Abstract
A pulsed liquid droplet ejecting apparatus array wherein rectangular piezoelectric transducers are arranged abaxially over ink-containing chambers. An edge of each transducer is fixed against a reaction block so that on excitation of the transducers, the transducers extend into the ink chamber ejecting a droplet. The ink chamber is formed in a relatively rigid material to increase the efficiency of utilization of the drive pulse.
