Abstract
An image projector includes a first deflector configured to deflect a first optical path and to form a second optical path, a second deflector configured to deflect the second optical path and to form a third optical path, a shifter configured to shift a projection lens in a vertical direction which corresponds to a longitudinal direction of the projected surface among directions orthogonal to an optical axis of the projection lens, a housing configured to house the first deflector and the second deflector, and a fixed plate fixed onto the housing at an end on an installing surface side of the housing, the projection lens and the shifter being fixed onto the fixed plate, wherein the third optical path is closer to an installing surface of the housing than the first optical path.
