The single drive source drives the feed device and the loading device is driven through the feed device. A carrier having a carrier rack moved by the drive source and a carrier pinion meshing with the carrier rack are provided in a drive system for a loading pinion meshing with a disc case rack and the loading pinion is connected to the carrier pinion through clutch means.
