ABSTRACT:
The position detector comprises a semiconductor layer of i type amorphous silicon layer and a P type amorphous silicon layer is formed on one surface thereof and an N type amorphous layer is formed on the opposite surface. A transparent resistance layer is formed on one surface of the semiconductor layer. Collector electrodes are provided at the sides of the resistance layer for deriving out a position signal.
