Abstract
A number-of-pulses correction value corresponding to non-uniformity in conveyance appearing during one circulation of a conveying roller is held in a number-of-pulses correction value storing section 32. A control section 33 produces the target number of pulses (a real number) in the printing position at the destination of one line feed on the basis of the number-of-pulses correction value, and the target number of pulses (a real number) in the printing position at the destination of the line feed is changed into an integer, and the pulses whose number is an integer are fed to a pulse motor 11, to control the amount of rotation of the pulse motor 11. Further, the control section 33 corrects the target number of pulses in the printing position at the current time point in correspondence to the fact that the pulses whose number is not a real number but an integer are fed to the motor. Consequently, it is possible to reduce the occurrence of non-uniformity in a pitch between lines.
