Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is obtained by reading a page mark written on a medium when an automatic transaction device or the like installed in a financial institution reads or writes a medium such as a passbook having several pages. The present invention relates to a page mark reading device for analyzing image data and determining whether or not it is a target page.

[0002]

2. Description of the Related Art Usually, in an automatic transaction device, when a transaction is carried out on a medium such as a passbook, the page mark given to each page of the medium is read and the image data obtained by the reading is analyzed, It is determined whether or not the opened page is the target page. Below, referring to the drawings,
The page mark reading and the storage state of its image data will be described.

FIGS. 4 and 5 are diagrams for explaining the operation of the page mark reading mechanism. In this page mark reading mechanism, the page mark reader 2 is arranged on the traveling system 1, the pass roller 4 is conveyed by the conveying roller 3 and positioned with respect to the page mark reader 2, and is attached to each page of the pass book 4. The page mark 5 that is printed is read. That is, in this page mark reading mechanism, first, when a control pulse (not shown) generates a drive pulse, a pulse motor (not shown) is driven. The driving force of the pulse motor is transmitted to the carrying roller 3 to rotate the carrying roller 3. Due to the rotation of the transport roller 3, the passbook 4 travels on the travel system 1. Then, the passbook 4 is run from the state shown in FIG. 4 to the state shown in FIG. 5, during which the page mark reader 2 reads the page mark 5 and stores it in a memory (not shown).

FIG. 6 is an explanatory diagram of page marks. The application range X1 of the page mark 5 is determined as a medium standard determined for each user and each passbook, and is given with a certain distance X2 from the tip of the passbook 4. Then, as described above, the page mark 5 is read by the page mark reader 2. At the reading start position, the image data in a wider range is read by providing a margin before and after the application range X1 of the page mark 5. There is. That is, in the figure, the distance X3 from the tip of the passbook 4
The image data including the page mark 5 is read within the reading range X4 by starting the reading from the position.

[0005]

When the page mark is read and stored in the memory as described above, logically,
As shown in FIG. 7, the read image data is stored from the analysis start address. However, in reality, due to manufacturing errors in the diameter of the transport roller for transporting the passbook, errors in the mounting position of the page mark reader that reads the page mark, errors in the printing position of the page mark, etc. The page mark may be misaligned and may not be recognized correctly. That is, the storage address of the image data varies from the analysis start address, and as shown in FIG. 8, the image data is stored with a distance of X5. In such a shifted state, the image data is not correctly analyzed and the page mark cannot be recognized.

For this reason, when installing the automatic transaction device or the like, the maintenance personnel or the like corrects the deviation. That is, as shown in FIG. 9, correction is performed by shifting the analysis start address to the storage address of the image data,
The above error is absorbed to enable correct analysis.
The correction is repeated until the page mark is read at any time while changing the correction value for shifting the analysis start address, the read result is confirmed, and the reading is correctly performed.

Therefore, conventionally, a person such as a maintenance worker has to make correction setting of the analysis start address until the reading result is correct, which causes a problem of burdening the maintenance worker.
There was a problem that the correction setting took time. Further, even if the correction value is set so that the reading result is correct, there is a slight deviation between the analysis start address corrected by the correction value and the storage address of the image data. It was not possible to find the correction value to make it disappear. Therefore, there is a problem that the accuracy of analysis of image data is lowered.

[0008]

SUMMARY OF THE INVENTION Therefore, according to the present invention, a registering unit for registering target page data of a target page mark in advance, an analysis start address is corrected according to a predetermined correction value, and the corrected analysis is performed. An analysis unit that recognizes the page mark by analyzing a predetermined analysis range of the image data from the start address and acquires the page data, and a comparison unit that compares the page data acquired by this analysis unit with the target page data at any time, When the comparison result of this comparison unit matches, it has an appropriate correction value storage unit that stores the correction value at the time of match, and during operation, corrects the analysis start address with the correction value of the appropriate correction value storage unit, The page mark reading device is designed to analyze the image data from the corrected analysis start address.

[0009]

With this configuration, the target page data of the target page mark is registered in the registration unit in advance, the analysis start address is corrected according to a predetermined correction value, and the image is obtained from the corrected analysis start address. If the specified analysis range of the data is analyzed, the page mark is recognized, the page data is acquired, and the acquired page data and the target page data are compared at any time and match, the correction value at the time of matching is appropriate. The correction start value is stored in the correction value storage unit, the analysis start address is corrected by the correction value in the proper correction value storage unit, and the image data can be analyzed from the corrected analysis start address.

[0010]

An embodiment of the present invention will be described below. FIG.
FIG. 3 is a block diagram of an image data analysis start position correction device. In the figure, reference numeral 2 is a page mark reader, which has been described in the prior art, and which optically reads a page mark.

A page mark image data storage unit 6 stores image data read by the page mark reader 2. An analysis unit 7 analyzes the image data stored in the page mark image data storage unit 6 to obtain page data corresponding to the page mark. A page data registration means 8 is means for pre-registering target page data corresponding to the page mark to be read.

Reference numeral 9 denotes a registration unit for registering the target page data in advance by the page data registration means 8.
Reference numeral 10 denotes a comparison unit that compares the page data analyzed and obtained by the analysis unit 7 with the page data registered in the registration unit 9, and the following minimum correction storage unit 11 and maximum correction storage unit 12 are provided. And the comparison result is sent to the proper correction processing unit 13.

