The image system 1 includes an image reading device 2, an image processing device 3 of a copying machine, an image output device 4, a printer controller / image processing device 5, and a fax unit 6. Reference numeral 7 denotes a network.

  First, the image reading apparatus will be described. FIG. 4 is a diagram for explaining the image reading apparatus 2. As shown in FIG. 2, the image reading apparatus 2 places the document 18 on the transparent platen glass 14 so that the document surface is in the glass direction, and prevents the document 18 from floating with respect to the platen glass 14. The document 18 is pressed by the pressing device 15.

  In addition, some automatic document feeders are provided in place of the document pressing device 15 so that images can be input automatically and efficiently. However, in this device, a certain size is necessary for a document. It is difficult to use for a manuscript that should not be damaged or has a high image quality like a photograph.

  A document 18 placed on the platen glass 14 is illuminated by a light source 22 based on a power source from a power source 21 and is imaged by a CCD (Charge Coupled Device) sensor 25 or the like via an optical system such as a mirror 23 and a lens 24. Scanned, converted into an electrical signal, and output to the image processing device 3

  Next, the image processing apparatus 3 in the copying machine will be described. FIG. 5 is a diagram for explaining image processing in the copying machine. The electrical signal obtained by the image reading device 2 is subjected to A / D conversion for digital image processing, and is passed to the copier image processing device 3 as an image signal in the RGB color space.

The input-side color correction processing unit 31 converts an image signal in the RGB color space into L * a * B * which is a uniform color space, and performs color correction depending on the image input device / device.

  The character / photo separation processing unit 32 determines whether the input image is a character or a photograph in the plane based on the corrected L * a * B * image signal, separates the image, and switches the processing parameter thereafter. . In general, where it is determined to be a character, it is processed so that the edge reproduction that is important in the character / line drawing is good, and where it is determined to be a photo, the gradation that is important in the photo / picture, Processing is performed so that the graininess is good.

  By turning on a predetermined switch, the document holding area 516 is connected to the static electricity generating means 517 including the DC power supply, so that the document holding area 516 can be charged with static electricity. In this state, the document 18 can be held by bringing the document close to the document holding area 516.

  According to the sixth embodiment, since static electricity is generated in the document holding area 516 by the static electricity generating means 517, the document 18 can be held in the document holding area 516 while adjusting the positional deviation of the document. Thereby, it is possible to prevent the positional deviation of the document.

  Next, a seventh embodiment will be described. FIG. 16A is a perspective view of the image reading apparatus 601 according to the seventh embodiment, and FIG. 16B is a view for explaining the suction mechanism of the document pressing apparatus 615 of the document reading apparatus 601.

  In FIG. 16, reference numeral 601 denotes an image reading device, 12 denotes a case, 14 denotes a platen glass glass, 615 denotes an original holding device, 616 denotes an original holding area, 617 denotes an air intake hole, 619 denotes an air suction device, and 620 denotes a pipe. ing. About the location demonstrated in the said Example, the same code | symbol is attached | subjected and the description is abbreviate | omitted. The document pressing device 615 can hold the document in the document holding area 616 by air suction.

  The document holding area 616 is an area for holding the document 18 by air suction. A large number of air intake holes 617 are formed in the document holding area 616. As shown in the enlarged view of Y1 in FIG. 16A, the document holding area 616 has a large number of intake holes 617 formed therein. As shown in FIG. 16B, the intake hole 617 is formed so as to penetrate the space 618 in the document pressing device 615. An air suction machine 619 is connected to the space 618 via a pipe 620.

  The air suction device 619 corresponds to an air suction unit, and sucks air in the space 618 through the pipe 620. The air suction device 619 can be operated by operating a predetermined switch (not shown), for example.

  When air is sucked by the suction suction device 619, air is sucked from the suction hole 617. At this time, the original 18 can be held at a predetermined position in the original holding area 616 by bringing the original 18 closer to the original holding area 616.

  According to the seventh embodiment, since air is sucked by the air suction device 619 from the suction hole 617 provided in the document holding area 616, the document 18 is moved to the document holding area 616 while adjusting the positional deviation of the document. Can be held. Thereby, it is possible to prevent the positional deviation of the document.

  Although the preferred embodiment of the present invention has been described in detail above, the present invention is not limited to the specific embodiment, and various modifications are possible within the scope of the gist of the present invention described in the claims.・ Change is possible. For example, FIG. 10 shows a linear reference mark 64, but the present invention is not limited to this, and the reference mark is not limited to a linear one as long as it can detect a displacement. Any of them may be used. In the example shown in FIG. 10, the reference mark 64 is provided on the document holder 16, but the reference mark may be provided on the document pressing device.
