Appeal No. 96-2881
Application No. 08/013,646
This is a decision on appeal from the final
rejection of claims 1 and 2, which are all of the claims
pending in the application.
The invention is directed to an ink jet recording
head having at least four rows of nozzle openings. In
particular, the rows are paired so that the interval between
rows within the same pair is smaller than the interval between
rows belonging to different pairs. As illustrated in Figure
1, intervals L1 and L2 are smaller than interval L3. The
nozzle openings of adjacent rows are not in line vertically in
the nozzle plate, but rather are staggered with respect to one
another. Dots are printed via the nozzle openings in a row
sequence of B, D, C, A and B.
Independent claim 1, is reproduced as follows:
1. An ink jet recording head, comprising:
a nozzle plate into which a plurality of nozzle openings are
formed;
means for supplying an ink;
a plurality of pressure producing chambers each
communicating with said plurality of nozzle openings
correspondingly for supplying a pressure to said ink supplied
from said ink supply means to jet said ink from said nozzle
openings;
