Abstract: The present invention relates to a thermomagnetic recording apparatus in which a chemical compound material the Curie point of which varies in response to a ratio of chemical combination in chemical compound constituent is utilized as a magnetic material for its magnetic recording medium, and the Curie temperature is set higher than the ambient temperature by a prescribed value on the ratio of chemical combination determined, thereby resulting in printing at a relatively low temperature and precision of printing in a prescribed degree.

Abstract: A thin film magnetic recording head and process for fabricating it is disclosed. The magnetic recording head has a core with a gap the same length as the width of an original document to be produced and is positioned in contact with a moving magnetic recording medium and perpendicular to the direction of movement thereof. A high magnetic permeable body is disposed in the gap of the head core and is in contact with the magnetic recording medium. A heat generation body of the same length as the high magnetic permeable body is positioned in contact therewith. Means for selectively heating segments of the heat generation body corresponding to the width of a picture element is provided.

Abstract: A scanning type readout device having a photoelectric conducting layer and electrode segments arranged one-dimensionally on one surface of the photoelectric conducting layer. The electrode segments are electrically insulated from each other and each has a size equal to one image element and opposite electrodes are arranged on the other side surface of the photoelectric conducting layer so that each of the opposite electrodes is in opposition to a plurality of the electrode segments. First semiconductor switches are connected respectively to the opposite electrodes and second semiconductor switches connected respectively to some of said electrode segments.
