Original position confirming means for duplicating apparatus

Claim 2

In a reproducing apparatus in which an original to be reproduced is placed on a transparent platen overlying a projection aperture and illuminated with an image reflecting light source to project the information pattern through an optical system onto the surface of a photosensitive material, apparatus for aiding an operator in accurately positioning the original to be reproduced in registration with the aperture and transparent platen comprising, auxiliary illumination means for illuminating at least a portion of the original to be reproduced during placement of the original onto said transparent platen, optical means operatively associated with said auxiliary illumination means for directing at least a portion of the illumination from said auxiliary illumination means through said aperture onto the surface of the original to be reproduced to illuminate the original to be reproduced in relation to said aperture, and means for energizing said auxiliary illumination means independent of the energization of said image reflecting light source to permit an operator to obtain a view of the original to be reproduced and accurately position the original in registration with the aperture and said platen before making a reproduction of the original image.

Claim 3

In a reproducing apparatus in which an original to be reproduced is placed on a transparent platen overlying a projection aperture and illuminated with an image reflecting light source to project the information pattern through an optical system onto the surface of a photosensitive material, apparatus for aiding an operator in accurately positioning the original to be reproduced in registration with the aperture and transparent platen comprising, an auxiliary light source for illuminating at least a portion of the original to be reproduced during placement of the original onto said transparent platen, optical means operatively associated with said auxiliary light source for directing at least a portion of the illumination from said auxiliary light source through said aperture onto the surface of the original to be reproduced to illuminate the original to be reproduced in relation to said aperture, and means for selectively energizing said auxiliary light source independent of the energization of said image reflecting light source to permit an operator to view an of the original to be reproduced and accurately position the original in registration with aperture and said platen before making a reproduction of the original image.

Claim 4

In a reproducing apparatus in which an original to be reproduced is placed on a transparent platen overlying a projection aperture and illuminated with an image reflecting light source to project the information pattern through an optical system onto the surface of a photosensitive material, apparatus for aiding an operator in accurately positioning the original to be reproduced in registration with the aperture and transparent platen comprising, an auxiliary light source for illuminating at least a portion of the original to be reproduced during placement of the original onto said transparent platen, optical means operatively associated with said auxiliary light source for directing at least a portion of the illumination from said auxiliary light source through said aperture onto the surface of the original to be reproduced to illuminate the original to be reproduced in relation to said aperture, and means for selectively energizing said auxiliary light source independent of the energization of said image reflecting light source to permit an operator to view an of the original to be reproduced and accurately position the original in registration with aperture and said platen before making a reproduction of the original image.

Claim 5

In a reproducing apparatus in which an original to be reproduced is placed on a transparent platen overlying a projection aperture and illuminated with an image reflecting light source to project the information pattern through an optical system onto the surface of a photosensitive material, apparatus for aiding an operator in accurately positioning the original image to be reproduced in registration with the aperture and transparent platen comprising, an auxiliary light source supported within said reproducing apparatus in substantially non-interfering relationship with the image projecting optical system of said reproducing apparatus for illuminating at least a portion of the original to be reproduced during placement of the original onto said transparent platen, optical means operatively associated with said auxiliary light source for directing at least a portion of the illumination from said auxiliary light source through said aperture onto the surface of the original to be reproduced to illuminate the original to be reproduced in relation to said aperture, and means for selectively energizing said auxiliary light source independent of the energization of said image reflecting light source to permit an operator to view an image to be produced and accurately position the original in registration with the aperture and said platen before making a reproduction of the original image.

Claim 6

In a reproducing apparatus in which an original to be reproduced is placed on a transparent platen overlying a projection aperture and illuminated with an image reflecting light source to project the information pattern through an optical system onto the surface of a photosensitive material, apparatus for aiding an operator in accurately positioning the original image to be reproduced in registration with the aperture and transparent platen comprising, an auxiliary light source supported within said reproducing apparatus in substantially non-interfering relationship with the image projecting optical system of said reproducing apparatus for illuminating at least a portion of the original to be reproduced during placement of the original onto said transparent platen, optical means operatively associated with said auxiliary light source for directing at least a portion of the illumination from said auxiliary light source through said aperture onto the surface of the original to be reproduced to illuminate the original to be reproduced in relation to said aperture, and means for selectively energizing said auxiliary light source independent of the energization of said image reflecting light source to permit an operator to view an image to be produced and accurately position the original in registration with the aperture and said platen before making a reproduction of the original image.
