ABSTRACT:
A data indicator unit having setting keys which control a setting stage connected in series with a switching unit that controls the energization of a series of optical character indicator devices, the number of switching states of the switching unit corresponding to the number of character indicating devices. Only one key need be provided which, to enter a selected character, can be actuated a number of times to set the setting stage accordingly to energize one of the character indicating devices corresponding to the selected character. Alternatively the key can be depressed for a selected period to effect entry of a selected character or a ten key keyboard may be provided to enter selected characters by depression of one, or a pair of keys, so that, for example, thirty two characters may be indicated by operation of only ten keys. The indicator unit may incorporate a ciphering/deciphering unit to encipher the selected characters and indicate its enciphered form.
