The paper holder described in the above-mentioned patent document can be placed on a table and can be carried, but disassembling and assembling the paper holder itself is not easy, and even if it is possible to disassemble and assemble, tools are required. .
Therefore, the volume of the paper holder during transportation becomes even larger than the volume in the assembled state, and the transportation cost inevitably increases. Also, if the paper holder is disassembled to reduce the volume, the transportation cost will be reduced, but in that case the purchaser will have to assemble it at home, etc., and tools for that will be required, and the manufacturer will have to include the tool for assembling the paper holder. There is
Once such tools are assembled, they are no longer needed and are discarded. Therefore, the cost of the tools is lost and, in the end, the global environment is burdened.

In view of the problems of such conventional devices, the present invention realizes a desktop paper holder that can be easily assembled and disassembled without the use of tools, and is disassembled for transportation to make it compact and reduce transportation costs. It eliminates waste and considers the global environment.
