In a word processor having a keyboard and a display unit for the one-line display of a succession of characters constituting a section of text, the display unit presenting a row of display locations each arranged to display one character, with the display location at the right end of the row constituting a character input location, each character keyed in via the keyboard being first displayed at the input location and then being displayed at successive locations extending along the row to the left of the input location upon the keying in of subsequent characters via the keyboard, the word processor further including a data memory connected for storing the characters keyed in via the keyboard, and a control device for controlling the display of stored text on the display unit, the display unit presents a second character input location to the left of the first-mentioned input location, and the processor is provided with control elements for causing the second location to become the operative input location so that characters keyed in via the keyboard are first displayed at the second location when the characters being displayed on the unit are derived from the data memory.

One line text display with two input locations

Plural imprints of a selected character on a record carrier medium, which imprints are close together, mutually offset and partially overlapping, are generated in an office machine printer equipped with a typing element, in order to correct misprints or produce bold face prints. The printer is arranged to produce lines of typed characters, and to effect relative movement along a typing line between the typing element and the record carrier medium, by a sequence of operations composed of: effecting an initial relative movement between the typing element and the record carrier medium in a first direction along the printing line to an initial position, and generating at least one imprint of the selected character; effecting a second relative movement between the typing element and the medium by a given number of elemental steps, which number is equal to at least one, each having a length which is a fraction of the spacing between successive characters on a typed line, in the first direction from the initial position to a second position; and effecting a third relative movement between the typing element and the medium by the same number of elemental steps as the second movement, in a second direction, opposite to the first direction, along the printing line, from the second position to a third position, and generating at least one further imprint of the selected character.
