.
[0090]
When the PD system is introduced here, each teacher makes a presence / absence on the attendance book with the PD from the beginning, and later, when inputting at the terminal, only traces once for each class with a pen scanner, and the data input is completed. Will be. However, it is necessary to pay some attention in order to enjoy the convenience using the PD. First, write the PD as accurately as possible when attending the attendance book so that the data will be correctly entered later. Next, when reading the data at the terminal, 1 If you are worried about using the pen scanner twice, scan twice correctly and change the direction. When attending the attendance, if the PD is written correctly, no reading error occurs even when reading with the pen scanner, but if the writing is messy, the reading error will occur that much, and in order to avoid this, the PD written messyly Will have to be rewritten. It is still a PD system "for yourself, for yourself, for yourself". If you want to have fun, just write it right from the start. In addition, by changing the background color of the error location, by allowing the input person to manually input the location, it is possible to take busy attendance and to easily correct the error location, If the content of the attendance at the PD is to be strained, the convenience of the PD system is improved.
[0091]
Use 2. The school teacher enters the "transcript" data for each test. The same effect can be obtained when each student's grade evaluation (excellent, good, acceptable, unacceptable) or (A, B, C, D, Z) is input.
[0092]
Use 3. At universities, teachers hand out one attendance card 13 to each student at the start of class, and each student fills in necessary items such as his / her name and collects it at the end of class and hands it to the teacher. I have. After this is tough. A university usually has about 70 class members, and in a four-frame class, the data of the attendance card 13 of 280 people must be transferred to an attendance book or entered into a terminal, which puts a heavy burden on the teacher. Check the name of each student, check the attendance number, or check / mark the attending student on the attendance book / terminal input screen. This is also a very laborious task. The above-mentioned operation while turning the card must accept the trouble of the use 1 or more.
[0093]
Here, when the PD system is introduced, the teacher only has to correctly scan each card with the pen scanner. However, it is necessary to judge whether the PD system can be read by looking at the PD written by the student. It is sufficient to write all the pencils, determine whether they can be read by the pen scanner when collecting and scanning with the pen scanner, and correct only a messy card or a card that still generates a reading error warning. By explaining "machine reading," students should write carefully because they are self attendance data. Since the card handwritten by the PD remains for the present, there is an advantage that the original data is not destroyed and disappears.
[0094]
Until now, the convenience of using handwritten PDs was mentioned, but by registering a PD pattern and outputting the print with this PD pattern, the PD data is printed out in a table, and the PD data in this table is It can be read by a pen scanner in the same manner as a handwritten PD.
[0095]
In the work of counting the questionnaire, the types of data to be handled are usually small, such as YES, NO, Yes, and No. From the beginning, a questionnaire respondent can be filled in with a PD, or after collecting the questionnaire, the PD can be added to the column of each data, and the rest can be traced with a pen scanner. In addition, for example, in a format such as a payroll book, if the batch reading method of horizontal bars and columns is adopted, reading can be performed in a short time. In the conventional case, the work of reading the entire sheet with an image scanner, extracting cells at PD locations, and recognizing the contents of each cell can be fully automated, but requires a considerable amount of time, and is not practical. In the case of 1000 questionnaire sheets, it takes about 4 hours at 15000/3600 for 15 seconds per A4 sheet with an image scanner.
[0096]
If there is a mouse, pen scanner, or the like on the desk, the desk becomes too small and inconvenient, and a clean working environment can be realized by attaching the pen scanner function to the mouse. By realizing a barcode reader function with a pen scanner, a multitool that integrates a mouse and a barcode reader is realized, which is like multimedia. Since the mouse can obtain the moving distance of the mouse operation, it is not necessary to particularly provide a movement synchronization function in scanning with the integrated pen scanner, and thus the programming load on the decoder is reduced. If it is not possible to scan once, as is often seen, you will see the scene being scanned again.To avoid this, that is, to scan at the same speed, use a pen scanner for scanning. Is slightly strained, but since the movement synchronization is obtained from the mouse, it is not related to the scanning speed, so that such strain is unnecessary.
[0097]
In general image recognition processing, it takes time to perform processing such as cutting a PD on a captured image, searching for a similar pattern, and matching with a search pattern. Is once cut off, the process is the same as the process on the actual paper. If the recognition target is originally a PD, the number of recognition targets is small, so that the PD recognition time can be further shortened. Until now, many sheets of paper were read by a computer using a flat-type image scanner, and each sheet was recognized and processed over time. The paper is sequentially taken in by a machine, and then the PD scan, which requires only a short time, completes the recognition work in almost the same time as reading the actual paper.
[0098]
Regarding the time required for the PD scan, in the operation of reading a large number of actual sheets such as answer sheets and questionnaire sheets on which PDs are recorded, for example, consider a case where a bundle of attendance cards shown in FIG. 3 is set and read by a machine. In a system in which four pen scanners are provided and a plurality of attendance cards are passed under the actual paper and an image is taken / determined at a scan line portion of the actual paper, as is apparent from FIG. The required time is so short as to be necessary for the passage time of the paper, so that the PD of the paper is decrypted at the same time as the paper is taken in. Compared with the time required for area decoding by pattern matching or the like, the PD processing in the PD system is much shorter.
[0099]
In contrast to the conventional flatbed type image scanner with continuous reading function that can set a large number of papers and read continuously, a flatbed that has a continuous reading function and allows a desired number of pen scanners to be set at predetermined locations Type PD scanners are also conceivable. Provide a rod at right angles to the paper movement direction, provide a freely slidable and detachable grip along the rod, hold the pen scanner with the grip, adjust the position according to each scanning line, The scanning line is read in one pass of one sheet.
[0100]
This grip holds the rod and allows it to slide along the rod, and also allows the pen scanner to be held. Specifically, the grip is a commercially-available eye-catching clip-shaped object, such that these two are integrated at a right angle, and two clips of a hold function are provided at a right angle, and one grip for a hold is provided. The clip is slidable by tightening a rod, and the other is adapted to tighten and hold a pen scanner. For this reason, setting according to the number of scanning lines and the scanning location is easy whenever necessary, and high-speed mechanical reading of continuous PD paper is enabled.
[0101]
By adopting a PD as a questionnaire for entry of information with few recognition targets such as {，, ×, 1, 2, 3, 4}, a large number of questionnaire forms can be recognized in a short time.
