Abstract

Abstract A banknote examining device comprises a slot (2) formed in a tabletop (1) beneath which there is mounted a UV-lamp displaced in relation to the slot (2). Part of a banknote (11) inserted into the slot will be irradiated with UV-radiation and a teller is able to ascertain the genuineness of a banknote by checking fluorescent security print thereon.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 81 words
A banknote examining device for checking UV-fluor­escing security print and the like with the aid of a UV-lamp intended for illuminating a banknote and screened against direct radiation, charac­terized by a slot (2) formed in a table, through its tabletop (1), wherein the UV-lamp (4) is mounted beneath and to one side of the slot (2) formed in said tabletop, such that an externally visible part of a banknote (11) inserted into the slot is irradiated with UV-radiation from the UV-lamp.
Claim 2
Dependent Claim 81 words
A banknote examining device for checking UV-fluor­escing security print and the like with the aid of a UV-lamp intended for illuminating a banknote and screened against direct radiation, charac­terized by a slot (2) formed in a table, through its tabletop (1), wherein the UV-lamp (4) is mounted beneath and to one side of the slot (2) formed in said tabletop, such that an externally visible part of a banknote (11) inserted into the slot is irradiated with UV-radiation from the UV-lamp.
Claim 3
Dependent Claim 35 words
A device according to Claim 1, charac­terized in that the slot is configured in a fit­ting (3) which is mounted so that its upper surface lies substantially flush with the upper surface of the tabletop.
Claim 4
Dependent Claim 28 words
A device according to Claim 1 or 2, charac­terized in that a black covering (9) is located adjacent the slot (3) on the upper surface of the tabletop.
Claim 5
Independent Claim 40 words
A device according to any one of the preceding Claims, characterized in that the UV-lamp can be raised to a position above the tabletop and is provided with a screen (5) which, in said raised posi­tion, shields against direct viewing.
Claim 6
Independent Claim 68 words
A device according to any one of the preceding Claims, characterized in that there is arranged on the opposite side of the slot (2) with respect to the position of the UV-lamp (4) a fluorescence plate which is intended to be shadowed by an inserted banknote but, when illuminated by the UV-­lamp, to generate visible light through the slot (2) so that the banknote can be seen through.
Claim 7
Independent Claim 106 words
A device for checking UV-fluorescent security print and the like with the aid of a UV-lamp intended for illuminating a banknote and screened against direct radiation, and including illuminating means for visible light, therewith to enable a banknote to be seen through for the purpose of checking watermarks and the like, characterized in that the illumina­ting means for visible light comprise a surface which fluoresces in visible light and which is irradiated by the UV-lamp and which is shadowed by means of a bank­note inserted between the UV-lamp and said means, thereby enabling one and the same light source to be used for both checking purposes.
Claim 8
Independent Claim 106 words
A device for checking UV-fluorescent security print and the like with the aid of a UV-lamp intended for illuminating a banknote and screened against direct radiation, and including illuminating means for visible light, therewith to enable a banknote to be seen through for the purpose of checking watermarks and the like, characterized in that the illumina­ting means for visible light comprise a surface which fluoresces in visible light and which is irradiated by the UV-lamp and which is shadowed by means of a bank­note inserted between the UV-lamp and said means, thereby enabling one and the same light source to be used for both checking purposes.
