PROBLEM TO BE SOLVED: To obtain a compact and thin high-performance magnetic sensor device that can be manufactured inexpensively and can detect a plurality of signals. SOLUTION: A magnetic encoder device has a traveling disk 5 with a slit for detecting a position, a magnetic sensor 1 that is arranged via the traveling disk and an air gap, a bias magnet 2 that is provided on the rear surface of the magnetic sensor, and a signal-processing circuit 6 for processing a signal from the magnetic sensor. Also, the device has a slit track 31 for detecting a position with a slot for detecting a position, a slit track 33 for detecting the magnetic pole of a motor, and a slit track 32 for detecting a zero point with a slot for detecting the zero point position. At the same time, a magnetic sensor with a bias magnet is arranged at the position of the slit track. |
