Title: Electrostatic latent image reading device for copying machine
Inventor: IKEDA CHIKAO
IPC: G03G15/22
Filed: 1983-10-03
Abstract: PURPOSE:To read out the contents of many charge quantity reading elements in the form of an electric signal without imparing the function of an electrophotographic copying machine by arraying said reading elements equidistantly and in a row and reading out these contents while scanning an electrostatic latent image in accordance with the revolution of a photosensitive drum. CONSTITUTION:The charge quantity reading element 8 is arrayed equidistantly and in a row along a straight line formed at a position close and in parallel to the surface 1a of a photosensitive drum 1. Thus an electrostatic latent image reader 4 is obtained. An electric line of force radiated from an electric charge 9 distributed at the area closest to the element 8 on the surface 1a is made incident to a certain charge quantity reading electrode 8a which has the shortest distance from said electric line of force. The lateral distribution state of the electric charge on the surface 1a is read out through the output of the element 8 in the form of a parallel electric signal in terms of the width of a picture eleement. As the drum 1 revolves at a fixed speed, the charge distribution state on the surface 1a is read out in the form of a serial electric signal through change with lapse of time with the output of the element 8.
