DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for reading out prerecorded information visually formed on a medium such as a payment slip, performing information processing on the prerecorded information, and further outputting additional recorded information on the information processing. The present invention relates to an information processing device that prints on the medium.

[0002]

2. Description of the Related Art Generally, in this type of apparatus, a printing position for printing additional recording information in a direction orthogonal to a medium conveying direction by a printer is fixed.

[0003]

However, a slight play is set in the width direction (direction perpendicular to the conveyance direction) in the medium conveyance path so that the medium is not caught. For this reason, the medium may be shifted in the width direction, and there is a possibility that the additional recording information may be shifted from the normal area and printed.

When a frame indicating a print area of additional storage information is formed on a medium, the position of the frame in the medium may be shifted, and the additional recording information may be shifted with respect to the frame. There was a risk of being done.

Japanese Patent Application Laid-Open No. 4-319462 discloses a technique of detecting a marking line using an optical sensor and adjusting a printing position so as to print at a position matching the marking line.

However, the technique disclosed in Japanese Patent Application Laid-Open No. 4-319462 aligns the printing position with a ruled line formed in a direction intersecting the paper transport direction, and It is not possible to adjust the printing position in the direction orthogonal to the print position.

In the technique disclosed in Japanese Patent Application Laid-Open No. 4-319462, a black portion first detected by an optical sensor is detected as a ruled line. This cannot be applied to printing on paper in which different ruled lines are mixed.

The present invention has been made in view of such circumstances, and an object of the present invention is to additionally record at a regular position on a medium even if the medium is displaced in a direction orthogonal to the transport direction. An information processing device capable of printing information is provided.

[0009]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a reading means for reading an image formed on a predetermined medium, and an image recorded on the medium from the image read by the reading means. Information processing means for identifying preceding recording information and performing information processing on the preceding recording information; and predetermined additional recording information on information processing performed by the information processing means on the medium conveyed from the reading position of the reading means. A print area for detecting a position of a print area of the additional record information indicated by a frame visually formed on the medium, from an image read by the read means, A print area detected by the print area detection means with respect to a predetermined regular position by the print control means. Determine the shift amount in the direction orthogonal to the conveying direction of the medium position, and to shift the printing position in the printing means from a predetermined reference position on the basis of the shift amount.

[0010] By adopting such means, even if the printing area of the additional recording information is deviated from the normal position in the direction orthogonal to the transport direction of the medium, the actual printing is performed from the image read by the reading means.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment in which the information processing apparatus of the present invention is applied to a payment processing apparatus will be described below with reference to the drawings.

FIG. 1 is a functional block diagram showing a main configuration of a payment processing apparatus according to this embodiment.

As shown in FIG. 1, a payment processing apparatus according to this embodiment includes a CPU 1, a ROM 2, a RAM 3, a character memory 4, an image memory 5, an operation panel 6, a transport mechanism 7, an image sensor 8, and an image data generator. 9, a print head 10 and a print head driver 11 are provided. CPU 1 and ROM among these units
2, a RAM 3, a character memory 4, an image memory 5, an operation panel 6, a transport mechanism 7, an image data generator 9, and a print head driver 11 are connected to one another via a system bus 12.

The CPU 1 realizes an operation as a payment processing apparatus by performing control processing for controlling all the components based on a control program stored in the ROM 2.
The control means realized by the CPU 1 by software processing based on a control program includes a print area in addition to a well-known control means for realizing a well-known general function in a payment processing apparatus such as an information processing means. It has a detecting unit and a printing control unit.

Here, first, the information processing means performs character recognition from the image data generated by the image data generating section 9 to identify the preceding record information previously printed on the payment slip, and based on the preceding record information. Predetermined information processing regarding the payment form is performed.

The print area detecting means determines the position of a print area indicated by a frame visually formed on the payment slip as a print field of a reception number as additional recording information, and outputs the image data generated by the image data generation section 9. From image processing.

The print control means determines the amount of deviation of the position of the print area from the predetermined regular position (in the direction perpendicular to the direction of transport of the payment note), and based on the amount of deviation, determines the print position of the print head by the predetermined amount. The processing for shifting from the standard position is performed.

The ROM 2 stores a control program for the CPU 1 and the like.

The RAM 3 temporarily stores various information necessary for the CPU 1 to perform various processes.

The character memory 4 stores character data used to create an image to be printed on a payment note.

The image memory 5 is used to store the image data generated by the image data generating section 9 or to develop image data indicating an image to be printed on a payment slip.

The operation panel 6 has, for example, a key switch group and an LCD. The operation panel 6 receives various user's instruction inputs to the CPU 1 and displays various information to be notified to the user under the control of the CPU 1.

The transport mechanism 7 comprises a motor, a plurality of rollers, and the like, and transports a payment note from an insertion port (not shown) to a storage B along a transport route R under the control of the CPU 1.

The image sensor 8 is arranged to face the transport route R, and reads an image formed on a payment note transported along the transport route R.

The image data generator 9 processes the read signal output from the image sensor 8 to generate image data suitable for the CPU 1 to perform image processing. That is, the image data generating unit 9 and the image sensor form a reading unit.

The print head 10 is arranged opposite the transport path R and downstream of the image sensor 8 in the transport direction of the payment note. Then, the print head 10 is driven by the print head driver 11 and prints an arbitrary image on the payment slip transported on the transport route R.

