A medium processing device includes a conveyance guide that forms first, second and third conveyance paths that intersect, a blade configured to be rotatable around a blade center point, and that switches a conveyance route of the medium by connecting any two of the three conveyance paths with each other, and a first pair, second pair and third pair of conveyance rollers that are rotatable and are configured to hand off the medium between two conveyance paths connected by the blade. The first pair of conveyance rollers includes a first roller and a second roller. The second roller is closer than the first roller to the third pair of conveyance rollers. A radius of the second roller is larger than a radius of the first roller. A first center holding distance is different from one or both of a second center holding distance and a third center holding distance.

A sheet transport device includes a transport guide for guiding, along its transport surface, a sheet in a transport direction, a first transport roller pair, a second transport roller pair, a skew roller pair, a reference wall, and an actuator. The skew roller pair alone transports, in a skewed manner toward an end of the transport surface in a width direction orthogonal to the transport direction, the sheet spaced from the first transport roller and the second transport roller. The reference wall is positioned at the end of the transport surface in the width direction and extends along the transport direction. The actuator is disposed downstream of the skew roller pair and upstream of the second transport roller pair in the transport direction and between the end and a center of the transport surface in the width direction.

A sheet guiding device includes a cover unit, a swing guide, a link member, and a contact member. The cover unit is configured to be openably disposed on a housing of an image forming apparatus. The swing guide is configured to move between a guide position at which the swing guide is open to guide a sheet and a retracted position at which the swing guide is closed. The swing guide is configured to move from the retracted position to the guide position along with closing movement of the cover unit. The link member has one end configured to be held by the housing and an opposite end engaged with the swing guide. The contact member is disposed on the cover unit. The contact member is configured to contact the link member to rotate the link member in the closing movement of the cover unit.

A recording apparatus includes a sheet feeding device including a sheet feed tray on which a medium is mounted in an inclined orientation, a feeding roller configured to feed the medium, and a sheet feed slot that is defined by the sheet feed tray and the feeding roller i, and a recording section configured to perform recording onto the medium fed from the sheet feeding device. The recording apparatus includes a scanner unit that is disposed on a body of the recording apparatus and functions as a reading device for reading a document, and a guiding member that is inclined from a side surface of a guiding member installation section that is a side surface of the scanner unit on a sheet feed tray side in a state in which the scanner unit is closed with respect to the body of the recording apparatus.

Disclosed are methods and systems for dispensing a printed document from a printer machine with a dispensing device. For instance, a document being printed out from the printer machine may be monitored for, and a determination that a document is being printed out from the printer machine may be made based on the monitoring. The printed document may be engaged with an arm mechanism of the dispensing device, the printed document may be urged towards a slot of the dispensing device with the arm mechanism, and the printed document may be dispensed out of the slot with the arm mechanism.

An image reading apparatus includes a supporting portion, a feeding portion, a curved conveyance path, a conveyance unit, an image reading unit, a driving source, an output pulley, an input pulley, a first pulley, a second pulley, a driving belt, and a transmission belt. The image reading unit is configured to read an image on a first surface at a location between the first driving roller and the second driving roller in a sheet conveyance direction. The output pulley is fixed to an output shaft of the driving source. The input pulley is fixed to the second driving roller. The first pulley is fixed to the first driving roller. The second pulley is fixed to the second driving roller. The driving belt is wound around the output pulley and the input pulley. The transmission belt is wound around the first pulley and the second pulley.

An image reading apparatus includes a conveyance unit, an image reading unit, a driving source, a first pulley, a second pulley, and a transmission belt. The conveyance unit including a first driving roller and a second driving roller and configured to convey a sheet. The image reading unit configured to read an image on the sheet conveyed by the conveyance unit at a reading position between the first driving roller and the second driving roller in a sheet conveyance direction. The driving source configured to output a driving force for driving the first driving roller and the second driving roller. The first pulley fixed to the first driving roller. The second pulley fixed to the second driving roller. The transmission belt wound around the first pulley and the second pulley. An outer diameter of the second pulley is smaller than an outer diameter of the first pulley.

A first transport path is put into a first state capable of transporting a paper sheet when a first portion and a second portion engage with each other, and put into a second state in which the second portion is swingable with respect to the first portion about a first swing axis extending in a direction orthogonal to a first direction and horizontal when engagement between the first portion and the second portion is released. A contact portion comes into contact with the second portion, thereby engaging the second portion with the first portion when a second unit in which the first transport path is in the second state is moved in a second direction opposite to the first direction.

A sheet feeding device includes a roller pair being mutually non-separable; and a roller pair being mutually separable. The sheet feeding device temporarily stops a sheet in a registration position of the non-separable roller pair and then resumes feeding the sheet. The sheet feeding device feeds sheets such that a following sheet reaches the registration position from the separable roller pair after completion of ejection of a preceding sheet.
