Title: Printing head of wire dot printer
Inventor: TAKAHASHI YUTAKA
IPC: B41J2/295
Filed: 1986-08-20
Abstract: PURPOSE:To increase a printing speed by shortening the restoration stage of a printing pin, by operating a piezoelectric element when the printing pin retracts to a predetermined position and forcibly stopping the printing pin. CONSTITUTION:When a magnet 13 imparts a magnetic field and a pulse current I is allowed to flow to actuator wires 10, 11, in an arrow direction, the actuator wires 10, 11 elastically deform and a printing pin 12 is guided by a guide tube 12 to advance and collides with recording paper 20 to transfer ink to the recording paper 20. When a current I in a reverse direction is allowed to flow at the point of time when transfer is finished, the printing pin 12 retracts quickly. Pulse voltage is applied to a piezoelectric element 17 in timing wherein the printing pin returns to a stationary position. The piezoelectric element 17 collapses the guide tube 16 to brake the printing pin 12. Since the printing pin 12 stops immediately, a restoration stage is shortened and high speed printing can be performed.

Abstract: PURPOSE:To keep the temperature of a vibrator stable by providing a vibrator and a heater such as a positive characteristic thermistor disposed in the vicinity of the vibrator. CONSTITUTION:A vibrator 12 supported by support members 22a, 22b is rigidly fixed to one main face of a support plate 34, and a positive characteristic thermistor 44 is fitted to the center of one main face of the support plate 34.
