Document Type and Number:
Japanese Patent JP6992508
Kind Code:
B2
Abstract:
To provide an image display device enabling reciprocation uninfluenced by gravity even in the case where an image display element is reciprocated within a plane including a gravity direction.SOLUTION: An image display device includes: an image display element movably supported within a plane including a gravity direction; a first actuator for reciprocating the image display element; a second actuator for applying constant force against gravity to the image display element during the reciprocation of the image display element; and a driving force generation unit for controlling driving of the first actuator and the second actuator.SELECTED DRAWING: Figure 10
