OPTICAL SWITCH AND INK-JET PRINTER

摘要

The printing speed and resolution of an ink-jet printer are improved by making the wiring pattern finer and increasing the number of individual driving circuits which are required for obtaining a line head, while avoiding high-voltage operation and the increase in cost of the printer. The ink-jet printer is constituted in such a way that ink jetting mechanisms respectively using piezoelectric bodies (3) are arranged in parallel and one electrode of the bodies (3) is independently connected to photoconductors, and then, the other electrodes of the bodies (3) are connected to the other electrodes of adjacent bodies (3). The ink jetting mechanisms emit ink by deforming one of the piezoelectric bodies (3) by selectively irradiating the corresponding photoconductor (5) with light (12) from an optical scanning device. The printer uses an optical switch.
