  • Patent number: 5070414
    Abstract: To read a document accurately and produce an image signal faithfully representing the document, an image reading method and apparatus adopts various means, of "latching an average light-shielded signal in a digital form", "using an average light-shielded signal resulting from averaging output signals of a plurality of light-shielded pixels as a black reference signal", "replacing that part of an image signal in which an average light-shielded signal is larger than an effective pixel signal in level with a signal of a zero level", "driving CCD sensors at such timing as to allow effective pixel signals output from the CCD sensors to be continuous in time" and "setting DC offset voltages of signals output from CCD sensors to a predetermined clamp potential.

  • Patent number: 4717270
    Abstract: A paper circulating assembly is provided for use in a field sequential printing apparatus such as a facsimile. The facsimile includes an ink ribbon having multiple color ink segments. A piece of paper is conveyed ultimately into a printing paper path and to the ribbon and printing platen for printing. The printing platen conveys the leading edge of the printed paper to a gripping arm of the paper circulating assembly. After a predetermined time period, the leading edge of the paper rests in the gap created between the gripping arm and the gripping platen, and the gripping arm closes against the gripping platen. Thereafter, the secured leading edge is conveyed to a recirculating paper path which flows into the printing paper path, and stays in this position until the trailing edge of the printing paper is just about to enter the printing paper path. During this time, the portion of the paper which lies between the gripping arm and the printing platen gathers in a loop in a paper loop area.

  • Patent number: 4675698
    Abstract: In a thermal transfer recording method of the type using a strip of repeatedly usable ink ribbon wound about an ink ribbon feeding roll, recording is effected by means of a line scanning type thermal head while recording paper and ink ribbon are transported forwardly in the superimposed state. At every time when recording has been achieved both the recording paper and the ink ribbon are released from the clamped state which is caused by means of a combination of platen roller and thermal head and thereafter the ink ribbon is transported backwardly by a distance shorter than the length of a single page. A short part of the ink ribbon transported backwardly on which recording has been effected is put in use again for next recording operation.

  • Patent number: 4660053
    Abstract: In a thermal transfer recording method for use in a recording apparatus using a roll of recording paper of an ordinary paper material wound about a core and a strip of ink ribbon would about an ink ribbon feeding roll, recording is effected by means of a thermal head while both the recording paper and the ink ribbon are transported forwardly in the superimposed state. During transportation of the recording paper and the ink ribbon after the recording, they are parted away one from the other and only the recording paper is transported to an automatic cutter by means of which a part of the recording paper on which recording has been effected is cut off. After completion of cutting operation an unused parts of the recording paper and the ink ribbon are transported backwardly to the position where the leading end of the thus returned recording paper is located in the proximity of the thermal head.

  • Patent number: 4639739
    Abstract: In a thermal transfer recording method for use in a recording apparatus using a roll of recording paper of an ordinary paper material wound about a core and an ink ribbon wound about an ink ribbon feeding roll, the recording paper and the ink ribbon are transported forwardly while they are superimposed one above the other and the recording is effected by means of a thermal head during their transportation. While the recording paper and the ink ribbon are released from the clamped state by means of the platen roller and the thermal head, only the recording paper is transported to a cutter where a recorded part of the recording paper is cut off. An unused part of the recording paper is then transported to until its leading end reaches the thermal head, where the recording paper and the ink ribbon are superimposed one above the other again.

  • Patent number: 4635357
    Abstract: An electrostatic recording head has a plurality of electrode wires arranged parallel to each other at a predetermined pitch to form recording electrodes at one ends thereof, control electrodes arranged along these recording electrodes, and a recording electrode retainer for integrally fixing these electrodes with a resin. The other ends of these electrode wires are integrally fixed by an electrode wire terminal end retainer of a resin. The electrode wires are electrically connected to a part of the conductive pattern formed on a printed circuit board interposed between both retainers, and are grouped thereby to form a plurality of recording electrode set conductors. These conductors and lead wires connected to the control electrodes are connected to connector terminals. A recording voltage is applied to the connector terminals.
