Abstract: An apparatus for controlling the transportation speed of a sheet, such as a printed sheet or manuscript, includes a sheet transportation system and a speed controller. The transportation system includes a single drive motor and a plurality of rollers driven by the single motor and arranged in such a manner that a sheet to be transported is held by the rollers one after another. The speed controller includes a sensor for detecting the position of the sheet. The number of rollers which hold the sheet is determined. A speed controller provides the motor with a designated speed command calculated on the basis of the numbers of rollers, so that the actual sheet transportation speed is always constant regardless of the numbers of rollers which hold the sheet.
