    Abstract: Methods of forming a nozzle plate include forming a first reverse imageable positive photoresist layer on the substrate and protecting an area thereof adjacent an ink ejection element from ultraviolet energy while exposing other than the protected area to such energy. Thereafter, the non-protected area is rendered insoluble by heating. Thereafter, the protected area is exposed to ultraviolet energy to weaken its structure for later removal. A second reverse imageable positive resist layer gets formed on the first layer and exposed to ultraviolet energy in a region directly above the ink ejection element. In a single step, both the protected area of the first layer and the non-protected region of the second layer are removed to form an ink flow feature, a bubble chamber or an orifice of the nozzle plate. The remainders of the first and second layers become blanket exposed to ultraviolet energy and cured in place.

The case is formed with an opposing pair of guides and the inoperative position of the guides is determined offset from the operative position where two supporting members are mechanically engaged to the guides in the housing of an image building apparatus. When the support members are practically engaged to the guides, the inner wall of each of the guides is brought in uniform close contact with the outer surface of each of the support members under the effect of elastic force generated by engagement of the latter to the guides. Thus, any uneven area on the guides which is developed at a time of molding can be automatically eliminated by fitting the transfer material holding cassette to the holding of the apparatus.

  • Patent number: 4661826
    Abstract: In picture image forming apparatus employing a copying paper and a transfer printing ribbon with both ends connected to take up cores, when the leading end of the copying paper is located close to a transfer printing unit, the tension of the ink ribbon is increased for preventing clogging of the paper and misalignment of printed picture images. Further, the tensions applied to the both ends of the ribbon are controlled to apply a braking force to the ribbon and then stop the same for the purpose of preventing over running of the ribbon.

  • Patent number: 4661824
    Abstract: A thermal printer which includes a selectively energized thermal head that is located opposite to a platen and is capable of thermally transferring ink from an ink supply onto paper fed between the ink supply and the platen. A heater element is selectively operated, in response to a detector sensitive to the grade of paper, to heat the paper after it has had ink transferred to its surface and is fed out from between the head and the platen.

  • 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: 4642659
    Abstract: The improved image building apparatus is constructed such that recording medium, that is, recording paper, is normally introduced into the image building section with a thermal head or the like component incorporated therein while it is stretched under the effect of a certain intensity of braking force which is exerted on the recording paper from the rear side as seen in the direction of transportation thereof. This causes an occurrence of such a malfunction as skewing, loosening or the like of the recording paper to be inhibited at least in the image building section. Thus, image building can be achieved without incorrect registering, deformation or the like recognized with the printing paper on which image transference has been carried out.

  • Patent number: 4642656
    Abstract: A thermal printer automatically varies torque of a slip clutch provided between a motor and an ink film takeup roller with movements of a thermal head such that the torque transmitted to the takeup roller is smaller when the thermal head is in a transfer position than when the thermal head is in a non-transfer position. This assures that the takeup roller is driven properly by increasing the torque transmitted to the takeup roller when the thermal head is in the non-transfer position and an ink film is taken up in a large amount. When the thermal head is in the transfer position and the ink film is taken up in a small amount, the torque transmitted to the takeup roller is reduced to avoid a great tension acting on the ink film.

  • Patent number: 4641151
    Abstract: A device associated with a thermal transfer recording apparatus for boosting a pressing force of a thermal head against a platen roller. The thermal head is mounted on one end portion of an elongate support plate which is movable in a seesaw motion about a fulcrum. Output torque of a rotary solenoid device is transmitted to the support plate by a rotary shaft which is connected to the solenoid device, so that the support plate is moved about the fulcrum to press the head against the platen. During recording, an extra drive force is derived from a tension of an ink sheet and imparted via the rotary shaft to the support plate to move the support plate, serving to further intensify the pressing force of the head against the platen.

    Abstract: A thermal printer having a reciprocable carriage on which a thermal head is carried. The printer further includes a rotatable gear for winding print tape, a toothed rack that can move toward and away from the winding gear, and a driving plate for reciprocating the rack in association with the rotation of the carriage. When characters are to be printed, the carriage is rotated to the platen, and the teeth of the rack are brought into mesh with the winding gear. When no characters are printed, the carriage is angularly moved away from the platen, and the teeth of the rack are disengaged from the winding gear.

  • Patent number: 4641148
    Abstract: A wear-resistant ribbon guide surface (11 or 25a, 25b) is added to a thermal printhead (1) to lower the ribbon exit angle after printing or to shift the ribbon exit position away from the printing. The angle past that surface remains large enough for visibility of prior printing. The modification of exit conditions makes the printing darker and significantly improves printhead life.

When the printing position is set above as against the center of width of the ink ribbon, the center of the thermal head is set above width (P) of the flat portion being formed on the platen roller of the contact portion of the thermal head. When the printing position is set below as against the center of width of the ink ribbon, the center of the thermal head is set below width of the flat portion being formed on the platen roller of the contact portion of the thermal head.

    Abstract: A closed loop thermal transfer recording system and color transfer ribbon having a plurality of different color ink stripes thereon are provided for recording a color tonal image on a recording sheet. Precise control over the size of dots formed by ink transfer is achieved by monitoring the density of a thermally sensitive indicator layer on the back side of the ribbon which provides, for each different ink color, indicator marks that are proportional to recorded pixel density, and feeding this information back to a control system which compares monitored density with desired density and regulates heat input to the ribbon accordingly.
