ABSTRACT:
An apparatus for changing the direction of travel of sheets of paper being conveyed seriatim along a paper path without changing the orientation of the sheets with respect to a first direction of travel, comprises a deck having an upstream end for receiving a sheet being conveyed along a paper path in a first direction. There are a plurality of first roller pairs operatively coupled to the deck and disposed in a second direction for seizing a first leading edge of the sheet and conveying the sheet in the second direction along the deck. The second direction forms an acute angle of at most 45.degree. with the first direction. There are guide stucture operatively coupled to the first roller pairs for preventing portions of the sheet from raising off the deck when the portions are not controlled by the first roller pairs. A plurality of second roller pairs are operatively coupled to the deck and disposed in a third direction for seizing a second leading edge of the sheet and conveying the sheet in the third direction along the deck. The third direction forms a right angle with the first direction. The first and second roller pairs include lower driven rollers and upper biased rollers. The guide stucture includes a plurality of spring stucture for preventing portions of the sheet from lifting off the deck when being conveyed at high speed. The present invention is suitable for conveying sheets landscape to portrait or portrait to landscape.
