Abstract
A contact type amorphous linear image sensor is disclosed with planar comb-shaped electrodes. Photoelectric converting elements are linearly aligned on a stripe-shaped amorphous silicon layer formed on an insulative substrate. These elements serve as photoconductive cells and are divided into M cell groups. Each cell unit includes N comb-shaped individual cell electrodes and a multi-tooth comb-shaped common electrode, which are spacially meshed or overlapped with each other. A drive voltage detector is connected through a matrix circuit configuration to the cell electrodes, which are arranged such that two-side-ended cell electrodes surround in each cell unit the both side-ended teeth of the corresponding common electrode, so that the adjacent side-ended teeth of the neighboring common electrodes are electrically shielded by the side-ended teeth of the cell electrodes. A signal detecting pre-amplifier is connected to the common electrodes through analog switches and a load resistor.