The minimum correction storage unit 11 sets a minimum correction value when the comparison unit 10 determines that the two match. The maximum correction storage unit 12 sets the maximum correction value when the comparison unit 10 determines that the two match.
The proper correction processing unit 13 obtains an intermediate value between the minimum correction value and the maximum correction value output from the minimum correction storage unit 11 and the maximum correction storage unit 12, and, for example,
It is calculated as ((maximum correction value + minimum correction value) / 2).

Here, the maximum correction value is a value in the positive direction of the storage address of the image data, and indicates the maximum value that gives a correct reading result. In addition, the minimum correction value is a value in the negative direction of the storage address of the image data, and indicates the minimum value that gives a correct reading result. A correction value storage unit 14 stores the intermediate value obtained by the appropriate correction processing unit 13 as an appropriate correction value, and the analysis start address is corrected by the correction value stored here.

Next, a method of correcting the image data analysis start position of the page mark will be described with reference to the drawings. FIG. 2 is a flowchart, and FIG. 3 is an explanatory diagram of correction of the image data analysis start position. In the following description, the minimum correctable correction value is fixed, the maximum correctable correction value is changed from a predetermined value, and the maximum correction value and the minimum correction value are searched. That is, a maximum correction value that is an appropriate analysis result is searched while reducing the value from a predetermined initial value, and when the maximum correction value is determined, an appropriate analysis result is obtained while reducing the value from the maximum correction value. The minimum correction value is searched. Note that the search is not limited to the maximum correction value and the minimum correction value,
For example, when searching for the minimum correction value and the maximum correction value while increasing the value from the predetermined initial value, or when searching for the maximum correction value by decreasing the value from the predetermined initial value and increasing the value from the predetermined initial value and performing the minimum correction The value may be searched for. S1: As described in the related art with reference to FIG. 4, when the maintenance staff or the like installs the automatic transaction device or the like, the passbook 4 on the traveling system 1 is used.
The page mark of the passbook is read by the page mark reader 2 and stored in the page mark image data storage unit 6. At the time of this reading, the target page data of the target page mark is registered in advance in the registration section 9 by the page data registration means 8 shown in FIG. S2: When analyzing the image data, the maintenance personnel or the like sets the maximum correction value of the settable correction peculiar to the page mark reading mechanism as the initial value of the analysis correction value in the analysis correction storage unit (not shown) of the analysis unit 7. . S3: The analysis unit 7 obtains the analysis start address based on the analysis correction value and the storage address of the image data. That is, the analysis start value is obtained by adding the analysis correction value to the start address of the storage address of the image data. S4: The analysis unit 7 analyzes the storage address of the image data stored in the page mark image data storage unit 6 from the analysis start address obtained in S3 in the same manner as the conventional one, and the analysis result is compared with the comparison unit 10 Output to. S5: The comparison unit 10 compares the analysis result output from the analysis unit 7 with the image data registered in the registration unit 9 to determine whether the two match. If they are equal and match, the process proceeds to S6. If they are not equal and does not match, the process proceeds to S9. S6: The comparison unit 10 determines whether or not the maximum correction value has already been set in the maximum correction storage unit 12. The determination is equivalent to whether or not the match in S5 is the first time, and if it is the first time, the maximum correction value is not set, so the process proceeds to S7. If it is not the first time, the maximum correction value has been set, so the process proceeds to S8. S7: The comparison unit 10 sets the analysis correction value at the time of matching as the maximum correction value in the maximum correction storage unit 12. S8: The comparison unit 10 sets the analysis correction value at the time of matching as the minimum correction value in the minimum correction storage unit 11. S9: Decrement the analysis correction value in the analysis correction storage unit (not shown) of the analysis unit 7. S10: It is judged whether or not the analysis correction value in the analysis correction storage unit (not shown) of the analysis unit 7 becomes smaller than the settable minimum correction value, and when it becomes smaller, analysis is performed while shifting the analysis range for all correction values. Is finished, so S1
The processing is moved to 0, and the comparison unit 10 sets the appropriate correction processing unit 1
A comparison end control signal is sent to 3. If it has not become smaller, the analysis has not been completed.
Transfer processing to. S11: The appropriateness correction processing unit 13 uses the maximum correction storage unit 1
An appropriate correction value is obtained from the maximum correction value of 1 and the minimum correction value of the minimum correction storage unit 12. For example, an intermediate value is obtained by a calculation formula ((maximum correction value + minimum correction value) / 2), and the value is set as an appropriate correction value. S12: The appropriate correction processing unit 13 stores the obtained appropriate correction value in the correction value storage unit 14 and ends the process, and corrects the analysis start address with the appropriate correction value.

In the above embodiment, the page mark is read in order to obtain the appropriate correction value. However, the page mark may use the medium such as the passbook as it is, but separately from this. A medium dedicated to the correction operation may be prepared, and the correction operation may be performed on the medium. In the above-mentioned embodiment, by automatically changing the analysis correction value for the read image data, analysis is performed while shifting the analysis start position, and the analysis result is a value registered in advance, and the range is a correct analysis result. Was checked to find an appropriate correction value. In particular, the intermediate value can be set as an appropriate correction value.
