    摘要： Apparatus for holding a stack of sheets for entry into a sheet feeder, wherein there is provided a tray for vertically supporting the stack, left and right guide elements moveable toward and away from the lateral edges of the stack for centering the stack in the tray, and a flexible band formed in a loop, the band being attached to the guide elements at two locations, such that the guide elements move inward and outward laterally in unison, and the band being supported beneath the tray, and wherein the band is bent (e.g., around a convex surface) during inward movement of the guide elements so that when the movement stops the band tends to move the guide elements outwardly as it assumes an equilibrium position, thereby preventing overtightening of the guide elements against the stack.

    摘要： A medium conveying apparatus includes medium conveying apparatus includes a housing including a locking portion, a first supporting portion and a second supporting portion, a feed roller, a separation roller located to face the feed roller, and a guide mechanism including a locked portion locked with the locking portion, a first shaft portion supported by the first supporting portion, a second shaft portion supported by the second supporting portion, and a conveyance guide portion to regulate a medium fed between the feed roller and the separation roller. The guide mechanism is swingably supported by the housing about the first shaft portion in a state where the locked portion is locked with the locking portion. The guide mechanism is swingably supported by the housing about the second shaft portion in a state where a locking of the locking portion and the locked portion is released.

    摘要： A feeding apparatus includes a feeding roller that comes in contact with one of stacked printing media and feeds the printing medium; a support member that supports the feeding roller; an inclined portion that is arranged downstream of the feeding roller in a feeding direction in which the printing medium is fed, the inclined portion being inclined with respect to the stacked printing media; and a restriction member that is arranged downstream of the feeding roller in the feeding direction, the restriction member being capable of coming in contact with the printing medium fed by the feeding roller. The restriction member is provided independently from the support member and is capable of moving between a first position and a second position, the first position being set adjacent to a downstream region of the inclined portion in the feeding direction, the second position being set between the first position and the feeding roller with respect to the feeding direction.
