Abstract
A sheet skew correcting apparatus, incorporated in a printer or the like to correct a phenomenon of obliquely feeding a sheet called skewing. The apparatus includes a transporting path in which the sheet is transported, a pair of registration rollers, a pair of timing rollers disposed upstream from the registration rollers, and a paper guide having a first and a second curved portion and constituting the transporting path. When a sheet fed into the transporting path abuts against a contact point of a registration roller pair, the sheet is further transported by an arbitrary distance in the sheet transporting direction. First and second curves are then formed in the sheet in the first and second curved portions. Then the registration roller pair is rotated in the direction opposite to the sheet transporting direction, the front end of the sheet uniformly abuts against the contact point of the registration roller pair to correct skew.
