Abstract

To reduce the size of a device comprising a plurality of image reading means.SOLUTION: A lower image reading unit 222 comprises a light receiving unit 226 that receives reflected light from a sheet. The light receiving unit 226 is provided with a plurality of light receiving elements 226A arranged side by side in a direction orthogonal to a conveyance direction of the sheet. An upper image reading unit 221 also comprises a light receiving unit 226 that receives reflected light from the sheet. The light receiving unit 226 of the lower image reading unit 222 is located on the downstream side of an upstream side portion 81 in the conveyance direction of the sheet. The light receiving unit 226 of the upper image reading unit 221 is located on the upstream side of a downstream side portion 82 in the conveyance direction of the sheet.SELECTED DRAWING: Figure 15
