<P>PROBLEM TO BE SOLVED: To achieve both the cooling structure for cooling the interior of the device and the easy detachment of the optical disc with a simple structure in an optical disk playback device. <P>SOLUTION: In an optical disk playback device 1, the interior of a disk chamber 21 is separated from the interior ob a main body case 20 by a bottom wall 51 of the disk chamber 21. The bottom wall 51 of the disk chamber 21 is provided with a finger insertion hole 62. The finger insertion hole 62 makes the interior of the disk chamber 21 and the interior of the main body case 20 communicate with each other. When a human detaches and attaches an optical disk 10 in his hand from and to a spindle motor 71, his finger is inserted into the finger insertion hole 62. When the optical disk 10 rotates which is mounted on the spindle motor 71, the air flow generated in the interior of the disk 21 makes the air flow in the interior of the main body case 20 as the finger insertion hole 62 makes the interior of the disk chamber 21 and the interior of the main body case 20 communicate with each other. <P>COPYRIGHT: (C)2012,JPO&INPIT |
