摘要：A loose leaf device comprises a plurality of assembly units and a plurality of sheets of papers. Each assembly unit has a round shape and a periphery of each assembly unit has an annular ring. A center of each assembly unit has a via hole and an inner ring is protruded from an inner wall of the annular ring. Each paper has a plurality of through holes and slots. Each through hole and each slot are correspondent to the annular ring of the assembly unit. Each slot of the paper is communicable to the outer side of the paper by a slit. The inner buckles are formed at the edges of the slot and outer stoppers are formed at the edges of the slit. Moreover, the paper can be replaced a plurality of thin pocket sheets, each sheet can receive photographs, compact disks, etc.
