BACKGROUND OF THE INVENTION
The present invention relates to a passbook row detection device comprising magnetic information reading means capable of reading magnetic information written in a passbook and optical reading means capable of optically reading print information written in each row of the passbook. .
[0002]
[Prior art]
Within one passbook, there are cases where the final print line is written as magnetic information depending on the type of transaction, and there are cases where it is not written.
[0003]
Here, when the last printed line is written as magnetic information, the line to start printing in this transaction is determined by matching the magnetic information with the final printed line based on the optical reading result.
[0004]
On the other hand, when the final print line is not written as magnetic information, the final print line is determined based only on the optical reading result by the optical reading unit, and the print start line is determined based on the final print line. Therefore, it is necessary to detect lines with higher accuracy.
[0005]
Here, since the passbook is printed using various passbook printers, the print density may be low. In such a case, if the last printed line is erroneously determined without being able to detect the numbers printed on the passbook, a fatal mistake that double printing on the printed line may occur. is there.
[0006]
In order to prevent such a serious error from occurring, it is conceivable to always perform optical reading with an optical reading means having high reading sensitivity. However, if the last printed line is written as magnetic information, if dust with a relatively high concentration is attached to the passbook, or if the show-through characters are relatively clear, such dust, etc. Will be optically read in the same manner as a normally printed number.
[0007]
An object of the present invention is to prevent optically reading dust, show-through characters, etc. adhering to the passbook when the final print line is written as magnetic information in the passbook depending on the type of transaction. Another object of the present invention is to provide a passbook line detection device capable of reliably preventing double printing when the last printed line is not written as magnetic information.
[0008]
[Means to solve the problem]
The present invention relates to a bankbook comprising magnetic information reading means capable of reading magnetic information written in a magnetic recording section of a bankbook, and optical reading means capable of optically reading print information written in each row of the bankbook. In the line detection device, the means for determining whether or not the information on the final print line is written in the magnetic recording part of the passbook, and the information on the final print line in the magnetic recording part based on the determination result by the determination means And a reading sensitivity adjusting means for increasing the reading sensitivity of the optical reading means when it is determined that the final print line information is written. Is.
[0009]
In such an invention, when the final print line is not written as magnetic information depending on the type of transaction, the reading sensitivity of the optical reading means is increased as compared with the case where the final print line is written. Even if the density of the displayed numbers is thin, it can be read optically reliably. Therefore, it is possible to accurately detect the final print line and completely prevent double printing.
[0010]
When the final print line is written as magnetic information, the double printing can be prevented and the reading sensitivity of the optical reading means is not increased. Even when there is high dust or characters on the back side of the passbook are copied, it is possible to reliably prevent the dust from being optically read.
[0011]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described with reference to the drawings.
[0012]
As shown in FIGS. 1 to 3, the basic configuration of the bankbook row detection device is the same as that of the conventional example. However, read sensitivity adjustment means (71, 72) are provided so that the magnetic recording unit of the bankbook can be used as a final unit. When the information of the print line is not written, the reading sensitivity of the optical reading unit 10 is increased as compared with the case where it is written.
[0013]
First, the control means 70 shown in FIG. 1 is a means for driving and controlling the entire passbook row detection device, such as a CPU 71, a program ROM 72, a program RAM 73, an image RAM 74, a keyboard 75, an input / output device (I / O) 76, and the like. It is composed of The input / output device 76 is connected to the printing unit 1, the optical reading unit 10 (CCD 11), the magnetic information reading unit 20, and the like.
[0014]
Here, the printing unit 1 includes a print head 2 for printing on a passbook, a print head driver 2D, a print head moving motor 7M for moving the print head 2, and a motor driver 7D. .
[0015]
The optical reading means 10 includes a CCD 11 and a CCD controller 11D, and is formed so that each row of the passbooks can be optically read.
[0016]
The magnetic information reading means 20 includes a magnetic head 21 and a magnetic driver 21D, and is formed so as to be able to read and write magnetic information such as a final print line on a magnetic recording part (magnetic stripe) of a bankbook.
[0017]
The read sensitivity adjusting means, which is a characteristic part of the present invention, is more effective when the information of the final print line is not written in the magnetic recording part of the passbook depending on the type of transaction than when it is written. ) To increase the reading sensitivity. In this embodiment, the reading sensitivity adjustment means includes a program ROM 72 that stores a reading sensitivity adjustment program, a CPU 71, and a reading sensitivity setting device (not shown), and is formed so that the reading sensitivity of the optical reading means 10 can be adjusted. ing.
[0018]
That is, the reading sensitivity is adjusted by changing the setting of the threshold Vth for the output voltage (V1, V2) of the CCD 11 shown in FIG. Here, if the threshold Vth is lowered (if the slice level for detecting printing is set to a higher density), the reading sensitivity is lowered, and if it is increased (if the slice level is set to a lower density), the reading sensitivity is reduced. Goes up.
[0019]
Next, the operation of this embodiment will be described based on the flowchart shown in FIG.
[0020]
When the final print line is not written as magnetic information in the passbook depending on the type of transaction (NO in ST10), the reading sensitivity of the optical reading means 10 (11) is increased as compared with the case where the final print line is written. . That is, after the slice level is set to a low density (ST12), each row of the passbook is read by the optical reading means 10 (11). Therefore, even if the density of numbers printed on each line of the passbook is thin, it can be reliably read optically, and as a result, the final printed line can be detected accurately and double printing can be completely prevented.
[0021]
When the last printed line is written as magnetic information (YES in ST10), after the slice level is set to the higher density (ST11), each line of the passbook is read by the optical reading means 10 (11). Read. Therefore, for example, even when there is dust with high density in the line before the final print line or characters on the back side of the passbook are copied, it is possible to reliably prevent the dust from being optically read. it can.
[0022]
Thus, according to this embodiment, the reading sensitivity of the optical reading means 10 (11) is more effective when the last print line information is not written in the magnetic recording part of the passbook depending on the type of transaction. Since the reading sensitivity adjustment means (71, 72) is provided to increase the printing speed, the final printing line is accurately detected and double printing is completely prevented when the final printing line is not written as magnetic information. be able to. In addition, in the case of a transaction book in which the last printed line is written as magnetic information, not only can the above-mentioned double printing be prevented, but for example, there is high-concentration dust on the line before the last printed line, Even when characters on the back side are projected, it is possible to reliably prevent dust and the like from being optically read.
[0023]
【The invention's effect】
According to the present invention, the means for determining whether or not the information of the last print line is written in the magnetic recording part of the passbook according to the type of transaction, and the final result in the magnetic recording part based on the determination result by the determination means. Since it is provided with a reading sensitivity adjusting means for increasing the reading sensitivity of the optical reading means when it is determined that the information of the print line is not written, it is determined depending on the type of transaction. When the printed line is written as magnetic information in the passbook, it is possible to prevent the dust and show-through characters attached to the passbook from being optically read, and the final printed line is written as magnetic information. If not, double printing can be surely prevented.
