Abstract: 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.
