Description

[Detailed Description of the Invention] The present invention reads characters, numbers, symbols, etc. written on a form, adds consecutive numbers to the read data, and stores the data in a floppy disk device or the like. The present invention relates to a method for canceling read data stored in a floppy disk device of a document reading device (for example, an optical character reading device).

Recently, the number of fields in which various forms, such as electricity, gas, and water bills, are read and processed by a form reading device such as an optical character reading device has increased significantly.

In such fields, there is a trend toward multifunction terminals in which form reading devices are equipped with various types of intelligence.

Therefore, some of these form reading devices have some calculation processing functions.

In such a form reading device, the read data is stored in a storage device such as a floppy disk device, and after the read data is edited or corrected, it is sent to the center or host. , and send it to a higher-level device, etc.

The present invention provides a method for making corrections to this storage device.

The applicant has conventionally proposed a form reading device that is capable of making corrections, and this conventional example will be described below.

Documents such as invoices are read by a document reading device such as an optical character reader, and sequential numbers are assigned to each data unit according to the reading order of the documents and stored in a storage device such as a floppy disk device. .

In this way, the documents are read sequentially, a serial number is added to the read data, and after all the read data to be processed is stored in a storage device such as a floppy disk device, the contents stored on the floppy disk are Display or print out.

The operator looks at the displayed or printed data and detects whether or not the corresponding slip has been read.

If an unnecessary slip is found among the read slips, cancellation processing is performed on the read data corresponding to the slip stored in a storage device such as a floppy disk device.

That is, this read data cancellation process has conventionally been performed in the following manner.

First, the form reading device is set to cancel mode.

After setting the cancel mode, use the keyboard to specify the serial number added to the read data of the slip to be canceled.

At the same time, it sequentially reads read data from a storage device such as a floppy disk device, compares the sequential numbers in the read data with the sequential numbers specified from the keyboard, and stops reading the storage device when they match. Then, the read data of the corresponding serial number part is set to write mode and a flag bit is added.

This terminates the cancellation process.

However, in this method, the read data to be canceled is specified only by a number, so
There is a possibility that cancellation processing may be performed on other read data by mistake.

Therefore, it is an object of the present invention to provide a method for canceling read data in a new form reading device that eliminates the above-mentioned drawbacks. An instruction is input using a number and a part of the read data, and the input data is compared with the corresponding part of the data read from the storage device, and cancellation processing is performed on the data that matches. Achieved by doing.

Hereinafter, the present invention will be explained with reference to the present invention.

FIG. 1 shows the format of read data stored within the storage device of the present invention.

As shown in the figure, a serial number is added to each read data to form one piece of data.

In the present invention, as shown in FIG. 2, a serial number and a part of the read data are specified when canceling the read data.

Next, one embodiment of the present invention will be explained with reference to FIG.

First, the normal form reading mode will be explained.

1 is a form in which letters, numbers, symbols, etc. are stored.

This form 1 is read by the form reading section 2 based on format information from the format control circuit 3, and is inputted to the data register 4 with a serial number added thereto.

In the data register 4, serial numbers and data are stored.

This serial number and data are input to the AND gate 17 by the control unit 11.
A floppy disk device 7 is written through the write circuit.
written to.

At the same time, this read data is branched from the write circuit and enters the print control section along with the serial number, and is sent to the print section 2.
4 is printed.

In addition, when reading form 1 such as a sales slip among the data accumulated in the data register 4, the read data, that is, stored in the data register 4, is used to calculate the total sales of this read form. Only the calculated amount is read out from the data register 4, inputted into the counter 9, and sequentially added up.

In this way, the form 1 is sequentially read and written to the floppy disk device 7, and the read contents are printed by the print section 7.

Similarly, the counter 9 also counts the numerical value desired to be read.

In this way, when the reading of the form 1 is completed, the close signal 15 is manually inputted using a key, for example, so that the control section 11 controls the count control section 10, writes the accumulated numerical value to the floppy disk device 7, and simultaneously prints the data. Part 24
The process ends by printing.

Thereafter, the read data stored in this floppy disk device 7 is sent to the center via a host device or circuit by controlling a write circuit 8.

Next, when a situation arises in which the read data must undergo cancellation processing, the present invention performs the following procedure.

After reading the form 1 and before closing it, a correction mode signal 14 is issued to put all gates and control units into the correction mode.

Thereafter, using the key 13, the user specifies the serial number and part of the read data for the read data to be corrected.

This data is stored in the data register and displayed on the display 5.

Further, the floppy disk device 7 is placed in a read mode by the control section 11.

The serial number and part of the read data stored in the data register 4 specified by the key 13 are input to the comparator 21 because the AND gate 16 output from the data register 4 is open.

The comparator 21 sequentially compares the serial number and read data read from the floppy disk device 7 with the serial number designated by the key 13 and the read data.

Therefore, in the floppy disk device 7, the read data and serial number are inputted for comparison via the read circuit 8 until a match signal is obtained at the output of the comparator 21.

When a match signal is output from the comparator 21, this signal is transmitted to the control unit 11, which stops reading from the floppy disk device 7 and immediately activates the write circuit 6 to be able to write to the storage location of the read data that matches. do.

In this way, when the write circuit 6 is activated, the flag bit created by the flag bit creation circuit 20, which is activated by the match signal from the comparator 21, is added to the read data as shown in FIG. Indicates that the data is canceled data.

On the other hand, the read data when a match is found is stored in the register 22, and like the data register 4, only the part of the read data that is added by the counter 9, such as the amount of money, is extracted and sent through the gate 19. Decrement counter 9.

By doing this, the contents of the counter 9 are obtained by subtracting the amount corresponding to the canceled data, and the cumulative amount obtained by removing the canceled data is obtained.

In this manner, when the cancellation process is completed, the close signal 15 is issued, thereby completing the cancellation of the read data.

As described above, the present invention prevents necessary read data from being erroneously canceled by specifying the data to be canceled using the serial number and part of the read data.
