The form paper 10 is set on a paper feed roller 20 and is sequentially conveyed to a front surface printing device 30 and a back surface printing device 40 by a drive device (not shown), and after printing is completed, it is wound up on a winding roller 50.

The front side printing device 30 includes a printing unit 31 that prints on the front side of the form paper 10 based on credit information transferred from the print control unit 70, and a mark that reads print timing marks recorded in advance on the form paper 10. A sensor 32 is provided. When the printing of the credit information on each unit form is completed, the printing unit 31 records an identification code corresponding to the printed credit information at a predetermined position on the surface of the unit form.

The back side printing device 40 includes a printing unit 41 that prints on the back side of the form paper 10 based on the credit information transferred from the print control unit 70, similar to the printing unit 31 described above.

The identification code reading unit 60 reads the identification code detected by the identification code detection unit 42 and sends it to the print control unit 70.
Notify.

The print control unit 70 determines the credit information to be printed on the front or back side of the unit form in consideration of the amount of credit information for each customer, and prints each piece of credit information in the same order on the front side printing device 30 and the back side, respectively. Transfer to the printing device 40. However, since the credit information is printed on the front side and then on the back side, the timing of transferring the credit information is predetermined in consideration of the time lag and the conveyance timing of the form paper 10.

Regarding this conveyance timing, the mark sensor 32 provided in the front stage of the printing section 31 of the front surface printing device 30
and a mark sensor 43 provided upstream of the printing section 41 of the back printing device 40 count the printing timing marks on the form paper 10, and after the printing section 31 prints the front side, the counted number of the printing timing marks is calculated. Accordingly, settings are made to print on the back side of a predetermined page. The printing section 3
Since the form paper conveyance distance between 1 and the printing unit 41 does not change once it is set, printing is always performed at the same timing by performing printing every predetermined count of print timing marks. Furthermore, since the distance between the mark sensor 43, the identification code detection section 42, and the printing section 41 is also constant, the timing of detection of the identification code before printing by the printing section 41 can also be set.

The print control unit 70 also controls the back side printing device 4.
Before printing with 0, the identification code reading section 60
It is checked whether the identification code read by the device matches the identification code indicating the credit information to be printed on the back side, and if they match, the credit information is printed on the back side printing device 4.
Transfer to 0. On the other hand, if the identification codes do not match, it is assumed that an abnormality such as a change in the transfer timing of the credit information and the transport timing of the form 10 has occurred, and an alarm device (not shown) is activated.

Next, the operation of this embodiment will be explained.

First, as an initial setting (step 91),
A roll of unprinted form paper 10 is set on the paper feed roller 20, and the leading edge of the form paper 10 is passed through the front side printing device 30 and the back side printing device 40 and then placed on the winding roller 50.
Attach it to the machine and make it ready for transportation.

At this time, the deviation between the front-side printing device 30 and the back-side printing device 40 of the form paper 10, that is, the number of unit forms between the printing units 31 and 41, is checked, and the number of unit forms and the conveyance of the form paper 10 are determined. The timing of transferring credit information to the front-side printing device 30 and the back-side printing device 40 is set in consideration of the speed.

[0029] Thereafter, the printing operation is started.

When the conveyance operation of the form paper 10 is started (step 92), the credit information is transferred to the front surface printing device 30 by the print control section 70 (step 93).
. This credit information is transferred in a predetermined order until there is no more credit information to be printed on the front side for the same customer (step 94). When printing on the front side of the first unit form is completed, the print control unit 70 sends an identification code indicating the printed credit information to the front side printing device 3.
0 and instructs recording of the identification code (step 95).

According to this instruction, the identification code is recorded at a predetermined position on the front surface of the unit form in the front surface printing device 30.

Thereafter, when the printing operation progresses and the unit form reaches the back side printing device 40, the identification code recorded on the front side of the unit form is detected by the identification code detection section 42. The detected identification code is read by the identification code reading section 60 and notified to the print control section 70 (step 96).

[0033] When the identification code is notified, the print control unit 7
0, the identification code indicating the credit information to be printed on the back side of the unit form and the identification code reading section 6
Check whether it matches the identification code notified from 0 (
Step 97), only if they match, transfer the credit information to be printed to the back printing device 40 (
Step 98). If the identification codes do not match, it is determined that an abnormality has occurred, and an alarm is activated to notify that fact (step 100). When the identification codes match and all the credit information to be printed on the back side of the same customer is transferred to the back side printing device 40, and the back side printing device 40 prints on the back side of the unit form (step 99).
), the credit information of the same customer is printed on both the front and back sides of the unit form, and the unit form is sequentially wound onto the winding roller 50.

In the above-described embodiment, an example was explained in which an identification code is recorded on the front side when printing is performed on the front side, but when printing is performed on the back side, the identification code may also be recorded on the back side. In this case, when the printing of the credit information on both the front and back sides is completed, the identification code will be recorded on both the front and back sides. And the back printing device 40
At the latter stage, a detection unit is provided to detect the identification codes recorded on both the front and back sides, and the two identification codes detected by the detection unit are read and checked again to see if they match. As a result, the accuracy of printing operations can be improved.

It is also conceivable that the identification code is not recorded on the form paper when printing the credit information.

In this case, a different form number is recorded in advance on both the front and back sides of each unit form, and the form number is used as a code for identifying credit information. First, when printing on the surface of the unit form, as shown in FIG.
, the form number is read at the front stage (or the latter stage may be used) of the surface printing device 30 and the form number is printed on the front side.The form number corresponds to a customer code predetermined for each customer as an information code for the credit information to be printed (printed). memorize it.

Thereafter, when printing the back side of the unit form, as shown in FIG. 1, the back side printing device 40 reads the form number on the back side, and reads the form number and the customer code of the credit information to be printed on the back side. It is checked whether the combination matches the combination of the front form number and customer code stored when printing on the front side, and if they match, printing is performed.

The form number recorded on the unit form may be a continuous number, as long as it is different for each unit form.

[0039] Furthermore, this form number can be similarly used even if it is recorded only on either the front side or the back side. In this case, when printing is performed by the surface printing device 30 of FIG. 1, the form number of the unit form is read and stored in correspondence with the customer code of the printed credit information. Then, the back printing device 40 in FIG.
When printing, the document number is read again, the customer code corresponding to the read document number is extracted from the stored customer code, and the customer code and the customer code of the credit information to be printed on the back are combined with the customer code. If they match, printing should be performed.

[0040]

As explained above, according to the form paper of the present invention, since the identification code is recorded on the front or back side, the identification code can be used to confirm the printed information. It becomes possible to print only print information related to the back side.

Furthermore, according to the printing method of the present invention, when printing on the other side of the form paper, the print information previously printed on one side and the print information to be printed on the other side match. Since it is checked whether or not the document is printed, it is possible to reliably print the relevant print information on the front and back sides of the form paper. In particular, in the case of the printing method according to claim 5, after printing on each side of the form paper is completed, it is checked whether the identification codes recorded on each side of the form match or not, so the reliability of the printing operation is improved. At the same time, it becomes possible to respond quickly when an abnormality occurs.
