Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a medium processing device for processing a medium such as a passbook provided with a bar code.

[0002]

2. Description of the Related Art Conventionally, when a passbook is inserted into a passbook entry machine as a medium processing device installed in a financial institution, transaction information is sequentially printed. When the last line of the page is printed, the passbook is conveyed to the turn page unit in the apparatus, and the page is changed there. And after the page break,
It is confirmed whether the predetermined page has been turned.

For this confirmation, a page mark printed on each page of the passbook is used, and by optically reading this page mark, which page is opened. It is determined whether or not there is. Then, if it is determined that the predetermined page is turned, the page is printed, and if the predetermined page is not turned, the passbook is again passed to the turn page unit. Carry and page break again.

The page mark is indicated by a bar code, and the bar code has a horizontal bar printed with the bar parallel to the reading direction of the bar code. There are two types: a code and a vertical bar code in which a bar is printed in a direction orthogonal to the reading direction of the bar code. Further, the vertical bar code can identify more pages than the horizontal bar code.

Since the page identification method is different between the horizontal bar code and the vertical bar code, a passbook entry machine that handles a passbook in which the vertical bar code is printed uses the vertical bar code. It is set so that it can only be read, and a passbook entry machine that handles a passbook on which a horizontal bar code is printed is set so that it can only read the horizontal bar code.

[0006]

In the above-mentioned conventional passbook entry machine, the number of pages of the passbook tends to increase with the increase in the number of subjects of the passbook in recent years, and the passbook using the horizontal bar code is not available. , There is a tendency to shift to the vertical bar code.

Therefore, a bank which used a passbook having a horizontal bar code printed thereon will shift to a passbook having a vertical bar code printed thereon. During the transition period of the passbook, two page marks, a horizontal bar code and a vertical bar code, coexist. Conventionally, horizontal bar code or vertical bar
Since only one of the two barcodes could be read, as a countermeasure against that, the passbook recorder was used for both horizontal and vertical barcodes. -There is a method of setting so that the code can be read.

However, since the horizontal bar code and the vertical bar code have different page identification methods, it is not possible to read both the horizontal bar code and the vertical bar code at one time. Therefore, since it is necessary to switch the bar code reading method, it is necessary to determine in advance whether the horizontal bar code or the vertical bar code is printed on the inserted passbook. , The customer or the operator had to enter the data in the device.

As another method, there is a method of setting the apparatus to automatically read both the horizontal bar code and the vertical bar code. In this case, for example, the vertical bar code is set to be read first, the bar code is read with this setting, and if the bar code cannot be read, the horizontal bar code is set to be read next and the bar code is read. . However, in this method, the page marking operation is performed twice by switching the page mark reading setting. Therefore, whichever of the above methods is used, it takes time or labor.

[0010]

In order to solve the above-mentioned problems, a solution means provided by the present invention is to optically read a bar code printed on a medium with an image sensor, and read the medium from the read result. In a medium processing device for analyzing the number of open pages, a black-and-white judging section for judging black-and-white for each pixel of a bar code read by an image sensor and a judgment result of the black-and-white judging section. The data for each line is parallel to the vertical bar code data in which the bar is oriented in the direction orthogonal to the bar code reading direction and to the bar code reading direction. A memory unit for storing both the horizontal bar code data in which the bar is oriented in the direction and the horizontal bar code data are recalled from the memory unit to obtain the bar code. The length in the direction orthogonal to the reading direction is determined, the direction of the bar is determined from the length, and if the determination result is vertical, enter A vertical bar code data is called from the section to analyze the number of pages indicated by the bar code, and when the judgment result is horizontal, a control section for analyzing the number of pages indicated by the bar code. Is provided.

[0011]

The black-and-white judging section makes a black-and-white judgment for each pixel of the bar code read by the image sensor. Then, based on the judgment result of the black-and-white judging unit, the data for each line is identified as vertical bar code data in which the bar is oriented in the direction orthogonal to the reading direction of the bar code. , The horizontal bar code data in which the bar is oriented in a direction parallel to the reading direction of the bar code is stored in the storage unit.

Next, the horizontal bar code data is called from the storage unit, the length in the direction orthogonal to the bar code reading direction is determined, and the direction of the bar is determined from the length. If the determination result is vertical, the vertical bar code data is called from the storage unit to analyze the number of pages indicated by the bar code.

On the other hand, if the determination result is horizontal, the horizontal bar
The number of pages indicated by the bar code is analyzed from the data.

Connected to the preprocessing unit 20 and the control unit 16,
A black-and-white determination unit 21 that determines whether each pixel read by the image sensor 19 is white or black is configured. The image sensor 19 reads the bar code 28 in the direction orthogonal to the carrying direction of the passbook 3.

A motor control section 22 is also connected to the control section 16. This motor control section 2
2 is ON / O to the motor 24 according to an instruction from the control unit 16.
An FF signal, a timing signal for rotating the motor 24, etc. are generated and sent to the motor driver 23. The motor driver 23 rotates the motor 24 according to a signal from the motor control section 22. The motor 24 is a motor for transporting the passbook 3, and by rotating the motor 24, the transport roller shown in FIG.

Next, the operation of detecting the opened page of the passbook 3 in the above configuration will be described with reference to FIGS. 1, 2, 3, and 4.
A description will be given according to the flowchart of FIG. 7 with reference to FIGS. FIG. 7 is a flow chart showing the bar code reading procedure of the passbook entry machine according to the embodiment. The first line of the image sensor 19 is the tip 3a of the passbook 3 shown in FIG.
When the passbook 3 is inserted into the passbook entry machine 1, the control unit 16 causes the light source 17 to emit light.

