Claim:
An image sensor comprising: a light source; a light guide having a rod-like shape, providing said light source at both sides thereof, and including: a first emitting section for emitting light from an oblique direction with reference to a radiated section of a sheet of copy, with light of said light source being propagated in a main scanning direction with reflection inside thereof; and a second emitting section for emitting light in the transmitting direction of said sheet of copy; a lens body for converging light reflected from said radiated section of said sheet of copy; a sensor for receiving light passed through said lens body; a reflection body, positioned at an opposite side of said light guide with reference to said lens body, for emitting light from an oblique direction with reference to said radiated section of said sheet of copy, with light from said second emitting section being reflected such that a light path of said light emitted from said second emitting section is in between said lens body and said sheet of copy; and first and second light scattering layers respectively formed to sections facing said first and second emitting sections in said light guide, wherein light reflected by said first and second light scattering layers is emitted through said first and second emitting sections.
