<p>PURPOSE:To prevent the occurrence of positional deviation in the case of superposing images by controlling and driving a driving motor for a conveying means and a photosensitive body by speedup and slowdown processing in terms of exponential function. CONSTITUTION:The device is provided with the driving motor 15A which is installd in the driving part of an endless belt-like transfer paper conveying means 11 and can normally and reversely rotate, and a control part 4 where the driving part of the motor 15A is connected to its output side and the driving direction and the driving time of the means 11 are inputted. The speed of the means 11 is controlled by the control part 4 by the speedup and the slowdown control in terms of exponential function. At such a time, the change of the speed of the motor 15A for the feeding belt becomes easy and vibration is prevented from occurring. Thus, the positional deviation in the case of superposing the images is prevented.</p> |
