A data input system useful in a data base such as an address data management system. This data input system can reduce the number of key operation and the possibility of erroneously inputting data. This system comprises: a display for displaying input data; a first memory for storing data displayed on the display, a second memory for temporarily storing the displayed data; and a control unit for displaying the data stored in the second memory.

Data input system with automatic duplication of repetitive data to a

A word processing apparatus includes a random access memory for temporarily storing the document data, and a floppy disc for permanently memorizing the document data. A character number counter is included in the word processing apparatus, which develops a control signal when, for example, 100 stroke key input operation is conducted through a keyboard panel. In response to the control signal, the document data temporarily stored in the random access memory is transferred to the floppy disc for updating the document data memorized in the floppy disc.

System for transferring document data to non-volatile memory in a word

The data processing terminal unit in the form of a point of sale transaction device disclosed herein contains a keyboard for introducing data into the data processing terminal unit and a cassette tape deck which includes a cassette type magnetic tape and a cassette tape recording scheme for data storage. There are provided an E key and an M key on the keyboard for introducing end marking signals (EM signals) which indicates completion of data entry. The EM signals are introduced into the data processing terminal unit when the E key and the M key are depressed successively or simultaneously, thereby preventing erroneous introduction of the EM signals at an undesired time.
