The control of the analysis of the original image, applicable to a recording device of the type a slot of exposure.

摘要

P the invention relates to a system for controlling the analysis of the original image that can be used in a recording device of the image of the type a exposure by a slit. / p & & p & the system is characterizes in that it comprises an oscillator 21 serving to produce an output signal of frequency predetermined, a pulse counter 22 which receives the output signals of the oscillator and a database of the enlargement corresponding to a level of the enlargement of the image and which generates the pulses of the output of a frequency predetermined, a power amplifier 25 receiving the output pulses of the counter, and generating at its output a current of a frequency corresponding predetermined, and a synchronous motor 4 serving to perform the analysis of the original image when it is supplied by the current supplied by the power amplifier. / p & & p & application to the field of the printers, and the copiers. / p
