Abstract

PURPOSE:To allow the title device to cope automatically with the deviation of the position of an original or a change in its size by modifying and outputting image information of a form sent from an image sensor in response to a size detection signal and a position detection signal sent from a boundary identifier. CONSTITUTION:The image sensor 1 reads image information of the form retained by a form retainer 12 optically. The boundary identifier 2 identifies a specific pattern and the form pattern of the original to generate the size detection signal representing the size of the form and the position detection signal representing the position of the form. An output controller 3 modifies and outputs the form image information sent from the image sensor in response to the size detection signal and the position detection signal sent from the boundary identifier 2. The modified image output is sent to a printer 4, where the result is printed out as a copy output. Thus, the copying is executed simply without notifying the position deviation of the original or its size.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a copying apparatus for copying images on paper.

BACKGROUND OF THE INVENTION In recent years, copying devices have become increasingly popular, but some are analog type, in which an optical image is projected onto an electronic development surface using a lens system, and others are analog type, in which an optical image is projected onto an electronic developing surface using a lens system, or a type in which an optical image is converted into an electrical signal by an optical image sensor. There is a so-called digital type that outputs to a printer.

Problems to be Solved by the Invention However, since all of the above-mentioned copying devices directly copy the original image, for example, if the position of the original is misaligned, the copy result may be misaligned, and when making reduced or enlarged copies, it is necessary to adjust the original size each time. It was necessary to specify the output size.

The present invention solves the above problem and provides a copying apparatus that can easily copy documents without being concerned about misalignment or size of the document.

Means for Solving the Problems In order to solve the above problems, the copying apparatus of the present invention includes a paper holder on which a specific image pattern is substantially imprinted and configured to suppress the back side of the surface to be copied of the paper. , an image sensor that reads the image information of the paper suppressed by the paper suppressor, and an image information G connected to the image sensor and transmitted from the image sensor to identify the specific image pattern included in the specific image pattern and other patterns. a boundary identification device that generates a size detection signal indicating the size of paper and a position detection signal indicating the position of the paper; and a size detection signal connected to the image sensor and the boundary identification device and transmitted from the boundary identification device. and an output control device that transforms and outputs paper image information transmitted from the image sensor in response to the position detection signal; and the transformed image information that is connected to the output control device and transmitted from the output control device. It consists of a printer that prints.

Effect of the Invention With the above-described configuration, the present invention allows normal copy output without being tilted even if the original is placed diagonally. Furthermore, since the copying apparatus of the present invention automatically determines the original size, when making enlarged/reduced copies, it is only necessary to specify the size of the output paper, and there is no need to specify the original size. effective.

Embodiment Hereinafter, an embodiment of the copying apparatus of the present invention will be described with reference to the drawings.

The first example shows an example of a pattern printed on the paper retainer 12. In order to explain the effect of the paper retainer of the present invention, this figure also shows a document set in a slightly tilted state. The difference from the original becomes clear electrically. Note that although a checkered pattern is shown in this embodiment, it is clear from the gist of the present invention that the specific pattern may be any pattern that is unlikely to appear on general manuscript paper.

FIG. 2 shows an embodiment of the invention without the paper holder. In Fig. 2, 1 is the sensor, 2 is the boundary identification device, and 3 is the output side? 1) Device, 4 is a printer, 5 is a specific pattern detector, 6 is a synthesizer, 7 is a paper pattern detector,
8 is a control signal generator, 9 is a memory, and 10 is a position change! , 1) is a size conversion device.

A specific pattern, such as a checkered pattern, for example, is substantially imprinted on the paper retainer 12 of FIG. 1 by a method such as printing. This pattern is on the side of the paper that is in contact with the back side of the side to be copied.

The image sensor 1 optically reads image information of the paper held down by the paper holder 12.

The boundary identification device 2 is connected to the image sensor 1 and receives image information transmitted from the image sensor 1.

This image information includes the specific pattern of the paper retainer 12 and the image information of the document, overlapping each other as shown in FIG. 1, for example. The boundary identification device 2 generates a size detection signal indicating the size of the paper and a position detection signal indicating the position of the paper by identifying the specific pattern and the paper pattern of the original.

The boundary identification device 2 includes a specific pattern detector 5 that detects a specific pattern, a paper pattern detector 7 that detects a pattern other than the specific pattern, and output signals of the specific pattern detector 5 and the paper pattern detector 7. The configuration may also include a synthesizer 6 that outputs a size detection signal and a position detection signal in response to the size detection signal and the position detection signal.

The output control device 3 is connected to the image sensor 1 and the boundary identification device 2. The output control device 3 transforms and outputs the paper image information transmitted from the image sensor in response to the size detection signal and the position detection signal transmitted from the boundary identification device 2.

This deformation operation includes deformations such as enlargement/reduction, rotation, etc. that fall within the scope of so-called linear transformation.

The modified image output output from the output control device 3 is transmitted to the printer 4 and printed as a copy output. The output control device 3 includes a memory 9 that temporarily stores image information, a control signal generator 8 that receives a size detection signal and a position detection signal, and generates a position conversion command signal and a size conversion command signal, and a memory 9. a position conversion device 10 connected to the control signal generation device 8 and configured to convert the position of image information in response to a position conversion command signal; and a position conversion device 10 connected to the control signal generation device 8 and configured to convert the position of image information in response to a position conversion command signal; The configuration may also include a size conversion device 1) that converts the size of image information.

Effects of the Invention As described above, the present invention is an effective device that fundamentally solves the difficulty of using conventional copying devices and can automatically respond to misalignment of originals and changes in size. be.
