    Abstract: An image forming apparatus comprising an exposure light source, a printer head which comprises a group of micro-shutters each controlling the transmission or interruption of light from the exposure light source, and an image bearing so disposed to be irradiated with light signals transmitted through the printer head. The group of micro-shutters are arranged in a matrix comprising a plurality of rows and a plurality of columns. The group of micro-shutters are formed by a substrate having thereon a plurality of segment electrodes each forming a shutter and connected to a drain of a thin film transistor, another substrate having thereon a common electrode, and a liquid crystal interposed between the substrates. The image forming apparatus further comprises means for applying a scanning signal to the gate of the thin film transistor and applying an electric signal corresponding to image information in synchronism with the scanning signal.

    Abstract: There is provided an image forming apparatus comprising: a readout sensor for reading out an original which is illuminated by a light source; a converter for converting image information which is read out by the readout sensor to a binary signal; printing heads for recording the image information on a recording paper in response to an output of the converter; and a driver for relatively carrying the readout sensor with regard to the original or recording paper. A plurality of sets of those readout sensors, converters and printing heads are arranged in a line on the same substrate. An amount of scan movement of this apparatus is detected and the driving operations of the light source and the image readout sensor or printing head are synchronized for every unit moving amount, so that occurrence of variation in concentration of the reproduced image and a risk of fire can be prevented. Also, a remarkable energy saving effect can be obtained in case of driving the apparatus by a battery.
