<p>PURPOSE:To enhance the printing quality by compact apparatus constitution by forming a non-reflecting coating layer for preventing the reflection of the incident light from an LED to the incident surface of a condensing lens. CONSTITUTION:A non-reflecting coating layer 28 is provided to the incident surface of a SELFOC lens array 27. Since the reflectivity of the incident surface of the SELFOC lens array 127 to the light emitted from an LED becomes 0 by said coating layer 28, flare light can be perfectly cut. As a result, the printing quality of an LED printer can be enhanced markedly by merely forming the coating layer to the part corresponding to the incident surface of a condensing lens and, therefore, the complication of apparatus constitution and an increase of the number of parts can be avoided.</p> |