In step S1, the control unit 16 controls the tip 3a.
The passbook 3 is conveyed until is positioned below the image sensor 19. Then, the light from the light source 17 is reflected on the paper surface of the passbook 3,
The amount of reflected light is imaged on the image sensor 19 for one line via the lens 18. The output of the image sensor 19 is input to the preprocessing unit 20, and the preprocessing unit 20 amplifies the output of the image sensor 19 and shapes the waveform. When the output is amplified and the waveform is shaped, the black-and-white judging section 21 judges black and white for each pixel in one line.

When the passbook 3 is conveyed for a predetermined distance, the control unit 16 stops the motor 24, cancels various settings of the black-and-white judging unit 21, and finishes the reading operation of the bar code 28. .

In step S2, the control unit 16 determines whether the bar code read for each line is a vertical bar code or a horizontal bar code, depending on the number and arrangement of pixels judged to be black. And judge simultaneously.

This determination method will be described below. Control unit 16
Is set to have a horizontal bar code when it is determined that a predetermined number or more of the pixels in one line are black, and it is determined to be absent when the number is less than the predetermined number. . When the vertical bar code 29 is read, it is determined that there is a predetermined number or more of black pixels in one line. As a result, when the bar code 29 is read, the control unit 16 determines that the horizontal bar code 30 is present.

Therefore, for example, the bar code 28 is a vertical bar.
In the case of code 29, 1 read by the image sensor 19
The line 16 is judged as a vertical bar code 29 by the control unit 16 based on the result of the black-and-white judgment unit 21, and the number of pixels of a predetermined number or more in one line is judged as black. −
It is also determined as the code 30.

Further, the bar code 28 is a horizontal bar code 30.
In the case of, one line read by the image sensor 19 is
Based on the result of the black-and-white determination unit 21, the control unit 16 controls the horizontal bar
It is judged as a do. Further, although not the vertical bar code 28, the vertical bar code 28 is also set to be judged, so that the vertical bar code is judged to be abnormal data.

In step S3, the control unit 16 determines in step S3.
The result determined in step 2 is stored in the storage unit 25 as vertical bar code data and horizontal bar code data every time one line is read. If the read bar code 28 is a vertical bar code 29, the mark value is stored in the vertical bar code data storage unit 25a of the storage unit 25 shown in FIG. -Code data storage unit 2
5b stores the presence or absence of black pixels in the line. On the other hand, when the read bar code 28 is the horizontal bar code 30, the horizontal bar code data storage unit 25b of the storage unit 25 stores whether or not there is a black pixel in the line. The vertical bar code data storage unit 25a stores abnormal data (whether or not there are black pixels in the line) as a vertical bar code.

In step S4, the control unit 16 causes the storage unit 25
Call the horizontal bar code data stored in. Then, the length (thickness C) of the horizontal bar code data in the direction orthogonal to the bar code reading direction is determined.

In step S5, the control unit 16 controls the horizontal bar cover.
If the horizontal bar code 30 is larger than a predetermined thickness, it is judged whether the width of the horizontal bar code 30 is larger than a predetermined thickness. The read bar code 28 is a vertical bar code 29. And step S6
If it is "No", it is judged to be a horizontal bar code,
Go to step S8.

In step S6, the control unit 16 causes the storage unit 25
Calls the vertical bar code data stored in.

In step S7, the control unit 16 controls the vertical bar cover.
The mark value is determined by the arrangement of data. Then, the page number of the vertical bar code 29 is analyzed based on the mark value.

When the process proceeds from step S5 to step S8, the control unit 16 analyzes in step S8 how many pages the horizontal bar code indicates by the arrangement of the horizontal bar code data. . And after that, it progresses to step S9.

In step S9, the control unit 16 determines whether or not the analyzed result is a normal number of pages. If it is determined that the number of pages is normal, the process ends and the next process is performed. In the case of "no", the process proceeds to step S10.

In step S10, the control unit 16 determines whether or not the retry process has been performed once, and if the result is "No", the retry process for rereading the page mark is performed again. Is driven to reversely rotate the pair of transport rollers 6 to transport the leading end portion 3a of the passbook 3 to a position below the image sensor 19. Then, the process returns to step S1 and retry processing is performed. When it is determined in step S9 that there is an abnormality even after the retry process, the process proceeds from step S10 to step S11.

In step S11, the control unit 16 determines that there is an error, drives the motor 24, reversely rotates the transport roller 6, and transports the passbook 3 to the insertion / ejection port 4. Then, the passbook 3 is returned to the customer, and the transaction ends.

Therefore, according to the above-mentioned embodiment, the vertical bar cover
Regardless of the code 29 or the horizontal bar code 30, the number of pages indicated by the bar code 28 can be analyzed by one bar code reading operation. before,
It is not necessary to input the direction of the bar code 28 printed on the passbook 3, while the passbook recording machine 1 judges the direction of the bar code 28, not the input to the passbook recording machine 1. Even in the case, the conventional two page identification operations are reduced to one.

In the present embodiment, the apparatus for reading the page mark of the passbook 3 has been described, but the present invention is not limited to the passbook 3 and may be a bar.
The present invention can be applied to an apparatus for reading the bar code 28 of a booklet-shaped medium in which the directions of the code 28 are mixed with the reading direction.

The bar code 28 is not limited to the page mark, but may be, for example, a mark for judging the front and back of a certificate,
A mark provided for the purpose of discriminating the type of medium may be used.
