Title:
磁気イメージセンサー
Document Type and Number:
Japanese Patent JP6564528
Kind Code:
B2
Abstract:
A magnetic image sensor is provided. The magnetic image sensor includes: a magnetic resistance (1), arranged along a scanning direction and configured to detect a changed magnetic signal in a range to be detected; a configuration resistance (2), connected with the magnetic resistance (1), wherein a resistance value of the configuration resistance (2) is adjustable; and a driving circuit (3), connected with the magnetic resistance (1) and configured to perform output control on the changed magnetic signal detected by the magnetic resistance (1) The problem of relatively stronger noise signal caused by a magnetic resistance deviation of a magnetic image sensor is solved.
