Claims

[Claims for Utility Model Registration] A reading element 2 in which a large number of photoelectric conversion elements are arranged in a linear manner so as to be approximately coextensive with the reading width of the original 1, and a large number of light emitting elements in a linear manner are arranged in approximately the same length as the reading element 2. An image sensor comprising: a light source 3 disposed on the light source 3; and an optical means 4 for forming an image of the light source 1 irradiated by the light source 3 on the reading element 2, the light source 3 having mirror surfaces at both ends. An image sensor characterized in that a mirror 6 is provided so that the mirrors 6 face each other.
