Combined magnetic shield member and pressure pad for a magnetic reader
View Patent ↗A magnetic shield member for a device with a magnetic reader, the magnetic shield member includes a biasing member including a first end, a second end opposite to the first end and an intermediate portion disposed between the first and second ends, the first end configured to be attached within the device with a magnetic reader, the second end configured to face the magnetic reader and a shielding member including a first end, a second end opposite to the first end and an arched portion disposed between the first end and the second end, wherein the first end of the shielding member extends integrally from the second end of the biasing member, the arched portion includes a concave portion which faces the magnetic reader, wherein the shielding member applies a force to conform a document against the magnetic reader and shields the magnetic reader from magnetic interference.
1. A magnetic shield member for a device with a magnetic reader, the magnetic shield member comprising:
a biasing member including a first end, a second end opposite to the first end and an intermediate portion disposed between the first and second ends, the first end configured to be attached within the device with a magnetic reader, the second end configured to face the magnetic reader, wherein the biasing member further includes a first obtuse angle between the intermediate portion and the first end and a second obtuse angle between the intermediate portion and the second end; and
a shielding member including a first end, a second end opposite to the first end and an arched portion disposed between the first end and the second end, the arched portion integrally connecting the first end of the shielding member with the second end of the shielding member, wherein the first end of the shielding member extends integrally from the second end of the biasing member, the arched portion includes a concave portion which faces the magnetic reader,
wherein the shielding member applies a force on the magnetic reader and shields the magnetic reader from magnetic interference.
2. The magnetic shield member of claim 1 , wherein the shielding member has at least one pressure pad having a rounded portion.
3. The magnetic shield member of claim 1 , wherein the second end of the shielding member extends in an arc shape to connect with the biasing member.
4. The magnetic shield member of claim 3 , wherein the magnetic shielding member further comprises a shielding sidewall which encloses at least one side of the shielding member.
5. The magnetic shield member of claim 1 , wherein the shielding member is formed of a magnetic permeability material including a nickel-alloy.
