纸内部gongbogwan当yidonggwa加载是可能的，并且容易和快速由gongbogwan到球计数，并且更具体地，球被打开以用于存储库的上端部和下端被封闭下端滑动开关附接至鞋盒库到彼此上， 通过使用联接构件的下端部通过使用侧柄，以及垂直最小化它的空间可能的负载，存储多个不同的球（球库的球尺寸，宽度×长度×施加的差的高度”）的 （3,4,5等）存储在一个存储箱中，因此可以方便快捷地进行计数，从而可以最大限度地减少体育活动后的损失。

The subject innovation are possible gongbogwan during transport and loading and easy and fast by gongbogwan to the ball count, and more particularly the upper end portion of the library for storage the ball is opened and the lower end is closed together deposit boxes with a bottom sliding switch attached cuboid the upper and the possible stacking vertically with the lower end engaging member, keep the number of different balls (ball library for the ball specifications apply difference "width × length × height"), the I side handle, as well as to minimize the space for used by the mobile is available and can be an easy and quick count and keep the ball out of the event on one of the library units (3, 4, 5, etc.), that having its shape so as to minimize the loss after physical activity It characterized.
