摘要： A recording-material-feeding device includes a stacking portion that holds a stack of recording materials, a lifting member that moves the stacking portion up and down between a feeding position at which a recording material is fed and a refilling position at which refill recording materials are supplied, a suction member that draws one or more recording materials by suction with a negative pressure, a negative-pressure-generating member that generates the negative pressure, and a stopping member that stops an edge of the stack of recording materials on the stacking portion and includes a sealing member that maintains the level of the negative pressure. The sealing member moves up and down between a retracted position at which refill recording materials are supplied and a sealing position at which the level of the negative pressure is maintained, the sealing member moving with the up-and-down movement of the stacking portion.

摘要： A medium feeding device includes a medium-accommodating container, a loading member supported within the container and loading a medium thereon, a holding member, and a blocking unit. The holding member has a holding member body, gas suction openings, a peripheral member, a chamber surrounded by the peripheral member, and a suction unit connected to the gas suction openings and performing gas suction. The holding member holds the medium by suction. The gas suction openings include a gas suction opening disposed inside an edge of the peripheral member and outside an edge of the medium. The blocking unit blocks the suction of gas through the aforementioned gas suction opening.

摘要： A medium feed device includes a suction member that sucks a medium on a stack member; a surrounding member supported movably in directions toward and away from the stack member together with the medium by suction; a stack-member moving mechanism; a suction-member moving mechanism; a transport member that transports the medium; a detected part associated with the surrounding member; a detecting part that is supported at the suction-member body and detects the detected part; a detector that detects a medium surface position based on a detection result of the detected part detected by the detecting part if the surrounding member moves toward the suction-member body from a state in which the medium contacts the surrounding member. The stack-member moving mechanism moves the stack member based on the medium surface position.
