PURPOSE:To enable recording images of good quality to be obtained with a simple construction by changing the moving speed of a scanning system or photoreceptor according to the change of magnifications. CONSTITUTION:An image scanning system for exposing the subject in slit form, a first means which drives a photoreceptor by a commercial power source, a second means which drives the image scanning system mechanically independently from the first means, a means for setting projection magnification to the subject to be projected to the photoreceptor, a means which generates the signal for driving the second means and a means which controls the signal generating means according to the preset projection magnification by a setting means and changes the driving speed of the second means, are provided. As a result, the recording images of good quality may be obtained. |
