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 is provided, including a platen glass having opposed upper and lower surfaces, a support frame supporting a peripheral portion of the platen glass, a reading device reciprocable in a first direction and disposed on an inner side of the support frame so as to be nearer to the lower surface than to the upper surface, a guide formed on an inner bottom surface on the inner side of the support frame and extending in the first direction so as to guide reciprocation of the reading device, a controller that controls operations of the reading device, a harness connecting the reading device and the controller to each other, and a harness accommodating portion accommodating the harness and constituted by a groove having a recessed shape, extending in the first direction, and formed at the inner bottom surface at a position located in front of the guide.

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.

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.

An image forming system (100) includes an image forming apparatus (1) and an image reading apparatus (50). The image forming apparatus (1) include a first casing (10) including a top plate (13) having a first opening (11) and a second opening (12); and a fixing member (20) disposed below the top plate (13), having a first projecting part (21) and a second projecting part (22) and operated such that the first projecting part (21) is protruded and retracted through the first opening (11) and the second projecting part (22) is protruded and retracted through the second opening (12). The image reading apparatus (50) includes: a second casing (60) placed on the first casing (10); a second carriage (52) being movable inside the second casing (60); a lock member (70) which is engaged with the second carriage (52) to restrict movement of the second carriage (52), and when pushed up by the first projecting part (21), is disengaged from the second carriage (52) to release restriction of the movement of the second carriage (52); and a third opening (64) into which the second projecting part (22).

An object of the present invention is to provide a printing apparatus including a scanner unit openable and closable with respect to a printer body unit for simultaneously achieving smooth opening/closing movement and the downsizing of the apparatus. The printing apparatus includes a first gear member provided in the printer body unit and a second gear member which is attached to the scanner unit so as to be swingable with respect to the scanner unit and which is in mesh with the first gear member. When the scanner unit opens or closes with respect to the printer body unit, the second gear member swings with respect to the scanner unit while retaining a meshing state with the first gear member.

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.

An image reading device comprises a document table having a plate-shaped transparent member for a document to be placed thereon, an image reading unit for reading the document placed on the upper surface of the transparent member from the lower surface side of the transparent member, a carriage for driving the image reading unit to move reciprocally, and a case for containing the carriage. The document table has a frame member along a periphery of the transparent member and is secured to the case by engagement right under the frame member.

An image reading apparatus includes: a platen glass having upper and lower surfaces; a support frame supporting a peripheral portion of the platen glass; a reading device reciprocable in a first direction and disposed on an inner side of the support frame so as to be nearer to the lower surface than to the upper surface; a guide formed on an inner bottom surface on the inner side of the support frame and extending in the first direction so as to guide reciprocation of the reading device; a controller that controls operations of the reading device; a harness connecting the reading device and the controller to each other; and a harness accommodating portion accommodating the harness, constituted by a groove having a recessed shape, extending in the first direction, and formed at the inner bottom surface at a position located in front of the guide.

In an example, an apparatus is described that includes a transparent platen, a substrate, an array of light sources, and a sensor. The substrate is positioned on one side of the platen and has substantially uniform reflective properties. The array of light sources is positioned on an opposite side of the platen from the substrate and includes a plurality of light sources that emits light in a visible spectrum and a light source that emits light in an invisible spectrum. The sensor is positioned on the opposite side of the platen from the substrate and detects reflected portions of the light in the visible spectrum and the light in the invisible spectrum.
