Appeal No. 1998-2467 Page 3
Application No. 08/353,682
BACKGROUND
The appellants’ invention relates to a detachable battery
pack for electro-optical scanners. An understanding of the
invention can be derived from a reading of exemplary claim 41,
which is reproduced as follows:
41. In a system for electro-optically reading indicia
having parts of different light reflectivity, a scanning head
comprising:
a) a hand-held, generally gun-shaped housing having a
hollow handle sized to fit in a hand of a user, said handle
extending away from the housing along a handle axis to a
handle end and having a predetermined cross-sectional
dimension, said housing being movable relative to an indicium
within a range of working distances;
b) a DC voltage-powered, solid-state light source mounted
in the housing, for directing a light beam away from the
housing toward the indicium for reflection therefrom;
c) a sensor for detecting light of variable intensity
reflected off the indicium over a field of view, and for
generating a signal indicative of the indicium;
d) means for automatically scanning at least one of said
light beam and said field of view;
e) decode control means for decoding the signal, and for
controlling the automatic scanning, said decode control means
being mounted on a printed circuit board insertable and
accessible through the handle end for mounting in the handle;
f) an electrical connector;
g) one of the printed circuit board and the electrical
connector having electrically conducting pins extending along
