Title: Driving method for ink-jet type recording head, and ink-jet type recording apparatus
Inventor: YOSHIDA MASAHIKO
IPC: B41J2/055
Filed: 1994-09-26
Abstract: PURPOSE: To repeatedly jet ink drops at a stable speed and by the stable amount irrespective of a frequency through digital processing in a simple circuit, by generating an instruction to expand a pressure generation chamber and suck ink into the chamber one cycle of a basic driving frequency earlier if the basic driving frequency of printing data is a fraction of a specific integer. CONSTITUTION: In the case, e.g. where printing data are output from a printing start position in the order of 1, 0, 1,... (1 is a datum to form a dot and 0 is a datum not requiring to form a dot), if the ink should be discharged with a driving frequency not, larger than 1/2 of a basic driving frequency, a sufficient time is ensured for a meniscus to sit stably at a predetermined position because a piezoelectric vibrator 9 has been electrically charged one cycle earlier than the printing cycle and a pressure generation chamber 3 has been expanded. It, is accordingly prevented that the amount of ink in ink drops becomes short due to the positional irregularity of the meniscus to a nozzle opening.
