Abstract
PURPOSE:To facilitate maintenance, by setting the runway distance of one of plural home position sensors as a reference approach run distance. CONSTITUTION:When a distance between the home position sensors 19a-19c provided in the neighborhood of the start position of an original scanner at the time of performing unmagnified and enlargement copying and reduction copying, respectively, and the tip of an original is set, the runway distance from one (sensor for unmagnifying and enlargement copying, generally) of the home position sensors is set. Next, the distance between one position sensor and another position sensor is measured at the initial operation of the titled variable power copying machine or at every turning on of a main switch, and the said distance is added on the reference runway distance, then, the runway distance of another home position sensor is set. In such a way, it is possible to calculate the runway distance following up the secular change of a device, and to facilitate the maintenance.
