PURPOSE:To increase a printing speed and to make the variation of load for carriage driving system small by making the carriage to be not stopped even though during a selected letter on a daisy wheel being printed by a hammer. CONSTITUTION:It is operated that how many rotation time (to) is necessary for a letter taked out from a character buffer. A daisy wheel and a carriage are revolved when a displacement time for one letter pitch of the carriage is set to To which is larger a little than the rotation time (to) of the daisy wheel. And the letters are printed on a blank when the displacement of the daisy wheel is confirmed in the first place. Then, the rotation time (to) on the daisy wheel until a type of the letter to be printed next again is calculated after a printing by a hammer is completed, and the carriage is displaced by one letter pitch with the time To which is a little larger than this rotation time (to). In this manner, the printing speed can be increased broadly owing to a continuous displacement of the carriage without an interruption. |
