PROBLEM TO BE SOLVED: To make detectable the magnetism of a magnetic medium without generating a magnetic material noise even when a pressing member is rotated. SOLUTION: This magnetic sensor device is provided with a magnetic sensor 1 for detecting the magnetism of a conveyed magnetic medium K by sensor elements 10a, 10b, and rotatable pressing rollers 7a, 7b for pressing the magnetic medium K to the sensor elements 10a, 10b of the magnetic sensor 1. The central parts of the pressing rollers 7a, 7b are displaced by a predetermined distance in the medium conveying direction from a line extended from the sensor elements 10a, 10b orthogonally to the medium conveying direction. |
