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.

Image reading apparatus and image forming apparatus having inclined surface for easy document removal

A document supporting portion includes a first supporting portion and a second supporting portion. The first supporting portion has a first supporting surface that supports a document. The second supporting portion has a second supporting surface that supports the document together with the first supporting surface and provided so as to be slidable between a first position at which the second supporting portion located above the first supporting portion and a second position at which the second supporting surface supports the document together with the first supporting surface. In a state where the second supporting portion is located at the first position, the second supporting surface constitutes a portion of an upper surface of the document feeding apparatus.

An operation unit is provided on a front side of the image forming apparatus. A document feeding portion feeds a document supported by a document supporting portion in a document feeding direction from a front side of the image forming apparatus toward the rear side of the image forming apparatus. A document discharge portion discharges the document in a document discharge direction from the rear side toward the front side. The operation unit is disposed on one side with respect to an apparatus center of the image forming apparatus in a left-right direction orthogonal to a direction from the front side to the rear side. A conveyance center of the document feeding portion in the left-right direction is disposed on the other side with respect to the apparatus center in the left-right direction.

Image forming apparatus

A sheet feeding apparatus includes a feeding member, a first supporting member including a first supporting surface, and a second supporting member including a second supporting surface. The second supporting member is configured to move between a first position above the first supporting member and a second position to which the second supporting member is retracted upward from the first position. In a state where the second supporting member is positioned at the first position, the feeding member is configured to feed a first sheet supported on the first supporting surface and a second sheet supported on the second supporting surface. In a state where the second supporting member is positioned at the second position, the feeding member is configured to feed the first sheet that is supported on the first supporting surface at a position below the second supporting member.

An image reading apparatus incudes a guiding shaft extending in an axial direction; a reading portion supported by the shaft so as to be movable in the axial direction; a casing accommodating the reading portion, the casing including a first supporting portion supporting an end portion of the shaft and a second supporting portion supporting the other end portion of the shaft; and an elastically deformable bonding portion bonding the casing and the shaft with each other, the bonding portion being provided between the first supporting portion and the second supporting portion in the axial direction and between the casing and the shaft in a diametrical direction perpendicular to the axial direction. The shaft is supported by the first supporting portion, the second supporting portion and the bonding portion, without contact to the casing except for the first supporting portion and the second supporting portion.
