摘要： A cartridge for the inked ribbon of a calculating or other office machine, of the type comprising a platen, a plurality of printing styli disposed in front of the platen at a short distance therefrom, a motive shaft, two fixed stops for transverse positioning of the cartridge with respect to the platen and a longitudinal positioning block. The cartridge comprises a container of substantially parallelepipedal form having a larger side provided with a recess defining two lateral arms. An inked ribbon closed in a loop is disposed inside the container and extends therein between an inking roller and a ribbon tensioning element. The ribbon has a substantially rectilinear portion which emerges from the said lateral arms and spans the recess, parallel to the larger side. The inking roller is housed in a first of the lateral arms, is engageable by the motive shaft of the machine driving the ribbon, and has its diameter substantially equal to a smaller side of the container, while the ribbon tensioning element is housed in the second of the said lateral arms. Two abutment surfaces and a recess co-operate with the said fixed stops and the positioning block, respectively, when the cartridge is mounted on the machine in order to position the ribbon exactly with respect to the platen and the printing styli.

摘要： A device for controlling the rotary movement of a platen roller of a typewriter comprises a bidirectional electric motor coupled to the platen by a worm gear and gear wheel and a pair of knobs which are disposed at the sides of the platen and which are rotatable with respect thereto. The knobs are fixed to a bar which extends rotatably through the platen roller and carries the gear wheel. Selective bidirectional rotation of the knobs causes corresponding rotary movement of a disc in a transducer. The disc has a toothed sector in mesh with the gear wheel and is the moving part of a rotary switch which generates electrical signals which determine both the power supply to the electric motor and the direction of rotation thereof. Small degrees of rotary movement of the knobs against a first spring force establish continuous rotary movement of the platen roller at low speed. A further slight rotary movement of the knobs against a stronger spring force establishes rotary movement of the platen at high speed.

摘要： The device comprises two or more cover plate members (14), whose lengths are submultiples of the lengths of a range of platen rollers (12) and such that two or more plate members disposed in side-by-side relationship cover the entire length of the platen roller. Each plate member (14) comprises a lower guide portion (16) of part-cylindrical shape and two wall portions (17, 18) which are substantially planar and set at different angles of inclination, being connected to the lower guide portion in such a way to lead in a sheet of paper (19) towards the guide portion. Each plate member (14) is pivotally mounted on a control shaft (22) which is parallel to the axis of the roller (12) and capable of preventing transverse movements of the plate member with respect to the roller, and carries the usual paper pressing rollers (34, 36) which are disposed in two parallel rows. A leaf spring (26) co-operates with a lug (24) on the plate member (14) to hold the paper pressing rollers pressed against the platen roller. The control shaft comprises opening cams (57) arranged to co-operate with the leaf springs to disengage same from the respective lugs and to permit the respective plate members to drop away from the platen roller (12), whereby the paper pressing rollers (34, 36) are disengaged from the platen roller to assist in introducing the sheet of paper.

摘要： A device for inking the type-carrier element of a calculating machine or similar office machine. The type-carrier element includes a wheel from the edge of which protrudes corresponding characters. These are selected by a recording support for the rotation of the wheel and define the various writing positions for the movement of the wheel along a line of writing. The device includes a container with an ink-deposit element inside it and which has a long window substantially the same length as the line of writing and covered with a permeable, wear-resistant layer which is in contact with the deposit element in order to permit the outflow of the ink. A spring element keeps the said permeable layer tight against the type-carrier element during the rotation and movement of the wheel.
