摘要： A device is used for changing into electrical signals indicia applied to an information carrier in the shape of nonlevel markings, such as holes, notches and the like. The device is particularly characterized by a piezoelectric converter connected with feeling means which are resiliently pressed against the inscribed lengths of the information carrier, as well as a transporting device for shifting the information carrier relatively to the feeling means in the direction of the inscribed lengths.
