Abstract:
A sheet member supply system in an image processing apparatus, provided with a hopper on which sheet members are piled, a supply roller for picking up said piled sheet members and feeding out the sheet members to an image processing system, a multi-transport preventing roller pair of a separation roller and a retard roller disposed on a downstream side of said supply roller and in an entrance to said image processing system, said hopper being movable with respect to said supply roller, said sheet member supply system comprising:a multi-transport detector, disposed on an immediate downstream side of said roller pair of the separation roller and the retard roller, for detecting multi-transport of said sheet members, and a controller that, when sheet member multi-transport is detected by said multi-transport detector, performs controls to first shift said hopper in a downward direction apart from said supply roller, and then to decrease a nipping force between said separation roller and the retard roller and increase a rotation torque of said retard roller.
