Claims

[Claims for Utility Model Registration] 1. A roller shaft rotatably supported on the main body of a copying machine, etc., a roller main body externally fitted and fixed to the roller shaft, and a discontinuous roller removably attached to the roller main body. a rubber body, a pair of notched holes for engaging both ends of the rubber body are continuously formed in the roller main body, and the rubber body is fitted into the notched holes in a state where both ends are in contact with each other. A paper feed roller characterized by: 2 Consisting of a roller shaft rotatably supported by a main body of a copying machine, etc., a roller body externally fitted and fixed to the roller shaft, and a ring-shaped rubber body detachably attached to the roller body, The roller body includes a roller center portion into which the roller shaft is inserted, a roller outer peripheral portion into which the outer peripheral portion of the rubber body is fitted, and a connecting piece connecting the roller center portion and the roller outer peripheral portion on one side. A fitting hole into which a part of the rubber body is fitted is formed between the roller center part and the roller outer circumference part, and the rubber body avoids the roller center part to form the fitting hole and the roller outer circumference part. A paper feed roller, characterized in that it is engaged with.
