摘要：
An apparatus (10) for detection of multiple documents (42) in a document transport system comprises a first transmitter (13) emitting a first signal at a first interval through a document feed path (40). A first sensor (14) detects the first signal from the first transmitter (13). A second transmitter (15) emits a second signal at a second interval through the document feed path (40). A second sensor (16) detects the second signal from the second transmitter (15).
