ABSTRACT:
In an image processing apparatus, when a copying operation is to be conducted with a scanner and a printer having different read speed and record speed, a read document sheet feed unit having two document sheet feed speeds, one synchronized with a read interval of the image sensor and the other synchronous with a print interval of the pointer, a signal generation unit for generating a read suppress signal at a predetermined time interval and a read suppress unit for suppressing the reading of the image sensor in accordance with the read suppress signal are provided. Thus, an the copy mode, the read document sheet is fed at a speed equal to the printer speed and the image read by the image sensor is thinned so that the copy operation is attained without deterioration of image quality with a small capacity of buffer memory and simple control.
