  • Patent number: 5162838
    Abstract: A facsimile apparatus has a transparent plate on which a document may be located. The document is then scanned by a scanner which includes electronic solid state light generation means e.g. LEDs which illuminate the document, with the light reflected from the document being detected by a detector. An electronic signal corresponding to an image of the document may then be transmitted to a remote location. Alternately, the facsimile apparatus may be used to copy the document. Cut paper sheets are withdrawn from storage and an image printed thereon by a heat transfer system in which a film of ink is selectively heated. Paper on which an image has been printed is then received on the upper surface of the storage. The facsimile apparatus may also have a document transporter for moving a document past the scanner with the scanner fixed.

  • Patent number: 5157505
    Abstract: In a technique in which a thermosensitive recording paper and a recording head are arranged in contact with each other and a voltage is applied to the recording head in accordance with an image to be recorded while the recording paper being transferred by a motor, striped lines, so-called blanks, where no image is recorded, appear because of a delay on starting the motor. The present invention solves this problem by delaying the timing of the image recording by the amount of the delay in starting the motor.

  • Patent number: 5144343
    Abstract: An image recording apparatus including a recording electrode having electrode needles aligned in columns, a driving circuit for individually applying an image recording voltage to the electrode needles of the recording electrode, a recording medium composed of a conductive layer and a surface insulating layer, and a voltage circuit for applying a predetermined voltage between the recording medium and the electrode needles, whereby fog on the recorded image can be avoided.
