An image reading apparatus includes a platen, a copyholder pressed against a reading surface of a document placed on the platen, and a placing part movably provided, on which a non-pressed portion of the document that is not pressed by the copyholder is placed.

A flatbed scanner includes a flatbed document scanner body accommodating a transparent plate for supporting a physical document and a document cover, which includes a sheet member with an expanse covering at least a substantial area of the transparent plate. The rectangular document cover has an underside and a movable carriage extending across the rectangular transparent plate in a transverse direction. The movable carriage carries a camera or an optical system for a camera. The sheet member of the rectangular document cover is magnetic or carries one or more magnetic plates, so as to be magnetically attracted towards the movable carriage and exert a pressing force on the physical document when supported on the rectangular transparent plate. A compressing force is thereby applied to an original document resting at an area at which the movable carriage currently is located while scanning a line of the original document.

A flatbed scanner document scanner includes a large format document scanner body accommodating a rectangular rigid frame with an upwardly facing plane face and a rectangular transparent plate for supporting a large format document. The rectangular transparent plate overlies the upwardly facing plane face all around the metal frame. The scanner also includes a movable carriage configured to move along and below the rectangular transparent plate and carrying a line camera extending across the rectangular transparent plate. The rectangular transparent plate and the metal frame are bonded together by a hard glue seam that runs on the upwardly facing plane face of the metal frame. A predetermined deflected shape can be formed when the bonded plate and frame are turned upside-down. The rectangular metal frame can deform under its own load to a cambered shape, a flat shape or a less deflected shape when turned upright in a normal position.

An image reading device includes an angle restriction part 212a that restricts an inclination angle with respect to a document table glass (203) when viewed from a sub-scanning direction of a flat cable (214) such that a contact portion is biased to one side of the flat cable (214) in a main scanning direction when an upper surface part of the flat cable (214) contacts with the document table glass (203) with movement of an image reading unit (210).

An image reading device, which is included in an image forming apparatus, includes a first transparent body, a second transparent body, a holding body, and a reading body. The second transparent body is disposed separated from and inclined at a predetermined angle to the first transparent body. The holding body holds the first and second transparent bodies. The reading body moves in a sub-scanning direction along the first and second transparent bodies. The holding body includes a flat face and a frame-shaped face. The flat face is contiguous to the first transparent body on a same plane and smoothly connected with the second transparent body. The frame-shaped face projects outwardly beyond the second transparent body facing the reading body. The reading body moves and contacts the first transparent body and the holding body, and moves with a gap relative to the second transparent body.

An image reading device includes a contact plate, a frame, a carriage, and a flexible flat cable. The carriage includes a reading mechanism and a resin-made slider projectedly provided at both end portions of the reading mechanism in its extending direction, and reciprocally moves in a sub-scanning direction at a bottom surface side of the contact plate while the slider slides the bottom surface of the contact plate in the frame. The flexible flat cable is connected to an one side surface of the carriage so that a width direction thereof matches the main-scanning direction, is arranged so that a part continued from a portion where the flexible flat cable connects with the one side surface is curved in a U-shape to go around toward an underside of the carriage, and transmits an electric signal of the reading mechanism. The contact plate is applied with a fluorine coating.

A controller of an image reading apparatus is configured to cause the reading device to read an image on an original with moving a reading location from a first position to a second position, after reading the image on the original with moving the reading location from a third position to the first position, the third position being a position between the first position and the second position and spaced from the first position by a particular distance and determining a width of the original in the main scanning direction. The controller is configured to further move the reading location from the second position to the first position, and detect an instruction to continue reading a subsequent original during a period before the reading location reaches the third position. When the instruction is detected, the controller stops moving the reading location when it reaches the third position.

An image reading device includes first and second image reading platforms that are separated from each other with a separation member, an image reading element movable between positions facing the first and second image reading platforms, a pair of sliding members that is slideable in a direction according to the movement of the image reading element on a pair of sliding paths that extends in the direction and is disposed so as to be spaced apart from each other in another direction intersecting with the direction and that is provided so as to at least partially overlap with the first and second image reading platforms; and a pair of protrusions disposed on parts of the pair of sliding paths positioned on both sides of the separation member in the another direction and that protrudes further toward the pair of sliding members from the first and second image reading platforms.

An image reading apparatus includes a first transparent plate that supports an original document, a second transparent plate that is disposed adjacent to the first transparent plate, a reading member that moves along the first transparent plate to read an image of the original document supported by the first transparent plate and is disposed on a lower side of the second transparent plate, a positioning member that positions the reading member with respect to the second transparent plate in a plate thickness direction of the second transparent plate in a state where the reading member is disposed on the lower side of the second transparent plate, and a transporting member that transports an image of an original document to be read by the reading member positioned with respect to the second transparent plate by the first positioning member, in a linear shape along the second transparent plate.

An image display device according to the embodiment includes a display screen which is arranged on one surface of a housing and displays a page image using a display mechanism in which scanning can be optically performed in a copy machine; and a control unit which switches a page image displayed on the display screen among the plurality of page images set as a scanning target according to an operation input of a user with respect to an operation input unit which is arranged on the other surface of the housing.
