摘要： 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.

摘要： A lighting unit and an image projector that cool a drive source that drives a color wheel favorably and prevents dust from collecting on the color wheel are provided. The lighting unit includes a color wheel that divides light from a light source into colors different from each other time-divisionally, a drive source that drives the color wheel such as a color motor, and an optical device that illuminates light that passes through the color wheel on an image generating device such as a DMD that generates a projection image. The lighting unit includes a cooling device that draws heat from the drive source to cool the drive source.
