Paper conveyance apparatus for an image forming apparatus and a method thereof

摘要

A paper conveyance apparatus and method for an image forming apparatus are disclosed. The paper conveyance apparatus and method provide an improved structure in which when the distance between the conveyance roller shaft and the reversible roller shaft is shortened due to the abrasion of the reversible roller, the center of a gear train which transmits a driving force to the reversible roller is swung to move as much as the shortened distance so that the reversible roller can be continuously in contact with the conveyance roller. The paper conveyance apparatus and method comprise a conveyance roller for conveying a paper sheet to an image forming section, a reversible roller for contacting the conveyance roller, a driving motor having a driving gear for supplying a driving force to the reversible roller, and an idle gear for transmitting a driving force from the driving motor to the reversible roller. The center of rotation of the idle gear is movable according to the degree of abrasion of the reversible roller in order to transmit a driving force from the driving motor to the reversible roller.
