<p>PROBLEM TO BE SOLVED: To provide a writing instrument back face storage type bookbinding object of an easily-openable, cover-non-slackening and writing instrument-protective structure, since there are cases where a writing instrument-storable bookbinding object is hard to open, or slackening is caused in the cover back, or a bag is flawed in carrying, or a writing instrument is occasionally damaged.SOLUTION: Back cloth is adhered to the outer periphery of a writing instrument-storage pipe, and a back cloth-joined position is set as a fulcrum for moving a text, and play is made by sticking the back cloth from the text-moving fulcrum, and the back cloth is adhered by adjusting the play end to a central position of the text back, and an adhered central part is set as a fulcrum for adjusting a text- opening angle. A cover is adhered to a back position of the back cloth adhered to the pipe. The cover is provided with a groove to serve as a fulcrum for opening. The cover and the text respectively open at an independent fulcrum, and the pipe and the text do not interfere with each other by providing the play in a pipe-text-connecting part.</p> |
