Abstract

(57) [Summary] [Structure] In the printing mechanism of an optical character reader that reads the characters entered on a slip and prints the corresponding serial number, the printing and
A ROM 4 that stores character shape information, a RAM 1 that stores information about the writing direction of characters to be read with respect to the conveyance direction,
It also includes a pattern generator 3 that selects a character shape according to the reading character direction. [Effect] A serial number can be printed in accordance with the rotation direction of the characters written on the slip with respect to the conveyance direction. Therefore, when a large number of slips are processed at once and the read data is compared with the slips, the work can be carried out efficiently.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

The present invention relates to the printing mechanism of an optical character reading device, and in particular to reading characters written on slips, etc. The present invention relates to a printing mechanism that prints a predetermined serial number at a predetermined location on a slip.

0002

[Conventional technology]

In the printing mechanism of a conventional optical character reading device, as shown in FIG. Performs a series of procedural controls such as optical reading, character type selection, and print head drive. The ROM 4 stores the print character type as information. pattern generator 3 In response to a print start command from the CPU 2, the drive circuit 1 starts printing based on the character shape information from the ROM 4. 0 to control the print head 6. By repeating this control, a series of A number will be printed.

0003 Next, regarding the form of the target slip, reading of the entered characters, and printing of the serial number. This will be explained with reference to FIGS. 3(a) and 3(b). Figure 3(a) shows the regular form of the slip 12. , the input characters 13 for reading are in the upper left part, and the serial number 14 to be printed is in the lower right part. It's in the part. Further, the slip conveyance direction is assumed to be 15. Now, the slip 12 is in the transport direction 15. On the other hand, when placed vertically, the position of the slip 12 is 90 degrees, as shown in Figure 3(b). The serial number 18, which is printed regardless of whether it is rotating, is printed in the same direction as in Figure 3(a). It was not printed in 14A, which is the correct position and orientation.

0004

[Problem that the idea aims to solve]

The conventional printing mechanism described above prints the serial number 1 on the slip after the reading operation is completed. 4 has a character shape that is aligned in a certain direction with respect to the conveyance direction 15 of the slip. Slips with characters written at 90 degrees to the right with respect to the transport direction 15, as shown in b) When reading, the serial number 18 is printed in the opposite direction to the input character 13. It has the disadvantage of being

[0005]

[Means to solve the problem]

The printing mechanism of the optical character reading device of the present invention reads the characters written on the slip and corresponds to the characters written on the slip. The printing mechanism of an optical character reader that prints serial numbers stores printing and character type information. The ROM stores information about the writing direction of the characters to be read in relation to the transport direction. A pattern generator that selects the character shape according to the direction of the read character. including.

[0006]

【Example】

Next, the present invention will be explained with reference to the drawings. Figure 1 shows a block diagram of one embodiment of the present invention. This is a diagram. In FIG. 1, the same symbols as in FIG. 2 have the same configurations and functions. vinegar That is, in this embodiment, RAM1 is added. RAM1 is set in the transport direction in advance. 15, the direction of the characters 13 written on the slip 12 is stored as information, and it is easy to read. Immediately after starting the pattern generation, the CPU 2 refers to the RAM 1 and uses the direction information as a pattern generator. It is transmitted to the controller 3. The pattern generator 3 uses the information from the ROM 4, Select the character shape with serial number 14 aligned in the same direction as the slip character entry, and drive circuit 5 The print head 6 is controlled through. By repeating this control, a serial number is added to the document. 14 is printed.

[0007]

[Effect of the idea]

As explained above, the present invention is designed to Since it has a RAM that stores the direction, the number of characters entered on the slip in relation to the conveyance direction is A serial number can be printed according to the direction of rotation. Therefore, a large number of documents After batch processing, you can perform the work efficiently when comparing the scanned data and the invoice. There is an effect that can be achieved.
