Abstract (en)
[origin: EP0156359A2] An electronic typewriter has a keyboard (2) including a plurality of character keys (8, 9), a printing wheel (5) having a plurality of types which can be designated by the character keys (8, 9), a ribbon position setting circuit (18) for selectively setting a printing ribbon (6) at either one of printing or rest positions, and a control circuit (12) which supplies a first control signal to the ribbon position setting circuit (18) so that the printing ribbon (6) is set at the printing position and thereafter the type designated by one of the operated character keys strikes a paper sheet through the printing ribbon (6) when one of the character keys (8, 9) is detected to have been operated while the printing ribbon (6) is set at the rest position, and which supplies a second control signal to the ribbon position setting circuit (18) so as to set the printing ribbon (6) at the rest position when no further key operation is detected for a preset holding time after the printing by one of the character keys is ended. The electronic typewriter further has a holding time data generator (15) for generating holding time data which is used to determine the preset holding time and can be arbitrarily changed.
