Title: Driving method for printing head employing piezoelectric element
Inventor: HOSOKAWA KOJI
IPC: B41J2/295
Filed: 1989-03-16
Abstract: PURPOSE:To stabilize the action of a wire being a printing member and to improve printing quality by continuously charging at the beginning of charging a piezoelectric element and discharging the piezoelectric element right before the printing member reaches the most advanced return position after it impacts via an expanding mechanism. CONSTITUTION:The contraction and expansion of a piezoelectric element 2 due to charging and discharging is transmitted to a wire 5 being a printing member via an expanding mechanism composed of a flat spring 3 which is supported by a base 1 in a cantilever fashion and an armature 4 expandingly transmitting the action of the flat spring 3. The piezoelectric element is continuously charged at a start (a), and is discharged right before the wire 5 reaches the most advanced return position (c) after it impacts to develop vibration, as mark (c') shows. Consequently, the kinetic energy of the wire 5 itself almost disappears before the piezoelectric element 2 is completely discharged after it begins to be discharged, and the wire 5 speedily attenuates around its initial position (a).
