    摘要： An exposure unit (10) includes first and second exposure heads (1A, 1B). The first exposure head (1A) includes: first light emitting devices (15A) each emitting a first light beam (L15A); a first optical system (11A) performing imaging of each of the first light beams (L15A); a first coupler (18A); and a first base member (12A). The first coupler (18A) is provided at a first position (P1), in the first base member (12A), based on a position at which the imaging performed by the first optical system (11A) is performed. The second exposure head (1B) includes: second light emitting devices (15B) each emitting a second light beam (L15B); a second optical system (11B) performing imaging of each of the second light beams (L15B); a second coupler (18B); and a second base member (12B). The second coupler (18B) is provided at a second position (P2), in the second base member (12B), based on a position at which the imaging performed by the second optical system (11B) is performed and is fit into the first coupler (18A).

    摘要： A line head includes a substrate, light emitting elements disposed on the substrate, drive circuits that drive the light emitting elements, and wirings that electrically connect the drive circuits and the light emitting elements. The light emitting elements form n (n≥2) light emitting element rows. The drive circuits are electrically connected with the wirings to light emitting elements belonging to a number of light emitting element rows equal to or smaller than n-1.

    摘要： An imaging system. An array of light sources and an array of lenses corresponding to the light sources and having optical axes substantially parallel to one another are provided. The lenses produce collimated output beams. An afocal optical relay having an optical axis substantially parallel to the optical axes of the lenses is also included, the array of lenses being positioned relative to the afocal optical relay so as to form an optical system that produces an image of each collimated output beam on an image plane, each image having a prescribed depth of focus and spot size. The light sources preferably are lasers producing an array of respective laser beams having high intensity and a long waist. A system for writing information on a light-sensitive label includes the imaging system. Methods of imaging and of writing information on a light-sensitive label are also provided.

    摘要： A line head (29), includes: an element substrate (293) that includes luminous element groups (295) as groups of a plurality of luminous elements (2951); and a lens array (299) that includes lenses which have an optical property of inverting or non-unity-magnification, focus light from the luminous element groups to form spot groups on an image plane, and are provided corresponding to the respective luminous element groups, wherein the plurality of luminous elements (2951) are two-dimensionally arranged in point symmetry in each luminous element group (295), a plurality of spots (SP) are formed as the spot group (SPG) when the respective luminous elements of the luminous element group emit light, and an inter-point distance between an intersection of a line extending from a symmetry center (SC) of the luminous element group in an optical axis (OA) direction of the lens with the image plane and a center of gravity position of the spot group is shorter than a specified distance.
