Description

Detailed Description of the Invention (Industrial Application Field) The present invention relates to a form reading processing device that optically reads and recognizes information on a form, and in particular reads mark information on a form and converts it into a character code. It relates to a device that converts and outputs it to a host device.

(Prior art) Reading slips, cards, and other various forms using an optical character reader (hereinafter referred to as OCR) and processing data on the forms using a computer is a simple method of inputting by hand. Today, it is adopted in various fields due to its ease of use.

Form data that can be read using OCR includes:
Contains alphanumeric characters, kana characters, kanji characters, image data, and marks. The data transferred to the host device as a result of reading the above information using a form reading processing device equipped with OCR includes character codes when alphanumeric characters, kana characters, and kanji characters are read. and
When image data was read, it was bit data, and when marks were read, it was ON/OFF information.

(Problem to be solved by the invention) By the way, the information entered on the form includes gender, occupation,
There is information that can be selectively inputted (hereinafter referred to as selectively inputtable information), such as age, etc., and there are conventionally the following two methods for reading this selectively inputtable information. That is,
One method is to write selective input information as characters, read and process it with a form reading processing device, and output it as a character code to a host device.The other method is to write a mark on the form. In this method, the mark is read by a form reading processing device and outputted as 0N10FF information to a host device. However, in the first method, there is a problem in that the information that can be selectively inputted must be entered as characters on the form one by one, which increases the number of inputs by the user. Also, the second
In the above method, the host device receives the received ON/
It is necessary to edit the OFF information and convert it to the character =-, which increases the load on the host device and results in a reduction in processing speed.

The present invention has been made in view of the above-mentioned problems, and its purpose is to provide a field on a form that can be selectively input, and further provide definition data that defines the format of this field. is done by marking the
An object of the present invention is to provide an effective form reading processing device that outputs reading results in character codes.

(Means for Solving the Problems) In order to solve the above problems, the present invention provides a reading device that reads information on a form, and a selection mark field that is set on the form and inputs selectively inputtable information from among the information. , selection mark field definition data that is included in the form definition data that defines the format of the form and defines the format of the selection mark field, and character codes of selection items of the selection mark field that are included in the selection mark field definition data. and a recognition processing section that reads the selection mark field with the reading device and converts the read information into the corresponding character code based on the selection mark field definition data.

(effect) The present invention based on the above configuration will be explained in detail.

By setting a selection mark field for inputting selectively inputtable information on a form, it becomes possible to input information on the form by writing a mark. The mark input into the selection mark field is read by the reading device, and the read result is sent to the recognition processing section. The recognition processing section performs recognition processing based on the selection mark field definition data based on this reading result, and sets the character code of the selection item included in the selection mark field definition data as read data.

(Example) Embodiments of the present invention will be described below with reference to the drawings.

Note that elements common to each drawing are given the same reference numerals.

FIG. 1 is a block diagram showing an embodiment of the present invention.

In the figure, a form reading processing device 1 includes an optical character reading device (OCR) for reading information written on a form 2.
) 3, a form definition data memory 4, and a recognition processing section 5. The form definition data memory 4 is a memory that stores form definition data that defines the format of the form 2.

Note that the form definition data will be described later. Recognition processing unit 5
Is the reading read by OCR3? - It recognizes the characters written on the form 2 based on the form definition data described above.

Further, the form reading processing device 1 is connected to the host device 6 and exchanges data with it.

Next, the form 2 will be explained in detail with reference to FIG. FIG. 2 is an explanatory diagram showing an example of a form according to the embodiment.

On the form 2, there are set a selection mark field 11 for inputting occupation information and a kanji field 12 for inputting name information. This selection mark field 11Fi is made up of a plurality of mark fields lla to 11d, and information can be input to the form 2 by writing a mark in any of these mark fields 11m to 11d. For example, mark field llb
If the mark is entered, it means that the information of a company employee has been entered. Furthermore, in the kanji field 12, the name is written in kanji.

Next, according to FIG. 3, the form definition data according to the embodiment will be explained in detail. FIG. 3 is an explanatory diagram showing selection mark field definition data according to the embodiment.

The form definition data 15 defines the format of the form 2 to be read, and the read data of the information on the form 2 is processed based on this form definition data 15, which is created in advance based on this form 2. You will be killed. The form definition data 15 includes selection mark field definition data 16, kanji field definition data 17, and the like. The selection mark field definition data 16 is the data that defines the information of the selection mark field 1 shown in FIG. 2, and the kanji field definition data 17 is the data that similarly defines the information of the kanji field 12 shown in FIG. be. The selection mark field definition data 16 will be explained in more detail.

