APPAREIL ENREGISTREUR A AIGUILLE ENVELOPPEE

摘要

Electrographic recording apparatus utilizing a linear array of conductive styli which is moved in contact with an insulating recording medium along a path through a recording zone and to which are applied signals representative of information to be recorded in the form of latent electrostatic charge patterns. These latent patterns are rendered visible by the application thereto of electroscopic marking particles carried by a fibrous developer which is positioned parallel to and coextensive with the recording zone for rotation about an axis and into contact with the recording medium in the recording zone while the linear array is in motion during its recording cycle.
