    摘要： An image projection apparatus includes: an image forming unit that forms an image using light from a light source; a projecting optical unit that forms a projected image of the image formed by the image forming unit; and an outer housing that houses the image forming unit and the projecting optical unit. The image forming unit and the projecting optical unit are provided in an order from a setting surface of the outer housing. A width of the outer housing in a direction perpendicular to a projection surface is larger at a position where the projecting optical unit is provided than at a position where the image forming unit is provided.

    摘要： An endless belt assembly includes one or more rollers, an endless belt, and a belt tracking mechanism. The one or more rollers are disposed parallel to each other, each being rotatable around a rotational axis thereof. The endless belt is looped for rotation around the rollers. The belt tracking mechanism is disposed on at least one side of the endless belt assembly to prevent lateral displacement of the endless belt during rotation. The belt tracking mechanism includes an annular recess, an annular flange, and a circumferential rib. The annular recess is perimetrically formed on a longitudinal end face of the roller. The annular flange is disposed in the annular recess to rotate freely with respect to the roller. The circumferential rib extends along a side edge of an interior circumferential surface of the endless belt to contact the annular flange upon lateral movement of the belt.
