Trading card inventory management systems and related methods of use are described. These systems may include singulators, card translocators that pass cards from a receiver to storage, and back to the receiver, card chutes, and card guides. A card box system of storage and translocation is also described.

A paper feeding device includes a pickup roller mechanism disposed at an entrance of a paper feeding path, and a separation mechanism disposed to a rear end of the pickup roller mechanism. The pickup roller mechanism includes a first pickup unit positioned at the entrance of the paper feeding path, a second pickup unit mounted to a rear end of the first pickup unit, and a third pickup unit disposed to a rear end of the second pickup unit. The second pickup unit includes a first driving gear. The third pickup unit includes a second driving gear, and a transmission belt looped around an outer periphery of the first driving gear and an outer periphery of the second driving gear.

A scanner apparatus includes a housing including an insertion port into which a medium is inserted, a discharge port from which the medium is discharged, a conveying roller configured to convey the medium inserted from the scanning insertion port, and a scanning unit configured to scan the medium conveyed by the conveying roller. The scanning insertion port and the discharge port are provided on a +Y direction side of the housing. The housing includes a placement face extending in a Y direction from the scanning insertion port. The placement face, when a first end of the medium is inserted into the scanning insertion port, is able to support a portion of the medium on a second end side opposite to the first end. The first end of the medium is discharged from the discharge port in a direction on the +Y direction side or in a Z direction.

A sheet conveyor includes a feed roller configured to contact a sheet from above and feed the sheet in a sheet feed direction, a frictional member disposed downstream from the feed roller, a separation roller disposed downstream from the feed roller and facing the frictional member from above, and a guide portion located downstream from the feed roller and upstream from the separation roller. The guide portion includes a pointed portion located above a portion of a common tangent to the feed roller and the separation roller when viewed in a cross section that is orthogonal to an axial direction of the feed roller and an axial direction of the separation roller. The pointed portion is located along a width direction of the sheet. The guide portion is configured to guide the sheet fed over the pointed portion toward a nip between the separation roller and the frictional member.

A sheet conveying device includes a sheet feed tray. The sheet feed tray includes a first guide and a second guide. The first guide has a first end portion. The first end portion has a first area located in a central portion in a width direction, and a second area located closer to one end in the width direction than the first area. The first end portion is inclined such that the first area is downstream of the second area in the sheet conveying direction. The second guide has an upper end portion located downstream of the first end portion of the first guide in the sheet conveying direction and above the first end portion. The upper end portion has a third area located in a central portion in the width direction and a fourth area located closer to an end in the width direction than the third area.

A sheet conveying device includes a sheet stacker, an air blower, and a guide. The sheet stacker stacks sheets. The air blower blows air to the sheets. The guide faces an uppermost sheet on the sheet stacker. A set height of a contact portion of the guide to contact the uppermost sheet is changeable.

A sheet feeding apparatus includes an apparatus body, a drawer portion including a sheet supporting portion, a feeding portion, a conveyance portion, a first conveyance guide and a second conveyance guide forming a conveyance path through which the sheet passes, and an abutment surface disposed downstream of a sheet conveyance area of the conveyance path in the drawing direction, overlaps with the conveyance path when viewed in the drawing direction, and configured to guide the sheet toward the drawer portion in a case where the drawer portion is drawn from the apparatus body in a state where the sheet is stuck across the drawer portion and the conveyance path, the abutment surface being inclined downward as the abutment surface extends downstream in the drawing direction, the abutment surface being inclined downward as the abutment surface extends upstream in the sheet feeding direction.

A sheet conveying device includes a sheet feed tray with a first guide, a main body with a second guide, a guide member disposed at the sheet feed tray, and a contact portion located at the main body. The sheet feed tray is movable in a first direction. The guide member is movable between a protruding position and a withdrawn position. The guide member at the protruding position is disposed downstream of the first guide in a sheet conveyance direction and upstream of the second guide in the first direction such that the guide member overlaps the second guide in the first direction. The guide member at the withdrawn position does not overlap the second guide in the first direction. The contact portion is configured to, as the sheet feed tray moves from the main body, contact and move the guide member from the protruding position toward the withdrawn position.
