摘要： Reference images on the respective surfaces of a reference document transported on a transportation path are read out by a first image reading section and a second image reading section, respectively. As a result a first reference readout image and a second reference readout image are acquired. in accordance with the difference between the changes in the sub-scanning direction in the first reference readout image and the changes in the sub-scanning direction in the second reference readout image, the reading cycle of the first image reading section X1 and the reading cycle of the second image reading section X2 are set. This makes it possible to equalize the magnifications of the respective images on the front and back sides of the document, even if the speeds of the document at the times of passing through readout positions for the front and back sides change over time, on account of the wear of a transportation roller.

摘要： A light emitting unit comprises a light emitting element, a light emitting element substrate for mounting the light emitting element, and a light emitting element substrate frame member provided with a window for exposing the light emitting element, wherein the inside of the window is sealed with a first resin and a second resin, the ratio of the second resin relative to the first resin becomes smaller toward the outside of the window from the inside thereof. The first resin is a transparent resin, and the second resin is a colored resin with a high color value or a resin including a light reflective material and/or a light scattering material. Since a sectional border line between the first resin and the second resin is a curved line, the light reflected from the bottom section of the window among the light emitted from the light emitting element can also be efficiently emitted to the outside.
