Patent ID: 7511868

Claim:
A multi-beam luminous source apparatus, comprising: a luminous source unit that includes a plurality of luminous sources monolithically arranged in a main scanning direction; a coupling lens configured to convert optical beams emitted from the luminous source unit into a predetermined convergence state; and a supporting member configured to support the luminous source unit and the coupling lens in one body, the supporting member comprising: a first member configured to support the coupling lens, the first member being rotatably mounted on the supporting member such that the coupling lens is adjustable about an optical axis of the optical beams emitted from the luminous source unit; and a second member configured to support the luminous source unit, the first member being tiltably secured to the second member such that an inclination of the first member in a main scanning plane is adjustable relative to the second member, and an inclination of the second member in the main scanning plane is adjustable relative to a reference plane that is perpendicular to the optical axis of the coupling lens.
