A movement area of a stage includes first-fifth areas. In the first area, three of four heads except for a first head respectively face three of four sections of a scale member except for a first section. In the second area, three of four heads except for a second head respectively face three of four sections except for a second section of the scale member. In the third area, three of four heads except for a third head respectively face three of four sections except for a third section of the scale member. In the fourth area, three of four heads except for a fourth head respectively face three of four sections of the scale member. In the fifth area, the four heads respectively face the four sections. During exposure, the stage is moved from one of the first-fourth areas to another of those areas via the fifth area.
