Combined magnetic shield member and pressure pad for a magnetic reader

Abstract

A point of sale (POS) device is provided and includes a magnetic ink character reader (MICR), and a magnetic shield member. The magnetic shield member includes a biasing member, a first shielding member and a second shielding member. The first shielding member applies a force on the MICR and the first and the second shielding members shield the MICR from magnetic interference.

1 . A point of sale (POS) device, comprising:
 a magnetic ink character reader (MICR), which is configured to read magnetically recorded data from a document inserted in the POS device; and   a magnetic shield member including:
 a biasing member including a first end configured to be attached to the MICR within the POS device, a second end opposite to the first end and being configured to face the MICR, and an intermediate portion disposed between the first and second ends to form 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, 
 a first shielding member including a first end, which extends integrally from the second end of the biasing member, a second end opposite to the first end and a first arched portion disposed between the first end and the second end, which integrally connects the first end thereof with the second end thereof, and which includes a concave portion configured to face the MICR with the document disposed therebetween, and 
 a second shielding member, which extends integrally from the second end of the first shielding member and which includes a second arched portion including a concave portion configured to face the first arched portion, wherein 
   the first shielding member applies a force on the MICR and the first and the second shielding members shield the MICR from magnetic interference.
