DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for correcting a printing error in a passbook handling device, and more particularly to a method for correcting a printing error in a passbook handling device for correcting the printing position of a passbook using a dot impact type passbook printer for printing a passbook. About the method.

2. Description of the Related Art In a conventional apparatus for printing a passbook handled by a bank, an agricultural cooperative, or the like, there is a problem that printing cannot be performed at an accurate position due to the swelling of a middle sheet when the passbook is inserted into the apparatus.

An example of a conventional system for correcting the printing position of a passbook is described in Japanese Patent Application Laid-Open No. Hei 7-256970. The print misalignment correction device of the passbook printer described in this publication is a system that recognizes the length of an inspection medium, compares it with a theoretical length, and calculates a correction value.

A mark reading head mechanism, means for storing image data read by the mark reading head mechanism, and analysis of image data of actual measurement values of two reference lines at a predetermined interval printed on a test passbook. A control circuit for obtaining a correction value from the analysis result and the theoretical value is provided, and means for storing the correction value.

When the test passbook is read by the mark reading head mechanism during the shipping inspection of the apparatus, the length of two reference lines is measured, a correction value is calculated by comparison with the theoretical length, and the correction value is conveyed to the printing position. Correction.

[0006]

A first problem with the above-described conventional printing error correction method for a passbook handling device is that a passbook handling device which has been used for a long period of time has an inaccurate print position on the first line. May not be printed.

[0007] The reason for this is due to the influence of the deterioration of the transport rollers, the belts and gears that transmit the drive, the difference in the thickness of the inserted passbook, and the influence of the bulging of the inner paper when the passbook is inserted into the apparatus.

[0008] The second problem is that printing cannot be performed at an accurate position using only the correction value at the time of shipping inspection.

The reason for this is that the deviation of the printing position due to the deterioration of the rollers, belts and gears gradually increases with use of the apparatus. Also, the printing position shift due to the bulging of the inner paper is
This is because the shift width differs every time a medium is inserted depending on the page to be printed or the insertion method.

[0010]

According to the present invention, there is provided a method for correcting a printing error of a passbook handling apparatus, comprising: a scanner for recognizing a page mark printed on a passbook when handling a passbook having a page mark printed on each page; A memory storing the data read by the scanner, the type of page mark and the position of the page mark, a print head for printing the transaction result on the passbook, and a transport path for transporting the passbook to the scanner and the print head. Analyzes the difference between the theoretical value of the specification of the distance from the top of the passbook to the top of the page mark and the measured value of the data read by the scanner, and corrects the transfer of the passbook to the print position using the difference. It is constituted by doing.

[0011]

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of a method for correcting a printing error of a passbook handling apparatus according to the present invention.

Referring to FIG. 1, when a printing operation of a passbook or the like is performed, a host device 1 instructs a main CPU 2 of the method of correcting a printing error of the passbook handling device of the present invention to perform operations such as suction of a medium and printing. Put out. The main CPU 2 executes the operation request received from the host device 1 and transmits the execution result to the host device 1. The main CPU 2 has a scanner 3
Is connected to a memory 4 for storing the read image data and the print position of the page mark. Transfer CP
U5 is an interface (I / F) with the main CPU2.
After receiving an operation instruction for medium conveyance from the main CPU 2, the conveyance motor is controlled to convey the medium, and the execution result is transmitted to the main CPU 2.

FIG. 2 is a flow chart showing the operation of an embodiment of the method for correcting a printing error of the passbook handling apparatus according to the present invention shown in FIG. 2; The operation will be described with reference to an operation diagram showing the operation of the embodiment.

The host device 1 notifies the main CPU 2 of information on the type and position of the page mark of the passbook to be recognized. The main CPU 2 stores the received information in the memory 4 and transmits a completion notification to the host device 1 (step S1).

The host device 1 issues a passbook suction instruction to the main CPU 2 in order to print a passbook using the print head 8. The main CPU 2 issues a passbook transfer instruction to the transfer CPU 5. The transport CPU 5 operates the pulse motor 6 to transport the passbook in the suction direction. Main C during passbook transfer
The PU 2 monitors the sensor 7 and starts reading data with the scanner 3 when the leading end of the passbook reaches the sensor 7, and sequentially stores the read results in the memory 4 (Step S).
2).

When the entire page mark range has been read, the transport CPU 5 stops the pulse motor 6 and sends an end of transport to the main CPU 2. The main CPU 2 analyzes the image data stored in the memory 4 and recognizes the leading edge of the medium and the page mark (step S3). FIG. 4 is a diagram showing image data read by a scanner and a position on a specification according to an embodiment of a method for correcting a printing shift of the passbook handling apparatus of the present invention. FIG. 4A shows an example of an actually read image, in which the distance from the leading edge of the medium to the upper end of the page mark is X. FIG. 4B shows the position of the page mark of the passbook in the specification, and the distance Y from the top of the medium to the top of the page mark is stored in the memory. When there is an influence such as bulging of the middle paper, X and Y have different values. Therefore, if the difference between the position on the specification and the actually measured value is Z, Z = XY, and the value is used to carry out correction when transporting to the print position (step S4).

After the correction value calculation, the main CPU 2 requests the transport CPU 5 to transport the medium to the transport CPU 5 in order to transport the medium to the printing position. At this time, assuming that the theoretical number of steps for transporting to the printing position is A, the number B of steps actually transported is B = A + Z
(Step S5).

According to this operation, the medium can be conveyed to an appropriate printing position while considering the influence of swelling of the medium.

[0020]

As described above, the first effect of the method for correcting a printing error of the passbook handling apparatus of the present invention is that printing can always be performed at an appropriate position.

The reason is that the type and position of the passbook used from the host device are stored in the memory, the page mark position is compared with the memory contents from the leading edge of the medium calculated from the read image, the correction value is calculated, and the printing position is calculated. This is because the correction is made when the sheet is conveyed to.

The second effect is that the printing position can be corrected by always calculating an appropriate correction value even if there is an influence of the deterioration of the conveying roller and the belts and gears that transmit the driving roller.

The reason is that the correction value is automatically calculated each time a passbook is inserted.
