Abstract

A portable electronic word- processing unit comprises a manually operable input keyboard 2; an internal power supply 15, 18, 14; a display device 13; output means 16, 17 to enable the word-processing unit to be connected to a printer; and electronic components including memory means and a micro-processor mu P interconnected and programmed so as to receive from the keyboard signals corresponding to alpha-numeric characters and instructions for processing the characters, edit the character signals, feed signals to the display device for display of characters as an edited text, and store the edited text and print format instruction signals available for transmission through the output means. In a preferred embodiment, the keyboard has at least five keys and the micro- processor is programmed to record the signals produced by operation of any one key or a combination of up to a maximum of five keys to generate a coded signal representing a particular alpha-numeric character or processing instruction. <IMAGE>
