Filed: 1985-08-10
Abstract: PURPOSE:To attain a color picture without color deviation by controlling the scanning speed of an original scanning unit depending on the scanning position of an original scanning unit or the scanning time so as to minimize the position deviation of the stop position of the original scanning unit. CONSTITUTION:The original scanning unit 21 starts the scanning from a home position HP and starts moving toward the original tip position DTOP. The number of signals D6 required to move a distance (l) from the home position HP to the original tip position DTOP is obtained in advance so as to allow the original scanning unit 21 to reach an object speed v1 before the original tip DTOP thereby reaching the unit to the object speed v1 with a pulse number smaller than the number of the signals D6. If a stepping motor is started at the rapid number of revolutions from the starting, then the delay of the drive system or its fluctuation is caused, thus the stepping motor rises gradually stepwise from the sufficiently low number of revolutions up to the object number of revolution n1. Then the moving speed of the original scanning unit 21 is raised gradually stepwise shown in figure.
