Next, a printing process for the passbook N executed by the CPU 24 based on the control program stored in the ROM 25 will be described with reference to FIG. Passbook printer 1
First, the process waits until it is determined that the execution of the printing process by depressing the start key is declared (S1).

If it is determined in step S1 that the printing process is to be executed by depressing the start key (Y in S1), the transport rollers 6a, 6b, 6c, 6d, 6
e is rotated clockwise in FIG. 1 to drive the stepping motor 5, and the timer 28 drives the stepping motor 5 to start rotating.
Measurement is started (S2). Thereby, the transport roller 6
a, 6b, 6c, 6d, and 6e rotate clockwise in FIG. 1, and the passbook is conveyed from the insertion slot 3 side to the printing unit 7 side.

When it is determined that the driving time t1 measured by the timer 28 has become equal to or longer than the driving time T1 after the driving of the stepping motor 5 is started (Y in S3),
Driving time t after starting driving of the stepping motor 5
It is determined whether the leading end of the passbook N has been detected by determining whether or not the reading start sensor 13 has been turned off until it is determined that 1 has exceeded the driving time T1 (S4).
Here, the drive time T1 is defined as the end of the passbook N that is transported in the guide path 4 by the transport rollers 6a, 6b, 6c, 6d, and 6e by rotating the stepping motor 5 after the start key is pressed down. This is a time set in advance based on a time estimated to be required until the reading start sensor 13 is turned off when the section E crosses the optical axis of the reading start sensor 13.

In step S4, when it is determined that the reading start sensor 13 is turned off before the driving time t1 exceeds the driving time T1 after the driving of the stepping motor 5 is started (Y in S4), the reading is performed by the timer 28. Start sensor 13
Stepping motor 5 after it is determined that
The measurement of the driving time t2 is started (S5), and the process waits until it is determined whether or not the motor is driven by the driving pulse number X1 after the reading start sensor 13 is turned off (S6). here,
The number of drive pulses X1 means that the stepping motor 5 is used to convey the passbook by a distance corresponding to the margin from the end of each inner sheet P of the passbook to the portion where the page mark B, the ruled line L and the like are provided. The number of driving pulses.

On the other hand, if it is determined that the reading start sensor 13 has not been turned off until the drive time t1 exceeds the drive time T1 after the drive of the stepping motor 5 is started.
(N of S4), predetermined error processing is executed.

If it is determined in step S6 that the stepping motor 5 has been driven for X1 pulses since the reading start sensor 13 was turned off (Y in S6), the reading of the page by the CCD 12 is performed at intervals of T (ms). The number m (times) of readings by the CCD 12 at this time is stored (incremented) in the count area as needed (S7). Where T
The (ms) interval is a time set in advance according to the transport speed of the passbook N or the like.

In step S8, the process waits until it is determined that the CCD 12 has read the page mark B (N in S8).

(S11). Here, the read number information corresponds to the number of lines already printed based on the number m (times) of reading by the CCD 12 until the read line is determined to be an unprinted line. This is the number of drive pulses required to drive the stepping motor 5 in order to carry the passbook N by a distance.

Then, based on the correction data Y obtained in step S9 and the information on the number of readings obtained in step S11, the number of drive pulses X2 for determining the printing start position in the printing process described later is obtained (S12). . Here, the number of drive pulses X2 is a stepping distance for conveying the passbook by the number of printed lines including the displacement Y 'in addition to the considerable distance from the print sensor 14 to the print position on the platen 8. This is the number of drive pulses required when driving the motor 5.

If it is determined that the drive time t2 is longer than the drive time T2 (Y in S13), the drive time t2
It is determined whether or not the pass sensor N has been conveyed to the printing unit 7 by determining whether or not the print sensor 14 has been turned off before the drive time T2 has exceeded (S14). here,
When the stepping motor 5 is driven at intervals of a predetermined number of pulses, the driving time T2 is such that the passbook N conveyed in the guide path 4 crosses the optical axis of the reading start sensor 13 so that the reading start sensor 13 is turned off. After determining that the print sensor 14 has become
Is the time estimated to be required to turn off.

If it is determined in step S14 that the print sensor 14 has been turned off before the drive time t2 has become longer than the drive time T2 (Y in S14), it is determined that the print sensor 14 has been turned off. And then step S12
Waits until it is determined that the stepping motor 5 has been driven by the drive pulse number X2 obtained in (Y in S15).
(N in S15). Here, a function as a transport control unit is executed. As a result, when printing is started, the passbook is conveyed by the number of lines that have already been printed, including the shift amount Y ′ for each page. Can be printed in accordance with the ruled line.

If it is determined in step S15 that the print sensor 14 has been turned off and then the stepping motor 5 has been driven by the number of drive pulses X2 obtained in step S12 (Y in S15), the stepping is performed. Motor 5
Is turned off (S16), and a predetermined printing process is executed (S17).

The processing in step S17 is executed by printing out predetermined information in units of one line in accordance with the print data, and conveying each line by the conveying roller 6 every time one line is printed. Detailed description is omitted because it is a technology.

Here, the correction data Y corresponding to the page mark B is obtained from the correction data storage table, and the passbook N is transported to a position including the shift amount Y 'for each page according to the obtained correction data Y. Transport rollers 6a,
6b, 6c, 6d, and 6e are driven and controlled,
Before starting printing, the passbook N is transported by the number of printed lines including the shift amount Y ', and printing can be started from an accurate printing start position for each page. Thereby, printing can be performed at the correct printing position for each page.

