PROBLEM TO BE SOLVED: To obtain a desired scan trajectory by enabling uniform vibration of an optical fiber.SOLUTION: An optical fiber scanner 1 includes: an optical fiber 6 guiding light a plurality of vibration generating units 10 arranged on an outer peripheral surface of the optical fiber 6 at positions having prescribed intervals to the base end side from an ejection end 6b of the optical fiber 6 at equal intervals in a circumferential direction, and vibrating the ejection end 6b of the optical fiber 6 in a plurality of directions and a vibration damping member 8 arranged on any position between the end part of the base end side of at least the vibration generating part 10 and the ejection end 6b of the optical fiber 6. The vibration damping member 8 has a same rotary body shape around the axis line of the optical fiber 6.COPYRIGHT: (C)2014,JPO&INPIT【課題】光ファイバの均一な振動を可能にして、所望の走査軌跡を得る。【解決手段】光を導光する光ファイバ6と、該光ファイバ6の射出端6bから基端側に所定の間隔をあけた位置の光ファイバ6の外周面に周方向に等間隔をあけて複数配置され、光ファイバ6の射出端6bを複数方向に振動させる振動発生部10と、少なくとも振動発生部10の基端側の端部と光ファイバ6の射出端6bとの間のいずれかの位置に配置された振動減衰部材8とを備え、該振動減衰部材8は、光ファイバ6の軸線回りに同一の回転体形状を有している光ファイバスキャナ1を提供する。【選択図】図1
