Abstract
A sheet detection system comprising: a first sheet transport for transporting a sheet along a first sheet transport path; at least second and third sheet transports for selectively transporting a sheet transported along the first sheet transport path along second and third spaced and substantially parallel sheet transport paths which branch from the first sheet transport path; a radiation source for emitting a beam of radiation which intersects the second and third sheet transport paths in the region where the second and third paths branch from the first path; a radiation detector for detecting the radiation beam; and a control for controlling the first, second and third sheet transports the radiation source and the radiation detector, such that when a sheet which is transported along the first sheet transport path by the first sheet transport is caused to be transported along one of the second or third transport paths, interruption or lack of interruption of the radiation beam by the sheet is detected by the radiation detector to indicate whether the sheet has or has not been transported along the one path.
