That is, when the ambient environment is dark, when the illuminance sensor 141 transmits a signal corresponding thereto, the illuminator 140 operates the illuminator 140 according to the sensing result of the illuminance sensor 141 or improves the intensity of illumination. On the contrary, when the surrounding environment is bright, a clear image can always be obtained regardless of the illumination of the surrounding environment by lowering the intensity of illumination or stopping the operation of the illumination according to the sensing result of the illumination sensor 141 .

Prior to reading the image acquired in the image capturing step (S200) depending on the usage aspect, the information reading unit 300 performs a conversion step of thresholding the acquired image in order to more easily recognize the image (Image Threshold) may further include (S210). This threshold processing is also called image binarization, and by converting the acquired image into an image consisting of only black and white and corresponding 0 and 1, respectively, the information reading unit 300 reads information through the image more easily transforming it into something that can be done.

Next, by editing and reading the image acquired in the image capturing step ( S200 ), it is determined whether the paper corresponds to the comparison data previously input to the information reading unit 300 ( S300 ). That is, the information reading unit 300 determines whether the paper can be read or the paper cannot be read. This paper determination step (S300) can be determined through any process if it can be determined whether the marking paper 1000 is readable or the marking paper 1000 that cannot be read. It is possible to determine the marking paper 1000 through the same process.

8 is a diagram illustrating a process of editing a captured image according to the present invention.

In the paper determination step (S300), the marking paper 1000 supplied last among the images captured in the capturing step (S200), that is, the marking paper 1000 seated on the top of the stacked marking paper 1000. In order to extract only The arrangement angle of the uppermost marking paper 1000 and the area of the marking paper 1000 are checked (S310). To this end, recognition marks such as the symbol mark 1200 or the clock mark 1300 of the marking paper 1000 seated on the top among the captured images are recognized, and the placement angle of the marking paper 1000 placed on the top through this and It is possible to check the area of the paper corresponding to the symbol mark 1200 or the clock mark 1300 among the data previously input to the information reading unit 300 . That is, a recognition mark such as a symbol mark 1200 or a clock mark 1300 provided for each marking paper 1000 is formed on one side of the marking paper 1000, and the recognition mark of the marking paper 1000 and corresponding Information such as the area of the marking paper 1000 may be previously input to the information reading unit 300 . Accordingly, when the information reading unit 300 recognizes the recognition mark of the marking paper 1000, the current marking paper 1000 is disposed at a certain angle, and the overall shape and area of the marking paper 1000 based on the recognition mark etc. will be clearly visible.

Next, in the mark recognition step (S310), from the captured images in consideration of the arrangement angle, shape and area of the marking paper 1000 determined based on the recognition mark such as the symbol mark 1200 or the clock mark 1300 Edit to extract only the image of the marking paper 1000 arranged on the top (S320). Even if you do not extract the image separately, there is no big problem in performing the subsequent process, but it is better to edit it so that only the image placed at the top is extracted in order to be more accurate and prevent the problem of reading errors in advance. In addition, depending on the usage aspect, the angle may be adjusted so that the extracted angle has an angle according to a preset standard.

Next, by comparing the image of the marking paper 1000 extracted through the image edited through the editing process (S320) and the comparison data pre-entered into the information reading unit 300, the supplied marking paper 1000 is comparison data It is determined whether the marking paper 1000 is readable by checking whether there is corresponding comparison data among them (S330). To this end, at least one or more comparison data capable of discriminating the readable marking paper 1000 is previously input to the information reading unit 300 . This may be determined by whether the recognition mark or data box marked on the marking paper 1000 is checked. For example, it is possible to determine whether the marking paper 1000 is read by comparing the extracted image with the previously input comparison data with the recognition mark or logo 1100 marked on the marking paper 1000 . In another embodiment, in the case of the marking paper 1000 for the test answer sheet, the first determination is made through the recognition mark, and the second determination is made through the code of the subject checked in the data box 1400, and the marking paper 1000 is It is possible to determine whether to discriminate and compare data to be applied to information reading. The above-described two examples are merely exemplary and are not limited to a method of determining the marking paper 1000 .

In this way, the paper identification step (S330) according to the present invention determines whether the captured image is a readable paper based on the comparison data for various previously inputted marking paper 1000, and at the same time, the type of the place where the marking paper 1000 is applied. can be checked. In one embodiment, when it is determined as a readable lottery ticket as a result of the determination, the paper corresponding to which lottery ticket is also determined.

Depending on whether the paper can be read in the above-described paper determination step (S300), the information reading step (S400) may be performed, or at least some of the preceding steps may be re-performed for re-recognition. The information reading step (S400) will be described in more detail later, and first, the re-recognition step will be described in more detail as follows.