The selection mark field information ID21 is an identifier indicating that the field 11 is a selection mark field. This information distinguishes the selection mark field 11 from the kanji field 12 and other fields on the form 2 (not shown). The field position 22 indicates the coordinate position of the selection mark field 11. This coordinate position is indicated, for example, by expressing the reference point at the upper left corner of the selection mark field 11 in X-Y coordinates.

1 selection field length 23 is the selection mark field 11
This indicates the size of one mark field in the field. Note that all mark fields llb to 11d have the same size. The item length 24 after selection is determined by OCR3 with a mark written in any mark field.
When this mark is read, it indicates the data length of the content to be replaced as read data based on the read mark information. As will be described later, there are multiple contents to be replaced, but all of them have the same data length. This makes subsequent processing easier.

The number of selection fields is 25, and the selection mark field is 11.
This shows the number of mark fields l1m to 11d included in the mark fields l1m to 11d. The default definition 26 is that if no mark is entered in any mark field,
It shows the default value set as read data. This default value is specifically a character code, and may be the same as or different from the content that is replaced as read data based on the mark information when any mark field is selected. Good too. By indicating the default value in this way, even when no mark is entered in the selection mark field 11,
A fixed value can be sected as read data. The content 27 after selection is any mark field.
A to 11dK marks are written therein, and data that is replaced as read data based on the read mark information is stored. Specifically, the post-selection content 27 is the character code of the selected input item (in this embodiment, civil servant, office worker, housewife, student) to be input into the selection mark field 11. The storage positions of these selected contents 27 are associated with the mark information from which the marks are read. That is, the mark information indicates the position where the mark is written, and this position corresponds to the storage position of the content 27 after selection.

Next, the operation of the embodiment will be explained.

First, the host device 6 transfers the form definition data 15 including the selection mark field definition data 16 to the form reading processing device 1.
Transfer to. The form reading processing device 1 stores the sent form definition data 15 in the temporary form definition data memory 4. Next, OCRJ reads form 2. Next, the operation after reading the selection mark field 11 will be explained mainly with reference to FIG. FIG. 4 is a flowchart showing the operation of the embodiment.

After the OCR 3 reads in which mark field l1m to 11d of the selected mark field 11 a mark is written, information indicating the position of this mark is sent to the recognition processing section 5. The recognition processing unit 5 first refers to the selection mark field definition data 16 and sets the default definition 2.
The presence or absence of 6 is determined (step 1). If a default definition has been made as in this embodiment, the default value is set as the read data of the selection mark field 11 (step 2). Next, by comparing the mark information sent by the OCR 3 and the field position 22 of the selected mark field definition data 16, as described above,
It is determined whether a mark has been written in the selected Marfield 1 (step 3).

First, by comparing the mark information and the one selection field length 23, it is determined whether or not there is a mark in the mark field Ila shown in FIG. mark field l1m
If it is determined that there is a mark, the selected content 27 located at the position corresponding to the read mark information is rewritten from the default value as the read data (step 4).
. Since the content 27 after selection is the literature code of the input item in the selection mark field 110, the read data is converted into a character code here. Then, the read data of this character code is determined as the read information from form 2 (Stella 7'6).

In step 3, if it is determined that there is no mark in the mark field llh, first refer to the number of selected fields 25 of the selected mark field definition data 16 to determine whether there is a primary mark field 11b (step 5), If so, return to Stella f3 and compare the mark information with the 1 selection field length 23 to determine whether or not there is a mark in the mark field IJb. If there is no next mark field llb in step f5, the default value set in step 2 is determined as the read information from form 2 (
Step 6). Here, since the default value is a character code, reading data of the character code will be obtained. In this way, all mark fields 11m to 11d are read and processed.

As described above, the recognition processing unit 5 obtains the reading result of the selection mark field 11 as a character code for selectively inputtable information, and the character code is transferred to the host device 6.

Further, the reading result of reading the kanji field 12 shown in FIG. 2 is recognized by the recognition processing section 5 based on the kanji field definition data 17, and read data is obtained as a character code.

In the above embodiment, the selected item length 24 in the selection mark field definition data 16 is a fixed length, but it may be a variable length as long as the data length of each corresponding content can be determined.

(Effects of the Invention) As described in detail above, according to the present invention, a selection mark field is set in which information is input by marking a mark on a form regarding selectively inputtable information, and the format of this selection mark field is changed. By providing the defined selection mark field definition data, it is possible to significantly reduce the number of inputs by the user who inputs into the form. At the same time, when the reading result is output from the form reading processing device to the higher-level device, it is output as a character code, so there is no need for editing in the higher-level device, and the burden on the higher-level device is reduced.

Furthermore, since the selected mark field is read by determining the presence or absence of a mark, the reading accuracy is improved compared to, for example, when reading Chinese characters.
