Abstract: An image reading device includes a contact glass, a document transport device, a first reading module, a second reading module, a opposite roller, and roller holders. The opposite roller transports a document while keeping it in close contact with an image reading surface of the second reading module arranged inside the document transport device. The roller holders rotatably support the opposite roller, and on their faces facing the second reading module, a pair of patterns for detection is provided to detect the inclination of the opposite roller. The patterns for detection are each formed to be increasingly wide toward a first end side in the axial direction upstream from an intersection in a central part thereof in the document transport direction, and increasingly wide toward a second end side opposite from the first end side downward from the intersection in the document transport direction.

Abstract: An image processing portion determines that a black stripe is present when among a plurality of main scanning lines included in a back end side range from a last back end position of the reading image data in a sub-scanning direction to a predetermined position, a main scanning line in which a density value of a pixels in a predetermined position is higher than a first threshold density is present, sets, at a reference line, a main scanning line farthest from the last back end position among the main scanning lines in which the density value of the pixel in the predetermined position is higher than the first threshold density and replaces density values of all pixels included in a range from a position of the reference line in the sub-scanning direction to the last back end position with a density value corresponding to white.

Abstract: An image reading device includes a light source, an imaging element and a control unit. The light source irradiates light on a document. The irradiated light of the light source reflected by the document is incident on the imaging element. The control unit is configured to, if the document is an ordinary document having no light-emitting screen, set a light amount of the irradiated light of the light source at a predetermined reference value and is configured to, if the document is a special document having a light-emitting screen, reduce the light amount of the irradiated light of the light source to become lower than the reference value.
