SCANNING UNIT AND IMAGE DISPLAY DEVICE

摘要

A scanning unit is provided with a reflecting section for reflecting laser beams, and an enclosure section whose hollow inside is filled with a movable substance. The scanning unit is characterized in that the movable substance moves corresponding to the angular velocity of the scanning unit, and the status of reflecting the laser beams at the reflecting section can be changed. In one example, the movable substance moves corresponding to the angular velocity of the scanning unit and covers at least a part of the reflecting section. In another example, the movable substance moves corresponding to the angular velocity of the scanning unit and deforms the reflecting section.
