Patent

CA 2048194

An apparatus for reading information from an information medium and/or inputting information to the information medium through a probe electrode comprises a voltage application circuit for applying voltage between the probe electrode and the information medium, information reading from the information medium and/or information inputting to the information medium being performed by the voltage application by the voltage application circuit, and an electric removing device to perform the electric removing process for the information medium to which voltage is applied by the voltage application while maintaining the information in the information medium; making it possible to perform a highly precise information reading and/or inputting at all times without producing any adverse effects on the information medium due to the charge deposition resulting from the voltage application.

ppareillage servant à lire l'information sur un support d'information et/ou à y entrer l'information au moyen d'une électrode sonde, comprenant un circuit de tension servant à appliquer une tension entre l'électrode sonde et le support d'information, la lecture de l'information sur un support d'information et/ou à l'entrée de l'information sur le support étant effectuées par l'application d'une tension par le circuit de tension, et dispositif de suppression de l'électricité servant à supprimer l'électricité sur le support d'information auquel la tension est appliquée atout en conservant l'information sur le support d'information; permettant ainsi de lire et/ou d'entrer de manière très précise l'information en tout temps sans entraîner d'effets défavorables sur le support d'information à cause d'une charge électrique par suite de l'application de la tension.
