Claims (1)
してライン状の光を対象物に照射する光学ヘツド
において、レンズアレイの透光面のアレイ方向と
直交する両側縁部を遮光する遮光部材を発光素子
アレイから対象物に至る光路上に配置したことを
特徴とする光学ヘツド。 In an optical head that arranges a lens array on the optical axis of a light emitting element array and irradiates a target object with line-shaped light, a light shielding member that blocks light from both edges of the transparent surface of the lens array perpendicular to the array direction is used. An optical head characterized in that it is arranged on an optical path leading from an element array to an object.
