Abstract

Abstract A device for deactivating price tags of the kind provided with a magnetic strip intended to form part of an anti-theft store security system, said device being intended for use together with a so-called scanner used to optically read a bar code on an item of goods. The invention is characterized in that the deactivator (2) includes two or more mutually adjacent and mutually parallel rows (4, 5) of permanent magnets (6, 7), where the magnets (6) in one row (4) form pairs of permanent magnets, partly with surrounding magnets in said row and partly with adjacent magnets (7) in an adjacent row (5), said paris (6, 7) being disposed in a plane which is completely or substantially parallel with the plane in which the bar code on a goods item is located when reading said code; in that the south pole of a first magnet (6) in said magnet pair is located on a magnet surface facing away from the deactivator (2) and the north pole of said first magnet is located on a magnet surface which faces towards the deactivator (2); and in that the respective south and north poles of a second magnet (7) of said magnet pair face in opposite directions.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 179 words
A device for deactivating price tags of the kind provided with a magnetic strip intended to form part of an anti-theft store security system, said device being intended for use together with a scanner used to optically read a bar code on an item of goods, characterized in that the deactivator (2) includes at least two mutually adjacent and mutually parallel rows (4, 5) of permanent magnets (6, 7), where the magnets (6) in one row (4) form pairs of permanent magnets, partly with surrounding magnets in said row and partly with adjacent magnets (7) in an adjacent row (5), said pairs (6, 7) being disposed in a plane which is completely or substantially parallel with the plane in which the bar code on a goods item is located when reading said code; in that said south pole of a first magnet (6) in said magnet pair is located on a magnet surface facing away from the deactivator (2) and in that the respective south pole of a second magnet of said magnet pair faces in an opposite direction.
Claim 2
Independent Claim 179 words
A device for deactivating price tags of the kind provided with a magnetic strip intended to form part of an anti-theft store security system, said device being intended for use together with a scanner used to optically read a bar code on an item of goods, characterized in that the deactivator (2) includes at least two mutually adjacent and mutually parallel rows (4, 5) of permanent magnets (6, 7), where the magnets (6) in one row (4) form pairs of permanent magnets, partly with surrounding magnets in said row and partly with adjacent magnets (7) in an adjacent row (5), said pairs (6, 7) being disposed in a plane which is completely or substantially parallel with the plane in which the bar code on a goods item is located when reading said code; in that said south pole of a first magnet (6) in said magnet pair is located on a magnet surface facing away from the deactivator (2) and in that the respective south pole of a second magnet of said magnet pair faces in an opposite direction.
Claim 3
Dependent Claim 21 words
A device according to claim 1, characterized in that the deactivator (2) includes more than two parallel rows of permanent magnets.
Claim 4
Independent Claim 54 words
A device according to claims 1 or 2, characterized in that said deactivator (2) is fixedly mounted relative to the scanner (1) in a position relative to said scanner such that the price tag on a goods item will pass against or close to the deactivator when reading the bar code on said item.
Claim 5
Dependent Claim 15 words
A device according to claim 3, characterized in that the deactivator (2) is resiliently mounted.
