Abstract

PURPOSE:To prevent printing on a printing sheet erroneously beforehand by identifying whether it is a predetermined beforehand printing or not in advance prior to a printing operation. CONSTITUTION:Before the output of an information processor is printed by a recorder 2, a sensor 5 reads a barcode 9 on a beforehand printing sheet 1a, and transmits its read signal to a recognition unit 6. The unit 6 recognizes the type of the beforehand printing sheet on the basis of the signal, and transmits a recognition signal to a controller 7. The controller 7 compares by a comparator this recognition signal with a sheet type designation signal fed from the processor through a line 10. If the comparison result coincides, the controller 7 generates a signal for operating the recorder 2, and the recorder 2 prints the output data of the processor on the beforehand printing sheet. If the result does not coincide, the controller 7 transmits a signal to a display panel 8, and visually displays the type of the beforehand printing sheet by number or the like.

Description

Detailed Description of the Invention [Field of Industrial Application] The present invention relates to a printing device for printing output data of information processing ￥A＠ of a computer, etc. The present invention relates to a printing device that prints on pre-printed paper.

[Prior Art] Conventionally, in this type of printing device, many types of forms such as forms are printed in advance, and many types of pre-printed forms are created to print computer output data. In this case, the operator selects the pre-printed paper suitable for the output data and sets it in the printing device.

[Problems to be Solved by the Invention] In the conventional marking device described above, since the operator identifies the pre-printed paper by himself/herself, it is possible that the pre-printed paper differs from the pre-printed paper due to an operator error or mistake. This method has the disadvantage that printing is often performed on paper.

SUMMARY OF THE INVENTION An object of the present invention is to provide a printing device equipped with a paper identification function that does not print on any paper other than a predetermined pre-printed paper.

[Additional Means for Solving the Problems] In order to achieve the above object, the printing device of the present invention includes a sensor that reads paper identification information printed in advance at a predetermined position on preprinted paper, and a It has a recognition section that recognizes the type of the pre-printed paper based on the output, and a control section that controls the printing operation based on the output of the recognition section.

[Function] The recognition unit recognizes the type of pre-printed paper set in the printing device, and if the pre-printed paper is a predetermined one, the control unit operates the printing device, and if the other pre-printed paper is used, the control unit operates the printing device. Department does not operate the printing device.

[Example] Next, the present invention will be described in detail with reference to the drawings.

FIG. 1 is a schematic diagram of a printing apparatus according to an embodiment of the present invention. The printing device includes a recording section 2 that prints the output of an information processing device (not shown) such as a computer onto the paper 1a from the paper stack 1, a fixing section 3 that fixes the printed information on the paper 1a, and a printer that prints the printed information on the paper 1a. The stacker section 4 stores sheets of paper.

As shown in FIG. 2, the paper 1a is a pre-printed paper such as a form on which the base is printed in advance.

In the present invention, paper identification information such as a number representing the type of pre-printed paper is printed in the form of a barcode 9, for example, on the pre-printed paper 1a at a suitable place, for example, in the upper left corner, at the time of pre-printing. .

The printing device further includes a sensor 5 that reads the barcode 9 on the pre-print K (11a) immediately in front of the recording unit 2.The printer also recognizes the type of the pre-print paper based on the read signal from the sensor 5. A recognition unit 6 that performs the process, a control unit 7 that has a built-in appropriate comparison circuit that compares the recognition signal from the recognition unit 6 with a paper type designation signal from an information processing device such as a computer, and a signal from the v control unit 7. , and a display panel 8 that displays the type of pre-printed paper necessary for printing.

Next, the operation of the marking device according to this embodiment will be explained. Before the output of the information processing device is printed by the recording unit 2,
The sensor 5 reads the barcode 9 on the pre-printed paper 1a and sends the read signal to the recognition unit 6. The recognition unit 6 is
Based on the signal, the type of pre-printed paper is recognized and a recognition signal is sent to IIJ 12 section 7. The Lubrication control section 7 compares this recognition signal with a paper type designation signal sent via the line 10 from the information processing device using a comparison circuit. If the comparison results match, the control section 7 issues a signal to activate the recording section 2, and the recording section 2 prints the output data of the information processing device on the pre-printed paper. If the comparison results do not match, the control unit 7 sends a signal indicating the type of pre-printed paper required for printing to the display panel 8, and the display panel 8 visually displays the type of pre-printed paper necessary for printing using a number or the like. indicate.

Therefore, the operator can set the desired pre-printed paper prior to printing based on this display.

[Effects of the Invention] As explained above, the present invention prevents printing on the wrong pre-printed paper by identifying in advance whether or not it is a predetermined pre-printed paper before the printing operation. effective.
