Claims20
A printing paper protecting device comprising:
- a paper cassette for holding a stack of printing paper;
- and
- a printing paper support removably disposed in the cassette and including:
- a flat protecting plate having a length direction and a width direction;
- the first and second ends begin and first and second ends transverse to the length direction disposed within the cassette, and a support surface for receiving a stack of paper,
- a barrier extending along the width direction of the plate and extending substantially perpendicular to the support surface, and
- a grasping surface adjoining the first end of the plate for enabling the paper support to be grasped by a hand without contacting a stack of paper disposed on the paper support.

A printing paper protecting device comprising:
- a paper support including:
- a substantially flat plate having a length direction and a width direction and first and second ends transverse to the length direction, a detecting hole, and an engaging hole at the first end, and
- a first wall extending substantially perpendicular to and form the first end of the plate, a second wall extending from the first wall toward the second end of the plate substantially parallel to the plate, and a third wall extending from the second wall towards and substantially perpendicular to the plate, the first wall having an engaging hole adjoining the engaging hole in the plate.
A printing paper protecting device comprising:
- a substantially flat reinforcing plate having a length direction and a width dimension and a first end transverse to the length direction and having a bendable tab;
- a stack of paper contacting the plate and having a first end surface, the tab extending form the plate over the first end surface of ht stack of paper;
- and
- a packing material enveloping the plate and the stack of paper and including opening mean for removing a portion of the packing material to expose the first end of the plate and the stack of paper.
