Title: (EN) **
Abstract:
(EN) An image pickup tube has markers for discriminating the four corner positions from the effective image pickup zone, which extend corresponding to the four corners of the effective image pickup zone of the electron beam in a transparent electrode patterned on the image pickup tube target, thereby providing a simple and effective adjustment of the scanning zone of the electron beam and the image pickup screen range during the assembly and manufacture of the image pickup tube.