First, if it is determined that reading is impossible in the paper determination step ( S300 ), an error occurrence signal is generated visually or audibly to the user or manager through the notification unit 330 . Also, the information reading unit 300 transmits a paper supply stop signal to the paper supply unit 500 to temporarily stop the paper supply of the paper supply unit 500 . This is to prevent mixing of the normally read marking paper 1000 and the normally read marking paper 1000 .

Various cases may occur in which it is determined that the paper is not suitable in the paper determination step ( S300 ). Among them, in consideration of the case where the determination is not made due to a program error, the determination step (S300) is first performed once again.

That is, the process of recognizing the first captured image again (S310) to the determining step (S330) is sequentially performed once again. At this time, when it is determined that the readable marking paper 1000 is determined, the process proceeds to a determination step (S400), and the information reading unit 300 transmits a signal to the paper supply unit 500 to resume paper supply. If necessary, it may be determined again by changing the sharpness of the image by re-performing from the threshold processing step (S210).

However, if it is determined as an error even after going through the mark recognition step (S310) and the determination step (S330) again, a notification is generated to the user or the manager through the notification unit 330, and the information reading unit 300 is the paper supply unit ( 500) to keep the paper feed stop.

Thereafter, in consideration of the possibility that the image capture was not performed smoothly, the information reading unit 300 transmits a signal to the image capture unit 200 to acquire a new image in the capturing step (S200), and using it to determine the paper (S300) is performed again. At this time, when it is determined that the readable marking paper 1000 is read, the reading step ( S400 ) is passed, and the information reading unit 300 transmits a signal to the paper supply unit 500 to resume paper supply.

However, if it is repeatedly determined as unreadable paper even after capturing a new image, an error occurs and a removal request signal is generated to the user or administrator through the notification unit 330 . The removal of the marking paper 1000 may be directly performed by a user or an administrator, or the paper removal unit 150 may be driven to automatically remove the marking paper 1000 .

At this time, when the marking paper 1000 is supplied, accurate determination may not be made even if the marking paper 1000 deviates from the seating unit 110 by more than a certain area. In this case, the editing step S320 or the determination step S330 ), it is possible to transmit a notification signal requesting the user to adjust the paper placement position or angle instead of removing the paper.

After removing the marking paper 1000 that cannot be determined as described above, the information reading unit 300 transmits a signal to the paper supply unit 500 to resume paper supply. If the angle and arrangement change of the marking paper 1000 is requested, the user or manager performs the angle and arrangement change of the marking paper 1000 and then the capture step (S200) to the paper determination step (S300) are performed again.

As described above, the error notification generated when an error occurs may indicate each situation in various ways. In one embodiment, the signal for each error may be accurately transmitted by visually indicating through the color and blinking method of the LED 331 or by generating various warning sounds through the speaker 332 . In addition, depending on the usage mode, the type of error may be accurately described on the screen display unit, or a countermeasure may be provided together. Of course, each error occurrence signal may be transmitted to the portable terminal of the user or manager through the communication unit 320 included in the information reading unit 300 depending on the usage aspect.

When it is determined that it is readable through the above process, the information reading unit 300 reads the information of the marking paper 1000 through the information of the data box 1400 checked on the marking paper 1000 (S400) and A read result is output (S500).

These information reading (S400) and output (S500) processes may be classified in various ways depending on the usage of the marking paper 1000, and in one embodiment, for lottery such as lottery, for surveys and test answer sheets, etc. can be classified. Accordingly, the process of reading information (S400) and outputting (S500) for each embodiment will be described in more detail as follows.

(For reading lottery paper)

Since there is no fixed correct answer when used for reading lottery paper, etc., when it is determined as readable paper in the paper determination step ( S300 ), there is no need to compare it with separate comparison data. Accordingly, in the information reading step (S400), the information reading (S400) is completed by extracting the information input to the data box 1400 of the marking paper 1000. That is, the information reading ( S400 ) is completed by extracting the number of games desired by the user and the number input to each game.

When the lottery paper is used, the result paper on which the result value is displayed is output through the paper output unit 410 because the user has to keep the result paper to prove it (S500). At this time, depending on the usage mode, the result value can be simultaneously output to the screen display unit so that the administrator or user can check the paper output at the same time, or it can be transmitted to the portable terminal using the communication unit 320 included in the information reading unit 300. .

As such, when checking the lottery paper using the reading device 10 and the reading method according to the present invention, a separate paper supply unit 500 is not provided because a large amount of the marking paper 1000 is not supplied, and the user or The manager may manually supply the marking paper 1000 to the seating unit 110 .

