An image reading apparatus includes a reading unit, a cover, and a hinge mechanism connecting the cover to the reading unit pivotably about a pivot axis which extends in a first direction. A center of gravity of the cover is closer to a first end of the cover in a first direction than to a second end of the cover. A first hinge is spaced from the center of gravity toward the second end of the cover in the first direction. A second hinge is disposed closer to the center of gravity in the first direction than the first hinge. The first hinge includes a base member disposed movably in the reading unit, a pivot member coupled to the cover, and an urging member exerting an urging force between the base member and the pivot member so as to maintain the cover at a pivoted position.

An image forming device, which is included in an image forming apparatus, includes an image reader, a sheet conveyance passage, a transparent body, an opposing body, and multiple curved opposing portions. The image reader is configured to read an image formed on a target object. The sheet conveyance passage is a passage through which the target object is conveyed. The transparent body is disposed between the sheet conveyance passage and the image reader. The opposing body is disposed facing the transparent body on a side opposite the image reader. The multiple curved opposing portions have respective outwardly curving reference planes. The multiple curved opposing portions are sequentially switched and located at a predetermined image reading position at which the multiple curved opposing portions face the transparent body with a gap through which the target object passes the predetermined image reading position.

An image reading apparatus includes a transparent member including a document placing surface on which a document is placed, a document pressing portion that presses the document placed on the transparent member against the transparent member, a pivot supporting portion that pivotably supports the document pressing portion so as to be pivotable about a pivot shaft with respect to a casing of the image reading apparatus, an image reading unit, an abutment portion against which an edge portion of the document placed on the document placing surface is abutted in order to position the document at a reference position, and an inclined surface. The abutment portion is provided at one portion of a front end on a side far from the pivot supporting portion. The inclined surface is provided at another portion of the front end and inclined upward toward the side far from the pivot supporting portion.

An image reading apparatus includes a conveyance unit, a casing, a reading unit, a support shaft, a first cable, and a second cable. The reading unit includes a reading sensor configured to read an image of the sheet conveyed in the conveyance path through the transparent member. The support shaft supports the reading unit in a manner of moving in a moving direction orthogonal to a longitudinal direction of the reading unit. The first cable is connected to a first connecting portion disposed in the reading unit, the first cable being held by the reading unit on one side in the longitudinal direction with respect to the support shaft. The second cable is connected to a second connecting portion disposed in the reading unit, the second cable being held by the reading unit on the other side in the longitudinal direction with respect to the support shaft.

A document reading apparatus includes an image reading unit, a document conveyance unit, and a hinge mechanism. The document conveyance unit includes a first abutment portion and a second abutment portion. The document conveyance unit includes a first abutment portion and a second abutment portion. The hinge mechanism includes a first member, a first shaft, a second member, a second shaft, a third member, a third shaft, a fourth member, a first urging portion, a second urging portion. The fourth member has a first pair of side plates supported by the third shaft. The second spring is disposed outside the first pair of side plates in an axial direction of the third shaft.

An image reading apparatus includes a transparent member including a document placing surface on which a document is placed, a document pressing portion that presses the document placed on the transparent member against the transparent member, a pivot supporting portion that pivotably supports the document pressing portion so as to be pivotable about a pivot shaft with respect to a casing of the image reading apparatus, an image reading unit, an abutment portion against which an edge portion of the document placed on the document placing surface is abutted in order to position the document at a reference position, and an inclined surface. The abutment portion is provided at one portion of a front end on a side far from the pivot supporting portion. The inclined surface is provided at another portion of the front end and inclined upward toward the side far from the pivot supporting portion.

Provided is an image reading apparatus including a first image reading unit which reads a surface of a medium which is transported along a transport path; a second image reading unit which reads a surface of the medium once the medium is mounted on a medium reading surface; and an opening/closing member switch between a closed position and an opened position with respect to the medium reading surface, in which at least a part of the medium reading surface overlaps at least a part of the first image reading unit in an apparatus height direction. In addition, at least a part of the opening/closing member overlaps at least a part of the first image reading unit in the apparatus height direction.

An image reading apparatus including a conveyance portion configured to convey a document in a conveyance path, and a reading portion configured to read an image of a document conveyed in the conveyance path. The reading portion includes an image sensor configured to read an image of a document, a casing accommodating the reading element and including an opening portion having an opening through which an optical path of the reading element extends toward the conveyance path, a transparent member fixed to the casing and covering the opening, and a shield member disposed between the transparent member and the casing, and electrically grounded.

An image reading apparatus includes an image reading part that reads an image formed on a recording medium, an accommodating unit that accommodates the image reading part and supports the image reading part in such a manner that the image reading part is capable of being displaced toward a side on which the recording medium is to be disposed, and an urging member that urges, in the accommodating unit, the image reading part toward the side on which the recording medium is to be disposed. The accommodating unit includes an urging-member-mounting portion in which the urging member is mounted, and at least one window is formed in the urging-member-mounting portion on a side opposite to a side on which the image reading part is disposed.
