Abstract: A compact thermosensitive printing machine includes a paper supply guide extending obliquely into a housing to a printing roller at its lower end, and a discharge tray on top of the supply guide for receiving the copied paper face-up after it has passed around the printing roller.

Abstract: A copying machine includes an optical sensor of the line scanning type for converting an image into electrical signals, and a thermal recording head controlled in accordance with the image signals. The platen moves with respect to the read unit and the read unit will read in both forward and reverse directions of the platen, and the magnification value can be varied. The total width of energized heating elements and the movement length and speed of the platen may be controlled in accordance with the size of the original. The total number of heating elements energized at any one time is limited, and the machine includes input and output terminals for sending image information externally and for receiving and recording image information other than directly from the read unit.

Abstract: A stencil paper for mimeography is disclosed. The paper is comprised of a porous base which is permeable to mimeographic ink, having thereon a heat-sensitive layer of a material that is solid at ordinary temperatures but which liquifies upon heating. A process for making a stencil is also disclosed, which comprises placing the stencil paper in contact with a receiving medium and selectively heating the stencil paper to liquify portions of the heat-sensitive layer, and allowing the liquified portions of the heat-sensitive layer to transfer to the receiving medium.

Abstract: A device for recording predetermined magnetization patterns on a magnetic recording medium such as for use in a copying machine. The magnetic medium is first magnetized with a uniform magnetization pattern then passed to a thermal printing head upon which a number of heat generating elements are arranged one-dimensionally on a supporting substrate. The heat generating elements are selectively activated to heat the recording magnetic medium to a temperature greater than the Curie temperature thereof so as to change the direction of the magnetization of the magnetic medium in cooperation with a biasing magnetic field.

Abstract: The thermorecording medium is comprised of a support having coated thereon a plurality of heat-sensitive ink materials each having a different melting point. The ink materials can be formed on strip supports wound on rolls which can be utilized by passing the medium close to a finely focused heat source while the inked side of the support is in contact with a recording sheet. The medium may be in the form of an endless belt which can be rotated within a device in such a manner that the medium is continuously reused.

Abstract: In a magnetic latent image forming apparatus the magnetization of the medium is initially set and portions of the medium, selected in accordance with image data, are then heated to temperatures below the Curie temperature of the medium. Before the medium cools, a bias magnetic field is applied to magnetize the heated portions.

Abstract: A stress absorbing roller is disposed in the travel path of the ink donor film in a heat transfer recording device. The roller is pivotable to compensate for alignment errors in the transport system, to thereby eliminate wrinkles in the donor film at the recording station.

Abstract: The retard roll in a paper transport mechanism is rotated by the feed roll to transport manually supplied paper when a photodetector indicates that manually supplied paper is present, the retard roll is substantially stationary and serves its normal purpose of preventing more than one sheet at a time from being transported by the feed roll as it rotates in an opposite direction.

Abstract: A two-sided image recorder employs thermal printing heads and respective ink donor sheets contacting opposite sides of a recording paper as the paper makes a single pass through the recording paper passage.

Abstract: The negative image left on an ink donor sheet after thermal recording is erased by heating the remaining ink at a point downstream of the recording station and either removing the remaining ink or spreading the ink to obliterate the negative image.

Abstract: A thermosensitive copying machine can selectively use either manually or automatically supplied paper, has a pivotable roller and brake mechanism for minimizing wrinkles in the ink donor sheet, supplies the copy paper and donor sheet over paths which differ except at the recording station, and has a separating guide member for peeling the copied paper away from the donor sheet. The donor sheet transport mechanism is enabled only when necessary for a recording operation.

Abstract: A thermal recording medium has two or more kinds of thermo sensitive ink on a base member thereof, and each of the inks has a different melting point and a different color. At least one of the inks also contains an achromatizing agent for concealing a color of at least one of the inks. The thermal transfer recording medium thus constructed is capable of producing multiple colors on a recording sheet by utilizing a device having only one heating head.

Abstract: A multi-color thermal transfer recorder has a thermal recording head, a roll disposed opposite to the thermal recording head, and an ink donor sheet having two or more layers of single-color ink different in color from each other, the length of each ink layer being equal to the length of the outer circumference of the opposing roll.

Abstract: A small, light-weight copying machine which is capable of being carried and which includes none of the bulky components ordinarily found in a copying machine. A light receiving element mounted upon a moving element is manually scanned over an original document. The light receiving element produces an image signal which in turn controls a thermal recording head which records upon a heat-sensitive recording sheet. The thermal recording head and light receiving element are both mounted upon a single moving element with the thermal recording head being stationarily mounted thereon and the light receiving element being movable therealong in a longitudinal scanning direction. The heat-sensitive recording sheet is moved in correspondence with lateral movement of the light receiving element.

Abstract: In a display unit utilizing magnetic bubbles, selective extinction of the magnetic bubbles in a matrix results in a pattern of letters and/or images which are combinations of the magnetic bubbles as picture elements. The present display unit has in-plane anisotropic areas each of which has an easy magnetization axis parallel to the surface of the magnetic bubble material thin film produced by attaching the magnetically soft thin film on the magnetic bubble accommodation spaces in the magnetic bubble material thin film or by ion-implanting into the given spaces of the magnetic bubble material garnet. Therefore, according to this invention, the domain walls of the magnetic bubbles are attracted to said in-plane anisotropic areas and securely held at predetermined picture element positions.

A conductor grating comprising two undulating conductor patterns are provided each cycle of the undulation in both conductor patterns defining a wider pitch and a narrower pitch, each of the wedge-formed patterns being disposed over the corresponding part of one of the two conductor patterns defining the narrower pitch in a manner such that the apex portion and the bottom portion of each wedge shaped pattern extend into the parts forming the wider pitch.
