In the above-described state, the engagement operation piece 9 provided on the operation gear 76
Reference numeral 1 denotes an engagement lever 90 tip as shown in FIG.
It is located at a position facing the end mating surface 111, and
When the dynamic operation shaft 86 is rotated, the engagement operation piece 91
The engagement with the engagement surface 111 causes the rotation of the engagement lever 90.
Movement operation can be performed. Accordingly, the lock lever 28 is rotated.
In some cases, the lock of the disk transfer body 11 cannot be released.
However, operating the manual operation shaft 86 again quickly and surely
Can be unlocked. As described above, the disc ejection according to the present invention is performed.
The mechanism is not only a plunger driven by a power supply,
For example, insert the operation jig from the outside of the housing and move the lock lever
By rotating, the disk transfer body with respect to the housing
Is unlocked, and the ejector lever with accumulated spring force
Move the disc transfer body to the outside of the housing,
Since the disc placed on the can be ejected,
Even if a plunger fails or a power outage occurs,
Move the disk transporter to move the disk
Can be removed to prevent disc damage.
Prevention and reliable protection can be achieved. The disc ejection mechanism according to the present invention is
Disk drive devices such as slave recording devices for computers
When applied to the disk drive,
Disk can be replaced even if the
Can be used without stopping computer operation
It works.
