Paper sheet magnetic detection apparatus

摘要

The object is to avoid degradation of magnetic detection precision arising due to magnetization of transport rollers used for transporting a paper sheet. A paper sheet magnetic detection apparatus that detects a magnetic material in the paper sheet by using a magnetic sensor includes a transport path that transports paper sheets one by one; at least one magnet that is used in the detection of the magnetic material by the magnetic sensor; and a plurality of transport rollers that are arranged near the magnetic sensor and that transport the paper sheet in the transport path. Outer peripheral surfaces of the plurality of transport rollers that face the transport path are made of a nonmagnetic material.
