<p>A sheet feed/discharge roller mechanism (15) that includes a plurality of driving rollers (1) and a driven roller shaft (4) disposed in the roller mechanism (15) that is freely displaceable to the driving rollers (1). A plurality of driven rollers (5) are mounted on the driven roller shaft (4) in facing relationship with the driving rollers (1). A plurality of roller supporting members (7) apply forces to the driven roller shaft (4) for biasing the driven rollers (5) towards the driving rollers (1). The forces applied to at least one of the driven rollers (5) is greater than the forces applied to at least a second driven roller (5). <IMAGE></p> |
