An automatic document feeder having a 2-in-1 mode which serially locates first and second documents adjacent to one another at a copying position. The document feeder includes a separating part for separating documents one by one from a bundle of documents, a document feeding part for feeding documents at a speed which is faster than the transport speed provided by a document transporting part, with the transporting part located downstream from the feeding part. Since the feeding speed is faster than the speed of the transporting part, a space controlling part is provided for controlling a space between the first and second documents, such that after said space controlling part achieves a spacing of a predetermined distance, the document feeding part and the document transporting part transport the first and second documents and the first and second documents are placed serially on the contact glass without any undesired or excessive spacing between the first and second documents.
