    摘要: A heat-sensitive recording head having heat generating elements arranged on an insulating substrate and a system for preheating said substrate and controlling the heat generated during the recording operation. In one embodiment the substrate is placed in contact with a larger heat sink which is heated by a carbon-type internal resistor, a printed circuit contacting resistor, or a conventional heater. A thermal sensor detects the temperature of the heat sink and is fed to controls for controlling the overall application of heat. In another embodiment the substrate is placed in contact with a Peltier effect device which controls heat generation and absorption.

    摘要: 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.

    摘要: A step motor driving circuit having A-phase and B-phase exciting windings which are independently supplied with exciting current in a sequence of four states per step of the step motor. The driving circuit is capable of applying a large or a small current to each phase winding and the currents are applied in a sequence to result in a trapezoidal shaped exciting current. During a first state only one phase is excited and it is excited with the large current. During the second state the one phase is excited with the large current and the other phase with the small current. During the third state both phases are excited with large currents. During the fourth state the one phase is excited with the small current and the other phase with the large current.

    摘要: 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. Either the platen or read unit are movable and the read unit will read in both forward and reverse directions of movement, and the magnification value can also be varied. The total width of energized heating elements and the movement length of the read unit or 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. A cutter is provided for cutting the recording paper web immediately prior to discharge.

    摘要: A method of driving a heat-sensitive recording head with a very small number of components. In the recording head, leads are arranged on an insulated substrate extending on both sides of the substrate in parallel with one another with heat generating elements disposed between adjacent leads. A microcomputer divides data inputted thereto in a time division manner into data blocks each having a predetermined amount of data. The data in each data block is rearranged by skipping data every predetermined number of data. The data thus rearranged is applied in a parallel mode to a plurality of shift registers and from the shift registers coupled to leads on one side of the recording head successively.
