    Abstract: A light source position adjusting method and system are used for an image input apparatus including a light source for irradiating film original. A light source moving device is operable from the outside of the external cover of the image input apparatus. A position of the light source is adjusted from the outside of the external cover using a measuring tool so that the quantities of light are uniformly balanced at a plurality of measuring points on the plane of the film original. The measuring tool is thereafter removed. The average value of the output values in the specific pixel regions of the image sensor corresponding to the plurality of measuring points on the plane of the film original are determined and the balance output values of the respective pixel regions are stored. The position of the light source is adjusted so that the output values of the image of the light source are made equal or closer to the balanced output values stored.

    Abstract: A image reading apparatus includes a plurality of point light sources, arranged in a straight line state, configured to output light for lighting a document situated on a contact glass from a lower side of the contact glass, a light leading member, positioned in front in a light outputting direction of the light output from the point light sources, configured to lead the light output from the point light sources so as to irradiate along a main scanning direction toward the document situated on the contact glass, and a photoelectric conversion element configured to receive reflection light from the document. The light leading member includes positioning means configured to make a gap between each of the point light sources arranged in a line state and the light leading member constant and make an arrangement direction of the point light sources be positioned along a longitudinal direction of the light leading member.
