Claims

[Claims for Utility Model Registration] 1. A box-shaped frame with a pair of side walls erected at both left and right ends, a rotating shaft mounted within the frame with both ends rotatably inserted through the both walls, and the frame. a pair of holders provided within the holder to be slidable in the axial direction of the rotating shaft; and a pair of sprockets provided within the holder to be rotatable integrally with the rotating shaft and slidable in the axial direction thereof. The holder has a hole on both left and right sides through which the rotating shaft is inserted, and a groove for accommodating the sprocket wheel so that a part of its outer periphery is exposed. A paper feeding device characterized in that a portion of the outer surface of the box-shaped frame is brought into contact with the inner surface of the box-shaped frame so as not to rotate around the rotating shaft and to be slidable in the axial direction thereof. 2. The box-like frame has a bottom wall, and the holder has a box-like shape with a groove facing downward and opening;
The paper feeding device according to claim 1, wherein the sprocket wheel can be inserted into and removed from the holder through its open surface, and the open surface faces the bottom wall. 3. The sprocket wheel has a boss sleeve part that fits into the rotating shaft, and the groove in the holder has a downwardly open notch on both sides that rotatably holds the boss sleeve part.Registered as a utility model. A paper feeding device according to claim 2.
