    摘要： An optical write-in head for obtaining a clear image even in printing at a relatively high recording density without generating strip-like irregularities in most cases. The optical write-in head applies light carrying image information to a photosensitive substance. The optical write-in head includes an array light source having a plurality of dot light sources, each of which selectively emits the light corresponding to the image information, and a lens array facing the array light source. The lens array has a plurality of lens elements which corresponds to the plurality of dot light sources respectively. An angular aperture θ of each of the lens elements is set in a range of about 14° to 18°.

    摘要： An erecting equal-magnification lens array plate comprises first and second lens array plates stacked on one another, a fourth surface light-shielding wall, and an intermediate light-shielding wall. An intermediate through hole formed in the intermediate light-shielding wall is formed such that the hole diameter is progressively smaller in a tapered fashion away from the first lens array plate toward the second lens array plate. An angle of inclination θ of an interior wall surface of the intermediate through hole with respect to a optical axis is given by θ≧tan−1(D4/(Gap+L2+H4))/2 where Gap denotes a gap between the lens array plates, L2 denotes a thickness of the second lens array plate, H4 denotes a height of the fourth surface light-shielding wall, and D4 denotes a diameter of the opening of the fourth surface through hole formed in the fourth surface light-shielding wall facing the image plane.

    摘要： A miniaturized lens array for unity magnification imaging comprises a plurality of rod lenses arranged in one row. An arrangement pitch D of the rod lenses is defined to satisfy (2 m+1)·D≦2.1 mm or 2.5 mm. An angle of aperture &thgr; of the rod lens is defined to satisfy &agr;D/6×{n·cos−1(−&agr;/2/m)+(4 m2/&agr;2−1)1/2}≦&thgr;≦&agr;D/2×(4/m2/&agr;2−1)1/2. The arrangement pitch D and angle of aperture &thgr; are defined in this manner, and it is therefore possible to obtain the lens array whose difference between a total width and effective lens width is equal to or smaller than 2.1 mm or 2.5 mm.
