Abstract

PURPOSE: To make a reduced copy of the original possible, by electrically processing image signals and varying the subscanning speed when recording.
CONSTITUTION: By means of the driving mechanism driven by a motor M, an image sensor IS and the original are moved at specified relative speed in the subscanning direction. In this state, the image signal being output from the sensor IS is applied to a signal processing circuit SC through a read-out amplifier A. In the processing circuit SC, every two adjacent picture elements in the main scanning direction and every two adjacent picture elements in the subscanning direction are individually processed to be made into signle picture elements to generate a picture signal, which is output to an outputed terminal O. When this picture signal is recorded in a recording device in which the moving speed of the recording paper in the subscanning direction is 1/2 of the moving speed of the original when reading the original, an image reduced to 1/2 is recorded. Thus, reduced copies may be made easily.
