Document Type and Number:
Japanese Patent JP5840158
Kind Code:
B2
Abstract:
An image reading apparatus includes a document table, an image reading portion, a cover member, a reading control portion, and a document determination portion. On a color reference surface of the cover member which opposes to a document table, a partial region is provided which has a predetermined density different from a density of the color reference surface. The reading control portion reads image data from the color reference surface and the partial region of the cover member by the image reading portion. When a density difference between a density of the color reference surface and a density of the partial region on the image data read by the reading control portion is equal to or smaller than a predetermined threshold value, the document determination portion determines that the document placed on the document placement surface is a book document.
