Abstract:
An image forming device includes a sheet container, an image former that forms an image on a surface of a sheet conveyed from the sheet container, and a re-conveyor that re-conveys the sheet to the image former which forms another image on an opposite surface of the sheet. The re-conveyor includes a first conveyance roller set and a second conveyance roller set that convey the sheet therebetween. The first conveyance roller set includes a first driving roller that receives a driving force and a first pinch roller that contacts the surface. The second conveyance roller set includes a second driving roller that receives the driving force and a second pinch roller that contacts the surface. The first driving roller has a greater coefficient of friction than the first pinch roller. The second pinch roller has a greater coefficient of friction than the first pinch roller.
Abstract:
An image forming apparatus includes a placement tray, an image forming unit, a drive unit, a control board, a power supply substrate, a high-voltage board, and low-voltage power supply harnesses. The placement tray holds a recording sheet thereon. The image forming unit forms an image on the recording sheet. The drive unit supplies driving force to the image forming unit. The control board controls the drive unit. The power supply substrate supplies electric power to the control board. The high-voltage board is disposed in one side of the placement tray. In the high-voltage board, voltage is generated higher than voltage in the power supply substrate. The low-voltage power supply harnesses are disposed in another side of the placement tray so as to supply electric power from the power supply substrate to the control board.
Abstract:
A sheet feeder feeds a sheet to an image forming unit. The sheet feeder can include a supply tray that holds a stack of sheets, a separation element disposed at an end of the supply tray, and configured to contact and apply a resistive force to a sheet in the stack, and a separation roller disposed facing the separation element, and configured to rotate, contact and apply a feeding force to an uppermost sheet in the stack. The sheet feeder may also include a pressing plate pivotally attached to the supply tray at an end remote from the separation element, and configured to move toward the separation element as a number of sheets in the stack decreases, and a pressure applying element that increases a contact surface pressure between the separation element and the uppermost sheet in response to the pressing plate moving toward the separation element.
Abstract:
An image reading apparatus includes a transport path through which a medium to be read is transported, an image reading section disposed in a middle of the transport path and reading an image formed on the medium to be read that is transported along the transport path, a cover member that covers the image reading section and the transport path, a pressing member in which another end is supported by the cover member to cause one end to be swingable, thereby pressing the transported medium to be read against the image reading section, a circuit board member which is disposed on the cover member, and on which a grounded electric circuit is formed, and a conductive member which electrically connects the pressing member to the electric circuit formed on the circuit board member to ground the pressing member through the electric circuit.
Abstract:
An image-forming device includes an image-forming unit, a casing and a handset cradle. The image-forming unit that forms an image on a recording medium includes a process unit that has a consumable unit. The casing accommodates the process unit. The casing has a top surface, a bottom surface, at least one side surface connecting the top surface and the bottom surface, and a cover capable of opening and closing. The cover is provided at the side surface. The process unit is detachable from the casing when the cover is opened. The handset cradle that supports a handset is disposed on or above the top surface. The handset cradle and the casing are disposed in an overlapping relation in a vertical direction orthogonal to the bottom surface.
Abstract:
A transporting apparatus has a transport path, a medium holding unit placed in an end of the transport path, the medium holding unit stackingly holding a medium transported along the transport path, and a charge removing unit disposed in the medium holding unit, the charge removing unit always butting against the medium that is stackingly held by the medium holding unit, thereby removing charges of the medium.
Abstract:
An original document tray for a scanning and printing apparatus includes original document guides for guiding an original document in the original document tray into a scanning unit by determining or regulating a widthwise position of the original document, and manual-feed sheet guides provided with the original document tray for guiding a manual-feed sheet to be supplied to a printing unit by determining a widthwise position of the manual-feed sheet. The manual-feed sheet guides can be adjusted manually in the widthwise direction. The original document guides are disposed on an original document supporting surface of the original document tray on which the original document is placed, and the manual-feed sheet guides are disposed on a side opposite the original document supporting surface. The original document guides can also be moved manually in the widthwise direction and move in conjunction with the manual-feed sheet guides.
Abstract:
An image forming device, comprising: a device main body; a sheet cassette detachably attachable to a cassette accommodation space; an image formation unit; a re-carrying unit configured to re-carry the reversed sheet-like medium to the image formation unit and is exposed to the cassette accommodation space when the sheet cassette is detached; and a driving source supplying a driving force to the re-carrying unit, and wherein: the re-carrying unit comprises a driving roller and a pinch roller; a drive coupling mechanism having a transmission path transmitting the driving force to the driving roller is provided; the drive coupling mechanism comprises an acting part that brings the transmission path to a coupled state by moving in accordance with an attaching motion of the sheet cassette and brings the transmission path to a cut off state by moving in accordance with a detaching motion of the sheet cassette.

Abstract:
An image forming device includes a sheet conveyor, an image former that forms an image on a surface of a sheet conveyed by the sheet conveyor, and a re-conveyor that re-conveys the sheet to the image former which forms another image on an opposite surface of the sheet. The re-conveyor includes a guide member including upper and lower conveyance members, a regulation member that regulates a position of the sheet, a conveyer roller set that conveys the sheet therebetween, an urger that urges a pinch roller toward a driving roller, and a roller holder disposed above the upper conveyance member. The upper conveyance member has ends which are secured independently to the lower conveyance member. The roller holder secures the pinch roller overlaps the upper conveyance member in a vertical direction, and secures the pinch roller, such that the pinch roller contacts the sheet through the upper conveyance member.
