摘要： An exposure head includes a substrate through which light from light-emitting elements provided on a first surface of the substrate penetrates from the first surface to a second surface. A rod lens array is provided on the second surface of the substrate to image the light from the second surface. A light transparent member is provided between the substrate and the rod lens array and fixed to the second surface of the substrate and the rod lens array. A support member supports the first surface of the substrate.

摘要： In a line head, a plurality of light emitters are arrayed on a substrate in a first direction. Each of the light emitters is operable to emit a light beam. In a rod lens array, a plurality of rod lenses are arrayed in the first direction, and each of the rod lenses is adapted to focus the light beam emitted from an associated one of the light emitters onto a target surface. The substrate and the rod lens array are attached to a holder elongated in the first direction. Positioning members are provided at both end portions of the holder in the first direction. A relative position between the substrate and at least one of the positioning members is variable in a second direction perpendicular to the first direction.

摘要： An exposure head includes: a first light emitting device group including light emitting devices disposed at different positions in a direction perpendicular or approximately perpendicular to a moving direction of an exposed side; a second light emitting device group disposed in the moving direction of the exposed side with respect to the first light emitting device group; an imaging optical system imaging light from the light emitting devices to expose the exposed side; and a control unit allowing one light emitting device group out of either the first light emitting device group or the second light emitting device group to emit light on the basis of a driving signal.

摘要： A line head includes light-emitting element lines formed by arranging a plurality of light sources in a line shape in a main scanning direction. Each of the light sources is turned on/off corresponding to image data. Light beams emitted from the light sources pass through a lens array to form imaged spots on an exposed surface. The imaged spots generated by making the light beams emitted from the plurality of light sources imaged on the exposed surface are shifted by inches in the main scanning direction or a sub-scanning direction so as to overlap each other, thereby forming images. A gray-scale image of the images has a screen structure displayed on the basis of an area of dots or lines having a predetermined pitch. A diameter of each of the imaged spots formed on the exposed surface is set to be larger than a pitch between pixels and smaller than a pitch between lines or dots forming the screen. Gradation of an image is displayed by a combination of binary states of ON/OFF of each of the light sources.
