Abstract: A recording apparatus includes a drive source, a medium receiving tray, a clutch, and a load applying unit. The medium receiving tray is configured to be driven by the drive source that is a motor having a cogging torque. The clutch is configured to idle when a predetermined amount of torque or more is applied, and provided to a power transmission pathway between the drive source and the medium receiving tray. The load applying unit is configured to apply a rotational load to a rotational body in the power transmission pathway closer to a side of the drive source than the clutch. The rotational load applied to the rotational body is set to a magnitude causing the clutch to idle before a rotational shaft of the motor rotates against the cogging torque when the medium receiving tray is operated by applying an external force to the medium receiving tray.

Abstract: There is provided a recording apparatus including: a recording unit that performs recording on a medium transported in a first direction; a medium feeding unit that is positioned in a second direction opposite to the first direction of the recording unit, includes a medium supporting unit; and a medium reversing unit that reverses the medium transmitted in the second direction after the recording of the recording unit, and transmits the medium to the first direction, in which the medium feeding unit includes a first guide unit and forms a first guide surface in the downward slope toward the first direction, and a power transmission unit that transmits a driving power from a power source of the medium reversing unit to the medium reversing unit, and at least a part of the first guide unit in a vertical direction overlaps with the power transmission unit.

Abstract: A recording apparatus includes a return member switchable between a first orientation in which a portion of the return member overlaps a feed roller in a side view of a medium feeding path and a second orientation in which the return member is turned toward a downstream side in a medium feeding direction and does not overlap the feed roller. The return member changes an orientation thereof from the second orientation to the first orientation, thereby returning a medium to an upstream side in the medium feeding direction. When a transport roller disposed downstream of the feed roller is driven in reverse to return the medium to the upstream side and position the medium at a recording start position, the return member takes a third orientation in which the return member is raised toward the upstream side further than in the first orientation.
