Title:
INK JET TYPE RECORDING DEVICE
Document Type and Number:
WIPO Patent Application WO/1998/047711
Kind Code:
A1
Abstract:
A pressure generating chamber is greatly expanded before ejecting ink droplets to increase the extent of withdrawal of a meniscus line to thereby arbitrarily change distances (d1, d2, d3) from the meniscus to the tip of a nozzle opening at the time of ejection of ink droplets to adjust the weight of each droplet. Accordingly, it is possible to reduce the amount of ink droplets ejected from an ink jet type recording head which has a piezoelectric vibrator as a pressure generating source.
