Title: Driving method of ink jet device
Inventor: CHIYOU KIMEI
IPC: B41J2/055
Filed: 1993-07-02
Abstract: PURPOSE:To prevent the generation of accidental dropping or air bubbles while keeping high speed printing by shifting the timings of a drive pulse applying pressure to ink chambers close to each other among the ink chambers of the same group. CONSTITUTION:The pressures in respective ink chambers are respectively reversed according to a pressure wave propagation thereof and, for example, positive pressure is generated in an ink chamber 4a. A pulse is completed in matching relation to this timing and side walls 6a, 6b return to a state before deformation and high pressure is generated in the ink chamber 4a and an ink droplet is injected from the nozzle communicating with the ink chamber 4a. At the same time, the voltage pulse applied to an ink chamber 4c rises and side walls 6c, 6d are deformed. When this deformation is observed from the adjacent ink chamber 4b, the side walls on both sides are moved by the same quantity in the same direction and no volumetric change is generated in the ink chamber 4b.

When claws 8 of the pusher 7 are fitted into a groove on the outer peripheral surface of the cylinder 6, the pipes 4a, 4b can be fixed. When the claws 8 come out of the groove of the cylinder 6, the pipes 4a, 4b are moved horizontally to the left by the springs 5 to push up the shafts 2.  Thus, the spool having variations in its inside diameter, can be clamped without eccentricity.
