PURPOSE:To achieve easy loading/unloading of a recording disc package, by falling down a required recording disc, lower-order recording discs and a lower half of a case out of loaded recording disc package. CONSTITUTION:A recording disc package 133 has upper and lower cases 134 and 135 in which the flat shape is formed with an octagon resulting from a square with shaped corners. Among loaded recording disc package, a required recording disc, lower recording discs and a lower half of the case 135 only are turned and the recording discs and upper half of the case 134 left at the upper position are fixed in standstill. Thus, a space for the upper-order recording discs and the case for the turning is not necessary and large sized device can not be avoided. |
