Appeal No. 2001-1739
Application 08/892,903
The invention relates generally to microscopes. See page 1
of Appellant’s specification. Appellant’s figure 1 shows an
isometric view of the present invention of a microscope having a
camera mounted thereon. See page 5 of Appellant’s specification.
Appellant’s figure 3 shows a preferred focus adjusting apparatus
for the upper rim of cylindrical sleeve 8. Cylindrical sleeve 8
has a slope 50, which works in combination with a rivet or nub 51
on the optical tube 9 to enable fine focus adjustment by rotating
the optical tube 9 to cause nub 51 to travel along the slope 50
of the cylindrical sleeve 8. See pages 6 and 7 of Appellant’s
specification. The sleeve 8 does not completely encircle the
tube 9, thus providing a channel 52, through which the nub 51 can
pass to enable gross focus adjustment. See page 7 of Appellant’s
specification.
Independent claim 23, the only independent claim before us,
is reproduced as follows:
23. A microscope comprising:
an optical tube for magnifying an image of a specimen to be
viewed, said optical tube having an optical tube optical axis
along which said optical tube is selectively moveable to alter
said image; and
an optical tube sleeve in which said optical tube is
rotatably and slideably retained;
