Abstract

PURPOSE:To prevent unsatisfactory printing of a bar-code and prevent misreading from occurring, by reading a bar-code by a bar-code reader upon printing of the bar-code, and comparing bar-code data designated to be printed with the data of the bar-code actually printed. CONSTITUTION:A bar code 3 is read by a bar-code reader 2, and the data of the bar-code thus read is compared with bar-code data previously stored in a memory. When the two kinds of data being compared coincide with each other, the printed bar-code is determined as normal, and the process started with a step of storing bar-code data into the memory is repeated, or is finished. When the two kinds of data being compared do not coincide with each other or when the bar-code can not be read by the bar-code reader 2, the printed bar-code 3 is determined as unsatisfactory, and an abnormal condition processing is performed. Namely, the abnormal condition is reported to the operator by an erroneous message generated by an abnormal condition processing means in a controlling means 5, or by a sound generated by an alarm or the like, then printing by a printer 1 is stopped, and operation is finished.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a barcode printing printer having a function of verifying a printed barcode.

[Prior Art] Conventional barcode printing printers did not have a function to verify printed barcodes.

For this reason, printed barcodes are used without being inspected, or if they are inspected, they are inspected visually or manually using a barcode reader.

[Problems to be Solved] The conventional barcode printing printer described above does not have a verification function, so it has the disadvantage that it continues printing even if the barcode is incomplete.

Furthermore, in an ink ribbon type printer, when the ink is dark, the barcode part becomes thin, and when the ink is light, the black part becomes pale, but in either case, it passes the visual inspection by a human. For this reason, there is a problem that a barcode that cannot be recognized by the barcode reader is printed, resulting in a reading error.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a printer with a barcode printing verification function that can prevent printing of incomplete barcodes.

[Means for Solving Problems] In order to achieve the above object, the present invention provides a barcode printing printer that prints barcodes, a barcode reader that reads barcodes printed by this barcode printing printer, and the barcode printing printer. The barcode data that is instructed to be printed is compared with the barcode data read by the barcode reader, and if the two data do not match, an abnormality is notified and the printing is stopped. This is the configuration.

[Example] Hereinafter, an example of the present invention will be described based on FIGS. 1 and 2.

FIG. 1 is a schematic perspective view of the embodiment, and FIG. 2 is a flowchart.

! In Figure 11, 1 is a printer that prints barcodes, 2 is a barcode reader that reads barcodes printed by printer 1, 3 is a barcode printed by printer 1,
4 is paper on which the barcode 3 is printed. Reference numeral 5 denotes a control means that instructs the operation of the entire printer apparatus, and operates according to a predetermined procedure. A computer is used for this control means, and the printer l
It also serves as an abnormality processing means that compares the barcode data that is instructed to be printed with the barcode data read by the barcode reader 2, and when the two do not match, it notifies you of an abnormality and also sends a command to the printer l to stop printing. Function. 6 is a printer cable that connects the printer l and the control means 5, and 7 is a barcode reader cable that connects the barcode reader 2 and the control means 5.

The barcode reader 2 is fixed at a position where it can read the barcode 3 printed by the printer 1.

The control means 5 operates according to the flowchart shown in FIG.

The operation of the embodiment will be explained below with reference to flowcharts.

First, the printer 1 is instructed to print a barcode (5TI), then the data of the barcode instructed to be printed is stored in memory (Sr1). Determine whether printing is finished or not 5
T3), 'If there is a barcode printed, print the barcode with the printer 5T4), if there is not, a page break is performed (Sr5), and the paper is moved to a position where the barcode reader 2 can read the previously printed barcode 3. Send 4.

Next, the barcode reader 2 reads the barcode 3 (Sr1 or 5T7), and compares the read barcode data with the barcode data stored in the memory (Sr1 or 5T9). If the results match, it is a normal barcode, so either the edge reversal process is performed from the step (Sr1) of storing the barcode data in the memory (in the case of Sr1), or the process is terminated (in the case of Sr1).

If they do not match or cannot be read by the barcode reader 2, the barcode 3 is incomplete and abnormality processing (STIO) is performed, and an error message or an alarm (not shown) is sent by the abnormality processing means in the control means 5. The operator is notified of the abnormality by a sound from a device, etc., and the printer 1 stops printing and ends its operation.

It should be noted that the present invention is not limited to the above-mentioned embodiments.
Various modifications are possible within the scope of the invention.

[Effects of the Invention] As explained above, the present invention reads a barcode printed by a printer using a barcode reader at the time of printing, and compares the data of the barcode instructed to be printed with the data of the barcode actually printed. Comparison has the effect of preventing incomplete barcode printing and preventing reading errors from occurring.

Claims (1)

[Claims] A barcode printer that prints barcodes, a barcode reader that reads barcodes printed by this barcode printer, and barcode data that is instructed to be printed by the barcode printer and a barcode that is read by the barcode reader. A printer with a barcode printing verification function, characterized in that it is equipped with an abnormality processing means that compares the barcode data with code data and, if the two data do not match, notifies an abnormality and stops printing.
