Abstract
A paper tray for a printing device is disclosed having a pair of paper supporting members, movable relative to one another, for supporting the lateral sides of a stack of individual sheets of paper. The movability of the paper supporting members relative to one another allows the paper tray to accommodate stacks of individual sheets of paper having different widths or size. The paper supporting members are provided with a concave paper supporting surface such that the stack of individual sheets of paper assumes a concave shape, thereby having sufficient mechanical strength to be self-supporting in the unsupported region between the paper supporting members. The curved shape of the stack is provided, in part, by a forwardly arranged paper pressing plate which is rotatable about an axis spaced from the rotational axis of a control rod which is adapted for rotating the paper pressing plate into a position for replenishing the individual sheets of paper within the stack. As the stack is depleted, the paper pressing plate maintains engagement of the top sheet of paper within the stack with a pair of spaced apart paper feed rollers, whose operation supplies the top sheet to the platen of the printing device.
