ABSTRACT:
Apparatus for automatic control of an image storage device. The image storage device, of the type employing a liquid crystal, is utilized in an intermediate processing step during electrostatographic reproduction of the image. An automatic sequence of voltages and illuminations are applied to the image storage device for erasing previously stored images and for preparing the device for storage of an image. The stored image can be applied to a photoreceptor element of an electrostatographic machine for reproduction of the image. The liquid crystal image storage device can be utilized in conjunction with apparatus for displaying signal encoded data. The display of the signal encoded data can be in a format inconvenient for direct application to the photoreceptor, the image storage device serving as a buffer memory for the image. The stored image can be utilized in conjunction with the electrostatographic machine to provide single or multiple copies of the image.
