Abstract
A parallel transport apparatus for transporting sheets side by side along a plurality of transport paths is provided with a feed roller which is brought into contact with uppermost sheets of a plurality of stacks of sheet contained side by side in a cassette and is adapted for feeding the uppermost sheets side by side; a separation roller pair arranged at a specified position of each of the plurality of transport paths and adapted for separating the sheets fed side by side so that one each of sheets are transported along the respective transport paths simultaneously; a sheet detector arranged downstream from the separation roller pair with respect to a sheet transport direction and adapted for detecting the presence or absence of sheets being transported side by side; and a multifeed discriminator for discriminating whether the multiple feeding has been occurred along any of the transport paths in accordance with an output from the sheet detector. Accordingly, the multiple feeding of sheets being transported side by side can be detected and coped with automatically.
