  • Patent number: 6454476
    Abstract: An apparatus and method for picking and feeding a single sheet from a stack. A pick roller and a retard roller are held together in a pick assembly, and positioned so that the pick roller is in contact with the top surface of the top sheet and adjacent a leading edge of the top sheet. The pick roller is driven to pick a sheet from the stack, pulling the sheet into the nip between the pick roller and the retard roller. The retard roller applies a retard force to the retard roller tending to resist the rotation of the retard roller as print media is driven into the nip during a pick operation. The retard force is less than a feed force applied to the top sheet by the pick roller as the top sheet is passed into the nip, the retard force being greater than a sheet-to-sheet frictional drag force between the top sheet and an adjacent sheet, thereby separating an adjacent sheet from the top sheet to prevent multiple sheet picks.

    Abstract: Apparatus for the selectably alternative feeding of single sheets and of endless webs of paper in a printer includes a guide roll (7), and first and second groups (8, 9) of friction rollers concurrently movable between first and second positions to define respective single sheet and endless web feeding modes of operation. In their first positions, the first friction rollers (8) contact the guide roll (7) to define a first single sheet feed channel (4) and the second friction rollers (9) contact the guide roll (7) to define a second single sheet feed channel (5). When shifted to their second positions, the first friction rollers (8) are displaced from their first position contact with the guide roll (7) to substantially eliminate the first single sheet feed channel (4), and the second friction roller (9) are lowered to form with the guide roll (7) an endless web feed channel (6).

  • Patent number: 5138341
    Abstract: A plotter wherein, while a sheet is being moved on a recording surface, figures, characters etc. are automatically depicted on the surface of the sheet, or the contours of figures, characters etc. are automatically cut in the surface of the sheet. In the plotter, both the side edges of the sheet are respectively held between drive rollers and corresponding pinch rollers mounted at both the sideward parts of the recording surface in opposition to each other, and the drive rollers at both the sideward parts of the recording surface are rotated synchronously to each other, whereby the sheet is moved in the rotating direction of the drive rollers on the recording surface. Each of the drive rollers is formed at its peripheral surface with milling or ruggedness for preventing the sheet from slipping.

  • Patent number: 5129749
    Abstract: The line printer is provided with a pinch roller for feeding a spring medium sheet by capstan drive. The pinch roller is pressed by an integrated pressing mechanism comprised of a spring holder, a pressing spring member disposed in the holder and a bearing piece connected to the spring member in contact with the pinch roller. A pressing lever is shiftable between a pressing position effective to apply pressing force to the integrated mechanism and a release position effective to release the integrated pressing mechanism. The released pressing mechanism or unit is moved away from the pinch roller to free the same to leave a significant gap between the pinch roller and a capstan roller, thereby facilitating removal of a jammed print medium sheet. Further, the integrated pressing mechanism facilitates maintenance performance of the line printer.

  • Patent number: 5110227
    Abstract: A color printer according to the present invention includes a clutch means, an urging member and a positional alignment mechanism. The clutch means is used for engaging and disengaging a driving force used to move a paper holder means. The urging member (e.g., a spring) is used to urge the paper holder means in a direction opposite to the printing direction. The positional alignment mechanism is used for mechanically determining the position at which printing is to start on the paper when the paper holder means is disengaged from the driving force by the clutch means and is urged by the urging member in the direction opposite to the printing direction.

  • Patent number: 5062722
    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.

  • Patent number: 5049900
    Abstract: An apparatus is provided for scanning a photographic film or the like with a laser beam. The apparatus includes a roll source or cassette of film to be supplied and used and a take-up cassette to receive the exposed film in the form of a roll. Between the source of the film and the take-up cassette there is provided an arrangement consisting of one or two knurled segments or rollers which peripherally engage the film along the lateral edges thereof in order to transport the film past a laser beam generator and scanner adjacent which the knurled roller or rollers are positioned in order to draw the film at a closely controlled rate past a slot through which the laser beam exits in order to photographically process the film. Between the knurled roller or rollers and the take-up cassette are provided exit rollers which engage the film at a slightly faster speed than the speed at which the film is travelling. The exit rollers are arranged to engage the film with a force of about 21/2-4 pounds.

  • Patent number: 4999649
    Abstract: The device includes a record paper conveying device which rotates around a record paper carrier body to convey a paper sheet around the carrier body by gripping the leading edge of the paper sheet. In this arrangement, the carrier body, against which a recording head abuts during a recording operation, is rotated following the movement of the paper sheet by a friction force between the platen part and the recording paper sheet. In one embodiment, the carrier body is stationary, and accordingly, the conveying speed of the record paper sheet is determined only by the drive speed of the conveying device so that the record paper sheet can be precisely conveyed.

  • Patent number: 4971467
    Abstract: In a printer for printing information onto a recording medium, rotation of a platen in a normal direction causes the recording medium to be transported in a normal-feed direction. Rotation of the platen in a reverse direction causes the recording medium to be transported in a reverse-feed direction opposite to the normal-feed direction. Discharge rollers are arranged above the platen for rotation about an axis parallel to a longitudinal axis of the platen at respective peripheral speeds higher than that of the platen. A rotation transmitting mechanism is arranged between the platen and the discharge rollers for transmitting rotation of the platen to the discharge rollers.

  • Patent number: 4968164
    Abstract: A printing assembly which is adapted for printing on a print medium in a m of a sheet or tape includes a printing cylinder on which is wound and urged the print medium during a printing operation. A printing device prints on the print medium and urges it against the printing cylinder. An advancing device upstream of the printing device serves to advance the print medium and a tensioning device downstream of the printing devices tightens the print medium against the printing cylinder. The tensioning device includes two contra-rotating rollers having substantially smooth outer surfaces in contact from opposite sides of the print medium which allow sliding at the contacting surfaces and which provide for tensioning of the print medium on the print cylinder. The rollers are of the same diameter and are both motorpowered and driven at the same rotational velocity, which rotational velocity is greater than the advance velocity of the advancing device.
