The exposure head includes at least one light source of a broad area type, an optical waveguide gradually broadening in a broad area direction of the light source toward a traveling direction of light emitted from the light source, a member collimating the light traveling in a perpendicular direction to the broad area direction, the light being emitted from the optical waveguide and a light modulating device including a plurality of modulation units arrayed in the broad area direction. The image recording apparatus includes the above exposure head an optical system for focusing on a predetermined position the light emitted from the exposure head and a scanner for allowing the exposure head and a photosensitive material to move relatively, while regulating the photosensitive material at the predetermined position.

Exposure head and image recording apparatus

A light beam scanning device for scanning an object to read image information therefrom or record image information thereon includes a reflecting-mirror light deflector for reflecting and deflecting a light beam in a plane, and a scanning lens for passing the light beam deflected by the light deflector toward the object. An optical element such as a glass plate has an entrance surface for allowing the light beam to pass therethrough to the light deflector, and directs the light beam from the light deflector therethrough to the scanning lens. The entrance surface is inclined at a predetermined angle to a direction normal to an optical axis of the scanning lens.
