A medium conveying device includes a conveying lower face and a placing table. The conveying lower face has an introduction end and an ejection end. The conveying lower face inclines upward and extends linearly from the introduction end to the ejection end. The placing table is provided pivotally on an introduction end side and displaced between a first position and a second position to place a sheet-like conveyance target medium to be introduced from the introduction end. The placing table forms a linear conveying route when occupying the first position and forms a bent conveying route when occupying the second position.

A medium feed apparatus includes a first support face and a second support face. The first support face supports a medium fed by a feed unit that feeds medium by supporting such that the medium adopts an inclined orientation. The second support section is positioned upstream of the first support face in a feed direction, and supports the medium together with the first support face. The second support face is at a position set back from the first support face, and an angle of inclination from a lower end portion to an upper end portion of the second support face is steeper than an angle of inclination of the first support face.

A printer includes a mainframe including a front face part that has an opening through which a recording medium passes; a guide unit connected to the mainframe on a first side of the front face part; a printer mechanism unit configured to perform printing on the recording medium, and connected to the mainframe on a second side of the front face part opposite to the first side thereof; an arm unit having a first end connected to the mainframe; and a shaft unit configured to hold a roll of the recording medium, and connected to a second end of the arm unit, wherein the guide unit is configured to guide the recording medium so as to feed the recording medium to the printer mechanism unit through the opening of the front face part of the mainframe.

A sheet feeder includes a lift table, a first sheet-side restricting member, a second sheet-side restricting member, a suction conveyor, a rear-end restricting member, an upper distance-measuring sensor, a lower distance-measuring sensor, and processing circuitry. The first sheet-side restricting member and the second sheet-side restricting member restrict first ends and second ends opposite to the first ends, respectively, of sheets. The suction conveyor sucks and conveys a sheet floated. The rear-end restricting member restricts the sheets from moving in a longitudinal direction of the sheets. The upper distance-measuring sensor and the lower distance-measuring sensor measure a first distance and a second distance, respectively, to the first sheet-side restricting member or the second sheet-side restricting member. The processing circuitry compares measurement results of the first distance and the second distance to determine whether a distance between the first sheet-side restricting member and the second sheet-side restricting member is adequate.

A sheet loading apparatus for carrying a sheet loaded in a first tray to a second tray includes: a grip portion configured to grip the sheet; a sliding portion configured to move the grip portion between a sheet gripping position and a sheet release position; a lift portion configured to move the grip portion and cause the grip portion to emerge from the sheet loading surface; and a common power transmission portion configured to transmit power to both the sliding portion and the lift portion, wherein in one cycle, after the sliding portion moves the grip portion to a downstream side, the lift portion moves the grip portion downward of the sheet loading surface to cause the grip portion to reach the release position, and after the sliding portion moves the grip portion to the upstream side, the lift portion moves the grip portion to the gripping position.
