A sheet conveying apparatus includes first and second drive sources, first and second driving units, each including a respective first or second roller to convey a sheet, an operating unit, and a switching unit to switch a state of the sheet conveying apparatus between a first state in which the first driving unit and the second driving unit are not connected to each other and a second state in which the first driving unit and the second driving unit are connected to each other. A first drive source driving force drives the first driving unit. A second drive source driving force drives the second driving unit. The operating unit rotates when manually operated. In the second state, operating unit rotation is transmitted to the first driving unit to rotate the first roller, and operating unit rotation is transmitted to the second driving unit to rotate the second roller.

A medium processing apparatus includes a processing section performing a process on a sheet-like medium; a transport roller pair including a driving roller and a driven roller, and transporting the medium in a transport path including a region in which the processing section performs a process; a first casing accommodating the processing section and the transport roller pair; a second casing configured to close and open with respect to the first casing; and a displacement mechanism displacing the transport roller pair to a separation position and a contact position. The displacement mechanism displaces the transport roller pair from the contact position to the separation position in conjunction with an operation of opening the second casing.

A liquid discharge apparatus includes a liquid discharge head, a stage, a guide rail, and an opening-and-closing cover. The liquid discharge head discharges a liquid to a recording medium. The stage moves in a vertical direction to move the recording medium on the stage. The guide rail holds the stage. The stage is movable in a conveyance direction intersecting the vertical direction. The opening-and-closing cover is slidable in one of the conveyance direction and a main scanning direction intersecting both the conveyance direction and the vertical direction. The opening-and-closing cover includes a retraction portion retractable above the stage.

A sheet conveyance apparatus includes an apparatus body including a first guide configured to form a conveyance path along which a sheet to be conveyed is guided, an opening/closing member including a second guide disposed opposite the first guide and configured to form the conveyance path, the opening/closing member being openable and closable with respect to the apparatus body around a rotation axis, a light source configured to emit light, and a reflection unit configured to reflect light from the light source. The light source and the reflection unit are disposed such that, in an open state where the opening/closing member is open to expose the conveyance path, the first guide is irradiated, in a direction from a side farther from the rotation axis to a side closer to the rotation axis, with the light reflected by the reflection unit.

A sheet feeding device includes a detachable separation unit, a conveyance unit, a guide member, an urging member, and an opening and closing member. The feeding unit feeds a stored sheet. The separation unit separates sheets fed by the feeding unit one by one. The conveyance unit conveys the sheet. Urged by the urging member, the guide member guides the sheet toward the conveyance unit and rotates about a first rotating shaft. The opening and closing member opens and closes. In a state in which the opening and closing member is closed, the guide member is positioned in a first position in which the guide member forms a conveyance path. In a process in which the opening and closing member is opened, a free end of the guide member moves upwardly about the first rotating shaft, by using an urging force, from the first to a second position.

A bag dispensing system for dispensing bags one at a time includes a plurality of bags detachably coupled end-to-end. A box defines a chamber which contains the plurality of bags. A front wall of the box extends between a pair of side walls of the box and upwardly from a bottom wall. An upper edge of the top wall is positioned spaced from the top wall, defining an aperture. The aperture has a width and a height greater than a width and a height respectively of the plurality of the bags so that the plurality of bags is insertable into the chamber through the aperture. A door is movably coupled to the front wall between an open position, thereby opening and closing the aperture respectively. A bag slot extends the door which receives an end bag of the plurality of bags therethrough.

A feeding device includes a loading unit at which a printing medium is loaded, a roller that transports the printing medium, a transport path member at which the roller is disposed, the transport path member constituting a transport path on which the printing medium is transported, a drive source that generates a drive force that rotates the roller, a clutch that is movable between a coupling position at which the drive force is transmitted to the roller, and a release position at which the drive force is not transmitted to the roller, and an operation unit for operating the clutch, in which the operation unit is provided at a position, on the transport path member, facing the printing medium being transported by the roller, and the roller is removable from the transport path member when the clutch is located at the release position.

A sheet feeding device includes a feeding roller pair, a first guide, a door including a second guide and rotatable between a first direction and a second direction opposite to the first direction through first to third positions, a damping mechanism, and an engaging portion including an elastic member. A first resisting force is set so that moment acting around a shaft by a self-weight of the door is larger than the first resisting force of the damping mechanism when the door is positioned between the second position and the third position. A resultant force of the first resisting force of the damping mechanism and a second resisting force of the elastic portion is set so that the moment acting around the shaft by the self-weight of the door is larger than the resultant force when the door is positioned between the second position and the third position.

A medium-transport apparatus includes: an apparatus main body having the transport path for transporting the medium; and a cover CV provided on the side surface of the apparatus main body and configured to be switched between a first state of exposing the transport path and a second state of covering the transport path. The cover CV is divided into: a first cover that has the rotation shaft along a Z-axis and is rotatable with respect to the apparatus main body; and a second cover that is arranged on a Z side of the first cover, has the rotation shaft along a Y-axis on the Z-side, and is rotatable with respect to the apparatus main body.

An image forming device includes a case whereon a medium gateway opening is formed, and a tray assembly. The tray assembly includes a tray, a cover and a resilient component. The tray drives the cover to pivot relative to the case in a first pivoting direction from a second folding position to a second using position to reveal the medium gateway opening when the tray pivots relative to the case in the first pivoting direction from a first folding position to a first using position. When the tray pivots relative to the case in a second pivoting direction opposite to the first pivoting direction from the first using position to the first folding position, the cover is driven by the resilient component to pivot relative to the case in the second pivoting direction from the second using position to the second folding position to conceal the medium gateway opening.
