Abstract

PURPOSE: To enable ribbon-feeding of enough quantity as well as printing of high quality through early start-up of a motor by driving the same with a larger value of a driving current or longer continuation of time thereof than usual value immediately after a printing instruction is given.
CONSTITUTION: In case when a machine-ready signal is kept impressed on an information-interval supervising circuit SCC, the presence of the machine-ready signal is checked on the start-up of flip-flop (FF) according to the start-up of a machine-ready signal A. And the presence is judged to indicate that the printing is being operated, while the absence being judged to indicate that the printing stops, and, based on the judgement, either a strongly exciting circuit SEC or a weakly exciting circuit WEC is selected at an excitation designating circuit EDC. When the judgement is made by the excitation designating circuit EDC, an excitation designating signal C is given and the strongly exciting circuit SEC is selected, which prepares for driving a motor M through an amplification circuit AMP. On a subsequent machine-ready signal starting up, an exciting current as D is impressed on the motor M. The excitation designating signal disappears on the subsequent excitation-judging signal starting up, and the weakly exciting circuit WEC drives the motor M.
