Abstract
Abstract An automatic engraving system for automatically engraving the lateral contour of a person's face on one surface of a medal (4) includes two industrial television cameras (12a, 12b) for three-dimensionally measuring the lateral contour of the person's face by using light beam or laser light beam, a computor (2) for determining the lateral contour of the person's face by processing the dimensional data derived from measurements and at least one three-dimensional cutting machine (3) for engraving on the medal (4) the lateral contour of the person's face based on the processed date derived from the computor (2).

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
125 words
A system for automatically engraving medals each having the contour of a person's face as seen in the lateral direction on one surface thereof, comprising: three-dimensional contour measuring means for three-dimensionally measuring the lateral contour of the person's face by using light beam or laser light beam, a computer for processing the dimensional data derived from said three-dimensional contour measuring means to determine the lateral contour of the person's face, at least one three-dimensional cutting machine for engraving the lateral contour of the person's face on one surface of a metal as a raw material based on the data derived from said computer, and monitoring means for locating the center point of the person in correct alignment with the center line of said monitoring means.
Claim 2
Independent Claim
125 words
A system for automatically engraving medals each having the contour of a person's face as seen in the lateral direction on one surface thereof, comprising: three-dimensional contour measuring means for three-dimensionally measuring the lateral contour of the person's face by using light beam or laser light beam, a computer for processing the dimensional data derived from said three-dimensional contour measuring means to determine the lateral contour of the person's face, at least one three-dimensional cutting machine for engraving the lateral contour of the person's face on one surface of a metal as a raw material based on the data derived from said computer, and monitoring means for locating the center point of the person in correct alignment with the center line of said monitoring means.
Claim 3
Dependent Claim
64 words
The system as claimed in claim 1, wherein the lateral contour of the person's face is determined by sequentially measuring a width, a height and a thickness of the lateral contour of the person's face at a certain actual point on the latter and sequentially processing the data derived from said measurement in said computor by using a light beam or laser light beam.
Claim 4
Independent Claim
180 words
A system for automatically engraving medals each having the contour of a person's face as seen in the lateral direction on one surface thereof, comprising: three-dimensional contour measuring means for three-dimensionally measuring the lateral contour of the person's face by using light beam or laser light beam, a computer for processing the dimensional data derived from said three-dimensional contour measuring means to determine the lateral contour of the person's face, at least one three-dimensional cutting machine for engraving the lateral contour of the person's face on one surface of a metal as a raw material based on the data derived from said computer, and wherein said three-dimensional contour measuring means comprises two industrial television cameras each disposed at a position offset from the lateral contour of the person's face by a predetermined angle and two charge coupled devices electrically coupled to said two industrial television cameras, each of said two charge coupled devices including a monitor screen on which the lateral contour of the person's face is displayed and a number of lattice points being arranged on said monitor screen.
Claim 5
Independent Claim
180 words
A system for automatically engraving medals each having the contour of a person's face as seen in the lateral direction on one surface thereof, comprising: three-dimensional contour measuring means for three-dimensionally measuring the lateral contour of the person's face by using light beam or laser light beam, a computer for processing the dimensional data derived from said three-dimensional contour measuring means to determine the lateral contour of the person's face, at least one three-dimensional cutting machine for engraving the lateral contour of the person's face on one surface of a metal as a raw material based on the data derived from said computer, and wherein said three-dimensional contour measuring means comprises two industrial television cameras each disposed at a position offset from the lateral contour of the person's face by a predetermined angle and two charge coupled devices electrically coupled to said two industrial television cameras, each of said two charge coupled devices including a monitor screen on which the lateral contour of the person's face is displayed and a number of lattice points being arranged on said monitor screen.
Claim 6
Dependent Claim
107 words
The system as claimed in claim 3, wherein each width, each height and each thickness of the lateral contour of the person's face at each actual point are determined based on an angle defined by said actual point on the lateral contour of the person's face relative to the corresponding lattice point on the screen of one charge coupled device electrically coupled to one of the industrial television cameras and an angle defined by an actual point on said lateral contour of the person's face relative to the corresponding lattice point on the screen of other charge coupled device electrically coupled to other industrial television camera, respectively.
Claim 7
Dependent Claim
62 words
The system as claimed in claim 2, wherein said industrial television cameras are vertically displaced relative to the chair for the person and vice versa to sequentially determine said width, said height and said thickness at said actual point on the lateral contour of the person's face at all the lattice points on the screen of each of the charge coupled devices.