The print head driver 11 includes a CPU 1
The print head 10 is driven so as to print an image corresponding to the image data given under the control of. Thus, printing means is formed by the print head driver 11 and the print head 10.

Next, the operation of the payment document processing apparatus configured as described above will be described according to the processing procedure of the CPU 1.

The CPU 1 starts the payment note processing as shown in FIG. 2 in response to the insertion of the payment note into the insertion opening (not shown).

In this payment note processing, the CPU 1 first
The transport mechanism 7 is operated to transport the inserted payment document to the reading position of the image sensor 8 (step ST1), and thereafter, the payment document is read (step ST1).
2). In the payment note reading process, the payment mechanism is transported by a predetermined amount by the transport mechanism unit 7 to perform sub-scanning, and the image sensor 8 performs main scanning. Then, this causes the image data generation unit 9 to generate image data based on the signal output from the image sensor 8, and stores the generated image data in the image memory 5.

Subsequently, the CPU 1 determines preceding recording information by character recognition from the image data obtained by the payment note reading process in step ST2 (step ST3), and based on the preceding recording information, for example, information management relating to payment and the like. (Step ST4). Further, the CPU 1 generates a reception number for identifying the current payment handling (step ST5). This receipt number is
This is printed on the payment form as additional record information.

Next, the CPU 1 extracts (detects) the reception number printing area from the image read in step ST2, ie, the image data generated in step ST2 and stored in the image memory 5 by the printing area detection means by image processing. (Step ST6).

Specifically, for example, an image as shown in FIG. 3 is formed on the payment note. In this case, since the column denoted by the symbol A is the reception number printing area, the CPU 1 extracts this reception number printing area based on characteristic information such as the relative positional relationship with other columns and the size. . However, FIG. 3 shows a read image when the payment document is conveyed at a regular position, and the payment document is actually shifted in a direction orthogonal to the transport direction (upward in the figure). The read image shown in FIG. Accordingly, the CPU 1 actually extracts the reception number printing area from the read image as shown in FIG. 4, for example.

When the reception number printing area is extracted, the CPU 1 calculates a distance LB from the left end of the reading range, that is, the left end of the read image to the left end of the reception number printing area (step ST7).

Subsequently, the CPU 1 prints the print head 10 from the left end of the reception number printing area in the payment document currently being processed.
The distance L2 to the left end of the recording range is represented by L1 + LB-
It is obtained by an operation LA (step ST8). Here, LA is a distance from the left end of the read image to the left end of the reception number printing area when the payment slip is conveyed at the regular position as shown in FIG. L1 is the distance from the left end of the recording range by the print head 10 to the left end of the reception number printing area when the payment slip is conveyed at the regular position as shown in FIG. Accordingly, these LA and L1 are determined to be constant values from various conditions of the structure of the apparatus, and are stored in advance in, for example, the ROM 2.

When the distance L2 is obtained in this manner, the CPU 1 stores the reception number image (stored in the character memory 4) in the image memory 5 so that the position L2 is separated from the left end of the printing range to the left end. (Combination of characters) is generated to generate image data indicating a reception number (step ST9).

Then, the CPU 1 operates the transport mechanism section 7 to transport the payment note to the print position by the print head 10 (step ST10), and thereafter performs a reception number printing process (step ST11). In this reception number printing process, the transport mechanism 7 is operated to transport the payment slip by a fixed amount while the step S stored in the image memory 5 is performed.
In this process, the image data generated in T9 is supplied to the print head driver 11 one line at a time, and printing in accordance with the image data is performed by the print head 10. This series of steps 7 to ST11 is performed by the print control means.

When the reception number printing process is completed, the CP
U1 ends the payment processing relating to the payment inserted this time.

As described above, according to the present embodiment, from the image data generated by reading the payment note by the image sensor 8 and the image data generation unit 9, the reception number printing area is extracted and the position is determined. The printing position in a direction orthogonal to the direction of transport of the book is adjusted based on the shift amount of the reception number printing area in that direction. Therefore, even if the payment slip is shifted in the direction orthogonal to the transport direction, or the position of the reception number printing area in the payment slip is shifted, the reception number can be correctly printed in the reception number printing area. .

Further, according to the present embodiment, in order to read the pre-recorded information pre-recorded in the payment form, the payment processing apparatus uses the image sensor 8 and the image data generation section 9 which are conventionally provided. Since the reception number print area is extracted and the position is determined from the image data generated by the above, it is not necessary to separately provide a sensor for extracting the reception number print area and determining the position, and can be realized with a simpler configuration. .

Further, according to the present embodiment, the reception number printing area is extracted from the image formed on the payment slip by image processing, so that the payment slip on which a plurality of columns are formed as shown in FIG. Even if there is, it is possible to respond.

The present invention is not limited to the above embodiment. For example, in the above-described embodiment, an example is shown in which the information processing apparatus of the present invention is applied to a payment processing apparatus. However, the present invention can be applied to a case where information processing on a medium other than a payment document is performed.

In the above embodiment, the reception number is exemplified as the additional record information. However, the present invention is not limited to this, and the additional record information may be any information. Also, a plurality of types of information may be included.

In the above-described embodiment, an example in which the reading / printing apparatus is an independent apparatus is shown. For example, a reading / printing apparatus having the same configuration as that shown in FIG. It is also possible to realize as a system consisting of. And in this case,
The payment processing may be executed in cooperation with the CPU of the host computer and the CPU of the reading / printing device.

In addition, various modifications can be made without departing from the gist of the present invention.