(for surveys)

You can conduct a survey on a variety of things at various places, such as airports, hospitals, or schools. Even in this case, if the reading device 10 and the reading method according to the present invention are used, the questionnaire result can be obtained more easily and quickly. This process will be described in more detail as follows.

In the case of the marking paper 1000 for survey, there is no set correct answer as in the case of the lottery, but since statistical results according to a plurality of answers are required rather than the result value of each individual marking paper 1000, there are some differences from those for the lottery in this part .

Accordingly, the information reading unit 300 is the number of supply of the marking paper 1000 until a preset time or a set number of the marking paper 1000 is supplied, or the additional marking paper 1000 is not supplied for a predetermined time. And read the display result of each data box 1400 and accumulate the result value (S400).

The result data accumulated by the above process is output on paper through the paper output unit 410 according to the request of the user or administrator, displayed on the screen display unit, or transmitted to the portable terminal through the communication unit 320 (S500) ). In the output data output at this time, statistical data such as the number of supplied marking paper 1000, questionnaire questions, and the number of times of marking according to each question may be output in various forms according to a pre-entered program.

(for exam answer sheet)

In the case of using the marking paper 1000 for the test answer sheet, if the marking paper 1000 is determined as a readable paper in the paper identification step (S300), it must be determined whether it is the answer sheet for the type of test or the test subject, Accordingly, a process of comparing using comparison data including a correct answer corresponding thereto among the comparison data previously input to the information reading unit 300 is required. Accordingly, a process differentiated from the aforementioned lottery ticket and questionnaire survey is required, which will be described in more detail as follows.

9 is a flowchart in which the information reading step according to the present invention is classified in more detail.

First, in the information reading step ( S400 ), as shown in FIG. 9 , the following process may be performed.

First, the information checked in the data box 1400 of the marking paper 1000 is extracted using the image captured by the information reading unit 300 (S410). Here, the data box 1400 of the marking paper 1000 may include an area in which the name of the examinee, the question number of the question, the answer number for each question number, the corresponding code according to the test subject, etc. can be input. . That is, information input to the data box 1400 may be extracted to extract information such as the name of the examinee, the test subject, the number of the question, and the answer number indicated for each question.

Next, it is selected to apply comparison data having a code corresponding to the code extracted from the data box 1400 among the comparison data previously input to the information reading unit 300 ( S420 ). That is, the various comparison data previously input to the information reading unit 300 each have a pre-given unique code, and compare the code value extracted in the marking data extraction step (S410) with the unique code to select the corresponding comparison data. will be. In one embodiment, when the examinee inputs 01 in the code check field of the marking paper 1000, it is extracted in the marking data extraction step (S410), and 01 of various comparison data previously input to the information reading unit 300 Comparison data having a unique code of

Next, by comparing the marking data extracted in the marking data extraction step (S410) and the comparison data selected in the data application step (S420) to extract the result value for the comparison result (S430). The step of extracting the result value ( S430 ) will be described in more detail as follows.

10 is a flowchart in which the step of extracting a result value according to an embodiment of the present invention is classified in more detail.

First, by comparing the comparison data and the marking data, it is determined whether the match is correct or not, and the correct answer is calculated (S431). That is, when the comparison data and the marking data match, the correct answer is calculated, and when the comparison data and the marking data do not match, the answer is calculated as an incorrect answer.

Next, a score corresponding to each question is given according to the result calculated in the correct answer calculation step (S431) (S432). The comparison data previously input to the information reading unit 300 includes a correct answer for each question and a score given to the corresponding question. Accordingly, the comparison data and the marking data are compared to determine whether they match, and a score is given accordingly.

Although the step of calculating the correct answer ( S431 ) and the step of assigning a score ( S432 ) are sequentially described for convenience of explanation, it is obvious that they may be performed simultaneously.

When the extraction of the result value is completed through the above process (S430), the result value is output in various ways (S500). In this output step (S500), the number of correct answers compared to the total number of questions and scores can be output for each test taker, and the test taker can store it in the information reading unit 300 or through the communication unit 320 included in the information reading unit 300 . Alternatively, it may be transmitted to the administrator's mobile terminal or a separate external storage device. Of course, the test results may be simultaneously displayed on the image display unit 420 .

In addition, if necessary, after accumulating result data for each test taker, individual result values and average scores for a plurality of subjects for each test taker may be output on a single sheet of paper.

The above-described embodiments classify only representative embodiments among various embodiments, and do not limit the use thereof, and it is obvious that more various marking paper 1000 can be read using similar or different processes.

As described above, those skilled in the art to which the present invention pertains will understand that the present invention may be embodied in other specific forms without changing the technical spirit or essential characteristics thereof. Therefore, it should be understood that the above-described embodiments are illustrative in all respects and not restrictive.
