Method and system for patching original and extracting original-trimming data in scanner

Claim 1

A method for patching an original and extracting original-trimming data in a scanner, which comprises: mounting a layout sheet on a digitizer, determining by the digitizer location data of a trimming frame for at least one pattern on the layout sheet and location data of a rectangular region circumscribing the trimming frame and corresponding to an area to be trimmed, storing these location data in a memory device, and reading out the location data of the trimming frame for the pattern from the memory device and displaying trimming lines for the pattern on a monitor; picking up an original by means of a pick-up device, adjusting the angle, location and pick-up magnification of the original so as to display a desired duplicate portion of the original in such a way that the desired duplicate portion is fit in the trimming frame for the pattern; calculating the location data of the rectangular region, which corresponds to the trimmed area of the original, on the original from the location data of the rectangular region corresponding to the trimmed area of the original and the pick-up magnification, shifting the original by means of an original-holding plate from the pick-up location thereof while maintaining the angle and patching the original on an input drum of the scanner or an original-patching sheet mounted on the input drum, and calculating the location data of the rectangular region, which corresponds to the trimmed area of the original, on the input drum from the distance of displacement of the original-holding plate and the location data of the rectangular region of the original, which region corresponds to the trimmed area of the original, on the original.

Claim 2

A method for patching an original and extracting original-trimming data in a scanner, which comprises: mounting a layout sheet on a digitizer, determining by the digitizer location data of a trimming frame for at least one pattern on the layout sheet and location data of a rectangular region circumscribing the trimming frame and corresponding to an area to be trimmed, storing these location data in a memory device, and reading out the location data of the trimming frame for the pattern from the memory device and displaying trimming lines for the pattern on a monitor; picking up an original by means of a pick-up device, adjusting the angle, location and pick-up magnification of the original so as to display a desired duplicate portion of the original in such a way that the desired duplicate portion is fit in the trimming frame for the pattern; calculating the location data of the rectangular region, which corresponds to the trimmed area of the original, on the original from the location data of the rectangular region corresponding to the trimmed area of the original and the pick-up magnification, shifting the original by means of an original-holding plate from the pick-up location thereof while maintaining the angle and patching the original on an input drum of the scanner or an original-patching sheet mounted on the input drum, and calculating the location data of the rectangular region, which corresponds to the trimmed area of the original, on the input drum from the distance of displacement of the original-holding plate and the location data of the rectangular region of the original, which region corresponds to the trimmed area of the original, on the original.

Claim 3

A system for patching an original and extracting original-trimming data in a scanner, which comprises: a digitizer for determining location data of a trimming frame for at least one pattern on a layout sheet, location data of a rectangular region circumscribing the trimming frame and corresponding to an area to be trimmed and data specifying the location of the rectangular region corresponding to the area to be trimmed; a memory device for storing these location data; an original-holding plate for holding an original at a desired angle and position; a pick-up device for picking up the original with a desired magnification; a monitor for displaying a desired duplicate portion of the image of the original, which image has been picked up by the pick-up device, in the trimming frame for the pattern which frame has been read out from the memory device; an original-shifting device for shifting the original from the pick-up position by the pick-up device to an input drum of the scanner or an original-patching sheet mounted on the input drum while maintaining the desired angle; and means for detecting the distance of displacement of the original-shifting device.

Claim 4

A system for patching an original and extracting original-trimming data in a scanner, which comprises: a digitizer for determining location data of a trimming frame for at least one pattern on a layout sheet, location data of a rectangular region circumscribing the trimming frame and corresponding to an area to be trimmed and data specifying the location of the rectangular region corresponding to the area to be trimmed; a memory device for storing these location data; an original-holding plate for holding an original at a desired angle and position; a pick-up device for picking up the original with a desired magnification; a monitor for displaying a desired duplicate portion of the image of the original, which image has been picked up by the pick-up device, in the trimming frame for the pattern which frame has been read out from the memory device; an original-shifting device for shifting the original from the pick-up position by the pick-up device to an input drum of the scanner or an original-patching sheet mounted on the input drum while maintaining the desired angle; and means for detecting the distance of displacement of the original-shifting device.
