DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, an embodiment of a data collation printer and a print result collation method according to the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment in which the data collation printer according to the present invention is applied to a print data collation printer.

As shown in FIG. 1, the print data collation printer includes a print data processing unit 3 for creating print data, a print unit 1 for receiving the print data and actually printing the print data, and a print unit 1 for printing. An image reading unit 7 for reading the contents thus read out and an image recognizing unit 5 for recognizing data of the image reading unit 7 are provided. Further, as shown in FIG. 1, in the print data collation printer, each of the above components is of an integrated type.

The printing section 1 performs printing based on the print data output from the print data processing section 3.

The print data processing section 3 creates print data for printing, and outputs the print data to the print section 1 and the image recognition section 5.

The image reading section 7 reads the content printed by the printing section 1 and outputs the read result to the image recognition section 5 as print result data.

The image recognition unit 5 includes a print data processing unit 3
And the print result data output from the image reading unit 7 are input, and both data are collated. Further, in a certain case, the upper device is notified of the abnormality.

Next, an example of the operation of one embodiment of the print data collation printer according to the present invention shown in FIG. 1 will be described with reference to FIG. However, the flowchart shown in FIG. 2 shows a flowchart of an example of the operation of the data collation printer according to the present invention shown in FIG. 1 and also shows a flowchart of an embodiment of a print result collating method according to the present invention. is there. Therefore, FIG. 2 shows a flowchart of an example of the operation of the print result collation method according to the present invention and an example of the operation of the print data collation printer shown in FIG.

In this print data collation printer, first, a print pattern is created by the print data processing section 3 (step S).
1) The printed pattern is printed by the printing unit 1 (step S3).

Next, the printed pattern is read by the image reading section 7 (step S5), and the read pattern is recognized by the image recognition section 5 based on the printed pattern (step S7). The data is collated with the print pattern created by the processing unit 3 (step S9).

As a result of data collation, if the patterns match (Yes), the process ends normally. If the patterns do not match (No), the paper is returned to the printing unit 1 and abnormal ticket printing is performed (step S13). Then, an abnormality notification is made to the host device (step S15), and the operation is thereafter terminated.

Next, the print data collation printer shown in FIG. 1 will be described in more detail.

The print data collation printer shown in FIG. 1 may be a thermal type print data collation printer. And this thermal type print data collation printer,
As described above, the print data processing unit 3 that generates print data, the print unit 1 that receives the print data and actually performs thermal printing, and the image reading unit 7 that reads the content printed by the print unit 1 And an image recognition unit 5 for recognizing data of the image reading unit 7. In addition, each of the above-mentioned components takes an integral type.

Next, an example of the operation of the above-described thermal type print data collation printer and an embodiment of the print result collation method according to the present invention will be described in more detail with reference to FIG.

This thermal type print data collation printer is
First, a print pattern is created by the print data processing unit 3 based on the print code transferred from the host device (step S1).

Next, the printing section 1 prints the printing pattern in a thermosensitive manner (step S3), and the image reading section 7 reads the printing pattern (step S5).

Next, the image recognition unit 5 collates the print pattern created by the print data processing unit 3 with the print pattern read by the image reading unit 7 (step S).
9).

As a result of this collation, if the print patterns match (Yes), the process ends normally. If the print patterns do not match (No), the paper is returned to the print unit 1 and
An abnormal ticket is printed (step S13). At the same time, an abnormality is notified to the host device (step S15), and the operation is thereafter terminated.

Therefore, with the above-described configuration and operation, the data collation printer and the print result collation method according to one embodiment of the present invention check whether or not the print result is correctly printed, and confirms whether or not a cash voucher is used. If an erroneous print is made on an important print, invalidation can be performed to prevent the erroneous print from leaking.

However, the data collation printer and the print result collation method according to the present invention are not limited to the above-described embodiment. For example, as a printing mode, not only characters but also other printing modes such as patterns can be used. And
The data collation printer is not limited to an integrated type, and each function may be a distributed data collation printer in which positions are conceptually dispersed, and a printing method may also be used.
Other than the heat-sensitive method, other methods such as an ink-jet method can be used. Various modifications can be made without departing from the spirit of the present invention.
