Title: Liquid droplet ejector and image forming apparatus
Inventor: SETO SHINJI
IPC: B41J2/045
Filed: 2007-01-25
Abstract: <P>PROBLEM TO BE SOLVED: To suppress a voltage applied to a piezoelectric element during non driving.  <P>SOLUTION: A switch control circuit 81 turns on a switching element SW43. At this time, terminals at one side (switching element SW43 side) of the piezoelectric elements P5 and P6 are in the same potential. Therefore, even if a drive waveform D<SB>1</SB>and a drive waveform D<SB>2</SB>are generated, a turning voltage generated via the piezoelectric element P6 corresponding to a non-printing nozzle is avoided. Potentials applied to respective terminals at one side of the piezoelectric elements P1, P2, P3 and P4 corresponding to the non-driving nozzles are also of the same value, and therefore a sudden potential change is prevented.  <P>COPYRIGHT: (C)2008,JPO&INPIT
