Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an interactive mark correction method, and more particularly to a method for interactively detecting and correcting errors in marks written on a form.

The OMR device uses a form as shown in FIG. 1, and an operator adds marks to the form according to the data to be processed and in a predetermined manner. In this example, the form consists of a customer number, a slip number, multiple sets of product number, quantity, and unit price, year, month, and date, etc., and the numerical value is represented by placing a vertical line around the corresponding number in the group of numbers.
The form on which data has been written is subjected to an OMR device to optically read the marks, and the read data is sent to a computer (not shown) or the like to be stored and/or processed. When marking such forms, dark thin errors, no mark errors, double mark errors, etc. occur. dark thin error
DTE is when detecting the presence or absence of a mark by sorting the reflected light from the mark using a threshold value.If the threshold value is set to a value for a normal dark mark, it cannot be detected; This refers to something that can be detected by setting a value corresponding to the object.Such marks are written thinly and can be corrected by making them darker. No mark, double mark error NME, DME is usually divided into multiple pieces (vertical columns in Figure 1) in the OMR form, and it is a promise to write one mark on each piece, but when I checked it, there was only one piece. This refers to cases where there are two marks (double mark) or no mark (no mark). Parity errors are other types of errors, but in any case, when an error is discovered, the form is ejected to the reject statistics car.

That is, Fig. 2 shows an overview of the form movement path of the OMR device, where 10 is the hopper part of the form SH, 12
14 is a reading head, 14 is a feed roller provided on the form transport path, 16 is a reject stacker, 18 is an accept stacker, and 19 is a valve. Hopper part 1
0 and is read by the reading head 12, and a form in which no entry error has been found is sent to the accept stacker 18 side by a valve 19, whereas a form in which an entry error has been found is sent to the reject stacker 16 by the valve 19. Sent. Workers later search for errors in the rejected forms, make light marks with a pencil and darken them.
For double marks, marks are written and unnecessary marks are erased based on the original data, but this work is time-consuming.

The present invention aims to improve these points.
If an error is found, the relevant part of the form can be viewed on the CRT.
The data is displayed on a display, etc., and the location of the error is indicated by blinking, etc. The worker sees this and instructs the operator to write in and erase the mark using a light pen, etc. As a result, the correct data is input into the computer, and on the other hand, the correct data is inputted into the computer. Certain forms remain as they are without being modified, and the modifications made are memorized. In this way, data entry will be performed accurately, and forms with incorrect entries will be returned as is, along with a report on the corrections made, and no trouble will occur between the data entry requester and the contractor. Next, this will be explained in detail with reference to the embodiment shown in FIG.

In FIG. 3, 20 is an OMR, that is, an optical mark reading device, and 22 is a reading section including a reading head. 24 is a computer for processing read data, and includes a buffer memory 26 for OMR output data, a data check mechanism 28, an error information creation mechanism 30, an output information creation mechanism 32, and a modification mechanism 34 for the contents stored in the buffer 26. A display device 36 includes a screen format creation mechanism 38, a screen buffer 40, and a display device 42 such as a CRT.
44 is a light pen, 46 is a keyboard, and including these, the display device 36 is assembled as shown in FIG.

To explain the operation, collect the marked forms, organize them so that there are no left and right irregularities, and perform OMR.
After initial processing of the form is carried out, the reading section 22 reads the mark. The read data is written to the buffer 26, and the written data is checked by the mechanism 2 for dark thin, no mark, double mark, parity check, etc.
8 will do it. If there is no error, no warning will be displayed and the form will be stored in the stacker. If an error is found, check mechanism 28 produces an output and mechanism 3
0 creates error information according to this output. For example, if the number column (piece) in the first place of the slip number of the form SH shown in FIG.
outputs. This mark position information and information indicating that this information relates to the slip number are input to the screen format creation mechanism 38 of the display device 36, where the mark position plus "slip number" is input.
A composite image signal consisting of equal characters and frame information, ie, format information, is created, and this signal is written into the screen buffer 40. The control device of the CRT42 repeatedly reads out this screen buffer in synchronization with the scanning.
Display the form slip number part on the CRT screen. Fourth
The figure schematically shows this, but in this example a block consisting of a number of pieces, such as product numbers, is displayed. Furthermore, the screen format creation mechanism 38 also generates a mark indicating the position of the piece in which the error was found and information indicating the type of the error based on the output from the mechanism 30, writes them to the screen buffer 40, and displays the information on the display. 42. The mark indicating this position is ※ or ? You can use any mark or cross mark, but it is easier to see if you use blinking. The type of error is indicated by displaying a no mark, double mark, etc. in the appropriate place on the CRT screen.

When such a display appears, the operator begins correction work. Note that it is also effective to emit a warning sound in addition to the visual display, and in this case, the reading operation of the next form is interrupted. The operator looks at the screen of the display 42, learns the location and type of error, takes out the form that is now at the top of the stacker, and checks the location of the error. Dark thin marks, double marks, etc. often occur when the operator notices a mistake and uses an eraser to erase the mark in the correct position, but the erasure is insufficient. This makes it easy to infer the correct data. If it is difficult to guess the correct data, refer to the original data, and once the correct data is determined, the operator holds a light pen 44, etc., and if one of the marks is to be erased, touches the mark to be erased with the light pen and erases it. Press the button to command. Coordinate information can be obtained by contacting the light pen, and the type of modification can be determined by pressing the button, so that the screen format creation mechanism clears the memory element of the screen buffer 40 that stores the mark. As a result
The mark is erased from the display surface of the CRT 42, and this information is also sent to the computer 24, which clears the memory element of the OMR buffer 26 via the buffer correction mechanism 34. If there is no mark, place the light pen 44 on the desired position on the screen of the CRT 42 and press the "write mark" button. As a result, the memory elements of the buffers 40, 26 corresponding to the positions are set and marks are written. Other modifications also apply. Coordinates can be entered using keyboard 4.
This may be done by operating step 6. The data is corrected in this manner, and the output information creation mechanism 32 of the computer 24 outputs error-corrected clean data, and the details of the data correction that has been made are recorded in the memory built into the mechanism 34 or, although not shown, in a printer, etc. Run and print out.

FIG. 5 shows another example of the display by the display 42. In this case, all displays are made using letters, numbers, etc., and a * mark appears in the third column of the quantity where the error occurred, and this is linked. Such a display is also possible by modifying the output of the error information creation mechanism 30 and the screen format creation mechanism.

This system does not distinguish between forms with errors and forms without errors, and outputs them to the same stacker. The form with the entry error is not corrected, but the entry error is left as it is, and the contents of the memory are corrected. After correcting the memory, press the restart button and start reading the next form. This method is suitable when a completed form is given and a worker or vendor is asked to input information into a computer. That is, since the form is returned as is with the corrections made without making any corrections, the client can easily check the form and find out whether it is correct or incorrect and who is responsible for it.

As described in detail above, according to the present invention, errors in data entry can be easily corrected, and since no corrections are made to the form, situations such as loss of evidence do not occur, and the present invention is extremely suitable.
