<p>PURPOSE:To control an optical axis of a light beam from an LED array so that focusing can be executed, by providing an adjusting mechanism for adjusting a relation position of a selfoc lens array to a photosensitive body and executing a direction control of an optical axis of the selfoc lens array. CONSTITUTION:In case when an error exists in the accuracy of a fitting position and an attitude, etc. of a selfoc lens array 2, a position in the horizontal direction to a photosensitive body 5 of the selfoc lens array 2 is adjusted by the adjusting screws 41, 42 in the vertical direction, and also, its right and left directions are adjusted by using adjusting screws 43, 45 of one side and adjusting screws 44, 46 of the other side. Moreover, an inclination against the diameter direction of the photosensitive body 5 is adjusted by the projection quantity of the adjusting screws 43, 44 and 45, 46 positioned in the vertical direction. In such a way, by controlling an optical axis reaching the surface of the photosensitive body 5 through the selfoc lens array 2 from an LED array 1, a light beam from the LED array 1 can be adjusted so as to be radiated by adjusting a focus on the surface of the photosensitive body 5.</p> |
