Abstract
Abstract A solid state imaging device with a plurality of line sensors in which each line sensor receives the light through the divided light paths from a straight line of a document into each unit is disclosed. The divided light paths are obtained by bending each rod lens of the rodlenses array, providing concave or convex lenses or convex mirrors or by providing transparent plates at different angles. As a result of the dividing of light path the line sensors pick up linear image data without abutting each sensor in a straight line.
