摘要： A cassette type ink ribbon device comprises a pair of cassette cases mountable in spaced-apart non-touching relation on a printing apparatus. An endless ink ribbon extends through the pair of cassette cases. A transfer roller and an ink roller are both rotatably mounted within one of the cassette cases and are in contact with one another to replenish ink onto the ink ribbon. A slidable tensioner is disposed within the other cassette case for applying a tensioning force to the ink ribbon. The tensioner comprises a slidable guide body having a guiding surface portion in sliding contact with the inner side of the ink ribbon, a slideway within the other cassette case for slidably supporting the guide body, and a biasing spring disposed within the other cassette case for biasing the guide body along the slideway to apply a tensioning force to the ink ribbon. By such a construction, minor variations in the spacing distance between the pair of cassette cases when mounting the cassette cases on the printing apparatus can be accommodated by sliding movement of the guide body.

摘要： A printing head adapted to be moved for scanning in a direction perpendicular to the direction of feed of a paper is provided with a sole printing element (printing hammer) adapted to be driven in an impacting manner by an electromagnetic driving device. A platen disposed to oppose to the printing head is provided with a plurality of projections formed on the outer peripheral surface thereof and extending substantially in parallel with the axis thereof. Each of the projections being adapted to oppose to the printing element in a crossing relation to the latter when it is brought to the position ahead of the printing element as a result of rotation of the platen. As the printing element collides with the projection while the platen is rotated, a dot is formed on the recording paper at the position of crossing between the printing element and the projection, so that various patterns such as letters, numerals, symbols, pictures and so forth are printed at a high speed by a sole printing element.

摘要： A cassette type ink ribbon device for use in printing apparatus comprises a pair of cassette cases releasably connected together by mutually engaging pawls. The connected together cassette cases contain ink and transfer rollers for inking an ink ribbon, and a tensioner for applying a tensioning force to the ink ribbon. The tensioner comprises a slidable guide body having a cavity in which the slack part of the ink ribbon is stored, and a biasing spring which biases the guide body in a direction to apply the tensioning force to the ink ribbon. Both cassette cases may have the same shape and configuration thereby simplifying manufacturing costs.

摘要： A printer is capable of stably feeding even a thin recording medium to a printing section and obtaining good print quality similar to that obtainable in the case of a thick recording medium. The printer comprises a first supply path for supplying a first recording medium, a second supply path for supplying a second recording medium thicker than the first recording medium, a printing section for printing on a recording medium supplied from the first supply path or the second supply path, and a delivery section for delivering the recording medium printed in the printing section. A guide spring member which is movable up and down is projected upstream of the printing section and in a meeting portion of the first supply path and the second supply path. This guide spring member serves to support a top surface of the first recording medium at a predetermined height.

摘要： A paper tractor for feeding paper of different widths in printers and the like comprises a rotationally driven shaft having mounted thereon a sprocket wheel which engages in perforations in a length of paper to effect lengthwise feeding of the paper in response to rotation of the sprocket wheel. The sprocket wheel is mounted on the drive shaft to undergo rotational movement therewith and is mounted on the drive shaft to undergo axial sliding movement therealong to enable axial positioning of the sprocket wheel to accommodate paper of different widths. The drive shaft has a polygonal cross-section, and the sprocket wheel has a center tubular sleeve formed of plastic and configured to be slideably inserted over the drive shaft so that rotational movement of the drive shaft is transmitted to the sprocket wheel. The tubular sleeve is provided with a set of axially extending grooves which render the sleeve radially resilient so that the sleeve frictionally engages with the drive shaft with a frictional force-fit which is effective to maintain the sprocket wheel in a preselected axial position during rotational movement thereof yet which permits the sprocket wheel to be manually slid along the drive shaft so as to easily adjust the axial position of the sprocket wheel to thereby enable the feeding of paper of different widths.
