Claims

[Scope of Claim for Utility Model Registration] (1) In a paper conveyance roller that conveys paper between the driven rollers and the driving roller, each of which has rollers inserted in a skewered manner on one shaft, the rollers are brought into pressure contact with each other, and the above-mentioned A paper conveyance roller characterized in that the roller of the driven roller is divided into at least two layers, an inner part and an outer peripheral part, the inner peripheral surface is an elastically deformable layer, and the outer peripheral part is a low friction coefficient ring. . (2) The paper conveying roller according to claim 1, wherein the inner diameter of the outer ring is larger than the outer diameter of the inner circumferential surface. (3) Taper the outer diameter of the ring on the outer periphery so that it is larger on both ends than on the center side of the paper conveyance width, and attach a retainer ring to the shaft at an appropriate distance from both end surfaces of the roller and ring. A paper conveyance roller according to claim 2 of the utility model registration claim. (4) A retainer ring is provided on the shaft in close contact with the end surface on the center side of the paper transport width of the internal elastically deformable layer of the roller of the driven roller, and a retainer ring is provided at an appropriate distance from the opposite end surface. , and the two retainer rings are provided at a distance from both end surfaces of the rings, the paper conveyance roller according to claim 2, which is a registered utility model.
