Appeal No. 96-1918
Application 08/196,931
Clark discloses a housing 12, which detects
translational movement in an x direction and a y direction
like a mouse. A tower 62 is mounted on the housing 12 and
has a finger operated conveyor belt 64 with finger holes 74
for controlling the translation motion of an object on the
display of a computer with respect to a third translational
axis. Although it is difficult to judge scale, there are
five finger holes 74 illustrated in the conveyor belt 64,
which suggests that the tower 62 is "at least three fingers
of a human hand" in height. Since the tower 62 is upright,
the fingers may be curled around the tower when the "hand is
positioned perpendicularly to said base unit." The tower 62
could be used as a handle with three fingers wrapped around
it with the hand perpendicular to the base. Use limitations
do not impart structural features. Therefore, claim 1 does
not define structurally over Clark.
Nishiwaki, figure 6, discloses a grip case 35 attached
to a base plate 34 which contains a pickup coil 31 to sense
the coordinate position. The grip case 35 is described as
having a suitable width from 10 mm to 25 mm and a height
greater than its width to provide sufficient contact area
