However, if the phase of this pulse motor itself is disturbed even temporarily, even though the passbook's position is accurately detected by the detection sensor, there will be a transport error between the sensor's position and the passbook's printing unit. This could cause the print position on the passbook to be misaligned and be set, resulting in defective printing.

(C) Purpose of the Invention Therefore, it is an object of the present invention to provide a passbook printing device that can print while accurately correcting the misalignment of the printing position.

(d) Summary of the Invention This invention provides a passbook transport path on the front side of the passbook printing section.
Set a reference point for measurement and set a certain distance I to this reference point.
The number of conveyance pulses of the passbook conveyed between Ii is counted, this counted value is compared with the reference conveyance pulse number corresponding to the distance from the reference point to the printing part, and a correction value is calculated. It is characterized in that it is a passbook printing section d that adds to the reference number of transport pulses to control the transport of the passbook.

(E) Effects of the Invention According to the present invention, the conveyance state of the passbook is detected by counting the number of conveyance pulses during a certain distance that the passbook has been conveyed to the measurement reference point set in the front stage of the printing section. By comparing this number of conveyance pulses with the standard number of conveyance pulses set from the reference point to the printing section, the correction value of the pulse motor required to accurately position the passbook at the printing position can be calculated. The calculated passbook transport l with this correction value taken into account
By ti, the passbook is set at the proper printing position.

Therefore, regardless of the phase disturbance of the pulse motor, the bankbook can be accurately aligned with the printing position, and extremely accurate printing without printing deviation can be performed.

Among these, the first passbook detection sensor S1 is set as the reference point K for measurement with respect to the printing unit 15, and the set distance on the 114th stage side is set between both UN sensors S1 and 82 on the front stage side of the conveyance path with this reference point K as the center. Then set it to 1 and find the distance between this! The number of transport pulses of the passbook 12 passing through IL1 is detected and counted by both sensors S1 and S2. Then, the conveyance state of the passbook is determined based on the actually measured count value.

On the other hand, the distance between the second bankbook detection sensor S2 serving as a reference point and the printing section 15 on the subsequent stage side is set as a downstream side set distance IL2, and the reference conveyance pulse number during this downstream side set distance L2, By comparing the above-mentioned count value, the second pulse motor 2 necessary to accurately position the passbook 12 at the printing position is determined.
