Abstract: A one-dimensional scanner for use in an image reader in which the pitch of the electrode elements is reduced to increase the image density. An upper electrode array has a plurality of upper electrode elements arranged at a predetermined pitch and spacing in a one-dimensional scanning direction while a lower electrode array similarly has a plurality of lower electrode elements arranged at a predetermined pitch and spacing in the one-dimensional scanning direction in an opposed, spaced and staggered relation with respect to the upper electrode elements wherein each lower electrode element is positioned across two adjacent upper electrode elements thereby defining a picture element region therebetween. A layer of material such a photosensitive material, a layer having an electro-optical effect, or a layer of electric-radiant-energy-converting material is disposed between the upper and lower electrode arrays.

Abstract: A display device particularly adapted for use with a microfilm reader, in which an illuminating light source need be activated only in an initial reading stage. A first transparent electrode, a liquid crystal layer, a semiconductor layer and a second transparent electrode are stacked together in the stated order. A voltage is applied between the first and second transparent electrodes which is switched in a polarity between an initial reading mode and a display mode.

Abstract: A small, light-weight copying machine which is capable of being carried and which includes none of the bulky components ordinarily found in a copying machine. A light receiving element mounted upon a moving element is manually scanned over an original document. The light receiving element produces an image signal which in turn controls a thermal recording head which records upon a heat-sensitive recording sheet. The thermal recording head and light receiving element are both mounted upon a single moving element with the thermal recording head being stationarily mounted thereon and the light receiving element being movable therealong in a longitudinal scanning direction. The heat-sensitive recording sheet is moved in correspondence with lateral movement of the light receiving element.
