Driving method of a liquid crystal switch for a printer, and printer therefor.

摘要

The invention refers to the driving method of a liquid-crystal switching element of a printer in which a ferroelectric liquid crystal is sandwiched between a pair of plates provided with electrodes on adjacent surfaces thereof, which is characterized in that the following equation is substantially satisfied: <CHEM> (where t0, t1, t2 and t3 are times) if the voltage applied to a said ferroelectric liquid crystal during a printing operation is V1, the period during which said voltage V1 is applied is T1 (= t1 - t0), the period during which a photoconductive surface is moving is T2 (= t3 - t2), and the voltage applied during said period T2 to said ferroelectric liquid crystal is V2. The invention refers also to the corresponding printer.
