A multifunction device includes a scanner and a printer disposed below the scanner. The scanner includes a support surface configured to support a document, and a scanning unit configured to scan the document supported by the support surface. The scanning unit includes a sensor including a plurality of reading elements arranged in a main scanning direction, and a moving member holding the sensor and configured to move in a sub-scanning direction. The scanner is connected to the printer pivotably, about a first axis extending in a first direction, between a first position at which the scanner conceals an upper portion of the printer, and a second position at which the scanner exposes the upper portion of the printer. In response to the moving member moving in the sub-scanning direction, a responsive mechanism shifts the lock mechanism between an operative state in which the lock mechanism restricts pivoting of the scanner relative to the printer, and an inoperative state in which the lock mechanism permits pivoting of the scanner relative to the printer.

A first hinge connects a scanner to a printer, which is below the scanner, to allow the scanner to pivot about a first axis extending along a first direction. The first hinge includes a first support portion supported by the scanner, a second support portion supported by the printer, and a first pivot portion defining the first axis. A housing of the scanner includes a side surface near the first axis and extending along the first direction and along a second direction perpendicular to a document support surface of the scanner, and an accommodating portion recessed in a third direction which is from the side surface toward the scanning unit. The first support portion includes a first end portion at which the first pivot portion is located, and a second end portion which includes an accommodated portion. The accommodated portion is accommodated in the accommodating portion of the housing.

An image forming apparatus (10) includes an apparatus main body (20), a first processing unit (30) and a second processing unit (40). The apparatus main body (20) performs an image forming process onto a paper sheet. The first processing unit (30) and the second processing unit (40) are disposed in vertical direction (91) such that one is located on an upside of the other on a same side face's side of the apparatus main body 20. The second processing unit (40) is disposed on the upside of the first processing unit (30), and is configured in such a manner as to be capable of being slidingly moved in an approaching-leaving direction (92) in relation to the apparatus main body (20).

An image forming apparatus, having an image forming unit, a document reader unit pivotable on the image forming unit through a hinge, a retainer to retain the document reader unit in the open position, is provided. The retainer includes a first link member rotatably coupled with the image forming unit and the document reader unit through a first coupling section and a second coupling section; a second link member rotatably coupled with the image forming unit and the document reader unit through a third coupling section and a fourth coupling section; and a tension coil spring. The first link member includes a first contacting part that faces and contacts the second link member along a tensile direction of the tension coil spring when the document reader unit is in a closed position.

A hinge structure includes an attachment recessed part, an attachment member, a first rotating body and a second rotating body. The attachment recessed part is configured to have inlet and outlet part in an upper part thereof. The attachment member is configured so that an upper end part thereof is pivotably connected to the document cover. The first rotating body is configured to be provided in the apparatus main body so as to come into contact with a side of the document mounting surface of the attachment member in the inlet and outlet part in the attachment recessed part. The second rotating body is configured to be provided in a lower part of the attachment member so as to come into contact with the attachment recessed part at an opposite side of the position in which the first rotating body is provided.

In an image forming apparatus, when a pivot plate is at a closed position, a free end of the pivot plate is at a vertical level higher than first and second hinge portions which are arranged apart from each other in a width direction along a horizontal direction. A free end of the pivot plate moves in a space defined between first and second virtual vertical planes. The first virtual vertical plane is defined as a virtual vertical plane, on which a widthwise inner end of a first hinge portion is disposed, and which is perpendicular to a rotational center axis of the first hinge portion. The second virtual vertical plane is defined as a virtual vertical plane, on which a widthwise inner end of the second hinge portion is disposed, and which is perpendicular to a rotational center axis of the second hinge portion.

A base portion includes a cam surface formed around a support pin. A turning portion includes: a slide member provided movably in directions toward and away from the support pin; and a coil spring urging the slide member. The slide member is designed to slide on the cam surface while turning, together with an openable body, about the support pin. The cam surface includes a first sliding surface, a second sliding surface, and a third sliding surface. The first sliding surface presses the slide member back in a direction of closing of the openable body. The second sliding surface presses the slide member back in a direction of opening of the openable body. The third sliding surface presses the slide member back in the direction of closing of the openable body.

A print device includes a housing, a lid body, an input device, and a mounting portion. An opening is formed in an upper portion of the housing. The lid body opens and closes the opening of the housing by a second end portion side of the lid body pivoting around a predetermined rotation axis provided at a first end portion of the lid body. The mounting portion is provided on an upper portion of the lid body when the opening is closed. The input device can be attached to and detached from the mounting portion along a predetermined attachment/detachment direction with respect to the lid body. The attachment/detachment direction is orthogonal to an extending direction of a tangent line. The tangent line is tangential to a circumferential direction of the rotation axis at a position of the second end portion of the lid body.

A hinge apparatus for a cover of an image forming apparatus has a hinge body with supporting brackets, movably inserted into a coupling hole positioned in a main body of the image forming apparatus, a hinge cam connected to the cover and pivotably connected to the supporting brackets, and a pressure device disposed at the hinge body to press the hinge cam. Accordingly, the hinge apparatus can be implemented with a simple and easy assembly operation, since it is not a complicated structural connection among the component parts of the hinge apparatus.

An image reading apparatus includes: an image reading portion configured to read an image on a sheet; a sheet feeding portion configured to feed the sheet to the image reading portion; a rotatably connecting portion which rotatably connects the sheet feeding portion to the image reading portion; a fixing member; a first fastening member configured to fasten the fixing member to a frame of the sheet feeding portion; and a second fastening member configured to fasten the fixing member to the rotatably connecting portion in a state where the frame is nipped between the rotatably connecting portion and the fixing member, wherein in case the fastening of the first fastening member is released and the fastening of the second fastening member is released, the fixing member is detachable from the frame and the rotatably connecting portion.
