Paper Roll Door for Printer in a Handheld Computer

      A generally cylindrically shaped door 10, forming a housing for
a printer paper roll in a small handheld computer, opens and closes
with the use of groove and pin arrangements to facilitate easy
removal and insertion of the paper roll.

      As seen in Fig. 1, which is an isometric view, the paper roll
door 10 includes a cylindrically shaped top 12, which is preferably
made of transparent material, a first circular side 14 attached to
one end of the top 12 and a second circular side 16 attached to the
opposite end of the top 12.  The door 10 is designed to cover a slot
18 in a chassis 20 of a printer adapted to receive a paper roll (not
shown).  The length of the slot 18 is defined by a first endwall 22
located at one end of the slot 18 and by a second endwall 24 located
at the opposite end of the slot 18.  Each of the endwalls 22 and 24
includes a first groove 26 and a second groove 28, as seen more
clearly in Fig. 2, which is a view of the endwall 22 taken along the
longitudinal axis of the slot 18, with the second endwall 24 being a
mirror image of the first endwall 22.

      The first groove 26 in the endwall 22 begins in the lower
portion of the endwall 22, near the edge thereof, and extends
vertically toward the upper portion of the endwall 22 for a major
portion of its length and then curves left into the edge of the
endwall 22.  The second groove 28 in the endwall 22 also begins in
the lower portion of the endwall 22, near the edge thereof, and
extends vertically toward the upper portion of the endwall 22 for a
major portion of its length and then curves left to a point short of
