Information processing device

An information processing device comprising:

• a casing including a side surface having an opening part and a bottom surface orthogonal to the side surface;
• a frame provided at the bottom surface;
• a disk drive main body configured to be attached to and detached from the frame through the opening part;
• a disk tray which is operable to hold a disk, is capable of being inserted into and drawn out of the disk drive main body through the opening part, and has a hatch operable to close the opening part when the disk tray is inserted in the disk drive main body;
• and a coupling part through which the frame and the disk drive main body are coupled to each other in the vicinity of the opening part, wherein the coupling part is covered with the hatch when the disk tray is inserted in the disk drive main body, and the coupling part is exposed when the disk tray is partially ejected from the disk drive main body, the frame has a pair of guide grooves formed along a direction in which the disk drive main body is attached to and detached from the frame through the opening part, and the disk drive main body has a pair of engaging parts that are engaged with the guide grooves;
• wherein the coupling part includes a first coupling part and a second coupling part, and the first coupling part and the second coupling part are disposed at both ends of the opening part which are on opposite sides of the disk tray;
• and wherein the coupling part has a screw to be passed through the disk drive main body and the frame, and the screw is passed in a direction perpendicular to the bottom surface.
