The conveyance section (130) is housed in the cover section (110) and conveys a sheet. The interposed member (170) is interposed between the cover section (110) and the casing (160). The controller (153) is housed in the casing (160) and controls the conveyance section (130). The cable (180) is connected to the controller (153), is also connected to the conveyance section (130), and transfers a control signal output by the controller (153) to the conveyance section (130). The linking member (190) is linked to the cover section (110) and is also linked to the casing (160).

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.

A hinge device for opening and closing a relatively lightweight cover, as well as office equipment using such a hinge device. A hinge device includes an attaching part attached to the office equipment side, the supporting part attached to the cover side, a hinge shaft for rotatably coupling the attaching part and the supporting part, a slider provided inside the supporting part so as to be slidable in a direction perpendicular to an axial direction of the hinge shaft, a cam portion formed on the attaching part, a cam bearing portion formed on the slider, an urging means for urging the slider toward the attaching member and bringing the cam bearing portion into a pressurized contact with the cam portion.

A printer includes a restrictor that is configured to switch between a restricted state that restricts a scanner unit from pivoting in an opening direction from a closed state in which the scanner unit is closed with respect to the casing, and a free state that allows the scanner unit to pivot in the opening direction from the closed state, and that enters the restricted state when the panel unit is set to a first orientation and enters the free state when the panel unit in the first orientation pivots by a predetermined angle to be in a second orientation.

To provide the original cover closer which can control a rotation torque accompanied with an opening and closing operation of in a simple structure, as compared to the conventional original cover closer, solution is made in that the original cover closer comprises an attaching part attached to the main body side; a supporting part, wherein its side plates are rotatably attached to the both side plates of the attaching plate via a hinge shaft, as well as the original cover is attached to the supporting part; a pressure receiving part provided between the both side plates of the attaching part; a cam slider slidably provided inside the supporting part by making its cam portion abut against the pressure receiving part; an elastic module resiliently provided between the cam slider and a free end side of said supporting part, so as to bring the cam slider into press contact with the pressure receiving part and to rotatably urge the supporting part in an opening direction of an original cover; and a brake module provided between the supporting part and the cam slider, and that the brake module consists of a plurality of friction protruding ridge portions provided on an inner wall surface of the supporting part toward the cam slider, and at least a gently-sloping upward inclined portion gradually climbing from the cam slider side is provided on each of the friction protruding ridge portions.

A scanner assembly for portably scanning documents is disclosed. The scanner assembly includes a board and a cradle assembly. The cradle assembly includes a first cradle member and second cradle member spaced from one another, coupled to the board, and configured to receive the scanner. The cradle assembly includes a support bracket disposed between and coupled to the first and second cradle members. The cradle assembly also includes a lock assembly coupled to the first cradle member and movable between a first position where the scanner is fixed to the first and second cradle members and a second position where the scanner is removable from the first and second cradle members. The first and second cradle members and the support bracket of the cradle assembly are movable along the board for allowing the scanner to scan documents disposed on the board.

A mobile device holding device comprises a basement including an inner accommodation space; a document feeding path including a scanning area, the document feeding path being disposed in said accommodation space; an input tray disposed on an upstream of the document feeding path to accommodate documents to be scanned; an output tray disposed on a downstream of the document feeding path to eject scanned documents; a document feeding unit disposed in the accommodation space for transmitting documents through the document feeding path; and a device holder disposed on the basement to fix a mobile device; wherein the device holder is moved to align the mobile device with the scanning area for capturing the image within the scanning area, and ensuring that the shooting area of the mobile device is not less than the width of documents to be scanned.
