    摘要： In a driving method of an optical switch element for controlling a quantity of transmission light between opposed electrodes by interposing a transparent, high dielectric material (4) between the opposed electrodes (6a, 6b) and applying a positive or negative voltage between the opposed electrodes, (by changing over a switch 13 from a terminal a to terminal b or terminal c) the improvement wherein a period in which the opposed electrodes are substantially short-circuited is disposed in order to make it possible to either reduce or eliminate stored charge. This method can be applied in a printer using the optical switch element.

    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:
    (where to, t 1 , t 2 and t 3 are times) if the voltage applied to a said ferroelectric liquid crystal during a printing operation is V 1 , the period during which said voltage V, is applied is T, (= t 1 - to), the period during which a photoconductive surface is moving is T 2 (= t 3 - t 2 ), and the voltage applied during said period T 2 to said ferroelectric liquid crystal is V 2 .
    The invention refers also to the corresponding printer.
