ABSTRACT:
A light emitting array unit for emitting line-shaped light is provided. A first light emitting element array includes a first group of plural light emitting elements, for emitting a first train of spotted lights. A second light emitting element array is disposed to extend substantially in parallel with the first light emitting element array, and includes a second group of plural light emitting elements arranged alternately with the plural light emitting elements in the first group, for emitting a second train of spotted lights. A first prism element group receives incidence of the first spotted light train, and emits the first spotted light train in a predetermined direction. A second prism element group receives incidence of the second spotted light train, and emits the second spotted light train in the predetermined direction. The line-shaped light is constituted by the first and second spotted light trains and is emitted.
