    Patent number: 5271681
    Abstract: A paper cassette used in a printer for holding sheets of paper.

The front walls are also inclined from the front end of the uppermost toward the direction in which the walls are distant from the front end of the sheet by slow degrees toward the inside of the widthwise of the sheet. When the uppermost sheet is curled, the corners of the front end of the sheet are disengaged from the corner claws certainly.
