Definitions

  • An apparatus for processing dry silver recording material includes a heated first curved platen over which a [52] U.S. Cl. 354/297, 219/216 Continuous belt is driven to heat the be before engag [51] llrt- Cl.
  • the present invention overcomes the above disadvantages by providing an apparatus having therein a continuous belt which is driven over a first curved heated platen before engaging the recording material and carrying it over a second curved platen which is heated by a plurality of heaters.
  • the heaters are operated independent of each other to maintain uniform development platen temperature. Belt tension and the curved platens keep the processing material therebetween.
  • a platen situated close to an input opening in the device is heated to a high temperature so that the recording material being carried by the continuous belt, the belt already at the high temperature, is brought to the required development temperature very fast.
  • a further heater, independently controlled and spaced from said heater to heat the platen also heats the platen, but mainly to the extent of maintaining the temperature required for development of the recording material. Therefore, both sides of the recording material being processed are raised to the same temperature simultaneously.
  • Another object of the present invention is to provide a new and improved apparatus for processing recording material which is of simple design and minimum construction.
  • FIGURE is a sectional view of the apparatus embodying the present invention.
  • the drawing illustrates the invention and shows the apparatus 1 for processing of dry silver recording materials.
  • the apparatus is an image developer for thermally processed paper.
  • the dry silver recording material hereinafter referred to as paper 2
  • the dry silver recording material is transported along a selected path between an input opening 3 and an output opening.4.
  • Rollers 6 and 7 are the secondary and primary drive rollers respectively, while roller 8 is an adjustable idler.
  • a plurality of curved platens 9 and 10 are indirectly heated by a plurality of heaters ll, 12, and 13. These heaters are of the type commonly known as sheet heaters.
  • the heaters are intimitely bonded to .the curved platens by contact cement or high temperature adhesive using conventional techniques.
  • Appropriately placed theromocouples (not shown) sense the actual temperature of the platens in the area of the individual heaters, which are made from a material having high thermal conduction characteristics such as aluminium.
  • Conventional electronic control maintains the platens at the desired temperature.
  • the assembly may be of any desired or suitable width and enclosed in an insulating housing 14.
  • all supports and drive connections are made of material having a low thermal conductivity.
  • openings 3 and 4 are kept narrow. Thus, the entire system is conservative of space and construction is kept simple.
  • drive rollers 6 and 7 are synchronized to each other and driven by conventional means (not shown) such as a belt driven by a motor to move continuous belt 5 such that the exposed paper 2 introduced between platen 9 and belt 5 with the emulsion side against the belt in the direction indicated by arrow A from opening 3 will be transported through the apparatus and exit at opening 4.
  • conventional means such as a belt driven by a motor to move continuous belt 5 such that the exposed paper 2 introduced between platen 9 and belt 5 with the emulsion side against the belt in the direction indicated by arrow A from opening 3 will be transported through the apparatus and exit at opening 4.
  • the curvature of the platen 9 and the elasticity of the belt 5 combine to maintain intimate contact between the paper and heated belt and between the paper and heated platen, which causes the latent image to be developed.
  • the coefficient of friction between the belt and the emulsion side of the paper is greater than it is between the back of the paper and the platen. This effects transport; thus, the platens are polished which minimizes friction. Reducing friction, in turn, reduces power requirements of the platen heaters. Paper entering at opening 3 must be rapidly heated which requires the area around opening 3 to receive more thermal energy, say, than the area around opening 4. Thus, heater [2 has only to maintain the desired development temperature. Heater l3 and platen l maintain belt temperature slightly above the temperature of platen 9. This technique raises the temperature of the emulsion side of the paper to developmenttemperature at a fast rate, and minimizes the need to maintain belt temperature by thermal conduction through the material being processed. Thus, paper warm-up time is minimized allowing higher speeds for a given length of platen 9.
  • An apparatus for processing dry silver recording material comprising:
  • insulated housing means having an input opening through which the recording material is introduced into said insulated housing means and an output opening out of which the recording material is ex tracted from said insulated housing means;
  • first platen means disposed in said insulated housing means extending from said input opening to said output opening along which the'recording material moves;
  • roller means disposed in said housing means including input roller means adjacent said input opening, output roller means adjacent said output opening, and intermediate roller means between said input roller means and said output roller means, said continuous belt means movably mounted onto said input roller means, output roller means, and said intermediate roller means, said continuous belt means adapted to be moved via said roller means so that said continuous belt means engages said first platen means thereby frictionally moving the recording material along said first platen means;
  • heater means provided on said second platen means for heating said .second platen means which heats said continuous belt means above the temperature of said first platen means whereby said continuous belt means raises the temperature of the emulsion side of the recording material to development tem perature at a fast rate.
