摘要： A buckling type paper sheet feeding mechanism wherein the top sheet of a stack is separated from the underlying sheet by first driving the front sheet edge in a rearward direction against a rear restraint, causing the top sheet to buckle, and then reversing the direction of sheet drive, causing the top sheet to be fed in a forward direction over a front stack edge restraining or hold-down means. The top sheet is moved rearward by a variable force means which provides a progressively increasing buckling force, to thereby ensure reliable feed of paper of varying types, weights and humidity content, while at the same time minimizing the possibility of double sheet feed. A variable position rear restraint moves rearward, in synchronism with operation of the variable force means, to increase the column length of the top sheet as the buckling force increases.

摘要： A method of making a plurality of multi-wire nonimpact printheads provides precise inter-wire spacing accuracy and repeatability of manufacturing steps to enable mass production.A plurality of slats are molded, one alongside another on a cylindrical support shell, parallel to the shell axis. A helical thread is engraved on the slats along the axial length of the support shell. A continuous wire is wrapped in the thread and the portions of the wire on the slats are encapsulated. The support shell and wrapped wire is cut between adjacent slats to obtain a plurality of printhead blanks. Each blank is machined to smooth the exposed print wires. The resultant printheads may be used in page- width nonimpact printers.

摘要： In a thermal printer the transfer ribbon such as one having sets of transverse color stripes is guided over of a ribbon support which carries the heat applying print head. The ribbon support is movable relative to the paper by an eccentric to move the ribbon into and out of contact with the paper. A support beam and a guiding roller are provided immediately behind print area to guide the ribbon away from the paper path in an angle of more than 45 degrees. This assures a separation of the ribbon from the paper essentially normal to its surface, thus avoiding shear upon relative movement between paper and ribbon and negates the need for a relatively bulky ribbon carrier material. Color printing is performed by clamping paper and ribbon, applying heat, transferring color material, retracting the ribbon from the paper, advancing the ribbon to the next color area, printing again on the very same paper area as often as desired, repeating this as often as necessary and advancing the paper after finishing the present print line.

摘要： Mechanism for separating the uppermost pliant sheet of a stack of such sheets from the stack including a rotatable friction drive wheel effective on the longitudinal center line of the uppermost sheet for initially moving the sheet rearwardly, and a pair of downwardly tapered posts at the rear face of the stack and on opposite sides of the center line which cause the uppermost sheet to bow upwardly away from the stack particularly on its side edges for thereby effectively separating the sheet from the stack and allowing it to be driven subsequently in the forward direction to free it completely from the stack.

摘要： A plurality of arrays of heating elements, forming printing zones, are arranged separated from each other a predetermined distance (SL) on a substrate along a line (X) transverse the media transport direction (Y). The heating elements in each zone are arranged parallel to the transport direction (Y). Mover elements sweep the head back and forth relative to print line, a distance of SL. Releasable backing element is formed by rollers and each printing zone, the length of which is SL, is associated with a roller. The backing-rollers are moved together with the head for urging the print media against the thermal transfer ribbon and the latter against the multi-zone thermal print head.

摘要： In a conventional ribbon supply spool structure which comprises a supply of ribbon wound on a hub rotatable about and axially movable with respect to a hub receiving member on which the hub is seated and which is coaxial with respect to the hub, an improved end of ribbon detection device is provided by the combination of deflectable spring means within the spool hub which exert a force when deflected having a first force component acting against but restrained by wound ribbon on the hub and a second component acting along the hub axis. A spring tensioned member exerts a force along the hub axis which opposes the component of force of the deflectable spring along the hub axis. In this manner, the deflectable spring and the spring tensioned member are maintained in static equilibrium at a selected point along said axis so long as the deflectable spring is restrained by a predetermined minimum of ribbon remaining wound on the hub. This predetermimned minimum of ribbon remaining wound is indicative of the end of ribbon. In the preferred embodiment this is in effect the point where the ribbon becomes substantially unwound.
