An optical scanning device includes a housing and an fθ lens accommodated in the housing. The housing has a bottom surface, and side walls erected from a bottom surface and surrounding the bottom surface along a perimeter thereof. One side wall of the side walls has, on an outer surface thereof, one or more positioners that position the optical scanning device relative to an image forming apparatus main body. The bottom surface has one or more first bottom surface ribs extending from the positioners toward the fθ lens in an oblique direction with respect to the side wall having the positioners in a plan view.

A reading apparatus, having a document tray, an ejection tray, a conveyer path connecting the document tray and the ejection tray and having a curved section, a conveyer to convey an original document in a conveying orientation, a first reading sensor, and a second reading sensor, is provided. The first reading sensor is located upstream in the conveying orientation from the curved section in the conveyer path. The first reading sensor optically reads a first side of the original document from below. The second reading sensor is located upstream in the conveying orientation from the first reading sensor in the conveyer path. The second reading sensor optically reads a second side of the original document from below. The first side and the second side are sides of the original document that face upward and downward, respectively, in the state where an original document is placed on the document tray.

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.

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 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.

A scanner includes a lower unit and an upper unit. The lower unit includes a first document table on which a first document is to be placed. The upper unit includes a second document table on which a second document is to be loaded and a document feed path through which the second document is to be picked up from the second document table fed, the upper unit being coupled to the lower unit to pivot between a closed position in which the first document table is covered and an open position in which the first document table is exposed. The upper unit further includes a reading unit to read an image from the first document and the second document by performing flatbed scanning on the first document and document feed scanning on the second document.

An image reading apparatus includes a reading controller, a data generating circuit unit, a document holder, an opening/closing sensor which provides an output of a first level when the document holder is open by an angle equal to or more than a predetermined angle, and a storage unit which stores an adjustment value. Where a return is made from a power saving mode to an active mode, when an output level of the opening/closing sensor is the first level, the reading controller makes a setting for an operation of the data generating circuit unit based on the adjustment value stored in the storage unit, and then makes the reading unit perform reading for document size detection.

A reading apparatus includes: a document platen on which a document is placed; a reading portion configured to read a document placed on the document platen; a cover that is openable and closable between a first position at which the document platen is covered and a second position at which the document is uncovered; and a frame member including a first inclination portion and a second inclination portion, configured to constitute at least a part of an outer frame of the document platen, the first inclination portion being adjacent to the document platen and higher with an increasing distance from the document platen, and the second inclination portion being arranged farther away from the document platen than the first inclination portion and higher with an increasing distance from the document platen.

Example media scanning assemblies are disclosed. In an example, the media scanning assembly includes a media feeder assembly including an output tray, an input tray disposed vertically lower than the output tray, and a first scanning device. In addition, the media scanning assembly includes a flatbed scanning assembly coupled to the media scanning assembly. The flatbed scanning assembly includes a transparent platen and a second scanning device to move relative to the platen. The media feeder assembly includes a media path extending from the input tray, across a portion of the platen, to the output tray, and the media feeder assembly is to advance media along the media path from the input tray to the output tray so that the first scanning device is to scan a first side of the media and the second scanning device is to scan a second side of the media through the platen.

An image reading apparatus includes a platen on which a document is to be placed, an image sensor configured to read an image of the document on the platen, an opening/closing member configured to cover and uncover the platen, a document pressing layer disposed on a surface of the opening/closing member and configured to press the document on the plate when the opening/closing member covers the platen, elastic layers located between the document pressing layer and the opening/closing member and spaced apart from each other on a surface of the document pressing layer, and connection layers connecting the elastic layers to the opening/closing member. An area of the elastic layer is larger than an area of the connection layer.
