ABSTRACT:
The present invention is directed to the provision of a sheet feeder unit mounted in a copying machine or the like having a sheet transport mechanism. The sheet feeder unit feeds sheets to the sheet transport mechanism, and the sheets fed into the sheet transport mechanism are transported by the sheet transport mechanism. Each sheet being transported by the sheet transport mechanism is detected by a pair of sensors disposed with a prescribed space provided between each other, and the sheet transporting speed is calculated from the time in which the sheet travels the distance between the two sensors. The sheet feeding condition is set on the basis of the sheet transporting speed of the sheet feeder unit so that the sheets fed from the sheet feeder unit do not overlap each other.
