MAGNETIC RECORDING MEDIUM READER

摘要

A card reader (100) is provided with a magnetic field generating section (3) that generates an interfering magnetic field. The magnetic field generating section (3) is configured from an interfering magnetic field generator (31) and an interfering magnetic field generator (32), which are disposed to face each other. The interfering magnetic field generated from the interfering magnetic field generator (31) passes the interfering magnetic field generator (32), and the interfering magnetic field generated from the interfering magnetic field generator (32) passes the interfering magnetic field generator (31). In a region between the interfering magnetic field generator (31) and the interfering magnetic field generator (32), the directions of the interfering magnetic fields generated from respective interfering magnetic field generators are identical to each other.
