Abstract: A magnetism detection device capable of improving the ability to detect magnetic features of coins and reducing a change in outputs due to a change in transport positions of coins, a coin recognition device, and a method for detecting magnetism using the magnetism detection device. The magnetism detection device includes a transport path on which a coin is to be transported, detection coils arranged on at least one side of a transport surface of the transport path and along a direction crossing a transport direction of the coin, and a controller configured to detect a magnetic feature of the coin based on an output signal from at least one but not all of the detection coils.

Abstract: Provided is a magnetic detection device (100) having a simple configuration and being capable of stably detecting fine portions of a coin. The magnetic detection device (100) comprises an excitation coil (LX) that generates an alternating magnetic field in a transport path for transporting a coin in a first direction, and a plurality of detection coils (L1, L2) that are arranged at a predetermined pitch in a second direction and that output a detection signal based on an induction voltage caused by the alternating magnetic field. Each of the plurality of detection coils (L1, L2) outputs a detection signal on the basis of the induction voltage induced by the alternating magnetic field, which changes due to the coin being transported along the transportation path.

Abstract: 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 non-magnetic material.
