Description

Detailed Description of the Invention <Technical Field> The present invention uses a sensor to read an image on an image forming surface provided with a reference line for starting reading, and based on the reference line data included in the read image information, In an image reading device that corrects deviations in information and prints corrected image information, image information including a reference line read by a sensor is stored in a memory, and after correcting deviations in the image information stored in the memory, the image is printed. The present invention relates to an image reading device that can reproduce only a necessary image by converting reference line data of information into white data and printing based on the converted image information.

<Conventional technology> Continuous images (text, drawings, etc.) using a sensor
When I try to read the image and print the image,
Particularly when the sensor is small, there has been a problem in that the reproduced print data differs from the original image due to a shift in the reading start position.

For example, when trying to read image "A" by moving the sensor twice as shown in Figure 7, the sensor position for the first reading is set to 12a, and the sensor position for the second reading is set to 12b. If the first and second reading start positions are different as shown in 13a and 13b, the content printed by the first reading and the content printed by the second reading may be misaligned, as described in the 8th article. become.

In order to prevent this deviation, an apparatus has been developed that provides a pseudo reference line during reading and performs deviation correction using the reference line. That is, as described in the 9th article, the reference line 14 is provided, and the sensor is connected to the reference line 1.
After detecting 4, the image is read. As a result, the reading start position 15 is
Match on the th time. However, since the reference line is also read, as in the 10th issue, the reference line was to be printed in addition to the image "A".

<Object of the Invention> In view of the above circumstances, the present invention reads an image on an image forming surface provided with a reference line for starting reading with a sensor, and based on the reference line data included in the read image information, In an image reading device that corrects deviations in image information and prints the corrected image information, image information including a reference line read by a sensor is memorized, and after correcting deviations in the image information stored in the memory, To provide an image reading device capable of reproducing original image data by converting reference line data of image information into white data and printing based on the converted image information.

<Example> Hereinafter, the configuration of the present invention will be described with reference to the drawings.

FIG. 1 shows an image reading operation using an image reading device according to the present invention.
In order to read the paper surface information 2 formed on the paper surface 1, a transparent reference line plate 4 on which a reference line 3 is marked is placed on the paper surface 1.

Then, the operator passes the sensor 5 of the image reading device over the reference line 3 and then over the page information 2.

That is, as shown in FIG. 2, a reference line 3 is set on the page information 2, and the sensor 5 is moved on the page. Since the sensor 5 cannot read all of the page information 2 in one reading, the reading operation is repeated twice. The position of the sensor 5 in the first reading is represented by 5a, and the position of the sensor 5 in the second reading is represented by 5b. In any reading, the sensor 5 is always moved so as to read the reference line 3.

After reading, only the page information 2 is printed without printing the reference line 3, as shown in FIG.

FIG. 4 is a system block diagram of an image reading device according to an embodiment of the present invention, and in the figure, 5 represents the sensor. The sensor 5 specifically consists of a CCD sensor.

Further, 7 is a movement detector, and the sensor 5
And the movement detector 7 constitutes a sensor unit 8.

The operator holds the sensor unit 8 and reads an image of a desired area on the paper.

Each time the sensor unit 8 moves by a predetermined amount, the movement detector 7 outputs a signal. When the signal is output from the movement detector 7, the LSI
(Processing unit) 9 stores the data read by the sensor 5 in a storage element (random access memory RAM).
etc.) Write in 10. Then, at the same time as the reading is completed, the LSI 9 reads out the stored contents of the storage element 10 and prints them out using the printer 11.

When the image shown in FIG. 2 is read, the page information 2 and the reference line 3 are read at the same time, and the read image information is stored in the storage element 10 as shown in FIG. In FIG. 5, "1" indicates that an image exists, and "0" indicates that no image exists, and in this embodiment, "0" is "white data".

In the same figure, data “1” (indicated by B in the figure) located on the left side of broken line 1 exists due to the existence of continuous data “1” from the top to the bottom of the paper (indicated by B in the figure).
This data corresponds to the reference line 3, and it can be seen that the data "1" on the right side of the broken line 1 (indicated by A in the diagram) corresponds to the data on the page information 2, and the data on the left side of the broken line 1 Convert data “1” to “0”. That is, after converting to "white data", the printer 11 prints out the data.

As a result of the above conversion, the data stored in the memory element 10 becomes as shown in FIG. 6, so that only the original paper surface information 2 is printed, and the reference line 3 is not printed.

<Effects> As described above, according to the present invention, a reference line is provided,
The sensor reads the image on the forming surface along with the reference line, corrects the misalignment of the read image information based on the reference line data, and then converts the reference line data in memory to white data and prints it. It becomes possible to print only the image on the surface and not print the reference line.

Therefore, not only can the image read on the forming surface be accurately reproduced, but also only the necessary image can be reproduced, so it is expected that the range of use of the image reading device will be expanded.
