Abstract

Information reading and/or inputting apparatus has a probe, an electrodes, a detector, a position controller and a probe and portion forming device.
By positioning the probe close to an information medium, information reading/inputting is effected in the apparatus. A voltage is applied to the probe through the electrode. Information on distance between the electrode and the probe is detected by the detector and whereby the relative position of the probe to the electrode is controlled by the position controller. The end portion of the probe is reformed in such a manner that a voltage is applied to the end portion of the probe through the electrode under controlling the relative position of the probe to the electrode by the position controller. A high reliable performance for the apparatus can always be attained by the probe reforming mechanism.
