Disk apparatus and disk drive unit including a lock mechanism that is released only when the display unit is in a closed state

A disk apparatus, comprising:

• a body unit including a disk drive for housing a disk-shaped information recording medium having an information recording surface and for recording and/or reproducing information;
• and
• a display unit including a display surface for displaying information, and closed and opened with respect to the body unit in such a way that the display surface is postured face down and up, wherein:
• the body unit further includes a disk insertion-and-ejection mechanism which is movable in a bottom direction of the body unit and inserts and ejects the information recording medium into and from the disk drive, and a lock mechanism locking the information recording medium housed in the body unit;
• a locking state of the lock mechanism is maintained when the display unit is in the open state with respect to the body unit;
• and
• the lock mechanism includes:
• a hooking portion disposed in a slider held so as to slide on the body unit;
• a hooked portion disposed in the disk insertion-and-ejection mechanism and hooked on the hooking portion;
• and a slider spring giving a force to the slider in parallel to a direction where the slider slides and in a direction where the hooking portion hooks the hooked portion.

• a locking state of the lock mechanism is maintained when the display unit is in the open state with respect to the body unit;
• the lock mechanism includes a hooking portion disposed in the display unit, and a hooked portion disposed in the disk insertion-and-ejection mechanism and hooked on the hooking portion of the display unit;
• and
• the hooking portion of the display unit interlocks with an opening operation of the display unit and hooks the hooked portion of the disk insertion-and-ejection mechanism to thereby prohibit the disk insertion-and-ejection mechanism from opening, and the hooking portion of the display unit interlocks with a closing operation of the display unit and unhooks the hooked portion of the disk insertion-and-ejection mechanism to thereby permit the disk insertion-and- ejection mechanism to open.

A disk drive unit which is used in a disk apparatus including a body unit, and a display unit having a display surface for displaying information and closed and opened with respect to the body unit in such a way that the display surface is postured face down and up, comprising:

• a disk drive for housing a disk-shaped information recording medium having an information recording surface and recording and/or reproducing information;
• and
• a disk insertion-and-ejection mechanism which:
• is disposed on a bottom-surface side of the body unit opposite to a surface thereof on which the display unit is disposed;
• is movable in a bottom direction of the body unit;
• and inserts and ejects the information recording medium into and from the disk drive,
• wherein a hooking portion of the display unit interlocks with an opening operation of the display unit and hooks a hooked portion of the disk insertion-and-ejection mechanism to thereby prohibit the disk insertion-and-ejection mechanism from opening, and the hooking portion of the display unit interlocks with a closing operation of the display unit and unhooks the hooked portion of the disk insertion-and-ejection mechanism to thereby permit the disk insertion-and- ejection mechanism to open.
