Abstract
An apparatus for loading/unloading a drum member and a related method are described. The apparatus includes an inner support member slidably arranged between a center shaft fixed to a frame and a drum member. When the drum member is required to be unloaded from the frame, the inner support member is ejected along the center shaft for a predetermined length, and then the drum member is drawn out while using the inner support member as a guide. The method includes the steps of: providing a center shaft secured at one end to the frame; providing an inner support member slidably attached to the center shaft; providing a drum member supported at its inner surface by the inner support member and being slidable along the center shaft axis; drawing out the inner support member for a predetermined length toward the outside of the frame; and drawing out the drum member toward the outside of the frame, while using the inner support member as a guide. By this apparatus and method, the drum can be drawn out easily and safely while using the inner support member as a guide.