Next, a second embodiment of the present invention will be described with reference to FIG. The same parts as those in the first embodiment are denoted by the same reference numerals, and the description is omitted.

Here, for example, if it is assumed that there is no deviation between the end E of the cover C and the end E 'of the middle sheet P with the passbook N opened, the reading by the CCD 12 is started. From the theoretical reading number M (times) until it is determined that the page mark B has been read, and the actual reading number m (times) from the start of reading by the CCD 12 to the determination that the page mark B has been read, They have the same value.

However, in practice, a gap occurs between the end E of the cover C and the end E 'of the inner sheet P when the passbook N is opened, so that the theoretical number of readings M (times) is Is different from the number of readings m (times).

In the passbook printer 1 according to the second embodiment,
In addition to a count area for temporarily storing the number of readings m (times) secured in the RAM 26, a theoretical value storage area (not shown) for storing the theoretical number of readings M (times) is secured in the ROM 25. However, this is different from the first embodiment.
In the second embodiment, the number of readings m (times) is used as reading position information.

FIG. 4 is a flowchart showing a printing process according to the second embodiment. The processing from step S21 to step S26 executes the same processing as the processing from step S1 to step S6 in FIG.

In step S28, the process waits until it is determined that the page mark B has been read by the CCD 12 (S2).
8N), when it is determined that the page mark B has been read (Y in S28), the CCD stored until the determination that the page mark B has been read with reference to the count area is made.
12, the number of readings m (times) is obtained, and the number of readings m

Here, the theoretical driving pulse number Xt (theoretical value) of the stepping motor 5 for transporting the passbook N by the distance corresponding to the distance from the end E of the cover C to the page mark B.
Is obtained based on the theoretical number of readings M (times) by the CCD 12 and the formula. Xt = X1 + V (pps) × T (ms) / 1000 × M

On the other hand, the number of readings m (times) stored in the count area is the actual number of readings counted from the start of reading by the CCD 12 until it is determined that there is a page mark B. For this reason, the actual number of drive pulses X3 for driving the stepping motor 5 to convey the passbook N by the distance corresponding to the distance from the end E 'of the inner sheet P to the page mark B is obtained by the equation. X3 = X1 + V (pps) × T (ms) / 1000 × m

According to the formula, the theoretical driving pulse number Xt (theoretical value) of the stepping motor 5 for transporting the passbook N by an amount corresponding to the distance from the end E of the cover C to the page mark B, and the inner paper P Between the actual driving pulse number X3 of the stepping motor 5 that conveys the passbook N by an amount corresponding to the distance from the end E 'of the first step to the page mark B, a deviation amount Y' corresponding to the expression is generated. I do. Y '= Xt-X3 ...

Incidentally, since the correction data Y is a value for offsetting the shift amount Y 'between the end E of the cover C and the end E' of the middle sheet P, Y 'shown in the equation is the correction data Y. Becomes equal to In other words, in step S29, the correction data Y is obtained by executing the arithmetic processing shown in the following formulas.

On the other hand, from step S30 to step S3
The processing up to 1 executes the same processing as the processing from step S10 to step S11 in FIG.

Then, based on the correction data Y obtained by the calculation in step S29 and the number of readings m (times) obtained in step S31, the number of driving pulses X4 for determining a printing start position in a printing process described later. (S3
2). Here, X4 is a value from the print sensor 14 to the platen 8
In addition to the equivalent distance to the print position above, the shift amount Y '
And the number of drive pulses required to drive the stepping motor 5 to convey the passbook N by the number of printed lines.

If it is determined that the drive time t2 is longer than the drive time T2 (Y in S33), the drive time t2
It is determined whether or not the print sensor 14 has been turned off before it is determined that the time has exceeded the drive time T2 (S34).

If it is determined in step S34 that the print sensor 14 has been turned off by the time the drive time t2 has become longer than the drive time T2 (Y in S34), it is determined that the print sensor 14 has been turned off. And then step S32
It waits until it is determined that the stepping motor 5 has been driven by the number of drive pulses X4 obtained in step (S35). Here, a function as a transport control unit is executed. Thus, when printing is started, the passbook N has been conveyed by the number of lines already printed, including the shift amount Y ', which differs for each printing process that occurs at the time of conveyance. Subsequent to the next line, the contents of the current transaction can be printed in accordance with the ruled line L.

On the other hand, if it is determined in step S34 that the print sensor 14 has not been turned off before it is determined that the drive time t2 has exceeded the drive time T2 (N in S34), a predetermined error process is executed. I do.

If it is determined in step S35 that the print sensor 14 has been turned off and the motor has been driven by the drive pulse number X4 obtained in step S32,
(Y in S35), the driving of the motor is stopped (S36), and a predetermined printing process is executed (S37). Since the correction data Y obtained in the second embodiment is calculated and obtained for each printing process, the transport rollers 6a, 6b, 6c, 6d, 6e
Even when the shift amount Y 'differs each time, such as when the inner sheet P is pushed back by the clamping force, the shift can be corrected each time and printing can be performed at a correct position.

Here, the correction data Y is acquired each time printing is performed by executing a predetermined calculation process. According to the acquired correction data Y, the passbook N is moved to a position including the shift amount Y 'for each page. The transport rollers 6a, 6
By controlling the driving of b, 6c, 6d and 6e, the passbook N is conveyed by the number of printed lines including the shift amount Y 'before printing starts, and accurate printing starts for each page. It becomes possible to start printing from the position. Accordingly, printing can always be performed at the correct printing position in accordance with the shift amount Y ′ generated when the passbook N is transported.
