Abstract
This invention relates to a device for controlling the activation of moving elements, such as for example an ink jet type print-head or a sensor of equipment for scanning text and/or images. The device, upon the measurement by means of, for example, the moving element to travel the step P, and the basis of selectively predefined numerical values associated through the control circuit with the time T(p), permits division of the step (p) into a number of n of elementary steps P/n uniformly distributed through the step P, including for high values of the number n. Accordingly by means of the device it is possible to obtain considerable uniform printing or scanning under all conditions and, in particular, when the resolution, which depends on the value of the number n, has to be at its maximum.
