Definitions

  • the present invention in general, is directed to scanners. More particularly, the present invention is directed to an apparatus and method for scanning paper currency for the purpose of verifying the authenticity as well as determining the value thereof.
  • Conventional paper-currency scanning devices are, e.g., typically associated with vending machines that provide consumers with beverages and snacks as well as separate mechanisms located in, e.g., recreational areas having casino slot machines that accept paper currency and/or video arcades that provide coins in exchange for paper currency.
  • Such scanning devices typically employ a light source to illuminate the currency as well as a detector system that picks-up features or characteristics from the currency.
  • a number of conventional paper currency-scanning devices and systems further frequently incorporate at least one light source as well as an associated collimating lens for producing a beam of substantially parallel light rays that pass through and illuminate the paper currency from one side thereof.
  • an associated planar/convex lens for gathering scatter rays from the bill, and which thereafter provides the gathered scatter rays to an associated detector that is designed, in ideal situations, to be capable of verifying the authenticity as well as detecting the value of the scanned bills.
  • the convex lens is typically so spaced from a desired scanning plane (for the paper currency) such that the focal point of the lens ideally touches the scanning plane.
  • indicia and other characteristics incorporated into current paper currency for security reasons are capable of providing light passing through the scanned bill with information that is compared to certain stored information, for the purpose of verifying authenticity as well as value of the paper currency being scanned.
  • paper by its nature diffuses light.
  • diffused light passing through a bill located in the desired scarining plane, which is thereafter focused may fall short of the detector entirely, or the light rays passing through the convex lens may focus light from the scanned bill behind a desired detection zone, either of which is undesirable.
  • conventional currency-scanning devices may include, as the light sources thereof, certain light-emitting diode devices (or so- called "packages"), that are capable of providing light of multiple wavelengths.
  • LEDs state-of- the-art light-emitting diodes
  • a single currently commercially-available LED package capable of operating from blue to infrared, when incorporated into the above- described conventional currency-scanning device, is able to provide the scarining device with a source of light having the characteristic wavelengths of 470, 505, 620, 730, 840 and 940 nanometers.
  • the present invention is directed to a scanner apparatus that does not require a collimating lens. Instead, the scanner apparatus incorporates a waveguide. Moreover, the resulting design of the scanner apparatus of the invention has enabled reducing the number of light-emitting diode (LED) packages from twelve or more to four or less.
  • LED light-emitting diode
  • the scanner apparatus of the invention is preferably used to scan paper currency for the purpose of verifying the authenticity as well as determining the value thereof.
  • each such LED package is preferably so disposed and positioned, relative to the currency-scanning plane, as to scan a different quarter portion of the paper currency.
  • the scanner apparatus of the present invention comprises a scanning zone, at least one light-emitting diode, at least one light detector, and a waveguide.
  • the scanning zone of the scanner defines opposed sides and is dimensioned to enable a scannable article to be disposed between the opposed sides thereof.
  • the light-emitting diode device is disposed on one side of the scanning zone, and is capable of providing light of discreetly-different energy levels. Also, the light-emitting diode device is so disposed relative to the scanning zone as to enable light associated with such diode device to be able to scan at least a portion of the scannable article.
  • the light-detector device is spaced from the light-emitting diode, and is also so disposed relative to the scanning zone of the scanner, that light emanating from the light-emitting diode device and thereafter passing through the scanning zone, is able to provide information, enabling the light detector to characterize the article scanned in the zone.
  • the wave guide is disposed between the light-emitting diode device and scanning zone.
  • the wave guide defines at least one light-admitting aperture and at least one light-reflective surface, wherein the light-admitting aperture and the light- reflecting surface cooperate to direct light from the light-emitting diode device toward the scanning zone, and to focus such light centrally along a path traveled by such light toward the detector.

