Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an image processing system that reads a document with a scanner under the control of a host and outputs the document onto a sheet with a printer.
[0002]
[Prior art]
In a conventional image processing system in which a document is read by a scanner based on the control of the host and output onto a sheet by a printer, when the host instructs the scanner to read the document, as shown in FIGS. Then, the scanner starts reading from the original point (x, y) = (0, 0) of the document and transfers the read image data to the host. Then, as shown in FIGS. 7A and 7C, when the host transfers image data to the printer, the printer has an upper left corner of the paper so that non-image areas are formed at the upper, lower, left and right edges of the paper. Printing is started from a predetermined printing start time deviated from the corner, that is, the origin (x, y) = (0, 0) to the lower right by about several mm. This non-image area differs depending on the printer.
[0003]
[Problems to be solved by the invention]
By the way, in general, a copying machine is provided with non-image areas at the top, bottom, left, and right edges of a paper when copying an original image on paper, as shown in FIGS. A document image is not formed in this non-image area. Therefore, in the conventional image processing system, as shown in FIG. 8, the upper left corner of the original image cannot be output on the paper at the same position as the copying machine, and the position of the image on the original and the image on the paper are not There is a problem that the positions cannot be matched.
[0004]
An object of the present invention is to provide an image processing system capable of outputting an image so that the position of an image on a document matches the position of an image on a sheet.
[0005]
[Means for Solving the Problems]
In order to achieve the above object, according to the first means, the scanner reads a document based on the control of the host and transfers it to the host, and the printer transfers the image transferred from the host to the upper, lower, left and right edges of the sheet. In an image processing system that performs printing so that an area is formed, the scanner reads the entire surface of the document, stores the read data in a storage unit, and a reading start position on the document is read out from the storage unit. Control is performed so as to shift in correspondence with the non-image area .

DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the drawings. 1 is a block diagram showing an embodiment of an image processing system according to the present invention, FIG. 2 is a block diagram showing in detail the image processing system of FIG. 1, and FIG. 3 is an explanatory diagram showing a reading range by the first method, FIG. 4 is an explanatory diagram showing the reading range by the second method, FIG. 5 is an explanatory diagram showing the reading range by the third method, and FIG. 6 is an explanatory diagram showing the position of the output image according to the present invention.
[0010]
1 and 2, the host computer 1 and the image reading apparatus 2 are connected via a SCSI interface, a LAN, or the like. Then, the reading driver software 1a of the host computer 1 can instruct the image reading device 2 to read a document, and can take in the image data read by the image reading device 2. The host computer 1 and the printing device (printer) 3 are connected via a parallel interface or the like. When the print driver software 1b of the host computer 1 transfers the image data fetched from the image reading device 2 and its print instruction, the printer 3 converts the received image data into non-image areas at the top, bottom, left and right edges of the paper. As is formed, printing is started from a predetermined printing start time deviated from the upper left corner of the paper, that is, the origin (x, y) = (0, 0) by a few millimeters to the lower right. Although the printing start time differs depending on the model of the printer 3, it is assumed here that the right side and the lower side are shifted by 5 mm.
[0011]
The image reading apparatus 2 will be described in detail with reference to FIG. The document on the contact glass 11 is illuminated by the lamp 12 and the reflecting plate 13. The reflected light of the document is sequentially reflected by the first mirror 14, the second mirror 15, and the third mirror 16, imaged by the lens 17, and read by the CCD 18. The read signal is converted into digital image data by the A / D converter 19, and the image data is transferred to the host computer 1 via the image processing device 20, the memory 21, and the external input / output device 22.
[0012]
Here, the reading device 2 has the designated upper left reading start position and lower right reading end position (0 mm, 0 mm), respectively.
(210mm, 297mm)
In this case, the A4 document is read from the upper left corner to the lower right corner. The following two methods can be considered as a method for the reading device 2 to shift the reading start position. In the first method, the reading start time itself on the document is shifted. In this method, the CPU 23 reads the reading start position x in the main scanning direction by the CCD 18 and the reading start position y in the sub scanning direction by the lamp 12, the reflector 13, the first mirror 14, the second mirror 15, the third mirror 16, and the like. Control. In the second method, the reading start position is the upper left corner of the document, that is, (x, y) = (0, 0), but the read data is stored in the memory 21 and reading on the document is started when the memory is read. The CPU 23 controls so as to shift the time.
[0013]
Next, the reading start range will be described. As a first method, the user reads the original reading start position and the reading end position (5 mm, 5 mm) for the reading driver software 1a of the host computer 1, respectively.
(215mm, 302mm)
To start reading. When the reading driver software 1a instructs the reading start range and the reading start to the image reading apparatus 2, the upper end and the left end of the original are not read by an offset of 5 mm as shown in FIG. 3, and the right end and the lower end of the original are not read. Are read by an extra 5 mm, that is, a non-document area.
[0014]
As a second method, the user sets the reading start position and the reading end position of the document (5 mm, 5 mm), respectively.
(210mm, 297mm)
To start reading. When the reading driver software 1a instructs the reading start range and the reading start to the image reading apparatus 2, the upper end and the left end of the document are not read by an offset of 5 mm as shown in FIG. Is read.
[0015]
As a third method, the user sets the document reading start position and reading end position (5 mm, 5 mm), respectively.
(205mm, 292mm)
To start reading. When the reading driver software 1a instructs the reading start range and reading start to the image reading apparatus 2, the upper end, the left end, the right end and the lower end of the document cannot be read by an offset of 5 mm as shown in FIG.
[0016]
The image data read in this way is transferred to the printer 3 by the print driver software 1b of the host computer 1, and the printer 3 forms non-image areas at the top, bottom, left and right edges of the A4 size paper as shown in FIG. When printing is performed in this manner, the position of the image on the document matches the position of the image on the paper.
[0017]
【The invention's effect】
As described above, according to the first aspect of the present invention, the scanner reads the entire surface of the original, stores the read data in the storage means, and the reading start position on the original at the time of reading from the storage means is the non-reading position. Since control is performed so as to shift in accordance with the image area, it is possible to output so that the position of the image on the document and the position of the image on the paper coincide.
