IPC: B41J2/055
Filed: 1987-12-29
Abstract: PURPOSE:To enable an ink drip to be jetted out even under a low-voltage drive by applying a negative voltage and a positive voltage successively to a piezoelectric element and applying a positive voltage to the other piezoelectric element with a time lag. CONSTITUTION:In the front and rear parts of an ink jet nozzle body 1, ink pressurizing chambers 2a, 2b are respectively formed. In the ink pressurizing chambers 2a, 2b, piezoelectric elements 3, 4 are disposed, respectively. In the piezoelectric elements 3, 4, a negative voltage is applied to the piezoelectric element 4 to reduce the pressure in the ink pressurizing chamber 2b to suck a meniscus once.

The straight line is turned around the center of gravity of the pattern of the input image, the density distribution is cut out on the straight line and it is performed pattern matching with the registered density distribution of a turned pattern. This processing is fast because of one-dimensional pattern matching.  Then, it is possible to perform turning pattern matching which does not need to provide the constraint of a turning angle, also is hard to be influenced by various fluctuation factors, is stable and also has high accuracy.
