Abstract
An original feeding device for feeding OHP originals to the display stage of an overhead projector is capable of transportation control suitable for OHP projection. The originals are transported by a conveying film onto the display stage. In order to stop the original at the center of the display stage, after the original is detected by the registration sensor, the conveying film is advanced by an amount equal to the sum of the distance from the registration sensor to the display stage, a half of the length of the display stage and a half of the length of the original.