  • like reference numeral refer to like component parts.
  • Figure 1 depicts, as a schematic view, a conventional apparatus 100 for scanning paper currency.
  • the apparatus 100 includes an opening or aperture 102 typically taking the form of an elongated slot for inserting paper currency into the apparatus 100.
  • the currency-insertion aperture or opening 102 includes an upper boundary 104 and a lower boundary 106.
  • Currency (not shown) inserted through opening 102 into the apparatus 100 ideally is caused to travel along a path 110 (shown in dotted line) that may be thought of as a plane extending into the page of Figure 1 of this patent specification.
  • the currency-scanning apparatus 100 also includes a plurality of light- emitting diodes (LEDs) 114 that are spaced from the lower boundary 106 generally uniformly along the length thereof. As was noted above, twelve or more of the above-described LED packages 114 must necessarily be incorporated into the scanning apparatus 100, if the apparatus 100 is to verify currency authenticity and value, thereby to achieve its commercial purpose.
  • LEDs light- emitting diodes
  • each lens 116 is similarly spaced from the lower boundary 106 generally uniformly along the length thereof.
  • each such collimating lens 116 is associated with its corresponding LED package 114. Accordingly, as a result of the scanner arrangement shown, each such collimating lens 116 is located between the lower boundary 106 and its associated LED package 114.
  • the currency-scanning apparatus 100 of Figure 1 further includes a corresponding plurality of simple planar convex light-focusing lenses 122.
  • Each such simple planar convex light-focusing lens 122 is disposed between the upper boundary 104 and an associated currency authenticity/valuation detector 120. In ideal situations, each such simple planar convex light-focusing lens 122 is capable of focusing light passing through the paper currency onto a preselected portion (or point) of its associated detector 120.
  • the plural simple planar convex light-focusing lenses 122 focus light to enable the plural detectors 120 to detect certain light-energy levels, for the purpose of verifying the authenticity of the inserted currency as well as detecting the value thereof.
  • the currency-scanning apparatus 100 shown in Figure 1 accordingly necessarily further includes a corresponding plurality of detectors 120, each of which is capable of verifying the authenticity of currency and detecting the relative value thereof.
  • the plural detectors 120 are by current design spaced from the upper boundary 104 generally uniformly along the length thereof.
  • Each detector 120 is associated with a corresponding light-focusing lens 122 as well as with a corresponding LED package 114 and collimating lens 116, for reasons stated above.
  • Conventional scanners still have problems. As was mentioned above, movement of paper currency above or below its desired scanning plane may take the bill out of the focal point of light-focusing convex lens 122. Also, paper by its nature diffuses light.
  • the resultant diffused light that passes through a bill located in the scanning plane 110, which light is thereafter focused may fall short of one or more of the plural detectors 120 entirely, or the light rays passing through one or more of the plural convex lens 122 may focus light from the scanned bill behind a desired detection zone of an associated detector 120, either of which result is undesirable.
  • Aligning each LED package 114 with associated lenses 116 and 122 is a major obstacle faced by current scanner manufacturers and misalignment is common. Unnecessary complexity may result in excessive cost of the apparatus, and may affect reliable operation thereof. It is therefore desirable to reduce the complexity of a scanner apparatus by reducing the number of LED packages and associated components now required in state-of-the-art paper-currency scanners, thereby allowing for reduction of the above mentioned associated components, resulting in a less complex apparatus.
  • Multiplicity of component parts may undesirably impact on volume requirements and associated appearance considerations of conventional scanners. To minimize volume requirements, reduction of the number of components may therefore become desirable. It is further desirable that the resultant less-complex apparatus nevertheless be capable of verifying the authenticity of currency and determining its denomination or value with very high reliability and accuracy and statistically significant precision.
  • Figure 2 depicts, in schematic, one embodiment of the scanner apparatus 200 of the present invention.
  • Apparatus 200 is preferably used to scan paper currency to verify authenticity and determine the value thereof.
  • Currency-scanner apparatus 200 includes no more than four light-emitting diode packages 214, the location of which will be described below in connection with Figure 4.

Proceeding closer to central axis A-A minute grooves 236A are even more closely spaced ( Figure 5A) so as to cause a second portion of the six wavelengths of light from LED packages 214 to be concentrated centrally toward axis A-A. Additional minute grooves (not shown) are accordingly symmetrically formed in the grooved surface 236 relative to the central axis A-A until all six wavelengths of light from LED package 214 are centrally concentrated.
