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. A scanning device is provided which selects respective pairs of the upper and lower electrode elements which overlap each other sequentially in the one-dimensional scanning direction. At least one of the upper and lower electrodes is light transmissible.
