Abstract:
A sheet inversion device for reversing the surfaces of a sheet that has been fed into said sheet inversion device, comprising:a first roller, located at the start of an inversion path in the direction in which a sheet is input or output along said inversion path, that rotates in only one direction; a second roller, arranged parallel to said first rollers, that rotates with said first roller so as to feed said sheet into said inversion path; a third roller, located in parallel to said first rollers on the opposite side of said first rollers from said second rollers, that rotates with said first rollers to feed out and discharge said sheet from said inversion path; a fourth roller, located inside said inversion path, for applying a feeding force, in a discharge direction relative to a sheet feeding force applied by said first and second rollers, that causes said fourth rollers to slip across said sheet; and a pressing and guide member, for applying, with said fourth roller, a sheet pressing force that resists the advance of a sheet that is being fed; wherein a pressing face of said pressing and guide member has the same arced shape as has the circumferential outer face of said fourth roller.
