Abstract

PURPOSE:To enable mixed reading in an arbitrary slip range by designating the kind of a slip to be read with the configuration of one kind of a format parameter group. CONSTITUTION:A slip number designation part 1 designates the kind of a slip to perform mixed reading and stores it in a memory 2. A slip number read part 4 reads the slip number on the slip, and a slip format judge part 5 verifies whether the read slip number is designated. by the slip number designation part 1 or not in comparison with the memory 2. When the slip number is designated, a format extraction part 6 extracts a slip format (slip read control information) corresponding to the slip number from a format parameter group storage part 3, a slip read part 7 reads the slip, and an output part 8 outputs the read data. When the slip number is not designated, the slip is carried by a carriage control part 9.

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, and more particularly to a heterogeneous form reading control device for reading a specified type of form when different types of forms are mixedly read.

[0002]

2. Description of the Related Art In a conventional optical character reading apparatus, when a plurality of types of forms are mixedly read, a format parameter group of a plurality of types of forms is created in advance. Then, the form number written in a position commonly set between the forms is read, the type of the form is identified by the read result, and the form data is read according to the format corresponding to the identified form.

For example, in the case where the forms A, B, and C are mixedly read from a plurality of forms as shown in FIGS. 2A to 2D, the format parameters shown in FIG. The forms A, B, and C as shown in the group are created, and the forms A, B, and C are mixedly read by determining the form format corresponding to the form number that is read. That is, all the forms included in the format parameter group were read.

The format parameter group is the form reading control information such as the reading position, the number of characters, the number of lines, and the character type on each form, and is configured for each type of form and stored in a storage device or the like.

[0005]

In the above-described conventional optical character reading device, all the forms included in the format parameter group are to be read. Therefore, a limited type of form is selected from a plurality of types of forms. In the case of mixed reading, there is a drawback that a format parameter group limited to a form format of a type to be recognized must be created every time the combination of types of forms changes.

That is, as described above, in the case of performing mixed reading of the forms A, B, and C from among a plurality of types of forms as shown in FIGS. 2A to 2D, FIG. The format parameter group shown in a) is created, and the form B,
When performing mixed reading of C and D, the format parameter group of FIG. 3B must be created, and the form format information of the forms B and C must be created in duplicate for the two types of format parameter group. did not become.

Further, the form formats of the forms A, B, and C shown in FIGS. 2A to 2D are created like the format parameter group shown in FIG. It was possible to read only the forms A, B, and C on the device and perform mixed reading. However, in this case, recognition is made due to a form selection error such as the form D being included in the forms A, B, and C applied to the device. It had the drawback of reading even the forms that you do not want to let.

[0008]

An optical character reader according to the present invention comprises means for controlling designation of a form number indicating a type of a form to be mixedly read, memory for storing the designated form number, and A means for reading a form number entered in a position commonly determined between the forms from the conveyed form, a means for determining whether the read form number is the specified form number, and And a means for reading the form according to the determination result.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of the present invention. The format parameter group storage unit 3 stores the form format corresponding to the form number in advance.

The form number designation unit 1 controls the designation of the form numbers of the forms to be mixedly read, and stores the designated form number data 101 in the memory 2.

The form number reading unit 4 reads the form number entered in a common position between the forms from the conveyed form and outputs it as the form number 401 to the form format determination unit 5.

The form format determination unit 5 compares the form number 401 output from the form number reading unit 4 with the form number designated for mixed reading, or compares and verifies with the form number data stored in the memory 2. If the specified form number is the form number 501, the form format extraction unit 6
Output to. If it is not the designated form number, a signal is output to the conveyance control unit 9, the reading of the form is canceled, and the form number of the next form is read.

The form format extraction unit 6 outputs the form format 601 corresponding to the form number 501 output from the form format determination unit 5 from the format parameter group storage unit 3.

The form reading unit 7 reads the form according to the information such as the reading position, the number of characters, and the character type indicated by the form format 601 output from the form format extracting unit 6, and outputs the form reading result as the form data 701. Output to 8.

Therefore, by designating the type of the form to be read in the form number designating section, it becomes possible to perform mixed reading of any form range, and one type including the format parameters of the form to be read By creating a format parameter group, it is possible to read all forms together.

That is, among the forms A, B, C, D shown in FIGS. 2A to 2D, the forms A, B, C and the form B,
When performing mixed reading of C and D, a format parameter group of forms A, B, C, and D, such as the format parameter group shown in FIG. 3C, is created and stored in the format parameter group storage unit 3. And form number designation section 1
Form number corresponding to the form (A, B, C) = (1, 2,
3), (B, C, D) = (2, 3, 4) is designated.

Then, the form number at a common position between the forms is read, and if the form number is the form number designated by the form number designating section 1, the form format corresponding to the form number is extracted, The form data can be read.

When the forms A, B, and C are mixedly read, even if the form D is included in the forms A, B, and C, the form number of the form D is not specified by the form format determination unit 5. It is determined that the form D is not read and is conveyed.

As described above, only the specified form can be read by the form number designating unit and the form format determining unit, and all forms can be mixedly read by one type of format parameter group. .

[0021]

As described above, the optical character reading device of the present invention includes means for controlling the designation of the form number indicating the type of the form to be mixedly read, and a memory for storing the specified form number. By including means for determining whether the read form number is the specified form number,
By creating one type of format parameter group and designating the type of form to be read, it is possible to perform mixed reading of any form range.
