The banknote drive mechanism may be arranged to transport a banknote from an input aperture to a stacking device. The banknote drive mechanism may delimit a first banknote pathway proximal to an input aperture, and a second banknote pathway proximal to the stacking device. A pivotable security gate arrangement may be included that is resiliently biased to project into the second banknote pathway. ## Claims ### Claim 1 A banknote validator comprising: a housing; a validation sensor means; and a banknote drive mechanism; wherein the banknote drive mechanism is arranged to transport a banknote from an input aperture to a stacking means, said banknote drive mechanism delimiting a first banknote pathway proximal to the input aperture, and a second banknote pathway proximal to the stacking means; characterised by a pivotable security gate arrangement that is resiliently biased to project into the second banknote pathway. ### Claim 2 (depends on 1) A banknote validator as claimed in claim 1, wherein the pivotable security gate arrangement comprises a plurality of security gate tines. ### Claim 3 (depends on 2) A banknote validator as claimed in claim 2, wherein the plurality of security gate tines is distributed laterally across the second banknote pathway. ### Claim 4 (depends on 3) A banknote validator as claimed in claim 3, wherein a security niche is disposed underneath the plurality of security gate tines in the second banknote pathway. ### Claim 5 (depends on 1) A banknote validator as claimed in claim 1, wherein an optical sensor is disposed in the second banknote pathway at a position in the second banknote pathway distal from the pivotable security gate arrangement. ### Claim 6 (depends on 5) A banknote validator as claimed in claim 5, wherein a cashbox ingress aperture is positioned between the pivotable security gate arrangement and the optical sensor. ### Claim 7 (depends on 1) A banknote validator as claimed in claim 1, wherein the validation sensor means includes an image capture window positioned adjacent to the first banknote pathway, wherein the image capture window is transparent to both visible light and infrared radiation, and wherein the image capture window is configured to emit visible fluorescent light when irradiated by ultraviolet light. ### Claim 8 (depends on 7) A banknote validator as claimed in claim 7, wherein the image capture window is constructed from a transparent polypropylene material that incorporates a visible fluorescence substance. ### Claim 9 (depends on 5) A banknote validator as claimed in claim 5, wherein the optical sensor is formed by an arcuate transparent light conduit disposed adjacent to an end of the cashbox ingress aperture that is downstream in the second banknote pathway. ### Claim 10 (depends on 6) A banknote validator as claimed in claim 6, wherein the pivotable security gate arrangement is disposed proximal to an end of the cashbox ingress aperture that is upstream in the second banknote pathway. ### Claim 11 (depends on 5) A banknote validator as claimed in claim 5, wherein a received banknote travelling along the second banknote pathway travels from an upstream position defined by the location of the pivotable security gate arrangement to a downstream position defined by the location of the optical light sensor. ### Claim 12 (depends on 11) A banknote validator as claimed in claim 11, wherein a received banknote, on reaching the downstream position defined by the location of the optical sensor, is reversed so that a trailing edge of said received banknote is positioned in the security niche to prevent removal of said received banknote from the banknote validator. ### Claim 13 (depends on 4) A banknote validator as claimed in claim 4, wherein the stacking means is configured to urge a received banknote from being positioned in the security niche into a secure cashbox.
