ABSTRACT:
A paper path switching mechanism including a plurality of feeding rollers which feed a page when the page is pressed against the feeding rollers by guide members of a switching guide. The switching guide has long guide members which press the paper against the feeding rollers and short guide members positioned near the edges of the page. The short guide members guide the page without imparting too much resistance at the edges of the page in order to reduce the frequency of paper jams. The longer guide members are tapered in width at portions near the periphery of the feeding rollers in order to reduce the size of the contact area of the page to the long guide members which reduces resistance on the page and consequently reduces paper jams. After the page passes between the switching guide and feeding rollers, its direction of travel is reversed and the page again contacts the switching guide but moves along a different edge of the guide members and along a different paper path in order to invert pages.
