Abstract:
An image projection apparatus includes an image generator configured to use light emitted from a light source to generate an image; a movable member in which the image generator is disposed, the movable member being movably supported; a fixed member being fixed and configured to movably support the movable member; and a mover configured to move the movable member. The mover includes a first pair of actuators facing each other in a first direction across the image generator, and a second pair of actuators facing each other in the second direction across the image generator. The first pair of actuators causes a driving force to operate on the movable member in a direction parallel to a second direction orthogonal to the first direction. The second pair of actuators causes a driving force to operate on the movable member in a direction parallel to the first direction.
