Definitions

  • the present invention relates to an apparatus for detecting counterfeit paper currency.
  • U. S. Patent No. 5,063,163 discloses a method of detecting counterfeit paper currency where a test solution having an initial color is applied to an area of a paper currency to be tested. After waiting for a predetermined time period, the color of the test area is compared with a predetermined standard to determine if a reaction has taken place. If the tested currency is a counterfeit paper currency, the test solution changes its color from the initial color to a black coloration. Even though the above solution is relatively simple, it is not always reliable.
  • Paper currency now includes a polymer thread, which is embedded vertically in the paper to the right of the portrait and indicates the currency's denomination. This thread glows orange when held under an ultraviolet light.
  • the '288 Patent discloses an apparatus incorporating an ultraviolet lamp for currency examination. Unfortunately, such conventional devices utilizing ultraviolet lamps are expensive to manufacture, and in most cases, are rather bulky and complex in design.
  • a counterfeit currency detector including a tubular body having a forward end and a rearward end, a contact assembly mounted at the forward end of the tubular body, and a counterfeit solution applicator mounted at the rearward end of the tubular body.
  • the contact assembly includes an ultraviolet light source.
  • FIG. 1 is a front view of the counterfeit detector pen showing a mounted ultraviolet light source and a counterfeit solution applicator.
  • FIG. 2 is a cross-sectional view of the forward end of the counterfeit detector pen.
  • FIG. 3 is a cross-sectional view of the contact assembly.
  • FIG. 4 is a cross-sectional view of the rearward end of the counterfeit detector pen.
  • a counterfeit detector pen 10 which generally includes a tubular body 12 having an ultraviolet light source 14, mounted in a contact assembly 16 at the forward end 18 of the tubular body 12, and a counterfeit solution applicator 20 mounted at the rearward end 22 of the tubular body 12.
  • a cap 46 may be secured over the rearward end 22 to protect the applicator 20.
  • the contact assembly 16 preferably includes a rotatable skirt 24 having a threaded end 26, the ultraviolet light source 14, a battery 28, both fixedly positioned within the rotatable skirt 24, and a biasing element 30 attached to the threaded end 26 of the rotatable skirt 24.
  • the forward end 18 of the tubular body 12 is a first hollow cylindrical tube 36 with an inner threading 32.
  • a protruding switch 34 is fixedly secured within the first hollow cylindrical tube 36.
  • the threaded end 26 of the rotatable skirt 24 is screwed into the inner threaded surface 32.
  • a user In use, to detect a counterfeit currency, a user will rotate the skirt 24 to turn the ultraviolet light source 14 ON and will flash the ultraviolet light onto the tested currency. If the tested currency is real the embedded vertical polymer thread will glow orange under the ultraviolet light.
  • the inventors herein have produced an embodiment (which they have reduced to practice), which utilizes at least one UV LED made by Nichia Corporation as part number NSPU510CS.
  • the particular UV LED has a peak wavelength at 375 nanometers with a range of 370 to 380 nm, with a spectrum half width of 15 nanometers.
  • the directivity, i.e., the radiation angle is in the range of 0-20 degrees, but can be up to 40 degrees.
  • the optical power output is typically in the range of 6800-9600 micro watts at a driving current of 15 milliamps but the invention contemplates that the optical power output can be in the range of 4800 to 13600 microwatts.
  • the invention concentrates the UV optical power output advantageously unto the currency being tested, where most needed.
  • the rearward portion of the counterfeit detector pen 10 includes a second hollow cylindrical tube 38 shown in more detail in FIG. 4 .
  • Diameter of the second cylindrical tube 38 is preferably smaller than the diameter of the first cylindrical tube 36.
  • the second cylindrical tube 38 preferably includes a tapered end 40 into which the counterfeit solution applicator 20 is inserted to be secured therein.
  • Applicator 20 is impregnated with a test solution, which can be applied to the currency to be tested using an applicator's tip 42.
  • the applicator 20 may include a reservoir filled with the test solution and connected to the applicator's tip 42.
  • Test solution preferably detects the content of starch in the currency paper. However, any other known test solution may be utilized.
  • a user will generally apply the test solution to the tested currency using the tip of the applicator 20.
  • the preferred solution which is light golden-brown in color, when applied to a counterfeit paper currency, forms a bluish-black complex with starch.
  • the color of the preferred test solution does not change in the case of a genuine paper currency.
  • the test solution is preferably a reagent solution described in U. S. Patent No. 5,063,163 .
  • the reagent solution preferably contains iodine and a suitable solvent, preferably selected from the group consisting of alcohol, carbon disulfide, chloroform, ether, carbon tetrachloride, glycerol, and an alkaline iodide solution.
  • the alkaline iodide may preferably be selected from the group consisting of sodium iodide and potassium iodide.
  • the light golden-brown test solution contains about 0. 5% to about 2.0% iodine, about 48.0% to about 49.5% water, and about 44% to about 50% alcohol by volume of the reagent solution.
  • the solution may also contain up to about 6% of a bleaching agent, such as hydrogen peroxide, by volume of the solution. It should be noted that various percentages of the noted ingredients may be altered in order to provide various test solutions of varying strengths.
  • the main component of the test solution is the iodine element. Other types of iodine solutions suitable for the described purpose may also be used with the described counterfeit detector pen.
  • the counterfeit detector pen 10 is approximately the same size as a pen, and may be easily carried in a purse or a pocket.
  • a clip 44 may be secured to the outer surface of the tubular body 12 to enable a user to carry the counterfeit detector pen in a pocket.
  • the invention improves and facilitates the detection of paper currency counterfeits, by providing dual mode of testing for counterfeiting.
  • the present invention provides a pen like device with two modes of testing, unlike the currency counterfeiting testing apparatus of the prior art.
