JPH0962776A - Optical character reader - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide an optical character reader which can read the characters even with no connection of a computer by providing a means which emulates the commands given from a computer, a means which stores the correct answer data, a means which compares the reading result with the correct answer data, and a means which displays the decision result of comparison. SOLUTION: A command emulator part 1 gives a request to a correct answer data loading part 3, loads the correct answer data on the business form to be read into a memory, emulates the commands given from a computer, and instructs a total control part 5 to notify the format parameter name and to start the reading of the parameter. The part 5 instructs a character recognition part 6 to recognize the characters of a scanned business form image and then receives the code data to transfer them to the part 1. The part 1 transfers the received reading result to a reading data comparison part 2 to collate them with the correct answer data. Then the collation result received from the part 2 are displayed on an operating panel 4.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an optical character reading device used by connecting to a computer, and more particularly to an optical character reading device for performing a reading inspection by the device alone.

[0002]

2. Description of the Related Art An optical character reading apparatus used by connecting with a conventional computer connects the computer, performs reading according to a command given from the computer, and sends read data to the computer.

As shown in FIG. 2 as a block diagram,
More specifically, the conventional technique is based on the higher-order interface unit 18
The command transmitted from the computer 11 in the communication control unit 1 is received by the communication control unit 12, and the overall control unit 13
The command is received from 2 and judged, the respective parts are controlled and read.

The read result is sent from the overall control unit 13 to the communication control unit 12, and from the communication control unit 12 to the computer 11.

The overall control unit 13 displays the format parameter name of the form to be read or the form identification number on the operation panel 15, and waits for an instruction from the operation panel 15. From the operation panel 15, it is possible to instruct to change the format parameter name of the read form or the form identification number or to start reading.

In addition, the overall control unit 13 includes a conveyance control unit 16
In response to the instruction, the start of conveyance of the form is instructed, and the scanner unit 17 captures the form image. Then, the character identification unit 14 is caused to perform character recognition on the scanned form image, receives the code data, and transmits it to the communication control unit 12.

[0007]

In the conventional optical character reading device used by connecting to a computer, the computer is connected and the command is given to perform reading, so that the reading inspection of the optical character reading device is performed. Even in this case, a computer was connected to perform normal reading, and the result of reading was judged.

Therefore, the present invention improves the above-mentioned drawbacks of the prior art and makes it possible to perform reading without connecting a computer in an optical character reading apparatus used by connecting to a computer. The purpose of the present invention is to eliminate the time for connecting a computer and to enable the reading inspection by the device alone.

[0009]

The present invention employs the following means to solve the above-mentioned problems.

(1) In an optical character reader used by connecting to a computer, means for emulating a command from the computer, means for storing correct answer data for determining a read result, and the read result and the correct answer An optical character reading device equipped with a means for comparing data and a means for displaying a judgment result, which enables a reading inspection by the device alone.

(2) The means for displaying the judgment result is the operation panel, and from this operation panel, the means for emulating the command is to change the format parameter name or the form identification number of the read form or to start reading. The optical character reading device according to (1) above, which is capable of giving an instruction.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows an embodiment of the present invention.
Will be described with reference to the block diagram of FIG.

In the optical character reading device of the present invention, the upper interface 18 in the prior art is replaced with the upper interface substitute section 9 only at the time of inspection, so that the main part of the optical character reading device is not changed but alone. Is possible. The operation will be described below.

When the preparation for execution of the optical character reading device is completed, the overall control section 5 requests the command emulation section 1 to receive the command. Then, the command emulation section 1 displays the format parameter name of the form to be read and the form identification number on the operation panel 4, and waits for an instruction from the operation panel 4. From the operation panel 4, it is possible to instruct to change the format parameter name of the read form, the form identification number, or to start reading. When it is instructed to change the format parameter name and the form identification number of the read form, the command emulation unit 1 changes the format parameter name and the form identification number of the read form and displays them on the operation panel 4. When the reading start is instructed, the command emulator unit 1
Requests the correct answer data loading unit 3 to load the correct answer data of the form to be read on the memory. Then, the command emulator unit 1 emulates a command from the computer and instructs the overall control unit 5 to notify the format parameter name and start reading.

The overall control unit 5 instructs the transport control unit 7 to start transporting the form, and the scanner unit 8 captures the form image. Then, the character recognition unit 6 is caused to perform character recognition on the scanned form image, receives the code data, and transmits it to the command emulator unit 1.

The command emulator section 1 transfers the received reading result to the read data comparing section 2 and compares it with the correct answer data. Then, the collation result is received from the read data comparison unit 2, and the result is displayed on the operation panel 4.

[0017]

INDUSTRIAL APPLICABILITY The present invention makes it possible to perform reading in an optical character reading device used by connecting to a computer without connecting the computer.

Therefore, according to the present invention, in the inspection of the optical character reading device, the time for connecting the control computer is not necessary, and since the inspection can be performed by the device alone, it is possible to perform the inspection in parallel at the same time. As a result, the effect of simplifying the inspection of the optical character reading device is achieved.
