ABSTRACT:
In a rotating mirror scanner, a polygonal mirror is fixed between a pair of journals of a spindle. A rotor is fixed on the spindle, and a rotor magnet constituting a magnetic thrust bearing is fixed to one end of the spindle. One bearing of a dynamic pressure type and a ring-shaped stator magnet which constitutes the magnetic thrust bearing are both fixed in a hollow housing having an opening. The spindle is inserted into the housing through the opening thereof so that the outer peripheral surface of the rotor magnet faces the inner peripheral surface of the stator magnet, and that one journal is fitted in the one bearing. Thus, the spindle is set in the housing. A cover having the other bearing is fitted in the opening of the housing so that the other journal is supported by the other bearing.
