ABSTRACT:
A device for changing a passageway for paper includes flaps pivotably provided at branching points of the passageway and operable to change the paper feeding direction. Solenoids mounted with shafts are extended by first springs during non-energizing and retract during energizing, and second springs are provided for imparting biasing forces to follow the displacement of the shafts and to pivotably bias the flaps so that the flaps receive rotational moments of force acting in opposite directions in the energizing and non-energizing states, the rotational moment of force being set so as not to hinder the feed of the paper.
