INJECTION DEVICE OF PRINTER USING CRT

摘要

The scanner includes an electron gun (EG) depositing the inner sides of glass plates (20,21) for radiating the laser beam, a horizontal deflection controller (HD), metal wires (261-26n+1) arrayed with certain intervals for forming a negative charged dormant image on the drum charged by positive electrons emitted by the electron gun, and a sealing glasses (22,23) for sealing the glass plastes (20,21) and the metal wires (261-26n+1).
