Patent ID: 8843051

Claim:
A medium containing cassette comprising: a container case for containing media; a stack plate movable in the container case and configured to stack the media thereon; a separator provided on the container case and configured to separate the media one by one; a feeding roller which is opposed to the separator across a medium conveying path through which the medium is conveyed; a bias member configured to bias the stack plate in a direction toward the media stacked on the stack plate, a projection extending from the stack plate and being in contact with the bias member such that the stack plate is biased by the bias member via the projection, wherein the bias member is disposed such that the distance between the bias member and the stack plate is greater than the distance between the stack plate and the separator in a direction along a plane substantially perpendicular to a bias direction of the bias member; wherein the projection extends in the direction from the stack plate to the separator, wherein the projection is provided at each widthwise end portion of the stack plate and extends in a longitudinal direction of the container case, such that the feeding roller is provided between the projections in the widthwise direction of the stack plate, and wherein the projection s and the stack plate form a unitary, single-piece structure.
