ABSTRACT:
A paper cassette used in a printer for holding sheets of paper. The cassette comprises a case holding sheets of paper and corner claws mounted at both sides of the front end of this case. The claws engage the front ends of the corners of the uppermost sheet of paper. The claws have front walls which are inclined upwardly toward the direction in which the uppermost sheet is fed. 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.
