Abstract

PURPOSE: To improve pattern distortion by cancelling a beam landing error by a potential supply means for an area other than the electron beam scanning area in the pickup tube having an electron beam generator which scans a fixed area on a photoconductive layer.
CONSTITUTION: In the pickup tube having an electron beam generator which scans a fixed area on a photoconductive layer, transparent electrode 13 is formed to be surrounded with an arc and a chord on plate 12. Further, photoconductive layer 14 is evaporated on electrode 13, and coating electrode 15 is formed on photoconductive layer 14 so that electrode 15 cannot overlap the part scanned by electron beam and contact with transparent electrode 13. Further, electrode 15 is protruded to the circumference side to provide leader line 16 of electrode 15 to the external. Then, potential supply means for photoconductive layer 14 are so constituted that they can be separately supplied to the inside of the electron beam scanning area and the outside of the electron beam scanning area, and a beam landing error is cancelled by the potential supply means for the outside of the scanning area.
