Abstract: A recording apparatus includes a feeding roller and a power transmission mechanism for transmitting a driving force to the feeding roller. The power transmission mechanism includes a one-way compound gear mechanism that integrally includes a first one-way gear mechanism which is engaged with a first gear rotating forwardly or reversely by receiving the driving force from the driving source, rotates together with the first gear in a forward direction by receiving the driving force from the first gear at the time of the forward rotation and rotates idly with respect to the first gear at the time of the reverse rotation, and a second one-way gear mechanism which rotates idly with respect to the first gear at the time of the forward rotation and rotates with the first gear in a reverse direction by receiving the driving force from the first gear during the reverse rotation.

Abstract: A recording apparatus includes a carriage that is provided with a recording head which performs recording on a recording medium and is movable in a scan direction of the recording head, a guide member that guides the carriage in the scan direction, and a gap adjusting unit that is interposed between a housing of the carriage and the guide member so as to displace the housing of the carriage in a direction in which a gap varies between the recording medium and the recording head, the gap adjusting unit being mounted on the carriage.

Abstract: A recording apparatus includes a transport unit that transports a recording medium, a recording unit, a discharge unit provided downstream from the recording unit, and a guide portion that is provided upstream from the discharge unit in a transport direction and that guides the recording medium to the discharge unit. The guide portion has a first guide section that guides the recording medium at a side end of the recording medium in a width direction that is orthogonal to the transport direction and a second guide section that guides the recording medium at a location closer to a central area of the recording medium than the first guide section.

Abstract: A recording apparatus includes a holding tray in which a second recording material can be set and a transportation driving roller that transports a first recording material and the holding tray. A front edge of the holding tray is set back from an outer edge of the second recording material set in the holding tray.

Abstract: The driving force transmission changeover mechanism has a changeover operation mode in which a state of transmission of the driving force changes and a maintenance operation mode in which the state of transmission of the driving force is maintained, the changeover operation mode being executed when the carriage moves from the dot formation area to a first changeover position within the recording head maintenance area and then to the dot formation area, and the maintenance operation mode being executed when the carriage moves from the dot formation area to a second changeover position within the recording head maintenance area and then to the dot formation area.

Abstract: A recording apparatus includes a tray in which a recording material is to be set, the tray being reciprocated between a first position where the tray is exposed to allow the recording material to be set therein and a second position shifted from the first position in a first direction, where the tray is stored; a transporting mechanism that applies transportation force for reciprocating the tray; and a transportation-force transmitting member that is connected to the tray to mediate transmission of the transportation force to the tray and is capable of increasing or decreasing a space occupied by the transportation-force transmitting member in the direction of reciprocation.

Abstract: A recording apparatus includes a recording head, a holding tray on which a first recording material is set and which is configured to be advanced and retracted in a linear path between a first position wherein it opposes the recording head and a second position wherein it is retracted from the first position, a reverse transporting portion for transporting a second recording material which is set under the second position while reversing the second recording material in a U shape, and a path forming member for guiding the reversed, another recording material to the linear path after the recording material is bypassed above the second position.
