Abstract: A thermal printer utilizes a donor web bearing a transfer ink to create enhanced printed images on a strip of sheet material with half-tones, color and other attractive features. The donor web is mounted on supply and take-up spools within a cassette that is removable from the printer in order to change the color or other printing characteristics of the web for various printing operations. A drag brake mounted in the printer connects with the supply spool through a disengageable coupling to maintain tension on the donor web during printing and to allow the web and cassette to be removed from the printer. A feed detection sensor in the form of an optical encoder is also contained within the printer and coupled to the supply spool through the same disengageable coupling utilized by the drag brake to detect feed faults.

Abstract: A thermal transfer recording device including a thermal line head having heat generating elements thereon, a record paper in form of a roll of paper, a platen roller disposed in opposition to the thermal band, an ink jet sheet interposed between the platen roller and the thermal head and extending on opposite sides with respect to the platen roller, and at least a first record paper transport device disposed upstream in the transporting direction of the record paper with respect to the platen roller for at least feeding the record paper from the roll of paper toward the platen roller. At least a first wrapping member disposed on the first record paper transport device side with respect to the platen roller and arranged for pressing the ink sheet toward the platen roller when the thermal head is in a non-printing position floating above the platen roller so that a leading edge of the record paper transported by the first record transport device is guided by the ink sheet and by the wrapping member along the platen roller with sufficient tension to enable the leading edge of the record paper be fed without wrinkling of the record paper through the path therefor extending from the first record transport device.

Abstract: In an electrophotographic printer using a continuous-form sheet on which a visible image, having been formed on a predetermined photoconductive material, is to be transferred by means of a transferring charger unit movable between an operating position, in which the transferring charger unit presses the continuous-form sheet being fed in a predetermined direction on the predetermined photoconductive material, and a retracting position in which the transferring charger unit is retracted from the operating position, for separating the continuous-form sheet from the predetermined photoconductive material when the transferring charger unit is located at the retracting position: the printer including a sheet separating mechanism comprising a rock member arranged to be supported by a shaft member located above the continuous-form sheet and mounted on the continuous-form sheet. Thus, the continuous-form sheet is downwardly tensioned by weight of the rock member and accurately separated from the photoconductive.

Abstract: A thermal printer comprises a pair of fixed frames for rotatably supporting a platen which is rotated by a motor and a head unit rotatably supported by the fixed frames through a pair of movable frames and for supporting a thermal head. A pair of pinch rollers are rotatably mounted on the fixed frames, which are selectively brought to a first operating state to feed a paper sheet to the region between the platen and the thermal head, and a second operating state to feed no paper sheet. The thermal head is selectively moved between a first position, in which it is pressed against the platen, and a second position in which it is disengaged from the platen. The thermal head is moved to the first position, at the same time the pinch rollers and moved to the second operating state, while the thermal head is moved to the second position, at the same time the pinch rollers are moved to the first operating state.

Abstract: A printer of a wire-dot impact type is provided forwardly of the housing an inlet opening for introducing a printing paper to the inside and has an outlet opening provided at a rear side of the housing for discharging the printing paper to the outside. The printing paper is transported by cooperation of a tractor arranged near the outlet opening and a feed roller arranged near the inlet opening, to thereby run inside the housing in substantially a straight path of travel from the inlet opening to the outlet opening, during which the printing paper is printed by means of a platen and a printing head, both provided between the feed roller and the tractor. A pair of guide members are provided between the feed roller and the printing unit and between the printing unit and the tractor, respectively, to thereby feed the printing paper along the straight path of travel.

Abstract: A precision tape feed and guide mechanism is disclosed. The guide includes a base plate (308) and a hold-down plate (314) with fingers (316, 318). A spring (345) biases the fingers against the tape (301) during printing. Actuation lever (330) which is pivoted on point (332) causes plate (314) to lift out of contact with the tape and permit its easy removal. Feeding or incrementation of the tape is accomplished by an incompressible roller (350) removably biased against roller (352) which includes a recessed portion (356) having an incompressible O-ring (354) residing therein and biased against roller (350) with a tape (301) therebetween.
