Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention has an optical reading means capable of optically reading each row of passbooks, and the area of a black dot in a row read by the optical reading means is larger than a reference area. The present invention relates to a line detection device that determines that there is printing on the line.

[0002]

2. Description of the Related Art In a bankbook printer such as an ATM, it is absolutely not allowed to perform printing in a place where printing is performed when writing bankbooks. Therefore, an optical reading unit (not shown) capable of optically reading each line of the passbook is provided, and the presence or absence of printing is determined for each line from the first line to the last line of the passbook.

That is, as shown in FIGS. 4 and 5, the area of a black dot (for example, the number "1") is obtained from the data of the row read by the optical reading means (ST20), and the area is determined as the reference area. If it is larger than the size (YE in ST21)
In S), it is determined that there is printing (ST22), otherwise (NO in ST21), it is determined that there is no printing (ST23).
doing. Here, the area of the black dot ("1")
As shown in FIG. 4 (B), the vertical dimension (V1) of the black dot
And the horizontal dimension (H1) are represented by the corresponding number of dots, and a numerical value obtained by multiplying the two numbers of dots.

[0004]

By the way, in the above-described line detecting device, for example, as shown in FIG.
The number ("2") may be printed over two lines (second and third lines). In such a case, the number ("2")
May not be detected, or a printed line may be erroneously detected.

[0005] In order to prevent the above-mentioned undetection or the like from occurring, the reference area for judging the presence or absence of the above-described printing may be reduced. It is easy to detect and it is difficult to find the final print line accurately.

SUMMARY OF THE INVENTION An object of the present invention is to provide a line detecting device capable of quickly and accurately detecting the last printed line of a passbook.

[0007]

According to the present invention, there is provided an optical reading means capable of optically reading each row of a passbook or the like, and the area of the black dot of the row read by the optical reading means is larger than a reference area. In some cases, in the line detection device that determines that there is printing on the line, if the area of the black dot of the line read by the optical reading unit is smaller than the reference area, the black dot exists over the adjacent line. First determining means for determining whether or not a black dot exists across adjacent rows, and dot total area calculating means for calculating a total area of the black dots based on read data of both rows when it is determined that the black dot exists across adjacent rows. If the calculated total area of the black dots is smaller than the reference area, it is determined that there is no printing, and if the calculated total area is equal to or more than the reference area that is equal to or larger than the reference area, it is determined that there is printing in the line where the center of the total area is located. The second judgment to judge Characterized by providing a stage.

In this invention, if the area of the black dot in one line of the passbook is smaller than the reference area and the black dot exists over adjacent lines, the black dot is determined based on the read data of both lines. The total area of the dots is calculated. If the calculated total area is smaller than the reference area, it is determined that there is no printing. If the calculated total area is equal to or larger than the reference area, it is determined that the line where the center of the total area is located has printing.

Therefore, since the reference area does not need to be set particularly small, it is possible to prevent dust or the like adhering to the passbook from being erroneously detected as print information, and to accurately detect numbers and the like printed over two lines. . as a result,
The last printed line can be detected quickly and accurately.

The passbooks inserted from the insertion slot 1A of the main body case 1 are transported rightward in FIG. Then, when the passbooks reach the magnetic recording reading section, the magnetic stripe is read by the magnetic head 21. Thereafter, the numbers and the like printed on specific portions of each row of the passbooks are optically read by the optical reading means 2. The read data is stored in the image RAM 74.

In this way, if the area of the black dot (for example, the number "2" shown in FIGS. 4A and 4B) of the row read by the optical reading means 2 is smaller than the reference area, It is determined whether or not exists over adjacent rows (2, 3 rows) (ST10, 11).

+ V3)) is calculated.

Here, "H" indicates the horizontal direction and "V" indicates the vertical direction. The numerical value after “H” and “V” indicates the line number. When the calculated total area of the black dots is smaller than the reference area (NO in ST14), it is determined that there is no printing (ST17), and when the total area is equal to or larger than the reference area (YES in ST14), the total area is determined. It is determined that there is printing on the line where the center is located (ST15). Here, the row where the center of the total area is located is defined as the row where the center of the total area is located by comparing the values of V2 and V3 with the larger value (S
T16).

Therefore, since the reference area does not need to be set particularly small, erroneous detection of dust or the like as print information can be prevented, and numbers and the like printed over two lines can be accurately detected.
