Title:
振動走査ミラーアセンブリ
Document Type and Number:
Japanese Patent JP4669549
Kind Code:
B2
Abstract:
An improved oscillation scan mirror assembly comprises a shaft, a holder having a bearing with a bearing surface supporting the holder on the shaft, a scan mirror secured to the holder. The holder and therefore the mirror are oscillatable around the shaft under an oscillating driving force, and bearing and the shaft is prevented from being tilt from each other. Preferably, a lateral retaining force is provided to constantly keep the bearing and the shaft in an aligned contact with each other. Since the relative tilting between bearing and the shaft is prevented, the vertical wobble or vibration of bearing, and therefore of the holder and the mirror, relative to the shaft is therefore suppressed.
