PURPOSE:To decrease speed difference between lines by providing an operation section calculating a feeding speed of a prescribed line and controlling a speed of a step motor for feeding paper in response to an output of this operation section so as to uniform the feeding in one line. CONSTITUTION:Black dot numbers of one line are counted by a dot counter 10 and the data are fed to a time operation section 11. The operation section 11 calculates the recording time of one line based on the number of black dots inputted and the time is fed to a pulse operation section 12. The pulse operation section 12 divides the inputted recording time by motor pulse number for one line's share, the quotient is fed to a counter 13 and the motor pulse number is fed to a counter 14. The counter 13 counts a transmitted operating value and gives a motor pulse to a step motor 15 and the counter 14. The counter 14 outputs a reset signal to the time operation section 11 when the number of pulses transmitted from the operating section 12 and the pulse number transmitted from the counter 13 are coincident. |
