Title: Liquid jet apparatus and ink-jet printer
Inventor: YANO KENTARO

Filed: 1992-01-18
Granted: 1997-01-04
Abstract: Delay of refilling to be conducted immediately after the first discharge in the continuous discharge can be restricted. Adequate air bubbles (9,10) which do not adversely affect discharge can be formed by means of the air bubble forming unit, such as a sub-heater for heating the ink reservoir portion, such as a common liquid chamber (15). The formed air bubbles (9,10) function as the buffers and thereby absorb the discharge energy (pressure waves) directed toward the common liquid chamber (15) during discharge to restrict flow of the ink in the direction opposite to the discharge port. That is, refilling after discharge can be quickly performed. <IMAGE>
