Abstract
A paper feeding cassette includes a cassette body having a bottom wall, a front face wall disposed at a front end of the cassette body, a medium-stacking member disposed so as to be swingable about a support shaft relative to the cassette body wherein the medium-stacking member configured to have a medium thereon stacked, and a mechanism configured to move the medium-stacking member away from the bottom wall. The front face wall includes a curved portion.

A paper feeding cassette, comprising:
- a cassette body having a bottom wall;
- a medium-stacking member disposed so as to be swingable about a support shaft, as a swinging center, relative to the cassette body, the medium-stacking member having a medium-stacking surface configured to have a medium thereon stacked inside the cassette body;
- a front face wall disposed at a front portion of the cassette body and facing the medium;
- a separation pad disposed above the front face wall and used to separate individual medium sheets from the medium stacked inside the cassette body;
- and
- a mechanism configured to move the medium-stacking member that is upstream from the separation pad away from the bottom wall;
- wherein the front face wall includes a non-vertical inclined surface upwardly extending from a height that is lower than the support shaft, wherein the non-vertical inclined surface is provided lower than a center of the support shaft such that in a continuous area of the front face wall that extends both below and above a position of the front face wall that is at a same height in the direction perpendicular to the bottom wall as the height of the center of the support shaft, continuous area above the position inclines towards a same side with respect to the vertical direction relative to the bottom wall as continuous area below the position, and the support shaft is located above the medium-stacking surface in the state before the medium-stacking member moves away from the bottom wall.

- and
- a mechanism configured to move the medium-stacking member that is upstream from the separation pad away from the bottom wall;
- wherein the front face wall includes an inclined surface upwardly extending from a position closer to the bottom wall in a direction perpendicular to the bottom wall than the support shaft for the medium-stacking member, the inclined surface is provided closer to the bottom wall in the direction perpendicular to the bottom wall than a center of the support shaft, and the inclined surface extends to the front with respect to the cassette body as distance from the bottom wall increases in the upward direction such that in a continuous area of the front face wall that extends both below and above a position of the front face wall that is at a same height in the direction perpendicular to the bottom wall as the height of the center of the support shaft, the continuous area of the front face wall remains extending to the front with respect to the cassette body as distance from the bottom wall increases in the upward direction.

- the curved portion is provided closer to the bottom wall in the direction perpendicular to the bottom wall than the center of the support shaft, and
- an inner angle of the curved portion relative to the bottom wall decreases gradually from an obtuse angle relative to the bottom wall to a less obtuse angle as distance from the bottom wall increases in the upward direction such that in a continuous area of the front face wall that extends both below and above a position of the front face wall that is at a same height in the direction perpendicular to the bottom wall as the height of the center of the support shaft, the continuous area of the front face wall remains obtuse relative to the bottom wall as distance from the bottom wall increases.
