Apparatus for producing microform records includes an image-reducing projection system positioned above a hard copy and transparency-receiving imaging station defining a horizontal document plane. An opaque platform is located at the document plane for supporting hard copy and a transparent plate is located at or near the document plane for supporting a transparency. Overhead lamps are provided to direct light downwardly upon the hard copy, and a light source, preferably a cathode ray tube, is provided below this document plane to project light upwardly through the document plane. The cathode ray tube or other light source produces a uniform light field or image-containing light field, the former when a transparency is placed at said document plane, the latter either when a transparency is or is not located at or near said document plane. When an image-containing light field is directed through a transparency at the document station, the microform record produced includes both the image in the image-containing light field and the object of the transparency as an overlay of the same.
In an apparatus for producing microform records from light reflecting hard copy wherein a light image reflected from the hard copy is reduced to micro-image size and applied at a film imaging station to film means which is photosensitive to an image by the light reflecting hard copy, said apparatus including a hard copy-supporting station including a generally horizontal, opaque, hard copy-supporting platform, lighting means mounted above said platform which lighting means is to be energized when a record of a piece of hard copy placed on said platform is to be made, an image-receiving and projecting means for receiving hard copy reflected light from a piece of hard copy placed on said platform and for providing a micro-image thereof directed upon said film means, the improvement wherein said platform is mounted for movement between an operative horizontal position at said supporting station and a position removed therefrom, a transparent plate provided at said supporting station exposed when said platform is removed therefrom for placement of a transparency thereon, and light field producing means for projecting upwardly through said transparent plate and into said image-receiving means selectively a uniform light field where the image on the transparency is to be the only image to be recorded on said film means or an image-containing light field where the image on said transparency is to be superimposed upon the image of said image-containing light field.
In an apparatus for producing microform records from light reflecting hard copy wherein a light image reflected from the hard copy is reduced to micro-image size and applied at a film imaging station to film means which is photosensitive to an image by the light reflecting hard copy, said apparatus including a hard copy-supporting station including an opaque hard copy-supporting platform and image-reducing projection means for directing upon said film means a micro-image of the light reflected image from hard copy placed on said platform, the improvement wherein there is provided a transparency supporting station including transparency-supporting means and means for directing through a transparency on said supporting means and into said projection means a light field which projects the image on said transparency upon said film means, said light field directing means being a cathode ray tube, and means for energizing said cathode ray tube to provide a light field on the screen thereof which is projected through said transparency-supporting means into said projection system.
In an apparatus for producing microform records including an image-receiving and projection means for receiving light images and for providing a micro-image thereof directed upon said film means, the improvement comprising a transparency-supporting station including transparency-supporting means and means for directing through a transparency on said supporting means and into said projection means a light field which projects the image on said transparency upon said film means, said light field directing means being a cathode ray tube, and means for energizing said cathode ray tube to provide a light field on the screen thereof which is projected through said transparency-supporting means into said image-receiving and projection means.
In an apparatus for producing microform records said apparatus including an image-receiving and projecting means for receiving light-defined images and for providing a micro-image thereof directed upon film means, the improvement comprising a transparent transparency support means facing said image-receiving means and provided for placement of a transparency thereon, an image-containing transparency on said support means, and light field producing means on the opposite side of said support means facing said image-receiving means for selectively projecting through said transparency support means and the transparency thereon and into said image-receiving means a uniform light field where the image on the transparency is to be the only image to be recorded on said film means or an image-containing light field where the image of said image-containing light field is to be superimposed upon the image of said transparency.
