Abstract

PURPOSE: To obtain the titled system which can print only by exchanging wheels and switching control signals even when the number of types contained in a wheel is different, by a method wherein a multiplication circuit which can convert the required rotation frequency of types into a step number corresponding to the kind of wheel, is equipped.
CONSTITUTION: A multiplication circuit 21 is installed at the previous stage of a substraction counter 11, and a multiplier is changed-over according to the kind of wheel by a type number switching circuit 20 and further, the switching timing of the speed specification value from the counter 11 is changed-over according to the kind of wheel, and together with this, the analog quantity of a DA converter 12 is also changed-over. If the required rotation frequency N of a wheel is set initially in the circuit 21, the circuit 20 changes over the multiplier a of the circuit 21 according to the kind of wheel. (The multiplier a is 4 when the wheel is of 96 character wheel, and it is 3 when the wheel is a 128 character wheel.)
