To reduce the noise generation by the high-speed rotation of laser printer and to miniaturize a product by using the scanning motor of a magnetic force bearing system.
The magnetic bearing device constituted to include a stationary shaft 14 which is the center of rotation of a rotary object, a housing 12 in which this stationary shaft is press fitted and fixed, a magnetic thrust stationary magnet 15 which is fixed to the inner peripheral surface of the stationary shaft, a magnetic radial stationary magnet 16 which is fixed atop this housing, a hub 17 to which the rotary object is fixed, a magnetic thrust rotary magnet 18 and magnetic radial rotary magnet 19 which are installed to this hub so as to respectively correspond to the magnetic thrust stationary magnet and the magnetic radial stationary magnet and maintain the specified spacing between the hub, the housing and the stationary shaft is provided.
