A sheet feeding apparatus includes a support member having a support surface, a feed roller, a stopper, and a restriction member. The stopper includes a restriction surface configured to contact leading edges of sheets supported on the support surface. A tangent extends in parallel to the support surface and passes through a point on an outer peripheral surface of the feed roller, and the tangent and the restriction surface of the stopper crosses at an intersection point. When the stopper moves from a first position to a second position, the intersection point moves with a movement velocity in a direction parallel to the tangent, the movement velocity at the intersection point being defined as a specified movement velocity. The restriction member is configured to restrict movement of the stopper such that the specified movement velocity is greater than or equal to a circumferential velocity of the feed roller.

A sheet feeding apparatus includes an abutment part having an abutment area against which a leading edge of a sheet abuts and a moving part to move the abutment part between first and second positions. The moving part includes a link member having an engage portion to engage with a positioning portion, the link member being joined with the abutment part, and an urging member to urge the link member such that the abutment part moves toward the second position. The abutment part is retained at the first position against an urging force of the urging member in a case where the positioning portion is engaged with the engage portion of the link member.

A sheet supplying apparatus includes a cam gear to rotate about a first axis of rotation between first and second rotating positions, and an alignment member rotatable to an alignment position to block a fore-end of a sheet of a printing medium contained on a loading table, and a transport-allowing position to allow a sheet picked up by a pickup member to be transported, according to the rotating position of the cam gear. The sheet supplying apparatus includes a main gear to rotate about a second axis of rotation, a swing arm rotatable about the second axis of rotation, and first and second swing gears, supported by the swing arm, to selectively contact the cam gear according to a rotating direction of the main gear so as to rotate the cam gear between the first and second rotating positions.

A sheet feeding apparatus includes a sheet supporting portion, a feeding portion, a conveying portion configured to convey the sheet fed by the feeding portion, a separation member, a returning portion, the returning portion pushing the sheet back toward the sheet supporting portion by moving from a retracting position to a protruding position, and a pressing portion including a contact portion configured to contact the sheet. The pressing portion is configured to press the sheet from above via the contact portion such that the sheet is pushed toward the returning portion in a state where the returning portion is positioned at the protruding position and below the sheet.

A sheet supplying apparatus includes an alignment member pivotable to an alignment location for blocking and aligning fore-ends of media contained on a loading table, and a transport-allowing location for allowing a medium picked up by a pickup member to be transported, a cam gear including a gear portion partially including a tooth-omitted portion, and a cam portion for switching the alignment member between the alignment location and the transport-allowing location at first and second rotating locations, a swing arm pivotable about a same axis as a rotation axis of a main gear, and first and second swing gears supported by the swing arm to interlock with the main gear, selectively interlocking with the gear portion according to a rotating direction of the main gear, and rotating the cam gear to the first and second rotating locations.

A recording apparatus includes a feeding roller, a rear feeding unit being provided on a rear side of the apparatus, and a medium reversing unit provided below a medium support section and including a reversing roller. At least a part of a rear side of the rear feeding unit forms a medium transport path in which the medium is transported by the reversing roller, the rear feeding unit includes a driven roller configured to nip the medium with the reversing roller therebetween, and at least a part of the driven roller is located in a roller accommodating space formed on a rear side of the medium support section.

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.

A card transport device transports one or more cards while reducing failures of its feed unit in feeding the cards. A card transport device includes a support surface that supports one or more cards thereon, a feed unit facing the support surface for feeding the one or more chards, a separator located downstream from the feed unit in a transport direction, a slope connected to a downstream support end of the support surface in the transport direction and extending obliquely upward downstream in the transport direction toward the separator, and a restrictor located on the support surface. The restrictor restricts a position of an upstream end of a particular card directly supported on the support surface, out of the one or more cards, thereby positioning a downstream end of the particular card to be downstream from the feed unit in the transport direction.

A sheet supplying apparatus includes an alignment member pivotable to an alignment location for blocking and aligning fore-ends of media contained on a loading table, and a transport-allowing location for allowing a medium picked up by a pickup member to be transported, a cam gear including a gear portion partially including a tooth-omitted portion, and a cam portion for switching the alignment member between the alignment location and the transport-allowing location at first and second rotating locations, a swing arm pivotable about a same axis as a rotation axis of a main gear, and first and second swing gears supported by the swing arm to interlock with the main gear, selectively interlocking with the gear portion according to a rotating direction of the main gear, and rotating the cam gear to the first and second rotating locations.

A medium feeding device includes an imaging unit which images a medium tip end portion from a position of facing a face of the medium on a downstream side of a nipping position of the medium using a feeding unit and a separating unit; and a determining unit which determines whether or not there is transport disorder by evaluating a state of a boundary between a path member which forms a medium transport path and a medium tip end from image data obtained by the imaging unit, in which the determining unit sets a rectangular determining region including at least a part of the boundary with respect to the image data, and determines whether or not there is transport disorder based on a length of a boundary in the determining region.
