CONSTITUTION:Light emitted from the linear opening section 5a of a linear light source 5 is introduced to an optical shutter array 4 through a glass plate 7. The amount of light projected to the optical shutter array 14 can be increased by selecting the shape and position of the glass plate 7.</p> |
