PROBLEM TO BE SOLVED: To prevent traces from remaining on a document even after the document has been clamped for a long period of time, to enable the operation to be performed only by the simple motion of putting in/taking out the document, and also to enable a ball clip apparatus to be applied to products of various design since only the natural phenomenon of gravity is utilized, and to enable the product design of various applications such as souvenirs to be performed.SOLUTION: This ball clip device is constituted by pinching a clip ball 30 in a guide hole 20 which is formed at a clip body 10, and pinching the document between the clip ball 30 and a lower supporting plate 13. The document is clamped by utilizing a natural phenomenon that the clip ball 30 moves to the lower end of the guide hole 20 by gravity. In addition, the ball clip device can be constituted in such a manner that a magnetic force is formed on the clip body 10 or the clip ball 30 to store wire clips, push pins or the like. |
