Abstract

PURPOSE: To widen a gap between the recording screen and the cathode-ray tube, by making the fluorescent screen operated an electronic scanning with electron beam, with a fluorescent screen constructed in one end of focusing light source (SL), as well as with this screen set to the electronic lens focus face.
CONSTITUTION: Within a cathode-ray tube main unit 11, enclosed into a cylindrical shape, are arranged an electron gun 15 and a SL17, with a phosphor 16 applied to its and face at this electron gun 15 side, respectively, with the setting made for a face of the phosphor 16 to be the face of electronic lens focus. In peripheral face of the cathode-ray tube main unit 11 are arranged a vertical deflecting coil 13 and a horizontal deflecting coil 14, respectively.
