PROBLEM TO BE SOLVED: To provide a deflective scanner with which the transfer of vibrational noise of a laminated core generated when an electric current flows in a winding wire of an armature is suppressed and silence is realized. SOLUTION: The deflective scanner is provided with a rotatable rotor, having a laminated core pair in which an armature coil is wound around a laminated stator core and furnished with a power supply pin furnished for exciting the armature winding wire on a mounting substrate of which the bearing housing is positioned and supported and permanent magnets for driving facing to the laminated core pair in radial direction around the bearing housing, and which rotatable rotor serves as a rotating polygon mirror for deflecting a laser beam. The laminated core pair is characterized by that the laminated core pair is fixed only with the power supply pin on the mounting substrate. COPYRIGHT: (C)2005,JPO&NCIPI |
