摘要： A first positioning member is provided on a document table to extend in a first scanning direction and determines a position in a second scanning direction of an edge of a document placed on the placing surface. A first reference area holding member extends from a first positioning member over the placing surface and holds, on its surface opposing the placing surface, two reference areas extending parallel to the first scanning direction and including a first and second reference areas each having a different pattern from each other. A border position in the first scanning direction between at least one of the first and second reference areas and the document is detected, based on a received light quantity of reflected light. A size determining unit calculates a document length in the first scanning direction based on the detected border position.

摘要： A fixing unit is disposed at a position closer to a rear side wall than to a front side wall of a casing. A top wall is formed with a depressed portion depressed toward inside the casing. The depressed portion serves as a sheet discharge tray for receiving a recording medium that has passed through the fixing unit. The sheet discharge tray includes a tray member detachably disposed at the top wall. The rear side wall is formed with an opening through which the fixing unit is removed. When the tray member is disposed at the top wall, the tray member is positioned above and adjacent to the fixing unit and overlaps the fixing unit when viewed through the opening, thereby preventing the fixing unit from being removed from the casing. The fixing unit is removable through the opening when the tray member is detached from the top wall.

摘要： An image processing apparatus includes an indicator display unit that displays an indicator for specifying a selection region. The selection region has a quadrilateral shape defined by a third pair of parallel sides and a fourth pair of parallel sides, which are substantially in parallel with a first pair of parallel sides and a second pair of parallel sides of an image displayed on a display screen, respectively. The indicator indicates positions of the third pair and movably displayed in parallel with the second while the parallel sides of the third pair are retained at a predetermined distance. A position of the third pair is determined in accordance with a decided position of the indicator, and a position of the fourth pair is determined to substantially coincide with the second pair of the image. Image data corresponding to the determined selection region is selected as selected image data.

摘要： An image scanner includes a transparent plate, a scanning device, a driving device, a positioning member, a light absorbing portion and a white reference portion. The transparent plate has an original placing surface. The scanning device irradiates an original with light by means of a light source and scans reflected light from the original. The driving device reciprocates the scanning device along the transparent plate. The positioning member positions the original placed on the original placing surface of the transparent plate. The light absorbing portion, which is disposed on the original placing surface side of the positioning member and at substantially a central portion of the positioning member in moving directions of the scanning device, absorbs ambient light entering to the original placing surface side of the positioning member through the transparent plate. The white reference portion is provided to the original placing surface side of the positioning member.
