Abstract
Abstract The typewriter has a keyboard (11), a printing device (15) and a control unit (16) which includes a real time integrated circuit (23) adapted to provide the functions of clock and calendar. The date can be inserted as a variable component in constant sentences, which are stored in a non-volatile memory dar. The date can be inserted as a variable component in con(22) for being printed afterwards at the operator's command. The typewriter includes a display (12) where, at the operator's requent and/or automatically, the time and the date generated by the real time circuit (23) are displayed.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
77 words
An electronic typewriter comprising a keyboard (11), a printing device (15), a control unit (16) with a non-volatile memory (22) wherein constant sentences can be stored for being printed afterwards by the printing device at the operator's command, characterised by a real time electronic circuit (23) adapted to generate continuously data indicative of the time and/or the date, and in that these data are transferred into the non-volatile memory (22) as variable components of the constant sentences.
Claim 2
Dependent Claim
77 words
An electronic typewriter comprising a keyboard (11), a printing device (15), a control unit (16) with a non-volatile memory (22) wherein constant sentences can be stored for being printed afterwards by the printing device at the operator's command, characterised by a real time electronic circuit (23) adapted to generate continuously data indicative of the time and/or the date, and in that these data are transferred into the non-volatile memory (22) as variable components of the constant sentences.
Claim 3
Dependent Claim
30 words
A typewriter according to claim 1, characterised in that the display (12) is adapted to display in a selective way the data generated by the real time electronic circuit (23).
Claim 4
Dependent Claim
40 words
A typewriter according to claim 1 or 2, wherein a back-up battery (30) is permanently connected to the non-volatile memory (22), characterised in that the back-up battery (30) is permanently connected also to the real time electronic circuit (23) .
Claim 5
Dependent Claim
47 words
A typewriter according to claim 1, 2 or 3, characterised in that the keyboard (11) includes a code key (40) which, when pressed together with predetermined alphanumerical keys (17) of the keyboard, modifies the sequence in which the date parameters are printed by the printing device (15).
Claim 6
Dependent Claim
50 words
A typewriter according to any of claims 1 to 4, characterised in that the parameter which shows the month of the date, can be entered in the memory (22) to enable that parameter to be printed in a selective way in characters or as the ordinal number of the month.
