PURPOSE:To perform holding and release of a disk on a single control surface, and to realize the loading and unloading of the disk, by providing a control knob which is used to hold the disk to a surface to a surface having a disk loading opening. CONSTITUTION:A control knob 38 is set rotatably on a control surface 36 having an opening 37. The knob 38 is put at a position where the opening 37 is not covered when a disk 18 is not held. A part of the opening 37 is covered when the disk 18 is held rotatably. As a result, the state of a disk holding device can be easily discriminated from the position of the knob 38 on the surface 36. At the same time, the thickness of a container 10 is decreased since a rotary arm 27 is operated with a turn of the knob 38 and via a crank mechanism including a shaft 39, an arm 44, a pin 45, etc. |
