ABSTRACT:
A recording typewriter of the type including a memory arranged to record codes corresponding to typed characters as they are typed, and to drive the typewriter to type characters corresponding to stored codes. A single line readout is provided, preferably positioned between the typewriter keyboard and roller so as to be easily accessible to the view of an operator. The readout displays a selected line of characters as recorded in the memory. The particular line to be displayed is selected in dependence upon the typewriter elements associated with line control, such as the position or change of position of the typewriter roller or the actuation of the carriage return control. The system provides an economical and effective means of accessing stored data, allowing correction of stored documents, for example, to be easily accomplished.
