Binder

摘要

A binder with the plurality of binding portions (curl rings, etc.) has indication(s) such as projection, hollow, paint, etc. at each end of the binder or both ends thereof enabling users to quickly and simply identify a direction of the binder to bind papers without errors. Users can identify the binding direction only through visibly or tactilely confirming the indication(s) thus improving efficiency of binding operations. <IMAGE>
