Abstract

PROBLEM TO BE SOLVED: To improve operationality and reliability of a printing apparatus by inputting image data from a memory to judge a page number on the basis of contents of a bar code and judging an inclined state of a printing medium on the basis of a position of the bar code to control printing action. SOLUTION: A printing medium 1 comprises a notebook, which is formed by binding a plurality of printing sheets, like a bankbook, and a page mark 2 indicative of a page number is put on the respective printing sheets. The printing medium 1 is transferred in a direction of an arrow A and the page mark 2 is read by an image sensor 3 to permit data read to be stored by a memory 4. Image data stored is fed to a CPU 5 to be analyzed, so that a page number is judged based on contents of a bar code, and an inclined state (inclination angle θ) of the printing medium 1 is judged from a position of the bar code. A printing unit corrects the printing action according to the inclination angle θ to precisely perform printing on a printing column (columns) provided on the printing medium 1.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention reads a page mark composed of a bar code provided on a print medium that closes a plurality of print pages, such as a bankbook used in a financial institution. The present invention relates to a page mark reading device for determining the degree of skew of a print medium.

[0002]

2. Description of the Related Art A printing apparatus that uses a print medium, such as a bankbook used in a financial institution, in which a plurality of print pages are closed to form one book, is a bar code for indicating the page number on the print medium. The page mark configured is provided, and the page mark is read to determine the number of the printed page.Besides this page mark reading means, the presence or absence of skew in the print medium is determined. Sensor is provided.

[0003]

The above-described conventional skew check means for a print medium simply determines the presence or absence of skew, and when there is skew, the operation of the printing apparatus is performed. It is necessary to stop the printing and reload the print medium, and therefore the operation is troublesome.

SUMMARY OF THE INVENTION A page mark reading device of the present invention is an image sensor which is provided in a conveyance path for conveying a print medium and reads a page mark constituted by a bar code provided on the print medium as image data. When,
A memory for storing the image data from the image sensor, inputting the image data from the memory to determine a page number from the content of the barcode, and a skew angle of the print medium from the position of the barcode. And a control unit that corrects the printing operation in the printing unit according to the inclination angle and controls so that the printing is correctly performed in the printing field provided on the printing medium.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of the present invention, and FIG. 2 is a plan view showing the relationship between the print medium and the image sensor of the embodiment shown in FIG.

In FIG. 1, the print medium 1 is one in which a plurality of print pages are closed to form one book like a bankbook.
Each printed page has a page mark 2 to indicate the page number.
Is provided. For this page mark 2, a bar code similar to the bar code widely used for product management is adopted.

As shown in FIG. 2, the print medium 1 is guided along one edge of the conveying path 6 and conveyed in the direction of arrow A, and the page mark 2 is provided in the middle of the conveying path 6. Read by the image sensor 3.

The data read by the image sensor 3 is sent to and stored in the memory 4, as shown in FIG. The image sensor 3 reads the page mark 2 as image data, that is, the entire fixed area in which the page mark 2 is described as a graphic, and accordingly, the memory 4
The content stored in is the figure of the entire page mark 2. Therefore, when the print medium 1 is normally conveyed (when it is conveyed without skew), the left end of the barcode is parallel to the left side of the storage area of the memory 4, as indicated by reference numeral 4a. However, when the print medium 1 is conveyed obliquely, the left end of the barcode is inclined (inclination angle θ) with respect to the left side of the storage area of the memory 4, as indicated by reference numeral 4b.

The image data stored in the memory 4 is
It is sent to the control unit (CPU) 5 and analyzed, and the page number is determined from the content of the barcode, and the skewed state (tilt angle θ) of the print medium 1 is determined from the position of the barcode. Tilt angle θ determined by the control unit (CPU) 5
Is sent to a printing unit (not shown), and the printing unit corrects the printing operation according to the inclination angle θ, and correctly prints on the printing column provided on the printing medium 1. Therefore, even if the print medium 1 skews, it is not necessary to stop the operation of the printing device and reload the print medium 1, and correct printing can be performed in that state.

[0011]

As described above, the page mark reading device of the present invention stores an image sensor for reading the page mark provided on each print page of a print medium as image data and a page mark read by the image sensor. And a control unit that inputs image data from the memory, determines the page number from the barcode content, and determines the skewed state of the print medium from the barcode position to control the printing operation. Even if the print medium skews, there is no need to stop the operation of the print device and reload the print medium, and there is an effect that correct printing can be performed as it is. There is an effect that operability can be improved.
