<p><P>PROBLEM TO BE SOLVED: To prevent a plurality of switches from entering an ON state simultaneously when switching a drive signal. <P>SOLUTION: A liquid ejection apparatus includes: a piezo element 417 that can perform operation of ejecting ink; a drive signal generation section 70 that generates a first drive signal COM_A and a second drive signal COM_B; a first switch 86A that controls application of the first drive signal COM_A to the piezo element 417; a second switch 86B that controls application of the second drive signal COM_B to the piezo element 417; and a controller (prevention circuit 85) setting both of the first switch 86A and the second switch 86B in an OFF-state when switching the drive signal applied to the piezo element 417 from the first drive signal COM_A to the second drive signal COM_B. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
