Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
139 words
Ink jet recording apparatus of the full line type which comprises: a plurality of ink jet head units each comprising: a multi-array orifice ink jet head for effecting recording at a predetermined position; semiconductor means for driving said ink jet head to project a liquid droplet on demand from each orifice; and multi-layered wiring means for supplying electric signals to said semiconductor means; a plurality of reservoirs for storing ink to be fed to said ink jet heads, each said reservoir being for feeding ink to a respective one of said ink jet head units; and a common supporting member for supporting said ink jet head units and said reservoirs, said ink jet head units and reservoirs each being disposed on said common supporting member so that the relative position between them is maintained during operation of said apparatus.
