Abstract

A magnetic sensor device includes magnetic detection elements arrayed along a line intersecting the relative movement direction of a medium, and a magnet applying a bias magnetic field to the magnetic detection elements with a line of magnetic force in the constant direction. The magnetic sensor device detects a magnetic field change when a medium with a magnetic pattern passes through the bias magnetic field as an electric signal through the magnetic detection elements and reads the magnetic pattern of the medium. A plurality of reading switches is connected to the respective magnetic detection elements and an output line common to the magnetic detection elements. The magnetic sensor device includes a shift register closing the reading switches sequentially one by one to transfer the outputs from the magnetic detection elements sequentially one by one to the output line.
