DIFFERENTIAL TRANSFORMER TYPE MAGNETIC SENSOR

摘要

PURPOSE: The application of a differential transformer type magnetic sensor is provided to apply a highly precise differential transformer type magnetic sensor while forming a flat coil arranged on a substrate with a driving coil and a differential coil. CONSTITUTION: An image forming device(1) including a magnetic sensor comprises a device main body(100) in which a document transferring part(300) is mounted on a document reading part(200). The document transferring part functions as the document reading part and an automatic document transferring device. The document transferring part can consecutively transfer documents on a document loading part(301) to the document reading part. The document reading part comprises a document stand formed with transparent members, a CCD(Charge Coupled Device) sensor, a document reading slit. The CCD sensor outputs a read document into image data.
