PURPOSE:To attain to simplify operational processing by attaining to shorten the operational processing time for the positional control of each printing part, by preparing a number of the data relating to the positional informations of printing parts corresponding to the number of the printing parts. CONSTITUTION:CPU 22 compares the content S1 of the first position memory region 24a storing the printing positions S1 of a first printing part 6 with the printing position Sx printed on the basis of type data from now to calculate the moving direction and moving quantity L(=Sx-S1) of the first printing part 6. Subsequently, CPU 22 outputs a driving control signal to a drive circuit 32 to apply driving control to a carriage driving motor 33 and allows a carriage, that is, the first printing part 6 to move to said printing position Sx. During this movement, CPU 22 operates a printing position where the first printing part 6 moves and passes each occasion on the basis of the driving control signal thereof to succeedingly rewrite the content S1 of the first position memory region 24a. At this time, the content S2(=S1-St) of the second position memory region 24b storing the printing position at that time of the second printing part 7 arranged so as to provide a definite interval St from the first printing part 6 is rewritten in the same way. |
